Patent number: 8936324Abstract: A cross-link for a track that comprises belts spaced apart to accommodate a plurality of wheels of a tracked vehicle on which the track is mounted, the belts having a ground-facing side. In one embodiment, the cross-link comprises an elongate member for mounting to the belts to interconnect the belts, the elongate member having a belt-engaging face contacting the belts on the ground-facing side when the elongate member is mounted to the belts. The elongate member defines a channel including a bottom portion and a pair of sidewalls opposite one another on either side of the bottom portion. The cross-link also comprises a sole mountable in the channel for engaging a ground surface on which the tracked vehicle travels, the sole comprising a pair of sidewall-engaging surfaces for engaging the sidewalls when the sole is mounted in the channel.Type: GrantFiled: October 15, 2008Date of Patent: January 20, 2015Assignee: Snowgrolic S.A R.L.Inventors: Francois Paquet, Amine Khimjee, Patrick Bernard

Patent number: 6637840Abstract: A track support element includes an elongate body. A first tire containment member is positioned along the elongate body. A second tire containment member is positioned along the elongate body in spaced relation to the first tire containment member. Either the first tire containment member, the second tire containment member or both are movable along the elongate body whereby the relative distance between the first tire containment member and the second tire containment member is adjustable to accommodate vehicular tires having differing widths.Type: GrantFiled: November 9, 2001Date of Patent: October 28, 2003Inventors: Tom Zaleski, Mark Leslie Middleton

Patent number: 6354677Abstract: A bearing for use with a snowmobile track is disclosed. The bearing includes an axle surrounded by a sleeve which is free to rotate when the snowmobile track is driven by the machine. The rails of the suspension systems of the snowmobile ride on the rolling surface resulting in reduced friction. The bearing can be used in a clip on the track or can be included in the track itself. A lubricious coating is utilized to reduce friction between the axle and the sleeve or bushing rotating about the axle.Type: GrantFiled: March 10, 1998Date of Patent: March 12, 2002Assignee: Industrial Fluid Technologies, Inc.Inventors: James S. Cook, Chad M. Olson

Patent number: 6186604Abstract: Two endless wire rope loops spaced lengthwise of elongated grouser-mounting base plates of a tractor endless tread are secured to the grouser-mounting base plates by spaced U-shaped bows of clamping strips bolted to the grouser-mounting base plates, and the adjacent edges of adjacent clamping strips have interfitting projections and sockets for transmitting shear forces between such adjacent clamping strips.Type: GrantFiled: October 13, 1998Date of Patent: February 13, 2001Inventor: Tyman H. Fikse

Patent number: 6125956Abstract: An all-terrain vehicle comprising in combination:a central frame having two parallel sides each one comprising:a toothed wheel (50) mounted on one side of the central frame at the front, two pivoting suspension tandems mounted on a support fixed on the side of the frame, a track surrounding, without prior tension, the wheels and tandems, a return wheel (92) aligned with the tandems and keeping the track around them. The track comprises a pair of elastomer bands (38, 40) disposed at a certain distance from each other; stoppers (33) are also disposed around the bands, and comprise a traction bar (34) transversally binding a band to another; two triangular guides (36) are installed inside a band and spaced outwardly to demarcate a tread (42) to receive successively wheels and tandems. A fixing bolt (74) holds the guide and the traction bar across the band. A second toothed wheel is mounted on the opposite side of the central frame and power driven independently.Type: GrantFiled: September 29, 1997Date of Patent: October 3, 2000Inventor: Guy Gignac

Patent number: 6109705Abstract: A snowmobile drive track for travelling on various surfaces including icy surfaces, hardened snow surfaces and semi-hardened surfaces comprises an endless body having, on its ground engaging outer side, projecting profiles having peaks of different height. The first highest peaks bear on icy surfaces, while, on hardened snow surfaces, the second highest peaks also engage the ground; on semi-hardened snow surfaces, all peaks engage the ground.Type: GrantFiled: August 7, 1998Date of Patent: August 29, 2000Assignee: Camoplast, Inc.Inventor: Denis Courtemanche

Patent number: 6030057Abstract: Endless loops spaced lengthwise of elongated grouser-mounting plates of a tractor endless tread in which each loop includes two side-by-side stretches of wire rope having the interstices between the strands of both wire rope stretches filled with elastomer material, and both stretches of wire rope being embedded in elastomer material integrating the two stretches into a single embedment, the two wire rope loops being secured to the grouser-mounting plates by spaced U-shaped bends of clamping strips bolted to the grouser-mounting plates, and spacer plates bridge between adjacent grouser-mounting plates and make loose tongue-and-groove joints therewith for enabling the grouser-mounting plates and the spacer plates to tilt relatively as the endless tread travels around a tractor wheel, but the straight tread portion of the tread extending between tractor wheels spaced lengthwise of the tractor is substantially inflexible inward.Type: GrantFiled: February 3, 1998Date of Patent: February 29, 2000Inventor: Tyman H. Fikse

Patent number: 5951125Abstract: A roller belt arrangement for a CATERPILLAR (endless track) vehicle has at least one pull resistant belt having a first surface and a second surface opposite the first surface. Drive members are connected to the first surface of the at least one pull resistant belt and extend transversely to a longitudinal extension of the at least one pull-resistant belt. The drive members have a U-shaped foot comprising a stay and two legs, wherein the stay rests on the first surface and the legs project perpendicularly from the first surface. The bolts, having a head and a threaded end opposite the head, are provided for connecting the drive members to the at least one pull-resistant belt. Plate members are non-rotatably positioned between the legs. The bolts penetrate the at least one belt, the stays, and the plate members, with the threaded ends positioned between the legs. Nuts, threaded onto the threaded ends of the bolts, are provided for securing the bolts and are nonrotatably secured relative to the plate members.Type: GrantFiled: May 9, 1997Date of Patent: September 14, 1999Assignee: Arnold JagerInventors: Arnold Jager, Claudius Jager, Sebastian Jager

Patent number: 5902021Abstract: A roller belt arrangement for a track-type vehicle has pull-resistant belts with a first surface and a second surface opposite the first surface. Drive members are connected to the first surface of the pull-resistant belt so as to extend transverse to a longitudinal extension of the at least one pull-resistant belt. U-shaped members, having a stay and two legs defining a cavity therebetween, are positioned on a second surface opposite the drive members such that the stay rests on the second surface. Cushion members are positioned in the cavity of the U-shaped members. Screw bolts for connecting the drive members to the pull-resistant belt are provided. The screw bolts extend sequentially through the cushion member, the stay of the U-shaped member, the pull-resistant belt, and the drive member. The screw bolts are directly threaded into the drive members.Type: GrantFiled: February 21, 1997Date of Patent: May 11, 1999Inventor: Arnold Jager
