In an attempt to obtain the advantages with respect to steering arising from such a mounting of the front wheels and also to obtain the advantages arising when the vehicle is passing a' rough road from independently spring-supported wheels, vehicles have been constructed in which both rear wheels and front wheels have been mounted in the manner described. Vehicles thus road well and the comfort of the occupants is diminished because of a tendency which they show to accentuated rolling movement and to a large lateral inclination as compared with ordinary motor cars. made by me have demonstrated that there was a serious error of conception in constructing cars in this manner and in accordance with my present invention '1 have therefore provided for independent mounting of the rear wheels in different manner.
The subject may be understood from the following analysis. Referring to Fig. 1, if we imagine the vehicle shown as turning a corner, the body of the car under the influence of force will lean over towarfi the outside of the curve and take an inclined position, as shown in The wheels 1, however, because of their method of mounting remain in planes equidistant from the central plane of the body.
the body inclines, the front wheels I inclined position. The resistance of the road acts at the ground-engaging portions of the tires and the wheels tilt laterally about these points as the road. The bodyof the car follows the movement of the wheels and pivots about a point J also located on the road surface.
Now, if the rear wheels are similarly arranged,
the axis of motion of the car body as a whole is 45 over 10 constructed, however, do not hold the The scientific experiments a quite centrifugal Consequentpivots located on the surface of being relatively remote from wheels 2 so as to permit angular so swinging movement of their to the central longitudinal planes with respect plane of the body.
It will be apparent that since the wheels 2 are independently mounted they may move to pass over obstacles without tilting the body, as shown in Fig. 6. Under conditions such as above described tending to tilt the body the action at the The said two centers of movement J and J1 define an axis about which the body as a whole swings,whichislineJ JiinFig.2. IfGis the center, of gravity. the lever arm through my invention, therefore, is stable against overturning movesuspension and the steering advantages of constructions of the type illustrated in Fig. 1.
As seen from the location 01" the line J-J1 in Fig. 2, if the height of the center above ;the road s length of the lever location of the center of gravity, I prefer to locate this cenble towards the rear or at least rearwardly of the central transverse plane M-M.
I am aware that the invention may be 'em-' bodied in other specific forms without departing from the spirit or essential attributes thereof, and 'I therefore desire the present embodiment to be considered in all respect as illustrative and not restrictive; reference being bad to the appended claims rather than to the foregoing description to indicate the scope of the invention.
