Embodiment Construction

[0035] refer to figure 1 , as a whole, reference numeral 1 designates a tracked vehicle for clearing ski slopes and designed to move in a forward direction D1. A tracked vehicle 1 comprises a frame 2; two drive systems 3 ( figure 1 only one shown in ); the cabin 4; and the engine 5. Each drive system 3 includes a drive wheel 6; an idler wheel 7;

[0036] Each drive wheel 6 corresponds to a rear wheel of the tracked vehicle 1 , rotates about an axis of rotation A1 , and is driven by a preferably hydraulic or electric actuator, not shown in the figures.

[0037] Each idler wheel 7 corresponds to a front wheel of the tracked vehicle 1, rotates about an axis of rotation A2 parallel to the axis of rotation A1, and passes through the frame 2 in a selectively movable manner in two directions parallel to the forward direction D1 support to provide proper tensioning of the tracks 8 under all operating conditions.

[0038] The track 8 comprises an upper section and a lower section a...

Abstract

A crawler vehicle drive system, in particular for a crawler vehicle for grooming ski slopes, having: a drive wheel (6) rotating about a first rotation axis (A1); an idle wheel (7) rotating about a second rotation axis (A2) parallel to the first rotation axis (A1); and a track (8) looped around the drive wheel (6) and the idle wheel (7), and comprising a plurality of belts (17, 18) made of an elastomeric material and a plurality of metal grousers (16) fixed to the belt (17, 18); wherein at least one belt (18) has at least one continuous toothed strip (19) extending along the inner face of the belt (18) and designed to mesh with the drive wheel (6).

Description

technical field [0001] The present invention relates to a drive system for tracked vehicles, in particular tracked vehicles for clearing ski slopes. Background technique [0002] Typically, a drive system for a tracked vehicle of the type described above includes a drive wheel rotating about a first axis of rotation; an idler wheel rotating about a second axis of rotation parallel to the axis of rotation; and a wheel surrounding the drive wheel and the idler wheel. track. The track comprises a plurality of belts made of elastomeric material and a plurality of transverse metal elements fastened to the belts and distributed evenly along the track. The drive wheel has a sprocket and is designed to mesh with the transverse element. A drive system of the above-mentioned type is described in patent application DE 103 20523 A1. [0003] According to an alternative form described in patent application EP 2,285,651, the drive system comprises a chain connected to the transverse el...
