The present invention relates to a wheel tilting
system (1) for vehicles with three or more wheels in which at least two
wheels (30) are set alongside each other on the same axle. The tilting system
according to the present invention allows to contain the crosswise dimensions
of the vehicle by significantly reducing the track of the same. The vehicle
provided with the tilting system according to the present invention is highly
agile in city traffic due to its small dimensions, and rapid when changing
direction. Furthermore, the system in object is modular, by including
identical components of the tilting system on the right and left sides of the
vehicle and by providing that many details are repeated in the system, thus
obtaining advantages in terms of construction and maintenance simplicity and
cost-effectiveness. |

The necessity to get higher degrees of safety
through better stabilities of the "Scooter-Cyclemotor-
Bicycle-Motorcycle" has made theese 2 kinds of assemblies (front and rear)
. The Front assembly always has forwarding the" 2 steering, inclining,
shock-absorbing, braking, parallel front wheels" and with the already
existent 1 rear-wheel in the rear side, or with the Rear-assembly, that has
the"2 inclining, shock-absorbing, braking, parallel rear-wheels"
(Page :1 ,2,3,4,5,6,7. / 7) . Those 2 kind of assemblies are singularly, or
both, suitable to build a vehicle with' 3, or 4 wheels' (with 2 rear-wheels)
, always determining 3 or 4 points of contact on the ground (not only 2 ) .
The vehicle with '3, or 4 wheels' is safer, it's more vertical steady and
answers the highest degrees safeties either, with a second passenger on
board, or with major loads upon (like heavier accumulators use for electtric
or hybrid power and/or if it uses major load-structures like new body
carriage) . The vehicle is always safe especially when adverse
metheo-conditions happen (stormy weather, snowing, hailing etc.) , or in
specific unbalanced conditions (like in up or down dangerous pending roads "in
uphill or downhill") . Then the Front-assembly with, or w/o the
Rear-assembly offers the following advantages in : .A) STAND UP STABILITY in
' parking mode' .B) STAND UP STABILITY in ' marching and in turning mode'
(without or with braking) .C) AGILITY inside SECURITY either in th urban
traffic or in highways. .D) GOOD ROADABILITY. |

The present invention relates to a three-wheeled
vehicle comprising a frame with engane, drive gear and at least one driven
wheel at the rear, and two front wheels which are used in part to steer the
vehicle. The vehicle can also be steered in that the frame with engine, drive
gear and the driven rear wheel can be banked over to the side like a
motorcycle. The present invention relates in particular to a design which
helps to move the centre of gravity when such a vehicle is tilted to the side
so that, inter alia, it is easier to right the vehicle. Furthermore, the
present invention makes it possible to affect and determine the driving
characteristics of the vehicle by varying different design parameters within
the scope of the present invention.; The invention also relates to a special
design for the mounting of footboards on which the driver of the vehicle can
place his/her feet when driving the vehicle. The special design according to
the invention contributes actively to changing the geometry between the footboards
and the frazne of the vehicle when the vehicle is used and especially wheir
it is "tilted" to the side to steer the vehicle. |

A form of vehicular suspension which duplicates the
dynamic properities of a motor/pedal bikers suspension and which is also capable
of keeping the vehicle upright when it is moving slowly or is stationary is
achieved by having at least one pair of wheels 3 laterally disposed about the
vehicle's body 4 in conjunction with a mechanism connecting the wheel's
uprights and the body in such a manor as to allow them to rotate freely and
in unison about the wheel's contact points with the ground. Thus the machine
may be banked into corners like a bike. The vehicle's angle of lean is
controlled by use of wheel gyroscopic forces. At low speed and when
stationary the mechanism is locked in rotation relative to the body and thus
the vehicle becomes in effect a narrow car.; As the rider/driver does not
have to be able to touch the ground with his feet to stabilise the vehicle,
it may be fully enclosed, and therefore has the potential to be as safe as
car. |

