摘要： A pneumatic brake actuator has a housing and a divider that divides the housing into a spring chamber containing a spring and a pressure chamber. The divider has an opening that receives an end of an actuator tube. A bearing that is positioned within the opening in the divider is joined to both the divider and the actuator tube. A caging bolt has a first end positioned within the actuator tube and extends from the first end through openings in the hearing and housing to a second end positioned outside of the housing. The connection between the bearing, divider and actuator tube contains the spring within the housing in the event that the housing and/or divider fails. The divider can be a piston or a diaphragm and pressure plate. The bearing can be joined to either of the divider and actuator tube with threads and/or by welding.

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 long-stroke fail-safe spring brake assembly for heavy duty vehicles comprises aligned first and second cups secured adjacent one another to form a housing for a compressed power spring which biases a spring piston, a hollow tubular push rod having one end open and sealingly secured, preferably by press fitting, to the spring piston and the other end closed and extending sealingly through the second cup for reciprocal control of a brake actuator by the power spring, an annular-shaped flexible diaphragm having an outer periphery radially-sealingly secured adjacent between the cups and an inner periphery sealingly secured adjacent the outer periphery of the spring piston, the intermediate portion of the diaphragm being disposed radially-outwardly of the spring piston. The spring piston is disposed to compress the compressed spring still further toward the first cup under the influence of a compressed fluid medium, the push rod, and the spring piston being sealingly secured to each other. The hollow interior of the push rod houses an elongated caging member having a distal portion confined therein which prevents separation of the compressed spring from the first cup in the event the latter is separated from the second cup. The push rod reciprocates sealingly through the second cup by a centerseal bearing comprising opposed interlocked plastic components sealed to each other by fused contact.

摘要： This apparatus is a fastener assembly for retaining a spring, such as used in the brake actuators of heavy-duty trucks, in a compressed state, including a fully-compressed state, the assembly being variably adjustable to accommodate variations in actual spring dimensions and tolerances. The compressed spring is held between first and second members by a fastener assembly comprising a washer and a clip, the washer having an opening therein for receiving the clip. The clip has an enlarged head with sloping shoulders which ride on the periphery of the opening in the washer, and a shank which engages the second member and maintains the clip stationary with respect thereto. The shape of the periphery of the opening in the washer and the slope of the shoulders on the head of the clip are designed such that when the washer or clip is rotated with respect to the other from a rest position the spacing between the first and second members is progressively reduced, whereby the fastener assembly is selectively adjusted to accommodate the compressed spring in its minimum selected dimension.

摘要： A method and apparatus for positioning components of a brake system, which includes a push rod, a ball end coupled to the push rod, and a force transfer member placed between the push rod and the ball end. The force transfer member has both a flowable property and a solidifying property, whereby the force transfer member is flowable when being placed between the push rod and ball end and, after a passage of time, the force transfer member solidifies.
