8.9 Braking
Braking performance depends on road conditions and the loading
conditions of car
The brake function can be activated in the following ways :
During driving, move the joystick back to the neutral position 0 (Figure 12)
to truck braking.
When driving, release the foot switch (Figure 7.6) to truck braking

Braking principle
：
as figure 11 shows including
：
Brake by
magnetic yoke assembly 6
、
Magnet exciting coil 7
、
Spring 2
、
brake disc 5
、
Armature 1
、
Geared sleeve 4
、
Mounting screw

.The brake is mounted on the end cap of the motor ,and the
mounting screw is adjusted to the specified air gap value.The
gear sleeve is fixed on the shaft .The external teeth cooperate
with the internal teeth of the brake disc.And the torque is
transmitted during operation.then the brake disc can move
axially on the gear sleeve .
When Magnet exciting coil 7 of brake is energized .the coil
produces a magnetic field that caused the armature 1 draw toward the magnetic
yoke assembly 6.Armature 1 detached from the brake disc 5(Release).Then the
motor drive shaft with brake disc 5 start and operate normally.When Magnet
exciting coil 7 is de-energized.,The magnetic flux disappears .Armature 1 is
released .and spring 2 process armature 1,then the friction plate on the brake
disc is pressed to generate frictional force for braking purposes
8.11Trouble
If there is any error or the car is not operate,Stop using and press the emergency
stop switch(Fig7.3).Parking the car in safe area if possible .Turn the key
counterclockwise and remove the key(figure 9).Notify the manager or contact
your after-sales service staff immediately .Use a special towing equipment
