Loading wheel chain assembly

Abstract

The invention relates to the technical field of vehicles, in particular to a loading wheel chain assembly which comprises loading wheels and loading wheel suspensions, the loading wheels are mounted on the loading wheel suspensions, and the loading wheel suspensions are sequentially connected in series and hinged to form the loading wheel chain assembly flexible in form. The loading wheel chain assembly can be used as a loading wheel and a track supporting wheel, and can guide a rubber track by limiting the transverse displacement (in the width direction of the track) of the rubber track, so that the situation of belt separation is avoided. Due to the flexible form of the loading wheel chain assembly body, the grounding part of the walking system can better conform to the topographic change, and the grounding area of the walking system can be conveniently adjusted.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, and in particular to a load-bearing wheel chain assembly. Background technique [0002] The road wheels of the current crawler traveling system are generally installed on the vehicle body through different suspensions, or multiple road wheels are installed on the same suspension, and there is no direct connection between the suspensions. The former makes the movements of multiple road wheels independent of each other, while the latter makes the movements of individual road wheels completely correlated. When driving on complex terrain, the former can make the vehicle have better ride comfort, but due to the lack of correlation between the road wheels, when the road wheels swing, it is easy to loosen the track and cause the track to fall off. The latter has poor ride comfort and passability. For example, a Chinese patent discloses a reconfigurable variant wheel that can realize wheel and ...

Problems solved by technology

In the above two patents, the structure and installation method of the cage (support frame) and the load wheel set (roller) are the same. The disadvantage of this structure is: because the load wheel set is evenly arranged in the circular arc range determined by the cage Inside, it is always in one form, and the wheel center positions of each road wheel can never be on the same straight line. In the track wheel form, a cage can only ensure that one or at most two road wheels in different positions on it are crushed on the track. The middle part and both sides of the grounding part are upturned, and the part in contact with the ground is not in a straight line. It is difficult for other road wheels to touch the track, resulting in concentrated load. On the one hand, it will lead to premature damage of the road wheels and reduce the service life. On the one hand, due to the uneven grounding pressure of the walking system, the passability and reliability are reduced
