671,236. Vehicle steering. WEBER, J. L. W. Jan. 11, 1950 [Jan. 13, 1949], No. 749/50. Class 79(v) A vehicle steering mechanism comprises a split track rod, the two inner ends thereof being pivoted to an intermediate member which is movably connected to a steering member, the intermediate member being guided in a fixed path relatively to the chassis so that the paths followed by the inner ends of the track rods are non- circular. The latter paths are curves whose dimension measured transversely of the vehicle is greater than that measured longitudinally. As shown in Figs. 7 and 7a, the rearwardly directed diverging steering arms 5, 6 are connected by track rod portions 17, 18 to a T-shaped intermediate member 31. Member 31 is pivoted at 30 to a steering member 21 rotatable for steering about a fixed point 22, and is guided by roller 32 in guides 33 extending longitudinally of the vehicle. With such a mounting the operative end of the T-shaped member describes a non-circular arc and enables a greater steering lock to be obtained. Figs. 8 and 8a show the arrangement applied to forwardly directed converging steering arms 15, 16 with crossed track rod portions 24, 25. The intermediate member 31 is pivoted as before to a steering member 21 and is guided by roller 32 in a longitudinal guide 33. In a further modification, Fig. 11, the crossed track rod portions 24, 25 are connected to an intermediate member 35 which is slidable on the pivoted steering member 21, and which is constrained by a link 49 pivoted thereto and to a fixed point 50, whereby the member 35 describes a non-circular arcuate path. Alternatively, the member 35 may be slidably mouted on the pivoted steering member 21 and may be guided along the desired non-circular arcuate path by a pair of suitably curved guide rails which engage a projection roller on the member 35.
