Abstract

The invention discloses a continuously variable transmission oil pump performance detection test apparatus used for detecting the performance parameters of an automobile continuously variable transmission oil pump at different working conditions. The performance detection test apparatus comprises a test work bench, a hydraulic part and a control part; the hydraulic part is connected with a tube of the test work bench, the control part is connected with the test work bench and a hydraulic part line, the test work bench is provided with a machine frame which is provided with a drive motor, a transmission shaft and a detected oil pump, a torsionmeter is arranged between the transmission shaft and the detected oil pump, and the drive motor drives the transmission shaft for rotation to realize the rotation of the detected oil pump. In the performance detection test apparatus, an electromechanical and hydraulic combination mode is adopted to be capable of detecting main performance parameters, such as load flow, leakage flow, volumetric efficiency and the like of the continuously variable transmission oil pump at different temperatures, rotating speeds, torque moments and load pressures. The performance detection test apparatus has high test precision, and can help realize the full automation of the test process according to the proposed scheme.

Description

technical field [0001] The invention relates to an oil pump performance detection test device, in particular to a test device for detecting performance parameters of an automobile continuously variable transmission oil pump under different working conditions. Background technique [0002] The domestic automobile industry has not made great progress in the research of continuously variable transmission, mainly because of the performance requirements of key components and testing theories and methods, especially in the performance near the limit conditions and the simulation of the limit working environment. There has been a big breakthrough. The performance test of the oil pump, which is the key component of continuously variable transmission, is mainly based on the generality. However, it is more difficult to test the performance parameters of the oil pump under the conditions of high speed, high temperature and strong torque, especially the test control accuracy and test acc...
