Urban Dirt Bike What s different about hardcore dirt bikes?

Urban SUV: generally using load-bearing body, low displacement, low ground clearance, mostly using timely four-wheel drive or two-wheel drive, no low-speed four-wheel drive and most of them do not have locking devices, more suitable for running highways and non-paved roads of general difficulty, and poor rescue and escape capabilities. Most of the tires used have a relatively small flat ratio, low noise, but better comfort.

Hard-core off-road: mostly non-bearing body, mostly using large-displacement gasoline or diesel engines, high ground clearance, some also have chassis lifting devices, basically full-time four-wheel drive or time-sharing four-wheel drive, low-speed four-wheel drive, and differential locking devices, such as the Jeep Wrangler Rubicon has a mechanical four-wheel drive device and has three differential locks for the front axle and rear axle, theoretically as long as one tire hits the ground can get out of trouble. Suitable for unpaved roads and extreme off-roading.

The tires mostly use off-road tires with a relatively large flat ratio or all-road tires, which have disadvantages of high fuel consumption, high noise and poor comfort.

Pro, it's a pleasure to serve you, the hardcore off-road vehicle ORV (off-road vehicle), is a high-performance off-road vehicle, referring to a real off-road vehicle. Refers to an off-road vehicle that can be used on rough ground.

At present, the Jeep Wrangler, Mercedes-Benz G-Class, Land Rover Defender, Land Cruiser (Land Cruiser) and the early Hummer (bankrupt) are all representative models of hard-core off-road vehicles, these models are characterized by the use of a large number of straight lines in the exterior design, on the one hand, the straight lines can depict the memory temperament of the hard-line, on the other hand, the square design can meet the actual use needs of off-road space and safety; In use, these models have quite strong off-road performance, not only high ground clearance, strong passability, but also a strong power system.

A classic hardcore off-road vehicle must have the following four characteristics at the same time:1Non-load-bearing body (i.e. with body girders, like a truck); 2.

The front and rear hard axles, that is, the integral axles (the front and rear wheels are connected to the left and right wheels by a single axle); 3.mechanical transfer case (with low-speed four-wheel drive mode, usually with differential lock); 4.Large-displacement off-road engines with low revs and high torque (usually above displacement).

Urban off-road is a gimmick for those pseudo-off-road SUVs that don't have much off-road ability to highlight their functionality.

Off-road vehicle (ORV) is a type of car specially designed for off-roading, mainly referring to off-road vehicles that can be used on rough ground.

The main features are a non-load-bearing body, four-wheel drive, a taller chassis, tires with better grip, a higher exhaust pipe, more horsepower and a thick, sturdy bumper. Off-road vehicles can not only adapt to various road conditions in the wild, but also give people a rugged and heroic feeling, in the city, there are also many people who like to drive off-road vehicles.

Off-road vehicles are members of the military car family, and most of them have a certain off-road driving ability. That is to say, these cars can be driven on very poor quality roads or in areas and battlefields where there are no roads at all, and later, in order to meet the needs of combat, a military vehicle with stronger off-road ability appeared, which is commonly known as military off-road vehicles.

This kind of car is a model of high-end off-road vehicles, but due to the lack of a low-speed torque amplification mode, it is not actually suitable for low-speed extreme off-roading. That's why it's called an urban buggy.

Types of common urban off-road vehicles (also known as "SUVs"):

It is further divided into the following categories:

1. Two-wheel drive SUVs (divided into front-wheel drive and rear-wheel drive); Front-wheel drive SUVs can cost much less than rear-wheel drive SUVs.

This kind of car is generally seen in low-end SUVs, especially SUVs with only front-wheel drive, because they cannot be anti-skid at all, so the value of actual off-road is not too high.

2. Timely four-wheel drive, intelligent full-time four-wheel drive, intelligent four-wheel drive SUV;

This kind of car, in order to save the device, strengthen the efficiency of the multi-front wheel main drive wheel, the front and rear axles are connected by a viscous multi-piece coupling device. However, there can be electronic limited slip between wheels, which is generally very weak.

