摘　　要：介绍了液力缓速器的结构和工作原理,以某款商用车匹配采埃孚液力缓速器为例,详细阐述了商用车匹配缓速器时的空间布置、控制策略、冷却回路等设计内容。通过实车转鼓试验研究缓速器的制动性能。结果表明:整车匹配液力缓速器时,适当增大整车散热功率,能保证液力缓速器稳定的持续制动性能。First,the structure and working principle of hydraulic retarder were introduced.Then,taking commercial vehicle matching with ZF hydrodynamic retarder as an example,3D-layout,control strategy and cooling circuit were expounded.Finally,braking performance of hydrodynamic retarder was studied on chassis dynamometer.The results show that when heavy vehicle is matched with hydrodynamic retarder,it is necessary to increase radiator power to ensure the stable continuous braking performance of hydrodynamic retarder.
