CN-114802505-B - Weight bearing wheel chain assembly

Abstract

The invention relates to the technical field of vehicles, in particular to a weight-bearing wheel chain assembly, which comprises a weight-bearing wheel and a weight-bearing wheel suspension, wherein the weight-bearing wheel is arranged on the weight-bearing wheel suspension, and the weight-bearing wheel suspension is sequentially hinged in series to form the weight-bearing wheel chain assembly with flexible shape. The bogie chain assembly can be used as a bogie or a riding wheel, and can also guide the rubber crawler by limiting the transverse displacement of the rubber crawler (along the width direction of the crawler), so that the occurrence of the belt-disengaging condition is avoided. The flexible form of the weight wheel chain assembly can enable the grounding part of the running system to better conform to the change of the terrain, and is convenient for adjusting the grounding area of the running system.

Description

Weight bearing wheel chain assembly Technical Field The invention relates to the technical field of vehicles, in particular to a weight bearing wheel chain assembly. Background The bogie wheels of the current crawler traveling system are generally mounted on a vehicle body through different suspensions, or a plurality of bogie wheels are mounted on the same suspension, and the suspensions are not directly connected. The former makes the movement of a plurality of bogie wheels independent of each other, and the latter makes the movement of each bogie wheel completely correlated. When the vehicle runs on complex terrain, the vehicle has better smoothness, but due to the lack of correlation between the bogie wheels, the crawler belt is easy to loosen to cause the belt to be taken off when the bogie wheels swing. The latter has poor smoothness and trafficability, for example, china patent discloses a reconfigurable variant wheel capable of realizing wheel-track switching, and the application number is 201922303041.9, and the retainer assembly in the application comprises a retainer, a bearing wheel group, a second fixed wheel shaft, a middle beam and a locking block, wherein the retainer is of an arc-shaped structure with a certain angle, and one end of the retainer is hinged with a fixed support or a movable support. The second fixed wheel axle is fixedly connected with the retainer, the bearing wheel in the bearing wheel group is sleeved on the second fixed wheel axle, and for example, china patent discloses a deformable tire, the application number of which is 202011010683.0, wherein the support frame comprises two support plates and a plurality of rollers, two ends of the plurality of rollers are respectively and rotatably connected with the two support plates, the connecting rod is rotatably connected with one support plate, the rollers are abutted with the crawler belt, and the rollers are in arc arrangement. In the two patents, the structures and the installation modes of the retainer (supporting frame) and the weight wheel sets (rollers) are the same, and the structure has the defects that the weight wheel sets are uniformly arranged in the circumferential arc range determined by the retainer and always in a form, the wheel center positions of the weight wheels cannot be always in the same straight line, when in the form of the crawler wheels, one retainer only can ensure that one or at most two weight wheels in different positions are rolled onto the crawler belt, the middle part and the two sides of the grounding part are upturned, the part contacted with the ground is not in a straight line, and other weight wheels are difficult to contact with the crawler belt, so that the load is concentrated, on one hand, the premature damage of the weight wheels and the like is caused, the service life is reduced, and on the other hand, the grounding pressure of the walking system is uneven, and the passing performance and the reliability are reduced. Disclosure of Invention The invention aims to overcome the defects of the prior art and provide a weight bearing wheel chain assembly.
