Specific embodiment
Specifically describing the preferred embodiment of the present invention with reference to the accompanying drawing, wherein attached drawing constitutes the application a part, and
Together with embodiments of the present invention for illustrating the principle of the present invention, it is not intended to limit the scope of the present invention.
Electro-motive vehicle is used as engineering truck (such as dump truck), and lifting device generally uses the scheme of electric cylinder 8.Often
One motor is installed, for driving electric cylinder 8 on root electric cylinder 8.Disadvantage is fairly obvious: 8 volume ratio Normal hydraulic of electric cylinder
Cylinder volume is big, system difficult arrangement, due to needing that multiple motors are arranged on electric drive vehicle, increases itself weight of electric drive vehicle
Amount, reduces the payload of electric drive vehicle.It is an object of that present invention to provide a kind of electric drive vehicle-mounted lifting devices, solve general
The disadvantages mentioned above of electric drive vehicle-mounted lifting device.
As shown in Figure 1, the embodiment of the invention provides a kind of electric drive vehicle-mounted lifting device, electric drive vehicle-mounted lifting device
It is mounted on the vehicle frame of electric drive vehicle, comprising: bridge motor 1, drive clutch 2, lifting clutch 5, transfer case 6 and electric cylinder 8；
Bridge motor 1 is Dual-output shaft motor, and 2 output shafts are connect with drive clutch 2 and lifting clutch 5 respectively；Drive clutch 2
It is connect with the driving wheel of electric drive vehicle；The output shaft of lifting clutch 5 is connect with transfer case 6；The output shaft of transfer case 6 passes through act
Drive shaft is risen to connect with the input terminal of electric cylinder 8；The output end of electric cylinder 8 is equipped with switching trunnion 14.When bridge motor 1 is used to as electricity
When vehicle being driven to provide driving power, drive clutch 2 is connected, and lifting clutch 5 disconnects, and bridge motor 1 imparts power to driving
Wheel drives electric drive vehicle mobile；When bridge motor 1 is used to provide power for lifting, drive clutch 2 is disconnected, and lifts clutch 5
Power is passed to electric cylinder 8 by transfer case 6 by connection, bridge motor 1, drives the flexible of electric cylinder 8, completes lifting or decentralization.
Trunnion 14 is usually hinged by lifting component with electric drive vehicle, for example, the container of dump truck.The multiplexing of electric drive vehicle-mounted lifting device
The bridge motor 1 of electro-motive vehicle is inputted as power, and without installing motor on electric cylinder 8, system weight is light, small in size.
For electric cylinder 8, due to not having motor directly to provide power, and power was transmitted by lifting drive shaft
Come, existing electric cylinder 8 can not be continued to use, and need individually to design the progress of electric cylinder 8.Specifically, in the embodiment of the present invention,
Electric cylinder 8 includes cylinder barrel 10, lead screw 11, push rod 13；Lead screw 11 is arranged in cylinder barrel 10, and drives with the lifting for penetrating cylinder barrel 10
Axis is connected by gear set；The inside of cylinder barrel 10 is arranged in the starting point of push rod 13, and is equipped with the nut 12 cooperated with lead screw 11,
