Abstract
Abstract A device for stabilizing against roll in a vehicle has the longitudinally disposed central frame members and a rigid axle is attached at the outer end of each frame member. The central frame members are constructed as trapezoidal shaped torque frames tapering toward their inner opposed ends. The shorter parallel sides which are the opposed inner ends of the trapezoidal torque frames are pivotably mounted at their midpoints to the vehicle chassis and each central frame member is resiliently supported at the opposite longitudinal sides of the chassis by laterally attached links pivotably mounted on a torsion rod the ends of which are movably supported from the vehicle frame.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
98 words
In a device for stabilizing a vehicle against roll, said vehicle having a pair of longitudinally disposed central frame members, each having first and second ends, the first ends of said central frame members opposed from each other on the longitudinal axis of the vehicle, said vehicle having rigid axles and said axles each mounted on one of longitudinally disposed central frame members, means for pivotably connecting said central frame member opposed ends respectively to the chassis of the vehicle, and means for flexibly connecting said central frame member opposed ends to opposite longitudinal sides of the chassis.
Claim 2
Dependent Claim
98 words
In a device for stabilizing a vehicle against roll, said vehicle having a pair of longitudinally disposed central frame members, each having first and second ends, the first ends of said central frame members opposed from each other on the longitudinal axis of the vehicle, said vehicle having rigid axles and said axles each mounted on one of longitudinally disposed central frame members, means for pivotably connecting said central frame member opposed ends respectively to the chassis of the vehicle, and means for flexibly connecting said central frame member opposed ends to opposite longitudinal sides of the chassis.
Claim 3
Dependent Claim
43 words
In a device as claimed in claim 1, and further comprising a support beam extending transversely to the direction of movement of the vehicle provided on each of the first ends of said central frame members which extend substantially parallel to the chassis.
Claim 4
Dependent Claim
64 words
In a device as claimed in claim 2 and further comprising a torsion rod disposed between said support beams and substantially parallel thereto, said torsion rod having offset ends, said flexibly connecting means comprising means for pivotably supporting said offset ends from the vehicle chassis and means comprising laterally offset links for pivotably connecting said torsion rod to each of said central frame members.
Claim 5
Dependent Claim
27 words
In a device as claimed in claim 3 wherein said pivotably supporting means comprises swiveled bearings and said offset ends being axially displaceable in said swivel bearings.
Claim 6
Dependent Claim
54 words
In a device as claimed in claim 3, wherein said offset links each comprise a bushing and a pivot pin extending therefrom substantially perpendicularly to the rotary axis of the respective bushing, said pivot pins being pivotably supported in said respective support beams, said bushings being axially displaceable and rotatable on said torsion rod.
Claim 7
Dependent Claim
35 words
In a device as claimed in claim 3, wherein said pivotably supporting means comprises swiveled bearings mounted on said chassis and supporting links connecting said offset ends of said torsion rod to said swiveled bearings.
Claim 8
Dependent Claim
30 words
In a device as claimed in claim 1, wherein said central frame members and their axles mounted thereon each have the shape of a trapezoid tapering towards said opposed ends.
Claim 9
Dependent Claim
74 words
In a device as claimed in claim 1, wherein said central frame members each comprises a torsion tube disposed along the central longitudinal axis of the vehicle, a supporting arm extending laterally from the opposed end of each of said torsion tubes, a torsion rod disposed between said opposed ends of said torsion tubes and at right angles thereto, and means for pivotably and axially displacably connecting said supporting arms to said torsion rod.
Claim 10
Dependent Claim
60 words
In a device as claimed in claim 2, wherein each of said support beams has a lateral extension therefrom, a balance arm having a pair of lever arms and pivotably mounted on a horizontal shaft extending laterally of the vehicle chassis, and means for pivotably connecting each of said support beam extensions to a respective one of said lever arms.
Claim 11
Dependent Claim
56 words
In a device as claimed in claim 2, and further comprising a balance arm having a pair of lever arms and pivotably mounted on a horizontal shaft extending laterally of the vehicle chassis, and means for resiliently connecting each of the support beams of said central frame members to a respective one of said lever arms.
Claim 12
Dependent Claim
80 words
In a device as claimed in claim 1, wherein each of said central frame members comprises at least one side beam, a torsion rod disposed between the opposed ends of said central frame members and substantially parallel thereto, said torsion rod having offset ends, means for pivotably supporting said offset ends from the vehicle chassis, and means comprising oppositely directed links for pivotably connecting said torsion rod to a respective one of said side beams of said central frame members.
