The brake disc release device comprises: an actuating mechanism; a gear connected to a first end of the actuating mechanism; a first slider capable of sliding along a first guide piece and comprising a rack portion for engagement with the gear and a first wedge portion; a second slider capable of sliding along a second guide piece and comprising a second wedge portion for engagement with the first wedge portion of the first slider; and a pulling cable having a first end connected to the second slider and a second end connected to the brake disc.

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.

Methods and systems for a vehicle transmission are provided herein. The vehicle transmission includes an input interface configured to mechanically couple to a motive power source. The vehicle transmission further includes a first disconnect device releasably mechanically coupling a first output to a first drive axle and a second disconnect device releasably mechanically coupling a second output to a second drive axle.

An electric parking brake for a vehicle brake system includes a caliper, a piston, a spindle, an adjuster nut, a ring-like member affixed to the piston, and a biasing member. The piston may be disposed within a cavity of the caliper. The spindle is configured to drive the axial movement of the adjuster nut between a retracted position and an extended position via a threaded engagement wherein the adjuster nut is disposed within the piston. The biasing member may be disposed between the ring-like member and the adjuster nut so that, as the adjuster nut moves from an extended position to a retracted position which corresponds to a control signal, the biasing member urges the piston away from the rotor.

A park brake system for adjusting a tension in a brake cable that is coupled to a park brake. The park brake system can include a driver that is communicatively coupled to a microcontroller, and an actuator that is rotatably displaceable by operation of the driver. An equalizer assembly can be linearly displaced along the rotating actuator to adjust a tension in the brake cable. The microcontroller can monitor a current being drawn by the driver as the driver is operated, and generate instructions to cease operation of the driver upon the current reaching a predetermined current threshold that corresponds a maximum force that is to be applied by the park brake. The microcontroller can also, when the park brake is being released from a set position, count pulses outputted by an encoder in connection with determining whether the park brake has reached a running clearance position.

An axle disconnect assembly, including: a housing and a clutch a shaft with first splines; a sleeve including second splines non-rotatably connected to the first splines, and axially extending teeth; a shift lever including at least one pivot pin, a first end connected to the sleeve, and a second end; and an actuation assembly including an actuation shaft engaged with the second end of the shift lever, and an actuator. In a connect mode, the teeth are non-rotatably connected to a power output. In a disconnect mode, the sleeve is rotatable with respect to the power output. To shift from the disconnect mode to the connect mode: the actuator rotates the actuator shaft; the actuator shaft pivots the shift lever around an axis of the at least one pivot pin; and the first end of the shift lever displaces the sleeve, with respect to the shaft, in an axial direction.

A pad return spring for a caliper body. The caliper body has an elongated element connecting bridge connecting a first elongated wheel-side element to a second elongated wheel-side element and having a middle connecting bridge defining an outer middle bridge side, an inner middle bridge side, a middle bridge disc inlet side, and an opposite middle bridge disc outlet side. The pad return spring has a first and a second pad retraction elements, each defining a middle stretch, a first side stretch influencing the first pad, and an opposite second side stretch influencing the second pad to move the first and second pads away from the first and second braking surfaces at the end of a braking action, and an elongated connecting element connecting the first and second pad retraction elements to each other, and an anchoring device to removably restrain the pad return spring to the middle connecting bridge.

An assembly has two pads having a support plate and a friction material coating, each pad being accommodated in a pocket of a caliper and positionable on a side of a brake disc. At least one spring applies an elastic bias on the pads so as to elastically bias the pads away from the brake disc. The support plate has a plate coupling portion having an inner lower edge, facing the brake disc in a radially inward direction or towards the rotation axis, an inner upper edge, facing the brake disc in a radially outward direction or opposite to the rotation axis, the inner upper edge continuing on a direct upper surface according to the axial direction (A-A), forming an upper spring-coupling plate portion edge. The spring is always in contact exclusively with the inner lower edge and the upper spring-coupling plate portion edge.

The present invention concerns a brake actuation mechanism for a disc brake, in which a translational movement in the direction of the brake disc leads to a rotation of an input element of an adjustment device, the input element of the adjustment device being designed as part of a ball screw drive. Furthermore, the invention concerns a disc brake with such a brake actuation mechanism.
