Real-time adjustment structure of suspension rigidity of hydraulic front guide wheel

Abstract

The invention discloses a real-time adjustment structure of suspension rigidity of a hydraulic front guide wheel. The real-time adjustment structure is characterized in that a load-bearing wheel is arranged below the vehicle frame and is rotatably mounted on the vehicle frame; a drive cylinder is arranged above the vehicle frame and one end is rotatably mounted on the vehicle frame; a telescopic shaft is arranged on the drive cylinder; a guide wheel is rotatably mounted at one end of the telescopic shaft away from the first shaft through a third shaft; and a track belt sequentially bypasses the guide wheel and the load-bearing wheel. The real-time adjustment structure of the suspension rigidity of the hydraulic front guide wheel has the advantages of being reasonable in structure setting,having no demand for stopping the current operation, having no demand for adjusting the tightness of the track through a complex disassembling process, and changing the position of the front guide wheel, relative to the vehicle frame and the suspension rigidity relative to the vehicle body in real time by changing the position of the front guide wheel relative to the vehicle body by the drive cylinder, so as to improve the driving ability of a crawler type agricultural vehicle.

Description

technical field [0001] The invention relates to the technical field of agricultural crawler vehicles, in particular to a structure for real-time adjustment of the suspension stiffness of a hydraulic front guide wheel. Background technique [0002] Tracked agricultural vehicles have the advantages of low pressure per unit area on the soil and good adhesion to the soil (not easy to slip). They have better passing performance in wet and soft soils and high traction efficiency, and are especially suitable for agricultural complex soils. work in the environment. [0003] The front guide wheel of the track is a driven wheel, which is used to induce and support the track, and adjust the tightness of the track together with the track adjuster. The suspension stiffness of the front guide wheel has a great influence on the driving ability, passability and smoothness of the tracked agricultural vehicle in the complex agricultural soil environment. [0004] At present, the connection ...

AI Technical Summary

Problems solved by technology

If a suspension with a high rigidity is installed, the impact from the ground will be very large, the vehicle body will vibrate violently, the occupants will be easily fatigued during continuous driving, and parts will be worn out. When operating in poor ground environments such as reed fields, problems such as slipping and chain drop will occur, which will affect the driving ability and passability of tracked agricultural vehicles in such poor ground environments
