Abstract

The invention provides a testing device for a coaxial electric drive axle gearbox. A motor rotor shaft of a coaxial electric drive axle is modified, a hollow rotor shaft is adopted, and a conveying device with a hollow output rotating shaft is used in the testing device, so that the input motor and the load motor can be positioned on different axes, and the mechanical interference between the input motor and the load motor is avoided; and the performance of the coaxial electric drive axle gearbox can be 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...
