1) Front Suspension (Double Wishbone)
Suspension is the term given to the system of springs, shock absorbers and linkages that connects a
vehicle to its wheels and allows relative motion between the two. Suspension systems serve a dual
purpose - contributing to the vehicle's road-holding/handling and braking for good active safety and
driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road
noise, bumps, and vibrations, etc. These goals are generally at odds, so the tuning of suspensions
involves finding the right compromise. It is important for the suspension to keep the road wheel in contac
t
with the road surface as much as possible, because all the forces acting on the vehicle do so through
the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage
from damage and wear.
2) Rear Suspension (Multi Link Type)
1. OVERVIEW
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.
The multi-link type is used for the rear
suspension to distribute the internal force (load)
applied to the link while driving. Also, the change
in camber or toe and shock load from the road
has been minimized by optimizing the link
arrangement.

Upper Arm
The upper arm is mounted to the frame
and the knuckle and it relieves the load
delivered from the tire to the knuckle.
This enables to absorb the various
impacts according to the load shapes
and to ensure the drivability.
Lower Arm
Knuckle
There are two types of knuckle (4WD,
2WD)
Cam bolt
1) Front Suspension (Double Wishbone)
The lower arm is mounted to the knuckle, the
shock absorber and the lower arm assembly. It
relieves the load delivered from the tire to the
knuckle. This enables to absorb the various
impacts according to the load shapes and to
ensure the drivability.

Shock Absorber Assembly
Stabilizer Bar Assembly
The stabilizer bar is intended to force each side of the vehicle to lower, or rise, to similar heights, to
reduce the sideways tilting (roll) of the vehicle on curves, sharp corners, or large bumps. The basic
function is to force the opposite wheel's shock absorber, spring or suspension rod to lower, or rise, to a
similar level as the other wheel. In a fast turn, a vehicle tends to drop closer onto the outer wheels, and
the sway bar will soon force the opposite wheel to also get closer to the vehicle. As a result, the vehicle
tends to "hug" the road, closer in a fast turn, where all wheels are closer to the body. After the fast turn,
then the downward pressure is reduced, and the paired wheels can return to their normal height against
the vehicle, kept at similar levels by the connecting stabilizer bar.

Coil spring -
The shock absorber assembly reduces the effect of traveling over
rough ground, leading to improved ride quality and increases in
comfort. While shock absorber serves the purpose of limiting
excessive suspension movement, their intended sole purpose is to
dampen spring oscillations. The shock absorber in this vehicle uses
the gas to absorb excess energy from the spring.
Shock absorber -
Keep the clearance to drive shaft.
To prevent the transverse force to shock absorber, the upper
center line and the lower center line of shock absorber are
placed on same line. 1.

3. WHEEL ALIGNMENT
Wheel alignment (adjustment of Camber, Caster and Toe) is part of standard automobile maintenance
that consists of adjusting the angles of the wheels so that they are set to the specification. The purpose
of these adjustments is to reduce tire wear, and to ensure that vehicle travel is straight and true (without
"pulling" to one side). Alignment angles can also be altered beyond the specifications to obtain a specific
handling characteristic.
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 -
-
-
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.
Toe-inFront0.˚±0.10˚
Rear0.48˚±0.15˚
Necessity for Wheel Alignment ▶
Wheel alignment consists of adjusting the angles of the wheels so that they are perpendicular to the
ground and parallel to each other. The purpose of these adjustments is maximum tire life and a vehicle
that tracks straight and true when driving along a straight and level road.
The symptoms of a vehicle that is out of alignment are:
Uneven or rapid tire wear
Pulling or drifting away from a straight line
Wandering on a straight level road
Spokes of the steering wheel off to one side while driving on a straight and level road.

2) Camber
The angle between the center line of the tire and the vertical line when viewed from the front of the
vehicle
CamberFront-0.12˚±0.50˚
Rear-1.20˚±0.50˚
Zero camber: When the tire center line is perpendicular to the ground level ▶
Disadvantages:The 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. -
- 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 -
- Negative camber ▶Disadvantages:Cornering force decreases as the positive camber increases when the vehicle
makes turn.
The hub bearing is worn unevenly if camber is excessive. -
- 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.) -
-
- Positive camber: Top of the tire is tilted outward ▶

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.
CasterFront4.80˚±0.50˚
Rear -
Disadvantages:Impact from the road is transferred to the steering wheel (steering wheel turns)
Poor straightness -
- 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) -
-
-
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 Positive 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) Caster: ▶
Advantages:Smaller turning radius -Top of the king pin is tilted backward from the vertical line of the wheel center
when viewed the tires from the side
