摘要： A pneumatic brake actuator has a spring brake actuator with spring and spring brake pressure chambers, and a service brake actuator with service brake pressure and pushrod chambers. A control valve has a seal that is moveable between an open position and a closed position for regulating fluid flow between the spring chamber and service brake pressure chamber. A first surface of the seal is in fluid communication with the service brake pressure chamber and a second surface of the seal is in fluid communication with a valve chamber that is not in fluid communication with the service brake pressure chamber or spring chamber. The seal moves between its open and closed positions based on a pressure in the service brake pressure chamber. Movement of the seal is not dependent on the rate of flow of fluid between the spring chamber and the service brake pressure chamber.

摘要： A disc brake apparatus structured such that, on receiving a pressing force from an operating spring, a piston arranged within a cylinder formed in a caliper body presses a piston side pad. The disc brake apparatus includes a support part formed in a part of the caliper body, a reaction force receiver provided on and projected from the lateral side of the piston and opposed to the support part, and cam parts interposed between the support part and the reaction force receiver and, on receiving a rotation force, capable of spreading the distance between the support part and the reaction force receiver to thereby release the pressing force.

摘要： A sealing assembly for installation on a port of a spring brake actuator includes a plug, a one-way valve and a cap. The plug receives the one-way valve for providing one-way air flow through the orifices and maintaining about two psi in the spring brake chamber at zero stroke. An elastomeric piece is affixed to a first set of segments of the plug for sealing against an inner surface of the port. The cap has arms sized to extend around a third set of segments of the plug and snap onto the plug. A fourth set of segments of the plug elastically deform so the sealing assembly can be installed and removed from the port easily.

摘要： A disc brake device for a vehicle, the disc brake device is equipped with: a piston slidably fitted into a cylinder hole provided in one arm section of a brake caliper, and capable of pressing against one friction pad; a shim plate mounted on a back plate of the one friction pad and interposed between the back plate and the piston; and a pressing device that applies pressing force to the piston while causing rotational force to act on the piston. Multiple protrusions protruding toward the piston are provided, with intervals between the protrusions, on the back plate of the friction pad facing the piston with the shim plate therebetween, and multiple engaging holes, into which the multiple protrusions are fitted, are provided on the shim plate so as to prevent the shim plate from rotating together with the piston due to the rotational force.

摘要： In a brake actuator including a plurality of actuator housing portions, a diaphragm seal, partially delimiting a parking brake de-actuation chamber, is retained between adjacent actuator housing portions, and an elastic element disposed between the diaphragm seal and one of the housing portions opposes expansion of the parking brake de-actuation chamber. A push rod extends into and out of a service brake actuation chamber upon respective release of fluid pressure from the parking brake de-actuation chamber and supply of fluid pressure to the parking brake de-actuation chamber. In order to constrain a central portion of the diaphragm seal for movement together with both the push rod and a piston, a clamping arrangement is used to axially clamp the central diaphragm seal portion between an end of the push rod and a surface of the piston.

摘要： The utility model relates to a pneumatic brake release apparatus used on an elevator traction machine, which includes an air cabin, an air storage tank, air delivery pipes, air films, a push rod and air control apparatuses, wherein the air films are arranged at two sides in the air cabin, one end of the push rod is connected to the air films, the other end of the push rod penetrates through the outer wall of the air cabin and is connected with the upper end of a locking arm, an intermediate air cabin of the air cabin is provided with an intermediate air inlet end and an intermediate air outlet end, a film-anterior air cabin of the air cabin is provided with a film-anterior air inlet end, the intermediate air inlet end and the film-anterior air inlet end of the air cabin are respectively connected with the air storage tank by virtue of the air delivery pipes, and the intermediate air outlet end is directly communicated with the atmosphere. By means of the technical solution, the air films in the air cabin are pushed by using compressed air to drive the push rod to transfer a thrust force, so that the locking arms are unfolded, and the locking brake and the brake release are implemented in a pneumatic way. Therefore, the problems in the prior art that a great amount of electric energy is consumed and the noise is difficult to eliminate can be solved, no noise is generated during operation, the safety is high, the structure is simple, and the manufacturing cost is greatly reduced.
