786,759. Spring suspensions; adjusting body height. MOTOR RESEARCH CORPORATION. Feb. 28. 1955 [March 1, 1954], No. 5950/55. Class 108(2) [Also in Group XXXVII] A suspension mechanism for a motor vehicle having a frame or body structure and front and rear wheels, comprises main yieldable suspension means for supporting the structure on the wheels, compensating means for supplementing or modifying the suspension means thereby to levelize the vehicle structure and compensate for varying static load conditions, control means for controlling the operation of the compensating means and means for actuating the control means including an actuating member adapted to be operated by the main yieldable suspension means consequent upon a static load change at or adjacent one end of the vehicle. As shown, front wheels 24 are carried by upper and lower links 26 and 29 and driven rear wheels 26 are carried by torque arms 37 and lever arms 48. The latter are rigidly connected to the rear ends of main torsion springs 41, the other ends of which are connected through links 45 to one arm 26b of the lower links 29. An auxiliary torsion spring 52 at each side of the vehicle is rigidly connected at its rear end to the arm 48 and at its forward end is rigidly secured to the lower end of a lever through which it extends for rotation in a bearing bracket 56. The upper end of the lever is pivotally connected to an adjustable link 57 which is pivoted to a sector gear 60 mounted on a frame member 21 and adapted to be driven by a reversible electric motor 67 thereby to vary the torsional stressing of the torsion spring 52. The spring 52 at the other side of the vehicle is similarly connected to the sector gear through a link 69. The motor 67 is controlled by a compensator switch mechanism 72 (see Group XXXVII) which is connected through a lever arm (not shown), adjustable link 108 and another lever arm (not shown), to one of the torsion springs 41 at or near the neutral point thereof. Reference has been directed by the Comptroller to Specifications 736,205 and 756,026.
