Fig. 7: Holding brake section
As a safety requirement in mobile applications a parking brake may be provided to
ensure that the motor cannot turn when the machine is not in use.
The brake is mounted by the way of the rear case (
2
) and brake shaft (
16
).
A disc pack (
11
), with alternate discs splined to the brake shaft and brake housing,
is compressed by the force of a disc spring (
10
) acting through a piston (
12
). The
friction between the discs generates a holding torque.
