Abstract: The Dual Tire Shield of the invention mounts between dual tires and helps to prevent debris from getting into the gap between dual tires and/or damaging the tires when it does so. In some embodiments it can also serve as a runflat for dual tires. Debris can become wedged between the sidewalls of dual tires that face each other, or “inner sidewalls” of such tires. The dual tire shield prevents debris from getting stuck between the inner sidewalls of the dual tires and thereby prevents flats caused by sidewall puncture or bead de-seating due to such debris. The device accomplishes this by: Blocking debris from entering the gap between duals and/or prevent debris from being wedged in the gap; keeping such debris from contact with one or both of the tires even if wedged therebetween; and/or ejecting debris from between the tires. Further, the dual tire shield may be made rigid enough and/or include rigid portions so as to act as a runflat in case a tire goes flat regardless of the reason.

Abstract: A scraper assembly includes a first scraping member configured to be positioned below a horizontal centerline of a rotating assembly and rearward of a vertical centerline of the rotating assembly. The first scraping member is configured to remove debris from the rotating assembly at least while the rotating assembly is rotating in a first direction. The scraper assembly also includes a second scraping member configured to be positioned above the horizontal centerline of the rotating assembly and forward of the vertical centerline of the rotating assembly. The second scraping member is configured to remove debris from the rotating assembly at least while the rotating assembly is rotating in a second direction, opposite the first direction. In addition, the scraper assembly includes a support structure configured to couple to a frame of an off-road vehicle, and the first and second scraping members are coupled to the support structure.
Abstract: A robot cleaner includes wheels mounted at a lower side of a main body of the robot cleaner to allow for traveling of the main body, and wire winding prevention members mounted at the lower side of the main body, each wire winding prevention member having one end extending to be contactable with a rim of the corresponding wheel. The wire winding prevention member is preferably a torsion spring.

Abstract: Rear wheel tires of a vehicle body are spaced apart from each other in the vehicle width direction. A foreign object removing device is provided between an outer tire and an inner tire of the rear wheels on one side of the vehicle for removing foreign objects between the tires. The foreign object removing device includes a bar-shaped member inserted in a suspended state between the tires, and a shoe provided in a lower end side of the bar-shaped member to collide with foreign objects such as earth and sand, and stones getting in between the tires for flicking out the foreign objects from between the tires. The shoe is replaceably attached to the lower end side of the bar-shaped member by using a bolt. In a case where the shoe wears down, only the shoe is replaced.

Abstract: An all-terrain straddle type vehicle includes, inside a wheel, a disc rotor that rotates as the wheel rotates, a caliper for clamping the disc rotor to brake the rotation of the wheel, and a scraper for scraping out dirt, mud, sand, snow and other debris deposited on a rim of the wheel. An edge of a scraping surface of the scraper extends obliquely from upstream toward downstream of a rotation direction of the wheel with respect to a rotation plane of the wheel.
Abstract: A scraper structure for a vehicle includes a scraper for scraping material accumulated inside a disk wheel of a wheel. The scraper is detachably attached to a lower surface of a knuckle which rotatably supports the wheel. The scraper includes an extending portion and a bent portion. The extending portion extends inwardly in terms of a vehicle body and downwardly from the lower surface of the knuckle. The bent portion is formed by bending a lower end of the extending portion toward a front in terms of the vehicle body.
Abstract: A foreign matter removing device which is capable of reliably removing foreign matter from between a double tire includes at least one foreign matter removing member interposed in a space of at least one double tire. A dimension in a width direction of the foreign matter removing member in a vicinity of a tip end portion thereof is larger than a dimension in a diameter direction from an outer peripheral portion of a hub, on which the double tire is fitted, to an outer peripheral portion of a rim of at least the one double tire.
Abstract: A mud flap extender for mounting on the rear quarter panel behind each rear wheel or wheels of a truck or other vehicle and suspending a mud flap a sufficient distance rearwardly of the wheel(s) to prevent the wheel(s) from engaging the mud flap and tearing the mud flap from the vehicle frame when the vehicle is operated in reverse. Each mud flap extender is characterized by a fender module that matches the curvature of the vehicle rear quarter panel and typically mounts on the wheel well plate of the rear quarter panel and an angle-iron mount plate having a top flange for engaging the fender module and a bottom flange for mounting a mud flap which is suspended downwardly from the fender module in spaced relationship with respect to the rear wheel or wheels of the vehicle.
Abstract: During the operation of a track-type machine in abrasive terrain, it is common to have foreign material deposited between the engagement surfaces of a track chain assembly. The presence of this foreign material between these surfaces has been known to greatly accelerate the wear between these components. The present invention provides a pair of deflecting plates that are positioned adjacent and in overlying relation to certain engagement surfaces of various components of the track chain assembly 14. The deflecting plates direct foreign material away from contact with the engagement surfaces and thereby reduce the wear of the track chain components.
Abstract: A tire scraper for removing mud from a vehicle having dual tires, includes a plurality of scraper bars, each carrying a plurality of brush assemblies. An actuator moves the pivotal support member between a first retracted position and a second deployed position.
