Damping device for thrust wheels of crawler-type skid-steer loader

Abstract

A damping device for thrust wheels of a crawler-type skid-steer loader comprises the thrust wheels, a rack and shock pads. The shock pads are used for connecting the thrust wheels and the rack, and each thrust wheel comprises a hinge, a hinge pin, a support and wheel bodies. The support comprises two side plates, a beam and a hinge ring, the two side plates and the beam are fixedly connected to form an H-shaped structure, and the hinge ring is fixed on the beam in the middle of the H-shaped structure. The wheel bodies are respectively and rotatably mounted at notch positions of two ends of the H-shaped structure, the hinge pin penetrates through the hinge and a through hole of the hinge ring on the support, and hinging of the hinge and the support is achieved. Limit blocks for limiting swinging angles of supports of the thrust wheels are arranged on side faces of the rack. The damping device has the advantages that the thrust wheels are large in the swinging angles and high in obstacle climbing ability, the damping device is fine in damping effect, simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to a shock absorbing and buffering device, in particular to a track type skid steer loader supporting wheel shock absorbing device. Background technique [0002] At present, the track rollers of the traditional track-type skid steer loader walking system are rigidly connected to the platform. When the vehicle works on uneven ground or the vehicle climbs over obstacles, it will cause a small number of rollers to bear the load of the whole machine. The weight of the roller will produce severe vibration and impact when walking, which will affect the service life of vehicle components and driving comfort, and the service life of the roller itself will also be greatly reduced. At the same time, due to the reduction of the ground contact area of ​​the crawler, the grip of the crawler is reduced, resulting in a decrease in traction; and because some of the rollers are separated from the chain rail, there is a risk of derailment of the cr...
