Pressure detection device of power steering system

Abstract

The invention discloses a pressure detection device of a power steering system. The power steering system includes a steering wheel assembly and a steering engine, and the pressure detection device includes an electric motor, an oil pump, an oil pot, a tee device, pressure gauges and oil pipes, wherein the electric motor is connected with the oil pump to provide motive power for the oil pump; the oil inlet of the oil pump is connected with the oil outlet of the oil pot through the oil pipe; the oil outlet of the oil pump is connected with a first oil port of the tee device through the oil pipe; a second oil port of the tee device is connected with the oil inlet of the steering engine; the pressure gauge is installed at a third oil port of the tee device and used for detecting the inlet pressure value of the steering engine; the oil outlet of the steering engine is connected with the oil return opening of the oil pot through the oil pipe; and the pressure gauge is arranged at the oil return opening of the oil pot and used for detecting the oil return pressure valve. The device has a simple structure, is convenient to operate, performs the multi-point detection on the oil pipe pressure of a power steering system, and simulates the pressure detection on the power steering system.

Description

technical field [0001] The invention relates to the technical field of automobile test and detection, in particular to a pressure detection device for a power steering system. Background technique [0002] In order to verify the value of the power steering system during the loading process and the working status of the steering power oil pipe, the pressure of the oil pipe in the power steering system is generally tested according to the parameters during the loading process, so as to realize the performance parameters of the power steering system and the whole vehicle. match. At present, the oil pipe pressure in the power steering system is generally detected through the simulated vehicle detection system provided by the main engine factory. The structure of the simulated vehicle detection system is complex, expensive, inconvenient to install and operate, and it is impossible to achieve multiple oil pipe pressures in the power steering system. point detection function.
