Uncoupling pulley having a longitudinal axis, and including a wheel rim having a first zone, to receive a belt connecting the wheel rim to a first power transmission element, and second zone situated in the axial extension along the direction defined by the longitudinal axis of the pulley, of the first zone; a hub to be secured to a second power transmission element; one of the power transmission elements being driving, and the other being driven; a ring mounted below the second zone of the wheel rim and around the hub, so the ring can rotate, around the longitudinal axis, relative to the wheel rim and/or the hub; an elastically deformable element mounted between the hub and the ring; and a unidirectional clutch having an end fastened to the ring and the remaining part of which is mounted below the second zone of the wheel rim and above the ring.

A universal temporary wheel is provided that has a universal aperture pattern that is adapted to mate with different configurations of lug bolt patterns to enable the wheel to be used with various wheel hub configurations having various lug bolt patterns. The universal temporary wheel can be installed while a damaged wheel is being repaired to allow an automobile or other vehicle to be moved. Because the universal temporary wheel has a universal aperture pattern, the wheel can be used with a variety of wheel hub configurations and lug bolt patterns, thereby eliminating the need to stock a variety of temporary wheels having various aperture patterns.

An attachment for a vehicle wheel allows operation when the tire is flat. The attachment may include a main body which is circular or substantially annular when seen in an axial direction, a positioning device for positioning the attachment on a rim of the vehicle wheel, and a fastening device for fastening the attachment to the rim of the vehicle wheel. The fastening device may be adapted to be actuated independently of the positioning device.

A wheel guard includes a guard member disposed on a compactor wheel. The guard member has a first side having a first portion and a second portion. The second portion is offset from the first portion such that to define a first stepped recess therein. The guard member has a second side disposed opposite to the first side. The first portion has a first cross-sectional thickness and the second portion has a second cross-sectional thickness such that the second cross-sectional thickness is lesser than the first cross-sectional thickness. The guard member has a first top surface defined by the first portion, and a second top surface defined by the second portion and partially by the first portion. The second top surface is offset from the first top surface such that to define a second stepped recess therein. The wheel guard includes a base plate and a wear pad coupled thereto.

An attachment for a vehicle wheel allows the vehicle to be driven when the tire is flat. The attachment includes a main body having a mounting portion and a running surface portion. When ready to be mounted, the mounting portion has a closed circumference.

Various implementations include a wheelchair traction attachment device. The device includes a frame having an arcuately-shaped longitudinal axis, an inner surface, an outer surface opposite and spaced apart from the inner surface. The frame has a first edge extending between the inner and outer surfaces, and a second edge spaced apart from the first edge. At least a portion of the inner surface defines a channel. The device includes at least one first wheel-clip extending radially inwardly from the first edge of the frame relative to the arcuately-shaped longitudinal axis. The device includes at least one second wheel-clip extending radially inwardly from the second edge of the frame relative to the arcuately-shaped longitudinal axis. The device includes a traction portion disposed along at least a portion of the outer surface, the traction portion extending radially outwardly from the outer surface relative to the arcuately-shaped longitudinal axis.
