Abstract

The invention discloses a testing device of an electric power steering system, in order to overcome the problems of low control accuracy of a resistance device, complicated drive system, simple vehicle model, and oil leakage of a hydraulic system. The testing device of the electric power steering system comprises a T-shaped groove platform, two linear motor assembly mechanisms, two steering gear stationary fixture assemblies, a steering pipe column stationary fixture assembly, a steering wheel simulation driving mechanism and a driving simulator assembly; a voltage stabilizing power supply, a power supply cabinet and a measurement and control cabinet are fixed on the foundation around the T-shaped groove platform; the steering gear stationary fixture assemblies are fixed on the left side of the T-shaped groove platform; linear motors are installed on the T-shaped groove platform at the outer side of the stationary steering gear stationary fixture assemblies; output ends of the linear motors are connected with two ends of steering gears fixed on the steering gear stationary fixture assemblies; the driving simulator assembly is fixed on the right side of the T-shaped groove platform; the steering pipe column stationary fixture assembly is fixed on the T-shaped groove platform between the steering gears and the driving simulator assembly; the steering wheel simulation driving mechanism is inserted on a steering pipe column.

Description

technical field [0001] The present invention relates to a test device for testing the performance of auto parts. More specifically, the present invention relates to a test device capable of performing resistance simulation of automobile electric power steering, real-time vehicle dynamics simulation and sampling control, and at the same time conducting electric power steering system assembly. Automotive electric power steering system test device for component and sub-assembly performance tests. Background technique [0002] Electric Power Steering (EPS for short) technology has been greatly developed in China, and it is currently a research hotspot in domestic steering technology. How to test the performance of the electric power steering system and evaluate the electric power steering control strategy in the laboratory environment is a problem that researchers need to consider. Reasonable loading method, realistic simulation environment and real-time sampling control are th...
