The electric power steering system adopts the bidirectional potentiometer as the steering sensor, overcomes the difficulty of realizing electric power steering of the industrial vehicle with the operating handle, is suitable for detecting the variation of a rotating angle of the operating handle, improves the disadvantages of a traditional mechanical or hydraulic steering device, and is handy and flexible to steer.
Description
Technical field
The utility model relates to a kind of industrial vehicle, specifically relates to a kind of electric steering system of industrial vehicle.
Background technology
Current, the electric steering system technology is applied to floor conveying equipment for known technology, particularly the electric steering system technology is applied to make on most of minicar and the car turn to more flexible and travel safer.The electric steering system technology is being represented the developing direction of steering hardware, it is on the basis of mechanical steering system, according to the dtc signal that acts on the bearing circle, make motor produce the auxiliary force of corresponding size and Orientation by electronic control package, assist chaufeur to carry out steering operation, and obtain the Fu of best cornering properties.
The electric steering system of prior art, generally form by wheel steering input (comprising stepping motor), electronic controller (comprising control unit and driver element), steering hardware (comprising steer motor, retarder, manual steering gear and car load wheel flutter) and battery feed etc., by the moving stepping motor of hand of rotation dribbling, send impulse singla, electronic controller receives and turns to about carry out according to designated program control steer motor the instruction back, overcome the shortcoming of machinery or hydraulically powered side thruster, accomplished to turn to light, flexibly, accurately, efficient.
Recently, development along with electric industry vehicle, its steering swivel system is replaced by electric steering system by original mechanical drive or power hydraulic system, it as the patent No. 200920123916.0 fork truck electrical steering device, by the moving stepping motor rotation of hand of rotation dribbling, stepping motor sends impulse singla and receives behind the impulse singla according to the turning to and rotating speed of the programming control steer motor output shaft of inner setting for EPS controller, EPS controller, thereby controls turning to of fork truck indirectly.
Thereby, electric steering system is applied to also become on electronic order-picking trucks, transport trolley and the forklift inexorable trend of technical development, but what electronic order-picking trucks etc. were different with fork-truck steering is: it turns to input media is control lever or operating handle etc., and the input media that turns to that uses on the fork truck is bearing circle, therefore, on electronic order-picking trucks, transport trolley, adorn electric steering system, need with turn to input media---the characteristic of operating handle is suitable.
Summary of the invention
The utility model provides a kind of electric boosting steering system of industrial vehicle, solves ribbon gymnastics in the prior art and makes to be equipped with on the electric industry vehicle of handle and so on electric boosting steering system and realize the problem that turns to.
The electric boosting steering system of industrial vehicle, mainly be by turn to input media, with turn to input media bonded assembly rotation direction sensor, with rotation direction sensor signal bonded assembly electronic controller, with electronic controller output end signal bonded assembly steer motor, the steering hardware that links to each other with steer motor is formed, the wherein said input media that turns to is an operating handle, and described rotation direction sensor is two-way potential device.
Operating handle described in the technique scheme often is set on the short-haul operation industrial vehicle of order-picking trucks, transport trolley, forklift and so on, when operating personal rotating operation handle, two-way potential device is exported cooresponding voltage signal and direction signal according to the rotational angle size and the rotation direction of operating handle, steer motor is controlled and driven to electronic controller by detecting two-way potential device voltage signal and direction signal, steer motor passes to steering hardware with the moment of torsion of output then, thereby realizes the electrical steering of car load.
Described two-way potential device be installed in operating handle bonded assembly steering shaft on.
On the described steering shaft torsion spring is installed, in other words, torsion spring provides damping due to rotation, like this, can realize the automatic centering function on the one hand, allows operating personal have sense of direction more on the other hand when turning to.
Above-mentioned two-way potential device, electronic controller, steer motor, steering hardware all are existing technology and product on the market.
The utlity model has following effect:
1, adopt two-way potential device as rotation direction sensor, overcome the industrial vehicle that has operating handle and realized the difficulty of electric power steering, be more suitable for the angle that the detecting operation handle rotates by two-way potential device and change, and in the prior art stepping motor to be more suitable in handling device be the industrial vehicle of bearing circle and so on.
2, adopt electric steering system to realize Vehicular turn, improved the shortcoming of traditional machinery or hydraulically powered side thruster, turn to light, flexible.
Description of drawings
Accompanying drawing is a theory structure scheme drawing of the present utility model;
Among the figure: 1-operating handle, 2-torsion spring, 3-steering shaft, the two-way potential device of 4-, 5-electronic controller, 6-telltale, 7-steer motor, 8-steering hardware, 9-limit sensors.
The specific embodiment
The electric steering system of industrial vehicle, mainly form by operating handle 1, two-way potential device 4, electronic controller 5, telltale 6, steer motor 7 and steering hardware 8 and limit sensors 9, wherein operating handle 1 is provided with execute key and movable being connected on the car body, and telltale 6 is arranged on is convenient to the position that operating personal is observed most on the car body.
As shown in the figure, the end of operating handle 1 connects a steering shaft 3, steering shaft 3 and two-way 4 coaxial connections of potential device, steering shaft 3 is provided with the torsion spring 2 of a control steering torque, two-way potential device 4 is connected with electronic controller 5 signals, and telltale 6 is connected with electronic controller 5 signals, and limit sensors 9 is connected with electronic controller 5 signals, electronic controller 5 mouths are connected with steer motor 7 signals, and the dynamical axis of the output shaft of steer motor 7 and steering hardware 8 is connected.
Rotating operation handle 1, drive two-way potential device 4 rotations by steering shaft 3, two-way potential device 4 sends signal and gives electronic controller 5, electronic controller 5 receives behind the signal according to the turning to and rotating speed of programming control steer motor 7 output shafts of inner setting, thus the handling maneuver by steering hardware 8 control fork trucks.Meanwhile, torsion spring 2 is to operating handle 1 feedback damping.Operating handle 1 rotation amplitude is big more, and damping is big more.Therefore operating personal can hold the degree that turns to intuitively.Accurate for guaranteeing to turn to, limit sensors 9 sends the wheel flutter angle position signal, electronic controller 5 reads signal from limit sensors 9, automatically detect the initial angle position of this handling maneuver steering front wheel, the angle position of wheel flutter is shown on the telltale 6 all the time guaranteeing in course of action.
