Test trolley for vehicle terramechanics soil bin test bed

Abstract

The invention discloses a test trolley for a vehicle terramechanics soil bin test bed, which comprises an underframe. The top part of the underframe is fixed with a box body; a front guide rail is arranged at the front end of the top part of the box body along a horizontal direction; a rear guide rail is arranged at the rear end of the top part of the box body along a horizontal direction; the left side of the box body is provided with an electric dynamometer; the base of the electric dynamometer is arranged on the underframe; the rotating shaft of the electric dynamometer is connected with a power input shaft of a power-measuring speed reducer via a coupler; the power output shaft of the power-measuring speed reducer is sleeved with a speed reducer driving sprocket; and the speed reducer driving sprocket is in transmission connected with a speed reducer driven sprocket via a transmission chain. According to the test trolley for the vehicle terramechanics soil bin test bed disclosed by the invention, driving resistance states of wheels of various structural sizes in various soil conditions can be measured, data obtained through the test are precious, various necessary parameters can be provided for vehicle wheel optimization design, and the vehicle wheel performance is optimized.

Description

technical field [0001] The invention relates to a test platform vehicle for a vehicle ground mechanics soil tank test platform. Background technique [0002] The optimal design of the vehicle requires a variety of experimental parameters. For example, it is necessary to measure the driving resistance of the wheel under specific soil conditions. However, directly collecting relevant data through the actual running vehicle is not only low in work efficiency, but also requires a large investment. And it is also difficult to operate all the various roads. For this reason, people have designed soil tank test rigs to test the various mechanical properties of wheels, but the test rigs of existing soil tank test rigs can only be tested for wheels with specific structural dimensions. Wheels of different structural sizes need to be manufactured separately, and each soil tank test bench cannot adapt to wheels of various structural sizes, and the existing soil tank test bench is subjec...

Problems solved by technology

[0002] The optimal design of the vehicle requires a variety of experimental parameters. For example, it is necessary to measure the driving resistance of the wheel under specific soil conditions. However, directly collecting relevant data through the actual running vehicle is not only low in work efficiency, but also requires a large investment. Moreover, it is also difficult to operate all kinds of roads

For this reason, people have designed soil tank test rigs to test the various mechanical properties of wheels, but the test rigs of existing soil tank test rigs can only be tested for wheels with specific structural dimensions. Wheels of different structural sizes need to be manufactured separately, and each soil tank test bench cannot adapt to wheels of various structural sizes, and the existing soil tank test bench is subject to its own power device during the test due to its unreasonable design structure. The interference is large, resulting in low accuracy of the data obtained in the experiment, which will affect the optimal design of the vehicle wheel
