1. Introduction
wheelbase
wheelbase (mm): shaft torque, it is the midpoint of the two wheels adjacent the same side of the vehicle by , and the distance between the plane perpendicular to the two vertical longitudinal symmetry of the vehicle. Simply put, it is the front axle center to center distance of the rear axle.

First, the train wheelbase:
locomotive or other vehicle wheelbase. It is divided into fixed and full-wheelbase wheelbase.
total wheel axle distance i.e. most of the last axis, affecting train “carousel length” of the main parameters.
wheelbase, in the train operation is always parallel to the axle distance of most of the last shaft. As long wheelbase, when turning on the rail pressure increase, and even lead to derailment.
Second, the car and wheeled tractor wheelbase:
Simply put, it is the car (or tractors) front axle rear axle center to center distance of
[123. ] wheelbase is the central point of the two wheels adjacent the same side of the vehicle by, and perpendicular to the distance between the two vertical longitudinal plane of symmetry of the vehicle.
After the vehicle length is determined, the wheelbase is the most important factor affecting the passenger space, because the majority of the car 2 and the passenger compartment of the passenger seat 3 is disposed between the front and rear axles . Long wheelbase longitudinal space so that the occupant is increased, will greatly increase the comfort of the foot space of the vehicle impact. Although the wheelbase is not the only determinant of interior space, but it is the fundamental factor.
does not deny the short wheelbase car can be made up of small interior space through some design problems, but overall is still limited.
Meanwhile, the length of the wheelbase of the car comfort, handling stability of a great impact. In general, the higher the level the longer wheelbase sedan. The larger the wheelbase, the greater the length of the cabin, the occupant seated more spacious seating space, anti-pitch and yaw better performance, while increasing the long wheelbase straight road cruising stability, decreased flexibility steering, the turning radius increases, carFlexibility is also poorer. We must make a choice between stability and flexibility to find the right balance. Of course, in the long-wheelbase high-end cars, such disadvantages have been offset by other high-tech devices.
3, the vehicle wheel base length
From a design perspective, the wheelbase is a very important parameter, which is closely related to performance of the car. Wheelbase determine the location of the center of gravity of the car. Thus, once changed wheelbase cars, it is necessary to re-design of the overall arrangement, particularly the drive train and the size of the body part, the suspension system re-adjust the parameters of springs and shock absorbers, steering the steering rod size ladder. Ago while changing the wheelbase can also cause changes in the axle load distribution, which must be considered, handling and ride comfort of the impact of these factors on the car braking. So in the automotive technical performance table will certainly be marked with a wheelbase of this parameter, which proves itself as a reference is very important.
From the practical view, the length of the wheelbase directly affects the length of the car, thereby affecting the internal space of the vehicle. Generally in the mini-car wheelbase 2200mm or less, it is less leg room in the back seat, if it is an adult sitting in the back seat, it is usually in the back of the knee to the top of the seat in front, legs simply not open, the feeling of sitting in the car gives a depressing, not to mention the more it will be used as official cars and taxis. With respect to the short wheelbase mini-car, ordinary car and intermediate cars is generally longer wheelbase, rear seat space is relatively large and therefore some adults may be more relaxed sit down wheelbase, so it’s a family car whether it is done car, or do public service vehicles and taxis, are welcomed by the people.
After determining the vehicle length, the seating space wheelbase affecting the most important factor in the occupant space of the longitudinal length of the wheelbase is increased, it will greatly increase the comfort of the foot space of the vehicle impact. Although the wheelbase is not the only determinant of interior space, but it is the fundamental factor. At the same time, a significant impact on the comfort of the length of the wheelbase of the car, handling stability. In general, the higher the level the longer wheelbase sedan. The larger the wheelbase, the greater the length of the cabin, the occupant seated more spacious seating space, anti-pitch and yaw better performance, while increasing the long wheelbase straight road cruising stability, decreased flexibility turn, turningRadius increases, the worse the vehicle maneuverability. We must make a choice between stability and flexibility to find the right balance. Of course, in the long-wheelbase high-end cars, such disadvantages have been offset by other high-tech devices.
Finally, we look at short and long wheelbase, the operating performance of the vehicle have any effect. Short wheelbase cars, car length is short, the quality is small, and longitudinally through the minimum turning radius is small radius, vehicle maneuverability like. However, if the wheelbase is too short, the length of the carriage becomes insufficient, rear suspension (from the last line of the vehicle and the rearmost axle of the vehicle) will be too long, it will cause a large oscillating longitudinal acceleration and braking ﹑ mass when driving uphill or – transferring, its handling and stability will deteriorate. If the wheelbase is too long, it will make the body length increases, so will the rear reversing blind spot is too large, if not increase reversing radar, reversing for the novice is a severe test.
4, car wheelbase Category
In practical use, the length of the wheelbase directly affects the length of the car, thereby affecting the internal space of the vehicle. According to the degree of the length of the wheelbase, the car can be classified as micro-cars, small cars, compact cars, midsize luxury cars and carts.
micro-car
generally in the mini-car wheelbase 2400mm or less, it is less leg room in the back seat, if it is an adult sitting in the back seat, it is usually in the front of the knee to the top the back seat, legs simply not open, sitting in the car gives a feeling of oppression, not to mention its use as official cars and taxis. For example: Chery QQ3, Changan Benben, Geely Panda, these cars wheelbase is about 2340mm, there are smaller SMARTFORTWO, wheelbase only 1867mm.
a small car
generally refers to the 2400-2550mm wheelbase between the models is called a small car, for example: Honda Fit, the Toyota Vios, Ford Fiesta and so on.
compact car
generally refers to the 2550-2700mm wheelbase between the models called compact car, this level models are sedans mainstream models, such as: Volkswagen Jetta, Toyota Corolla, Fute Fu gramSri Lanka, Honda Civic and so on.
in the
car
generally refers to the 2700-2850mm wheelbase between the models referred to in the car, this level models are usually used along with household and business models, such as: Honda Accord, Toyota Camry, Volkswagen Magotan Mazda 6 Rui wing like.
in the
large car
generally refers to the 2850-3000mm wheelbase between the models referred to in the large car, this level models are usually commercial vehicles of mainstream models, such as: the Audi A6, BMW 5 Series Mercedes-Benz E-class, Volvo S80 and so on.
luxury car
usually refers to more than 3000mm wheelbase model called luxury car models, this level models is usually the rich and choice, and prices are more than one million yuan basic, such as: Mercedes-Benz S class, BMW 7 Series, Audi A8 and so on.
