Mechanism for the construction of a three-wheeled vehicle
with front rolling part (1). The front part of the vehicle is linked to the
rear part (8) by a four-sided mechanism. During movement on a bend it is
inclined as normally takes place in two-wheeled vehicles, and the rear part
is not involved in the rolling movement. The mechanism is made up of four
members: one member known as the front frame (2) is connected to the front
rolling part of the vehicle, a second member known as the rear frame (5) is
connected to the non-rolling part of the vehicle, and the other two members
(3,4) that link the two frames determine the position of the roll axis (y) of
the front member with respect to the rear. The plane (v) on which the
mechanism is positioned is perpendicular to the longitudinal plane of the
vehicle. Variants will be produced. |

The invention relates to a vehicle (1) provided with
a frame having two frame sections (3, 4) which are able to tilt with respect
to one another. An opposite lock power transmitter (50) is connected to a
steerable front wheel (13). The opposite lock power transmitter (50) is
controlled as a function of the tilting moment on the frame sections (3, 4).
By this means application of opposite lock is achieved, as a result of which
the tilting section of the vehicles "drops into the bend" more
rapidly and as a result of which increased manoeuvrability is obtained. The
opposite lock power transmitter (50) can be used on vehicles having an active
tilting system with drive means, such as, for example, hydraulic tilting
cylinders (9, 9'), which are controlled by a sensor depending on the radius

9') can optionally serve as a control signal for the opposite lock power
transmitter (50). As a result of the active application of opposite lock, the
tilting cylinders (9, 9') can be of relatively small construction. |

The invention relates to a vehicle (1) provided with
a frame (2) having a front frame part (3) and a rear frame part (4) which can
tilt with respect to one another. The vehicle (1) comprises three or more
wheels (7, 7', 13), it being possible to rotate the front wheel (13) with
respect to the steering column (18). In this case, a sensor (24) determines
the angle of rotation between the front wheel (13) and the steering column
(18) and, as a function of this angle of rotation, actuates the tilting means
(9, 9') of the vehicle. As a result of the consequent tilting of the front
frame part (3) and as a consequence of the speed at which the vehicle (1) is
travelling, the front wheel (13) and the tilting angle will automatically
adopt the correct level for allowing the vehicle (1) to travel through the
bend in a stable manner at the given speed.; Controlling the tilt via the
difference in angular rotation between the steering column (18), which is
flexibly connected to the front wheel (13), and the front wheel (13), it is
possible to control the tilt in a simple and robust manner. |

The invention relates to a vehicle, equipped with a
carrying section with a front wheel and a driving section , that freely turns
around a lengthwise axis line in a loaded state from the driver's section
situated above the centre of gravity of it, as a result of which the driver
section will spontaneously assume a slope depending on the turning radius and
speed of the vehicle when executing a turn. The vehicle is consequently
extremely stable. In addition the driver's section can contain a wheel that
can be steered and the axis over a contact point of this wheel is situated
with a base, which further increases the turning stability of the vehicle in
bends. |

PURPOSE:To provide restoring force with a large
oscillating angle in vertical or horizontal direction and no movement of an
oscillating fulcrum regardless of a small design of a motor tricycle by
making the relative oscillating amounts of a shaft to the outermost
cylindrical body equal to the sum of all the respective relative oscillating
amounts of the innermost cylindrical body and mutually adjoining cylindrical
bodies. CONSTITUTION:The relative oscillating amount of a shaft 20 to the
outermost cylindrical body 14 becomes the total sum of the relative
oscillating amount of the outermost cylindrical body 14 to a middle
cylindrical body 16, the relative oscillating amount of the middle
cylindrical body 16 to the innermost cylindrical body 18 and the relative
oscillating amount of the innermost cylindrical body 18 to the shaft 20.; As
a result, the shaft 20 and the outermost cylindrical body 14 can be
relatively oscillated against the elastic force of rubbers 22, 24, 26 within
the maximum oscillating range of 30 + 30 + 30 = 90 degree. Moreover, elastic
energy is accumulated by elastic deformation of rubbers 22, 24, 26 due to
relative oscillation, and after rear wheels 9, 9 rides across roughness,
restoring force is generated by the elastic energy. It is thus possible to
provide the optimum restoring force by selecting the material of rubbers 22,
24, 26 and so forth. |

