A strut type suspension device has a retractable strut (111) that connects to an upper portion of an in-wheel motor drive device (10) so as not to relatively move; and a swingable lower arm (116) that is coupled to a lower portion of the in-wheel motor drive device in any direction, and permits vertical swinging of the in-wheel motor drive device and also permits steering of the in-wheel motor drive device about a steering shaft (S) that passes through a coupling point (119) between the lower arm (116) and the in-wheel motor drive device. An axis (M) of the motor portion (21) of the in-wheel motor drive device is arranged above a height of the coupling point (119) of the lower arm (116).

A bicycle hub assembly comprises a hub axle, a hub body, and a sprocket support body. The hub body includes a first spoke-mounting portion, a second spoke-mounting portion, and a first axial length. The first axial length is defined between a first axially outermost part of the first spoke-mounting portion and a second axially outermost part of the second spoke-mounting portion in an axial direction with respect to a rotational center axis. The first axial length is equal to or larger than 55 mm. The sprocket support body is rotatably mounted on the hub axle about the rotational center axis. The sprocket support body includes at least ten external spline teeth configured to engage with a bicycle rear sprocket assembly. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface.

The first axial length is defined between a first axially outermost part of the first spoke-mounting portion and a second axially outermost part of the second spoke-mounting portion in an axial direction and is equal to or larger than 55 mm. The sprocket support body includes a plurality of external spline teeth. The plurality of external spline teeth includes a plurality of external-spline driving surfaces. The plurality of external-spline driving surfaces each includes a radial length defined from a radially outermost edge to a radially innermost edge. A total of the radial lengths of the plurality of external-spline driving surfaces is equal to or larger than 7 mm.

A kingpin unit bearing steerable drive axle for a powered wheel of a vehicle may include a steering knuckle having a first side and a second side, and a unit bearing configured to support a wheel and operatively connected to the first side of the steering knuckle. An axle housing is operatively connected to the second side of the steering knuckle, and the axle housing has an upper arm and a lower arm. A first kingpin connects the upper arm of the axle housing to the steering knuckle; and a second kingpin connects the lower arm of the axle housing to the steering knuckle. The steering knuckle and the axle housing are configured to receive a powered axle shaft to drive the unit bearing.

An individually phased pawl drive mechanism includes a plurality of pawls each including a plurality of protrusions forming at least one slot between a corresponding pairing of the plurality of protrusions; a pawl carrier member sized and configured for receipt of the plurality of pawls; a drive ring carrier member including a plurality of radially displaced teeth; wherein rotation in one direction causes a first one of the plurality of radially displaced teeth to engage a first one of the plurality of pawls, the primary pawl; and wherein continued rotation is permitted if the drive force is sufficient to cause deflection of the pawl carrier member relative to the drive ring carrier member, thereby causing one or more subsequent ones of the plurality of secondary pawls each to be brought into engagement in succession with a corresponding one of the plurality of radially displaced teeth.

A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, a first ratchet member, a second ratchet member, and a sliding member. The hub shell includes at least one first tooth. The sprocket support body includes a first helical spline. The first ratchet member comprises at least one first ratchet tooth and a second helical spline engaged with the first helical spline. The second ratchet member comprises at least one second ratchet tooth and at least one second tooth. The at least one second ratchet tooth is engageable with the at least one first ratchet tooth. The at least one second tooth is engaged with the at least one first tooth. The sliding member is provided between the sprocket support body and the second ratchet member in an axial direction parallel to a rotational axis. The sliding member includes a non-metallic material.

An integrated wheel end coupler for replacing an OEM coupler is disclosed. Since the current device is a replacement part for the OEM actuator, it has the same overall external dimensions and mounts in the vehicle in the same manner as a replacement OEM actuator. The coupler has a ring gear with splines dimensioned to mesh with splines on the half-shaft and hub. Preferably, the ring gear includes an internal insert positioned between the half-shaft and hub that prevents slippage off of the splines. The ring gear is located so that the splines on both the hub and the half shaft are locked together mechanically and they spin at the same rate of speed. The coupler also includes pins to receive and close off the airlines associated with the OEM actuator being replaced, and a grease fitting that allows the application of grease to the coupled parts.

A reinforcement for a hub ratchet base comprising a chain-ring and a ratchet ring. The chain-ring is made of an aluminum material having a chain-ring socket and an assembly shaft. The ratchet ring is made of a metal material with high hardness which can be the titanium alloy material or the chrome-molybdenum steel material. The ratchet ring has an engaging slot corresponding to the assembly shaft of the chain-ring. There are at least three connecting slots disposed on the ratchet ring for accepting at least three ratchet members and at least three corresponding elastic members. Each of the connecting slots of the ratchet ring has a pivoting portion on an end for engaging with a ratchet member and an engaging portion on another end for engaging with an elastic member such that the elastic member pushes against a bottom portion of the ratchet member.

The invention refers to the internal connection of a rear bicycle wheel hub (1) comprising a cylindrical body (2) that surrounds an axle (3), where a proximal end (2b) of the body (2) is attached to a freehub body (4) that surrounds a freewheel system (6). A connecting mechanism (5) between the body (2) and the freewheel system (6) of the freehub body (4) is characterized in that it comprises a connecting crown (7) coupled to an inner surface (2c) of the body (2) that connects with a ring (6a) in the freewheel system (6) and an elastic ring (8) seated in a circular recess (9) on a lateral surface (7c) of the connecting crown (7) so that it can expand towards the inner surface (2c) of the body (2) and fix the connecting crown (7) inside the body (2).
