Test device and test method of duration of direction and shift changing clutch of gearbox

Abstract

The invention provides a test device and test method of duration of a direction and shift changing clutch of a gearbox. A slotted type test bench device is adopted. The test device comprises an inputmotor, a test gearbox, a rotational inertia disc, an input rotation speed sensor and an output rotation speed sensor. The input motor, the test gearbox and the rotational inertia disc are connected with each other through a transmission shaft. The input rotation speed sensor is arranged on the output end of the input motor. The output rotation speed sensor is arranged on the output end of the testgearbox. The input rotation speed sensor and the output rotation speed sensor acquire speed signals in real time and transmit the speed signals to an industrial personal computer. Through the industrial personal computer, increasing and decreasing of the rotation speed of the input motor are achieved. Based on actual use conditions, reliability of the test is improved and automatic operation is achieved. The device is simple and reliable, there is no need to independently test parts like frictional sheets and clusters and test cost is reduced.

Description

technical field [0001] The invention relates to a reversing gear clutch durability test device and test method applied to a loader gearbox. The method is based on the gearbox assembly, and can realize automatic control and testing of the reversing gear clutch durability test during the prototype test process. Accelerated durability test. Background technique [0002] As the construction machinery of construction machinery, the loader mainly works in mines and construction sites where the environment is relatively harsh. There are many forward and backward reciprocating conditions, and the working hours are long. As the core component of the loader, the gearbox is mainly used to realize the forward and backward shoveling and walking of the vehicle. The forward and reverse clutches control the forward and reverse gears of the gearbox respectively. The shifting process is a process of combining and disengaging the two respectively. Therefore, the life of the reversing gear clu...
