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.

The present disclosure relates to a hub apparatus and associated charging systems. In some embodiments, the hub apparatus includes (1) a housing assembly defining an internal space; (2) a shaft positioned to extend through the housing assembly; (3) a stator assembly fixedly coupled to the shaft; (4) a side cover fixedly coupled to the shaft and rotatably coupled to the housing assembly, the side cover having a base portion and a mating portion extending from the base portion; and (5) a pair of first connectors positioned through the mating portion. Each of the first connectors comprising a terminal end and a contact portion. The terminal end is electrically coupled to a battery assembly via a wire bundle fixedly coupled to the side cover. The contact portion is configured to electrically couple to an external power source so as to charge the battery assembly through a wired connection.

An ultrasonic diagnostic apparatus according to an embodiment includes a body, a plurality of wheels, and control circuitry. The body sends and receives ultrasonic waves to generate an ultrasonic image. The plurality of wheels supports and moves the body. The assist wheel is electrically driven, and assists movement of the body. The control circuitry is configured to control switching between grounded and ungrounded of the assist wheel to a floor.

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.

An air deflector that is at least partially disposable within a tubeless tire of a bicycle wheel includes a body. The body includes at least one wall defining an air input end and an air output end of the body. The body is attachable to a valve of the tubeless tire at the air input end, such that when air is introduced into the body via the valve, at least some of the air is deflectable by one or more walls of the at least one wall out of the body at the air output end.

A logo printed wheel apparatus for customizable advertising and self-expression includes a central hub having a plurality of mounting apertures extending therethrough. The mounting apertures are configured to mount to a vehicle a plurality of spokes coupled to the central hub. Each spoke radially extends from the central hub and has an outer surface. A plurality of logos is coupled to the outer surface of each of the plurality of spokes. An outer rim is coupled to the plurality of spokes. The outer rim is configured to receive a tire.

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.

The present invention provides a single-point reinforcing structure for spoke of bicycle rim which includes a left side wall and a right side wall continuously extending along a circumferential direction of the bicycle rim. The left side wall and right side wall are formed at the left side and the right side of the bicycle rim respectively and are symmetrical to each other. A surface of the left side wall and a surface of the right side wall opposite to each other are connected through a connecting wall. The upper ends of the left side wall and the right side wall extend upward toward a direction close to a symmetry axis and are connected. The left side wall, the right side wall, and the connecting wall are surrounded to form an upper cavity of the bicycle rim. A plurality of connecting holes are arranged on the upper cavity.

The present disclosure relates to structures and associated systems for connecting a hub apparatus to a wheel. In some embodiments, the hub apparatus includes (1) a housing assembly having an outer radius; and (2) a mounting portion circumferentially provided on at least one side surface of the housing assembly. The mounting portion is formed with a plurality of coupling structures configured to couple the hub apparatus to a wheel rim. The mounting portion defines a first radius smaller than the outer radius.
