Shockproof support for electronic power-assisted steering system

Abstract

The invention discloses a shockproof support for an electronic power-assisted steering system. The shockproof support for the electronic power-assisted steering system comprises a fixed frame vertical plate, a guide column fixing pressing plate, a floating frame base plate, guide columns, a guide ring, guide cylinders, supercharging springs, spring seats, a limiting bolt, an upper left fixing base, an upper right fixing base, a lower left fixing base and a lower right fixing base, wherein the two guide columns are symmetrically arranged on a fixed frame, the two guide cylinders are symmetrically fixed to the floating frame base plate, the floating frame base plate is connected with the fixed frame in a sliding mode, the two spring seats are symmetrically arranged on the floating frame base plate, the lower end of each spring seat is fixed to the floating frame base plate, the supercharging springs are arranged on the spring seats in a sleeving mode, and the upper end and the lower end of each supercharging spring abut against the guide column fixing pressing plate and the floating frame base plate respectively. The shockproof support for the electronic power-assisted steering system is reasonable in structure and firm, a driving wheel and a driving system are effectively arranged, elastic connection of the driving wheel, the driving system and a vehicle frame is achieved, an electric van can bear impact generated when the electric van travels on the ground with big pits, and thus the driving system can operate more stably.

Description

technical field [0001] The invention relates to a shock absorber bracket for 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 purpose of the present in...
