Abstract:

Firstly,according to the working principles of the braking unit RZS,the kinematic diagram was built up.Then,the DOF of RZS with and without the brake disc was analyzed and compared.The braking rate and its change rules were  calculated and analyzed respectively  under two conditions:the pad clearance was equal to the setting value and  another the pad clearance was reset after braking operation. It is found that:the braking rate of RZS meets the design requirements and there is a linear relationship between the increment of the self-adjustment mechanism and the amount of the pad's 　wear.During the entire service life of the pad, the braking rate of RZS barely changes.

Key words: disk brake unit, braking rate, pad clearance, self-adjustment mechanism, wear
