A driving system for a tracked vehicle, in particular a tracked vehicle used for the preparation of ski slopes, features a driving wheel rotatable about a first axis of rotation; an idle wheel rotatable about a second axis of rotation parallel to the first axis of rotation; and a track looped around the driving wheel and the idle wheel, and comprising a plurality of strips made of elastomeric material, and a plurality of metal grousers, fixed to the strips; wherein at least one strip has at least one continuous toothed strip, which extends along the inner face of the strip and is configured to engage with the driving wheel.

Driving wheel and driving system for a tracked vehicle

A cross-link for tracks of snow groomers, the cross-link comprising a section bar, which has an elongated shape, extends in a first direction, is limited by an outer surface and comprises a portion for fixing to at least one belt of a track of a snow groomer, and it is provided with an inner cavity, which extends through the section bar in the first direction, and is open at the side in the first direction; wherein the inner cavity is filled, at least in part, with a filling material comprising metal foam, and in certain embodiments, the inner cavity is completely filled with the filling material.

Cross-link for tracks of snow groomers

A belt for tracked vehicles suitable for being driven in a closed loop between a front wheel and a rear wheel of the vehicle along a longitudinal direction and for supporting a plurality of transverse bars adapted to stick in the ground along at least a portion of the lower run of the belt loop; the belt comprising a fabric multi-layer internal structure embedded in vulcanized rubber, wherein at least a portion of the fabric fiber of at least one layer is made of aramid.

Belt for tracked vehicles

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.

Transverse bar for tracks of snow groomers

A crawler vehicle drive system, in particular for a crawler vehicle configured to groom ski slopes, having: a drive wheel rotating about a first rotation axis; an idle wheel rotating about a second rotation axis parallel to the first rotation axis); and a track looped around the drive wheel and the idle wheel, and comprising a plurality of belts made of an elastomeric material and a plurality of metal grousers fixed to the belt; wherein at least one belt has at least one continuous toothed strip extending along the inner face of the belt and configured to mesh with the drive wheel.

Crawler vehicle drive system and crawler vehicle comprising such a drive system

A supporting device for a crawler vehicle configured to groom ski slopes, is mounted between a rear wheel and a front wheel, resting along the inside of a traction portion of the track, and has a plurality of rollers much smaller in diameter than the rear wheel; a belt looped around the rollers; and a structure configured to support the rollers and to push the rollers and the belt against the inside of the traction portion of the track.
