Simulation test device for automobile electric power steering system

Abstract

The invention provides a simulation testing device for an automobile electric power steering system, and relates to the technical field of automobile electric power steering testing. A driving device is mounted in the fixing assembly, a height adjusting device is mounted at the top of the driving device, and a control assembly is mounted at the top of the height adjusting device; the recording device is installed in the control assembly, a rotating assembly and a switching assembly are installed at the bottom of the recording device, and a limiting device is installed at the bottom of the switching assembly; according to the invention, it is convenient for testers to properly adjust according to their heights, the simulation effect during testing is improved, it is convenient for the testers to know the rotation angle of the torque input rod after testing is completed, and the testing precision of the automobile electric power steering system is improved; the problems that a tester cannot properly adjust the height of the device according to the height of the tester and cannot accurately know the rotation angle of the steering wheel are solved.

Description

technical field [0001] The invention relates to the technical field of automobile electric power steering testing, in particular to a simulation test device for an automobile electric power steering system. Background technique [0002] In the performance test of the automobile electric power steering system (EPS), it is necessary to simulate the scene of the driver turning the steering wheel, that is, to apply a certain direction of torque to the EPS by turning the steering wheel, and the EPS makes various calculations and judgments according to the applied torque, and then drives the motor And other accessories drive the load to run; judge whether the performance of the EPS is good by monitoring the working conditions of the internal electrical signals of the EPS. [0003] However, in the current test of the electric power steering system of automobiles, some use real steering wheels and some use simulated steering wheel devices; due to the differences in the heights of th...
