Abstract

The invention relates to an RWD automobile gearbox transmission error detection test bench and a comprehensive testing method, and belongs to the technical field of automobile gearbox detection. The test bench comprises a test bench device and an adjustment and supporting device. The test bench device comprises an AC drive motor, an input end elastic shaft coupler, an input end transmission error comprehensive detection device, an input end cv-joint synchronous universal shaft coupler, a gearbox input spline shaft, a tested gearbox, a gearbox output flange shaft, a first output end elastic shaft coupler, an output end transmission error comprehensive detection device, a second output end elastic shaft coupler, a two-gear reduction gearbox, an output end cv-joint synchronous universal shaft coupler, and an AC loading motor. The test bench is advantageous in that the device employs a U-shaped layout and reduces the area of an occupied land; the test bench can measure the static and dynamic transmission errors of the gearbox at the same time; the test bench employs the two-gear reduction gearbox and a sliding table mechanism, can meet the testing requirements of different types of gearboxes, and improves the universality of the test bench.

Description

technical field [0001] The invention relates to the technical field of automobile gearbox detection, in particular to a testing platform and a testing method for transmission error detection of rear-drive automobile gearboxes. Background technique [0002] There are two main drive forms for the application of mechanical gearboxes in minibuses: one is front-front drive, and the other is front-rear drive. Among them, in front-wheel-drive vehicles, the engine is placed horizontally, and the mechanical gearbox matched with it generally integrates a differential and a final drive. The power output by the gearbox assembly is directly transmitted to the front wheels through the half shaft to drive the vehicle. Driving; in a front-rear drive vehicle, the engine is generally placed vertically, and the gearbox does not integrate a differential and a final drive, but the power of the output shaft is transmitted to the rear axle through a drive shaft, and then through the differential, ...
