摘　　要：介绍了国内车用液力缓速器的研究现状,分析了液力缓速器内流场液流的运动特性及研究方法,同时分析了结构参数和散热性能等相关因素对液力缓速器制动转矩的影响,分析了电控系统及其控制方法,展望了液力缓速器的发展方向,旨在为高速、重载车用液力缓速器的研究提供相应的理论借鉴。The research status of the basic theories of the hydraulic retarder is analyzed, and the impacted factors of the retarding torque produced by structural parameters, thermal performance, and other impact factors of hydraulic retarder are investigated in this paper. The hydraulic retarder electric control system and its control mode are also analyzed ; and then the future research work about the hydraulic is discussed. A theoretical significance for hydraulic retarder of high speed and heavy load vehicle having a safe and reliable retardation ability is provided.