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 parking locking system for an articulated or
swing-type tricycle. A parking lever mounted to the handlebars of the steerable
wheel actuates a cable and a rod. The rod engages a spring loaded slideable
pin member into a hole in a plate fixed to the front frame of the steerable
wheel. If the pin is not aligned with one of the holes in the plate, the
spring will deform and the pin will slide relative to the rod. Upon further
rotation of the front handlebars to a position where the pin member is
aligned with a hole, the compression in the spring will cause the pin to
interengage with the fixed plate thus locking the front steering wheel. The
actuation of the cable interengages locking arms with a plate attached to the
front of the swing shaft and with a parking gear in the drive train,
respectively.; A spring-loaded lever resisting interengagement of the locking
arms is used to create tension in the cable and retract the locking arms when
the parking lever is deactivated. |

A rear-wheel suspension device on a tricycle vehicle
having front and rear vehicle portions interconnected by a rolling joint
having a sleeve bearing. To provide increased stability between a pair of
rear wheels of the tricycle vehicle, a casing of the rolling joint is
pivotably mounted on a frame of the front vehicle portion for pivotable
movement. The rolling joint has a spindle connected in a fixed positional
relationship relative to axles of the rear wheels. A shock absorber is
interposed between the frame and the casing. To increase damping and vibration-isolating
ability, the casing is pivotably connected to the frame by a link, and the
shock absorber is oriented so as to be substantially perpendicular to a
straight line passing through an axis of the rear-wheel axles when they are
loaded and a pivot point at which the link is pivotably connected to the
casing.; The link and the shock absorber have respective longitudinal axes
extending substantially parallel to each other, and an engine is oriented
such that major vibrations thereof are produced in a direction substantially
at a right angle to the aforesaid longitudinal axes. |

hangingly supports a swing joint in three-wheeled motor vehicle having front
body laterally swingable relative to a rear body. The position adjusting
means includes a pair of flexible stops, one being positioned behind one end
of a sleeve member which supports a pair of link members, and the other being
positioned in front of the sleeve member. These stops are mounted onto a pair
of frame members positioned in the front body and extending in parallel along
travel direction of the vehicle, or mounted onto one of said frame members so
as to position at least one end of said sleeve between the stops. The link
members each have an upper end integrally connected to a supporting member
and a stop is secured to the lower surface of each supporting member.; The supporting
members extend in horizontal plane and opposite direction relative to the
sleeve along travel direction of the vehicle. The sleeve supports the pair of
link members and is concentrically supported by a pivotal shaft through
rubber bushes. The both ends of the pivotal shaft is secured by a pair of
brackets mounted on the pair of frame members. Upon placement of the stops
onto the frame members, the link members provide vertical orientation. |

|
The device in accordance with the invention operates
and controls the tilt of a body of a vehicle and is operated by a driving shaft
driven in rotation by movement of the vehicle. A rocking mechanism that is
capable of being driven in two opposite directions by the driving shaft
employs two disengageable coupling assemblies to operate rocking of the body,
each in one direction. Progressive engagement of one or other of the coupling
assemblies is operated directly by a pendular mass. Deviation of the latter
to one side or the other of a plane passing through its axis of oscillation
and parallel with the median plane of the body, causes progressive engagement
of that one of the two coupling assemblies.; This causes rocking of the body
in a direction which enables the median plane of the latter to be brought
back into the direction of the apparent vertical passing through the axis of
oscillation and the center of gravity of the pendular mass. |
