Abstract
An automotive suspension assembly providing a jounce stop arrangement. The elastic bumper is placed into a flexible cup. The flexible cup connects to the surface of the cylinder of a strut assembly or other assembly. Upon application of a force upon the elastic bumper, the elastic bumper collapses into the flexible cup. The flexible cup also expands in reaction to the force upon the elastic bumper. The assembly provides dual system of absorbing the energy from an impact in the combination of collapsing and expanding of the elastic bumper and flexible cup.
Claims17
A jounce bumper assembly for a wheel suspension system of a vehicle including a frame member and a strut member displaceable relative to said frame member along a line of travel, comprising:
- a first flexible member disposed between said frame and said strut members along said line of travel, having a recess and an annular portion surrounding said recess therein aligned with said line of travel;
- and
- a second compressible member disposed between said strut and said first flexible member, having a portion thereof received within and seated in said recess,
- wherein upon a force applied along said line of travel, said second compressible member collapses into said recess causing said annular portion to expand radially.
A jounce bumper for a wheel suspension system of a vehicle including a first member and a second member displaceable relative to said first member along a line of travel, comprising:
- a first flexible member disposed between said first and second member along said line of travel having a recess and an annular portion surrounding said recess therein aligned with said line of travel;
- and
- a second compressible member disposed between said first member and said first flexible member, having a portion thereof received within and seated in said recess,
- wherein upon a force applied along said line of travel between, said second compressible member collapses into said recess causing said annular portion to expand radially.
An energy absorption device including a first member and a second member displaceable along a line of travel comprising:
- a flexible member disposed between said first and second member along said line of travel having a recess portion and an annular portion surrounding said recess portion;
- and
- a compressible member disposed along said line of travel and having a portion thereof received in said recess,
- wherein upon a force applied along said line of travel, said second compressible member collapses into said recess causing said annular portion to expand radially.
