Abstract
The utility model discloses a forwards-moving forklift steering and centering mechanism. A steering servo motor drives a steering wheel to rotate and a steering angle sensor for measuring a rotating angle are arranged on a steering pillar connected with the steering wheel. The forwards-moving forklift steering and centering mechanism is further provided with a steering controller and used for receiving switching value signals of a centering switch arranged in a cab, receiving steering angle signals collected by the steering angle sensor and outputting the centering signals to the servo motor. The one-key steering wheel centering technology is utilized so that a driver can make the steering wheel go back to a center position in the working environment which is high in strength, poor in view and narrow in space and under the condition that a direction is occasionally deviated, and therefore the driver can better master positions and better master sense of direction. In addition, the forwards-moving forklift steering and centering mechanism does not conflict with centering of the steering wheel after a power-on self-test, large modification does not need to be performed on the controller, and extra resources of the controller are not consumed.
Description
Technical field
The utility model relates to the technical field of industrial vehicle, relates in particular to the electri forklift steering control system.
Background technology
Along with the quickening of logistlcs technology development and process of industrialization, the fork truck technology has obtained significant progress.And environmental protection consciousness is strengthened day by day, and the proportion of elec. vehicle is improved, in the electri forklift steering swivel system; traditional majority fluid-link steering; part electricity consumption steering swivel system by manual bearing circle control steering motor, turns to wheel flutter in this system.
For example nowadays be usually used in the vehicle of storing in a warehouse, reach truck, its working excavation is narrower, surface roughness is little, and chaufeur cannot see wheel flutter steering angle direction, and the turning probability is bigger continuously in this environment, general chaufeur is difficult to rapid centering direction, in case the steer direction mistake very easily bumps, give personnel, vehicle, goods and shelf bring danger.
Nowadays Chang Yong centering technology is the installing angle potential device, and by the rotational angle of bearing circle, corresponding sensing data transfers to instrument, shows the steering angle value.Because sensor has certain error limit, can bring the bigger error of angle if deviation occurs when mounted.Chaufeur needs a correction in complex operating environment the time, technology during switching on and shutting down can realize returning automatically, but resource is not only wasted in switching on and shutting down frequently, and influence the components and parts life-span such as automatically controlled, instrument.
The utility model content
Technical problem to be solved in the utility model is to realize a kind of technology that can a key makes wheel flutter centering.
To achieve these goals, the technical solution adopted in the utility model is: reach truck turns to centering body, with the servomotor that turns to that drives its rotation is installed on the Steering gear that bearing circle is connected, and the steering angle sensor of measuring the anglec of rotation, this mechanism also is provided with steering controller, its reception is arranged on the switching value signal of the centering switch in the operator's compartment, and receives the steering angle signal that steering angle sensor is gathered, and output centering signal is to turning to servomotor.
The described servomotor output speed feedback signal that turns to is to steering controller.
Advantage of the present utility model is: utilize a key wheel flutter centering technology can make chaufeur in high strength, the visual field is bad, the space is narrower working environment, once in a while the deviation in direction situation can appear in time, also wheel flutter can be back to meta, make chaufeur can better hold the position, better hold sense of direction.And do not conflict with the wheel flutter centering after the startup self-detection, need not to do bigger change at controller, do not consume the controller extra resource.
Description of drawings
Below the content of every width of cloth accompanying drawing expression in the utility model specification sheets and the mark among the figure are made brief description:
Fig. 1 turns to the centering body structural representation for reach truck;
Mark among the above-mentioned figure is: 1, centering switch; 2, steering controller; 3, turn to servomotor; 4, steering angle sensor; 5, bearing circle.
The specific embodiment
The utility model centering body need be done change to existing steering controller 2 principles, increases interface and program, cooperates to turn to servomotor 3 to be achieved.Specifically, exactly the Steering gear that is connected with bearing circle 5 be equipped with drive its rotation turn to servomotor 3, and the steering angle sensor 4 of measuring the anglec of rotation, a centering switch 1 is installed in the operator's compartment, can pass through operating in a key, finish centering work, this centering switch 1 is connected with steering controller 2 and exports the switching value signal to it, the steering angle signal that steering angle sensor 4 is gathered Steering gear also is delivered to steering controller 2, this steering controller 2 also is connected with turning to servomotor 3, to the time of its output control wheel flutter centering and the signal of speed, receive the feedback speed signal that turns to servomotor 3 feedbacks simultaneously.Owing to can control time and the speed of wheel flutter centering, then the time can be controlled in reasonable range, can effectively reduce the noise that turns to the samsara timing belt, increase traveling comfort.
During work, chaufeur is pressed centering switch 1 as required, output had the signal of time and velocity information to turning to servomotor 3 after then steering controller 2 received on-off signal, control its work, forward meta to until wheel flutter, namely the steering angle that returns of steering angle sensor 4 is at the signal of meta.
By reference to the accompanying drawings the present invention has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
Claims (2)
1. reach truck turns to centering body, it is characterized in that: be equipped with on the Steering gear that bearing circle (5) is connected drive its rotation turn to servomotor (3), and the steering angle sensor (4) of measuring the anglec of rotation, this mechanism also is provided with steering controller (2), its reception is arranged on the switching value signal of the centering switch (1) in the operator's compartment, and receive the steering angle signal that steering angle sensor (4) is gathered, and output centering signal is to turning to servomotor (3).
