Problems solved by technology

However, the equal-length double trailing arms also have the adverse effect of their jumping: that is, the wheelbase changes greatly with the wheel jumping during the jumping, which will lead to serious tire wear and other phenomena.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the present invention provides a wheel side electric drive system for unequal length double trailing arm suspension, comprising a motor 1, a driving gear 2, a bearing support 3, a small bearing 4, a drive shaft 5, a large bearing 6, a lower longitudinal Arm 7, column 8, driven gear 9, upper trailing arm 10 and vehicle frame 11.

[0026] figure 1 It is a schematic diagram of the structure of the present invention. The deceleration and torque increasing device of the present invention can adopt synchronous belt transmission, chain transmission or gear transmission. Here, the gear transmission will be used as an example for illustration. The driving gear 2 is installed and supported in the bearing support 3 through the small bearing 4, the bearing support 3 and the motor 1 are installed and fixed on the vehicle frame, and the center lin...

Abstract

The invention discloses an unequal-length double-trailing-arm suspension wheel side electric driving system. A driving wheel is arranged in a bearing supporting base through a small bearing in a supporting mode. A motor and a bearing supporting base are integrally arranged and are fixed on a vehicle frame. Power is transmitted between the driving wheel and a driven wheel in a synchronous-belt-transmission mode or a chain-transmission mode or a gear transmission mode, the driven wheel is connected with a driving shaft through a spline for power transmission, the driving shaft is supported in a stand column through a large bearing, and an integrated mechanism assembled by the driven wheel and a double-trailing-arm suspension swings around the hinged axis of double trailing arms and the vehicle frame along with the double trailing arms. The system has the advantages that a half axle and a cardan joint in a traditional electric vehicle driving vehicle device are removed, non-sprung mass is effectively reduced, and vehicle smoothness and vehicle wheel ground contacting performance are improved.

Description

technical field [0001] The invention belongs to the field of electric vehicle chassis and transmission, and in particular relates to an electric drive system for wheels with unequal-length double trailing arm suspensions. Background technique [0002] With the continuous rise of electric vehicles, a variety of driving forms of electric vehicles have emerged. The size of the car's unsprung mass directly affects the ride comfort and wheel grounding of the car. At present, the wheel-side electric drive system represented by electric wheels has a simple drive system and vehicle structure, large available space, and high transmission efficiency. The torque of each drive wheel can be independently controlled, which is conducive to improving driving performance under harsh road conditions. performance has become a research hotspot. However, since the motor is installed in the driving wheel, the unsprung mass of the car is relatively large, which is not conducive to the smoothness...
