Abstract

The invention provides an overrunning clutch reliability test method and a test bed, and belongs to the test method of a clutch. The method comprises the following steps of: constructing a speed changing box assembly performance test bed, wherein a power source and loading equipment adopt alternating-current variable frequency motors, and the rotating speed and the rotating torque of each of the alternating-current variable frequency motors can be regulated; detecting the transmission efficiency of a speed changing box assembly; and drawing a relation curve between the transmission efficiency and the output rotating speed of the speed changing box according to a test result, wherein a phase change point in the curve represents working states of separation and combination of the overrunning clutch. Seven components of the special test bed, namely a power alternating-current motor, an input rotating torque and rotating speed sensor, a transmission shaft, a speed changing box torque converter assembly, an output rotating torque and rotating speed sensor, a six-gear transmission box and a loading alternating-current motor are connected in sequence. The overrunning clutch reliability test method and the test bed have the advantages of truly representing the working condition of the overrunning clutch and facilitating the speed changing box performance test and the overrunning clutch reliability index test.

Description

technical field [0001] The invention relates to a test method for a clutch, in particular to a reliability test method and a test stand for an overrunning clutch. Background technique [0002] The overrunning clutch is an important part of the twin-turbine torque converter assembly, which can automatically adjust the working conditions of the first and second turbines of the twin-turbine hydraulic torque converter according to the loader's working conditions. With the market demand, the tonnage of the loader is gradually increasing, and the reliability requirements for the overrunning clutch are also increased. Therefore, the reliability performance of the overrunning clutch is also one of the important evaluation indicators for the comprehensive performance of the gearbox assembly. [0003] At present, overrunning clutch manufacturers are generally equipped with special overrunning clutch performance and reliability test benches, but when the overrunning clutch and gearbox ...
