Abstract
Abstract A balance suspension system for three-wheel vehicles wherein such system is applicable in particular to the oppositely-reciprocating related wheels of the vehicle. The system is designed such that the vehicle tends to maintain an essentially horizontal position, relative to its transverse axis, even though wheels may pass over bumps or dips or the vehicle itself may be traversing sloping terrain. Structure is provided such that a vertical movement in one of the oppositely-reciprocating wheels is offset by an opposite movement in the remaining wheel whereby the transverse axis of the vehicle is essentially maintained on a horizontal axis. Such precludes the vehicle from dipping or spilling. Further provision is made so that, as the vehicle is cornering, the transverse orientation of the vehicle dips inwardly, tending to oppose centrifugal force and thereby maintain the integrity of vehicle travel. Power balancing is also supplied.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
176 words
In a vehicle having a motor, a transmission coupled to said motor, a differential having oppositely extending axle shafts and coupled to said transmission, axle shaft housing means encasing said axle shafts and nominally horizontal when said vehicle is erect, a pair of opposite wheels, and side-opposite lever structures pivotal with respect to said axle shaft housing means for supporting said wheels and also for operatively coupling said wheels to said axle shaft; an improvement comprising intercoupling means intercoupling said side-opposite lever structures for effecting corresponding counter-movements in said lever structures and said wheels, and power balance means coupled to said intercoupling means and responsive to any tilt from the horizontal of said axle shaft housing means for actuating said side-opposite lever structures to reorient said wheels such as to reorient to an essentially horizontal position said axle shaft housing means, and means for selectively disengaging said power balance means, and wherein said intercoupling means includes a pair of gear elememts mutually pivoted together and provided with shock absorbing resilient means disposed between said gear elements.
Claim 2
Dependent Claim
176 words
In a vehicle having a motor, a transmission coupled to said motor, a differential having oppositely extending axle shafts and coupled to said transmission, axle shaft housing means encasing said axle shafts and nominally horizontal when said vehicle is erect, a pair of opposite wheels, and side-opposite lever structures pivotal with respect to said axle shaft housing means for supporting said wheels and also for operatively coupling said wheels to said axle shaft; an improvement comprising intercoupling means intercoupling said side-opposite lever structures for effecting corresponding counter-movements in said lever structures and said wheels, and power balance means coupled to said intercoupling means and responsive to any tilt from the horizontal of said axle shaft housing means for actuating said side-opposite lever structures to reorient said wheels such as to reorient to an essentially horizontal position said axle shaft housing means, and means for selectively disengaging said power balance means, and wherein said intercoupling means includes a pair of gear elememts mutually pivoted together and provided with shock absorbing resilient means disposed between said gear elements.
Claim 3
Dependent Claim
49 words
The structure of claim 1 wherein power balance means comprises an arm having a gear segment motor means provided with output gearing engaged with said gear segment, said arms being backed on opposite sides by said resilient means, said power balance means consisting in part of said motor means.
Claim 4
Dependent Claim
46 words
The structure of claim 2 wherein said motor means comprises a fluid motor, said power balance means also including electric motor means responsive to said tilt to drive said fluid motor in that direction requisite to restore said axle shaft housing means to essentially horizontal condition.
Claim 5
Dependent Claim
26 words
The structure of claim 2 wherein said selectively disengaging means comprises means for effecting the selective disengagement of said gearing with respect to said gear segment.
