|
An apparatus for shifting the center of gravity for use
in a vehicle having three wheels or more, and a lozenge- shaped automobile
having the same are provided. The apparatus comprises a stationary chassis, a
movable chassis, and a gear device for moving the movable chassis relative to
the stationary chassis. The stationary chassis is disposed perpendicular to
the forward direction of the automobile, and has a stationary rail. The
stationary rail is formed in a circular shape having, as the origin, a point
on the line projected on the ground from the longitudinal center line of the
car body parallel to the forward direction of the automobile. The movable
chassis is disposed parallelto the forward direction of the automobile, and
has a moving rail engaged with the stationary rail so as to move therealong.
The moving rail moves to the left/right relative to the forward direction
along the stationary rail. A moving gear is installed on the movable chassis
parallel to the moving rail. A rotating gear is installed on the stationary
chassis so as to be engaged with the moving gear. A ball screw device is
installed so as to be engaged with the rotating gear. The lozenge- shaped
automobile having the above construction includes a steering unit for
simultaneously steering three front wheels in the forward direction of the
automobile. |

extended by a bearing (9). There are two wheels (2a,b) fixed to a drive shaft
(52) and a swinging cross member (3) which is controlled by a cable (26)
extending from the front fork pivot of the scooter. There is an arm (6a) with

A side car for a motorcycle, wherein the side car box overlies the
side car wheel directly thereabove. The lateral coupler between the side car
and the motorcycle biases the side car wheel to incline interiorly of a
curve, together with the motorcycle wheels, upon the moving vehicle taking a
curve on a road. The side-car frame and box axially roll with the wheel,
whereby the side-car center of gravity remains continuously within the plane
of its wheel. As the motorcycle wheels progressively axially roll, their
angular value relative to the vertical plane will increase relative to a
second angular value corresponding to the roll of the side-car wheel relative
to the vertical plane. |

PURPOSE:To permit the self erection on stop and
provide the steering feeling which is nearly same to that of a motorcycle.
CONSTITUTION:A rear fork 9 for supporting left and right rear wheels Wr for a
car body frame 1 which supports front wheels Wf is pivotally supported in
vertically swingable manner through a pivot 10, and the car body is erected
by the front and rear wheels Wf and Wr on stopping the left and right rear
wheels Wr are applied with the plus camber, and the distance between the
grounded parts of both the rear wheels Wr is set small, and then the bank of
the car body is facilitated, and the turning performance is improved.; Both
the rear wheels Wr can be steered in the reverse phase to the steering
direction of the front wheels Wf by the lateral force applied from a road
surface by the action of the plus trail T, and can be steered positively to
the reverse phase or same phase for the front wheels Wf by an actuator using
a motor as drive source. |

PURPOSE:To take a bank posture in a curve running
and to improve the cornering performance by providing a pair of wheel members
combined rotatable at both ends of a lateral member and holding the left and the
right wheels at the free ends, a connecting member to connect the both wheel
members and a car body, and the like. CONSTITUTION:In a rolling mechanism 30
suitable to a motorbike of the type furnishing one front wheel and two rear
wheels and having the car body separated into the front part and the rear
part, the central part of a lateral member 32 is connected to a part of the
front part 10 of the car body by a rolling shaft 28 to roll freely, and the
upper ends of a pair of V-shaped left and right wheel members 40 are pivoted
42 to both ends of the lateral member 32.; And at the middle parts of both
wheel members 40, one ends of connecting members 44 are pivoted 46, while the
other ends of the connecting members 44 are connected rotatable by a shaft 48,
and the chassis of the rear wheels 22 are held by the lower ends of both
wheel members 40 separately. And the form of the car body, the arrangement of
the driver seat, and the like are determined to position the center of
gravity of the car body lower than the shaft 48. |

According to the present invention, with a
motorcycle in which only the front frame banks and the main frame is
prevented from banking, the connecting shaft, between the front frame and the
main frame, is arranged and provided under a line connecting centers of the
front and rear wheels so that a rotating center of the front frame for
banking may be located in a lower position to lower the center of gravity of
the vehicle. |

A motorcycle has a frame assembly including a main
frame (5) supporting front (1) and rear (3) wheels on a central line (C0)
thereof, a connecting means (6) mounted on the main frame (5) between the
front (1) and rear (3) wheels, and a subframe (7) mounted on the connecting
means (6) and being capable of banking laterally about the connecting means
(6). At least one of the front (1) and rear (3) wheels is a drive wheel, at
least the drive wheel (3) being capable of preventing the main frame (5) from
banking laterally. Centrifugal forces generated upon cornering are
counterbalanced by centripetal forces produced when only the subframe (7)
banks laterally, and the drive wheel (3) supported on the main frame (5)
which does not bank has an increased road gripping force. Thus,
high-speed cornering is made possbile. |

A three-wheeled vehicle has a pair of right and left
wheels provided at either end of the vehicle body and a single wheel provided
at the other end of the vehicle body. The pair of wheels are spaced from each
other laterally with respect to the vehicle body. The three-wheeled vehicle
is further provided with a steering mechanism for steering the pair of
wheels, and a mechanism which cooperates with the steering mechanism for
displacing the single wheel substantially laterally with respect to the
vehicle body and in the direction opposite to the direction of turning of the
vehicle caused by the steering operation of the steering mechanism. In
another embodiment the single wheel is also pivoted in a direction opposite
the turning of the pair of wheels. |
