4. IWE LOCKING HUB SYSTEM
1) Overview
The vacuum locking hub uses the IWE (Integrated Wheel End) system, and in this system, the
vacuum is generated only within the hub actuator.
It is structured to transmit power to the front section after the actuator hub is engaged following
the release of vacuum from the drive shaft end gear and the hub end gear.

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.
