    • The present invention provides a brake actuator assembly including a housing having a generally radial annular flange portion and a cover having a generally radial annular flange portion generally co-axially aligned with the generally radial annular flange portion of the housing. A cup-shaped flexible diaphragm having an outer radial annular rim portion is disposed between the generally radial annular flange portions of the housing and the cover. A retaining element generally surrounds and compresses the generally radial annular flange portions of the housing and the cover against the rim portion of the flexible diaphragm. The rim portion of the diaphragm includes a wedge-shaped edge portion and co-axially aligned flats on opposite sides of the rim portion adjacent to the wedge-shaped edge portion aligning the flange portions of the housing and the cover. In another embodiment, a flexible brake diaphragm includes a cup-shaped flexible diaphragm having an outer radial annular rim portion. The rim portion of the diaphragm includes a wedge-shaped edge portion and co-axially aligned flats on opposite sides of the rim portion adjacent to the wedge-shaped edge portion.

    • Brake actuators are provided with self-centering diaphragms. In one embodiment, the diaphragm is provided with a centering bead radially outwardly of a sealing bead. The centering bead ensures the diaphragm is properly centered prior to the brake actuator housings being secured together. In a second embodiment, the self-centering structure includes structure fit into mating structure in one of the brake actuator housings to ensure the diaphragm is properly centered. The self-centering structure ensures the brake actuator diaphragms are properly centered before connection of the two brake actuator housings. This invention is particularly useful in the type of brake actuator housings having deformed housing portions.

    • An improved diaphragm-type pneumatic brake actuator wherein the diaphragm is releasably secured to the piston as the diaphragm is inverted during actuation of the braking system of a vehicle thereby reducing wear of the flexible diaphragm and improving the performance of the brake actuator. In the disclosed embodiment, a rib or lip is formed on the surface of the diaphragm which receives the periphery of the piston as the diaphragm is inverted forming a mechanical interlock between the diaphragm and the piston thereby preventing spacing of the contact surface of the piston and the central portion of the diaphragm and frictional wear between the peripheral edge of the piston and the diaphragm. In the preferred embodiment, the piston includes an arcuate rim which extends away from the central portion of the diaphragm when the diaphragm is located in its extended cup-shaped position prior to actuation of the vehicle braking system and the diaphragm then conforms to the arcuate rim as the diaphragm is inverted and the diaphragm rib snaps over the piston rim as the diaphragm is inverted to actuate the vehicle braking system. The diaphragm rib may be molded on the surface of the diaphragm when the diaphragm is molded without any substantial increase in cost.
    • 一种改进的隔膜式气动制动器致动器,其中当在车辆的制动系统的致动期间隔膜被倒置时,隔膜可释放地固定到活塞,从而减少柔性隔膜的磨损并改善制动致动器的性能。 在所公开的实施例中,在隔膜的表面上形成肋或唇缘,当隔膜反转时,隔膜的表面接收活塞的周边,从而在隔膜和活塞之间形成机械互锁,从而防止活塞和接触表面的间隔 隔膜的中心部分和活塞周边边缘与隔膜之间的摩擦磨损。 在优选实施例中,活塞包括弓形轮辋,当隔膜在致动车辆制动系统之前位于其延伸的杯形位置时,其延伸远离隔膜的中心部分,并且隔膜然后符合弓形轮辋 当隔膜反转并且当隔膜反转以使致动车辆制动系统时,隔膜肋卡在活塞边缘上。 当膜片模制时,隔膜肋可以模制在隔膜的表面上,而不会显着增加成本。

    • An improved brake actuator is fully sealed against ingress of liquid or other contaminants. Separate breather tubes selectively communicate each of the pressure ports to the non-pressurized sides of the service and spring chambers. The separate breather tubes provide clean air into the non-pressurized chambers. Relief valves are positioned in each of the breather tubes. The pressurized ports may be reconfigured into two configurations such that the source of pressurized air may be connected to either of two orientations. In addition, a seal closely receives the push rod such that the non-pressurized chamber of the service side is fully sealed against ingress of liquids.

    • A braking system for the tractor unit of a tractor trailer vehicle in which the ratio of the pressure applied to the front brakes to the pressure applied to the rear brakes changes automatically when a trailer is connected to or disconnected from the tractor. The brake system includes two dual mode relay valves and feedback conduits which convey feedback pressures between the front and rear dual mode valves and between a trailer brake service conduit and the front valve. The brake system includes brake pressure proportioning apparatus which is operative to reduce brake pressures on the rear tractor brakes, during normal brake applications, when the tractor is operated bobtail but which can be overriden by a vehicle operator if conditions warrant. The pressure feedback and system hysterresis cooperate to produce balanced braking and the proper sequence of brake application under a variety of vehicle operating conditions.
