Abstract

The present invention relates to the technical field of transmissions, and provides a transmission shift performance testing system and a testing method. The transmission shift performance testing system includes an input motor, a first output motor, a second output motor, a transmission control unit, a real-time controller and The upper computer, the real-time controller is the control core of the entire transmission shift performance test system, the input motor, the first output motor and the second output motor simulate the vehicle driving conditions of the transmission, the transmission control unit controls the transmission to complete the shift control, and Carry out secondary calculation according to the speed signal of the transmission to obtain the shifting performance parameters of the transmission, and then pass the obtained shifting performance parameters to the host computer; the host computer judges whether the current transmission to be tested is qualified according to the generated shifting performance parameters, and realizes For the qualification test of the transmission, the structure is simple, and the test efficiency and test accuracy are high.

Description

technical field [0001] The invention belongs to the technical field of transmissions, and in particular relates to a transmission shift performance testing system and testing method. Background technique [0002] The shifting performance of a hydraulic automatic transmission is an important indicator of the transmission's qualified performance. It can not only measure the mechanical, hydraulic and electrical performance of the transmission, but also truly and directly reflect the shifting quality of the transmission on the vehicle. Therefore, each transmission needs to be tested for various performances when the terminal is offline. [0003] At present, there are various testing methods for the transmission, but the existing testing methods have complex testing process, low testing efficiency, and low testing accuracy. Contents of the invention [0004] The purpose of the present invention is to provide a transmission shifting performance testing system with simple testin...
