The present invention relates to a wheel tilting system
for vehicles with three or more wheels, wherein at least two wheels are
interconnected on the same axle. The system according to the present
invention enables a variation in the attitude of the vehicle that can be
selectively established in tilting or non-tilting mode without the disabling
of the vehicle tilting system interfering with the shock absorbing effect of
the vehicle's suspension system. The system in question consequently combines
the advantages of the simplicity and compact size of a hydraulic system in
which the tilting and the shock absorption of the wheels are controlled by an
integrated system of hydraulic cylinders, with the versatility of a system
affording the opportunity to choose the attitude of the vehicle. |

A three-wheeled motor vehicle with front steering wheel
5 and transversely spaced apart rear driving wheels 6,7 on controllable, with
sufficient freedom of oscillation in opposite directions, suspension
structure. The driver-operated pedals 22 manually change the geometrical
configuration of the rear suspension and incorporate with computer control
electromechanical gear motor power-assisted force of the pedals and provide
ride-by-wire mode, controlling vehicle in vertical position. When the pedal
22 is depressed, a toothed pawl 17 slides along a bracket shaft 16, which is
held in position by a return spring (fig 6, 20) and engages with a toothed
plate on a rocker arm (fig 6, 9). The pivotal movement of the rocker arm (9)
is transferred to synchronous movements of the swing arms (fig 3, 8) in
opposite directions to produce lateral tilt of the vehicle. |

A vehicle with increased turning ability. When the vehicle
turns, left and right wheels are moved relative to a vehicle body in the
top-bottom direction, and this causes the body and the left and right wheels
to tilt to the inside of the turn. This causes force acting on a vehicle
occupant to be in the top-bottom direction of the occupant, reducing
unpleasant feeling of the occupant. Also, since the center of gravity of the
vehicle moves to the inside of the turn, turn stability is increased. |

The invention relates to a curve-tilting vehicle,
e.g. a three-wheeled vehicle (30), comprising means for laterally tilting (4)
at least one section (5) of the vehicle by a tilting axis (6) that runs
substantially parallel to the longitudinal axis (3) of the vehicle such that
the center of gravity of the vehicle can be displaced perpendicular to the
direction of travel when driving, especially in curves or on a sloped or
uneven ground. The inventive vehicle comprises at least one vehicle seat (8a)
that is disposed in the tilting section (5) of the vehicle and is allocated
to the driver who steers the vehicle. The vehicle further comprises means
(9a) for detecting a lateral force of the seat, which the body of the driver
applies at least to one zone of the vehicle seat (8a) in a lateral direction
(10a) extending perpendicular to the direction of travel.; In one embodiment,
the lateral force of the seat is detected using a pivotable spring-centered
vehicle seat (8a). The detecting means (9a) are effectively connected to the
lateral tilting means (4) in such a way that lateral tilting occurs in
accordance with the detected lateral force of the seat while the tilting
speed is a function at least of the lateral force of the seat and the vehicle
speed, the tilting speed increasing as the lateral force of the seat rises at
a factor that decreases as the speed of the vehicle goes up. The invention
further relates to a method for tilting such a vehicle. |

Perfectionnement
à la suspension d'un véhicule inclinable à trois roues.La présente invention a
pour objet un perfectionnement à la suspension d'un véhicule inclinable à
trois roues. Ce perfectionnement permet de limiter les efforts dans les
moyens amortisseurs, autorise une variation de la raideur de la suspension
face à une évolution de la charge à laquelle elle est soumise et permet une
grande liberté de positionnement des moyens amortisseurs.La suspension est
constituée d'un levier (22) dont une extrémité est montée à pivotement par
rapport au bâti tubulaire (2), l'autre extrémité de ce levier (22) étant
reliée de façon articulée à une extrémité des moyens amortisseurs (16),
l'autre extrémité desdits moyens amortisseurs (16) étant reliée dé façon
articulée au bâti tubulaire (2), ce levier (22) étant, entre ses deux
extrémités,; monté à pivotement sensiblement au milieu de la barre de liaison
transversale (15).La présente invention s'applique préférentiellement à un
véhicule destiné à un usage routier, mais peut aussi être appliquée à tous
types de véhicules inclinables à trois roues ou plus, à des engins destinés
aux loisirs ainsi qu'à des jouets ou à des modèles réduits. |

