Abstract: The present invention provides a structure of fast-screwed two-piece type wheel rim, mainly comprises an inner half wheel rim and an outer half wheel rim both being installed with protruding skeletons at the outer ends and formed with a through hole in the center, the inner end of the inner half wheel rim is installed with a cylindrical protruding member having outer thread, an expansion protruding ring having an annular concave slot is installed at a base portion of the cylindrical protruding member for being installed with a seal unit, the inner end of the outer half thread. As such, the inner and outer half wheel rims can be respectively installed from two side of a tire for being directly integrally airtight combined by a positioning screw screwed through the positioning hole and installed the seal unit installed between the inner and outer half wheel rims.

Abstract: A wheel assembly for a vehicle includes a wheel having a first rim half and a second rim half secured together to form an annular outer rim for receiving a tire. The rim halves have aligned central openings and aligned apertures for receiving fasteners for mounting a wheel hub on the wheel. In one embodiment, at least the central opening of one of the rim halves includes a plurality of spaced recesses around its periphery. A rock guard built into the wheel includes a plurality of rock guard formations each forming a shield which fills at least a major portion of any space between a respective recess and the wheel hub to block at least some debris from passing through the wheel while allowing airflow through the wheel.

Abstract: A solid rubber tire with a flexible drive hub having a multiplicity of hub ribs and grooves formed around the periphery of the flexible drive hub and a solid rubber tire tread replaceably mounted on the flexible drive hub having a multiplicity of interior tread grooves and ribs formed around an interior surface of the tire tread, the tread grooves and ribs sized and shaped for interlocking engagement with the multiplicity of ribs and grooves formed around the periphery of the flexible drive hub.

Abstract: A wheel includes: a first wheel half having a disk portion formed with a central hole that is defined by a hole-defining wall, and a rim extending from a periphery of the disk portion; and a second wheel half having a disk portion connected to the disk portion of the first wheel half, and a rim extending from a periphery of the disk portion of the second wheel half away from the first wheel half. The rims of the first and second wheel halves extend in opposite directions and are adapted for mounting of a tire thereon. The disk portion of the second wheel half is formed with a middle hole and a central bushing that is bent from a periphery of the middle hole and that protrudes axially into the central hole in the disk portion of the first wheel half so as to contact intimately the hole-defining wall of the central hole.

Abstract: A wheel assembly for a vehicle such as a tractor is disclosed. The assembly comprises a wheel rim (10) for supporting a tyre, a nave plate (11) mounted to the rim, and a drive plate (21) mounted to an axle flange (26). A torque ring (18) has first key ways (16, 17) for cooperating with first keys (14, 15) on nave plate (11), and second key ways (19, 20) for cooperating with second keys (22, 23) on drive plate (21). In this way, torque and radial and axial forces are transferred between the drive plate (21) and nave plate (11), but radial or axial forces, tending to remove the assembly from the axle, and exceeding respective predetermined levels, are prevented from being transferred from the nave plate (11) to the axle.

Abstract: A composite wheel and a method of manufacture is provided for a vehicle wherein the composite wheel has a first and second section mounted to an annular mount. At least one of the first wheel section and second wheel section is composed of a resin having at least one braided polymeric fiber. The first and second sections are each formed by folding the braided fiber into a preform and then injecting resin into a mold containing the preform. The first and second sections are then bonded to each other and the annular mount.