Three or four wheeled vehicle which leans into
corners so as to remain stable even when the vehicle has a narrow track. The
steering mechanism is such that leaning of the vehicle to either respective
side of the vertical causes the front steering wheels (10) to turn in the
same steering direction, e.g. a lean to the left causes an anticlockwise,
when viewed from above, turning of the front wheels (10). The front wheels
(10) can be supported on a parallelogram linkage system (17, 18) so that the
steering axis (16) of the wheels (10) remain parallel with the vehicle body
as the vehicle leans.; Steering can be controlled through a steering wheel
(14) which, disregarding the influence of body lean, turns the front wheels
(10) in a steering direction relative to the turn of the steering wheel which
is opposite in sense, e.g. an anticlockwise turn of the steering wheel (14)
produces a clockwise turn, when viewed from above, of the front wheels (10).
In order to produce a predetermined steering characteristic the ratio between
the angle of lean of the vehicle and the responsive angle of turn of the
front wheels (10) varies with the forward velocity of the vehicle. |

The specification discloses a three-wheeled vehicle
with a steering mechanism configured and arranged to provide
driver-controlled wheel and body lean as the vehicle is making a turn. A
cradle is rotatably mounted at the front of the vehicle for rotation about an
axis generally longitudinal relative to the body. An axle connected to the
cradle is perpendicular to the axis of rotation of the cradle and a spindle
is pivotally connected to each end of the axle. A wheel is rotatably mounted
on each spindle. A tie rod pivotally connected at its ends to the spindles is
held in a selected position about the axis of the axle by a tie rod linkage.
A coupler rotatably connects the linkage to the body. The linkage is also
rotatably connected to the axle for rotation about an axis perpendicular to
the axle to move the tie rod laterally.; When the linkage is disposed to hold
the tie rod forward of the axle, a force causing rotation of the movement of
the tie rod laterally produces a conventional turning effect. When the linkage
is disposed to hold the tie rod vertically above the axle, movement of the
tie rod laterally causes the body to rotate about its connection to the
cradle by virtue of the coupler, and causes the wheels to lean, producing
simultaneous wheel and body lean. Locating the linkage to hold the tie rod in
an intermediate position produces a combined leaning and turning effect. |

PURPOSE:To enhance the turnability of a vehicle
having at least one set of left and right wheels in pair, by arranging such that
the vehicle automatically tilts toward the center of turn of the vehicle in
accordance with the steering operation of the vehicle so that control feeling
similar to a motor-cycle may be obtained. CONSTITUTION:When a steering wheel
20 is rotated in the direction (a) to turn a vehicle to, for example, the
right during running of the vehicle, a slide shaft 13 is moved leftward
through a pinion 18 to deflect a front wheel 1 rightward.; Further,
simultaneously hydraulic pressure is fed into a cylinder 23 in a suspension
device 14 on the left side (right side in the figure) through a fluid
change-over device (rotary valve) which is not shown and which is operated in
association with the rotation of the steering wheel while hydraulic oil is
discharged from a cylinder 23 in a right side suspension device 14. With this
arrangement, the left side cylinder 23 is moved upward while the right side
cylinder 23 is moved downward, thereby a vehicle body 2 is inclined rightward
or toward the center of turn through a lower arm 4 and an upper arm 6. |

A three-wheeled vehicle steering and suspension
system including two support assemblies for two opposed front wheels
pivotably mounted at opposite sides of the vehicle frame and operatively connected
by a hydraulic cylinder arrangement actuated by the vehicle steering linkage
for inducing opposed pivotal movement of the support assemblies during
vehicle turning to cause leaning of the vehicle in the direction of turning.
A biasing arrangement provides the operative connection between the hydraulic
cylinder and the support assemblies for transmitting lean-actuating
reciprocatory movement of the hydraulic cylinder to the support assemblies
while yieldably permitting independent pivotal movements thereof.; The
biasing arrangement may include respective torsion bars fixed at respective
ends thereof to the opposite ends of the hydraulic cylinder and at the other
respective ends thereof to the support assemblies, the torsion bars being
correspondingly rotated by the hydraulic cylinder to actuate the opposed
pivotal movement of the support assemblies. A shock absorber is mounted on
each torsion bar and extends therefrom to the respective support assembly for
dampening independent movements thereof without creating resistance to
rotation of the torsion bar by the hydraulic cylinder. Alternatively, the
shock absorber may provide the biasing connection between the hydraulic
cylinder and the support assemblies. An electro-hydraulic system actuates
reciprocation of the hydraulic cylinder in direct relation to the degree of
vehicle turning and to the vehicle speed. |

