Abstract
Abstract A vehicle suspension system is disclosed which has radius arms for connecting an axle assembly to a frame to accomodate the necessary relative movement therebetween. An improved connection is provided for rigidly securing the radius arms to the axle assembly. The connection consists of a cast wedge bracket adapted to be secured between an axle tube and wheel supporting yoke and mating wedge portions formed on the radius arm and associate clamp.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
177 words
A vehicle suspension system for use between a frame and an axle assembly disposed below the frame, the axle assembly comprising: an axle shaft having an outer end, a yoke member aligned with and spaced from said axle shaft outer end, bracket means disposed between said axle shaft outer end and said yoke member, said bracket means having a main body portion and integral outwardly extending inner and outer mounting portions, said inner mounting portion secured to said axle outer end and said outer mounting portion secured to said yoke member, said main body portion defining first and second opposed wedge elements having walls which converge at their free ends, a radius arm having one end pivotally attached to the frame and a bifurcated end defining converging walls for engaging said converging walls of said first wedge element, a clamp having converging walls for engaging said converging walls of said second wedge element, and fastening means for securing said clamp to said bifurcated end of said radius arm to rigidly secure said mating walls in mating engagement.
Claim 2
Dependent Claim
177 words
A vehicle suspension system for use between a frame and an axle assembly disposed below the frame, the axle assembly comprising: an axle shaft having an outer end, a yoke member aligned with and spaced from said axle shaft outer end, bracket means disposed between said axle shaft outer end and said yoke member, said bracket means having a main body portion and integral outwardly extending inner and outer mounting portions, said inner mounting portion secured to said axle outer end and said outer mounting portion secured to said yoke member, said main body portion defining first and second opposed wedge elements having walls which converge at their free ends, a radius arm having one end pivotally attached to the frame and a bifurcated end defining converging walls for engaging said converging walls of said first wedge element, a clamp having converging walls for engaging said converging walls of said second wedge element, and fastening means for securing said clamp to said bifurcated end of said radius arm to rigidly secure said mating walls in mating engagement.
