Description
Technical field:
The invention belongs to electri forklift technical field, relate generally to a kind of electri forklift electricity steering direction dish signal and export and spacing
Device.
Background technology:
Electri forklift steering mode existing machinery formula, fluid pressure type, electricity booster type, pure electric-type, wherein fluid pressure type is the most universal, and is somebody's turn to do
Turn to pattern to there is the shortcomings such as energy consumption is big, noise is big, will progressively be replaced by electricity booster type and pure electric-type.Pure electricity turns to and is divided into
Speed follower formula and two kinds of control models of location following formula, the output of this hand-wheel signal and stopping means are for location following formula control
The turn signal collection of system processed.The most general electric turn signal generating means, does not all have spacing, uses speed follower
Formula course changing control, under this control model, the physical location of deflecting roller and the not exclusive corresponding relation in steering wheel turned position, control essence
Spend the highest.
Summary of the invention:
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of electri forklift electricity steering direction dish signal output
And stopping means, when different automobile types steering wheel maximum turns to number of turns difference, the versatility of structure, and improve when turning to
Operation comfort.
The present invention is achieved by the following technical solutions:
A kind of electri forklift electricity steering direction dish signal output and stopping means, include and coordinate the side being arranged on steering spindle end
To dish, cubicle switch, it is characterised in that: described cubicle switch is fixed on steering column, on described steering column and steering spindle

On be combined with spacing screw, the steering spindle of the upper and lower side of described spacing screw is respectively installed with damping spring, described limiting wire
Female side is provided with the stop screw being positioned in strip stopper slot, and described steering spindle is set with yielding coupling, described
The bottom of yielding coupling is provided with multi-turn digital regulation resistance by L-shaped potentiometer support.
The upper end of described multi-turn digital regulation resistance is inlaid in the endoporus of yielding coupling, and described L-shaped potentiometer props up
The upper end of frame is fixed on steering column, bottom and the cannelure snap fit of multi-turn digital regulation resistance.
The bottom of described steering column has fixed mount, described fixed mount to be provided with the otic placode for connection of symmetry, institute
The bottom stating otic placode is provided with installing hole.
The output of this hand-wheel signal and stopping means, by leading screw, screw transmission, by the rotary motion of steering wheel, are converted to
The stop screw linear motion being positioned on screw, by changing the size of stopper slot, the maximum that can change steering wheel turns to the number of turns,
The damping spring of the most spacing screw both sides, can realize wheel steering power and be directly proportional to steering angle, steering spindle and many number of turns
Word potentiometer is connected by shaft coupling, and turn signal and steering wheel angle can realize one_to_one corresponding.Use this stopping means, can be real
Existing location following course changing control, steer wheel position is the most corresponding with steering wheel turned position, facilitates driver to judge to turn to position of wheel
Put, when turning to, more convenient, safer.
The invention have the advantage that
1, the output of this signal and limit device structure are succinct, easy for installation, it is not required that to increase big cost, make on fork truck
With, steering angle signal can well be exported, improve the safety and stability of operation.
2, changing maximum turns to the number of turns simple；
3, steering force is directly proportional to steering angle, steering wheel operation good hand touch；
4, steering wheel position and steer wheel position can realize one_to_one corresponding, and driver behavior is safe, light.
