Abstract: A protective cap is installed in a wheel hub to protect a wheel speed sensor and bearing assembly from intrusion of dirt. The hub has inner and outer end faces, and a central bore having splines for engagement by a splined driveshaft. The speed sensor system has a segmented disc rotating with the hub and a sensor mounted on a housing and extending into proximity with the segmented disc. The protective cap includes a stem for insertion through the central bore and a head having an under face for engaging with the inner end face of the hub. The head has a distal rim portion overlapping the housing to allow rotation of the protective cap relative the housing to prevent entry of dirt to the speed sensor system and bearing. The stem has yieldable retainers for engaging with the outer end face of the hub to retain the protective cap.

Abstract: A packaging system for protecting a wheel hub containing inboard and outboard bearings separated by a spacer. The packaging system comprises a shipping retainer having inboard and outboard elements that are reversibly locked together within the axial bore of the wheel hub to seal the ends of the axial bore and maintain the alignment of the bearings and spacer. The packaging system further includes a stackable shipping tray having first and second sides, the first side adapted to receive the inboard end of a wheel hub with the shipping retainer installed and the second side adapted to receive the outboard end of a wheel hub. The shipping tray cooperates with the shipping retainer to facilitate assembly and disassembly of the shipping retainer.

Abstract: A protection structure for outer shell of a hub comprises: a hub and an outer shell mounted at one end of the hub, the outer shell is provided at one end close to the hub with an enlarged flange, on an outer peripheral surface of the outer shell are annularly and spaced-apart formed a plurality of splines and at least one positioning rib, at least at one side of each splines is disposed a protection structure whose material is different from that of the outer shell. By such arrangements, the protection structure can be assembled with the cassette to prevent the cassette touching the splines, thus preventing the damage of the outer shell of the hub.

Abstract: The invention relates to a wheel hub having a central section and having a radial section which radially adjoins said central section, having a bearing section which projects axially from the central section for holding a wheel bearing and having an axially opposite holding section for holding a brake disk and a wheel rim, wherein holes for holding wheel bolts are formed in the radial section. In order to obtain a particularly light wheel hub which can withstand all operating loads and offers a reliable contact face for a brake disk under all operating conditions, it is provided that the wheel hub has recesses at least between some holes, which recesses extend completely through the wall of the radial section of the wheel hub, and that stiffening ribs are formed between the respective recesses which stiffening ribs axially thicken the radial section between the recesses.

Abstract: The invention relates to a wheel hub having a central section and a radial section which is radially connected to the central section, a bearing section which axially protrudes from the central section and is used to receive a wheel bearing, and an axially opposing receiving section for receiving a brake disk and a wheel rim. Holes for receiving wheel nuts are formed in the radial section. In order to produce an especially light wheel hub that can withstand all operating loads and provides a brake disk with a secure abutment surface under all operating conditions, the wheel hub has recesses at least between some holes, the recesses fully penetrating the wall of the radial section of the wheel hub, and at least one reinforcing means is embodied on the radial end of the wheel hub.

Abstract: A composite vehicle wheel hub includes an inner wheel hub portion formed from a first material and an outer wheel hub portion formed from a second material and joined to the inner wheel hub portion. A method for producing the composite vehicle wheel hub of this invention includes the steps of: (a) providing one of an inner wheel hub portion and an outer wheel hub portion formed from a first material; (b) placing the one of the inner wheel hub portion and the outer wheel hub portion in a mold; (c) casting the other one of the inner wheel hub portion and the outer wheel hub portion formed from a second material in situ within the mold to thereby produce the composite vehicle wheel hub; and (d) removing the composite vehicle wheel hub from the mold.

Abstract: The invention relates to a circuit device for realizing a non-linear reactive elements scale network, wherein the non-linear elements of the network are pairs of inductive and capacitive components cascade connected between a pair of input terminals and a pair of output terminals. Advantageously in the invention, each component of the network is formed by cascade connecting a first and a second transconductance integrator with each other.

Abstract: The present invention relates to a wheel hub having a cylindrical main body and a radial flange, with radial ribs extending between the outboard side of the radial flange and the outboard end of the main body.

Abstract: On a compactor wheel having outer and inner cylindrical drums, the inner drum being mounted on the vehicle axle, there is provided an axially extending shroud. The shroud is equipped with a cover plate which together serves to define a cavity enclosing the axle seals and bearings preventing trash from intruding into those components of the compactor vehicle.

Abstract: Wheel structure for a trash container comprising an enhanced thickness hub portion defined by positioning a metal member within the locus of the wheel wall during molding so as to increase wall thickness by better heat transfer and increase resin buildup in the vicinity of the metal member. The metal member is usefully a fastener for the end of the wheel carrying axle whereby the position of the wheel on the axle is fixed by the fastening metal member being trapped in the increased wall thickness hub.

Abstract: The invention relates to a ground engaging member for use in hand or gravity powered vehicles such as hand-trucks, trolleys, push-chairs, bicycles, roller-skates, bobcats, grass-skis and amphibious craft and the like, made of a moulded plastics ball. Incorporated in the ball-like member are two diametrically opposite sockets each accommodating a bearing. Each bearing is arranged to accomodate a vehicle axle assembly. The bearing housing and the socket are correspondingly tapered inwardly so that the bearing housing may be pushed into the socket until it is gripped fully by the walls of the socket, and the socket depth is arranged to be greater than the length of the bearing housing.
