Problems solved by technology

[0002] At present, there is no relevant test method for the power loss of the crawler propulsion device of domestic tracked vehicles. Most of the relevant research is based on foreign test data, and there are certain differences in the structure of the domestic and foreign crawler propulsion devices. The reliability of the data is not high, so there is an urgent need for a test method for the power loss of the crawler propulsion device, which is used to test the power loss of the crawler propulsion device, so as to improve the research level of the power loss of the crawler propulsion device

Abstract

The invention belongs to the technical field of experiment testing methods, and particularly relates to a testing method of force flow closure power loss of a track propulsion device. According to thetesting method, a variable-frequency and variable-speed motor is utilized as a power device of a testing device, and a rotation speed and torque sensor at the front end of the testing device is utilized as a measuring device of the testing device. The testing method is mainly applied in different states of track pre-tensioning force, the power loss of the track propulsion device is tested, basisis provided for research, development and improvement of design of the power loss of the track propulsion device, and the problem that the power loss of the track propulsion device is lack of testingmethods of is solved.

Description

technical field [0001] The invention belongs to the technical field of test and test devices, and in particular relates to a test method for force-flow closed-type power loss of a crawler propulsion device. Background technique [0002] At present, there is no relevant test method for the power loss of the crawler propulsion device of domestic tracked vehicles. Most of the relevant research is based on foreign test data, and there are certain differences in the structure of the domestic and foreign crawler propulsion devices. The reliability of the data is not high, so there is an urgent need for a test method for the power loss of the crawler propulsion device, which is used to test the power loss of the crawler propulsion device, so as to improve the research level of the power loss of the crawler propulsion device. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to provi...
