AI Technical Summary

Problems solved by technology

The crawler tension simulation device in the form of hydraulic transmission has more hydraulic components and pipelines, the system is more complicated, and the cost of implementation is relatively high
In addition, due to the unavoidable oil leakage, it is easy to system failure, which increases the maintenance cost of the test bench
Oil leakage can also cause changes in track tension, making the test results unsatisfactory

Abstract

The invention relates to a track tensioning force simulation device and method for a track test stand, and belongs to the technical field of testing equipment of a track propelling system. The structure and method for simulating the size of track tensioning force through a loading lever and a weight are used, the size of the tensioning force can be accurately controlled easily, the structure is simple and reliable, using and maintaining cost is low, operating is simple and convenient, and the working efficiency of the testing equipment is high. Furthermore, the tensioning requirement of tested tracks with different lengths can be achieved by adjusting the length of adjusting screw rods, vibration shock and noise generated in the track testing process can be reduced through a shock absorber, the testing environment is improved, and the failure rate of the system is lowered.

Description

technical field [0001] The invention relates to the technical field of crawler track propulsion system testing equipment, in particular to a track tension force simulation device and method for a track track test bench. Background technique [0002] The crawler test bench is mainly used for the performance and matching test of the crawler and the crawler propulsion device. The track tension simulation device of the track test bench needs to be able to accurately simulate the track tension, and can be easily adjusted according to different test needs. [0003] Most of the previous tensioning force simulation devices used worm gear type and hydraulic transmission form. Force simulation device. This kind of tension simulation device relies on the worm gear and worm to drive the inducer to realize the tension of the track, and the magnitude of the tension force is difficult to control accurately. [0004] Another type of crawler tensioning device is a hydraulic transmission t...
