A method of cooling an aircraft brake including a brake pack and a reservoir in the form of a removable cartridge containing a coolant. The method includes vaporizing the coolant using heat energy from the brake pack.

A method for providing a clamping force generated by an automatic parking brake includes using a brake motor and a brake piston acting on a brake disk to generate the clamping force. The method guarantees a reliable function of the automatic parking brake even on a loss of clamping force due to a temperature change of the brake disk. The method also minimizes the load on components of the automatic parking brake. After a completed application of the automatic parking brake, a secondary application process is carried out as a function of an activation reaction of the brake motor.

A brake apparatus includes a coupling member configured to couple one end parts of a pair of link arms, an actuator mounted on the coupling member and configured to advance and retract an output member, a lever rotatably coupled to the output member and configured to rotate by advancing and retracting movements of the output member and a booster unit provided on at least one of the one end parts of the pair of link arms and configured to rotate the link arms with supporting portions as fulcrums by boosting a force transmitted by the rotation of the lever.

A brake piston is described which comprises a first tubular piston body portion and a second tubular piston body portion. The second piston body portion is connected to the first piston body portion and lies, in an axial view, radially completely inside the first piston body portion, thus forming an annular hollow space. Furthermore, a length of the second piston body portion along a piston longitudinal axis is at least 50% of a length of the first piston body portion. An inner circumferential surface of the second piston body portion comprises an anti-rotation contour which also forms an axial guide contour for a brake piston drive. Moreover, a method for manufacturing such a brake piston is explained. A brake caliper for a disk brake of a vehicle is also presented, which brake caliper comprises such a brake piston.

A system, and associated method, for reducing oxidation of a friction disk may include a braking assembly comprising the friction disk and a coolant loop coupled to the braking assembly, with the coolant loop being configured to circulate liquid coolant from the braking assembly. That is, the coolant loop may be configured to reduce the temperature of the braking assembly, thus reducing the rate/extent of oxidation of the friction disks and potentially enabling the concentration of oxygen around the braking assembly to be reduced.

Disclosed are an electronic caliper brake and an operation method thereof. The electronic caliper brake includes a carrier on which a pair of pad plates are installed to advance and retreat, a caliper housing slidably installed on the carrier and provided with a cylinder in which a piston is installed to advance and retreat by a braking hydraulic pressure, a hydraulic pressure supply device configured to supply the braking hydraulic pressure to the cylinder, a spindle member installed to penetrate through a rear portion of the cylinder and configured to rotate by receiving a rotational force of an actuator, a nut member configured to advance and retreat depending to the rotation of the spindle member to press and release the piston, and a power transmission device in which an input part is connected to an output shaft of the actuator and an output part is connected to the spindle member, and configured to transmit the rotational force of the actuator to the spindle member.

A device for actuating a brake shoe of a brake, in particular a disk brake, includes a pivotably mountable lever element, and a transmission element configured to be mounted in a longitudinally movable fashion is such that a pivot movement of the lever element is translated into a longitudinal movement of the transmission element wherein a hydraulic chamber configured to be filled with a hydraulic fluid is arranged between the brake shoe and the transmission element for the transmission of force between the brake shoe and the transmission element.

The present disclosure relates to a master cylinder and an electronic brake system having the same. The master cylinder includes a cylinder block having a bore of a multi-stage form in a longitudinal direction therein, a first master chamber and a second master chamber sequentially arranged in series in the bore, a first master piston provided to move in connection with an operation of a brake pedal and to pressurize the first master chamber, a second master piston provided to be displaceable by a displacement of the first master piston or a hydraulic pressure in the first master chamber and to pressurize the second master chamber, and a pedal simulator interposed between the first master piston and the second master piston to provide a reaction force to the brake pedal, wherein a cross-sectional area of the first master piston is provided to be relatively larger than a cross-sectional area of the second master piston.

An electric axle drive unit for a motor vehicle, having an electric motor with a stator that is fixedly received in a housing, and a rotor that is rotatably mounted relative to the stator and rotationally coupled or coupleable to a wheel hub. A brake device is operatively connected to the wheel hub. The brake device has a first brake component fixedly supported on the housing, a second brake component rotationally fixed to the wheel hub that is frictionally connectable to the first brake component, and an actuation unit that applies a braking force that interconnects the brake components. One of the brake components has a brake disc element rotationally fixed to a support part and is displaceably received in the axial direction of a rotational axis of the wheel hub relative to the support part.

A pushing force-actuated braking device includes an annular housing that houses a brake disc, a braking piston, plural braking elements, and a brake-releasing piston. When only the braking piston is under the action of a fluid, the braking piston applies an axial pushing force to the brake disc such that the brake disc is kept at a braking position jointly by the braking piston and the braking elements. When only the brake-releasing piston is under the action of a fluid, the brake-releasing piston applies an opposite pushing force to the brake disc to keep it at a brake-releasing position. Should the fluid acting on the braking piston fail, the force of the braking elements still enables the brake disc to produce a braking effect. The pushing force-actuated braking device has a modular design to facilitate assembly and disassembly. A rotary table using the braking device is also provided.
