Electronic power-assisted steering system

Abstract

The invention discloses an electronic power-assisted steering system. The system comprises a frame, a handle, a handle shaft, a rotating shaft lock plate, an angle sensor, a control module, a shock absorbing support, a travel driving motor, a steering driving motor, a speed reduction box and a driving wheel, wherein the lower end of the handle shaft drives a movable part on the angle sensor to rotate through a gear so that the rotating angle of the handle shaft can be recognized, the control module is connected with the angle sensor, the steering driving motor and the travel driving motor so that signals collected by the sensor can be fed back to the control module, and the control module is used for controlling the steering driving motor to rotate. The shock absorbing support is reasonable and firm in structure, the driving wheel and a driving system are effectively arranged so that the driving wheel, the driving system and the frame can be elastically connected, and an electrical carrying vehicle can bear large impact caused by a hollow ground so that the driving system can work more stably; the vertical alternating-current driving motor is used for driving, the transverse size of the independent driving system is effectively reduced, the structure is simplified, and the layout is more reasonable.

Description

technical field [0001] The invention relates to an electronic power steering system. Background technique [0002] In the prior art, in order to facilitate the steering of large-tonnage electric pallet trucks, an electronic power steering system will be installed. The signal is fed back to the motor used to control the rotation of the steering wheel. The electronic power steering system needs to integrate the steering structure and the driving drive structure, so the structure is relatively complicated. How to ensure the reliable and stable operation of the system is a problem that must be considered during design. The shock-absorbing structure design of the existing electronic power steering system is unreasonable, so that when the electric pallet truck is subjected to the impact caused by large potholes, it is easy to cause structural damage to the system and affect normal use. Contents of the invention [0003] The object of the present invention is to overcome the abo...
