Abstract

3589. Charley, J. J., [Charley, W. G.]. Feb. 11. [Cognate Application, 4848/13.] Equalizing load on wheels and springs; guiding vertical play; springs, arrangement of.-Vehicle suspension systems, of the type described in Specifications 12,913/11 and 15,590/11, are modified in regard to the location of the normalizing- springs. The axles are carried at the ends of horizontal resilient arms i of rockers pivoted to the sides of the chassis, and the vertical arm of each rocker is connected by a rod d to the vertical arm of the other rocker on the same side of the vehicle. Fig. 1 shows two forms of normalizing-device. In one form, a helical spring m is disposed between an abutment a<2> upon the chassis and an arm c<2> extending from the rocker. In the other form, an extension k of the resilient arm i of the rocker is connected to the chassis by an adjustable link k<1>. The extension k is preferably of greater elasticity than the spring i. In a modification, Fig. 3, the rockers are pivoted to brackets a<4> depending from the chassis, and, in order to maintain the movement of an axle in a vertical plane, more particularly in the case of a steering-axle, the resilient arm of the rocker may comprise two diverging curved members i<1>, i<2> pivoted to the axle at points i<3>, i<4> respectively as shown on the right of the Figure. For a non-steering axle, substantially straight springs i<1>, i<2> may be employed as shown on the left of the Figure. The vertical arm of each rocker may comprise a pair of divergent leaf springs r, the lower end of the inner spring being connected to a pin c<11> in the forked end c<12> of the rod d, and the lower end of the outer spring being connected to a pin c<10> carried by a link c<3> pivoted on the pin c<11>. Each normalizing-spring m<1> is disposed between an extension p of the rocker and a base o carried by a pivoted hanger n depending from the chassis. The tension of the spring m' may be adjusted by a screw q extending through the base o and bearing against a seating o<1> for the spring. Supplementary springs may be used with the normalizing-springs to come into action when the vehicle is unequally loaded. Adjusting height of body from ground.-This adjustment may be effected by a right and left hand screw coupling e in the rod d.
