Truck Encyclopedia What is wheelbase

The wheelbase is the distance between two perpendicular lines perpendicular to the longitudinal plane of the vehicle, passing through the midpoint of two adjacent wheels on the same side of the vehicle. In short, the distance from the center of the front axle to the center of the rear axle. For a vehicle with three or more axles, the total wheelbase is the sum of the wheelbases, which are represented by the wheelbases between the two adjacent wheels from front to rear.

Before we talk about wheelbase, let's first understand the length of this parameter. As we all know, car length generally refers to the car from the front to the end of the length, it is the car's use, function, ease of use and other parameters of the greatest impact. It is obvious that a long car body means a large longitudinal usable space, but a long car body makes it difficult to turn around and stop.

After the length of the car is determined, the wheelbase is the most important factor affecting the ride space, because the vast majority of hatchbacks and hatchbacks, the passenger seats are arranged between the front and rear axles. Wheelbase refers to the distance between the front and rear axles, and many old car friends also think of wheelbase is similar to the distance between the front and rear axles. The long wheelbase makes the longitudinal space of the occupant increase, and the direct benefit is the leg space which has a great influence on the ride comfort. In the aspect of driving performance, the long wheelbase can improve the stability of straight cruise, but the steering flexibility decreases and the turning radius increases. It was therefore necessary to strike the right balance between stability and flexibility.
