The role of the front and rear wheels of special vehicles

The automobile wheelbase is the distance between the centerlines of the trajectories left by the wheels on the ground. If the ends of the axle are double wheels, the wheelbase is the distance between the two center planes of the two wheels. The car's track is divided into the front track and the rear track. The front track is the distance between the center planes of the front wheels and the rear wheel track is the distance between the center planes of the rear wheels.

In general, the wider the wheelbase is, the higher the driving comfort is. If the front wheel is too wide, the steering wheel will be very heavy, which affects the driving comfort. In addition, the track distance also has an influence on the total width, total weight, lateral stability and safety of the car.

The greater the track distance, the more favorable the smoothness of the operation, and also the favorable shape of the body and the spaciousness of the carriage, the better the lateral stability. However, since the track width is wide, the total width and total weight of the automobile are also generally increased, and the problem of sluging to the side of the vehicle body is apt to occur. If the track width is too wide, it will affect the safety of the car. Therefore, the track distance should be compatible with the width of the car body.
