Abstract

The invention relates to the field of cars, in particular to a gear supporting structure, a hub motor drive system and a hub motor drive axle. The gear supporting structure comprises a front end cover (24) of a drive motor assembly (2) and a gear rack (20), wherein the front end cover is provided with first supporting holes (241); the gear rack is provided with second supporting holes (201); the gear rack (20) is arranged on the front end cover; the gear rack and the front end cover jointly form an accommodating space (25); first supporting holes and the second supporting holes are in one-to-one correspondence; the corresponding first supporting holes and the second supporting holes are once processed and molded; the accommodating space is positioned between the first supporting holes and the second supporting holes. The hub motor drive system comprises the gear supporting structure. The hub motor drive axle comprises the hub motor drive system according to the claims. The coaxiality of two bearing bases for mounting a gear can be guaranteed by the gear supporting structure, the hub motor drive system and the hub motor drive axle.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a gear support structure, a wheel-side motor drive system and a wheel-side motor drive axle. Background technique [0002] Currently, the gears need to be supported by two separate bearing housings, which are machined on the front end cover and another component in the drive motor assembly. Therefore, during the installation process, it is difficult to ensure the coaxiality of the two bearing housings. SUMMARY OF THE INVENTION [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a gear support structure, a wheel-side motor drive system and a wheel-side motor drive bridge that can ensure the coaxiality of two bearing seats. [0005] (2) Technical solutions [0006] In order to solve the above technical problem, one aspect of the present invention provides a gear support structure, comprising: a front end cov...
