A nonpneumatic tire includes a tread portion, an upper ring, and a plurality of spokes extending radially downward from the upper ring. Each spoke is configured to carry a load while in tension and while in compression. The upper ring and the plurality of spokes are part of a unitary component constructed of a single material. Each spoke terminates at a lower end having a spoke mount with an opening configured to engage a corresponding hub mount. Each spoke is under substantially no tension when the tread portion is not in contact with a ground surface and when each spoke mount is disengaged from its corresponding hub mount. Each spoke is under tension when the tread portion is not in contact with the ground surface and when each spoke mount is engaged with its corresponding hub mount.

A bicycle wheel hub for mounting a brake disc in relation to a spoke-holding flange. The hub has a connection portion with a first annular sector that is axially external with respect to the spoke-holding flange and a second annular sector that is axially external with respect to the first annular sector. A circumferential groove axially arranged between the first and the second annular sectors.

A vehicle wheel, including a rim, a hub, and a plurality of spokes, a first anchor to connect one of the spokes to one of the rim and hub at a connection interface. One of the spokes is pre-tensioned by a pre-tensioning means. The first anchor may be manipulated between: (i) a released orientation where the connection interface is longitudinally released from the spoke to permit independent longitudinal displacement therebetween; and (ii) an engaged orientation where the connection interface is longitudinally connected to said spoke to limit independent longitudinal displacement between the two and to maintain the pre-tension of said spoke. The pre-tensioning means is discreet from the first anchor.

A wheel rim assembly includes a hub with a case and two flanges are formed on two ends of the case. Multiple spoke units are connected between the two flanges of the hub and the inner periphery of the rim. Each spoke unit includes a first connection member and the first end of an X-shaped spoke extends from the first connection member. Each first connection member includes a first recessed area and a second recessed area respectively defined in the outside and the inside thereof. The second recessed area is matched with the flange corresponding thereto. Each first connection member includes an engaging recess and a protrusion. The protrusion of one first connection member is engaged with the engaging recess of the next first connection member. Two covers are respectively connected two ends of the hub. The second end of each spoke is inserted into reception recess of the rim.

A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.

Disclosed herein are systems and techniques for producing complex components using a reinforced thermoplastic material. The complex components can include contoured or curved outer surfaces, and in some cases define a cavity. In certain examples, one or more thermoplastic materials are arranged to form a wheel component, such as that adapted to define a rim of the bicycle. Thermal bonding can be used to join multiple reinforced thermoplastic materials to one another in order to form a cavity of the wheel component or other complex shape. In certain examples, a portion of a tooling assembly can be pressurized to maintain a shape of the cavity during thermal bonding and cooling. This can remove the need for a sacrificial bladder or other structure that would maintain the shape of the cavity, allowing for a seamless final component, optionally absent indicia of bladder exit or other seams.

A wheel with high strength flexible spokes of the present invention, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength. The wheel includes a nipple within the rim that receives the high strength spoke and allows for flexibility in adapting the spoke to wheels having differing shapes and sizes.

To provide a bicycle hub unit and a bicycle wheel assembly that allow a wheel unit to be appropriately coupled to a hub body, a bicycle hub unit is coupled to a rotary body to which a brake is applied by a brake device. The bicycle hub unit includes a hub body that rotates around a hub axle and a rotary body coupling portion that couples the rotary body to the hub body. The hub body includes a first joint portion and a second joint portion. The first joint portion includes an external thread coupled to an internal thread of the wheel unit. The second joint portion is coupled to a restriction member that restricts relative rotation of the first joint portion and the wheel unit.

Disclosed is an actuator generating haptic sensations, the actuator having a spherical rotor driven by a magnetic force vector created around the same, a stator having a space corresponding in shape to the spherical rotor defined therein to allow the spherical rotor to be positioned in the space and having a portion of an upper part of the spherical rotor exposed, at least three rotation-driving coils formed in the stator at a given distance from each other to provide the magnetic force vector to the spherical rotor, and a driving unit independently controlling electric current supplied to each of the rotation-driving coils to create the magnetic force vector.

Spokes of a wheel contain: a wheel rim, a hub, multiple screwing segments, and multiple screw elements. The respective spoke is made of chrome molybdenum (CrMo), and the respective spoke includes a through hole passing therethrough so as to form a seamless alloy steel pipe. The respective spoke includes a first connection segment and a second connection segment, the first connection segment has a first threaded section, and the second connection segment has a second threaded section so that the first threaded section is screwed with the respective screw element of the hub. The respective screw element of the hub has an orifice, such that the first threaded section is inserted through the orifice to screw with the respective screw element on an inner wall of the hub, and the second threaded section is screwed with the respective screwing segment of the wheel rim.
