摘要： A peripheral sealed interlock for a dual diaphragm tandem vacuum booster with front and rear housings is provided. An outer radial peripheral end of a divider of the inventive interlock is greatly simplified and in the preferred embodiment a bead of a secondary diaphragm is allowed to seal on a rear housing member as well as with the periphery of the divider. The interlock provides a simplified design allowing independent compression of primary and secondary diaphragm beads while at the same time providing an interlock which require lower compression for assembly and sealing.

摘要： A power booster assembly, has a dual-durometer reaction disc instead of the disc having a single durometer value throughout. The disc has an outer annular portion of a higher durometer value than the durometer value of the disc inner center portion. The higher durometer value is preferably on the order of 80 durometer and the lower durometer value is preferably on the order of 45 durometer. The outer annular portion transmit part of the reaction force to the booster power wall, and the inner center portion transmit the remainder of the reaction force to the reaction piston and thence to the booster input member. The disc may be made as a unitary part or may be made in two parts with the inner center portion being later inserted into and mechanically interlocked with the outer center portion.

摘要： A push rod is connected in pivotal retained relation to a polymeric member such as a power booster air valve polymeric insert having a stiffness less than that of an air valve. In a preferred embodiment, the insert is fitted on the spherical ball end of the push rod, and the insert with the push rod is then inserted into a recess in the member. The insert has a plurality of arms extending from the insert base end at a slight angle outwardly relative to the insert axis. The insert also has an attached metallic end on its base end to better distribute the force input from the push rod to the air valve. The arms and the member recess are provided with various cam surfaces which force the arms inwardly in cantilever fashion during the insertion movement, and the arms have surfaces on their outer ends which fit within an annular groove in the cylindrical side wall of the member recess, locking the insert to the rod spherical ball end and also within the member recess.

摘要： A brake booster is provided having a power piston slidably mounted in a housing. In a preferred embodiment the piston has a generally radial flange. Encircling the power piston is a flexible diaphragm having along its inner periphery a bead encircling the power piston and a sheet-like section radially extending from the bead. A retaining ring has a first section extending radially outward, a second section generally parallel with the piston and a third section with teeth projecting radially inwardly. Pushing the retainer towards the flange causes the bead to be radially compressed and the third section of the retainer to be deformed. The wedging causes the retainer to be retained in place sealably connecting the diaphragm with the power piston.

摘要： A disc brake assembly has a hub that is rotatable about an axis and at least a pair of discs supported on the hub for relative axial movement along the axis of the hub with the discs having opposite sides presenting braking surfaces. A non-rotatable support structure supports a plurality of friction elements for relative axial movement into and out of frictional braking engagement with the braking surfaces of the discs. An electric actuator is mounted on the support structure adjacent at least one of the friction elements and is operative when actuated to move the friction elements into frictional braking engagement with the braking surfaces of the discs.

摘要： A guide rod extends longitudinally through the power piston of a vacuum power booster providing lateral support thereto and tying the master cylinder housing to a bracket on the rear of the power booster housing. A guide rod provides a means of positively laterally supporting the power piston, control valve and push rods of the power booster thereby providing the ability to reduce the relative supportive strength of the housing, housing divider and piston bearings.

摘要： An integrated master cylinder and vacuum power booster provides a brake apply system wherein the master cylinder and power booster are structurally and functionally combined together to provide a uniquely packaged system. The integral system includes a master cylinder housing having a tubular extension that carries the power booster housing with at least two operating chambers. A power piston is movable by variable pressure levels between the two chambers. The power piston cooperates with a translating element carried within the tubular extension to communicate sliding movement of the power piston to the master cylinder piston.
