Abstract

The invention discloses a performance test platform for an electric power steering system of an industrial transport vehicle, which comprises a test bed support, an EPS system assembly and a detectionsystem, wherein the EPS system assembly and the detection system are both installed on the test bed support; the test bed support comprises a test bed bottom plate, an inclined support adjusting plate and an inclined support; the detection system comprises a torque sensor I, a torque acquisition device, a torque sensor II, an electronic control unit ECU and an input motor control unit; the EPS system assembly comprises a steering wheel, an input shaft, a torque input large gear, a coupler I, a coupler II, a bevel gear shaft I, a bevel gear I, a bevel gear II, a bevel gear shaft II, an assisting large gear, a large gear shaft, a coupler III, a coupler IV and a magnetic powder brake which are connected in sequence. The platform can be suitable for performance test of the electric power steering system of various industrial transport vehicles.

Description

technical field [0001] The invention relates to the field of performance testing of vehicle electric power steering systems, in particular to a performance testing platform for electric power steering systems of industrial transport vehicles. 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. at a relatively basic stage. The performance of EPS is directly related to the safety and reliability of the vehicle, driving comfort, sensitivity and lightness of operation. [0003] The electric power steering system can be mechanically divided into mechanical steering system and power steering system. The main component of the mechanical steering system in most electric power steering systems is the torque signal acquisition structure, which cannot complete the power steering of different styles ...
