汽车制动器楔块式张开装置的性能分析

Performance Analysis of the Wedge-type Expanding Unit of Automobile Brake

对汽车制动器楔块式张开装置中的制动楔角、行程与制动间隙的关系和蹄端制动力的分配问题进行了较深入地分析和探讨。

The paper analyses the relations among the brake wedge angle, the stroke and the brake clearance of the wedge-type expanding unit of automobile brake and studies the brake force allocation at the shoe end. The computing formulae of the force transmission ratio of the unit and the expanding force at the shoe end are derived.
