A Hall Effect speed sensor which produces a square wave. 0-5Vdc signal in
response to a rotating 30 tooth wheel coupled to the rear propshaft inside the
Transfer Case. Each rotation of the rear propshaft will result in 30 speed sensor
pulse.
A Hall Effect speed sensor which produces a square wave. 0-5Vdc signal in
response to a rotating 30 tooth wheel coupled to the front propshaft inside the
Transfer Case. Each rotation of the front propshaft will result in 30 speed sensor
pulse.
An Electromagnetic clutch used to control the amount of torque applied to the
front propshaft.
TM
Torque on Demand .
Duty Cycle is the time the EMC is on divided by the period in which it is being
modulated.
A minimum amount of duty cycle applied to the EMC.
A condition where the front propshaft is turning at a rate which is faster than the
rear propshaft.
A condition where the rear propshaft is turning at a rate which is faster than the
front propshaft.
The highest (numerically lowest = 1 :1) gear ratio between the input and outputs
of the Transfer Case.
The lowest (numerically highest = 2.48:1) gear ratio between the input and outputs
of the Transfer Case.
A switch which selects the desired gear ratio.
Electric motor which changes the Transfer Case range.
A set of 4 Gray code switches which provide feedback to the TCCU indicating the
position of the Shift Motor.
A switch on vehicles equipped with a manual transmission which indicates that
the clutch pedal is depressed.
A switch on vehicles equipped with an automatic transmission which indicates
that the transmission is in neutral.
The vehicle speed above which Transfer Case shifts are disallowed. Vehicle speed
is indicated by propshaft speed measurement.
