Automobile steering non-overshoot electromagnetic power assisting device

Abstract

The invention relates to an automobile steering non-overshoot electromagnetic power assisting device, which consists of a torque sensor 3, an aspect sensor 4, an electromagnetic power assisting disk 5 and an electric control board 6, wherein a revolving shaft of the torque sensor 3, a revolving shaft of the aspect sensor 4 and a shaft of a rotor of the electromagnetic power assisting disk 5 are coaxial with a steering shaft 2 of a steering wheel; the torque sensor 3 and the aspect sensor 4 are used for transmitting a torque signal and an aspect signal of the steering wheel operated by a driver to the electric control board 6 through a single wire 9; and the electric control board is used for controlling the electromagnetic power assisting disk 5 through an electric control power supply line 7. In the automobile steering non-overshoot electromagnetic power assisting device, power-assisted steering is realized by adopting the electromagnetic power assisting disk instead of a motor, so that a steering command is not required to be transmitted to the motor, and overshoot is eliminated fully; and the steering disk and a steering wheel are connected through pure mechanical components, so that the road effect is direct, the structure is extremely simple, the reliability is improved, the manufacturing cost is lowered, the aims of convenience, energy saving and rapid response are fulfilled, and the automobile steering non-overshoot electromagnetic power assisting device has a plurality of advantages and a great market prospect.

Description

technical field [0001] The invention relates to an automobile steering non-overshooting electromagnetic booster, which belongs to the technical field of vehicle engineering. Background technique [0002] At present, the steering power of automobiles mainly adopts two types: mechanical hydraulic power steering and electric power steering. 1. Mechanical hydraulic booster system: The main components of the mechanical hydraulic booster system include hydraulic pumps, oil pipes, pressure fluid control valves, V-shaped transmission belts, oil storage tanks, etc. This power assist method is to convert part of the engine power output into hydraulic pump pressure, and apply auxiliary force to the steering system to make the tires turn. According to the different fluid flow modes in the system, it can be divided into normal pressure hydraulic power assist and constant flow hydraulic power. help. In the two kinds of hydraulic power assist, the steering oil pump is an essential part, ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the relatively high energy consumption of the existing mechanical hydraulic power assist system, the pipeline structure is very complicated, the number of various valves for controlling oil is large, and the system in the electric power steering system isolates the direct connection between people and the road surface, making the road feel Insufficient information, defects such as overshooting, in order to avoid the many shortcomings of the two types of power steering systems, the present invention provides an automobile steering without overshooting electromagnetic booster, which uses an electromagnetic main force disc to achieve steering assist
