HISTORY
Pull rods were first brought to Formula 1 by
Gordon Murray with Brabham in the 70s.
Now all formula one teams make use of
the push rods, as pull rods are quite hard
to implement in ahigh nosed car.
Minardi and Arrows used pull rods with low
noses to lower the centre of gravity. These
two teams are a last two to use this
concept.
INTRODUCTION
Push-rod as the name suggests the
rod push up to therocker .
In pull-rod the rod is pull down to the
rocker .
PULL-ROD
Pull rod set up has a strut from the
outer end of the upper wishbones
that runs diagonally to the lower
edge of thechassis .
PUSH- ROD
A push rod is the opposite; the strut
runs from the lower wish bone to the
upper edge of thechassis.

ROCKERS
Transfers
the
vertical
reciprocating
movement of the push/pullrod into
rotational movement at the torsion bar.
TORSION BAR
The torsion bar acts as
the spring that absorbs
shock loads from the
suspension movement.
Its strength is controlled
by the alloy mixture, its
thickness and the length.
HEAVE SPRING
The heave spring controls how stiff the car
is when both sides of the cars suspension
are compressed together for example
under braking, or acceleration, or over a
hefty bump.
TRACK ROD
The track rods controls the steering
of the wheel hubs.
They are normally attached to the
front of the wheel hub.
WORKING OF
PUSH BAR
SUSPENSION
ADVANTAGES
Absence
of
bulky
suspension system.
Smooth flow of air
through the sides of
the vehicle.
making it turbulent
hence
the
aerodynamics of the
vehicle is undisturbed.
decreases air drag.
you can modify motion
ratio/spring ratio with
the rocker.
DISADVANTAGES
Higher CG (centre of gravity)
Access to the dampers/springs can
be more difficult.
Another disadvantage is increased
friction caused by the increased
amount of bearings under high loads.
APPLICATION
Ferrari F300

Mercedes F-1

CONCLUSION
A pushrod-type inboard suspension on a
lightweight road race car.
The pushrod are necessarily heavier than
in pull-rod arrangement, the mass of the
spring/damper units is located higher
up,and the loads on the structure are more
focussed and complex than with some
alternative arrangements.
Nevertheless this scheme is currently used
by virtually all formula and indy cars and
many other racers- simply because the
spring/damper units are easily accessible
for adjustments.
