Problems solved by technology

However, in the prior art, the design that can realize the separation of the wheel motor and the hub to reduce the unsprung mass will make the installation of the reduction gear and the distribution of the mass not well unified, and most of them can only be used as the rear drive wheel. It is difficult to realize the turning

Abstract

The invention discloses an unequal-length double-wishbone suspension wheel-side drive system for reducing unsprung mass integrally, comprising an unequal-length double-wishbone suspension, a drive integration device, a universal joint transmission shaft, and the like. The drive integrated device is fixed on the frame, which includes a drive motor and a planetary gear reducer. The integrated drive device and the wheel drive shaft realize power transmission of unequal heights but coaxial lines through the universal joint drive shaft, which can be accepted to a certain extent. The misalignment of the integrated drive unit and the wheel axle caused by jumping on uneven roads. When the car is turning, the independent work of the drive system and the steering system can be achieved by controlling the speed of the motor and the steering rod. The design not only greatly reduces the unsprung mass and improves the ride comfort and stability of the vehicle, but also can use the traditional steering method to achieve a certain angle of steering.

Description

technical field [0001] The invention belongs to the field of chassis and transmission in electric vehicles, and in particular relates to a highly integrated double-wishbone suspension wheel side drive system with unequal lengths to reduce larger unsprung mass. Background technique [0002] Today, with the continuous development of electric vehicles, a variety of driving forms have emerged to meet different needs. At present, the wheel-side driving method represented by electric wheels is simple in structure, high in transmission efficiency, and free in space utilization. The torque can be independently controlled, and comprehensively improving the driving performance and comfort under various road conditions has become the development focus of various research institutes and companies. However, in the traditional wheel drive system, the drive motor is placed near or inside the wheel hub to form an integrated unsprung mass, which greatly increases the unsprung mass, which is ...
