The invention provides a testing crawler belt or a wheel drive device used for a soil bin test bench. The testing crawler belt or a wheel drive device comprises a motor installed on the right end of a support vehicle frame. A rotating shaft of the motor is in transmission connection with a power input shaft of a speed reducer. A housing of the speed reducer is installed on the support vehicle frame. The power output shaft of the speed reducer is sleeved by an active chain wheel of the speed reducer. The active chain wheel of the speed reducer is in transmission connection with an active chain wheel of a primary duplex chain wheel through a primary transmission chain. Circumferential surfaces of the active chain wheel of the speed reducer and the primary duplex chain wheel are arranged in left and right vertical directions. The invention aims to provides the testing crawler belt or the wheel drive device used for the soil bin test bench, the testing crawler belt or the wheel drive device can be used for measuring stress states of crawler belts or wheels of different structure sizes, and the interference to a pull-push sensor is small, so that the practical environment state can be simulated more really, and the authenticity of a simulation experiment is improved.
Description
technical field [0001] The invention relates to a test crawler or wheel drive device for a soil tank test bench. Background technique [0002] The driving device used in the existing soil tank test bench cannot be used in the soil tank test bench applicable to wheels of various structural sizes, and the driving device of the existing soil tank test bench is unreasonable due to its unreasonable design structure, resulting in its own The interference of the power unit on the tension and pressure sensors is large, resulting in low accuracy of the data obtained in the experiment, which will affect the optimal design of the vehicle wheels. Contents of the invention [0003] The purpose of the present invention is to provide a method that can be applied to various structural sizes of crawler tracks or wheels to measure the stress state, which has little interference with tension and pressure sensors, thereby more realistically simulating the actual environmental state, and impro...
