What is wheel retardation? What is its practical significance?
Wheel block force on the vehicle's power, economy has a significant impact, the wheel block force refers to the driving and parking brake is fully released state, the transmission is in neutral, the brake test bed to drive the wheel required role Force, check the wheel block force is to understand whether the brake is dragged, the wheel block force depends on the size of the hub assembly, brake assembly, axle assembly maintenance, only these parts of the adjustment, lubrication and other maintenance operations Effectively reduce the wheel block force
Stiffness means that the driving force and the parking brake are in the fully released state, the speed of the four-position position, the test, the test bench to drive the wheel required force. The wheel force of the wheel shall not be greater than 5% of the shaft load. If too large, for many reasons, the first bearing to add enough oil, then have to check the brake parts, such as the brake line, brake arm, the car up, hand to turn the wheel, should be flexible, but To brake to live, brake death! Only the best.
