A detachable airplane wheel prerotation/landing brake cooling device is disclosed that comprises: an outer circular cage rim, an inner circular cage rim confronting and spaced apart from the outer circular cage rim, and a plurality of spaced apart arcuate blades spanning across and connecting the outer circular cage rim to the inner circular cage rim at a slant. Each arcuate blade includes a first section connected to the outer circular cage rim and a second section connected to inner circular cage rim. The plurality of slanted arcuate blades are, when the detachable airplane wheel prerotation/landing brake cooling device is being impinged by an airstream during the landing of the airplane, configured to (i) rotate the wheel about the axle in a forward direction, and (ii) funnel air into the plurality of annular spaces adjacent to the plurality of heat shields to thereby remove heat away from the disc brake assembly.

A braking system is presented that comprises a brake sphere rotor that is mounted to the wheel hub of an axle. The braking system incorporates a caliper arm assembly that comprises at least one caliper arm. Each caliper arm further comprises hemispherical friction material located between the caliper arm and the brake sphere rotor.

A wheel hub is configured to rotate about an axis of rotation during operation, and includes a brake disk abutment surface against which a brake disk bears in an installed state, and a wheel-hub-side contact surface which is offset in an axial direction with respect to the brake disk abutment surface and which runs obliquely with respect to the axis of rotation and against which at least a part of a fastening assembly, by which the brake disk is fastenable or fastened to the wheel hub, bears in the installed state.

An in-wheel motor unit provided in a wheel of a wheel unit, includes: a motor having a rotor disposed on a radially outer side of a stator; a brake disposed on an inner side of the motor; and a housing that accommodates the motor and the brake. Further, the housing has a cylindrical partition that radially partitions a space for accommodating the motor and a space for accommodating the brake, the stator is fixed to an outer peripheral surface of the partition, and the brake is disposed on an inner peripheral side of the partition, and a fixing portion included in the brake is fixed to the housing.

An example wheel assembly includes a wheel hub including a first bore having a first central axis, and a wheel including a second bore having a second central axis. The first central axis is offset from the second central axis. The example wheel assembly includes a wheel stud extending through the first bore and the second bore to couple the wheel and the wheel hub. The wheel stud has a first portion proximate to the first bore and a second portion proximate to the second bore. The example wheel assembly includes a wheel nut threaded onto the wheel stud. The first portion of the wheel stud is to move from a first position relative to an axis of rotation of the wheel hub to a second position relative to the axis of rotation when the wheel nut is tightened to fix the wheel to the wheel hub.

Wheel assembly, in particular for a wheel chair comprising. The wheel assembly includes a wheel shaft extending along a shaft axis and which is configured to be non-rotatably connectable to a frame of the wheelchair. A wheel with a wheel hub is mounted on the wheel shaft so as to be rotatable around the shaft axis. The wheel assembly is provided with a hub motor having a power input and with a rim handle connected to the wheel and being rotatable relative to the wheel over an angle. A resolver assembly of the wheel assembly comprises a wheel resolver which is configured to generate a wheel resolver signal, a rim handle resolver which is configured to generate a rim handle resolver signal, and at least one resolver assembly output for outputting the wheel resolver signal and the rim handle resolver signal.

A wheel bearing assembly includes a bearing unit having first and second bearing rings mounted for relative rotation, the first bearing ring including a flange configured to connect the first bearing ring to a wheel rim, the flange including a plurality of threaded bores. A plurality of stud bolts each having a first portion, a second portion and an intermediate collar separating the first portion from the second portion are mounted in the bores such that the first portions are located in the bores and the first axial face of the intermediate collar abuts the flange. A second axial face and/or a radially outer portion of the intermediate collar includes at least one projection or groove configured to form an interference fit with another component.

A rod-end front suspension is provided for an off-road vehicle. The rod-end front suspension comprises a spindle assembly that is pivotally coupled with an upper suspension arm by way of a first rod-end joint and pivotally coupled with a lower suspension arm by way of a second rod-end joint. A steering rod-end joint coupled with the spindle assembly pivotally receives a steering rod. An axle assembly coupled with the spindle assembly conducts torque from a transaxle to a wheel coupled with the spindle assembly. Each of the first and second rod-end joints comprises a ball rotatably retained within a casing. The ball is fastened within a recess between parallel prongs extending from the spindle assembly. A threaded shank extending from the casing is threadably fixated with the suspension arm, such that the spindle assembly may be moved with respect to the casing and the suspension arm.

A brake rotor includes a friction portion, a hat portion axially extending from the friction portion and including a top face that is axially displaced from the friction portion and a side wall that extends from the friction portion to the top face, and a nose portion which extends axially from the top face of the hat portion away from the friction portion.

A wheel hub having an axis of symmetry and including a flange transverse to the axis of symmetry and provided with a plurality of fixing holes for attaching a wheel, a tubular body extending axially from the flange for supporting a rolling bearing, and a centering device arranged on a side of the flange opposite to that of the tubular body and in a position concentric with the axis of symmetry of the wheel hub, for retaining a wheel rim or a brake disc. The centering device being provided with a given number of flattened areas extending circumferentially and axially on a respective continuous tubular body projecting axially from the flange.
