A wheel assembly for coupling to an axle may include an outer rim, and distal inboard and outboard attachment points coupled to the outer rim. An inboard axle attachment assembly may include an inboard medial portion to be coupled to the axle and angularly spaced inboard arms extending outwardly from the inboard medial portion and defining proximal inboard attachment points. An outboard axle attachment assembly may be rotationally offset from the inboard axle attachment assembly and include an outboard medial portion to be coupled to the axle and angularly spaced outboard arms extending outwardly from the outboard medial portion and defining proximal outboard attachment points. Inboard gas springs may each be coupled between respective ones of the distal inboard attachment points and the proximal inboard attachment points, and outboard gas springs may each be coupled between respective ones of the distal outboard attachment points and the proximal outboard attachment points.

The invention relates to a wheel rim for a vehicle wheel with cover elements.

A bicycle rim basically includes a first annular side surface portion, a second annular side surface portion, an annular connecting portion and an outermost layer. The first annular side surface portion includes a first braking surface. The second annular side surface portion includes a second braking surface. The epoxy resin layer is an example of a nonmetallic layer. The annular connecting portion connects the first and second annular side surface portions. The soft additive granules are disposed in at least one of the first and second annular side surface portions. The epoxy resin layer is disposed in at least one of the first and second annular side surface portions. The soft additive granules are at least partially embedded in the epoxy resin layer. The outermost layer covers the epoxy resin layer and the soft additive granules.

The present disclosure may relate to centerless wheel assembly that includes a centerless rim including a first center point laying in a first plane generally defined by the centerless rim. The centerless wheel assembly may also include a centerless ring gear coupled to the centerless rim such that rotation of the centerless ring gear causes a corresponding rotation of the centerless rim. The centerless ring gear may include a second center point laying in a second plane generally defined by the centerless ring gear, and the first plane may be generally parallel to the second plane. Additionally, the centerless ring gear may be shaped to interface with a drive gear that drives the centerless ring gear.

A rim (5) for a bicycle wheel having a body (20) with a substantially annular extension with a radially outer portion (22) shaped for coupling with a tire is disclosed. The radially outer portion (22) has a hole (39) for an inflation valve. The radially outer portion (22) also includes, at the hole (39) and/or in an area proximal to the hole (39), at least one cross section having a different shape from that at an area distal from the hole, so as to form at least one second surface discontinuity (35) along the annular extension of the radially outer portion (22). The second discontinuity (35) makes it easier to assemble to wheel and allows an optimal coupling to be made between the rim (5), inflation valve, and tire, in the case of a tubeless wheel, and between rim (5), air chamber and tire, in the case of a wheel with an air chamber.

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.
