The pitch is the distance between the center lines of the tracks left by the wheels on the ground.
If the ends of the axle are double wheels, the wheelpitch is the distance between the two central planes of the double wheels.
Generally speaking, the wider the wheel base, the higher the driving comfort.
The car’s wheelbase has the front wheelbase and the back wheelbase. The front wheelbase is the front wheelbase of the front two wheels, and the back wheelbase is the distance between the center plane of the back two wheels. The two can be the same or different.
The use of different wheel spacing is to adjust the driving characteristics of the vehicle.
Because of the differences between the distribution of the center of gravity and the design of the suspension, different vehicles will exhibit different driving characteristics.
Some cars tend to oversteer, while others tend to understeer.
Congenital oversteer can be corrected if the rear wheelbase is greater than the front wheelbase, as the rear axle with a larger wheelbase provides greater lateral support and delays the appearance of tail slings.
