Test track walking mechanism for vehicle ground mechanics soil tank test bench

Abstract

The invention relates to a test track walking mechanism for a vehicle ground mechanics soil tank test bench. The test track walking mechanism comprises a vehicle frame; the front end of the middle of the vehicle frame is provided with a front bearing supporting seat; the rear end of the middle of the vehicle frame is provided with a rear bearing supporting seat; the rear bearing supporting seat is provided with a rear track driving shaft through a bearing; the front bearing supporting seat is provided with a front track driving shaft through a bearing; the outer end of the front track driving shaft is sleeved with a front connection flange; the middle of the front track driving shaft is sleeved with a track driving chain wheel; the cross section of the outer end of the rear track driving shaft is a hexagon or a square; the outer end of the rear track driving shaft is sleeved with a rear connection flange; the inner end of the rear track driving shaft and the inner end of the front track driving shaft are connected with end surfaces of a disc type torque sensor respectively; and the shell of the disc type torque sensor is connected with the frame through a torque sensor fixing plate. The test track walking mechanism for the vehicle ground mechanics soil tank test bench can measure the stressed state of the soil tank test bench, authentically simulate the actual operating states of tracks, and simulate actual height in an experiment.

Description

technical field [0001] The invention relates to a crawler belt traveling mechanism for a vehicle ground mechanics soil tank test bench for vehicle ground mechanics. Background technique [0002] Existing soil tank test rigs are usually equipped with wheels and subjected to ground mechanics tests. In the prior art, there is no track that can be installed on the soil tank test rigs for ground mechanics tests. Contents of the invention [0003] The object of the present invention is to provide a kind of test track that can be applied to the soil tank test bench to measure its stress state, can truly simulate the actual running state of the track, and has a high degree of authenticity in the simulation experiment. walking mechanism. [0004] The test crawler walking mechanism for the vehicle ground mechanics soil tank test bench of the present invention comprises a vehicle frame, and 4-8 road wheels are arranged side by side from left to right at the bottom end of the vehicle...
