7 Claims. (Cl. 280-—S6.1)
My invention relates to an apparatus for bank
ing the front wheels of a vehicle when turning
a corner with the vehicle to affect the direction
of the stresses and prevent the collapse of ‘the
front wheel, particularly when making short,
rapid turns, and the objects of my invention are:
First, to provide a front wheel axle and wheel
support for vehicles which automatically banks
the wheel with the turning of the vehicle;
Second, to provide a front vehicle banking ap
paratus in which the support between the wheel
steering knuckle and axle is shifted from a sub
stantially vertical to an inclined position upon
the operation of the steering knuckle arm in con
' nection with the steering knuckle so as to bank
the wheel when turning;
Third, to provide an axle and wheel steering
knuckle connection for the front wheels of ve
hicles in which the wheel is banked in direct pro
tion with the wheel in banked position; Fig. 5
is a diagrammatic View showing the wheels in an
assumed proper banked position, the angle B be
ing the assumed proper angle; and Fig. 6 is a '
diagrammatic view showing the'forces operative‘ 5
‘on a vehicle for indicating the proper banking
angle, the line of force indicatingthe arrow at
the top by centrifugal force while at right angles
thereto is weight and gravity force while the line
It is the assumed proper angle for the banking l0 '
of the wheel 7.

The main front axle I, ball member 2, thrust‘ 15

knuckle arm 8 constitute the principal parts and
portions of my vehicle front wheel banking ap

vehicle are angled in the right proportions and
in the right direction for affecting the direction
of the stresses and preventing the collapse of the
wheels when making short rapid turns;

which the front axle and wheel steering knuckle
may be substantially conventional with but slight

and arrangement of parts and portions as will
