Abstract
A rubber bump stop composed of at least two components (“Durobumps”) and used as a suspension product is disclosed that greatly extends suspension life of the vehicle and increases vehicle stability in rough terrain or harsh driving conditions. Preferably, the rubber bump stop has at least four components and include cast in place metal hardware for use in fastening to the vehicle.
Claims16
A bump stop for use in a vehicle suspension system comprising:
- an integrated composite composed of at least three separate layered components comprising:
- a majority portion component making up 60 to 85 volume percent of the composite and having a durometer between 60 and 80;
- a first minority portion making up a maximum of about 20 volume percent of the composite and having a durometer between 20 and 60;
- and
- a flared base portion having a durometer greater than or equal to 80;
- and
- a hole through the bump stop having a diameter between 8 mm and 17 mm.
4 more elements
A method of forming a bump stop, the method comprising:
- forming a plurality of layered elastomeric mixtures into a desired shape, wherein the plurality of elastomeric mixtures comprises a first volume having a durometer between 60 and 80, a second volume having a durometer between 20 and 60 and a third volume having a durometer greater than or equal to 80;
- wherein the second volume is configured to reside between the first volume and the third volume.
