Multi-purpose vehicle provided with variable-diameter wheels and connecting rod type sliding sledges

Abstract

The invention discloses a multi-purpose vehicle where connecting rod type sliding sledges and variable-diameter wheels are installed. Besides a basic structure of an automobile, the multi-purpose vehicle further comprises the sliding sledges, rubber foot plates and elastic diameter-varying wheel stands. The sliding sledges are installed on two front wheels of the existing automobile, and the diameter-varying wheel stands are installed on a half shaft of the automobile. The elastic diameter-varying wheel stands rotates at a certain angle relative to a hub A and a hub C through a hub B and simultaneously drives an elastic diameter-varying part to rotate on the circumferential direction of the hub B, so that the elastic diameter-varying part is unfolded or folded, and accordingly wheel diameter variation of rear wheels of the automobile is achieved. By adopting combination of the sliding sledges and the diameter-varying wheel stands, the multi-purpose vehicle can improve passing ability on soft ground, reduces rolling resistance and improves driving force, the sliding sledges are used to support an automobile body in shallow water and foreshore areas, sinking of the automobile body is avoided, and the multi-purpose vehicle can run at a high speed on highways when the sliding sledges and the rear wheels are retracted to round wheels.

Description

[0001] divisional application [0002] For the present invention application, it is a divisional application to the original application number 201010245999.8, and the original application date is August 5, 2010. technical field [0003] The present invention relates to a multi-dwelling multi-modal vehicle, more particularly, to a multi-dwelling vehicle equipped with skids and variable diameter wheels. Background technique [0004] About 50% of the areas on the earth are conventional vehicles (vehicles equipped with wheels or crawler tracks) that cannot operate normally, such as deserts, tidal flats, grasslands, swamps, polar regions, Gobi, snow fields, etc., which greatly limit the range of human activities , the development of a multi-habitat vehicle mobile platform that can effectively operate in the above-mentioned regions is of great significance to science, military affairs, transportation, human life and business activities. Since the First World War, people have not...
