Problems solved by technology

Although these patents have solved the problem of integrating the in-wheel motor system and the chassis, the in-wheel motor occupies most of the space in the wheel, the degree of freedom in suspension layout is low, and the performance of the chassis is poor. The wheel hub motor is difficult to generalize

Abstract

The invention discloses an automobile chassis integrated with a hub motor drive device. The automobile chassis comprises a front wheel drive assembly and a rear wheel drive assembly, wherein the front wheel drive assembly consists of a hub motor with a parallel-axis type speed reducer, a MacPherson type front suspension, a brake system, a steering system and the like; and the rear wheel drive assembly consists of a hub motor with a parallel-axis type speed reducer, a torsion beam type non-independent rear suspension, a brake system, a steering system and the like. According to the automobile chassis disclosed by the invention, the parallel-axis type hub motor is integrated with the MacPherson type front suspension, a motor of an eccentric-axis structure can avoid the optimal arrangement position of each hard point of the chassis, especially can guarantee a design state that offset distance of a front wheel main pin is 0, so that chassis performances when a vehicle drives, brakes and steers are improved. A rear wheel adopts the hub motor which is the same as that of the front wheel, and can carry the torsion beam suspension, so that pitching characteristics when the vehicle starts and brakes can be inhibited; and meanwhile, a motor control function is combined, and side inclining when the vehicle steers further can be inhibited.

Description

technical field [0001] The invention relates to an automobile chassis integrating a hub motor driving device, belonging to the technical field of new energy automobile hub motors. Background technique [0002] Traditional electric vehicles are mainly driven by centralized motors, replacing traditional engines with motors, and still retaining transmission mechanisms such as reducers and drive shafts. The hub motor electric vehicle uses the motor to directly drive the wheels, which can realize four-wheel independent control, four-wheel steering, torque vector control and other functions, and the hub motor electric vehicle saves the transmission mechanism, which greatly improves the work efficiency. It can be seen from the above Compared with traditional cars, electric vehicles with in-wheel motors have obvious advantages, and have become the development direction of the next generation of electric vehicles. [0003] Aiming at this technical field, major automobile companies a...
