Questions about car torsion Help me

Passat (260 3200

The explanation is as follows: the torque produced by the engine at 3200 rpm. "n" here can be understood as a force.

"m" can be understood as the distance, that is, the distance from the center point of the drive axle to the tire contact point (tentatively set as a, because the tire diameter is different from car to car, with the difference of tire pressure. a represents the distance from the center point of the drive axle to the contact point of the tire in meters). That is, the force generated by the engine on the ground at 3200 rpm is 260*a (the ground must have enough friction) in Newtons.

The same principle for the EVO car is the same.

The greater the torque of the car, the better its starting ability, acceleration ability, and passability, that is, the more energetic it is.

Passat (260 3200

It means that when the engine speed reaches 3200 rpm, the output torque is the largest at this time, this torque refers to the torque generated on the wheels, which is an important performance index parameter of a car.

Another: sedans focus on high-speed high-torque (gasoline engines), off-road vehicles and trucks focus on low-speed high-torque (diesel engines).

Passat (260 3200

This means that when the engine speed reaches 3200 rpm, it outputs the maximum torque, and the higher this value, the better. Similar to the horsepower of the vehicle.

1、Describe physical concepts differently. Moment refers to the tendency of the force to rotate an object around a rotating shaft or fulcrum; Torque refers to a certain degree of torsional deformation of an object under the action of force. Torque is a special moment that causes an object to turn.

2. The calculation method is different. The moment is equal to the cross product of the radial vector and the applied force; The torque is equal to the product of the force and the force arm or force couple arm; Torque is equal to the product of the force and the force arm.

1) "Vehicle" means motor vehicle and non-motor vehicle.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

Torque is defined as the force in the vertical direction multiplied by the distance from the center of rotation in Newton-meters (torsional force: The force used to twist an object to deform it.

Torque should be called torque and rotational torque in physics, because as a result of false rumors, everyone says that it is torque, and it has been handed down since then.

The meaning of the two is actually the same, torque is just a colloquial term for torque. For example, it is often said how hard it takes to twist the screw, but in fact, it should be said in writing that torque.

<> "What to Know About Torque in Cars.

Car torque is the torque that the engine outputs from the end of the crankshaft. Under the condition of fixed power, it is inversely proportional to the engine speed, the faster the speed, the smaller the torque, and vice versa, reflecting the load capacity of the car within a certain range.

Torque is one of the main indices of the engine, as is power, which is reflected in the performance of the car, including acceleration, climbing ability, and suspension. Let me introduce you to the torque of the car.

Torque is an important parameter of engine performance, which refers to the average torque output from the crankshaft end when the engine is running, commonly known as the "rotational strength" of the engine.

The greater the torque, the greater the "strength" of the engine output, the faster the crankshaft speed changes, and the better the car's climbing ability, starting speed and acceleration. Torque varies with the change of engine speed, too high or too low, the torque is not the maximum, only at a certain speed or in a certain speed range has the maximum torque, this range is the speed or speed range given when the maximum torque is marked.

The maximum torque generally occurs in the range of medium and low engine speeds, and as the speed increases, the torque decreases. The single-bridge position of torque is Newton-meter (n·m) or kilogram·meter (kg·m).

We know that the engine power determines the maximum speed of the car, and the speed of the car is related to the torque, because the engine technology is not the same, the torque often has a relatively large difference, generally speaking, the torque of the turbocharged engine will be larger.

For family cars, the greater the torque, the better the acceleration; For off-road vehicles, the greater the torque, the greater the climbing; For trucks, the greater the torque, the greater the weight of the truck. With the same displacement, the more torque the better the engine. When driving, you will feel that the car can do whatever you want, and you can accelerate if you want to, and the "back feeling" is very good.

Now there is an important statistic for evaluating a car, which is the acceleration time of the car from 0 100 km/h. And this acceleration time depends on the torque of the car's engine. Generally speaking, the highest torque index can be reached at the speed of 2000 4000 minutes of the car, which means that the engine technology of this car is better and the strength is good.

Some cars only reach the maximum torque index at around 5000 rpm, which shows that "power" is not the car's forte.

Let's take a look at what torque is. Torque is also known as torque. is a unit length arm that rotates around the axis while the other end exerts a force perpendicular to the direction of the arm.

This may seem jerky, but we can illustrate with an example: we need to use a wrench to tighten the tire screws, and we use force on the handle of the wrench, so the force exerted on the screws is called torque.

The unit of torque is Newton per meter. Its level determines the quality of the vehicle's ability to accelerate sharply, and whether the burst at the start is powerful.

Automobile Torque When we look at the performance data of a car, in addition to the amount of horsepower, there is also a noteworthy performance that is the amount of torque. Torque is the torque output of the engine at running speed, to put it bluntly, it is the output of the engine. Torque or torsion is said for objects in rotational motion, because the driving force of the engine, transmitted from the flywheel through the gearbox to the wheels, is in a rotating state.

For the driver, what can be felt is the acceleration force of the vehicle, so we say that a car is strong because it feels the acceleration force generated by the strong torque of the engine. How to Interpret Torque Data Usually we see torque data like this: This means that the engine will have the maximum torque at 4400 rpm.

