FIELD OF INVENTION
The present invention is related to suspension system of automobile, especially for bike front
suspension with the two units of separate suspension.
BACKGROUND OF THE INVENTION
Suspension systems of prior automotive like bike front suspension basically use telescopic type which
is conne$§(J<©n SSfrie angle from vertical. This type of arrangement of suspension can absorb shock
efficiently if shock isdmes in same line of suspension.
• • <*
This typQ: of suspension arrangement do not work properly when load applied on vehicle because
gravitational force works on load directly downwards and suspension is connected at some angle.
This type of suspension arrangement has to move more than the size of bumps and holes in order to
absorb the shock produced by these holes and bumps.
SUMMRY OF THE INVENTION
Present invention gives significantly good shock absorption capacity and works efficiently in any type
of shock and in any condition.
Bi suspension arrangement has two units connected with each other, one unit connected vertically
with wheel and second unit connected at some angle with first unit, the top end of the second unit
connected with vehicle and bottom end of first unit connected with wheel. First unit and second unit
are separately a complete suspension itself. For the arrangement of bi suspension any two
suspension can be used for first and second unit but for first unit centre disc bi direction suspension
(Indian patent no 446/del/2015) is better because of their connecting property and movement.
Working of suspension depends on many situation like road condition (bumps and holes), direction of
force, speed of vehicle, time duration, position of the object, and even depends on size of shock
producing object. Bi suspension arrangement gives good control and good shock absorption capacity
in all these condition.
WORKING OF THE BI SUSPENSION ARRANGEMENT
On the basis of bumps and holes on road, force gets exerted on suspension in two manners. During
bumps suspension gets compressed and during holes suspension gets released: These bumps and
holes create two forces one due to the motion of vehicle and one due to height of bumps and in case
of holes the force act in opposite direction of the force as work in case of bump, when force strike to
BI suspension arrangement both first unit and second unit works, it absorb shock efficiently between
both line of direction of suspension of first unit and second unit, if produced force direction is more
closer to first unit then first unit move more and if line of force is more closer to second unit the
second unit move more. Due to the combined movement of both unit bi suspension arrangement has
to move less than the size of shock producing object in order to absorb shock and provide more
control over vehicle.
In case of holes in road due to the combined expansion of both units it has to expand less than the
size of hole in order to touch the ground and due to combined expansion property it also reduces
projectile time in deep hole.
Speed is also a dominating factor to decide the working of suspension, on high speed suspension
takes longer time to touch the ground in holes because vehicle tries to maintain their position in line of
motion but bi suspension arrangement suspension touches ground faster because of its combine
