The distance between the centerline of the trajectory left by the wheel on the vehicle support plane (generally the ground).
In general, the wider the wheelbase, the higher the driving comfort, but some home-made cars do not have directional assistance. If the front wheels are too wide, their steering wheel will be "heavy," affecting driving comfort.
In addition, the track distance also has an influence on the total width, total weight, lateral stability and safety of the car.
Features
In general, the larger 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.
Front trackThe car's track has a front track and a rear track, and the front track is the distance between the center plane of the front wheels.
When both ends are single wheels, the track distance
Rear trackThe rear track is the distance between the center planes of the two rear wheels. The two wheels can be the same or different. If the ends of the axle are double wheels, the wheelbase is the distance between the two center planes of the two wheels.
When both ends are double wheels
