| Abstract: | Bi-directional-servo drum brakes has been used on off-road trucks and light trucks commonly as central parking brake because of its high efficiency factor. Several designing points of the development for bi- directional-servo parking brake have been detailed in this paper, it analyzing the calculation methods of efficient factor for bi-directional-servo parking brake and having been proved the correctness through comparing between theoretical calculations value and test value, analyzing the method of choosing value for friction coefficient and also researching how to designing and controlling brake clearance. |
