Four wheel drive masters, please enter the gear row car or front wheel drive? Or is it a good combin

The disadvantage of the front drive is that the turning is not very smooth! Tooth rowing, the strength is larger, and it must be always warranted! The precursor and the tooth row are in conflict with the parallel of the force! (Do the test to get it) hehe, personal opinion, good tooth arrangement!

Let's put it this way, if you want to have a faster lap time, you can solve the problem of the difference in speed between the left and right wheels, and now it is almost the bottleneck, and the teeth are good.

As a mechanical transmission, too many gears represent a decrease in transmission efficiency and an increase in friction, and the gear row undoubtedly increases friction consumption.

Seeing a friend in the gear to install bearings, to be honest, this is also a problem, handmade, the coaxiality is difficult to grasp, will cause the gear round runout to increase, reduce the transmission efficiency.

The perpendicularity of each gear shaft, the parallelism of several gear shafts, and the errors in which all produce power loss.

I don't know if there are any friends who will compare the same car with the transmission rod transmission and the gear row transmission, hehe, is the gear row really improve the performance.

The front-wheel drive car is more stable than the gear row, and the smoothness is high, but the speed and torque are not strong enough, so the car with the gear row is generally the majority.

Friends who know a little about cars should know that cars are divided into three driving modes: front-wheel drive, rear-wheel drive and four-wheel drive. But some people say:

Is it true that the front-wheel drive has poor handling, the four-wheel drive is fuel-efficient, and the rear-wheel drive car is the king? Today, I want to talk to you about those things about car drive, and see what are the advantages and disadvantages of front-wheel-drive, rear-wheel drive and four-wheel drive, and what are the differences? The prospective car owner saw it clearly.

Pre-precursor. Pull the car and run.

The front-wheel drive is mainly responsible for steering and driving by the front wheels, and it is also the most common driving method, covering the widest range, and is mostly used in ordinary family cars, such as Corolla, Focus and Lavida, etc. Because the engine is in the front of the body, plus the transmission shaft connecting the rear wheel and some parts are omitted, the power output is direct, the cost is low, the space occupied is small, the transmission efficiency is high, and the fuel consumption is low. However, because the front of the body bears most of the weight, the front-wheel drive car has poor handling, understeer, and pushes the head in the extreme cornering state.

Front and rear wheel drive. Push the cart and run.

The front-rear-wheel drive engine is arranged at the front of the body, driven by the rear wheel drive, and there is a propeller shaft between the engine and the drive wheels. The form of front-wheel drive and rear-wheel drive is mostly used in luxury and sports sedans like BMW 3 Series and Ford Mustang. The advantage of rear-wheel drive is that it better distributes the weight of the front and rear of the body, has a better handling and driving stability than the front-wheel drive, has strong acceleration ability, and has good sports performance.

But also because of a more complex transmission system, the cost of the rear drive will be higher than the front drive, and the space in the car will be limited, especially the rear row in the middle of the foot has a protrusion, the drive shaft increases the quality of the vehicle, the power loss hits, and the fuel consumption is also higher.

Four-wheel drive full-time four-wheel drive, time-sharing four-wheel drive, timely four-wheel drive.

Four-wheel drive is the drive structure that drives the vehicle by four wheels together, it has the efficiency of front-wheel drive and rear-wheel drive control, and is also divided into three ways: full-time four-wheel drive, time-sharing four-wheel drive and timely four-wheel drive. Four-wheel drive vehicles have excellent driving stability, cornering ability and ability to get out of trouble, providing better off-road performance. However, due to the more complex structure, the four-wheel drive consumption will be more, theoretically it will consume more fuel than the front-wheel drive, rear-wheel drive, and the maintenance will be relatively troublesome.

Therefore, the four-wheel drive system is generally used in off-road and sports performance models, such as Golf R, Audi RS3 and so on.

So, when it comes to which drive method is more suitable for you, you have to start according to your needs and preferences. If it is just a city commuter, large space, fuel and money-saving, economical and practical front-wheel drive car is enough; If you are more concerned about handling, you can consider rear-wheel drive cars; If you are in the north where the road is prone to ice in winter, or if you like outdoor off-road, then the four-wheel drive model is a good choice.

The difference between front-wheel drive, rear-wheel drive, and four-wheel drive.

Of course, it is a rear-wheel drive car, and the rear-wheel drive car is generally more powerful than the front-wheel drive car, and the front-wheel drive is characterized by excessive turning, while the rear-wheel drive car is underturning.

