A rim for a vehicle wheel having an inner and an outer rim flange, an inner and an outer rim shoulder, a rim well with well base, inner well flank and an outer well flank, a transition section and an inner hump with a hump peak. The rim is having specific material thickness in the area of the transition section. In order to improve wheels in terms of weight minimization and noise development, the transition section comprises at least one stiffening section with a radially offset wall section, the maximum radial offset of which to the adjoining transition section is greater than the material thickness in the transition section. The stiffening section has a diameter, being equal or greater than the diameter on the well base and smaller than diameter of the hump peak.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

The invention relates to a device (3) for protecting a wheel rim (2) of a motor vehicle, wherein: an outer side of a rim flange (4) is covered by the device (3); the device (3) consists of a ring (5), the diameter of which is matched to that of the rim flange (4); and the ring (5) has a circumferential tongue (5.2) for fastening the device (3) to the rim flange (4), which tongue can be clamped between an inner side of the rim flange (4) and a side wall of a tyre (1). The device (3) is intended to be held securely on the wheel rim (1) even at very high speeds and correspondingly large forces acting on the device (3). No changes to the wheel rim (1) are necessary, and installation is simple. This is achieved in that the single ring (5) is produced from a hard material and has a continuous radial gap (6) and in that end faces (5.3) of the ring formed by the gap (6) can be connected by means of a clamping screw (8).

The invention relates to a caster for movable objects, and more particularly a bed caster, and at least comprises: a running wheel; a fork receiving said running wheel; a guide tube which is designed to be swivelable relative to the fork via at least one bearing; locking means provided on the fork side; and a braking system which can be brought into operative connection with the running wheel and is designed to block rotation of the wheels, characterised in that the braking system includes a brake shoe, a brake spindle, a guide pin and a cup-shaped guide element, wherein the brake spindle has groove-shaped guides, the cup-shaped guide element is provided with projections, and the projections can be brought into operative connection with the guides of the brake spindle in order to form the anti-rotation means.

A wheel assembly for a tire includes a circular hub member for securing to a rotatable axle of a vehicle, a first rim piece for engaging the hub member, a second rim piece for engaging the first rim piece, and a plurality of cylindrical sleeves for engaging both the first rim piece and the second rim piece. The first rim piece has cylindrical first shafts each engaging a first end of one of the sleeves. The second rim piece has cylindrical second shafts each engaging a second opposite end of one of the sleeves. An outer cylindrical surface of each sleeve engages a separate and distinct part the tire.

A non-pneumatic tire and wheel assembly which includes a rim, and a spoke ring structure having an inner ring that is mounted on an outer surface of the rim. The inner ring has one or more retention nubs aligned for reception in complementary shaped grooves on the outer surface of the rim, wherein the spoke ring structure has a plurality of spoke members, and an outer tread ring is mounted on the outer circumference of the spoke ring.

A supporting wheel for motor vehicles including a load-bearing structure that includes an outer rolling surface and two opposite side walls which extend on parallel planes and between which there is at least one through hole; a central reinforcement body intended to be coupled to a hub of a motor vehicle and associated with the load-bearing structure; wherein the load-bearing structure is at least partly made of plastic material.

A hub for bicycles comprising a hub axle, a hub shell, a rotor, and a toothed disk freewheel including a pair of interacting freewheel components namely, a hub-side freewheel component and a rotor-side freewheel component. The freewheel components each comprise axial engagement components biased in the engagement position through a biasing device. The hub-side freewheel component is axially displaceably received in a threaded ring and non-rotatably coupled with the hub shell in the driving direction. The rotor-side freewheel component is non-rotatably provided at the rotor for transmitting rotational movement from the rotor to the hub shell in the engagement position of the two freewheel components. The threaded ring comprises a thread with a thread groove that extends along a helical line in an axial direction around a circumference of the threaded ring, where the helical line shows less than five full revolutions around the circumference of the threaded ring. The thread is screw-connected with a thread of the hub shell.

Some embodiments of the present disclosure provide manufacturing methods for a wheel rim, a spoke and a steel wheel and a steel wheel formed by the methods. The methods includes that: a wheel rim/a spoke blank is heated in a heating furnace, and the heated wheel rim/the heated spoke blank is transferred onto a hot press. A temperature of the wheel rim/the spoke blank being required to be kept above a required temperature in a process of transferring the heated wheel rim/the heated spoke blank to the hot press. Then the wheel rim/the spoke blank is formed in the hot press. A formed wheel rim and a formed spoke are connected to product a steel wheel.

A hubcap for a heavy-duty duty vehicle that includes mounting structure that is formed with and cooperates with a side wall of the hubcap to provide a stiff, rigid structure that enables non-cantilevered connection to a wheel hub. The mounting structure can be a plurality of elongated bosses circumferentially spaced about the side wall that are formed with corresponding elongated bolt openings to enable the non-cantilevered attachment to the wheel hub. The elongated bosses cooperate with the hubcap side wall to provide a stiffened or rigid structure between the elongated bolt openings for increased and more uniform clamping force on a sealing gasket between the hubcap and the wheel hub. The hubcap profile provides clearance for removal of an outboard mounted disc brake rotor in heavy-duty vehicle wheel end assemblies that include such rotor configurations. The hubcap may support simple mounting of a hub odometer.
