Abstract

The invention relates to a test system of a hydraulic control device of a gearbox. The test system comprises a main oil tank, an oil supply oil way structure, a flow test loop structure and a pressuretest loop structure, wherein the oil supply oil way structure is in circular communication with the main oil tank and the hydraulic control device; the flow test loop structure is in communication with the main oil tank and the hydraulic control device; the pressure test loop structure is in communication with the main oil tank and the hydraulic control device; the flow test loop structure comprises a flow test oil tank, a flow test oil way and a flow test oil return oil way; the flow test oil way is in communication between the hydraulic control device and the flow test oil tank; the flow test oil return oil way is in communication between the flow test oil tank and the main oil tank; the pressure test loop structure comprises a pressure test oil tank, a pressure test oil way and a pressure test oil return oil way; the pressure test oil way is in communication between the hydraulic control device and the pressure test oil tank; and the pressure test oil return oil way is in communication between the pressure test oil tank and the main oil tank. The test system aims to solve the problems that an effective and reliable test system is lacked in the prior art, and the successful development efficiency of the hydraulic control device is influenced.

Description

technical field [0001] The invention relates to the technical field of gearbox testing, in particular to a testing system for a gearbox hydraulic control device. Background technique [0002] With the vigorous development of China's domestic automobile industry, the domestic automatic transmission industry is also developing continuously. The hydraulic control device is the most important core component of the automatic transmission. The test verification of the hydraulic control device is the most important part in the development process of the hydraulic control device. An important link, an effective and reliable test system is the guarantee for the successful development of hydraulic control devices. However, such an efficient and reliable testing system is still lacking, affecting the efficiency of successful development of hydraulic control devices. Contents of the invention [0003] Based on this, the present invention provides a testing system for a transmission h...