Because the four-wheel drive vehicle on the track relies on the interaction between the guide wheel on the front buffer (bumper, dragon head) and the rear buffer (phoenix tail) and the track (lane) wall to change the direction of travel, so whether the car can drive smoothly at high speed is closely related to the reasonable assembly and adjustment of various components such as the dragon head and the phoenix tail.

After the guide wheels of the dragon head and phoenix tail are installed (including the middle wing and anti-roll bar), the more flexible the rotation, the lower the forward resistance of the four-wheel drive vehicle, and the faster the speed. In order to reduce the rotational resistance of the guide wheel, an appropriate amount of grease (butter) can be added between each guide wheel and shaft.

Obviously, four-wheel drive vehicles are all driving wheels on all four wheels, how can there be a problem of rear wheel drive or front wheel drive?

A four-wheel drive vehicle may have two drive modes, rear-wheel drive or both front and rear all-wheel drive. The front wheels can be driven without drive as required.

At present, in the domestic automobile market, compact cars and medium-sized cars are mostly front-wheel drive models, and the front wheels are responsible for steering and driving. Rear-wheel drive vehicles are mostly sports models, while large luxury cars are mostly rear-wheel drive. The steering of a rear-wheel drive car is separate from the drive.

Compared with the propeller shaft of the front drive, the loss of energy consumption is larger, so the fuel consumption type is higher. At the same time, because this is the same as the traditional propeller shaft, the protrusion of the rear row is usually relatively high, which will affect the ride comfort of the middle passenger.

Rear-wheel drive cars have one advantage over front-wheel drive cars, and that is handling. Rear-wheel drive vehicles need the drive shaft to provide power, so the drive shaft can play a buffering role at some times, such as the car suddenly loses power, the drive shaft will continue to transmit part of the power under the action of inertia, and will not be directly powered off like the front-wheel drive car. So after driving, the driver will not feel too strong a power failure, and the drift is done after driving.

It also feels more relaxed when driving uphill, like someone is pushing it.

The reason why front-wheel drive cars are more popular is not because consumers don't like rear-wheel drive cars, but because rear-wheel drive cars tend to only appear in luxury or sports brands above 300,000 yuan, while in the domestic car market below 300,000 yuan, front-wheel drive cars often occupy most of the market share. In the actual use of the car, the advantages of fuel economy and large front space are more in line with the actual needs of consumers, and the perception of handling and driving pleasure is not obvious. For front-wheel drive vehicles, the engine is in front, and the power does not need to be transmitted to the rear wheels through the propeller shaft, so there is less energy loss, so the fuel economy is good.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

I think the rear-wheel drive car is better, because the power system of the rear-drive car is more sufficient, and then the acceleration of this car is also very fast in 100 meters, and the experience is very strong when driving, and there is a feeling of pushing back, which is particularly cool.

For families, I prefer to opt for a front-wheel drive car. The advantage is that it has a larger space, is easier to maintain, and is more slippery when walking in snow.

I think the rear-wheel drive car is better, the rear-wheel drive car has lower fuel consumption, enough for daily use, and the kinetic energy is also guaranteed.

The front wheel drive is to pull the front wheel of the cart to do the work, the rear drive is the rear wheel of the cart to work, and the four-wheel drive is also divided into time-sharing four-wheel drive and full-time four-wheel drive.

The stability of the four-wheel drive is good, and it can be better reflected in snow days.

The four-wheel drive is much better, but the four-wheel drive handling is better if it is more rear-wheel-drive.

Four-wheel drive means that the vehicle has been maintained in the form of four-wheel drive throughout the driving process, and the engine output torque is distributed to the front and rear wheels in a fixed proportion, which can have better off-road and handling performance at any time, but can not make torque distribution adjustments according to road conditions, and fuel consumption is higher. The time-sharing four-wheel drive is controlled by the computer chip two-wheel drive and four-wheel drive switching, in the normal road, the vehicle is driven in two-wheel drive mode, encountering off-road road or wheel slipping, the computer will detect and automatically distribute the power to the other two wheels. For the time-sharing four-wheel drive mode, the quality of the control program will affect the intelligence of the drive mode switching.

Front-wheel drive vehicles are easier to maneuver because the drive wheels and steering wheels are together, so the position of the front wheels is always pointing in the direction the vehicle is going to drive when steering.

In other words, the car will drive wherever you are pointing. Because the engine is in the front of the car, the weight of the front part is concentrated, which ensures that the driving wheels have enough grip, so you don't have to think too much about driving a front-wheel drive car.

Moreover, the engine and transmission system of the front-wheel drive car are concentrated in the front of the car, which reduces the cost of the vehicle itself, which is also the reason why the current cars below 200,000 yuan are front-wheel drive. Although the front-wheel drive car is easy to handle, due to the excessive weight of the front part of the front-wheel drive vehicle, the weight ratio of the whole vehicle is uneven, and the front of the car is too heavy.

