20150240893 | COMBINED VEHICLE BRAKE - A combined vehicle brake having a hydraulically actuable driving brake and an electromechanically actuable parking brake device. In a brake housing, a hydraulic operating pressure space is bounded by a brake piston chargeable with hydraulic pressure medium to carry out normal braking. The brake piston is actuable along a longitudinal axis of the piston, and the parking brake device acts on the brake piston by a gearing converting the rotational movement of an electromechanical actuator into a translation movement and bringing about an actuation of the brake piston in order to carry out parking brake operations and keeping the brake piston in the actuated position. The gearing has a threaded spindle and a threaded nut which are in contact with each other via a plurality of rolling bodies. The frictional moment transmitted by the further axial bearing is higher than the returning torque of the threaded spindle. | 2015-08-27 |
20150240894 | Brake - A brake for machine and method of using the brake is disclosed. The brake may comprise first and second brake linings configured to be frictionally engageable with a rail, a first biasing member configured to urge the first brake lining to engage the rail, and a first actuator configured to move the first brake lining to disengage the rail when the first actuator is energized. The brake may be configured to be mounted on a machine, floor or the like. | 2015-08-27 |
