Abstract: 17,227. Fulton, C. W. July 31. Motor road vehicles. - The vehicle body is prevented from tilting or canting relatively to the axles in either a tranverse or longitudinal direction while allowing vertical play to the springs. In the arrangement shown in Fig. 1, for preventing lateral tilting, four parallel rods A, arranged in pairs above and below the axle D, are connected at their inner ends to links B pivoted to a bracket C carried by the axle, and at their outer ends are connected to brackets E depending from the vehicle body. The rods A may be connected to the brackets E by rigid pivots, or double-acting. spring connexions may be provided, as shown, to allow slight momentary tilting. This arrangement may be applied to both front and rear axles or to either, or the bracket C may be carried on a cross-member supported by longitudinal members mounted on the axles. In another arrangement, shown in plan in Fig. 4, two pairs of transverse parallel rods A are employed, one pair on each side of the axle B. The upper and lower rods of each pair are connected at one. end to the brackets E, E<1> on the vehicle, and at the other ends to brackets C on the axle. Singleacting springs F are arranged between the rods and the brackets C. The brackets C are preferably arranged at opposite ends of the axle, but may be arranged at intermediate points. A similar arrangement employing only two parallel rods may be provided, double-acting springs being used. An arrangement is described in the Specification. in which four rods, two above and two below the axle, are pivoted at their outer ends to brackets depending from the vehicle body and at their inner ends to a central bracket on the axle. This arrangement may be modified by placing two brackets, one at each end of the axle, and a central bracket carried by the vehicle body. In the last two arrangements, the rigid pivots may be replaced by single-acting spring connexions. A similar arrangement is also described in the Specification, in which three rods only are used, two on one side of the central bracket and one on the other. Any of the above arrangements may be employed for preventing longitudinal tilting. Fig. 7 shows a suitable arrangement for this purpose. Two pairs of parallel rods A on each side of the vehicles are connected at their outer ends by single-acting springs F to brackets E depending from the vehicle body, and at their inner ends are pivoted to a bracket C carried by a beam J extending between the front and rear axles. Tilting of the vehicle body both transversely and longitudinally may be prevented by arranging any two of the above constructions, one transversely, the other longitudinally. The same result is given by the arrangement shown in plan in Fig. 9. Four pairs of rods A<11> arranged diagonally are disposed so that the two rods of each pair are one above the other. The outer ends of the rods are connected by springs F to brackets E arranged one at each corner of the vehicle frame, while the inner ends are pivoted to a central bracket C carried from the axles by the beams J, J'. In this arrangement, a single spring arranged between the central support C and the vehicle body may replace the four generally employed. In the other arrangements, the usual two springs on each axle may be replaced by a single spring arranged at the centre. Several forms of spring joints or rods are described for allowing slight momentary tilting. Springs or rubber cushions may be used, or the ends of the rods may be slotted, or the rods themselves may be made telescopic and provided with springs or rubber disks which resist only tensile stresses.
