CSU1020A货车总体设计及前制动器设计CSU1020A货车总体设计及前制动器设计摘要汽车制动系的功用是使汽车以适当的减速度降速行驶直至停车，在下坡行驶时使汽车保持适当的稳定车速，使汽车可靠地停在原地或坡道上。制动系应至少包括行车和驻车制动装置，有足够的制动效能，工作可靠，任何速度下制动都不应丧失操纵性和方向稳定性。领从蹄制动器发展较早，其效能及效能稳定性均居于中游，且有结构较简单等优点，故目前仍相当广泛地用于各种汽车，故本设计采用较常用的鼓式领从蹄式制动器。通过合理设计汽车的总体尺寸、选择合适的发动机型号以及合适的制动器参数，合理分配前后制动器的制动力矩，并进行校核，从而保证汽车有良好的制动性能，并且保证此货车在制动时又能保持良好的汽车方向稳定性和操纵稳定性。关键词：制动系；领从蹄式制动器；货车设计个CSU1020A货车总体设计及前制动器设计目录1．总体设计······························································································11.1轴数、驱动形式、布置形式·································································11.1.1轴数选择·················································································11.1.2驱动形式的选择：4×2·································································11.1.3布置形式的选择········································································11.2汽车主要参数设计·············································································31.2.1主要尺寸·················································································31.2.2进行汽车轴荷分配·····································································41.3发动机功率、转速、扭矩及发动机型号的确定·········································41.4汽车轮胎的选择················································································51.5确定传动系最小传动比，即主减速器传动比············································61.6确定传动系最大传动比，从而计算出变速器最大传动比····························62、前轴制动器设计·····················································································82.1制动系统的结构形式··········································································82.1.1制动管路分路系统形式·······························································82.1.2制动驱动机构的形式··································································82.1.3制动器的结构形式...
