Problems solved by technology

[0003] However, in the general wheel drive system, due to the introduction of drive motors, reducers and other components in the wheel / wheel, the unsprung mass of the vehicle is significantly increased, which directly affects the grounding of the wheel and the ride comfort of the vehicle body.
[0004] Patent 201110053093.0 mentions a structure and method for reducing the equivalent unsprung mass of the single-wishbone suspension wheel side electric drive system, but it is only applicable to non-steering wheels

Embodiment Construction

[0028] Attached below figure 1 The present invention is further described.

[0029] Such as figure 1 As shown, the present invention provides a MacPherson suspension wheel side electric drive system for steering wheels, including a vibration isolation block assembly 1 with bearings, a vehicle frame 2, a shock absorber 3, a reduction box 4, a first One rotating hinge 5, motor 6, elastic hinge 7, lower swing arm connecting rod 8, steering knuckle connecting rod 9, second rotating hinge 10, universal joint 11, half shaft 12, hub 13, hub bearing 14, third rotating hinge 15. Steering knuckle 16, ball joint 17; among them,

[0030] The casing of the motor 6 is fixedly connected with the casing of the reduction box 4, and is supported on the frame 2 by two elastic hinges 7 (only one is shown in the figure), and the connecting line of the hinge points of the two elastic hinges 7 constitutes the lower swing arm The hinged swing axis with the frame 2 thus functions as the lower arm o...

Abstract

The invention discloses a Macpherson suspension wheel rim electric driving system for a steering wheel. A motor casing is fixedly connected with a gearbox casing and is supported on a support through an elastic hinge; one end of a lower swing arm connecting rod is connected with the gearbox casing through a first rotating hinge; one end of a steering knuckle connecting rod is connected with a steering knuckle through a third rotating hinge; the lower swing arm connecting rod is connected with the steering knuckle connecting rod through a second rotating hinge; a damper piston rod slides along a central axis of a damper work cylinder barrel; the upper end of the damper piston rod is connected with a frame through a vibration isolating block assembly with a bearing; the damper work cylinder barrel is fixedly connected with the steering knuckle; an axle shaft sleeve is formed in the steering knuckle; a hub is supported on the axle shaft sleeve through a hub bearing; a steering knuckle arm on the steering knuckle is connected with a steering pull rod through a spherical hinge; one end of a universal joint is fixedly connected with a gearbox output shaft; the other end of the universal joint is fixedly connected with an axle shaft; the axle shaft is fixedly connected with the hub; and the hub is fixedly connected with a brake rotating piece and a rim. The Macpherson suspension wheel rim electric driving system disclosed by the invention has the advantages that a motor casing, the gearbox casing and a lower swing arm of a Macpherson suspension are integrated, the vibration of a motor relative to the frame is reduced and the equivalent unsprung weight is light.

Description

technical field [0001] The invention belongs to the field of electric vehicle chassis and transmission, and in particular relates to a McPherson suspension wheel side electric drive system for steering wheels. Background technique [0002] At present, the main structural feature of the wheel-side electric drive system represented by electric wheels is that the drive motor is installed in or near the drive wheel, which has the advantages of short drive transmission chain, efficient transmission, and compact structure. At the same time, the torque of each driving wheel in the wheel drive system can be independently controlled. The wheel motor is not only the information unit of the car, but also the fast-response control execution unit, which is conducive to the realization of high-performance control functions that are difficult to achieve on traditional cars, thereby improving harsh conditions. Driving performance under road conditions. [0003] However, in the general whee...
