Electrical power steering drive assembly

Abstract

The invention discloses an electrical power steering drive assembly. The electrical power steering drive assembly is characterized by comprises a frame, a handle, a handle shaft, a rotating shaft lock plate, an angle sensor, a control module, a vibration avoidance support, a running drive motor, a steering drive motor, a reduction gearbox and a drive wheel. The vibration avoidance support comprises an upper support, a lower support, a drive base, slide rods, damping springs, an adjustment drive cylinder, an upper spring seat, an adjustment spring and a lower spring seat. An elastic adjustment structure formed by the adjustment drive cylinder, the upper spring seat, the adjustment spring and the lower spring seat on the vibration avoidance support can provide auxiliary elastic support for the damping spring, the distance between the adjustment spring and the drive base can be adjusted by driving the adjustment drive cylinder to operate, and accordingly adjustment of damping intensity can be realized, different damping requirements can be met while damping effects are guaranteed, and a driving system can operate more stably.

Description

technical field [0001] The invention relates to an electronic power steering drive assembly. 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...
