A heat shield for a wheel is disclosed. A torque bar may be used to mount the heat shield to the wheel, and includes a connector in the form of a stem and a head. A stiffening or reinforcement plate is mounted to the heat shield with a torque bar mounting aperture extending through the reinforcement plate being disposed about at least part of a torque bar mounting aperture extending through the heat shield. The torque bar mounting aperture of the reinforcement plate is disposed/configured such that the head of the torque bar may be disposed in overlying relation to portions of an outer surface of the heat shield that are on opposite sides of the torque bar mounting aperture through the heat shield that are exposed by the torque bar mounting aperture through the reinforcement plate.

A brake assembly for an electric motor includes: a magnetic body, a winding, a bolt, a housing part with a brake surface, an armature disk, a brake pad plate, a shaft, a spring part, and a first bushing. The housing part is connected to the magnetic body by the bolt, with a positive fit in at least the circumferential direction. The first bushing is accommodated in a second bushing. The spring part supported on the housing part presses the first bushing and/or the second bushing toward the magnetic body. The radial clearance range covered by the armature disk includes the radial clearance range covered by the second bushing, and the axial region covered by the armature disk includes the axial region covered by the second bushing.

The present invention relates to a wheel hub for vehicle axle used in trucks, buses, trailers and semi-trailers, consists of a cylindrical central body, said central body surrounded by a plurality of radial projections extending vertically from the median region of said central body, being structured by ribs integrated with said projections providing robustness, reduced weight and reduced heat transfer from the brake to tires.

The invention relates to a wheel for a powered two-wheeler, in particular a motorcycle or a motor scooter, that is at least sectionally made of a fiber-reinforced plastic material. A hub area (12) of the wheel (IO) is provided with two rigid, self-supporting, metal inserts (18, 20), which are arranged on axially opposite sides of the hub area (12), and which in an axial and radial direction (A, r) are connected to one another in a form-fit manner.

A vehicle airflow control device includes: a wheel shutter that is provided to a vehicle wheel, and is movable by a driving mechanism between an open position at which an opening between spokes of the vehicle wheel is brought into an open state and a closed position at which the opening is brought into a closed state; a shutter device that is provided to an introduction path of an air into an engine compartment, and is switchable between an open state in which an air is permitted to be introduced and a closed state in which an introduction of an air is blocked; and a control mechanism that actuates the driving mechanism to move the wheel shutter to either one of the open position and the closed position in accordance with the open and closed states of the shutter device.

A lightweight wheel spoke for an automobile increases the strength around the heat dissipation holes by thickening the material around the heat dissipation hole on the inner wall of the spoke. The thinning of the material between the heat dissipation holes, that is where there is no heat dissipation holes on the tapered barrel, enables the tapered barrel of the spoke to form a unique concave-convex structure on the inner wall or the outer wall, thereby enabling the entire spoke to be secured.

A heat shield for an aircraft wheel assembly is made of a heat shield material evenly distributed across the heat shield along both the circumferential and the axial directions. The heat shield material has a high thermal conductivity greater than 30 W/mK. In various embodiments, the thermal conductivity is greater than 85 W/mK. In this manner, thermal flux is maximized throughout the heat shield to distribute heat evenly across the heat shield in both circumferential and axial directions.

The invention relates to a vehicle wheel comprising a wheel rim (12) that has a hub portion (38), a rim base (36) for receiving a tire, a plurality of support portions (40) interposed between the hub portion (38) and the rim base (36), at least one interspace (42) between the support portions (40), and at least one cover element (44) associated with the interspace (42), characterized in that the cover element (44) can be transferred from a first position to a second position by pneumatic actuation.

A retainer assembly may comprise: a retainer main body having a first mounting flange, a second mounting flange, a body portion, a first rib and a second rib, the body portion extending from the first mounting flange to the second mounting flange, the first rib extending from the second mounting flange towards the first mounting flange, the second rib extending from the second mounting flange towards the first mounting flange, the first rib and the second rib extending orthogonal to the body portion; and a retainer sleeve having a first slot extending from the first axial end towards the second axial end and a second slot extending from the first axial end towards the second axial end, a portion of the first rib disposed in the first slot, and a portion of the second rib disposed in the second slot.

A vehicle wheel having a rim part to which a tire is mounted and a vehicle body attachment part which is attached to a vehicle body, in which the rim part has, on an inner circumferential surface thereof, a plurality of fins each having a heat dissipation surface, and in which the fins are arranged periodically along a circumferential direction.
