DOOR'S SYSTEM
INTRODUCTION - IRIZAR'S I6 DOOR SYSTEM
The vehicle's door system is designed to open and close during normal and emergency operation. As being
an electro-pneumatic system, it possess a sensibilization system, which is capable of avoiding any accident during
the process of closure and opening.
The pneumatic system has a lubrication and protection system with a separation valve between the chassis
and body. This valve can be used for leaking diagnoses or air removal during the door's system maintenance
process.
The i6 door's system has the structure protected by aluminium plates. Isolating agents are also applied in
the interior, to provide thermal and acoustic isolation.
The sealing system is composed by a solid rubber, with no junctions on the edges or over the doorstop.

DOOR'S SENSIBILIZATION SYSTEM
The door's sensibilization system operates during the opening and closure of the door. During the closure
the system operates when the electric system possess the +30 line, in other words, the main switch must be on. To
opening, the system operates permanently, even when the +30 line isn't working, disconnected main switch.
During the closure process, the micro-switches system acts under the door's solenoid, reverting the
movement, in case of any obstacle interrupt the door's movement. During the opening process, the door has its
movement protected, avoiding any collision with adjacents components, such as compartment cover.

Picture 1 - Sensibilization during closure
from opening
It is possible to adjust the performance of the sensibilization system by adjusting the aluminium cam. This
cam turns with the door's movement, providing the protection during the closure.
There are two micro-switches connected, on vertical and the other horizontal. When the cam reaches the horizontal
micro-switch (at the end of the door's course), the cam disables the vertical micro-switch, canceling the
sensibilization. In case of an obstacle during the closure, the cam won't reach the horizontal micro-switch. The force
imposition against the closure makes the door to initiate a vertical movement. The movement elevates the plastic
part, in shape of half moon, activating the micro-switch that sends an electric signal to the door's valve so the
movement of closure is reversed, therefore openning the door.

DOOR SYSTEM ADJUSTMENT
The vehicle's door must be considered misfit when:

Presents excessive noise;

Does not close adequately and allows water entrance and air seal problems ar;

Presents problems while opening or closing;

Time demanded to open or close is excessive;

Open or close just with external help;

Doesn't present sensibility to obstacles while closing.

alignment of the door to with the doorstop, as shown
on the right. This parameter is controlled by the wedge
set and the positioning of the door's fixation bearing,
both internal and external.
Sealing
The door's sealing is of extreme importance to avoid
water entrances, dust and even noises originated by
the air entrance. The superior wedge's set is
responsible for bringing the door closer to the body,
complementing the perpendicular movement. The

high forces applied to the wedges, which reduces it's
lifetime and may cause damage to the door's
doorstop. It's possible to obtain good seal when the
door's surface is aligned with the body's surface.
Parallelism with the body
This parameter is defined through the guide arm,
situated in the door's inferior part. The lenght of the
guide arm defines the position in which the door will
touch the doorstop during the door's perpendicular
movement. The door's approximation with the
doorstop must be parallel, and both sides must touch
the doorstop at the moment of closure.
Guide arm
Open the door
The door must be aligned with the body's lateral
lines, doorstop and with the doorstop's inferior part.
This can be obtained through the adjustment of the
inferior wedges.
Centralization
The existent cracks between the doorstop and the
door must approach on both sides equally. This
parameter can be reached when combining all the
factors mentioned before.
Velocity of closure
The complete movements of opening and closure
must be concluded in 4 to 6 seconds. Faster
movements might damage the trigger, doorstop and
the door's structure.

DOOR'S SENSIBILIZATION SYSTEM
The opened door signal is generated by an horizontal microswitch, as picture 3-Door sensibilization. This
opened door signal also send an electric signal to the green pilots of the retractable step.
This way, when the cam touches the horizontal micro-switches, the green pilots of the retractable steps
turns off.
