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.
A vehicle including, in combination, a frame, an engine mounted to said frame, a first wheel, means coupled to said frame for pivotally supporting said first wheel proximate an extremity of said frame, second and third wheels having stub axles disposed in a mutual, horizontally-shifting vertical plane, said stub axles each being provided with driven power means, differential structure having transmission drive line structure coupled to said engine and a pair of axially aligned, oppositely extending axles each having drive power means coupled to said driven power means, a pair of housing arms disposed on opposite sides of said vehicle and respectively encasing said drive and driven power means, a pair of pulleys fixed to respective ones of said housing arms and being journaled with respect to said oppositely extending axles, a pair of pulley sets each having a fixed vertical axle and upper and lower idler pulleys horizontally mounted thereto, flexible elongate connector means keyed to and intercoupling said housing pulleys and having upper and lower courses traversing about said upper pulleys and said lower pulleys of said pulley sets, respectively, whereby a vertical movement of one of said second and third wheels will produce an opposite, compensating vertical movement in the remaining of said second and third wheels such that said oppositely extending axles always remain essentially horizontal, and means for releasably locking said flexible elongate connector means against movement, whereby to temporarily essentially fix the relative mutual disposition of said housing arms.
A vehicle including, in combination, a frame, an engine mounted to said frame, a first wheel, means coupled to said frame for pivotally supporting said first wheel proximate an extremity of said frame, second and third wheels having stub axles disposed in a mutual, horizontally-shifting vertical plane, said stub axles each being provided with driven power means, differential structure having transmission drive line structure coupled to said engine and a pair of axially aligned, oppositely extending axles each having drive power means coupled to said driven power means, a pair of housing arms disposed on opposite sides of said vehicle and respectively encasing said drive and driven power means, a pair of pulleys fixed to respective ones of said housing arms and being journaled with respect to said oppositely extending axles, a pair of pulley sets each having a fixed vertical axle and upper and lower idler pulleys horizontally mounted thereto, and elongate connector means keyed to and intercoupling said housing pulleys and having upper and lower courses traversing about said upper pulleys and said lower pulleys of said pulley sets, respectively, whereby a vertical movement of one of said second and third wheels will produce an opposite, compensating vertical movement in the remaining of said second and third wheels such that said oppositely extending axles always remain essentially horizontal, and wherein said vehicle is provided with actuatable means for selectively arresting elongate connector means movement, and wherein one of said courses includes a chain segment, said actuatable means including a journaled, reciprocable rod provided with end jaw means for engaging said chain segment, and fulcrumed lever means pivotally coupled to said rod for selectively advancing said jaw means toward said chain segment.
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, 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 shafts:
