Belly switch (3) can prevent the operator will be squeezed, when vehicles are
driven towards (' Fw) encounters an obstacle, body touch belly to slow down or
start to switch
vehicles (' Bw) driven a short distance, then stop.If the handle is in the operating area
and the vehicle is not moving, please consider that this is still working.
5.3.2Working principle of braking
：
The brake is composed of magnetic yoke assembly 6, excitation coil 7, spring 2, brake disc 5,
armature 1, gear sleeve 4, mounting screw 3, etc.The brake is mounted on the end cover of the
motor and the mounting screw is adjusted to the specified air gap value.The gear sleeve is fixed on
the shaft, and its outer tooth is matched with the inner tooth of the brake disc. When working,
torque is transferred, and the brake disc can move axially on the gear sleeve.
When the brake excitation coil 7 is energized, the magnetic field generated by the coil
causes the armature 1 to attract to the yoke assembly 6, and the armature 1 is detached (released)
from the brake disc 5.At this time the motor drive shaft with brake disc 5 normal start and
operation.When coil 7 is cut off, the magnetic flux disappears and armature 1 is released. Spring 2
presses armature 1 and compresses the friction plate on the brake disc to generate friction, thus
achieving the braking purpose.
