摘要

A rubber crawler (1) for a tracked vehicle comprising an endless rubber belt body (5) which is provided to revolve around a first and second member which are spaced from each other, the rubber crawler (1) being subject to bending when revolving around the members and being provided at its outer peripheral face (49) with a plurality of lugs (2) which protrude from the belt body (5), at least one lug (2) comprising a tread surface (4) and at least one upright sidewall (3) extending from the tread surface (4) to the rubber belt body (5) along a first direction (8) which transverses the length direction (7) of the rubber belt body (5), the tread surface (4) of subsequent lugs (2) being provided to create a running surface (6) for the crawler (1), characterised in that the upright sidewall (3) comprises at least one groove (10, 20, 30) which extends along at least part of the upright sidewall (3) along a second direction (9) which transverses the length direction (7) of the rubber belt body (5) and in that the lug (2) is at least partly made of a material (40) which is deformable at the position of the groove (10, 20, 30) when subjected to the bending to facilitate removal of soil material contained in the groove (10, 20, 30).
