Caterpillar band system of movable heavy engineering machine and engineering vehicle

Abstract

The invention discloses a caterpillar band system of a movable heavy engineering machine and an engineering vehicle. The caterpillar band system comprises a caterpillar band, a driving wheel, a guiding wheel, multiple supporting wheels and multiple support chain wheels; the caterpillar band is composed of multiple caterpillar band plates which are sequentially connected and form a closed loop; thedriving wheel is arranged in the caterpillar band and located at the rear end of the caterpillar band; the guiding wheel is arranged in the caterpillar band and located at the front end of the caterpillar band; the supporting wheels are arranged in the caterpillar band at intervals and located at the lower portions between the driving wheel and the guiding wheel; the support chain wheels are arranged in the caterpillar band at intervals, and located at the upper portions between the driving wheel and the guiding wheel. By means of the system, the raceway face contact condition between the caterpillar band plates and the supporting wheels, the guiding wheel and the support chain wheels is greatly optimized, the caterpillar band can provide continuous support for the supporting wheels, thecontact stress is smaller, the overall casting manufacturability is better, the overall weight is lower, and the flexibility and maneuverability of the complete machine are conveniently improved on the condition that the reliability is guaranteed.

Description

technical field [0001] The invention relates to a chassis part for a mobile machine, in particular to a crawler system of a mobile heavy engineering machine. Background technique [0002] Heavy-duty construction machinery used in mining, construction and other industries often needs to traverse soft or loose mud or other materials, or even travel on steep slopes during the construction process. The climbing ability, running stability and reliability of the walking system, etc. Factors are very demanding. Pneumatic tires or pneumatic wheels are easy to get stuck or slip, and the crawler travel system has become the first choice for this type of construction machinery. The crawler system is the core component and is the carrier that converts the driving force of the travel motor into the travel power of the whole machine. The smooth meshing transmission between the crawler belt and the driving wheel, and the reasonable cooperation with the supporting rollers are the key facto...

AI Technical Summary

Problems solved by technology

[0003] At present, the track system for heavy construction machinery often adopts the traditional structure, and there are problems such as spalling, falling off, and cracking caused by the large contact stress of the raceway surface of the track shoe, and the lack of rigidity and strength of the driving wheel leads to the fracture of the driving tooth, etc.
