Problems solved by technology

[0003] At present, the structure of most vehicle drive systems (especially the drive system of new energy vehicles) is that the central motor is connected to a traditional rear axle through the transmission shaft. The floor layout needs to achieve drive anti-skid control and body stability control through braking, and the wheel motor drive axle has become an important research direction at home and abroad. This drive axle generally includes drive m

Abstract

The invention relates to a wheel side motor driving system and a wheel side motor driving axle. The wheel side motor driving system comprises a main speed reducer assembly (4), a wheel side speed reducer assembly (6) and a hub assembly (5). The main speed reducer assembly comprises an output gear (16); the wheel side speed reducer assembly comprises a sun wheel shaft (12), a planet wheel (18), a wheel reduction shell (22) and a planet frame (31); the output gear of the main speed reducer assembly is connected with the sun wheel shaft in a power transmission manner, and the sun wheel shaft is meshed with the planet wheel; the planet wheel is arranged on the planet frame in a power transmission manner, and the planet frame is arranged in the wheel reduction shell in a power transmission manner; the wheel reduction shell is connected with the hub assembly in a power transmission manner; and the wheel side motor driving axle comprises the wheel side motor driving system. Compared with the prior art, the wheel side motor driving system and the wheel side motor driving axle have the advantage that rim space is effectively utilized, and the speed ratio is increased.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a wheel-side motor drive system and a wheel-side motor drive axle. Background technique [0002] With the gradual withering of oil resources and the gradual increase of air pollution, the society is increasingly calling for new energy vehicles, including pure electric, hybrid, plug-in, fuel cell and other forms of vehicles. New energy vehicles greatly reduce the impact on Oil dependence and air pollution. Compared with traditional internal combustion engine vehicles, new energy vehicles have undergone tremendous changes in both the general layout of the vehicle and the drive system assembly due to the different forms of energy supply. The drive system assembly is crucial to the vehicle. Important, it not only undertakes the carrying function and driving function, but also directly determines the safety and comfort performance of the vehicle. [0003] At present, the structure of most...
