摘　　要：通过搭建湿式制动器惯性试验台架,在相同油品及摩擦材料的前提下,研究湿式制动器制动初速度、制动压力和油温对制动力矩的影响。结果表明,在一定的制动压力、温度和初速度范围内,制动力矩与制动压力呈线性关系,制动压力是制动力矩的关键影响因素之一,但单位制动压力产生的制动力矩随着制动压力的升高有下降趋势,可用制动力矩线性度作为评价指标;随着制动初速度的升高,制动力矩呈下降趋势,可用速度力矩稳定系数作为评价指标;随着油温的升高,制动力矩呈衰减趋势,可用热衰退率作为评价指标。The influence of the initial braking speed, braking pressure and oil temperature on the braking torque of wet brake was studied by building the inertial test bench of wet brake under the premise of the same oil and friction material. The results show that within a certain range of brake pressure, temperature and initial speed, the braking torque and braking pressure are linear, and the braking pressure is one of the key critical factors affecting the braking torque, but the braking torque generated by unit braking pressure decreases with the increase of braking pressure.
