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 wheel bearing apparatus, incorporating a wheel speed detecting apparatus, has a mounting portion (17) on a cover body (15). It includes an insertion portion (17a) formed with a bottom insertion bore (22), and a cylindrical securing portion (17b). A wheel speed sensor unit (18) is secured in the insertion portion (17a) by a securing bolt (21), via a mounting member (20). The insertion portion (17a) of the mounting portion (17) is arranged at a horizontal position through the center of a bottom 15c of the cover body (15). The securing portion (17b) is arranged at a position vertically below the insertion portion (17a). The wheel speed sensor (18) and a pulser ring (14) oppose each other, via a bottom (22a) of the insertion bore (22). A discharging portion, with an axially extending slit (24) or discharging groove (26), is formed at a road surface-side of the insertion bore (22) to communicate the insertion bore (22) with the outside.

A bicycle having a rear wheel including an axle, a hub shell, a torque element including a torque output portion and a torque input portion, and a rear cog coupled to the torque input portion. The torque output portion is a first radial distance from the torque input portion. The position sensor measures a rotational position of the torque input portion relative to the torque output portion. In one embodiment, the position sensor includes a displacement indicator (e.g., a radial tab mounted to the torque output portion) and a displacement sensor (e.g., an inductive sensor mounted to the torque input portion). The inductive sensor preferably has two sensing coils positioned on each side of the displacement indicator. The hub assembly can further comprise a wireless transmitter adapted to transmit data from the position sensor. The hub shell preferably includes a window that facilitates data transmission from the wireless transmitter.

A roller bearing module for a vehicle hub module having an outboard roller bearing and an inboard roller bearing. The roller bearing module provides a spacer coupling the outboard roller bearing to the inboard roller bearing. The spacer is arranged in an axial direction between the outboard roller bearing and the inboard roller bearing. The roller bearing module includes a first sealing structure arranged at an outwards facing side of the outboard roller bearing. The roller bearing module further includes a second sealing structure arranged at an inwards facing side of the inboard roller bearing.

A rolling-element bearing unit for a wheel bearing assembly of a vehicle includes a first rolling-element bearing having an outer bearing ring and an inner bearing ring and rolling elements disposed between the outer bearing ring and the inner bearing ring and a first seal element having a seal-element base body having a first support member mounted to an axial outer surface of the inner bearing ring and a first seal lip pressed against a radial end surface of the outer bearing ring to hold the outer bearing ring in position relative to the inner bearing ring. Also a wheel bearing assembly including two such rolling element bearing units.

A motor vehicle wheel bearing assembly includes a hub configured to be supported by at least one rolling-element bearing and to provide a seat for a wheel. The hub includes a first hollow-cone-shaped element manufactured from light metal and having a first axial end section having a first diameter and a second axial end section having a second, larger, diameter and at least one bearing raceway or raceway support at the first axial end section. The hub also includes a second element extending radially from an end of the first hollow-cone-shaped element, the second element having a radially inner section and a radially outer section. The second axial end section of the first element is connected to the radial outer section of the second element, for example, at a joint.

A method of adjusting preload on a bearing assembly of a wheel mounted on an axle or spindle with a lock nut includes mounting a preload adjustment tool onto a threaded axle or spindle. The load on the bearing assembly is increased using the tool. The wheel on the axle or spindle is rotated to set the bearing assembly. The load on the bearing assembly is decreased to a desired maximum preload on the bearing. After decreasing the load on the bearing assembly to a desired maximum preload, the lock nut is tightened by hand until the lock nut cannot be further tightened. The lock nut is loosened by rotating the lock nut to a preferred location where a guide mark on the tool aligns with one mark on the lock nut located closest to the guide mark wherein a resultant preload on the bearing assembly is within a preset range from the desired maximum preload.

Wheel hubs for a motor-vehicle wheel hub assemblies provided with a bearing unit in turn which include at least one row of rolling bodies, the wheel hub being provided with at least two sheet-metal elements which are rigidly joined together, wherein a first sheet-metal element forms a raceway for the at least one row of rolling bodies.

A multiple directional wheel including a wheel frame comprising identical component parts. Each of the wheel frame components comprise: a hub having a main axis about which the multiple directional wheel is adapted to rotate; a hub rim radially surrounding the hub; a first plurality (four shown) of peripheral roller supporting arms (“first arms”) radially extending from the hub rim and aligned in a first plane; and a second plurality of peripheral roller supporting arms (“second arms”), each member arm of the second plurality of peripheral roller supporting arms having a radially inner base and being circumferentially offset with respect to diagonally adjacent members of the first plurality of peripheral roller supporting arms. Each of the wheel frame components further comprise a plurality of beams corresponding to the number of member arms of the second plurality of peripheral roller supporting arms, each respective beam extending from the hub rim to a corresponding inner base of a member arm of the second plurality of peripheral roller supporting arms, and a plurality of spigots extending from each corresponding one of the plurality of beams or the inner bases. The second plurality of peripheral roller supporting arms lie in a second plane normal to the main axis, spaced from, and parallel to, the first plane; and each of the spigots from one of the wheel frame components is received in a recess formed in a facing surface of a complementary one of the wheel frame components to join the wheel frame components to form the wheel frame.