If the speed is too fast when entering a corner, the front of the car will continue to drive in a straight direction under the action of inertia, which is usually called 'pushing the head'. This phenomenon can cause accidents as a result of the vehicle not being able to follow the expected route. It is not difficult to solve this problem, the main way is to slow down the car speed, release the throttle accordingly, and return to the steering wheel at the same time, so that the driving line becomes as smooth as possible, that is, in the case of conditions, the angle of entry becomes larger, so that the force of the vehicle becomes smaller, and the corner will turn smoothly.

Rear-wheel drive is the originator of the form of automobile drive, and many luxury cars and high-performance cars currently choose rear-wheel drive. The advantage of rear-wheel drive vehicles is that the weight distribution is close to balance, the vehicle is relatively stable, and although the cost is high, it is easy to maintain. When the car accelerates, the center of gravity of the whole vehicle shifts backwards due to the action of inertia, and gravity is concentrated in the vehicle.

To put it simply, one is that you are pulling a two-wheeler, and the other is that you are pushing a two-wheeler, and when you pull the two-wheeler through a sharp bend, you pass, and the two-wheeler does not pass smoothly. The cart cornering is easier to control. But on a snowy day, if you step on the ice, it's even harder to push if you go to push the cart.

This is a hard indicator and a manufacturer's selling point, which is clearly stated in the brochure.

If the front compartment is opened, the transverse engine is mostly front-wheel-drive, and the engine front is that the intake and exhaust ducts are in front or distributed in the front and rear, and the longitudinal ones are on both sides.

If the front transverse engine has a drive shaft on the rear axle (the drive shaft can be seen from the inside of the rear wheels from the rear), it is a timely four-wheel drive. The front longitudinal engine is basically rear-wheel drive, with the front drive shaft (from the front of the car to see the drive shaft on the inside of the front wheel) is mostly full-time four-wheel drive or time-sharing four-wheel drive, as for which it is not easy to distinguish, you have to look at the cockpit transfer case handle, with 4H marked for full-time four-wheel drive, only 2H, 4hlc or 4LLC and so on for time-sharing four-wheel drive.

There is no good or bad for this. The front drive is to drag the whole vehicle, and the rear drive is to push the whole vehicle. In terms of car driving stability, the front wheel drive is better.

Because the front-wheel drive concentrates the transmission system of the car, the transmission shaft and rear drive device are omitted, so that the cost of the whole vehicle is reduced. In terms of power performance, it is true that a large driving force can be obtained. Because the role of the final reducer is mainly to reduce the speed and increase the torque, the car of the rear drive can generally arrange the main reducer farther away from the gearbox and the engine, so the driven gear distribution circle in the main reducer can be designed to be larger, and a larger transmission ratio can be obtained.

However, the transmission shaft and drive axle are added, which increases the weight of the whole vehicle and increases the cost. Generally speaking, fast, lightweight, and comfortable passenger cars use front-wheel drive. Passenger cars and trucks need a lot of drive in order to pull more passengers and goods, sacrificing speed in favor of rear drive.

If you want good power, naturally the four-wheel drive feels the best.

The front-wheel drive transmission is direct and the efficiency is better, but because the left and right output shafts are not of equal length, there will be an imbalance in the power of the left and right wheels under high torque conditions, resulting in loss of control, and most of the weight is concentrated in the front of the car, and the cornering ability will become worse.

Therefore, the horsepower of more than 300 is basically rear-wheel drive, and the higher is simply four-wheel drive.

As for the front wheel, the main thing is that it is cheap, and it is said that the performance is hehe. For example, Megane and Civic R broke the record called the fastest front-wheel drive car, and the top few in the ranking were either four-wheel drive or rear-wheel drive

Is it better to have a front-wheel drive car or a rear-wheel drive car? What's the difference between the two? After reading the knowledge.

The difference between a front-wheel drive car and a rear-wheel drive car is that the front-wheel drive vehicle is powered in the front and the rear-wheel drive vehicle is powered in the back. Of course, the rear-wheel drive car is better, and the power is leveraged.

The difference between a front-wheel drive car and a rear-wheel drive car is the difference in the drivetrain; Front-wheel drive vehicles are powered by the front wheels, while rear-wheel drive vehicles are powered by the rear wheels. The pursuit of good operation feel of the front drive, the pursuit of rapid high horsepower rear drive good.

The front-wheel drive car is powered by the front wheels, and the rear-wheel drive car is powered by the rear wheels.
