System for loading tested vehicle using fixed loading device and traction power test method

Abstract

The invention provides a system for loading a tested vehicle using a fixed loading device, which can effectively improve the accuracy, stability and safety of traction test on a tested vehicle, reducethe labor intensity of test personnel, expand the range of applications of new technologies, and enrich test means in the industry. The system for loading a tested vehicle using a fixed loading device includes a driving device and a vehicle state parameter measuring device. The driving device includes a frame, a plunger pump, a hydraulic station, a transmission mechanism, a winch, a steel wire rope and a reversing motor. The plunger pump, the transmission mechanism, the winch and the reversing motor are arranged on the frame. The hydraulic station is connected with the plunger pump. The output end of the plunger pump is connected with the transmission mechanism. The transmission mechanism and the reversing motor are connected with the winch. The winch is connected with a tested vehicle via the steel wire rope. The vehicle state parameter measuring device is arranged on the tested vehicle and is used for collecting the state parameters of the tested vehicle.

Description

technical field [0001] The invention relates to a test device, in particular to a system for loading a vehicle under test by using a fixed loading device and a test method for traction power. Background technique [0002] In recent years, my country's agricultural mechanization has made great achievements, and the agricultural machinery industry has made great progress. The traction power test is one of the important test items in the process of vehicle identification and quality inspection. Through this test, important performance indicators such as the maximum traction force and maximum traction power of the tested vehicle can be obtained. These indicators are crucial to determine whether the quality of the tested vehicle is qualified or whether it meets the design requirements. [0003] The application of traction load loading system began in the late 1920s, but so far, only a few research institutes and production departments in the world have developed various types o...

Problems solved by technology

[0006] 2) The chassis vehicles are all refitted with all-wheel drive vehicles or the vehicles under test, and have self-propelled capabilities, but the refitting methods and structures are different;

[0007] 3) The test parameters of the dynamometer are complete, but most of them cannot achieve continuous real-time measurement of the test process, and some load vehicles have self-control functions; the test process is labor-intensive, the test cycle is long, and the accuracy of the test results is low

Most of the substitute equipment has been used in China for a long time, and its disadvantages are: high test cost, low efficiency, unstable loading control, and low reliability of results
