摘　　要：针对商用车缓速行驶中湿式制动器散热能力不足问题,提出一种湿式制动器冷却油可循环式方法,并运用有限元分析软件ANSYS Workbench和流体分析软件Fluent进行仿真计算。结果表明,采用冷却油可循环式方法可以提高散热能力,能够满足商用车缓速行驶散热要求,且散热油槽越长、冷却油流量越大散热效果越好,比普通冷却油不循环式湿式制动器散热能力提高了2~3倍。Aiming at the problem of insufficient heat dissipation ability of wet brakes during slow-speed driving of commercial vehicles,a local method of circulating wet brake cooling oil was proposed,and the simulation calculation was performed by using finite element analysis software ANSYS Workbench and fluid analysis software Fluent.The results show that the cooling oil recirculation method could improve the heat dissipation capacity,and could meet the requirements for slow-moving heat dissipation of commercial vehicles.The heat dissipation capacity of the brake was increased by 2~3 times.
