Specific embodiment
In view of this, core of the invention is to provide a kind of fork truck braking control system, it is not only simple in structure, arrangement side
Just, additionally it is possible to the phenomenon that avoiding the occurrence of oil leak, to effectively promote the reliability of fork truck braking.
Another core of the invention, which also resides in, provides a kind of fork truck brake control method.
To make those skilled in the art more fully understand the present invention program, below connection with figures and specific embodiment pair
The present invention is described in further detail.
Fork truck braking control system disclosed in the embodiment of the present invention, including motor 1, and the power train being connected with motor 1
System；Brake 2 for being connected with motor 1；For providing the battery of power supply for motor 1；For controlling the control of motor 1
Device；Gas pedal and brake pedal for being electrically connected with the controller.
When carrying out brake when driving, operator's brake pedal, brake pedal transmits signal
To controller, controller detects whether speed is 0 first, and when detecting speed not is 0, controller detects brake pedal letter
Number, while accelerator pedal signal is also detected, when controller detects that brake pedal signal is greater than preset value, accelerator pedal signal is small
When preset value, controller control brake 2 implements braking, and motor 1 generates electricity at this time, and the regenerative current of motor 1 is stored in electric power storage
Motor 1 being continued as in pond, power supply being provided, motor stalls drive transmission system to stop operating, and parking may be implemented in fork truck.
It is to be understood that the size of the regenerative current of motor 1 can be determined according to the depth of brake pedal,
A set of control system can be set again, the regenerative current size of motor 1 is set in control system.
It should be noted that brake 2 can be set in the input terminal of motor 1, also can be set in the output of motor 1
End.
It should be further noted that brake 2 can be electromagnetic brake, or mechanical brake.
When fork truck is counterbalanced lift truck, transmission system includes retarder 3, and the drive axle 4 being connected with retarder 3,
And it is set to the driving wheel 5 at 4 both ends of drive axle.When brake 2 is implemented to brake, motor 1 shuts down, and is connected with motor 1
Retarder 3 and drive axle 4 shut down, therefore, driving wheel 5 shuts down, and fork truck is out of service.
When fork truck is reach truck, transmission system includes retarder 3, and the driving wheel 5 being connected with retarder 3, when
