Abstract
Abstract Automotive vehicle wheel and spring suspension of the type including a transversely extending leaf spring is adapted to effect adjustment of the vehicle sprung mass or chassis to a desired height or level attitude by manipulation of a spring connector assembly effective to raise and lower the outboard end of the spring independently of alteration of the wheel guidance apparatus of the suspension.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
In vehicle wheel spring suspension including a wheel support member and laterally extending control arm means swingably mounted by inboard pivot means thereof on the vehicle sprung mass and connected by outboard pivot means thereof to the wheel support member to constitute therewith an unsprung mass, height adjustable suspension spring means comprising a leaf spring secured to the vehicle sprung mass and extending for connection at its distal end to said unsprung mass, and a sprung mass height adjusting connector assembly interconnecting said distal end of the leaf spring with said unsprung mass independently of said outboard pivot means including means selectively adjustable in fine increments to vary the vertical relation between said distal end of the leaf spring and said unsprung mass.
Claim 2
Dependent Claim
123 words
In vehicle wheel spring suspension including a wheel support member and laterally extending control arm means swingably mounted by inboard pivot means thereof on the vehicle sprung mass and connected by outboard pivot means thereof to the wheel support member to constitute therewith an unsprung mass, height adjustable suspension spring means comprising a leaf spring secured to the vehicle sprung mass and extending for connection at its distal end to said unsprung mass, and a sprung mass height adjusting connector assembly interconnecting said distal end of the leaf spring with said unsprung mass independently of said outboard pivot means including means selectively adjustable in fine increments to vary the vertical relation between said distal end of the leaf spring and said unsprung mass.
Claim 3
Dependent Claim
131 words
In vehicle wheel spring suspension including a wheel support member and laterally extending control arm means swingably mounted by inboard pivot means thereof on the vehicle sprung mass and connected by outboard pivot means thereof to the wheel support member, a height adjustable suspension spring system comprising a transverse leaf spring secured at an inboard region thereof to the vehicle sprung mass and extending for connection at its outboard end to said wheel support member, and a sprung mass height adjusting connector assembly interconnecting said outboard end of the leaf spring with said wheel support member independently of said outboard pivot means, said connector assembly including bolt means selectively rotatable to carry said leaf spring outboard end in a path to vary the vertical relation thereof with said wheel support member.
Claim 4
Dependent Claim
131 words
In vehicle wheel spring suspension including a wheel support member and laterally extending control arm means swingably mounted by inboard pivot means thereof on the vehicle sprung mass and connected by outboard pivot means thereof to the wheel support member, a height adjustable suspension spring system comprising a transverse leaf spring secured at an inboard region thereof to the vehicle sprung mass and extending for connection at its outboard end to said wheel support member, and a sprung mass height adjusting connector assembly interconnecting said outboard end of the leaf spring with said wheel support member independently of said outboard pivot means, said connector assembly including bolt means selectively rotatable to carry said leaf spring outboard end in a path to vary the vertical relation thereof with said wheel support member.
Claim 5
Dependent Claim
155 words
Vehicle wheel spring suspension including a wheel support member and laterally extending control arm means swingably mounted by inboard pivot means thereof on the vehicle sprung mass and connected by outboard pivot means thereof to the wheel support member, a transverse leaf spring of polymeric material secured at an inboard region thereof to the vehicle sprung mass and extending for connection at its outboard end to said wheel support member, and sprung mass height adjusting means interconnecting said outboard end of the leaf spring with said wheel support member, said interconnecting means comprising a cam bolt rotatably mounted in said wheel support member and including a spring support portion oriented longitudinally of the vehicle sprung mass, the bottom surface of said outboard end of the leaf spring bearing upon said support portion whereby selective rotation of the cam bolt relative the wheel support member varies the vertical relation thereto of the leaf spring outboard end.
Claim 6
Dependent Claim
155 words
Vehicle wheel spring suspension including a wheel support member and laterally extending control arm means swingably mounted by inboard pivot means thereof on the vehicle sprung mass and connected by outboard pivot means thereof to the wheel support member, a transverse leaf spring of polymeric material secured at an inboard region thereof to the vehicle sprung mass and extending for connection at its outboard end to said wheel support member, and sprung mass height adjusting means interconnecting said outboard end of the leaf spring with said wheel support member, said interconnecting means comprising a cam bolt rotatably mounted in said wheel support member and including a spring support portion oriented longitudinally of the vehicle sprung mass, the bottom surface of said outboard end of the leaf spring bearing upon said support portion whereby selective rotation of the cam bolt relative the wheel support member varies the vertical relation thereto of the leaf spring outboard end.
