EPS (Electric Power Steering) detection device

Abstract

The invention discloses an EPS (Electric Power Steering) detection device. The EPS detection device comprises a locking unit, an input transmission unit, an output end simulation resistance unit and adetection unit; the locking unit is used for supporting and clamping an EPS body; the input transmission unit is used for rotating a driving source and linked with the input end of the EPS body; theoutput end simulation resistance unit is used for applying rotation load onto the output end of the EPS body; the detection unit is used for performing detection driving and EPS detection data acquisition; and the detection unit is respectively in communication connection with the input transmission unit, the output end simulation resistance unit and the EPS. The EPS detection device disclosed bythe invention is suitable for carrying and detecting an EPS system; detection items are relatively comprehensive; automatic locking of the carried EPS system can be realized through the locking unit;the input end and the output end of the EPS system can be automatically and fixedly connected through a linkage mechanism and an interference mechanism; the whole adaptive-connection automation degreeis high; the efficiency of the flow detection operation is increased; simultaneously, the assembly adaptive-connection reliability of the EPS system is ensured; each unit has the free regulation degree; and thus, carrying and detection of different EPS systems are satisfied.

Description

technical field [0001] The invention relates to an EPS detection device and belongs to the technical field of EPS detection equipment. Background technique [0002] Electric Power Steering (EPS) is a power steering system that directly relies on the motor to provide auxiliary torque. Compared with the traditional hydraulic power steering system HPS (Hydraulic PowerSteering), the EPS system has many advantages. EPS is mainly composed of torque sensor, vehicle speed sensor, electric motor, deceleration mechanism and electronic control unit (ECU). [0003] The working stability and handling characteristics of the electric power steering system are related to the safety of driving and the performance of the whole vehicle. Therefore, it is necessary to effectively detect various performances of the steering gear and calibrate the torque sensor. [0004] The Chinese utility model patent with the authorized notification number CN206945306U discloses a test bench suitable for autom...
