Abstract
Abstract External forces acting upon a vehicle during movement along a curve or turn are counteracted and provide body banking by a body tilting or banking mechanism comprising a means for counteracting the external tipping forces which means may include an inclined plane, or matching inclined plane members having a common axis so that movement of one with respect to the other will cause a tilt of the vehicle in the direction opposite that caused by the external tilting force. This means may be conveniently positioned and, for example, connected with the steering control of a vehicle or in a hinged vehicle such as a semi-trailer, it may be made a part of the interchange coupling between tractor and trailer. The means may include an inclined plane bearing against a movable axle means and may take the form of a hydraulic means operated off of a master cylinder.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
292 words
In a self-contained body banking mechanism for a steerable vehicle under direct control of the steering linkage for the vehicle, the vehicle having a body including a frame, front steering wheels and rear traction wheels and axles therefor supporting said frame and body, individual cylinders and pistons longitudinally pivoted on said front and rear axles and supporting opposite sides of said frame on said axles, fluid pressure means maintaining fluid under pressure in said individual cylinders and pistons and supplying fluid under pressure to said individual cylinders and pistons associated with said front and rear axles on one side of the body and releasing fluid under pressure from the cylinders and pistons on the opposite side of the body, comprising at least one double-acting master cylinder having a double-acting piston therein and fluid connections from opposite ends of said master cylinder to respective ones of said cylinders and pistons at opposite sides of the vehicle, a direct mechanical connection from said steering linkage to said double-acting piston for effecting movement of said piston along its cylinder to supply fluid under pressure to said cylinders on one side of the body and release fluid under pressure from said cylinders at the opposite side of the body comprising a rack rectilinearly guided along the outside of said master cylinder for movement along the axis thereof, pinion means meshing with said rack and directly operated by said steering means and a positive connection from said rack to said double-acting piston to move said piston along said master cylinder upon turning a corner to effect vertical movement of the body relative to each wheeL and axle in general vertical directions and tilt the vehicle body to bank the body in direct relation with respect to turning.

In a self-contained body banking mechanism for a steerable vehicle under direct control of the steering linkage for the vehicle, the vehicle having a body including a frame, front steering wheels and rear traction wheels and axles therefor supporting said frame and body, individual cylinders and pistons longitudinally pivoted on said front and rear axles and supporting opposite sides of said frame on said axles, fluid pressure means maintaining fluid under pressure in said individual cylinders and pistons and supplying fluid under pressure to said individual cylinders and pistons associated with said front and rear axles on one side of the body and releasing fluid under pressure from the cylinders and pistons on the opposite side of the body, comprising at least one double-acting master cylinder having a double-acting piston therein and fluid connections from opposite ends of said master cylinder to respective ones of said cylinders and pistons at opposite sides of the vehicle, a direct mechanical connection from said steering linkage to said double-acting piston for effecting movement of said piston along its cylinder to supply fluid under pressure to said cylinders on one side of the body and release fluid under pressure from said cylinders at the opposite side of the body comprising a rack rectilinearly guided along the outside of said master cylinder for movement along the axis thereof, pinion means meshing with said rack and directly operated by said steering means and a positive connection from said rack to said double-acting piston to move said piston along said master cylinder upon turning a corner to effect vertical movement of the body relative to each wheeL and axle in general vertical directions and tilt the vehicle body to bank the body in direct relation with respect to turning.
Claim 3
Dependent Claim
39 words
The vehicle tilting and banking mechanism of claim 1, wherein an individual master cylinder and double-acting piston is provided for each axle, and wherein said pistons are directly operated in accordance with steering through individual rack and pinion means.
