Problems solved by technology

At present, there is no special test device for the performance test of the automotive continuously variable transmission valve body in China. It is necessary to import such a test device or send the valve body to foreign countries for performance testing. The test cost is high and the test period is long, which is not conducive to product development.

Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the present invention is composed of a control machine 1 and a testing machine 2 connected. The control machine 1 includes an operation console and its internal control circuit. The testing machine 2 includes a frame assembly 3, a hydraulic system 4, a hydraulic oil tank 5, and a test chamber 6. The hydraulic system 4 is connected to the hydraulic oil tank 5 and is located at the bottom of the frame assembly 3. The test chamber 6 is located at the top of the frame assembly 3. The frame An oil mist collector 7 is installed on the top of the assembly 1. This is because during the high-temperature test, high-temperature oil will be generated in the experimental cabin, which is unfavorable to the observation of the test conditions in the experimental cabin, and the oil will condense in the...

Abstract

The invention relates to a testing device for CVT valve body performance testing, which is formed by connecting a controlling machine and a testing machine; the controlling machine comprises an operation table and a control circuit inside the operation table; and the testing machine comprises a framework assembly, a hydraulic system, a hydraulic oil box and a testing cabin, wherein the hydraulic system is connected with the hydraulic oil box and positioned at the bottom of the framework assembly, the testing cabin is positioned at the upper part of the framework assembly, and an oil mist collector is installed at the top of the framework assembly. The invention realizes the performance testing for the pressure, the temperature and the like of an automobile stepless speed-changer valve body by adopting a mechanical-electrical-hydraulic combined mode, has the advantages of simple structure, convenient use and high testing precision, can be used for carrying out automated performance testing on the automobile stepless speed-changer valve body according to testing requirements, reduces the testing expenses and shortens the testing period.

Description

technical field [0001] The invention relates to a test device for an automobile transmission (CVT), in particular to a test device for testing the performance of a CVT valve body. Background technique [0002] With the rapid development of China's automobile industry and the rapid and large number of automobiles entering Chinese families, domestic automobile manufacturers are vigorously developing automobile products with independent intellectual property rights. Key components of the transmission. At present, there is no special test device for the performance test of the CVT valve body in China. It is necessary to import such a test device or send the valve body abroad for performance testing. The test cost is high and the test period is long, which is not conducive to product development. Contents of the invention [0003] The applicant has carried out research and improvement for the above-mentioned problems, and provides a CVT valve body performance test test device,...
