Abstract

The invention discloses a comprehensive testing system for high-temperature pulse of a steering power hose of a motor vehicle, which is high in integration level, adjustable in pressure pulse curve and extremely low in energy consumption. The comprehensive testing system comprises an oil tank and a bracket device arranged at one side of the oil tank, wherein the measured hose is fixed on the bracket device. The comprehensive testing system is characterized by comprising a hydraulic power loop, a control loop and a high-temperature pulse loop. The comprehensive testing system disclosed by the invention has the advantages that on principle selection of the hydraulic control system, an accumulator-pressurizing mode is adopted for pressurizing the measured hose; and compared with the general principle that a motor pump set is directly adopted for pressurizing the measured hose, the energy is greatly saved and the testing cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of fluid transmission and control, in particular to a high-temperature pulse comprehensive test system for steering power hoses of motor vehicles. Background technique [0002] Motor vehicle steering power hose high temperature pulse comprehensive test system is a set of electromechanical integration device for testing the high temperature pulse resistance of motor vehicle steering power hose. Steering power hose is an important product of the current national motor vehicle products, and its high temperature pulse resistance test is an important performance testing link. [0003] At present, the existing power steering hose test benches on the market have the following structural features: [0004] 1. Heat dissipation method: The hydraulic oil needs to be heated to 135°C, and then the hydraulic oil is cooled back to the hydraulic station. A heat dissipation device is required. Generally, air-conditioning re...
