Wheel comprising a rim and a wheel center wherein the wheel center comprises several spokes extending in a longitudinal direction from a wheel hub to the rim. At least one spoke comprises an outer wall surrounding a cavity extending in the longitudinal direction of the at least one spoke. The cavity is delimited from the outer wall by an inner surface. The at least one spoke further comprises a reinforcing member extending along the inner surface.

This disclosure concerns wheels for industrial vehicles, including scissor lift vehicles and aerial platform vehicles. More particularly, this disclosure concerns a wheel fabricated with a substantially cylindrical wheel rim and a front face surface which includes a center hub section that is inwardly offset from the front edge by an amount and at an angle providing flexibility to recover from incidences that can damage the wheel.

A wheel with high strength flexible spokes of the present invention, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength. The wheel includes a nipple within the rim that receives the high strength spoke and allows for flexibility in adapting the spoke to wheels having differing shapes and sizes.

An automobile hub with a hollow rim includes a wheel disc and the rim with at least one hollow cavity, in which the rim includes at least two mutually nested rings and an axial end cap at the same ends of the at least two rings, and the hollow cavity consists of the rings and the axial end cap. The outer side of one end of the wheel disc includes axial rim mounting grooves, and the rim is inserted into the rim mounting grooves and fixed to the wheel disc through the end without the axial end cap. By employing the automobile hub with the hollow rim, the hub assembling method, and the automobile having the hub, the weight of the hub can be further reduced, and the hub has sufficient strength.

A first labyrinth seal includes: a drive shaft side annular protrusion that is formed on one of the slinger and the drive shaft seal plate and that protrudes over the circumference of the drive shaft; and a drive shaft side annular groove that is formed on the other of the slinger and the drive shaft seal plate and that recedes over the circumference of the shaft. A second labyrinth seal includes: a carrier-side annular protrusion that is formed on one of the carrier seal plate and the planetary carrier and that protrudes over the circumference of the shaft of the planetary carrier; and a carrier-side annular groove that is formed on the other of the carrier seal plate and the planetary carrier and that recedes over the circumference of the shaft.

A wheel bearing device has a vehicle-body-mounting flange 5b with a plurality of ears 10 discontinuously formed in a circumferential direction on an outer circumferential surface of the outer member 5. An outer circumferential surface 11 on the outer side of the outer member is tapered and formed such that a diameter of the outer member gradually decreases in a direction to an outer side. Ridges 16 protrude from a fitting surface 12 toward the outside in a radial direction. The ridges 16 are formed between the plurality of ears 10. The ridges 16 are forged to smoothly connect to the outer circumferential surfaces of the plurality of ears 10. Ribs 15 are forged on inner-side outer circumferential surfaces of the plurality of ears 10.

A vehicle axle includes, an axle gear unit housing and axle tubes adjoining the latter. The axle gear unit housing has an opening which is surrounded by a flange. Threaded blind bore holes extend beyond the thickness of the flange into the region of the wall of the axle gear unit housing which has radially outwardly on the side of the flange facing the axle gear unit housing a wall thickening which extends annularly radially circumferentially along the flange and which is configured in a continuously annular manner or so as to form spot faces partially in the areas of the threaded blind bore holes, wherein a joint flash extends in a central plane along the axle tubes and toward the flange 4 in the region of the axle gear unit housing and at the flange along the radially outer contour of the wall thickening.

A spigot joint part of a wheel hub has a cylindrical outer peripheral surface. The wheel mounting structure includes a collared member having a collar part to be press-fitted into and fixed to the spigot joint part, which is formed at a position away from an end part of the spigot joint part by a predetermined distance to protrude outward in a radial direction of the collared member. An annular protruding part is formed on a part of an inner peripheral surface of a center hole of a wheel to protrude toward a center of the wheel. In a state where the wheel is fixed to the flange part by using hub bolts, a fitting part and the annular protruding part are spigot-fitted. In a state where the hub bolts are removed, the annular protruding part is locked by the collar part.

An automobile hub of a multilayer rim includes a wheel disc and a rim that is composed of at least two layers of metal rings by nesting, and a gap is preset between two adjacent metal rings; an outer side of one end of the wheel disc includes axial rim mounting grooves, and one end of the rim is inserted into the rim mounting grooves to fix the rim to the wheel disc.

A method of making a work piece without the use of an auxiliary anode and a work piece created using the method are provided. The work piece includes a main face being generally planar. The work piece also includes a first area comprising a plateable resin configured to be plated using the plating process without the auxiliary anode and having a first current density during the plating process. Additionally, the work piece includes a second area comprising a non-plateable resin configured to not be plated using the plating process without the auxiliary anode. The first area and the second area are determined by a process referencing a predetermined minimum current density value with the first current density being greater than the predetermined minimum current density value.
