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

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] see figure 1 , Figure 7 , a shock-absorbing modular road wheel set with a three-stage balanced suspension, including a primary balanced suspension 3, a primary balanced suspension rubber ball joint 2, and two modular double-row road wheel assemblies; the The double-row road wheel assembly consists of two single-row road wheel assemblies, a secondary balance suspension 4, and a secondary balance suspension rubber bush 6; the single-row road wheel assembly consists of two road wheels, A three-stage balance suspension 5 and a three-stage balance suspension rubber bushing 7 are formed.

[0033] see figure 1 , in order to better illustrate the content of the present invention, it is agreed that the transverse direction is the direction of the road wheel axle, and the direction perpendicular to the road wheel axle and forming a h...

Abstract

The invention discloses a damping modularized load bearing wheel set with three stages of balanced suspensions, and relates to a load bearing wheel set of a rubber belt track walking device. The damping modularized load bearing wheel set comprises the first-stage balanced suspension, a first-stage balanced suspension rubber spherical hinge and two modularized biserial load bearing wheel assemblies. Multiple sets of load bearing wheels are adopted, a heavy vehicle can be borne, and the grounding specific pressure of the rubber belt track walking device can be more even. The three-stage balanced suspension structure is arranged, and the smoothness and trafficability characteristics of a vehicle in the running process can be improved obviously. The rubber spherical hinge or a rubber bushing is adopted, and the damping effect of the rubber belt track walking device can be improved greatly. Meanwhile, the balanced suspensions of all the stages can be assembled in a modularized mode, fast assembling and disassembling can be achieved, use and repair are convenient, and maintenance is facilitated.

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...
