Shock-absorbing modular road wheel set with three-stage balanced suspension

Abstract

The invention discloses a shock-absorbing modular load wheel set with a three-stage balance suspension, and relates to a load wheel set of a rubber crawler walking device. The invention includes a first-level balance suspension, a first-level balance suspension rubber ball joint and two modular double-row road wheel assemblies. The invention adopts multiple groups of road wheels, which can carry heavy vehicles and make the grounding pressure of the rubber crawler running device more uniform; it has a three-stage balanced suspension structure, which can significantly improve the ride comfort and passability of the vehicle; the rubber ball hinge or The rubber bushing can greatly improve the shock absorption effect of the rubber crawler walking device; at the same time, the balance suspension at all levels can be modularized and assembled, which can realize quick loading and unloading, and is easy to use and maintain.

Description

technical field [0001] The invention relates to a load wheel set of a rubber crawler traveling device, which belongs to the technical field of crawler vehicles, in particular to a shock-absorbing modular load wheel set with a three-stage balance suspension. Background technique [0002] At present, the running gear of tracked vehicles can be divided into two types: steel track type and rubber track type. The crawler road wheel set is a key part of the running gear of the tracked vehicle. The track road wheel set rolls on the track, transfers the weight of the body to the ground through the track, and prevents the track from moving laterally relative to the frame. Correspondingly, the road wheel sets are also different for steel tracks and rubber tracks. [0003] Chinese patent CN102951219 A discloses a track-type skid steer loader roller damping device, which includes a roller and a stand, and also includes a shock absorber for connecting the rollers and the stand; The sup...

AI Technical Summary

Problems solved by technology

[0006] One is that the number of balance suspension stages of the road wheel system is small, basically no more than two stages, resulting in different loads on the tracks of different road wheels, causing uneven temperature rise, and also making the vehicle's ride comfort and passability poor;

[0007] The second is that the number of road wheels is relatively small, and two sets of four-row road wheels are basically used. The total number of road wheels does not exceed 8, and the ground pressure is unevenly distributed, which is not conducive to improving passability;

[0008] The third is that the connection between the road wheel set used in the road wheel train and the frame of the rubber crawler traveling device is complicated, and independent loading and unloading cannot be realized, which is not convenient for quick maintenance;

[0009] Fourth, when the balance suspension of the load wheel system is hinged with a bearing structure, the balance suspension does not have a buffering effect when swinging. When using rubber pads, the shock absorption effect of the balance suspension is poor, which reduces the service life of each component of the rubber crawler walking device , and the sealing lubrication is complicated, which increases the frequency and difficulty of maintenance
