Abstract

A transverse bar for tracks of snow groomers is defined by a section bar, which extends in a direction, and is provided with an inner cavity, which extends through the section bar in the direction, is laterally open in the direction, and is at least partially filled with a water-repellent polymer filling material.

First claim

The invention claimed is:

1. A snow groomer track transverse bar comprising:
a section bar of an elongated shape that defines an inner cavity that extends through the section bar in a first direction, is laterally open in the first direction, and is at least partially filled with a water-repellent polymer filling material, and is delimited by an outer surface including a fixing portion configured to be fixed to a belt of a track of a snow groomer.

2. The snow groomer track transverse bar of claim 1 , wherein the filling material comprises a low-density water-repellent polymer material.

3. The snow groomer track transverse bar of claim 1 , wherein the fixing portion is configured to be fixed to the belt by a fixing device configured to be fitted in the inner cavity, and the filling material locks the fixing device inside the inner cavity in at least one of: the first direction and a second direction that is perpendicular to the fixing portion.

4. The snow groomer track transverse bar of claim 3 , wherein the fixing device comprises:
an inner plate in the inner cavity;
an outer plate on an opposite side of the section bar relative to the belt;
a fastening screw that extends through the inner plate, the section bar, the belt, and the outer plate; and
a fastening nut screwed onto the fastening screw.

5. The snow groomer track transverse bar of claim 4 , wherein the filling material partially fills the inner cavity to define, together with the section bar, a feed channel to move the inner plate along the inner cavity.

6. The snow groomer track transverse bar of claim 5 , wherein the filling material is arranged in the inner cavity to lock the inner plate in the second direction that is perpendicular to the fixing portion.

7. The snow groomer track transverse bar of claim 4 , wherein the filling material locks the inner plate in the first direction.

8. The snow groomer track transverse bar of claim 1 , further comprising two closing caps configured to close free ends of the section bar.

9. A snow groomer comprising:
a support frame;
a driver cabin fitted on the support frame; and
two tracks fitted on opposite sides of the support frame, each track comprising:
a plurality of parallel belts, and
a plurality of transverse bars fixed to the belts, each transverse bar comprising a section bar of an elongated shape that defines an inner cavity that extends through the section bar in a first direction, is laterally open in the first direction, and is at least partially filled with a water-repellent polymer filling material, and is delimited by an outer surface including a fixing portion configured to be fixed to at least one of the belts.
