A hub motor assembly includes a hub axle, a hub shell, a motor unit, a cycloidal speed reducer, and a one-way clutch unit. When an output shaft of the motor unit rotates in a first direction about an axial line, a cycloidal wheel of the cycloidal speed reducer is driven to produce an eccentric cycloidal motion relative to the axial line, to thereby drive rotation of the hub shell in the first direction. When the output shaft rotates in a second direction opposite to the first direction, the hub shell is prevented from rotating with the output shaft.

An axle assembly includes a spindle to receive a drive shaft having a rotational input about an axis and a wheel hub rotatably supported by at least one roller bearing disposed on the spindle. A tire inflation system defines a spindle gas passage to route pressurized gas from an onboard source through the spindle. The tire inflation system includes a seal chamber between the spindle and wheel hub to transfer gas from the spindle to the wheel hub, and a hub gas passage in fluid communication with the seal chamber is arranged to route the pressurized gas to a tire. A lubrication system having a reservoir is located axially outboard of the seal chamber and at least one hub lubricant passage routes lubricant between the reservoir to a roller bearing located axially inboard of the seal chamber. The hub lubricant passage routes lubricant radially outward of the seal chamber.

A wheel/hub assembly includes an axle shaft, a wheel, and a hub supporting the wheel on the axle shaft. The wheel/hub assembly has a target resonant frequency of vibration. A tuned mass-spring damper is vibrationally coupled to the wheel/hub assembly, and has a counteracting resonant frequency of vibration that is predetermined with reference to the target resonant frequency of vibration.

Provided are an in-wheel driving device and a vehicle including the same. According to exemplary embodiments of the present disclosure, the in-wheel driving device includes: a wheel bearing including a hub forming a body; a resolver sensor provided in the inside of the wheel bearing, and including a resolver rotor and a resolver stator; and a wheel sensor partially provided in the inside of the wheel bearing, and detecting a rotation of the resolver rotor.

The present disclosure in at least one embodiment provides a corner module for a vehicle, including a front-wheel corner module configured to drive a front wheel and including a front-wheel inwheel motor installed on the front wheel to generate a driving force and a friction braking device configured to generate a braking force on the front wheel, a rear-wheel corner module configured to drive a rear wheel and including a rear-wheel inwheel motor installed on the rear wheel to generate a driving force, a driving information detector configured to detect driving information of the vehicle, and an electronic control unit configured to control the front-wheel corner module to form a friction braking force by using the driving information and to control the rear-wheel corner module to form a regenerative braking force, wherein the front-wheel corner module uses the front-wheel inwheel motor that is provided with a lower specification than the rear-wheel inwheel motor to save the manufacturing cost, and the rear-wheel corner module has no friction braking device installed so that the rear-wheel inwheel motor is undamaged by heat.

Hub bearing assembly for a vehicle wheel, the assembly having an axial tubular appendage capable of being inserted into a central hole of a wheel of the vehicle, and wherein the tubular appendage has a radially outer surface of substantially cylindrical shape; a collar of cylindrical shape being mounted on the tubular appendage so as to cover a second centring section of the radially outer cylindrical surface, and having an insert of metallic material and an inner coating layer which at least partially covers the insert and is formed on the insert by galvanizing.

A wheel structure with a built-in reducer and motor is provided. As the driving wheel in a rudder wheel, which has a high degree of integration and significantly reduces the overall height of the rudder wheel while maintaining high speed and acceleration. The wheel structure includes a wheel coupled to a reducer, a drive motor connected to the reducer, and the reducer.

A system for locking a rotatable shaft may include a base member couplable to the rotatable shaft and rotatable about a rotation axis of the rotatable shaft through a plurality of angular positions, the base member comprises two or more curved slots; two or more pins positioned with respect to the base member such that at least one of the two or more pins is aligned with at least one of the two or more curved slots of the base member for any angular position of the base member; and an actuator to displace at least one of the two or more pins to removably insert at least one of the two or more pins into at least one of the two or more curved slots.

A heat shield assembly for a braked aircraft wheel is provided. The heat sheild assembly includes a heat shield and at least one spacer having both a main body projecting from an outwardly-facing surface of the heat shield and a clamping element of generally cylindrical shape projecting from the body and passing perpendicularly through an opening in the heat shield. The clamping element can include an enlarged free end so as to co-operate with the body to form an annular groove engaged with the opening in the heat shield.

An internal-meshing planetary gear device includes an internally toothed gear provided with internal teeth and is fixed to an outer ring. A planetary gear is provided with external teeth which partially mesh with the internal teeth. A plurality of internal pins is respectively inserted into a plurality of internal pin holes formed on the planetary gear revolve within the internal pin holes and rotate relative to the internally toothed gear. An inner ring includes a first inner ring and a second inner ring, which are opposite each other in a direction parallel to a rotation axis and have opposite surfaces that come in contact with each other. The first inner ring has a plurality of holding holes, through which the plurality of internal pins respectively penetrate in the direction parallel to the rotation axis. Each of the plurality of internal pins is held in the inner ring and is rotatable.
