Abstract
A track for traction of a vehicle (e.g., a compact track loader or other construction vehicle) which may be designed to enhance a resistance to wear of the track, including a resistance to cracking of elastomeric material of the track and a resistance to delamination of the elastomeric material of the track from cores at least partially embedded in the elastomeric material of the track.
Claims34
A track for traction of a vehicle, the track being mountable around a plurality of wheels that includes a plurality of roller wheels for rolling on a bottom run of the track along a rolling path of the track, the track comprising:
- a ground-engaging outer side;
- an inner side opposite to the ground-engaging outer side;
- elastomeric material allowing the track to flex around the wheels;
- a plurality of cores at least partially embedded in the elastomeric material, distributed in a longitudinal direction of the track, extending transversally to the longitudinal direction of the track, and each comprising a guide projection on the inner side of the track for contacting the roller wheels to guide the track;
- and
- a cracking inhibitor disposed along the rolling path, overlapping with one of the guide projections in the longitudinal direction and in a widthwise direction of the track, and configured to inhibit cracking of the elastomeric material at the rolling path, wherein
- the cracking inhibitor has a bottom surface with a height that varies, and
- the height of the bottom surface is greater at a first portion of the cracking inhibitor between the guide projection and an outer lateral edge of the rolling path in a widthwise direction of the track than a second portion of the track aligned with the guide projection in the widthwise direction of the track.

- and
- a cracking inhibitor disposed along the rolling path, overlapping with one of the guide projections in the longitudinal direction and in a widthwise direction of the track, and configured to inhibit cracking of the elastomeric material at the rolling path, wherein
- the cracking inhibitor has a bottom surface with a depth that varies, and
- the depth of the bottom surface is greater at a first portion of the cracking inhibitor between the guide projection and an outer lateral edge of the rolling path in a widthwise direction of the track than a second portion of the cracking inhibitor aligned with the guide projection in the widthwise direction of the track.

- and
- a plurality of crack-inhibiting elements spaced apart from one another in the longitudinal direction of the track, disposed between respective ones of the cores in the longitudinal direction of the track, and configured to inhibit cracking of the elastomeric material at the rolling path, wherein
- the plurality of crack-inhibiting elements each have a bottom surface with a depth that varies, and
- the depth of the bottom surface is greater at a first portion of the crack-inhibiting element between the guide projection and an outer lateral edge of the rolling path in a widthwise direction of the track than a second portion of the crack-inhibiting element aligned with the guide projection in the widthwise direction of the track.
