Abstract

The invention discloses a high-performance mechanical coupling test system and method for electric drive axle power assemblies. The first power output end of the first electric drive axle power assembly is in transmission connection with one transmission device; the second power output end of the first electric drive axle power assembly is in transmission connection with the other transmission device; the first power output end of the second electric drive axle power assembly is in transmission connection with one transmission device; the second power output end of the second electric drive axle power assembly is in transmission connection with the other transmission device; and the high-performance mechanical coupling test system further comprises a first variable frequency control motorand a second variable frequency control motor. The test environments of the electric drive axle power assemblies under various different driving conditions can be simulated according to different compensation schemes, so that the relatively complete comprehensive performance evaluation of the electric drive axle power assemblies is realized.

Description

technical field [0001] The invention belongs to the testing technology of an automobile drive axle assembly, and in particular relates to a high-performance towing test system and a testing method for an electric drive axle power assembly. Background technique [0002] Those skilled in the art know that the differential of the automobile drive axle power assembly can make the (front and / or rear) drive wheels in the left and right directions rotate at different speeds. , two planetary gears and a planet carrier. The main function of the differential is to ensure that the left and right wheels roll at different speeds when the car is turning, on uneven roads or in extreme road conditions, and to ensure the safety of the car by adjusting the speed difference between the left and right wheels. The drive axle powertrain is the core component of the vehicle drive system, and it is also one of the most concerned components of most automobile companies. The performance index of the...