There is also a kind of locking switch device, that is, a specific conversion device is needed to strengthen the strength of the electronic locking device, and at this time there will be an "auxiliary limited slip", which has a good anti-skid effect. Assisted Slip Limit: Electronic four-wheel assisted Slip Limit, referred to as "BLSD".

It's a great fit for most people and is the mainstream of the market, but it's not really an off-road vehicle, especially if it doesn't have a "Assist Limited-Slip" selection button.

3. An SUV with three four-wheel drive modes that can be switched, timely intelligent full-time intelligent four-wheel drive, and four-wheel drive limited slip, which has a 2H AWD 4H lock mode. The 2h here refers to the two-wheel drive (mostly rear-wheel-drive) mode; AWD stands for Just-in-Time 4WD Mode; 4H Lock all-wheel drive mode with Electronically Assisted Slip Limit (BLSD).

This kind of car is more powerful than the general timely four-wheel drive SUV, but because the performance is not recognized by the outside world, the relative price is cheap, and the price will be relatively high.

4. Full-time all-wheel four-wheel drive SUVs generally have **limited slip devices or **differential locks.

There are also full-time all-wheel four-wheel drive SUVs, which are more advanced, including a ** limited slip device and an inter-wheel electronic assisted limited slip device, and even an inter-wheel differential lock.

Which urban SUV is better for off-roading? Look at the "Horizontal Comment" of the Chewen Society, buying a car is more transparent, and the Chewen Club will answer for you!

Urban off-road is actually a comfort-oriented off-road vehicle, which is different from a pure off-road vehicle with a single function that is purely used for off-road off-road, such as the Jeep military Hummer and other pure off-road vehicles.

Not all SUVs can be called hardwave off-road vehicles, majestic and powerful do not necessarily become synonymous with hardwave off-road vehicles, but what characteristics do they have to be called hardwave off-road vehicles? Classic representatives of hard-line off-road vehicles include Jeep Trojan, Mercedes-Benz G, Toyota Land Cool Lujie, FJ Cool Lujie, Nissan Tu Lao Lu, etc. These models all give a large and majestic visual effect on the outside.

In addition, Suzuki's Luggage Ni can be said to be a tough off-road car, but it is indeed tall, but not big, so the hard-core off-road car is not necessarily domineering in appearance and powerful.

What are the characteristics that make a tough off-roader? The non-carrier body design, the so-called non-carrier body, is simply understood as the body is separated from the chassis, and the engine, transmission, suspension system and other components are directly mounted on the chassis girders, and then the body is covered on the chassis girders. As a classic symbol of hard-wave off-road vehicles, the non-load-bearing body design is equipped with heavy accessories such as front and rear bumpers and side bumpers to prevent damage to the body.

If you want to play off-road games, you have to choose a 4-drive model. It is mainly divided into time-of-time 4-driver, time-sharing 4-driver, full-time 4-driver, and 4-driver system developed by some large automobile companies.

As a hard-line off-road vehicle, it will encounter various road conditions after "going off the road", and even go over mountains and mountains in search of unprecedented scenery, which requires a large-displacement engine that can guarantee sufficient power. It is not the hardliners who have this talent, but the "tough guys" in off-road. Large displacements alone will not work.

As an off-road vehicle, it is inevitable to hit a steep slope or a sinking car. Sufficient force is required at low speeds. This is what we often call "low torsion".

The difference with the differential is just one word, easy to confuse, but these are two "objects". In layman's terms, a differential is used to distribute power, allowing the left and right wheels to rotate at different speeds, thus guaranteeing the maneuverability of the rotation. If one wheel falls into a pit, the other wheel cannot be torqueed either, and the speed lock is used when losing power.

A differential lock is a device that limits the difference in power output of the differential output terminals, which is equivalent to canceling the function of the differential and locking the two output terminals of the differential together.

Hardwave off-road vehicles generally have a large minimum deviation interval, and the size of this value directly determines the quality of passing performance. Especially if it is easy to support the ground. Performance in this area can be improved by replacing the tires.

