Disclosed is a brake system for a railway vehicle, including linings each having at least one positioning member for mechanically fastening the linings in a predetermined position on the system with respect to a disc of the vehicle and a bearing face for tightly gripping the disc under the action of an actuator of the system, and at least one return member for separating the linings from the disc in order to release it when the linings are freed from the action of the actuator; each lining has at least one fastening member formed on an edge, the return member has two opposite end lugs connected to one another by an elastic portion and each mechanically fastened with a the fastening member, and the system is configured such that the fastening members and the end lugs are situated at a distance from the at least one positioning member.

A brake cylinder includes a locking device for mechanical brake force locking, in particular for rail vehicles, and a service brake piston which can be axially moved inside a housing, which can be moved by applying a pressure medium thereto, and which is coupled to a piston tube, said piston tube being provided with a non-self-locking thread which is engaged with a threaded nut which is rotatably mounted in the housing, and the locking device cooperating with toothing of the threaded nut. The brake cylinder is designed such that the locking device comprises one or more pawl(s), a control piston, an emergency release tappet, and a locking element of the emergency release tappet.

A lifting-device brake system includes at least one brake assembly configured to be activated by a spring force. The at least one brake assembly is configured to achieve a braking effect. At least one piston/cylinder assembly is configured to be actuated by a hydraulic or pneumatic pressure via which the braking effect achieved by the at least one brake assembly can be reduced by at least partially overcoming the spring force. A hydraulic or pneumatic assembly is configured to provide the hydraulic or pneumatic pressure to actuate the at least one piston/cylinder assembly. The hydraulic or pneumatic assembly comprises an apparatus configured to maintain the hydraulic or pneumatic pressure applied to the at least one piston/cylinder assembly.

A brake (10) includes a housing (12) formed from a first housing portion (14) capable of receiving a second housing portion (16). The first housing portion (14) houses a piston (18) and a plurality of springs (20), and the second housing portion (16) houses an alternating arrangement of discs (52) for enacting a braking function. The second housing portion (16) further includes torque pin holes (80) for receiving torque pins (82) therein. Each torque pin (82) is secured with a plug (84) to secure stationary discs (54A, 54B, 54C) in place. The stationary discs (54A, 54B, 54C) have extending ears (74) positioned between torque pin grooves (76), which further receive the torque pins (82).

In some examples, an assembly includes a vehicle wheel that defines an interior and an exterior surface, where the interior surface defines a first protrusion and a second protrusion. The first protrusion defines a first aperture extending in a substantially axial direction. The assembly further includes a rotor drive key on the interior surface, the drive key defining a first and second feature, and the first feature defines a second aperture extending in the substantially axial direction and is configured to align with the first aperture. The assembly includes a fastener configured to be inserted through the first and second aperture in the substantially axial direction to attach the key to the interior surface of the wheel, where the second aperture is configured to form a threaded connection with an end of the fastener. When the fastener is tightened via the threaded connection, the second feature engages the second protrusion.

A hydraulic power take-off is provided for use with industrial drives that deliver power to industrial equipment. The hydraulic power take-off has a brake disconnect system that can manually release a brake assembly to allow low-effort rotating of the industrial equipment components to facilitate servicing.

A parking brake unit of a brake device for braking a wheel includes a first piston having a first engaging part on an inner circumference thereof, the first piston being configured to move in first direction by pressure of the hydraulic fluid supplied to a pressure chamber defined in the back thereof, a first biasing member configured to bias the first piston in second direction, opposite to the first direction, a second piston slidably provided on the inner circumference of the first piston, the second piston having a second engaging part on an outer circumference thereof, and an engaging member configured to cause the first engaging part and the second engaging part to engage with each other, in which the second piston causes a brake lining to move in direction bringing the wheel to be in a braking state, when the first piston moves in the second direction.

A work vehicle drive assembly has a bimodal clutch module that includes a pressure plate, a module housing containing first and second cavities located on opposing sides of the pressure plate, and an actuator. The actuator is controllable to move the pressure plate along a working axis of the clutch module. A clutch member is installed in a selected one of the first and second cavities. The clutch member is (i) engaged by movement of the pressure plate along the working axis in a first direction when the clutch member is installed in the first cavity and (ii) disengaged by movement of the pressure plate along the working axis in the first direction when the clutch member is installed in the second cavity.

A braking system is proposed for a vehicle, in particular a lightweight vehicle, in particular a pedal cycle, comprising a brake device, a mechanical urging device, and a hydraulic urging device, wherein the mechanical urging device and the brake device form a parking brake device, and the hydraulic urging device takes the form of a hydraulically actuable release device for the parking brake device.
