Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0023] Such as figure 1 As shown, a pure electric power steering device includes a steering control system 1 and a steering assist system 2 . The steering assist system 2 includes a booster motor controller 3 , a booster motor 4 , a multi-stage planetary reduction mechanism 8 and a steering gear output shaft 21 .

[0024] In the present invention, the power steering system 2 and the steering control system 1 adopt two different types of speed reduction mechanisms, and the output torques act on the output shaft 21 of the steering gear together with two independent transmission lines. Specifically, the output torque of the booster motor 4 is decelerated and increased by the shaft extension end of the booster motor 4 through the multi-stage planetary reduction mechanism 8, and ...

Abstract

The invention relates to a pure-electric-power-assisted steering gear. The pure-electric-power-assisted steering gear comprises a steering control system (1) and a steering assistance system (2). The steering assistance system (2) comprises an assistance motor controller (3), an assistance motor (4), a multi-stage planet speed reduction mechanism (8) and a steering gear output shaft (21). The two ends of the assistance motor controller (3) are connected with the steering control system (1) and the assistance motor (4) respectively. The output end of the assistance motor (4) is connected with the input end of the multi-stage planet speed reduction mechanism (8). The output end of the multi-stage planet speed reduction mechanism (8) is connected with a steering gear output shaft (21). The steering gear output shaft (21) is connected with the steering control system (1). The electric-power-assisted steering gear can output large torque, solves limitation, on the aspect of application, of a current electric-power-assisted steering gear, and fills in the blank that pure-electric-power-assisted steering gears can be used for medium and heavy vans.

Description

technical field [0001] The invention relates to the technical field of automobile steering gears, in particular to a pure electric power steering gear. Background technique [0002] Today, electric vehicles are the development direction of the times, and electric power steering has also become the development direction of the steering gear industry. At present, the electric power steering gear on the market is mainly used for the rack and pinion shaft power steering gear of small passenger cars, commercial vehicles such as pure electric buses, new energy buses, heavy vehicles and various types of passenger vehicles. The car still has to use a hydraulic power steering gear, and the pure electric power steering gear that can provide a large output torque is still a blank at home and abroad. [0003] Compared with the hydraulic power steering system, the electric power steering system does not use hydraulic devices, and there are no oil pumps, oil pipes, pressure flow control ...
