Theory
There are two ways to brake the swing motor: parking mechanical
brake and hydraulic brake. The parking mechanical brake is
installed inside the motor and mainly consists of a spring, a brake
piston and a brake friction plate. Pp solenoid valve lock state
mechanical brake control:
The input oil at the motor slack port Pp is pilot pressure oil and
is controlled by the rotary lock solenoid valve. When the solenoid
valve is locked, the Pp port pressure is released, and under the
action of the brake spring force, the brake piston tightens the
brake friction plate to realize the parking mechanical braking
function.
When the solenoid valve is opened, the pilot pressure oil enters
the brake oil chamber through the solenoid valve, opens the brake
piston, and the mechanical brake is opened. Rotation can be
achieved by manipulating the rotation.
Hydraulic brake control: Stop the rotary operation, the rotary
valve returns to the neutral position and blocks the inlet and
outlet oil circuits of the rotary motor, generating a large back
pressure on the return oil circuit to achieve braking.
