Description
Technical field
The utility model relates to a kind of fork truck, relates in particular to a kind of two four fulcrum fork trucks that drive.
Background technology
Electri forklift is meant the fork truck that carries out operation with electricity; Great majority all are to be battery-operated, and its effect is to store limited electric energy, use in suitable place; Its principle of work is converted into electric energy to chemical power exactly, the just this storage battery of dress in the storage battery of electri forklift.Electri forklift uses motor-driven, existing four fulcrum fork trucks, and it is big to take up room, the car load underaction, and a little less than the three fulcrum fork truck propulsive efforts, takeoff output is not enough, a little less than the hill climbing ability.
Summary of the invention
The utility model provides a kind of propulsive effort the strong and two flexibly four fulcrum fork trucks that drive of structure to deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of pair is driven four fulcrum fork trucks, comprises drive system, steering swivel system and vehicle frame, and drive system comprises controller, motor and drive wheel; Vehicle frame comprises the headstock and the tailstock, and vehicle frame is provided with protective cover, and described controller is two; Described motor is two, and described drive wheel is two; Two motors of two the independent respectively control of controller, two motors connect two drive wheels respectively.Dual-motors Driving, respectively through two controller controls, two controllers are realized the independent control of motor, takeoff output is reasonable when turning to.Protective cover is isolated the top, protection staff's safety.
As preferably, drive system also comprises two change speed gear boxs, and change speed gear box is located between motor and the drive wheel.Change speed gear box drive axle one, two gearbox designs adapt to Dual-motors Driving.
As preferably, motor and drive wheel all are positioned at headstock, and adjacent near, change speed gear box is positioned at drive wheel inside.Motor, change speed gear box and drive wheel compact conformation, the center is low, makes whole vehicle stability better.
As preferably, motor is provided with deflector.The rotation direction of deflector control wheel flutter.
As preferably, steering swivel system comprises steeraxle and wheel flutter.
As preferably, be provided with rubber in the middle of the steeraxle, steeraxle is connected through rubber with vehicle frame.Steeraxle is installed and is adopted rubber shock-absorbing.
As preferably, be equipped with on the steeraxle and turn to potentiometer, turn to potentiometer to link to each other with controller.Through turning to potentiometer to realize the steering angle information collecting, controller is more reasonably controlled two motors through handling the information of sampling.
As preferably, the angle between steeraxle and the wheel flutter is 77-257 °.Center line with steeraxle is a line of reference, and the maximum angle that wheel flutter rotates to the headstock direction is 103 °, and the maximum angle that wheel flutter rotates to tailstock direction is 77 °.Single tyre rotation gets angle and reaches 103 °, and car load is more flexible, and turn radius is littler.The structure design of steeraxle makes angle of turn big, and is convenient, flexible.
According to the technical scheme of the utility model, the Dual-motors Driving powerful, hill climbing ability is strong; It is compact more that drive system takies the car load space, and the car load center of gravity is lower, and stability is better.Conventional design before comparing, it is bigger that single tyre rotation gets angle, can reach 103 °, and car load is more flexible, and turn radius is littler.Realized the car load original place around preceding two drive wheel center-points revolution action, car load is more flexible.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
A kind of pair is driven four fulcrum fork trucks, comprises drive system, steering swivel system and vehicle frame 1, and vehicle frame 1 comprises the headstock 11 and the tailstock 12.Vehicle frame is provided with protective cover 4.
Drive system comprises controller 21, motor 22, change speed gear box 23 and drive wheel 24.Two controllers 21 are controlled 22, two motors 22 of two motors respectively and are connected 23, two change speed gear boxs 23 of two change speed gear boxs respectively and connect two drive wheels 24 respectively, thereby make motor 22 independent controlling and driving take turns 24 speed; One of them motor 22 top is provided with deflector 31.It is compact that drive system takies the car load space, and the car load center of gravity is low, good stability.
Steering swivel system comprises deflector 31, steeraxle 33, turns to potentiometer 34 and wheel flutter 35.Wheel flutter 35 is subordinate wheels, the rotation direction of deflector 31 control wheel flutters 35, and wheel flutter 35 passes through bolted connection with steeraxle 33; Steeraxle 33 is provided with and turns to potentiometer 34, the information that turns to potentiometer 34 to collect steering angle, and controller 21 is controlled two motors 22 through handling the information of sampling.The centre of steeraxle 33 is provided with rubber 32, through rubber 32 steeraxle 33 is installed on the vehicle frame 1, adopts rubber 32 dampings during installation.Steeraxle 33 adopts big angle of turn steeraxle, and the rotational angle maximum of wheel flutter 35 can be 103 °, and car load is more flexible, and turn radius is littler.
