Patent number: 11814023Abstract: 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.Type: GrantFiled: August 31, 2020Date of Patent: November 14, 2023Assignee: Bendix Commercial Vehicle Systems LLCInventor: Will E Roberts

Patent number: 11745716Abstract: An interface between an adapter push rod and a parking brake diaphragm seal includes an axial projection at one end of the push rod, a thread extending axially between a free end of the projection and a remainder of the push rod, and a washer having an approximately conical wall extending radially inwardly from an outer circumference of the washer towards a central mounting connection having a radial flange. A nut is threaded over the free end of the projection, and an opening in a hardened element is aligned axially with the projection to receive the projection. A circumferential groove defined in a side of the radial flange forms a boundary between the approximately conical wall and a remainder of the washer, and a portion of the diaphragm seal is pressed by the nut and the hardened element into the circumferential groove to produce a sealing bead.Type: GrantFiled: December 22, 2020Date of Patent: September 5, 2023Assignee: Bendix Commercial Vehicle Systems LLCInventor: Will E.

Patent number: 9816574Abstract: A system and method are provided for mounting, removing and retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles, in a manner which does not require the use of separate brake pad retaining devices while providing positive retention of the brake pad. A preferred embodiment includes a brake caliper mount having brake pad abutment surfaces having radially-oriented and lateral grooves which permit a brake pad with corresponding projections on is lateral sides to be inserted through an opening of the brake caliper into the radially-oriented grooves until the backing plate projections are aligned with the lateral groove, and advancing the brake actuator behind the brake pad to place the brake pad in an operating position in which the actuator prevents the brake pad from realigning with the radially-oriented grooves until the actuator is retracted to permit brake pad extraction.Type: GrantFiled: January 10, 2017Date of Patent: November 14, 2017Assignee: Bendix Spicer Foundation Brake LLCInventors: Ronald S. Plantan, Harish Radhakrishnan, Dennis A. Wolf, Richard L. Lantz, Will E. Roberts, Steven C. Bell
