Abstract
A suspension system for a vehicle comprising a frame, a load area on the frame, an engine mounted intermediate the front and rear ends of the frame. Closely spaced rear wheels are resiliently mounted at the rear of the frame. A front axle supports steerable front wheels and the front axle is resiliently mounted on the frame for movement vertically and horizontally. The mechanism is interconnected with the front axle such that when the steering is actuated, the frame is caused to tilt in the direction of the turn.
Claims12
A vehicle comprising
- a frame having a front end and rear end,
- a load area on said frame,
- an engine mounted intermediate the front and rear ends of said frame,
- closely spaced rear wheels resiliently mounted at the rear of said frame at a spacing less than the width of the frame,
- a front axle,
- steerable front wheels on said axle,
- means for universally mounting said front axle on said frame for movement vertically and horizontally,
- resilient means between said frame and said front axle,
- a steering column rotatably mounted on said frame,
- the position of the load, frame and engine being such that the majority of the weight of the load, frame and engine lies below an axis extending from the resilient means and intersecting the axis of rotation of the rear wheels when the vehicle is at rest,
- and means interconnecting said steering column and said front axle such that when said column is rotated, the frame is caused to tilt in the direction of the turn.
