Abstract

A cross-link for a track of a tracked vehicle, in particular a snow groomer, configured to advance along delicate ground, and which extends along a designated plane and has a mounting member comprising a wall configured for being arranged in contact with the delicate ground; a blade, which protrudes from the wall, is fixed to the wall and has a free edge, wherein the wall and the blade are configured so as to define two support surfaces extending on opposite sides of the blade to enable the sinking of the blade into the delicate ground and prevent the sinking of the mounting member.

First claim

The invention is claimed as follows:

1. A cross-link for a track of a tracked vehicle configured to advance along delicate ground, the cross-link extending parallel to a designated plane and comprising:
a mounting member comprising a wall configured for being arranged in contact with the delicate ground; and
a blade having a free edge and being fixed to the wall, wherein the wall and the blade are configured to define two support surfaces extending on opposite sides of the blade, the two support surfaces enable a sinking of the blade into the delicate ground and prevent a sinking of the mounting member into the delicate ground, wherein the two support surfaces each have a same area and a same width such that the blade protrudes a distance from the wall which is less than twice the width of either of the two support surfaces, the distance that the blade protrudes from the wall being within a range of thirteen millimeters to seventeen millimeters.

2. The cross-link of claim 1 , wherein the distance the blade protrudes from the wall is greater than the width of either of the two support surfaces.

3. The cross-link of claim 1 , wherein the blade extends along the designated plane and the two support surfaces are symmetrical with respect to the designated plane.

4. The cross-link of claim 1 , wherein the free edge of the blade is indented.

5. The cross-link of claim 1 , wherein the mounting member has an opening configured to house a fastening member.

6. The cross-link of claim 1 , wherein the mounting member and the blade are assembled with one another, the mounting member has a seat configured to house the blade and the mounting member is extruded.

7. The cross-link of claim 1 , wherein the mounting member and the blade comprise a single piece.

8. The cross-link of claim 7 , wherein the mounting member and the blade are extruded as the single piece.

9. The cross-link of claim 7 , wherein the single piece of the mounting member and the blade is made by folding and welding a metal blank.

10. The cross-link of claim 1 , wherein the tracked vehicle comprises a snow groomer.

11. The cross-link of claim 1 , wherein the two support surfaces are each perpendicular to the blade.

12. A track for a tracked vehicle, the track comprising:
a plurality of continuous-loop rubber belts, and
a plurality of cross-links, each of which is mounted on the belts transversely to the belts and each of which comprises:
a mounting member comprising a wall configured for being arranged in contact with delicate ground, and
a blade having a free edge and being fixed to the wall, wherein the wall and the blade are configured to define two support surfaces extending on opposite sides of the blade, the two support surfaces enable a sinking of the blade into the delicate ground and prevent a sinking of the mounting member into the delicate ground, wherein the two support surfaces each have a same area and a same width such that the blade protrudes a distance from the wall which is less than twice the width of either of the two support surfaces, the distance that the blade protrudes from the wall being within a range of thirteen millimeters to seventeen millimeters.

13. The track of claim 12 , wherein the tracked vehicle comprises a snow groomer.

14. The track of claim 12 , wherein for each of the plurality of cross-links, the two supports surfaces of that cross-link are each perpendicular to the blade of that cross-link.
