AI Technical Summary

Technical Problem

Existing hydraulic power steering vane pump performance test benches cannot simulate extreme conditions such as temperature rise and ultra-high temperature under extreme operating conditions of real vehicles.

Method used

A special working condition simulation test platform for a vehicle was designed, including a hydraulic circuit system comprising an oil tank, manual valves, a pump and drive unit, a pressure sensor, a flow meter, a manual pressure regulating valve, a solenoid valve, and a filter element, forming a closed loop. The oil circuit is controlled by the manual valves and solenoid valves, the pump and drive unit provides high-pressure oil flow, the pressure sensor and flow meter monitor the status, and the filter element filters impurities.

Benefits of technology

It enables accurate simulation testing of vehicles under extreme working conditions, and can simulate extreme conditions such as temperature rise and ultra-high temperature under short-term high pressure and high speed, meeting the performance testing needs of engineering vehicles under harsh conditions.

Abstract

The utility model discloses a carrier special working condition simulation test platform, its structure includes hydraulic circuit system. Hydraulic circuit system includes oil tank, manual valve, pump and drive unit, pressure sensor, flowmeter, manual pressure regulating valve, solenoid valve and filter core, forms closed loop. The oil tank stores lubricating oil, and manual valve adjusts lubricating oil flow, and controls the on-off of circuit. Pump and drive unit include hydraulic pump and drive motor, and pressure sensor measures system pressure, and flowmeter measures the output flow of pump, and solenoid valve controls the on-off and switching of oil circuit according to test demand, when testing, first opens manual valve, starts pump and drive unit, and lubricating oil is output after pressurization. Pressure gauge shows pressure value in real time, and flowmeter measures flow. Adjust pressure through manual pressure regulating valve, and solenoid valve controls oil circuit switching. Filter core filters impurities and pollutants in hydraulic oil. After testing, closes manual valve, and stops pump and drive unit work.
