AUTOMATIC TRANSMISSION AND DIFFERENTIAL
the shoe. The increasing rate of torque
due to an increase in the rotational
speed is considerably lower than in the
second range; consequently, this is
what is called a torque limiter condi-
tion.
Further, the centrifugal force of the
main spring is balanced and offset by
the force with which the spring is
pushed, and there is no change in the
force pushing the shoe.

4) Fourth range (high-speed range)
The main spring deflects outward due
to its own centrifugal force, and
separates from the weight. Thus, the
upward pressing load with which the
weight pushes the spring dies away.
In the third range the centrifugal force
of the main spring is offset by the
pressing load of the weight. In the
fourth range, however, because the
centrifugal force of the main spring is
carried to the shoe as it is, the transfer
torque of the clutch greatly increases
as does the torque capacity somewhat
increases accordingly.
