摘要:
A preassembled hub assembly is presented having components including the inboard and outboard bearings (30, 40), spacer (24), and lubricant seal (14) preassembled inside the hub at the manufacturing facility. In addition, the manufacturing facility also affixes a pre-positioned spindle nut assembly (50) to the hub assembly, the assembly being held in place by a retaining ring (16). The preassembled hub assembly (with the pre-positioned spindle nut assembly affixed to the hub) has no separate or loose parts, facilitating shipment and installation of the hub assembly. Installation only requires placement of the novel hub assembly on the spindle and the tightening of the factory installed, pre-positioned retaining nut (70).
摘要:
A spindle nut assembly (50) is presented comprising the following three components: a washer (60), a locking snap ring (80), and a nut (70). Each of these three components function together, and in conjunction with the spindle of a vehicle axle, to affix a wheel hub assembly onto the spindle of an axle. The three components comprising the spindle nut assembly incorporate design features allowing the components to interlock and resist loss of preload compression on the hub assembly.

The invention relates to an omni-directional wheel, having a hub (7) that can be rotated about a rotational axis (RT), two wheel disks (8a, 8b) connected to the hub (7) and disposed coaxially to the hub (7), a number of spherical roller bodies (6) disposed between the wheel disks (8a, 8b), evenly spaced along a circumferential casing of the wheel (5a-5d), aligned at the roller axes (RA) thereof at a diagonal angle to the rotational axis (RT) of the hub (7), and supported in a freely rotating manner with regard to the wheel disks (8a, 8b) at the opposite ends thereof. In order to create an omni-directional wheel while maintaining opposite wheel disks, said wheel being robust relative to the operating requirements, the invention proposes supporting the roller bodies (6) on receiving components (9) in a freely rotating manner, and mounting the receiving components (9) on the wheel disks (8a, 8b).

An axle assembly in portal arrangement, especially for a driven axle of low floor vehicles has an axle housing with a main drive, portal drives fixed to both sides of the axle housing, wheel end drive assemblies fixed to portal drive houses and carrying vehicle wheel rims, and wheel braking means connected to the wheel end drive assemblies. The improvement achieved by this invention is that an outlet of each portal drive (104) is connected to the vehicle wheel rims, respectively, by a hollow spindle (112) being rotatably arranged in a gear housing (109) of each wheel end drive assembly (108) by roller bearings (110, 111) with conical rollers in a pre-stressed manner.

The present invention provides a method of constructing a wheel of the type comprising a first portion (12) connected to a second portion (11), the second portion providing a rim, comprising the steps of providing an outer surface of the first portion with at least one recess (15), positioning the second portion (11) such that it surrounds the outer surface of the first portion and deforming a surface of the second portion such that the resulting deformation(s) protrude into the or each recess provided on the outer surface of the first portion such that the first portion is connected to the second portion (11).
摘要:
A hub (2) includes a spindle (14) which projects through a housing (4) and rotates relative to the housing (4) on a bearing (6) that is located between the spindle (14) and the housing (4). The bearing (6) has two sets of raceways (28,40) that are oblique to the axis x, and in addition rolling elements (36) arranged in two rows between the sets of raceways (28,40). The inner raceways (28) that fit around the spindle (14) and have back faces (32), with the back face (32) for one of the races (26) being against a shoulder (18) from which the spindle (14) projects. Initially, the end of the spindle (14) projects straight beyond the back face (32) of the outer race - indeed, so that the races (26) can be installed over the spindle (14). But once the housing (4) and races (26) are in a position around the spindle (14), the projecting end portion of the spindle (14) is deformed radially and axially in a rotary forming operation such that it transforms into a formed end (20) that lies behind back face (32) of the race (26). With the two races (26) between the formed end (20) and the shoulder (18). During the rotary forming operation the hub (26) rotates, and the end of its spindle (14) is forced against a rotating forming tool and the force is monitored. The housing (4) is restrained and the torque transferred from the rotating hub (2) to the housing (4) is monitored.
