摘要:
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.

A stud mount for detachably mounting a traction stud to a snowmobile track assembly including an endless drive belt having at least one laterally extending reinforcing rod embedded in the drive belt. At least one stud mount is secured about the reinforcing rod by way of a mounting head and is opened to the ground-engaging side of the track to receive a traction stud. One or more stabilizing arms project laterally from the mounting head and are adapted embedded in the endless drive belt to provide lateral stability to the stud mounts under torque load.

An endless track for use with a vehicle, including a primary track section and at least one paddle is provided. The primary track section includes an upper surface, a lower surface, a first outer side and a second outer side. The paddle includes a first end and a second end, where the first end is operatively connected to the primary track section adjacent one of the sides. The paddle is non-perpendicular with respect to the primary track section such that the second end of the paddle is positioned outwardly away from the primary track section.

A tandem track system and method provides for safe withdrawal of a tracked vehicle if either of the main tracks becomes separated. The tracked vehicle has a main track longitudinally extending in a closed endless main loop on opposite sides and engaging a separate main drive sprocket assembly, extending under roadwheels to a main drive idler wheel, and back to the main drive-sprocket assembly in the main loop. The tandem drive system has a secondary track engaging each main drive-sprocket assembly and extending forward along the track vehicle from each main drive-sprocket assembly under only an aft-most fractional portion of the roadwheels. The secondary track is configured as a closed endless secondary loop inside of the main loop of each main track whereby each secondary track can transfer rotary power to move the tracked vehicle to safety.

An elastic track shoe is provided wherein loosening of bolts is prevented by use of a rigid core bar and the thickness of an elastic body subjected to a load can be increased irrespective of grousers. To this end, the core bar is integrally formed by casting, forging or precutting, a ground engaging side of the core bar is covered with the elastic body, and a portion of the core bar defined by projection of a ground engaging face of the elastic body is divided into two parts.

In a track with a rotatable bushing which is brought into engagement with a sprocket of a track-type vehicle, it is intended that strength is enhanced rationally by link functionality sharing and by combination of such assigned functional tasks for achieving further improvements in rotatable bushing function. To this end, a track link comprises a combination of an external link and an internal link; a coupler pin hole is provided through the external link; a bushing hole is provided through the internal link, and the thickness dimension of a bushing hole formation part of the internal link is made greater than that of a coupler pin formation part of the external link.

This invention is to suppress repeated striking noises as generated by a crawler belt (29) when taken up onto a drive sprocket (25) in a polygonally bent shape. A crawler belt support block (34) is fixedly mounted on top of an upper reinforcing plate (19) of a bracket (15) on the side of the drive sprocket. The crawler belt support block (34) includes a skid block (36) with a crawler belt sliding surface (36B) to be held in sliding contact with lower surfaces of respective links (30) of the crawler belt (29) to guide same in a direction tangential of the drive sprocket (25) when the crawler belt (29) is taken up onto the drive sprocket (25). The crawler belt support block suppresses vertical movements as would occur to the crawler belt (29) when taken up onto the drive sprocket (25) in a polygonally bent shape, to reduce the repeated striking noises generated by meshing engagement of bushes (32) of the crawler belt (29) and the drive sprocket (25).
摘要:
A track wheel having a self supporting track (1) mounted on a pair of load bearing rollers (2, 3). The track (1) comprises a continuous resilient band having a preformed transverse and longitudinal curvature for resisting flattening to a larger radius under load but substantially free to bend to a smaller radius of curvature for passage around the rollers. The radius (8) of transverse curvature is made approximately equal to the radius (7) of said rollers, and the radius (15) of longitudinal curvature is made not greater than 20 times the radius (8) of the transverse curvature to provide a short track wheel having a high load capacity and large surface contacting area or footprint.
摘要:
A track assembly comprising an endless track chain made up of identical track links and a cooperating sprocket wheel. The track link is formed with a ground engaging surface, a running surface and hinge members suitable to interact with hinge members on adjacent track links. The track link has a central drive cam and a guide. The cooperating sprocket wheel is formed of two laterally spaced running rims and a plurality of circumferentially spaced drive teeth engageable with the raised drive cam of the track link. The running rim has a side surface engageable with the guide.

A driving device comprises at least one chain (16) in the form of a closed loop. The chain is connected to at least one driving member arranged to cause the chain to orbit. Furthermore, the chain is laid over diverting members which in combination with the driving member determine the form of the loop. A rubber element (17) is arranged on the face of the chain located outermost in the loop and forms a configuration generally enclosing the chain loop. The rubber element (17) is in a driving force transmitting engagement with the chain (16) to be caused to orbit thereby. The rubber element (17) serves for engagement with for instance tree trunks over a large surface.
