What Is The Track Width Of A Vehicle

Wheelbase refers to the distance between the centerline of the trajectory left by the wheels on the vehicle's support plane (usually the ground). If the two ends of the axle are double wheels, the wheelbase is the distance between the two central planes of the double wheels. Generally speaking, the wider the wheelbase, the higher the driving comfort.
Generally speaking, the wider the wheelbase, the higher the driving comfort, and a wider wheelbase can provide better stability. When the vehicle is tilted horizontally, the outer wheels can provide better support. In curves, the vehicle's roll angle is smaller, and the limit of the outer wheels will also appear later. In addition, the track width also has an impact on the overall width, weight, and safety of the car.
An increase in front wheel distance will increase the turning radius of the vehicle, so for vehicles with large front wheel distance, the front wheel steering angle should also be correspondingly increased to offset the adverse impact on the turning radius. Generally speaking, the larger the wheelbase, the more favorable it is for handling smoothness, as well as for the body shape and cabin spaciousness, resulting in better lateral stability. But with a wider wheelbase, the overall width and weight of the car generally increase, and it is prone to the problem of throwing mud towards the side of the body. If the wheelbase is too wide, it can also affect the safety of the car, so the wheelbase should be adapted to the width of the vehicle body.
The track width of a car can be divided into front track width and rear track width. The front track width is the front track width of the front two wheel centers, and the rear track width is the distance between the center planes of the rear two wheels. The two can be the same or different. The use of different track widths before and after is to adjust the driving characteristics of the vehicle. Due to differences in center of gravity distribution and suspension design, different vehicles may exhibit different driving characteristics. Some cars have a tendency to oversteer, while others are prone to understeer. The fact that the rear track width is greater than the front track width can correct the congenital oversteer of the vehicle, as the rear axle with a large track width can provide greater lateral support and delay the occurrence of tailspin. Similarly, having a front track width greater than the rear track width can help improve the inherent tendency of vehicles to understeer.
