A disc brake (10) is described, comprising a brake disc (12) and two brake shoes (20), which are pressable against both sides of the brake disc (12) and which in relation to a peripheral force (C') generated upon application of the brake shoes (20) against the brake disc (12) are supported against a vehicle-fixed carrier (14). The disc brake (10) moreover comprises at least one device (34) for measuring and/or converting the peripheral force (C'), which device is disposed in a force transmission...

A disk brake including friction pads disposed opposite to a brake disk, a bracket provided with support portions for movably supporting the friction pads so as to permit sliding along the axial direction of the brake disk, and retainers each interposed between the friction pad and the support portions, to restrain at least movements of the retainers relative to the support portions of the bracket. Of a pad holding force with which the retainer holds the friction pad, and a retainer supporting fo...

The invention relates to a disk brake provided with a brake caliper comprising a brake disk, a sliding member which can be displaced in a vertical manner in relation to the surface of the brake disk in the brake caliper and can be engaged against the brake disk, and a clamping device comprising a rotary lever and a rotational body. In one embodiment of the invention, the rotary lever comprises a domed-shaped control surface whereon the rotational body is arranged in a rotational contact position...

An actuator arrangement for a disc brake for moving first and second friction members into engagement with a rotor and effect a brake application. The actuator arrangement includes first and second levers that are pivotally connected to an anchor located in a plane that is perpendicular to first and second rails on which the first and second friction member are retained, a third lever that is connected to the first lever and a yoke to receive a second end of the second lever and align a first ra...

A disc brake which is particularly designed for arcuate travel of less than 360 degrees has sector shaped segments, i.e. segments which are not complete circles and which are interleaved into a disc pack of multiple layers, wherein some layers of the disc pack each consist of a single disc segment which is less than a complete circle. Some segments are rotatable about an axis and others are stationary and have friction brake material carried on them at a position remote from the axis of rotation...

A brake actuator including a chamber in which is provided a movable pressure responsive element which divides the chamber into first and second compartments, the brake actuator also including a valve assembly with an inlet which is connected to a source of pressurised fluid, an outlet which is connected to a volume within the brake actuator not including the second compartment, and an exhaust port through which fluid from the volume may be released, wherein the exhaust port of the valve assembly...

A brake disc capable of sufficiently absorbing thermal stress associated with thermal expansion and deformation of the braking section. The brake disc includes a mounting section for attachment to a wheel, a braking section located at the outside circumference of the mounting section for brake pads to be brought into sliding contact therewith, and a connecting arm section for connecting each of the plurality of mounting portions of the mounting section and the braking section. Connecting arms in...

The present application discloses a brake actuator for applying tension to a brake cable. The actuator includes: a mounting bracket; a brake actuator lever mounted for pivotal movement relative to the mounting bracket in brake applying and brake releasing directions; and a cam-and-drum member mounted for rotation relative to relative to the brake actuator lever. The cam-and-drum member is formed as one integral part including a protruding drum portion and a cam portion integral with the drum por...

A rope brake for an elevator installation for braking a rope coupled to a car is provided, which has a stop that is immovable in the longitudinal direction of the rope and at least one brake shoe. The rope is led between the stop and the brake shoe, and the brake shoe is adapted to be moved back and forth between a braking position, pressing the rope against the stop, and a release position, releasing the rope. A drive coupled to the brake shoe is provided for releasing the rope. The drive is fo...

A brake system for a mobile work tool, such as for a logging machine or a combined dredger-loader, is disclosed. The mobile work tool is provided with two non-muscular brake valves for brake actuation which may be operated by the driver in accordance with the orientation in the driver's cab--for instance during road travel and when the driver's direction of view is to the rear. In accordance with the invention, a tank port of a non-muscular brake valve is connected with the brake port of the sec...
