Abstract

The invention discloses a testing device and provides a testing device for a steering oil pump assembly, which has a simple structure, is convenient to use and can rapidly and accurately detect the steering oil pump assembly, and a testing method for the steering oil pump assembly. The invention solves the technical problems of high intensity, long detection period, high cost, incapability of carrying out durability test on each batch of new steering oil pump assembly and the like which are caused by the case that in the prior art, a steering oil pump can be detected only after being loaded. The testing device comprises a testing platform; the testing platform is provided with an oil pump fixing seat for fixing the steering oil pump assembly and a driving motor capable of driving the steering oil pump assembly to operate; an oil pipe is communicated between a high pressure oil outlet and a low pressure oil return port of the steering oil pump assembly; the oil pipe is provided with a pipeline control valve, a pressure valve and a flow valve.

Description

technical field [0001] The invention relates to a test device, in particular to a test device and a test method for a steering oil pump assembly which can quickly and accurately detect the steering oil pump assembly. Background technique [0002] With the development of social economy and the continuous improvement of living standards, people's requirements for the quality of cars are getting higher and higher. Analyze and improve to meet customer requirements. Among them, the steering oil pump assembly is the core of the automobile steering system. It is very necessary to analyze and improve its faulty parts. Long and expensive, it is impossible to carry out durability test for each batch of new steering oil pump assembly. [0003] A Chinese patent discloses a method for detecting the reliability of an automobile power steering oil pump (CN102052294B), which calculates Q1 by separately measuring the output flow Q1 of the steering oil pump under no-load operation and the o...
