Patent number: 9097304Abstract: A system and method are provided for retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles, and for installing and removing brake pads, without the need to employ brake pad retaining devices which radially over-top the brake pads. A preferred embodiment includes a retaining element, preferably a spring steel clip, having protrusions which face in opposite directions to engage corresponding slots in a brake pad lateral edge and in a brake pad carrier brake pad-facing surface. When installed in a radially-inward direction, the brake pad carrier side protrusion engages the brake pad carrier slot, and cooperates with the brake pad lateral side protrusion to resist brake pad movement in the radially-outward direction. The brake pad carrier side protrusion may be manually pressed toward the brake pad to disengage the protrusion from the carrier slot to permit withdrawal of the brake paid from the carrier.Type: GrantFiled: November 9, 2012Date of Patent: August 4, 2015Assignee: Bendix Spicer Foundation Brake, LLCInventors: Ronald S. Plantan, Lonnie F. Cool, Harish Radhakrishnan

Patent number: 9091319Abstract: The present invention provides a hydraulic shock absorber. A solid main piston is designed to slide in a damping cylinder parallel to the movement generated when the shock absorber is subjected to a compression or a rebound stroke, the main piston dividing the damping cylinder into a first damping chamber containing the piston rod and a second damping chamber which does not contain the piston rod. A pressurization reservoir is pressurized by a force acting on a moving piston. The pressurization reservoir is arranged outside the damping cylinder and oriented at an angle relative to the damping cylinder. Two separate, adjustable valves generate a damping force acting in opposition to the stroke movement by restricting a damping medium flow between the damping chambers. A fourth defined chamber is hydraulically connected via separate flow paths to both the first and the second damping chamber and the pressurization reservoir.Type: GrantFiled: February 4, 2008Date of Patent: July 28, 2015Assignee: Ohlins Racing ABInventors: Atsushi Ishii, Alexandra Jarlmark
