In this case, the spring inside the actuator, previously
preloaded, provides a first motion to the elements (7, 5 and
3) and causes the electric motor, previously stopped, starting.
Subsequently, the stroke starts again until it meets a new
obstacle, represented by rod (5) limit stop on the power
takeoff box.
At this point, another axial backstop condition is created and
the above-mentioned operation is repeated: rod (5) tension
and electric motor switching off.
As long as the PTO engagement toothings stay on contact
with each other, the electric motor is switched off because
the pressure on the toothings (3 and 4) is kept by the spring,
inside the actuator.
The axial load on the engagement toothings is calibrated
(about 350 N) and gradually applied because the action
spring (inside the actuator) carries out a determined stroke
before being completely loaded. Toothing mouths (3 and 4)
shall therefore be protected against violent impacts assuring,
as to traditional mechanical or pneumatic system, less
engagement element wear and consequently, an higher
number of turns to be implemented before component
deterioration.
The functionality is more serviceable since the engagement
is softer and more silent as to the traditional systems.
Worm screw (7) limit stop is determined by axial load and
distance covered by control rod (5).
It is therefore possible to install on PTO having different
stroke values without modifying or adding compensation
elements.
POWER TAKEOFF DISCONNECTION
The PTO disconnection phase (Figure 6) is divided into two
motions:
The first motion consists in the worm screw return (7)
through the reversal carried out on the electric motor.
The second motion consists in the control rod retrocession
(5) through spring (6) and consequent shaft (4) sleeve (3)
disengagement.
The retrocession motion of the worm screw (7) do
not depend on the movement carried out by the
control rod (5); this guarantees, if the sleeve (3)
cannot be disengaged, the immediate backing of the
worm screw (7) without causing overloads to the
electric motor.
The PTO will be disconnected when the backstop
condition is over.
This event can occur if during the disengagement
request the shaft (4) is still in rotation or
pretensioned by a residual torque.
