A piston housing may comprise: a main annular ring defining a main bore; a torque takeout annular ring defining a torque takeout bore; a torque takeout arm extending from the main annular ring to the torque takeout annular ring and defining an aperture therethrough; and a structural rib disposed within the aperture and extending from the main annular ring to the torque takeout annular ring.

The invention concerns a brake assembly for a vehicle wheel, the brake assembly comprising: a braked member that is coupable or coupled to the vehicle wheel for a joint rotation therewith about a rotational axis, the braked member having friction linings that are arranged at an axial distance from one another; and a braking unit that comprises an actuator and at least two displaceable members, the displaceable members being positioned in between the friction linings, wherein the actuator is configured move the displaceable members axially apart from one another, thereby bringing each displaceable member into contact with one of the friction linings of the braked member.

An electromagnetic brake with a housing body and a coil unit, wherein the coil unit has a positive connection to the housing body, wherein the coil unit is positively connected to the housing body by means of a snap-fit connection, wherein at least one snap hook of the coil unit is supported on a web of the housing body.

An electromagnetic brake having a housing body, a friction disk, and at least one compression spring provided in the housing body, wherein the friction disk has a bayonet-type connection to the housing body, wherein the friction disk is secured against rotation relative to the housing body.

A braking arrangement includes a torque plate, a torque button, and a sacrificial bushing. The torque button comprises a head portion and a shaft portion, wherein the head portion is configured to extend at least partially into a torque pocket of an end plate of a brake stack and the shaft portion is configured to extend through an aperture disposed in a back leg of the torque plate. The bushing is configured to be removably coupled between the shaft portion of the torque button and the back leg of the torque plate.

A brake device including a first device having a shaft; a brake element having a first frictional brake surface and an engageable structure; a second device rotatable relative to the first device about a rotation axis, the second device including a second member having an opening, a second frictional brake surface, and a forcing member pre-tensioned to force the second frictional brake surface against the first frictional brake surface; and an actuator connected to the first device, the actuator including an engaging structure movable between a disengaged position, and an engaged position to brake relative rotation between the first device and the second device about the rotation axis; wherein the shaft is concentric with the rotation axis and passes through the opening.

In some examples, a drive insert for a drive slot of a brake disc includes a first insert member configured to cover a first surface of the drive slot, a second insert member configured to cover a second surface of the drive slot, and a bridge member configured to extend between the first insert member and the second insert member. The bridge member is configured to limit movement of the first insert member and the second insert member in a tangential direction of the brake disc when the bridge member extends from the first insert member to the second insert member. In some examples, the bridge member is configured to be in compression between the first insert member and the second insert member.

In some examples, a rotor drive key assembly configured to be positioned on a wheel includes an insert and a rotor drive key. The insert is configured to mate with a wheel boss of the wheel and mechanically connect the rotor drive key with the wheel boss. The rotor drive key is configured to mate with the insert such that the insert limits movement of the rotor drive key relative to the wheel boss in at least a radial direction of the wheel. In some examples, 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 drive insert comprises a clip and a retainer. The clip is configured to be slidable over a surface adjacent to a drive slot of a brake disc in a tangential direction of the brake disc. The retainer is configured to be slidable over the clip when the clip is positioned over the surface to secure the clip to the brake disc. In some examples, the clip may comprise a body section and first and second arms extending from the body section. The retainer may comprise first and second legs configured to contact the first arm and the second arm of the clip when the retainer is positioned over the clip. The first and second legs may be resiliently biased to provide an inward clamping force on the clip when the retainer is positioned over the clip.

In some examples, an assembly includes a rotor drive key configured to fit around a wheel boss defined by a wheel. The rotor drive key includes a support structure. The assembly further comprises a fastener configured to extend the wheel boss and the support structure in a substantially axial direction of the wheel when the rotor drive key fits around the wheel boss, where the fastener is configured to limit movement of the rotor drive key relative to the wheel boss. The fastener may be rotated to establish and/or increase a contact pressure between the fastener and the rotor drive key to help the fastener limit movement of the rotor drive key relative to the wheel boss.
