The apparatus has two tilting wheels which, when
attached to a two-wheeled vehicle such as a motorcycle or a scooter, allows
the vehicle to tilt into a curve notwithstanding the addition of the two wheels.
The apparatus includes a frame, a pair of wheel supports and a pair of wheels
each rotatable about a separate wheel support. A pair of links interconnect
the frame with the wheel supports. The apparatus includes a rocker pivotally
connected to the frame and a pair of transverse arms each pivotal about a
separate wheel support and the rocker. Each transverse arm has a coil spring
for biasing the wheel support and rocker apart. When a vehicle equipped with
the apparatus rounds a curve, the frame tilts in the direction of the curve
with like tilting of the wheels of the apparatus. |

with the wheels and control means selectively operable to operate a
changeover valve (25) to cause the dampers (17, 18) to operate either
independently or simultaneously to alter the operating characteristics of the
suspension. In one position of a changeover valve (25), chambers above and
below pistons (17b and 18b) are interconnected for each damper to allow
normal tilting of the vehicle while still permitting suspension movements. In
a second position of the changeover valve (25), the chamber above piston
(17b) is interconnected with the chamber below piston (18b) and the chamber
below piston (17b) is interconnected with the chamber above piston (18b),
thereby preventing further tilting of the vehicle, whilst maintaining full

comprising a rigid frame (17) adapted to be firmly fixed to the chassis of
the vehicle so as to be tilted together with the whole vehicle and a tilting
arm (14) pivotally linked to said rigid frame. The tilting of the rigid frame
is obtained as a result of the counter torque arising when activating
hydraulic actuating means (101, 102) pivotally interposed between said
tilting arm (14) and said rigid frame (17), with said tilting arm being
pivotally connected to shock absorbers (18). The tilting module further
comprises suspension arms (10, 11, 12, 13) pivotally connected to the rigid
frame, with said suspension arms supporting, in cooperation with supporting
uprights, the two wheels thus allowing both tilting and steering of said two
wheels.; The hydraulic actuating means (101, 102) are actuated by an
hydraulic pump (112) driven by an electric motor (108). |

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 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. |

In this vehicular chassis system, the vehicle's
passenger compartment and wheels incline toward the turning center side in
such a manner, that the wheels can be tilted independently from steering.
This vehicle has a steering apparatus controlling the steering, and a
separate apparatus controlling the lateral leaning. The lean is controlled
mechanically using a pendulum, and forced lateral leaned using a control
unit, or manually with the transfer of body weight using several pinions with
a set ratio to control the passenger compartment lateral lean in conjunction
with the wheel lateral lean.; An electric DC servo gear motor can be used to
control the lateral lean, that intern moves a pinion, which moves a rack and
lateral movable cross member, while controlling the lateral leaning wheels
and pulling the tilt support bar pivotally attached to a passenger
compartment in the same leaning direction. |

This invention relates to wheeled vehicles and
particularly to motorised road vehicles. The wheeled vehicle (10) includes
two frames (12) for carrying road wheels (18, 20), the frames (12) being
laterally spaced apart. A pair of road wheels (18, 20) are mounted on each
frame (12) for supporting that frame (12) on the ground, the wheels (18, 20)
of each pair being mounted for rotation about operatively more or less
horizontal rotational axes which are spaced apart along the associated frame
(12). A motor (36) is connected by a drive train (48, 28, 30, 32) to a rear wheel
(20) on each of the wheeled frames (12). The wheeled frames (12) are
connected together for synchronous tilting relative to the vertical, so that
the camber angles of all the wheels (18, 20) change in response to lateral
tilting of the frames (12). |

The vehicle, which has at least one rear wheel (5a,
5b) and two front wheels (6a, 6b), has a system that allows its body and
chassis to tilt on bends so that the wheels on one side are above and the
wheels on the other side are below a reference plane (Pr) perpendicular to
the saggital plane of the chassis. The tilting movement is produced when the
steering handlebar (15) is turned to left or right, by means of a steering
bar (12) connected to the wheel hubs by horizontal arms (9a, 9b) and vertical
rods (16a, 16b) in guides (17a, 17b), and a connecting piece (14) between the
bar (12) and the steering column (13). |

A vehicle suspension system is provided for tilting a
chassis 24 with respect to the axes of vehicle wheels 31 and 32 during
cornering to improve the comfort of travel for occupants of the vehicle. A
lateral or centrifugal force sensor mounted to the chassis 24 provides a
control for a hydraulic pump to cause a piston 15 in a cylinder 14 to move to
the left or right. The Figure shows the piston 15 to the left of a mean
central position and its movement has caused the chassis to tip to the right.
The vehicle in the Figure is shown moving away and to the right. For the
corner, the tilt is stable as the sensor will remain balanced, that is not
then generating further or extra tilting, until the degree of cornering
changes or the vehicle straightens out. In the latter case, the sensor will
respond to cause the piston 15 to move to its central position and the
chassis to level off. |

The invention of this particular vehicle, due to its
special characteristics, is an important innovation in solving the problems
of traffic jams and parking spaces. It has the manoeuvrability of a motorcycle,
and all the comforts of a car. Its characteristics are: 1) reduced size, with
seats (preferably three) positioned in a longitudinal direction; 2)
inclination of the vehicle through the internal side of the curve (such as
with a motorcycle). The second point is possible because of the anti-rolling
system. It works by a system of ascending and descending wheels; ascending if
they are internal to the curve, descending for the outside, controlled by the
driver with a common bar normally used on motorcycles. The same bar can also
be inclined to lean the vehicle either to the left or to the right. This
system can also be used in traditional cars, off-road vehicle and
three-wheeled vehicles, as it would improve their safety in curves at higher
speeds. |

The suspension includes a pair of arms independently
pivoted to opposite sides of the vehicle chassis at one end for up-and-down
movement, each arm rotatably carrying a ground-engaging wheel of the vehicle
at its free end. Each arm extends in the same direction from its pivoted end,
longitudinally of the chassis. A compression spring contacts and upwardly
extends from each arm at a distance from its pivoted end, and a load transfer
lever is fulcrumed at its center to the chassis; extends transversely of the
latter; and its outer ends overly and contact the top of the respective
compression springs. The suspension system is applicable to three- and
four-wheel motor vehicles. Preferably, the arms are hollow and serve to house
part of a transformation mechanism to the wheels, the latter being the
driving wheels.; In a four-wheel vehicle in accordance with the invention,
there is further provided an additional load transfer lever disposed on each
side of the vehicle chassis and extending longitudinally of the same, with
their ends underlying and having a slidable connection with the first-named
transfer levers adjacent the springs. |

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. |

Telescopic members (241, 242) which are expanded and
contracted by means of a fluid pressure controlled by a steering mechanism
(20) are integrally connected to suspension springs (141, 142). When a
vehicle makes a turn, the body is caused to decline toward the turning center
side due to the telescopic movement of the telescopic members according to
the steering operation. The fluid pressure may be fed from a hydraulic
cylinder (26) including a piston (27) associated for movement with the
steering mechanism. Alternatively, fluid pressurized by a pump may be fed
through a controlling valve which is actuated in response to the steering
mechanism. At a time when the vehicle makes a turn, a satisfactory steering
sense similar to a motorcycle can be obtained. |