PROBLEM TO BE SOLVED: To obtain traveling property,
stability, and safety which are equal to or more than those of a two wheeler
during traveling by connecting two rear wheels by a differential gear and
connecting a differential central part of the differential gear on the center
of gravity of a vehicle body directly or by a buffer device to suspend two
wheels in a two rear wheel suspension method. SOLUTION: Two rear wheels 1, 2
are set to swing arms 3, 4, the swing arms 3, 4 are connected by differential
gears 5, 6, 7, and a bearing 8 which rotates a pinion 6 freely is connected
by a fixing or buffer device 9 on the center line or the line of center of
gravity of a vehicle body frame 10.; When there is a projection on a road and
one wheel rides over it, force raised by the differential gears 5, 6, 7 set
to the swing arms is received from both wheels, the force is transmitted from
the pinion part 6 to a vehicle body and is supported by a part 11 of the
pinion part 6 on the center line or the line of center of gravity. As is
shown by the vehicle body which rides over the projection on the road, its
travel amount is reduced to a half by the differential gears, and it is more
stable than a two wheeler. |

|
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. |

The "articulated balancer with oscillating axle
and having locking possibilities" provides dynamic stability and static
balance in curves to light-weight, narrow vehicles having a high center of
gravity. Its application focuses on a vehicle having three wheels, one in
front and two in the rear, which vehicle rivals in its maneuverability a
motorcycle, offering a higher levels of safety and convenience than
conventional motorcycles. The stability in curves is obtained by enhancing
the lateral tilting of the vehicle. For this, each rear wheel must allow an
up or down motion; each of these motions is opposite to the other but to the
same extent. By means of "ball-and-socket" hinged joints, two
connecting rods connect the balancer with the rear swinging forks, converting
the balancer's rotation to an up-and-down motion of the latter.; The balancer's
axle allows an oscillation motion controlled by a shock absorber, that
provides the rear suspension of the vehicle. The static balance and certain
characteristics of its dynamic behavior are obtained by locking the rotating
of the balancer. |

A three-wheel vehicle apparatus has one front wheel
and two rear wheels to improve safety of operation, including a novel
tilt-and-bank mechanism, front wheel suspension, safety frame, aerodynamic
body design, and sliding doors. The tilt-and-band mechanism employs a tilt
bar connected to hydraulic cylinders and spring/shock units mounted on the
wheels which automatically tilt and bank the vehicle in turns. The front
wheel suspension mounts the front wheel on a trailing arm and uses a reaction
arm connected to a pivot pin in front of the wheel for better handling of
centrifugal forces in turning. The safety frame employs three crosswise roll
bars connected together by three longitudinal bars and connectors, all in
turn connected to a complete wraparound bumper.; This vehicle is made
aerodynamically more efficient by a pointed nose and a new upswept tail that
eliminates rear drag at high speeds. Additionally, doors which can be opened
and remain open at high speeds are roller mounted on the outside of the passenger
compartments. The improved vehicle is designed to make the use of three-wheel
vehicles on today's highways safe and reliable. |

