Abstract: This invention relates to an endless traction band that is used to propel tracked vehicles [i.e., vehicles which use endless traction bands rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved traction band made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tension wheel. The inner surface of the endless traction band comprises a different lug configuration which allows for the endless traction band to be installed more efficiently on a tracked vehicle.

Abstract: This invention relates to endless tracks and systems used to propel tracked vehicles [i.e., vehicles which use endless tracks rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved split wheel design and installation process therefore. The track is made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tension wheel. A new step by step methodology allows the endless track to be installed and used more efficiently when the tension wheel or the drive sprocket is replaced by a split wheel.

Abstract: The endless track is made of a reinforced rubber material with longitudinally spaced and transversely disposed ridges or lugs. It is particularly well-adapted for recreational snowmobiles having a single track. The, ground-engaging side of the track features a tread pattern that is repeated uniformly or not over the entire length of the track. The tread pattern comprises a plurality of projecting traction lugs each an upper edge having which together delimit the general outline of a cross-sectional transversal traction lug profile when viewed along a longitudinal direction. The track is characterized in that the traction lug profile comprises a substantially flat central or interior section and two opposite exterior or lateral sections located on the sides of the interior section and that taper toward the exterior. Such track facilitates the steering capabilities of a snowmobile, particularly when the snowmobile is traveling on hard and abrasive surfaces. It also improves the durability of the track.

Abstract: The endless track is made of a reinforced rubber material with longitudinally spaced and transversely disposed ridges or lugs. It is particularly well-adapted for recreational snowmobiles having a single track. The ground-engaging side of the track features a tread pattern that is repeated uniformly or not over the entire length of the track. The tread pattern comprises a plurality of projecting traction lugs each having an upper edge. The internal side of the track features a plurality of protuberances called drive lugs which engage in the sprockets. These sprockets are driven by the snowmobile engine and transmit its power to the endless track. The braking power is also transmitted by the sprockets to the track. It is characterized in that the drive lugs have a pitch distance half of the pitch distance of the tread pattern therefore doubling the number of lugs engaged in the sprocket. Such tracks reduce noise and rolling resistance.

Abstract: The endless track is made of a reinforced rubber material with longitudinally spaced and transversely disposed ridges or lugs. It is particularly well-adapted for recreational snowmobiles having a single track. The track is characterized in that the rubber material of the central portion of the body has a hardness of between 75 and 90 duro A while the rubber material of the opposite band portions of the body has a hardness between 55 and 75 duro A. Such track facilitates the steering capabilities of a snowmobile, particularly when the snowmobile is traveling on hard and abrasive surfaces. It also improves the durability of the track.

Abstract: This invention relates to endless tracks and systems used to propel track-laying vehicles [i.e., vehicles which use endless tracks rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved rubber track design and system allowing the endless track to be driven more efficiently at highway speeds. The track is made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tensioning wheel, said track having a first exterior ground engaging surface and a second interior drive sprocket engaging surface, said track comprising: a carcass portion in which reinforcing means are embedded into said polymer; a plurality of tread lugs disposed on said first engaging surface; a plurality of drive lugs disposed on said second engaging surface and a plurality of drive horns disposed on said second engaging surface.

Abstract: A self-cleaning flexible track for use with vehicles suitable for travel over rough terrain, the track being adapted to be entrained by a drive wheel disposed on the vehicle, the track having opposed first and second lateral sides, an inward surface and an outward surface, track having a plurality of spaced apart paddles projecting from the interior surface adjacent each of the first and second lateral sides, the paddles have a body portion and a pedestal wherein the body portion is much wider than the pedestal, wherein the body portion and the pedestal of each of the paddles are configured and disposed to form an outlet therebetween, the outlet allowing the interior volume of the track and the exterior of the track to be in constant communication with each other.
