Title:
LOW-LOSS CRAWLER BELT WITH TRANSVERSE MOVING ROLLERS
Document Type and Number:
WIPO Patent Application WO/2021/098027
Kind Code:
A1
Abstract:
Disclosed is a low-loss crawler belt with transverse moving rollers (b), wherein a surface of each crawler belt chain plate (a) that is in contact with the road ground is provided with a transverse moving roller (b) enabling the chain plate (a) to move transversely, so as to form a chain plate unit group (5), and a plurality of identical chain plate unit groups (5) are connected to form a closed crawler belt loop chain, which is driven by a chain wheel (4) to operate; and axial directions of the transverse moving rollers (b) are consistent with an advancing direction of the crawler belt, the transverse moving rollers (b) play the role of longitudinally grabbing the ground when a machine moves along a straight line, and the transverse moving rollers (b) move transversely while grabbing the ground when the machine turns and moves or steers in situ, such that damage to a road surface is avoided, abrasion of the chain plate (a) itself is also avoided, and compared with a traditional crawler belt, the loss of the present crawler belt is low.