The minimum distance interval for light off-road vehicles is generally more than 220 mm, and of course the distance interval can be increased by replacing the large wheels or replacing the shock absorbers for long distances. As another important sign of hardwave off-road vehicles, full-size spare tires undoubtedly play a very important role in off-road, and even some off-road players have the habit of installing double spare tires when passing through in depth to ensure the safety of the vehicle.

The characteristics of these off-road vehicles are that their chassis is very high, and the driving is very smooth, and the space in the car is also very large, which can put a lot of luggage, so they are popular with people.

The shape of this kind of car is relatively good-looking, and it is very atmospheric, the power is relatively strong, the kinetic energy is particularly good, and the sense of design is very strong.

The overall power of the hard-core off-road vehicle is very powerful, and there is also an improvement and improvement in the handling ability, which is also relatively cool outside. Very good value for money.

The off-road vehicles on the market are generally very tall in appearance, and the wheels are also very large, the body is also very large, and the space inside is also very large, and the appearance is very attractive.

The difference is very large. The power system is different, the engine and gearbox are different, the acceleration is different, the fuel consumption of these two cars is also different, and the driving experience is different.

Reflected in the performance of the two cars when walking on mountain roads, urban SUVs may not be particularly energetic, but hard-core off-road is very suitable for walking some mountain roads.

The performance is different, the power is different, the model is different, the height of the chassis is different. The body is different.

There is an essential difference between an urban SUV and a pure off-road vehicle, that is, whether it adopts a load-bearing body structure.

Urban SUVs tend to be electronic four-wheel drive, and pure off-road vehicles pay more attention to passability.

Off-road vehicles are generally non-load-bearing bodies, that is, with girders. This kind of girder is generally rectangular or trapezoidal, which greatly improves the rigidity of the body. Urban SUVs generally use a load-bearing body.

The advantage of the non-load-bearing body is that the body has high strength, is safer, and is suitable for off-road on rugged roads, but it is heavy, uses more steel, and is expensive in cost.

With the development of automobiles, the term off-road vehicle gradually became unfamiliar, and was replaced by the new term SUV. The full name of SUV is sportutilityvehicle, which means sport utility vehicle in Chinese, mainly refers to those four-wheel drive off-road vehicles with avant-garde design and novel shape, to a certain extent, both the comfort of a sedan and the off-road performance of an off-road vehicle.

The off-road vehicle is mainly driven on the non-paved road, and its biggest feature is that it has a strong passing capacity, and also has a certain cargo carrying capacity. Because of its non-load-bearing body and integral axle design, it makes driving safer and more reliable. But it's often less sporty, and it sacrifices comfort.

In addition, pure off-road vehicles** are more expensive.

1. Body structure. Professional hard-core off-road vehicle, using a non-load-bearing body structure, also known as a girder body. As the name suggests, it has a special force girder for the installation of suspension, engine, transmission and other mechanical structures.

Corresponding to the non-load-bearing body is the load-bearing body, while the load-bearing body does not have a separate stressed beam, and the whole vehicle is fully stressed.

2. The appearance of the SUV is fashionable and good-looking, and it is easy to operate and drive. The driving comfort of off-road vehicles is not as good as that of SUVs, and the driving operation needs to be a little skillful!

Precautions when driving an off-road vehicle:

1.Off-road . The car is a rough car, but you must not be careless when driving an off-road vehicle, nor can you be arrogant.

When playing off-road mode, you should keep a calm mind, look around, and decide on the appropriate driving gear before driving. When entering a dangerous area, remember the word "slow".

2.Remember that mud splashing and wheel spinning and slipping are both off-road taboos, and you should know that it is difficult to retreat, and when there are individual wheels slipping in the mud, you should stop immediately. The best thing to do is to go back and start again, because recklessness is often the culprit of cocooning.

4.Braking should also be gentle, and braking suddenly or abruptly will only cause the vehicle's center of gravity to suddenly shift to the front wheels, and it is easy to lose control when encountering a downhill slope. It is even more dangerous if the brakes are too sharp and the wheels are locked, because the car loses its steering function and the result of coasting is also a loss of control.
