TRAVEL MOTOR

Parking brake
The friction disc (2) and the disc (1) are connected via
the spline. The friction disc (2) and the disc (1) are
pressed against the flange holder (6) by the springs (4)
via the brake piston (5). The friction force between these
discs generates a braking torque that works to prevent
the cylinder block (3) from rotating.
When the pressure oil is introduced into the motor, the oil
flows from the parking brake release port (7) into the
brake piston chamber (8). The oil pressure overpowers
the spring force and moves the brake piston (5) to the
right. This generates a clearance between the friction
disc (2) and the disc (1) that works to release the parking
brake function.
Once the motor stops, no pressure oil flows into the park-
ing brake release port (7), and the parking brake force is
operated by the spring (4).
Reduction gears
The reduction gears consist of simple two-stage plane-
tary gear assemblies connected in series. Each plane-
tary gear assembly consists of a sun (input) gear, an in-
ternal ring gear with teeth that point inward, and planet
gears mounted on a carrier. The sun gear “floats” within
the planet gears so as to attain a uniform load distribution
over multiple gear mesh points.
The motor drives the 1st-stage sun gear (1), which in turn
drives the 1st-stage planet gears (2). Since these planet
gears (2) are engaged with the ring gear (3), their rota-
tion is transmitted to the 1st-stage carrier (4).
The 1st-stage carrier (4) is coupled directly to the 2nd-
stage sun gear (5), which drives the 2nd-stage planet
gears (6).
The 2nd-stage carrier (7) is a part of the motor housing
and thus non-rotating, which means that the main torque
is output to the ring gear (3). The output flange rotates in
the direction opposite that of the input rotation.
