Abstract
Abstract A linkage used with vehicle wheels individually mounted on vertically adjustable struts to prevent toe-in or angular movement of the wheels as a result of vertical extension and retraction of the strut. This is accomplished by the use of links which permit vertical movement of the wheels relative to the vehicle frame and having steering means connecting the wheels to the frame but fixed against vertical movement.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
161 words
In a multiwheel vehicle of the kind in which each wheel is suspended from the vehicle frame by an extensible oleo-pneumatic strut and wherein some of the wheels are steerable and some of the wheels are not steerable, linkage means for maintaining a preselected toe-in of both the steerable and nonsteerable wheels to minimize tire scuffing when the struts change length, said linkage means including scissors links and drag linkage at each wheel, said scissors links being pin joint connected together at one end with the other ends of the scissor linkage being pin joint connected to the part of the strut connected to the wheel and to the part of the strut connected to the frame respectively, and said drag linkage being swivel joint connected to the part of the strut connected to the frame, whereby both the steerable and nonsteerable wheels can move up and down on strut construction and extension without moving arcuately with respect to the frame.
