Problems solved by technology

Therefore, the unsprung mass is relatively large, and it is difficult to meet the requirements of vehicle ride comfort
At the same time, the additional damping device will increase the degree of freedom of the internal structure of the wheel, which will cause changes in the wheel parameters during the driving of the vehicle.

Abstract

The invention provides a power transmission integrated electric wheel. The power transmission integrated electric wheel comprises an outer rotor hub motor (1), a planetary reduction gear, a reducer shell body, an elastic component (36), a steering stand column (7), a disc brake and a vehicle wheel; and power is generated through the outer rotor hub motor (1), the power is input into the planetary reduction gear through a sun wheel (27) connected with the outer rotor hub motor (1), a gear ring (16) maintains a braking state, the power is output to a rim (10) through planetary wheels (26) and a first planetary carrier (19), and drives the vehicle wheel. The elastic component (36) is arranged between the shell body (11) and the steering stand column (7) and used for shock adsorption treatment on the outer rotor hub motor (1) and the planetary reduction gear integrally; and a matching surface is designed between the shell body (11) and the steering stand column (7), and the degree of freedom of the motion of the outer rotor hub motor (1) and the planetary reduction gear is limited to the vertical direction. The power transmission integrated electric wheel is high in integration degree and good in shock absorption effect, and shock absorption of the integrated electric wheel is achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle power transmission, and in particular relates to a wheel assembly including a hub motor. Background technique [0002] In the field of vehicle power transmission, distributed drive is an important technology development direction. At present, there are mainly two structural forms of distributed drives: wheel-side motor structure and hub motor structure. Compared with the wheel motor, the hub motor has a higher degree of integration, a shorter drive chain, and higher efficiency. However, it will have a larger unsprung mass, which has a certain impact on the ride comfort of the vehicle. It needs to be passed Some adjustments are made to the suspension design parameters to compensate. At the same time, the hub motor cancels the universal transmission mechanism, which makes the layout of the chassis and suspension more free, and also makes the distribution of power more accurate and free, which can ...
