Problems solved by technology

The modular structure can automatically realize many functions such as supporting the vehicle body load, driving and braking, steering and shock absorption, and the whole system has a compact structure; The space in the wheel is tight, so the connection point between the suspension and the steering knuckle is arranged outside the wheel, resulting in an excessively large kingpin offset, which is not conducive to steering portability and handling stability

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0022] An electric wheel independent suspension structure with four control arms, such as figure 1 , figure 2 and image 3 , including wheels 25, hub motors, steering knuckles 4, vehicle frame 26, steering tie rods 15 and independent suspension.

[0023] The in-wheel motor includes a rotor 1, a stator 2, a stator bracket 3, a brake caliper 27 and a brake disc 28. The stator bracket 3 is arranged on the wheel 25 and is fixedly connected to the steering knuckle 4 by bolts. The rotor 1 is coaxially arranged on the stator bracket 3. Above, the stator 2 is sleeved on the stator bracket...

Abstract

The invention relates to an electric wheel independent suspension structure with four control arms. The independent suspension structure comprises a wheel (25), a hub motor, a steering knuckle (4), aframe (26) and an independent suspension. The steering knuckle (4) is fixedly connected with the hub motor. The independent suspension comprises a vibration reduction assembly and a control arm assembly. The control arm assembly comprises a first upper control arm (9), a second upper control arm (13), a first lower control arm (18) and a second lower control arm (20) of which the two ends are connected with the steering knuckle (4) and the frame (26) through spherical hinges respectively, wherein the extension lines of the connecting lines of the centers of spherical hinges at the two ends ofthe first upper control arm (9) and the second upper control arm (13) intersect at an upper virtual spherical hinge point (6), and the extension lines of the connecting lines of the centers of spherical hinges at the two ends of the first lower control arm (18) and the second lower control arm (20) intersect at a lower virtual spherical hinge point (24). Compared with the prior art, the structurehas the advantages of space saving, strong flexibility and the like.

Description

technical field [0001] The invention relates to the field of electric vehicle chassis and transmission, in particular to an electric wheel independent suspension structure with four control arms. Background technique [0002] In recent years, the investment of the country and enterprises in the field of electric vehicles has been continuously increasing, and there are many driving forms of electric vehicles on the market, mainly including centralized motor drive and distributed motor drive, and distributed drive can be divided into two types: For wheel drive and hub drive. The hub electric wheel assembly is the core power component of the hub-driven electric vehicle. Due to its 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 the performance of the vehicle under severe road conditions. The driving performance has become a researc...
