The present invention relates to an electronic braked-integrated in-wheel motor driving device. According to one embodiment of the present invention, an apparently complicated driving device structure, which is formed due to the installation of a brake, can be avoided, and a product appearance of a wheel-chair, to which the in-wheel motor driving device is applied, can be simplified, whereby the driving device improves the visual appearance as well as the brake function and can thus enhance production competitiveness.

A brake device, configured to be installed directly on a driving axle or through a hub, wherein said device includes a first brake disc joined to the axle sharing rotary motion, a first container disc and a second container disc configured to be moved in the axial direction of said axle. The container discs are positioned on each side of the brake disc, such that both are configured to be moved in the axial direction towards the linings of the first brake disc and to exert a pushing pressure thereon, producing the braking of the brake disc and, therefore, of the driving axle whereon it is assembled. Furthermore, the container discs comprise an inner circuit configured to accommodate the passage of a coolant configured to cool them.

In some examples, an assembly includes a rotor drive key configured to be positioned over a wheel boss defined by a wheel. A drive key body defines a trough configured to receive the wheel boss. An inner surface of the drive key body is configured to establish a conforming contact with an outer profile of the wheel boss and oppose relative motion of the rotor drive key in a radial direction of the wheel. The rotor drive key includes a tab having a tab aperture configured to receive a fastener extending in an axial direction of the wheel and engaging the wheel boss.

In some examples, a brake system includes a piston configured to cause a compression of a disc stack. The piston includes a piston body configured to compress a cap face of a piston cap against a pressure plate to cause the compression of the disc stack. The cap face may define a convex surface. The piston cap may be configured such that the convex surface reduces it curvature when the cap face is compressed against the pressure plate. In examples, the piston cap is configured to elastically deform to cause the cap face to reduce the curvature when the cap face is compressed against the pressure plate.

A powered axle for a work vehicle with a dual wheel arrangement includes an axle housing, an axle hub mounted to the axle housing, and an output hub having opposite axial ends supported by one or more wheel bearings for rotation about the axle hub along a rotation axis. An electric drive is disposed, at least in part, within the axle housing, and a hub gear set is disposed, at least in part, within the axle hub and configured to transmit power from the electric drive to the output hub for rotation of the dual wheel arrangement. A wheel brake disposed radially between the axle hub and the output hub and axially between the ends of the output hub is configured to selectively permit and arrest rotation of the output hub.

In human-powered vehicles, e.g., bicycles, etc., it is customary to use drum brakes, disc brakes or shoe brakes. Each of the braking systems has different advantages in terms of braking effect, system costs, ease of maintenance, etc. A brake unit with a modified structure for a vehicle is provided. For this purpose, a brake unit 14 for a vehicle 1 is disclosed, having a housing 15, having a brake body device 23, wherein the brake body device 23 supports a stationary brake partner of a brake apparatus 12 for the vehicle 1, wherein the housing 15 and/or the brake body device 23 defines a main axis H, having an actuator for moving the brake body device relative to the housing 15 in order to generate a braking force, wherein the stationary brake partner is formed as a brake disc 13.

Torque tubes with better total failure performance is provided. The torque tube comprises a plurality of reinforcement members made from a second material with a higher temperature strength than the first material. In preferred embodiments, the reinforcement members are tungsten rods. The reinforcement members are located concentrically around a central axis of the torque tube and each reinforcement member spans a center line of a central tube of the torque tube and spans a majority of a longitudinal length of the torque tube. In preferred embodiments, the reinforcement members are drive keys.

A half cap wear clip may comprise: a wear face configured to interface with a torque bar; a first flange disposed on a first side of the wear face and a second flange disposed on a second side of the wear face, the second side opposite the first side; and a deformable feature disposed on a first end of the first flange and the second flange and the wear face, the deformable feature configured to permanently deform a first distance in response to a load on the wear face exceeding a load threshold.

An example rotational joint assembly for a robotic medical system, the rotational joint assembly comprising at least one arm segment and a rotational joint provided at one end of the arm segment. The rotational joint is to allow the arm segment to rotate about a rotational axis. The rotational joint comprising a brake to lock rotation of the arm segment at the rotational joint and an actuator to selectively engage or disengage the brake. The actuator comprising a cam having two stable regions separated by two transition regions, the two stable regions comprising a first stable region corresponding to engagement of the brake and a second stable region corresponding to disengagement of the brake.

A gear system includes a gear unit and an electromagnetically actuable brake, the brake having a coil core that is connected to a brake surface part in a torsion-resistant manner. The brake surface part is connected to a bearing flange, its bearing mount in particular delimiting a free space. The bearing flange is connected to a cover part which is connected to a housing part of the gear unit, and a shaft is supported in the housing part via at least one bearing. A driver is connected to the shaft in a torsion-resistant manner, the driver having an external tooth system that is in engagement with an internal tooth system of a brake pad carrier such that the brake pad carrier is connected to the shaft in a torsion-resistant yet axially displaceable manner. An armature disk, which is disposed in a torsion-resistant yet axially displaceable manner with respect to the coil core, is situated between the coil core and the brake pad carrier.
