Problems solved by technology
[0003] The two-wheel steering is easy to control, but the turning radius of the vehicle is large, the stability is poor when turning at high speed, the space required for parking is large, and it is inconvenient to enter and exit
Four-wheel steering can overcome the above defects of two-wheel steering, but the structure of the control system is complicated and the cost is high, so it is mainly used in high-end cars
Therefore, the steering device disclosed in patent 200710017644.1 limits the flexibility and complex functions of the vehicle, and can only be used for position changes when the vehicle is close to a stop state, and cannot be applied to the motion control of the vehicle in the normal driving state

Embodiment Construction
[0016] The structural principle and working principle of the vehicle auxiliary steering device of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] figure 1 It is a structural schematic diagram of one of the wheels of the vehicle auxiliary steering device of the present invention, including the hub motor [1], the brake [2], the controller [6], the battery [7], the wheel turning surface [j], and the centerline of the wheel turning axis The wheel of [k] is constituted by the steering axis of the center line [h] of the steering axis which is not in the same plane as the wheel turning surface [j].
[0018] The drive signal inlet [8] of the wheel hub motor [1] is connected to the battery [7] by driving the steering friction lock drive winding [4] and the controller [6] through the steering shaft; the steering signal inlet [9] of the wheel hub motor [1] ] through the steering shaft to drive the steering friction lock steer...

The invention relates to an electric motor car driving chassis, which comprises a hub motor, a brake, a controller, a storage battery, a steering shaft, a steering shaft braking electromagnetic friction lock and a steering shaft braking steering friction lock. Through arrangement of the electromagnetic friction lock on the steering shaft, when the vehicle is accelerated, decelerated, steered and braked, the vehicle motion is controlled by changing the lock force of the electromagnetic friction lock and balancing the steering moment from the wheel drive force to the steering shaft. The electric motor car driving chassis can conveniently realize the four-wheel steering function.
Description
technical field [0001] The invention relates to the field of electrically driven vehicles, in particular to a driving chassis of an electric vehicle. Background technique [0002] With the continuous development of society, the number of vehicles is increasing, and the roads are somewhat narrow, and the space required for parking vehicles is becoming more and more tense. So in the process of parking or U-turn will cause vehicle jam phenomenon, its main cause is due to the incomplete function of existing vehicle steering gear. The steering mechanism of existing vehicles mostly adopts two-wheel steering under the control of steering wheel and steering gear, and a few high-grade cars adopt four-wheel steering. [0003] Two-wheel steering is easy to control, but the turning radius of the vehicle is large, the stability is poor when turning at high speed, the parking space required for parking is large, and it is inconvenient to enter and exit. Four-wheel steering can overcome ...
