A crawler wheel with adjustable ground contact area and elastic tightness

Abstract

The invention belongs to the technical field of vehicles and provides a contact area and tightness adjustable crawler wheel in order to achieve the functions of the contact area adjustment and the tightness adjustment of a rubber crawler and enable the vehicles to have high maneuverability and trafficability performance simultaneously. Through the contact area and tightness adjustable crawler wheel, the adjustment of different contact areas on the three road conditions such as highways, cross-country and extreme conditions can be achieved by controlling oil charge and oil discharge of a double-acting hydraulic cylinder in a contact area adjusting mechanism on the premise of ensuring original steering, braking, transmitting and other functions; through the control over a tension cylinder in a crawler tensioning mechanism, the tensioning and loosening of the rubber crawler can be achieved so that it can be guaranteed that the crawlers of the vehicles will not fall off in the running or steering process of the vehicles, and the road condition adaptive capacity of the vehicles are improved. The contact area and tightness adjustable crawler wheel has a certain military value and social and economic benefits.

Description

Technical field [0001] The invention belongs to the technical field of vehicles, and particularly relates to a track wheel with adjustable ground contact area and elasticity. Background technique [0002] With the changes in military missions and tasks, the use of military vehicles has become more and more extensive, and higher requirements have been placed on the regional adaptability and maneuverability of vehicles, which cannot be met by conventional wheeled or tracked vehicles. In particular, tracked vehicles are not suitable for the main direction of new forms of combat in the future. Wheeled vehicles are adapted to the above combat forms due to their maneuverability advantages. However, wheeled vehicles have higher ground pressure than tracked vehicles. When passing through extreme road conditions such as swamps and snow, they may sink and weaken their mobility. Combat capability. The wheeled vehicle walking system should continue to develop its high maneuverability, and ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned track wheels adopt a fixed structure, that is, the ground contact area of ​​the track cannot be adjusted. Therefore, while improving the vehicle passability, the mobility of the vehicle is greatly sacrificed, and the application in many occasions is limited.
