Embodiment Construction

[0009] The present invention is described in detail as follows in conjunction with accompanying drawing and embodiment:

[0010] The structure of the active steering system based on electric wheel assist in the present invention, such as figure 1 As shown, including axle 1, steering straight rod 2, steering knuckle arm 3, left king pin 4, left electric wheel 5, left steering knuckle 6, left steering trapezoid 7, steering rocker arm 8, steering wheel 9, steering wheel sensor 10. Steering gear 11, steering tie rod 12, right steering trapezoid 13, right electric wheel 14, right steering knuckle 15, right kingpin 16,

[0011] Described electric wheel 5,14 is fixed on the automobile body by the suspension system of automobile. The electric energy of the car battery is transmitted to the electric wheels 5 and 14 through wires to realize the rotation drive of the electric wheels 5 and 14. The rotation signal of the steering wheel 9 is transmitted to the steering electronic control u...

Abstract

The invention belongs to the field of automobiles, and in particular relates to an electric wheel driven multiaxial automobile. The electric wheel driven multiaxial automobile is characterized by an electric wheel driven steering boost system. In the steering boost system, turning wheels of the automobile are changed into independently driving electric wheels, left and right wheels are separately controlled to rotate around a main pin actively according to signals of a steering wheel, and an additional steering boost system is not required to drive the wheels to rotate around the main pin, so that a steering system is simplified. According to the requirement of fuel economy of the automobile, steering boost can be generated only when the steering is required, so that additional energy consumption of the automobile can be reduced, and the fuel economy of the automobile is improved; meanwhile, the driving torque of each electric wheel is separately controlled, and the running stability of the automobile is improved.

Description

technical field [0001] The invention belongs to the field of automobiles, and is applicable to automobiles whose steering wheels are driven by electric wheels, in particular to a technology for realizing wheel steering by using electric wheels to actively drive the wheels to generate steering torque around the kingpin, thereby simplifying the current steering system of automobiles , to achieve electric wheel steering power assist. Background technique [0002] The electric wheel refers to the system that puts the motor together with the reduction system inside the wheel of the car to simplify the power transmission of the electric vehicle or hybrid vehicle, sometimes called the hub motor. For automobiles, especially heavy-duty trucks, due to the large load on the steering wheels, the resistance during steering is relatively large. In order to achieve greater steering assistance, only hydraulic power steering can be used. Regardless of whether the steering is turned or not, ...
