Claims30
A rubber tired vehicle suspension which comprises load bearing spring means comprising at least one resilient rod spring composed of an elongated body of elastomeric material having opposed elongated longitudinal load bearing surfaces;
- and mounting means for attachment between the body and running gear of a vehicle, said mounting means carrying said rod spring in a position such that load bearing compressive forces are transmitted to said load bearing surfaces transversely of the rod spring longitudinal axis without producing rotation of said rod spring about its longitudinal axis with respect to said mounting means, while simultaneously therewith permitting the unloaded rod spring surfaces to bulge freely.
A rubber tired vehicle suspension which comprises at least axle means;
- at least one pair of rubber tired wheels journaled on said axle means;
- a pair of suspension means secured to said axle means and positioned one adjacent the wheels;
- each said suspension means comprising a first support securing said suspension means to said axle means, a second support for securing said suspension means to the body of a vehicle, load bearing spring means comprising at least one resilient rod spring composed of an elongated body of elastomeric material having opposed elongated longitudinal load bearing surfaces and carried between the supports in a position such that load bearing compressive forces are transmitted to said load bearing surfaces transversely of the rod spring longitudinal axis without producing rotation of said rod spring about its longitudinal axis with respect to the supports, while simultaneously therewith permitting the unloaded rod spring surfaces to bulge freely.
