Abstract
Abstract Tension spring assemblies are suspended between the steerable wheel assemblies of a heavy vehicle and the frame of the vehicle for the purpose of urging the lower portions of the steerable wheels inwardly beneath the vehicle. Each spring assembly includes one or more coil springs and a clamp connected to the lower enlargement of an I-shaped frame member of the vehicle frame. The clamp is connectable to the I-shaped frame member without cutting or otherwise altering the configuration of the frame member.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
256 words
In a steerable vehicle suspension system of the type including at least one rotatable wheel mounted on a spindle and pivotal about a generally upright axis, the vehicle including a frame with a frame member of approximately I-shaped cross sectional shape and including a vertical web and an enlarged lower portion extending toward the wheel, the combination therewith of a tension spring assembly connected at one of its ends to the wheel spindle and at its other end to said frame member and including a clamp comprising a base plate positionable beneath the frame member and of a width wider than the frame member and a pair of L-shaped clamp elements each including an upwardly extending leg braced at its lower end against said base plate and extending upwardly from said base plate and a lateral leg projecting from the upper end of said upwardly extending leg and projecting laterally inwardly over the enlarged lower portion of said frame member and toward the vertical web of said frame member, said base plate defining openings therethrough at opposite sides thereof spaced apart a distance further than the width of the enlarged lower portion of said frame member, and the lateral leg of each of said clamp elements defining openings therethrough, and bolts extending through the openings in said base plate and the openings of the lateral leg of said clamp elements for drawing the lateral leg of said clamp elements against the enlarged lower portion of said frame member and tightening said clamp on said frame member.
