Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the present embodiment comprises steering tiller 1 and steer motor 3, wherein coaxial setting angle sensor 2(adopts the potentiometer of record absolute value position in the rotating shaft of steering tiller 1), a coaxial sheathed torsion spring 8 outside this rotating shaft is used for realizing automatically reseting of steering tiller 1 simultaneously; The two ends of described torsion spring 8 are limited on the car body, and apply when mounted certain prefastening torque (being born by car body), steering tiller 1 is provided with driving lever simultaneously, when rotating steering tiller 1 to a direction, this driving lever can stir torsion spring 8 wherein an end it is turned an angle, increase the windup-degree (namely increasing moment of torsion) of torsion spring 8; When rotating steering tiller 1 to other direction, this driving lever can be stirred torsion spring 8 other ends turns an angle it, increases the windup-degree (namely increasing moment of torsion) of torsion spring 8, unclamp steering tiller 1 after, can be under torsion spring 8 effects self-return.Described steer motor 3 mouths are connection for transmission mechanism 4 and wheel flutter assembly 5 successively; The signal output part of described angular transducer 2 connects this example of steering controller 7(by signal wire (SW) and adopts the ZAPI-EPSAC0 controller, also can select Curtis1222 controller or Danaher ACD controller), be used for that angular transducer 2 is rotated the signal that produces and be sent to steering controller 7; Be connected by signal wire (SW) between this steering controller and the steer motor 3 simultaneously, be used for the work of control steer motor 3.
Described transmission device comprises intermeshing miniature gears 4-1 and big gear wheel 4-2, wherein miniature gears 4-1 is coaxially installed on the output shaft of steer motor 3, big gear wheel 4-2 is coaxially installed on the wheel flutter assembly 5, is used for power transmission with steer motor 3 to wheel flutter assembly 5, realizes turning to of vehicle.
Be coaxially installed with the potentiometer that the position transduser 6(that rotates synchronously with it adopts record absolute value position on the described miniature gears 4-1), the signal output part of this position transduser is connected with steering controller 7 by signal wire (SW).At this moment, angular transducer 2, position transduser 6, steering controller 7 and steer motor 3 connect to form a closed loop control system by signal, the steering order that angular transducer 2 sends is diverted the rear while of motor 3 execution by position transduser 6 detections and feeds back to steering controller 7 revises adjustment, accurately controls the synchronous execution that turns to.
The principle of work of the present embodiment is as follows: rotate steering tiller 1, drive torsion spring 8 and angular transducer 2 rotations, angular transducer 2 sends the voltage signal of variation to steering controller 7, steering controller 7 calculates the hand of rotation that steer motor 3 should be exported according to the positive and negative of this voltage signal and variation speed, the rotating cycle of rotating speed and steer motor 3, and drive steer motor 3 by the hand of rotation of calculating, (this performance at vehicle is exactly the steering direction of vehicle for rotating speed and rotating cycle rotation, speed and steering angle), drive wheel flutter assembly 5 by steering hardware 4 and rotate, realize turning to of vehicle.Simultaneously steer motor 3 also drives position transduser 6 by miniature gears 4-1 and rotates synchronously, utilizes position transduser 6 to detect steering state, and feeds back to steering controller 7 and revise adjustment, accurately controls to turn to.
When rotating steering tiller 1, torsion spring 8 rotates thereupon, in case unclamp steering tiller 1, under the effect of torsion spring 8, steering tiller 1 is got back to meta automatically, drive simultaneously angular transducer 2 and get back to meta, angular transducer 2 sends the angle voltage signal to steering controller 7, and 3 rotations of control steer motor make wheel flutter assembly 5 also get back to together meta.If operation steering tiller 1 after cutting off the electricity supply under the effect of torsion spring 8, is got back to meta with angular transducer 2 after steering tiller 1 unclamps automatically, wheel flutter assembly 5 still rests on original position at this moment; Adopt the potentiometer of record absolute value position because of angular transducer 2, so in case after the energising, angular transducer 2 can be automatically this moment steering tiller 1 position the angle voltage signal be transferred to steering controller 7, control steer motor 3 rotarily drives wheel flutter assembly 5 and gets back to meta, thereby has remained the position corresponding relation of steering tiller 1 and wheel flutter assembly 5.
