⚫
By directly moving the accelerator button (Figure 7.7) from one driving
direction to the opposite direction, the truck will regeneratively brake until
it starts to drive into the opposite direction.
⚫
Release the foot switch while driving to achieve truck braking.

Brake structure &Brake Schematic
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 3 .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

Trouble
If there is any error or the car is not operate, Stop using and press the emergency
stop switch. Parking the car in safe area if possible .Turn the key counterclockwise
and remove the key(figure 10).Notify the manager or contact your after-sales
service staff immediately .Use a special towing equipment /lifting equipment to
pull the truck out of the operating area if necessary .
8.10Emergency situations
Keep a safe distance in an emergency situation or the car is turned over. Press the
emergency stop switch and all electrical functions will stop.