The vehicle is equipped with a front wheel 1 and with
two rear wheels 2 and 3, with a rear suspension equipped with a balance arm 8
the rotation of which brings about the inclination of the vehicle, controlled
by a double-acting hydraulic thrust cylinder 9 supplied by the output from a
pump passing through a distributor controlled by the driver. The hydraulic
circuit operates as an open centre; it is equipped with controlled non-return
valves on each supply to the thrust cylinder 9. The control circuit for the
valves is equipped with solenoid valves allowing them to be isolated, when
stationary and at low speed, beyond an inclination threshold given by
end-of-travel sensors arranged on the rod of the thrust cylinder 9.; Beyond a
speed threshold, the effect of the valves is cancelled out by virtue of a pressure
difference generated by the presence of a nozzle on the return to tank
circuit, the effects of which are managed by a solenoid valve which is
controlled by electronics 25 interpreting the signals from a speed sensor 26
located on the front wheel. In the same way, the supply to the end-of-travel
sensors is eliminated so that the inclination is no longer limited. |

This invention relates to an inclinable vehicle
having three or more wheels. The invention provides a stabilizer system for
the vehicle so that the stationary vehicle does not fall. The vehicle comprises
a primary part including two wheels (1a, 1b) and a distortable suspension
structure (2) connecting the wheels, and a structural member (4) mounted on a
chassis member to tilt with the suspension structure. The tilting rotates an
arm (5) with a multiplication ratio, and a roller on the arm (5) runs on a
cross-member (19). The secondary part (6) of the vehicle slides on the
structural member (4) and is carried by the cross-member (19) so that
rotation of the arm (5) on tilting of the vehicle lifts the secondary part
and raises the overall center of gravity of the vehicle. In a varient, the
rise of the center of gravity is obtained by rotation of the secondary part
of the vehicle.; A clutch may be provided to disengage the stabilizer while
the vehicle is moving. |

In order to eliminate the risk of the motorcycle
falling over and the three-wheeled vehicle tipping over, the two rear wheels
of the scooter with a cab swing parallel to the plane of symmetry of the vehicle,
the style of driving the motorcycle is preserved, the vehicle enters at an
inclination (optionally up to a stop) into the curve. In the position of
rest, the vehicle is locked against inclination to the side, it behaves,
likewise in first gear, as a three-wheeled vehicle. On changing up to second
and the higher gears the lock is released, the vehicle then behaves as a
motorcycle. When changing down to first gear the lock again comes into
operation, the vehicle can be parked as a three-wheeled vehicle. By means of
two pedals coupled to the rear wheels the driver may at any time also have an
influence on the position of the vehicle. The feet are no longer used for
support on the ground, the vehicle may be provided with any desired
protection against the weather up to the vehicle body being fully closed
(with heating), already tested in 1946 (including two people spending a night
in the vehicle). |

A narrow track cambering vehicle having a steerable
front wheel and a pair of laterally separated rear wheels suspended on
trailing arms mounted for independent swinging movement in separate and
parallel planes. The arms form part of a cambering system controlled by
cables and tillers actuated by foot pedals which allow the operator to vary
vehicle camber independent of steering to maximize vehicle cornering through
a wide range of turns at varying speeds. |

The invention covers an apparatus to reduce the effect
of lateral forces during turns and/or one-sided or uneven loads on persons in
a vehicle, whereby the chassis is provided with a feeler responding to
lateral acceleration and inclination respectively, and the initial signal of
a regulator arranged at the starting point of the feeler influences the
device to tilt the chassis versus the carriage around an axis which is
parallel with the longitudinal axis of the vehicle. |

An independent rear suspension and drive system for
a motorcycle having a steerable front wheel and a laterally mounted pair of rear
wheels, including a transverse driveshaft having a differential connection
with the engine, a pair of trailing-links journaled on the drive-shaft and
mounting the respective rear wheels pivotally about the driveshaft, a pair of
driveshaft output sprockets respectively on opposite sides of the
differential, a pair of chains operatively connecting the driveshaft output
sprockets with respective wheel drive sprockets, and a transverse arm
centrally pivoted to the frame and having at each end a dashpot connecting to
a respective trailing link; associated dashpot spring means is arranged to be
determinative of the combined trailing link positions relative to each other,
but not to the motorcycle frame. |

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. |
