Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.

The bicycle hub assembly includes a hub axle, a hub body, a bearing unit, a lock member, and a tool engagement member. The bearing unit is configured to rotatably support the hub body around the hub axle with respect to the rotational center axis. The bearing unit includes an outer race, an inner race and a plurality of rolling members. The lock member prevents the inner race of the bearing unit from rotating relative to the hub axle. The tool engagement member is configured to rotate the inner race of the bearing unit relative to the hub axle.

A drive device for driving and rotating a wheel includes an axle shaft, a hub to which rotation of the axle shaft is conveyed, a plurality of fasteners for securing the wheel to the hub, a wet brake, a housing, an oil seal, and a cover. The wet brake is configured to restrain the rotation of the axle shaft. The housing accommodates the axle shaft and the wet brake. The oil seal is disposed between the housing and a part of the hub that is disposed inward of the fasteners in a radial direction of the hub. The cover has an annular shape. The cover is disposed in a space formed between the hub and the housing, and is secured to the housing. The cover is configured to cover the plurality of fasteners.

A first labyrinth seal includes: a drive shaft side annular protrusion that is formed on one of the slinger and the drive shaft seal plate and that protrudes over the circumference of the drive shaft; and a drive shaft side annular groove that is formed on the other of the slinger and the drive shaft seal plate and that recedes over the circumference of the shaft. A second labyrinth seal includes: a carrier-side annular protrusion that is formed on one of the carrier seal plate and the planetary carrier and that protrudes over the circumference of the shaft of the planetary carrier; and a carrier-side annular groove that is formed on the other of the carrier seal plate and the planetary carrier and that recedes over the circumference of the shaft.

An axle assembly having a spindle, an axle shaft, and a wheel end assembly. The wheel end assembly includes a hub and a gear reduction unit. The gear reduction unit includes first and second side gears, a case, and a pinion gear that is rotatably disposed on a pinion pin. The case is rotatable with the hub.

Example bicycle sprocket assemblies are described herein. An example sprocket assembly includes a cassette formed by a plurality of sprockets arranged in increasing diameter order from a first end to a second end of the cassette opposite the first end. The cassette has a passageway extending between a first opening in the first end and a second opening in the second end to receive a driver hub. An outboard portion of the passageway is formed between a midpoint of the cassette and the first end of the cassette. The cassette further includes a torque transmitting profile located within the outboard portion of the passageway to interface with the driver hub. The sprocket assembly also includes a bushing to be disposed within the second opening to form a non-torque transmitting interface between the second end of the cassette and the driver hub.

In an in-wheel motor drive device, a speed reduction part is a parallel shaft gear reducer that includes a plurality of gear shafts extending in parallel to one another. One of the gear shafts is coupled with the rotation shaft of the motor part, the other one of the gear shafts is coupled with the wheel hub of the wheel hub bearing part. Remaining gear shafts decelerate the rotation of the motor part and transmit it to the wheel hub. The motor drive device includes a parking gear attached to any of the gear shafts. The parking pawl has a projection portion engaged with a recess portion of the parking gear. A movement member enables a parking pawl to move between a locking position engaged with the recess portion and an unlocking position not engaged therewith. The parking gear, the parking pawl, and movement member are housed inside a housing.

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.

A corner module of a vehicle includes: a suspension configured to be coupled to a vehicle body; a case configured to be coupled to the suspension and configured to be to be supported on the vehicle body via the suspension; an in-wheel motor disposed inside the case; a steering motor disposed inside the case; a first power transmission mechanism configured to connect the in-wheel motor and a vehicle wheel and configured to transmit a rotating force of the in-wheel motor to the vehicle wheel to drive the vehicle wheel; and a second power transmission mechanism configured to connect the steering motor and the vehicle wheel and configured to transmit a rotating force of the steering motor to the vehicle wheel to steer the vehicle wheel.

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 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.
