Why the driving force of the car is greater than the wheel adhesion will appear slip phenomenon
This is a conceptual problem, the drive torque is generated by the engine, the axle to the axle rotation of the wheel drive the concept of the concept you understand it, the ground on the wheel force is generated by passive, that is, the wheel rotation due to friction on the ground Of the reaction force, to promote the wheels and the vehicle forward, the ground reaction force and the direction of the same line
The wheel of the adhesion is the maximum friction between the wheel and the ground The driving force of the car actually the engine reaches the drive shaft torque through the wheel and the ground contact point into force, the wheel rotation force is large enough, not slip, then the ground Friction force reaction to the wheel, to promote the overall image of the car as before, the friction coefficient is not enough, it can only slip hot smoke this to the brake brake to consider a reason to reverse, think of bicycle brake slip
