In the braking process, the wheel lock when the maximum deceleration of braking. right?
First, there is no deceleration of the said, only the acceleration, but the brake is negative acceleration (refer to high school physics compulsory 1) theoretically said that the maximum acceleration when locked, but not necessarily, depending on the friction factors, ground friction. Tire surface friction index, the vehicle traction may be, but now the vehicle will have anti-lock friends
Brake braking force and the ground can provide the maximum value of the same adhesion, even if the brakes continue to increase the braking force, the ground can not provide the appropriate reaction to balance, this time is the wheel lock state, hold Dead state between the wheel and the ground is pure sliding friction, rather than completely locked in the rolling state of the friction is static friction, high school physical knowledge can be seen, sliding friction is less than the maximum critical static friction value.
Brake is definitely not the maximum wheel brake deceleration when braking.
