1. SUSPENSION
The suspension is the device to connect the axle and vehicle. It absorbs the vibrations and
impacts from road surface, which enhances the comforts, driving force, braking force and
drivability.

2. FRONT SUSPENSION (DOUBLE WISHBONE)


Double wishbone suspension is an independent suspension design using two (occasionally parallel)
wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the
chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to
control vertical movement. Double wishbone designs allow the engineer to carefully control the
motion of the wheel throughout suspension travel, controlling such parameters as camber angle,
caster angle, toe pattern, roll center height, scrub radius, scuff and more.

Lower arm Upper arm Shock absorber Stabilizer

ඖ Advantage
1. The advantage of a double wishbone suspension is that it is fairly easy to work out the effect
of moving each joint, so the kinematics of the suspension can be tuned easily and wheel
motion can be optimized.
2. It is also easy to work out the loads that different parts will be subjected to which allows more
optimized lightweight parts to be designed.
3. They also provide increasing negative camber gain all the way to full jounce travel unlike the
MacPherson strut which provides negative camber gain only at the beginning of jounce travel
and then reverses into positive camber gain at high jounce amounts.
ඖ Disadvantage

1. The disadvantage is that it is slightly more complex than other systems like a MacPherson strut.
2. Due to the increased number of components within the suspension setup it takes much longer to
service and is heavier than an equivalent MacPherson design.

3. REAR SUSPENSION (MULTI LINK TYPE)


Multi-link (5-Link) type suspension is the independent suspension. It provides good ride comfort
and drivability by reducing the coil spring weight. Also, it increases the space for passenger
compartment by lowering the floor. This type of suspension consists of multiple links such as coil
spring, shock absorber, upper and lower arms, lateral rod and stabilizer bar.

4. WHEEL ALIGNMENT
The front wheels have specific angle to allow control of the steering wheel with less effort, ensure
driving stability, improve steering wheel restoration and steering performance, and minimize the
tires wear.

1) Toe-in
The difference of measured distances between the front ends of the tires (A) and the rear ends of
the tires (B) along the same axle when viewed the wheels from the top

Front

Toe-in YG·GYG””GOW¥[G””P

ඖ When viewed from the top, the distance between the tire centers is smaller in the front than in
the rear.

- Side slip protection


- Parallel front wheels rotation (straight ahead driving is ensured by toe-in to prevent the wheels
from tilting outwards by the camber while driving)
- Prevention of uneven (outward) tire wear
- Prevention of toe-out from wearing of steering linkage
4411-01 ࣩ࣭࣯࣬ࣴ

2) Camber
The angle between the center line of the tire and the vertical line when viewed from the front of
the vehicle

LH TWUX`¶G·GWUY\¶G
Camber
RH TWUY`¶G·GWUY\¶G

ඖ Positive camber: Top of the tire is tilted outward


Advantages: - The axle is not bent when it is loaded.
- The force required to operate the steering wheel is reduced due to
smaller contact area (or load area) of the tire.
- Restoring force of the steering wheel is gained (when turning the
steering wheel, the tire circles and the force to lift the frame is applied.
In this case, the shock absorber contracts and the restoration force is
applied to the steering wheel.)
Disadvantages: - Cornering force decreases as the positive camber increases when
the vehicle makes turn.
- The hub bearing is worn unevenly if camber is excessive.

ඖ Zero camber: When the tire center line is perpendicular to the ground level

ඖ Negative camber
Advantages: - Better traction force due to wide load area (applicable for off-road vehicle)
- Better corner driving when the vehicle makes turn as the cornering force
Disadvantages: increases (applicable for high-speed F1 vehicle)
- he axle is easy to be bent or deviated in the negative camber than in
the positive camber when load is applied on the axle.
- Difficult to control due to wide load area.
ࣰࣩ࣭࣬ࣴ

3) Caster
The angle between the vertical line and king pin, which fixes the steering knuckle and front axle,
(steering column which connects the top and bottom ball joints in the independent axle type)
when viewed the tires from the side.

LH [U[¶G·GWU[¶G
Caster
RH [U\¶G·GWU[¶G

ඖ Caster: With considering the height difference between the wheel centers of the front and rear
wheels. (Under standard condition that the vehicle is on a level ground)

ඖ Positive caster:Top of the king pin is tilted backward from the vertical line of the wheel center
when viewed the tires from the side
Advantages: - Directional force to go straight (following control)
- Restoring force of the wheel (restored to the straight ahead direction)
- Prevention of wheel shimmy (wheels wobble left and right)

ඖ Negative caster: Top of the king pin is tilted forward from the vertical line of the wheel center
when viewed the tires from the side
Advantages: - Smaller turning radius
Disadvantages: - Impact from the road is transferred to the steering wheel (steering wheel
turns)
- Poor straightness

4) Operating Process
The telescopic shock absorber consists of a tube with piston and rod and a cylinder tube. The
piston has an orifice and valve and the cylinder is filled with oil. The double action cylindrical type
shock absorber restrains the vibrations by using oil resistance. This provides better drivability even
though the structure is complicated. This vehicle uses the gas shock absorber.

1) Overview
If the spring with lower spring constant is applied on the vehicle in order to increase the "ride
comforts", the vehicle's slope increases on turning due to the centrifugal force. Because its trend
increases for the independent suspension system, the stabilizer bar should be applied to the
system in order to make a balance the vehicle. The stabilizer bar is a certain type of torsion bar. Its
both ends are connected to the control arm and the its center area is mounted to the body frame.
It is not activated when both wheels are moving up or down simultaneously. However, it minimizes
the vehicle's slope when each wheel moves up or down independently.

1) Overview
The coil spring is made by winding solid steel rod to form the coil shape. Its energy absorption
rate per weight is higher than that of the leaf spring and it allows to absorb small vibration properly
resulted in keeping the ride comforts. Therefore, it's difficult to make an effect on vibration
damping because there is not any friction between coils.
