TITLE- CENTRE DISC BI DIRECTION SUSPENSION
DESCRIPTION
statement
centre disc bi direction suspension is specially designed to absorb more
shock and move in bi direction. Normal suspension moves in only one
direction in no load condition, it creates either compression or expansion but
bi direction suspension can move in both directions at the same time in no
load condition. This suspension include shaft connected with disc placed
inside a cylinder.
SUMMRY
TYPE-1
Disc-shaft attachment placed inside of cylinder and both sides of the disc fitted
with two spring and filled with hydraulic fluid, disc has two one way valves one
valve facing up side another down side this valve gives the way to hydraulic
fluid to move high pressure region to low pressure region, opening of valve
depends on the strength of force of hydraulic fluid generated during shock if
strength of force is large valve would open more. Movement of disc decide
compression chamber and expansion chamber if disc moves up and relatively
cylinder moves down then the chamber upside of disc would be compression
chamber and downside of the disc would be expansion chamber so in this
condition hydraulic fluid moves from upside chamber to downside chamber:
valve is fitted inside the disc so it is also moveable relatively to the cylinder,
disc having two oil seal at its circumference to prevent the unwanted leakage
of fluid between two chambers, oil seal and air seal also present at the both
ends of cylinder. Both sides of the disc having spring and hydraulic fluid
which provide large resistance in frequent motion (up-down, down-up) of disc
relative to cylinder and reduce damping.
TYPE-2
It is a same as above only the change is there is no valve present inside disc
both sides of disc have spring and compressed air and air seal at the
circumference of disc also at the both ends of the cylinder. Movement of disc
creates compression chamber and expansion chamber. In compression
chamber spring and gas get compressed and vice versa in opposite chamber.
TYPE3
In third type cylinder is made up of copper and aluminium, shaft fitted with
powerful magnet on both sides of disc and both ends of cylinder also fitted
with powerful magnet facing the same pole disc having. Due to same pole
facing repulsion generated on disc from the both ends of cylinder due to this
disc adjusts itself in place where repulsion from both sides is equal. During the
- time of bumps disc and cylinder move respectively which change the magnetic
field density inside cylinder which produces the eddy current in cylinder which
also opposes the motion of disc and cylinder.
TYPE-4
In the same design highly vacuum is created on the both sides of disc so that
pulling force work on disc from the both ends of cylinder which holds the disc
at the place where pulling force is equal from both sides. Both end of cylinder
fitted with air seal and disc also fitted with air seal at circumference to prevent
the air rushing inside the cylinder from atmosphere.

DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO
DRAWING
Reference is made to fig-I in which a shaft generally indicates as 1 include
cylinder 2 and a connecting hook 3.
Reference is now made to fig-2 in which cylinder 5 includes with shaft 4
fitted with disc 18 and two oil seal 12,13. Disc can open in two part from
centre 14. Space upside of the disc 8,11 and space downside of the disc 9,10
filled with hydraulic fluid and fitted with two spring 7 upside of the disc and
spring 15 downside of the disc. If disc 18 moves upside and cylinder 5
moves down relatively upper chamber 8,11 have more compression and
considered as compression chamber 8,11 and other chamber considered as
expansion chamber 9,10 in this condition fluid moves from the compression
chamber 8,11 to expansion chamber 9,lO. Both end of cylinder fitted with oil
seal 17,18. Slight curve 6 made on disc and in cylinder on inside edge 19,20
- to concentrate fluid force in middle.
Reference is now made to fig4 in this figure everything is same only edge
of cylinder is fitted with air seal 21,25 and disc 22 have no valve only having
two air seal 23,24. Both the chamber 26,27 filled with compressed air, there is
no exchange of compressed air from compression chamber to expansion
chamber. It can also fitted with spring in chamber around shaft.
Reference is now made to fig-4 shaft 28 including cylinder 29 made up of
specially copper or aluminium and inside up and inside down of cylinder 29
fitted with powerful magnet 30,33 and disc is also fitted with two powerful
magnet 31,32 upside and downside of the disc. same pole of magnet (N,N)
and(S,S) faces each other to create repulsion force. Space 34,35 in which
disc can move.
Reference is now again made to fig3 every thing is same as fig-3
arrangement only the change here is, vacuum is created in chamber 26,27 so
that if disc 22 moves in either direction the opposite chamber provide
resistance. It can also fitted with spring upside and downside of disc around
shaft.
Reference is now made to fig-5 disc is fitted with valve assembly for flow of
hydraulic fluid from pressure chamber to low pressure chamber, first a valve
guide 39 is fitted with disc, valve guide 39 is of two layer inside space is for
valve 43 and outside have vacant space 37 with two hole 42,47 which provide
fluid to enter in vacant space 37 to flow from high pressure to low pressure.
Valve is locked with valve lock 46 and valve lock 46 is fitted with rubber band
45 on it to prevent fluid leakage when valve rest on it. On the upper side of the
valve 43 one spring 36 fitted with screw 38 by this screw, compression
strength of spring 36 can be changed which decide the strength of force
required to open the valve 43. When valve 43 pushes up by fluid pressure
valve 43 move in space 44 and both hole 42,47 get open liquid rushes through
guide space 37 in expansion chamber space 44 also determine the size of
hole 42,47 if valve 43 move more in space 44 provided the hole 42,47 will
open more Disc have space for oil seal 40,41 on its circumference.

CLAIM
Centre disc bi direction suspension claim;
1- It can absorb more shock.
2- There is no end to end movement.
3- It can move in bi direction even in no load condition.
- 4- It reduce damping.
5- In single shaft more than one suspension can be arranged.
6- Motion occurs between shaft and cylinder.
7- This suspension can be connected in series and parallel.
8- Valve is arranged inside the disc.
9- Valve also moveable.
10- Arrangement of valve.
11 - All four type arrangement of suspension
12- Disc can be fitted in the end of shaft and this
attachment placed inside the cylinder in same way that it
creates two partition inside cylinder, in this condition end to
end motion is present
13- Spring can also be arranged outside of the cylinder, on
the top side of cylinder and bottom side of cylinder.
14- Valve guide is double layered and having space
between layers for fluid movement.
15- It increase contact time between road and tyre during
