Problems solved by technology

[0002] Tracked engineering vehicles often work on uneven roads. The tracked traveling system, the entire body, and the driver will be subject to severe vibration shocks. The vibration shocks mainly come from the driving sprocket, because the driving sprocket is connected between the traveling system and the final drive. The hub is subject to severe vibration and impact. For the driving wheel, it will accelerate the wear of the teeth of the driving wheel. The body will be subjected to severe vibration transmission, which will hinder walking and accelerate the fatigue life of body parts
[0003] Most researchers reduce the wearing and tearing of driving wheel tooth and crawler belt from improving sprocket mesh tooth profile, as CN103832495 A proposes a kind of driving wheel tooth tooth profile that is applied to crawler engineering vehicle, makes original Optimized improvements have been made to reduce the wear of the sprocket mesh, but although the above improvements can reduce the wear of the gears, the effect is not significant

Abstract

The invention is aimed at providing a damping driving wheel. Wheel teeth can be conveniently replaced, and the vibration of the driving wheel can be controlled. The damping driving wheel comprises anouter wheel hub, a middle frame, an inner wheel, the wheel teeth, a damping pipe, a U-shaped connector and a quick-detach connecting rod. A circumferential groove is formed in the outer ring arc-shaped surface of the outer wheel hub. A middle frame circular positioning groove is formed in the inner ring arc-shaped surface of the outer wheel hub and used for positioning and installing the middle frame. Protruding teeth are arranged on the outer ring arc-shaped surface of the inner wheel at equal intervals and correspond to a pipe base on the middle frame in position. Each wheel tooth is composed of a wheel tooth body and a wheel tooth base. The inner wheel, the outer wheel and the middle frame are fixed into a whole through the U-shaped connector and the quick-detach connecting rod. By means of the driving wheel, the stable and safe working of a whole crawler working system can be ensured, and the driving wheel is particularly suitable for a medium-large-sized crawler type bulldozer.

technical field [0001] The invention belongs to the field of driving wheels, in particular to a modular vibration-damping driving wheel. Background technique [0002] Tracked engineering vehicles often work on uneven roads. The tracked traveling system, the entire body, and the driver will be subject to severe vibration shocks. The vibration shocks mainly come from the driving sprocket, because the driving sprocket is connected between the traveling system and the final drive. The hub is subject to severe vibration and impact. For the driving wheel, it will accelerate the wear of the teeth of the driving wheel. The body will be subjected to severe vibration transmission, which will hinder walking and accelerate the fatigue life of body parts.