supporting means (3) being displaceable in unison by means of a common
steering device (12, 13, 14) and are each pivotally arranged on an extended
supporting arm (5) at the front part of the vehicle. The third supporting
means (4) being of a traditional nature of support only and each relevant
extended pivot (9) of the said two supporting means (3) lying in a common
plane which intersects the plane containing the said vehicle's two supporting
contact surfaces and the points of support, each extended pivot axis (16)
taking a rearward angle of inclination with respect to the vertical plane
through the longitudinal axis of the vehicle.; The points of intersection
(19) of each pivot axis (16) with the horizontal plane of support lying in an
outward direction perpendicular to the vehicle's longitudinal axis and
sidewardly and outwardly away from each of said points of contact whereby the
arrangement being suchlike that while the vehicle traversing a curved path,
the vehicle's frame is subjected to a "pendulum" action inthe
direction of turning. This "pendulum" actions causes a relative
different movement while progressively turning the vehicle's supporting means
located at the inner part of the curve moving more in a forward direction,
whereas the supporting means located at the outer part of the curve being
more retracted with respect to the said forward movement and vice versa. |

The present invention relates to a suspension and
steering system enabling the road holding, braking efficiency and safety of
presently known cycles and motorcycles of all types, on wheels or on skis, to
be increased, while maintaining their capacity to bank when cornering, their
handling ability and small dimensions. This system is composed of the
combination of two sub-systems:-the suspension sub-system intended to carry
two wheels or two skis, comprises: (a) a mechanism composed of two forks, two
pairs of guide shafts, and two supports. The forks move over the guide shafts
which are fixed to the supports; (b) a mechanism composed of a support, a
rocking arm and a handle bar.; This arm rocks on the axis of the support and
allows the interdependent displacements of the forks; -the steering
sub-system is intended on the one hand to carry the above mentioned
mechanisms of the suspension sub-system and on the other hand to be
articulated on the frame at the steering column and the reinforcing arm. It
is composed of the devices which form the central shaft. |

A wheeled vehicle includes a vehicle frame having at
least one wheel at one end of the frame and a hinged parallelogram frame mounted
on the other end of the vehicle frame and having a pair of spaced wheels
mounted on opposite sides thereof. The parallelogram frame will pivot
laterally in first or second opposite lateral directions when the frame leans
laterally away from a position of equilibrium in the first or second lateral
direction. A sensing device is connected to the vehicle frame and a power
source is connected to the sensing means and parallelogram frame whereby
initial leaning movement of the parallelogram frame in one direction (caused
by conditions of unequilibrium) will cause the sensing device and power
source to pivot the parallelogram frame in the opposite direction thereby to
laterally pivot the vehicle frame to a position of equilibrium.; The sensing
device may be a lever pivotally connected to the vehicle frame and the power
source may include a pair of extensible and retractable cylinder units for
connecting opposite ends of the sensor lever to opposite sides of the
parallelogram frame. |

A vehicle suspension system associated with a pair
of laterally spaced, steerable wheels includes novel wheel-control mechanism operable
in response to steering of the vehicle during a turn thereof for tilting the
outside wheel at a greater angle than the inside wheel in the direction of
the turn in order to automatically compensate for the effects of lateral
forces acting on the wheels which tend to be greater on the wheel tracking
the outside path of the turn compared with those forces acting on the wheel
tracking the inside path due to the lateral shifting of the vehicle's weight
as a result of body roll or the like. |

Abstract |

|
A device for automatically stabilizing moving ground
vehicles against the effects of transverse acceleration forces and roll moments,
due to turning maneuvers, by means of an on-board pendulum, suspended from a
stable platform, part of the vehicle, and intercoupled to pivotally supported
vehicle ground wheels, acting so as to incline the planes of rotation of the
pivotally supported ground wheels of the vehicle to the angle of the vector
resultant of the gravitational force component acting on the pendulum and the
transverse acceleration force component acting on the pendulum; the device
thereby provides, within the design maximum angle of inclination of the
ground wheels and the adhesion capability of the tires on the roadbed,
essentially complete stabilization of the turning vehicle.; The stabilizing
effect is that the angle of the force vector resultant acting on the vehicle will
nominally be that of the planes of rotation of the ground vehicle wheels,
excepting small steering and suspension system deviations that may act on the
steerable ground wheels or wheel. The vehicle is designed such that any
transverse forces acting on the vehicle automatically cause the vehicle to
lean, bank, or rotate about the longitudinal axis, much as a conventional
two-wheeled motorcycle leans on a turn, thereby establishing the necessary
angle of inclination required to balance the gravitational forces present and
the inertial forces generated by the turning maneuvers. |
