Abstract

The present application provides a test device for a coaxial electric drive axle gearbox. By modifying the motor rotor shaft of the coaxial electric drive axle, using a hollow rotor shaft, and using a transmission device with a hollow output rotating shaft in the test device, the input motor can be on a different axis from the load motor, In this way, the mechanical interference between the input motor and the load motor is avoided, and the performance of the coaxial electric drive axle gearbox is effectively tested.

Description

technical field [0001] The application relates to the field of automobile performance testing, in particular to a testing device for a coaxial electric drive axle gearbox. Background technique [0002] In recent years, with the development of new energy vehicle technology routes, two-in-one or three-in-one electric drive axles have been used more and more. [0003] Testing the gearbox of the electric drive axle is a very important part of vehicle performance testing. However, due to the deep integration of the motor and gearbox of the two-in-one or three-in-one electric drive axle, the gearbox of the electric drive axle is tested separately It has become a technical difficulty, especially the loading test of the coaxial electric drive assembly axle gearbox is particularly difficult. At present, no effective testing solution has been found in the industry. [0004] Therefore, it is of great significance to design a test device suitable for coaxial electric drive axle gearbox...