Generally speaking, the torque output of the engine will be different at different speeds, but judging from the above data, it is not the torque that the engine has at 4400rpm. Although the torque output of the engine varies with the engine speed, the torque is mainly related to the engine load, that is, the depth of the throttle pedal. So the above data should be interpreted like this:

When the engine is at full load at full throttle at 4400rpm, there will be maximum torque. Torque output characteristics The torque of the engine is not only the amount of force, but also related to the acceleration of the vehicle, and related to the climbing and load capacity (load capacity also involves the chassis setting). Different engine designs will have different torque output characteristics, some engines have more torque at low speeds, some have higher torque at high speeds, and some turbochargers have plateau torque output characteristics with high torque in the full speed range.

In the general use state, the car is mostly driven at low speed in the urban area, or at high speed on the highway, and the engine is mostly running at medium and low speeds, so the engine with low speed and high torque is most suitable for general daily use. However, for competitive cars that often use high revs, engines that emphasize high rpm and high torque are often used. Torque & Horsepower The engine horsepower curve is plotted based on the torque value measured during the test.

The blue one is the torsion curve, and the red one is the horsepower curve. What is the relationship between torque and horsepower? In the engine test, the torque value can be measured, and the horsepower is calculated from the torque and the engine speed, so the torque and horsepower are obtained in the same test.

As already mentioned in the horsepower chapter, horsepower is actually a unit of power, not force; And power = force * speed , horsepower is power, in rotational motion, torque is power, and rpm is speed, so horsepower is the product of torque and engine speed. However, it involves the conversion of units and rotational and linear motion, so the detailed equation is not listed here. Common Units There are three common units of torque, kg-m, lb-ft, and nm.

In Taiwan, kg-m is generally used as the torque unit, Europe is often labeled in nm, and in North America, lb-ft is mostly used as the torque unit.

Engine torque is the force that pushes the vehicle, whether it is accelerating up a hill from a standstill, resisting air resistance at high speeds, it is all coped with by engine torque

But the more torque, the better.

You can take a look at the HDP program, which can increase a lot of torque and horsepower after power upgrades, and also provide insurance, professional and reassuring.

...Horsepower and torque are important parameters of the engine, and the maximum horsepower and torque of various engines are indicated in the product catalogs of each company. Let's start with torque

.Torque, also known as torque, is the moment that rotates the shaft. In Japan, the common unit of torque is kg·m, and the international standard unit is n·m.

To better understand the concept of torque, here are a few examples. For example, if the length of the button wrench is 1 m, and a force of 1 kg is added to one end of the torque wrench, the tightening torque of the screw will be lkg·m. If the length of the torque wrench is 0 5 m, a force of 2 kg must be applied in order to obtain a torque of 1 kg·m.

The reverse is also true, if the driving torque is the same, the farther away from the center of rotation, the less force is generated.

.The term torque is used in a variety of situations, and it is common to find provisions such as "the tightening torque of this screw shall be kg·m" in technical documents. On motorcycles, torque is often used to express the driving torque of the crankshaft, and the torque of the crankshaft is the source of the driving force of the motorcycle.

.The torque generated by the engine varies at various speeds. During engine operation, the engine output torque is related to various parameters of the engine, such as intake efficiency, combustion, exhaust efficiency, valve phase, carburetor size, etc.

Most of these parameters are related to the speed of the engine, so the torque of the engine is very closely related to the speed. When a motorcycle is turning, many skilled motorcycle riders are able to reduce the turning radius of the motorcycle by taking advantage of the change in engine torque felt by their body to cleverly accelerate and make the rear wheel of the motorcycle slip properly.

.In the actual operation of the engine, the change of engine speed can cause the change of torque accordingly, and the output torque value changes. The relationship between engine torque and speed is also different depending on the engine model, and the relationship between button torque and speed is often called the torque characteristics of the engine.

Automobile torque: The torque output of the engine from the end of the crankshaft.

Torque is the force that causes an object to turn. Engine torque is the torque that the engine outputs from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed, the faster the speed, the smaller the torque, and vice versa, it reflects the load capacity of the car within a certain range.

The higher the torque of the car, the more powerful the engine.

In the middle and low speed range of the engine, with the increase of gear, the torque will decrease, the greater the torque of the car, the higher the acceleration, climbing, and load capacity of the car, so the stronger the engine power. If the displacement of the engine is the same, the more torque the natural one is when choosing, the better.

Knowledge of automotive torque

1. Automobile torque is a very important indicator of the engine's acceleration ability, which refers to the work done by the reciprocating motion of the piston in the cylinder.

2. The ability of the car to start from a standstill and low speed, and to accelerate with Li Xiao has a lot to do with the torque debate, the engine torque is large, and the chain will be more stable when driving at low speed, and the faster it will be when it accelerates.

3. Automobile torque is not only an important reference index in the engine, but also an important reference in the car, if the engine displacement of the car is the same, you can judge by looking at the torque, the greater the torque, the better.
