Abstract

The invention relates to the technical field of transmission, and provides a transmission shift performance test system and test method. The transmission shift performance test system comprises an input motor, a first output motor, a second output motor, a transmission control unit, a real-time controller and an upper computer. The real-time controller acts as the control core of the whole transmission shift performance test system. The input motor, the first output motor and the second output motor simulate the vehicle driving condition of the transmission. The transmission control unit controls the transmission to complete shift control and performs secondary calculation according to the rotating speed signal of the transmission so as to obtain the shift performance parameters of the transmission. Then the obtained shift performance parameters are transmitted to the upper computer. The upper computer judges the qualified state of the current transmission to be tested according to the generated shift performance parameters so as to realize qualification testing of the transmission. The transmission shift performance test system is simple in structure and high in test efficiency and test accuracy.

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...
