Abstract

The invention discloses an all-hydraulic steering gear test system, which comprises an oil tank, a motor pump system, a pressure and flow control valve system, a temperature control heating system, a filtering system, a circulation cooling system, an oil circuit switching control system, a steering power loading module, a bridge-type analog loading module, an oil cylinder working condition loading module, a sensor data acquisition module, an electronic control system and a computer data processing center. According to the all-hydraulic steering gear test system, the switching control of various oil circuits can be carried out by the oil circuit switching control module, the test of a load sensing type steering gear and other steering gears of the same type can be realized, the types of test items are more complete and comprise a power steering performance test, an end point sensing end point slippage test, a neutral position replaying test, a pressure loss test, an internal leakage test, a flow change rate test, a manual steering voltage efficiency test, a road sense test and the like, and the test requirements on the all-hydraulic steering gear in China and abroad can be met.

Description

technical field [0001] The invention relates to the technical field of steering gear testing systems, in particular to a full hydraulic steering gear testing system. Background technique [0002] The full hydraulic steering gear is widely used in construction machinery, vehicle steering and ship hydraulic rudders. Drivers can use it to achieve greater steering force control with a smaller operating force, and it is safe, reliable, flexible and light in performance. The full hydraulic steering gear needs to pass a number of tests before leaving the factory, and with the continuous innovation and development of the full hydraulic steering gear, there are more and more types, so the test items and requirements for different types of full hydraulic steering gears are also different. not exactly. At present, the test of the full hydraulic steering gear usually adopts a hydraulic steering gear test platform or system, such as the "steering gear test platform" disclosed in the pat...
