Creeper interlocking mechanism:
1,4 – fork; 2,3 – pusher; 5,6,7 – gear.
To engage the creeper, it is necessary,
first of all, to disengage the gears (5)
and (6) in the gearbox. It is achieved by
moving the pusher (2) to the right to the
position fixed by the spring-loaded ball.
Here the fork (1) fixed on the pusher (2)
disengages the gears (5) and (6) and
brings the gear (5) into complete mesh
with the intermediate gear (8) (see Fig-
ure “Creeper”) of the creeper. Then the
gear (7) is brought into mesh with the in-
termediate gear (8) (see Figure
“Creeper”) by moving the pusher (3)
(see Figure “Creeper interlocking
mechanism”) with the fork (4) to the left
to the fixed position.
Thus, the power flow from the driving
gear (1) (see Figure “Creeper”) is
brought to the driven one (9) of the
gearbox. The interlocking mechanism
excludes the possibility of simultaneous
movement of both fork and, respectively,
rods as well as ensures the priority of
their engagement.
