Electric power-assisted steering device for explosion-proof rubber-tyred vehicle

Abstract

The invention discloses an electric power-assisted steering device for an explosion-proof rubber-tyred vehicle, which can realize the electric steering of an underground explosion-proof rubber-tyred vehicle and is a novel steering technology. The power-assisted steering device works in a time-sharing manner, and the motor only provides assistance during steering, so that the energy consumption can be obviously reduced. The steering assisting power can be adjusted through software, steering portability at the low speed and operation stability at the high speed can be considered, and the return performance is good. The device is compact in structure, light in weight and easy to maintain. By changing the setting of a program, the electric power-assisted steering system can be matched with different explosion-proof rubber-tyred vehicles, serialization can be formed, and the intelligent control level of the underground explosion-proof rubber-tyred vehicle is greatly improved.

Description

technical field [0001] The invention belongs to the field of underground explosion-proof rubber-tyred vehicles, in particular to an electric steering device for underground explosion-proof rubber-tyred vehicles. Background technique [0002] At present, with the extensive use of underground explosion-proof rubber-tyred vehicles, the requirements for rubber-tyred vehicles are getting higher and higher. The steering devices of explosion-proof rubber-tyred vehicles used underground are basically two types of steering devices: mechanical hydraulic power assist and electronic hydraulic power power steering. The mechanical hydraulic 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. This requires a large consumption of engine power, resulting in insufficient power for rubber-tyred vehicles. Although the electronic hydraulic power steering system is no longer direc...

AI Technical Summary

Problems solved by technology

The mechanical hydraulic 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. This requires a large consumption of engine power, resulting in insufficient power for rubber-tyred vehicles.

Although the electronic hydraulic power steering system is no longer directly driven by the engine, but by the electric motor, the structure of the power steering oil pump, hose, hydraulic oil, conveyor belt and pulley installed on the engine, etc. necessary for the hydraulic power steering system is complex. Assembly is not flexible
