ENDLESS TRACK

Document Type and Number:

WIPO Patent Application WO/2015/159896

Kind Code:

A1

Abstract:

This rubber endless track with a specified rotation direction is provided with an endless track body, rubber projections protruding from the inner peripheral surface, and multiple lugs protruding from the outer peripheral surface. Viewed from the outer periphery of the endless track, the lugs are alternately arranged in the endless track circumferential direction so as to be distributed on one side and the other side of a center line in the endless track width direction, and extend from the inside end towards the outside in the endless track width direction in the opposite direction to the endless track rotation direction, obliquely to the endless track circumferential direction. Outwards from the center line in the endless track width direction, on the acute angle side, the angle relative to the endless track circumferential direction becomes larger. The lugs are arranged in positions such that the inside ends adjacent in the endless track width direction each overlaps with one rubber projection and are separated in the endless track width direction, and the inside ends adjacent in the endless track width direction overlap when viewed from the endless track width direction.
