Abstract

The invention relates to a testing stand for testing the transmission error of a mechanical gearbox of a front drive automobile and a comprehensive testing method, and belongs to the technical field of automobile gearbox test. The testing stand comprises a driving motor, an input shaft resilient coupler, a comprehensive input shaft transmission error detection device, an input shaft cage-type synchronous universal shaft coupler, a gearbox input spline shaft, a certain type gearbox, a first output shaft resilient coupler, a comprehensive first output shaft transmission error detection device, an arc tooth synchronous belt drive input shaft resilient coupler, an arc tooth synchronous belt transmission device, an arc tooth synchronous belt transmission output shaft resilient coupler, a first loading motor, a second output shaft cage type synchronous universal shaft coupler, a comprehensive second output shaft transmission error detection device, a second output shaft resilient coupler and a second loading motor. The testing stand is novel in structure, the first loading motor is arranged in a bias manner, the occupied space is small, and static and dynamic transmission errors of a gearbox can be measured. The testing stand has high universality.

Description

technical field [0001] The invention relates to the technical field of automobile gearbox testing, in particular to an automobile gearbox transmission error detection test bench and a testing method. Background technique [0002] Front-wheel-drive cars refer to cars driven by the front wheels. The gearbox of a front-wheel-drive car is usually integrated with the drive axle. The operating mechanism is simple, the engine heat dissipation conditions are good, and the interior space is large. At present, most medium and small cars use this structure. The gearbox is a key component of power conversion in the automotive transmission system, and the performance of the gearbox largely determines the performance of the vehicle. The transmission error of the gearbox is an important factor affecting the performance of the gearbox. The transmission error is one of the main reasons for the vibration and noise of the gearbox. It includes many contents such as the dynamic performance and s...
