Patent number: 8931768Abstract: A mount assembly for a suspension damper is provided which includes a piston rod extending about an axis and a mount housing. A jounce bumper is axially positioned about the piston rod and has an end surface and a radially outer surface. The jounce bumper is formed of a first deformable material selectable for absorbing energy from an axial force applicable through the piston rod. A jounce bumper cup formed of a second deformable material selectable for absorbing additional energy fits onto the end surface of the jounce bumper. The jounce bumper cup has a wall portion extending sufficiently around the radially outer surface of the jounce bumper to retain it in position and a load mount portion extending to the mount housing and being configured to absorb the additional energy.Type: GrantFiled: June 12, 2012Date of Patent: January 13, 2015Assignee: GM Global Technology Operations LLCInventors: Robert L. Geisler, Ravindra P. Patil, Joseph A. Schudt, Daryl R. Poirier
