Four-wheel steering, leveling and banking for vehicles

A vehicle having a steering wheel, a frame, left and right front wheels, and left and right rear wheels, said frame having a longitudinal axis and a transverse axis, comprising,

• a front steering means operatively linked to a steering wheel for turning left and right front wheels in response to rotation of said steering wheel,
• a rear steering means operatively linked to said steering wheel for turning left and right rear wheels in response to rotation of the steering wheel,
• front camber adjustment means operatively linked to said front wheels for transmitting rotary rotation to said left and right front wheels, said front camber adjustment means including a left suspension arm attached to the left front wheel and a right suspension arm attached to the right front wheel, said left and right suspension arms each pivotally connected to a vehicle frame opposite the associated wheel, said front camber adjustment means being responsive to a fluid working medium to cause rotary motion of aid front wheels relative to the longitudinal axis of the vehicle frame,
• rear camber adjustment means operatively linked to said rear wheels for transmitting rotary motion to said left and right rear wheels, said rear camber adjustment means including a left suspension arm attached to the left rear wheel and a right suspension arm attached to the right rear wheel, said left and right suspension arms each pivotally connected to the vehicle frame opposite the associated wheel, said rear camber adjustment means responsive to a fluid working medium to cause rotary motion of said rear wheels relative to the longitudinal axis of the vehicle frame,
• attitude adjustment means connecting said front and rear wheels to said vehicle frame for controlling the distance between a wheel and said vehicle frame, said attitude adjustment means actuated by a fluid working medium,
• supply means for providing said fluid working medium,
• valve means for directing fluid flow of said fluid working medium between said supply means on the one hand and said front and rear adjustment means and said attitude adjustment means of the other hand, and
• a pendulous mass pivotally suspended from said vehicle frame and operatively connected to said valve means for regulating the orientation of each wheel, said pendulous mass disposed to pivot in response to the magnitude of lateral acceleration of a vehicle and in response to the vertical position of the right front and rear wheels relative to the left front and rear wheels.
