Abstract
A track for a snow groomer having a plurality of grousers spaced apart, extending crosswise to the traveling direction of the track, and each having a grip portion configured to grip the terrain, and a blunt edge opposite the grip portion. A chain is connected to the blunt edges of the grousers so as to be engaged, in use, by a drive sprocket of a snow groomer.
Claims16
A snow groomer track comprising:
- a plurality of spaced apart grousers extending crosswise to a traveling direction of the snow groomer track, each grouser having:
- a grip portion configured to grip a terrain, and
- a blunt edge opposite the grip portion;
- a chain connected to the blunt edges of the grousers, said chain configured to be engaged, in use, by a drive sprocket of a snow groomer;
- and
- a plurality of elastically deformable connectors configured to connect the chain to the grousers to permit controlled relative rotation of the grousers with respect to the chain in a plane crosswise to the traveling direction of the snow groomer track.

A snow groomer track comprising:
- a plurality of spaced apart grousers having a plurality of respective longitudinal cavities and extending crosswise to a traveling direction of the snow groomer track, each grouser having:
- a grip portion configured to grip a terrain, and
- a blunt edge opposite the grip portion;
- a chain connected to the blunt edges of the grousers, said chain configured to be engaged, in use, by a drive sprocket of a snow groomer;
- and
- a plurality of elastically deformable connectors configured to connect the chain to the grousers to permit controlled relative rotation of the grousers with respect to the chain in a plane crosswise to the traveling direction of the snow groomer track, wherein the elastically deformable connectors include:
- a plurality of threaded pins projecting from the blunt edges of respective grousers and inserted through a plurality of respective fastening holes in the chain, the threaded pins of each grouser being carried by a respective strip housed inside the longitudinal cavity of the grouser, and being inserted through at least one opening formed in the blunt edge of the grouser,
- a plurality of nuts fitted to respective threaded pins, and
- a plurality of first bushes of resilient material, housed in the fastening holes, about the respective threaded pins.

A snow groomer track comprising:
- a plurality of spaced apart grousers extending crosswise to a traveling direction of the snow groomer track, each grouser having:
- a grip portion configured to grip a terrain, and
- a blunt edge opposite the grip portion;
- and
- a chain connected to the blunt edges of the grousers, said chain including a plurality of links, and a plurality of hinge connectors configured to hinge connect pairs of adjacent links about a respective hinge axes crosswise to the traveling direction of the snow groomer track, said hinge connectors are elastically deformable to permit controlled relative rotation of any two adjacent links about a plurality of axes not coincident with the respective hinge axis of said two adjacent links and each of the hinge connectors including a connecting pin between pairs of adjacent links in the chain and a hinge bush of resilient material inserted between each link in the chain and the connecting pin, said chain configured to be engaged, in use, by a drive sprocket of a snow groomer.
