Abstract

An electric power steering system testing device comprises a horizontally-arranged bearing table, a load mechanism used for being connected with an output shaft of a steering column assembly is arranged below the bearing table, and an output shaft of a load motor of the load mechanism is sequentially connected with a load torque angle sensor and the output shaft of the steering column assembly. A loading mechanism used for being connected with an input shaft of the steering column assembly is arranged above the bearing table, and an output shaft of a loading motor of the loading mechanism is sequentially connected with a loading torque angle sensor and the input shaft of the steering column assembly; the lifting mechanism drives the first bracket to slide on the guide columns through a first driving motor and a vertical first lead screw nut pair which are fixedly connected to the supporting plate, and vertical position adjustment of the loading mechanism is achieved; the clamping mechanism on the bearing table is used for clamping a steering column assembly and comprises a clamping device, an up-down adjusting device and a front-back adjusting device, wherein the up-down adjusting device and the front-back adjusting device drive the clamping device to move up and down and front and back. The device is reasonable in structure, good in test universality and convenient to install and debug.

Description

technical field [0001] The application relates to the technical field of testing of automobile assembly production lines, in particular to an electric power steering system testing device. Background technique [0002] Electric Power Steering (EPS for short) is a power steering system that directly relies on the motor to provide auxiliary torque. In recent years, it has become a research hotspot in the domestic vehicle field. The performance of EPS is directly related to the safety and reliability of the vehicle. performance, driving comfort, agility and lightness of operation. [0003] It is very necessary to conduct a series of performance tests on the electric power steering system before it is put into production, and it is also a problem that researchers need to focus on. However, at present, because the various types of test benches and test methods are not the same, the test methods used are also quite different. [0004] After the electric power steering system is ...
