Motorcycle Mono Shock Front Steering
Field of invention:
The invention relates to the field of motorcycle front steering and
suspension mechanism.
Background of the invention:
Motorcycles have been a part of our lives since.a long time and the basic
design and structure have also remained almost the same. The front
steering is one of those parts of the. motorcycle whose basic design has
not been changed much. Two telescopic fork arms with two separate
suspension cylinders attached to the fork head is what have been followed
till now. With this invention, the front steering and suspension has been
redesigned altogether. The single suspension has not been used ever for
the front suspension and this is the main component around which the
whole steering mechanism of this invention is designed. This design gives
the motorcycle a unique look and also the rider, a different and an
unmatched steering and handling experience.
Description:
The following specification particularly describes the invention and the
manner in which it is to be performed.
The motorcycle steering and suspension mechanism comprises of a front
fork attached with the frame and not the handlebar with an acute fork
angle.
The front fork of the motorcycle is attached with the frame enabled to
rotate freely along the axis where it is attached and can also rotate on the
axis of the fork tube.
A head tube is placed behind the joint of the front fork to allow the fork to
rotate along its own axis (axis of the fork tube), which is essential for the
steering of the motorcycle.
A suspension spring is attached with the head tube at one end and with
the frame, in front of the sprocket, on the other end with an angle of
around 45 degrees.
Handlebar is attached to the main sprocket, making an angle of about 30
degrees with the ground.
The sprocket gear is wrapped around with a heavy duty chain whose ends
are connected with the front fork side arms between the head tube and the
point where the fork is joined with the frame.
Two tensioners are placed in between the chain gap below the sprocket to
constantly maintain the tension in the chain when the suspension is under
load.
Brief description of the drawings:

appended claims. The invention, together with further objects and
advantages thereof, may best be understood by reference to the following
description taken in conjunction with the accompanying drawings in which:

Detailed description of the illustrated embodiments:
In figurel, the steering mechanism of the motorcycle is shown from the
side where the handlebar (1) is connected to a sprocket (4) wrapped
around with a chain (3), which rotates the front fork side arms (10) and
hence the front fork (6). As it can be seen from this perspective, the front
fork (6) of the motorcycle is not directly attached with the handlebar and at
an angle of around 30 degrees to the ground. The front suspension (5) is
attached with the frame (11) at one end and with the fork head (7) at the
other. The fork head (7) can be seen just behind the front for neck.
In figure2, the steering mechanism is shown from the top. The wheel (2)
can be seen at the top of the figure fixed between the front fork legs (9),
which is attached with the frame (11) of the motorcycle at the other end,
down below in the figure. From this view it can be seen, that the handlebar
(1) is in its centred position and the front suspension (5) is just above the
fork tube (8).
In figure3, the front view of the steering mechanism is shown where the
front wheel can be seen, which is in between the front fork legs and has
the sprocket (4) chain (3) set behind it. The handlebar (1) is in its centred
position.
In figure4, the view is same as in figure3, but here the handlebar (1) has
been turned to show the bending motion of the front wheel (2). Here the
handlebar (1) is turned towards the right hand side of the motorcycle (left
from the front view), therefore the front wheel (2) has also bent towards
the right side. A tensioner (13) can also be seen under the chain behind
the wheel.
In figure5, the rear view of the invention is shown where the handlebar (1)
is attached with the sprocket (4) which rotates at the same axis of rotation
as of the handlebar. The chain (3) runs around the sprocket and is
attached with the front fork side arms (10) at its ends. Its tension is
maintained by the tensioner (13) under it. The front suspension (5) can
also be seen from underneath the chain (3).
In figure6, the rear view of the invention is shown where the handlebar (1)
is turned towards the right side, due to which the sprocket (4), has turned
clockwise. Due to this rotation, the chain (3) has also moved and now is
more towards the right side. As a result the front fork (6) has rotated along
its axis and the wheel (2) has bended towards right.
In figure7, all the main components have shown in an ungrouped manner.
Every part is placed near its adjoining part.

Claims:
I claim,
1. The front fork of the said motorcycle's front steering is no attached
with the handlebar directly but attached with the frame of the said
motorcycle.
2. The said front fork is able to rotate about the central axis of the fork
tube of the said front fork, attached to the said frame of the said
motorcycle.
3. The said front wheel bends more along with turning sidewise
towards the side it is steered, instead of conventional turning.
4. The handle bar of the said motorcycle is connected to the chain
sprocket assembly which transfers the energy to the said front fork
by pulling and pushing the front fork's side arms.
5. Two tensioners are placed below the said sprocket to keep the
chain under tension when the suspension is under load or the
suspension spring is compressed.
6. The said front fork has two arms perpendicular to the said fork tube
of the said fork and they are at 180 degrees to each other,
connected to the said chain at their respective ends.
7. The fork head of the said front fork is situated around the said fork
tube and just behind the said front fork joint which holds the said
front fork in its position and is also a mount for the front mono
suspension of the said motorcycle.
8. The said front mono suspension is connected to the said frame of
the said motorcycle in front of the said chain sprocket assembly.
9. The said motorcycle has only one single spring suspension
attached with the said fork head and the said frame of the.said
motorcycle.
