Working of negative brake
When the operating pressure is supplied to the brake piston (21) through the spool (simultaneous
peripheral operation online) built in the shaft casing (1), the negative brake is released.
When the pressure does not work, the brake always runs.
The force of a brake is generated by the frictional force among a separate plate (20) fixed by shaft
casing, parking piston (21) and a frictional plate (19) connected through spline outside a cylinder
block (10).
When a pressure does not work on the part of piston, brake spring presses brake piston; oil in a
brake room flows into the drain of a motor through an orifice; in that time, brake piston compresses
a frictional plate and a detached plate in the middle of shaft casing (1) and brake piston (21)
according to the force that presses 10 pieces of brake springs (67, 68); finally, it makes a frictional
force.
This frictional force helps the brake fixing a turning shaft (6) connected by a cylinder and spline
operated.
