A hub built-in type drive axle includes one hub housing assuming a role of an external race of a constant velocity joint and a role of a wheel hub simultaneously, wherein the outboard constant velocity joint center is positioned within the full length of the hub housing, and a structure in which a bear housing and a boot assembly ring, including a boot, do not rotate whether the driveshaft 1 rotates is maintained so that performance may be improved, durability may be enhanced, and noise may be minimized.

An apparatus and methods are provided for a rear portal trailing arm assembly for a vehicle rear suspension. The trailing arm assembly comprises a CV joint hub for coupling with a transaxle and a wheel hub for coupling with a rear wheel. A gear transfer case extends rearward from the CV joint hub to an axle case and functions similarly to a rear trailing arm. Forward mounts facilitate coupling the gear transfer case to the chassis such that the trailing arm assembly pivots vertically with respect to the chassis. A rearward mount facilitates coupling a strut with the gear transfer case to control the vertical motion of the rear wheel. Multiple gear assemblies are meshed within the gear transfer case. An axle is coupled with the meshed gear assemblies and housed within the axle case, such that torque applied to the CV joint hub is communicated to the wheel hub.

A bicycle freewheel assembly is provided which is capable of being readily and reversibly switched from fixed-gear to freewheel operation, without the necessity of removing the wheel from the bicycle. The freewheel assembly is mountable on pre-existing freewheel hubs.

A disk brake apparatus of an in-wheel driving system may include: an in-wheel driving device having a rotor and stator, and positioned within a wheel; a first torque member installed on the stator, and configured to support one side portions of a pair of brake pads; a second torque member spaced apart from the first torque member, and configured to support the other side portions of the brake pads; and a caliper body having one side portion coupled to the first torque member and the other side portion coupled to the second torque member, and configured to press the brake pads toward a wheel disk.

Provided is a vehicle power device (1) including: a wheel bearing (2); and a driving motor (3) that can rotationally drive an outer ring (4) as a rotary ring. The vehicle power device further includes a bracket (24) attached to a knuckle (8) of a vehicle. The bracket (24) includes a bracket base portion (24a) and a bracket cylindrical portion (24b), the bracket base portion interposed between the knuckle (8) and an inner ring (5) wherein the inner ring (5) is removably fixed, the bracket cylindrical portion (24b) extending from the bracket base portion (24a) toward an outboard side. The driving motor (3) includes a stator (18) removably attached to an inner periphery of the bracket cylindrical portion (24b) and a rotor (19) attached to the outer ring (4) on an inner periphery of the stator (18).

Systems, methods, and other implementations described herein relate to a hub motor for a wheel of a vehicle. In one embodiment, the hub motor includes a cylindrical rotor and a cylindrical stator coaxially spaced from the cylindrical rotor along an axle. The cylindrical rotor includes a rotor attachment to selectively couple the cylindrical rotor to the axle. The cylindrical stator is disposed between the cylindrical rotor and the wheel and includes stator attachments to selectively couple the cylindrical stator to an outer wheel surface of the wheel. The cylindrical rotor and the cylindrical stator are selectively attachable to the axle and the outer wheel surface, respectively, without removing the wheel from the vehicle.

There is provided a wheel bearing sealing arrangement for a wheel bearing of a vehicle, comprising an outboard bearing having an outboard periphery intended to face away from a central longitudinal axis of the vehicle and an inboard periphery intended to face towards the central longitudinal axis of the vehicle, wherein the outboard bearing comprises a first race-forming part and a second race-forming part which surrounds the first race-forming part; an outboard seal arranged between the first race-forming part and an opposite part; and a safety washer pressed against the outboard periphery of the first race-forming part, wherein the outboard seal comprises a sealing part pressed against and in direct contact with the safety washer. There is also provided a vehicle comprising such a wheel bearing sealing arrangement.

A sensor is mounted to or embedded in a wheel hub. The sensor node includes a power source and a sensing device that detects and monitors at least one parameter associated with the wheel hub. The sensor node also includes a communication module that communicates via wireless communication signals and a processing device in communication with the sensing device and the communication module. The processing device collects data from the sensing devices, processes the data, and based on that processing, communicates information relating to the wheel hub to a remote server or network. A mesh network of multiple sensor nodes can be applied to multiple different wheel hubs on a vehicle and communicate with a central processing device. The processing device can thus monitor performance and/or operation of each wheel hub.

A control device is provided for a human-powered vehicle that includes a generator configured to output electrical power, an electric power storage device electrically connected to the generator, and a component having an actuator actuated by electrical power from at least one of the generator and the electric power storage device. The control device includes a controller electrically connected to at least one of the generator and the electric power storage device. The controller is configured to control an operation state of the component in accordance with information relating to at least one of an output state of the generator and a store state of the electric power storage device.

The rotor of an electric motor unit has a web portion partially enclosing the remainder of the unit and terminating in a circumferentially extending rim. The brake drum defines an engagement surface for drum brake linings, and has an outboard end defining a flange securable to the wheel hub. The brake drum also includes an open inboard end, partly covered over by a dust guard, and a circumferential wall extending between the outboard and inboard ends and surrounding the engagement surface. By way of keys and slots or recesses, a reinforcing ring interlocks the circumferentially extending rim of the web portion and the circumferential brake drum wall. The reinforcing ring is secured to the circumferentially extending rim and to the wall of the brake drum at a location disposed axially between the rim of the web portion and the brake drum lining engagement surface.
