Abstract
The invention discloses an automatic clutch control system which comprises an outer shell, guide troughs, a motor fixing station, a speed switching mechanism, a displacement sensor device, a back dead plate, a front dead plate, a pressure spring, an outer cover and the like. The automatic clutch control system is driven by a direct current motor and changes operation mode of the motor from high-speed revolution to low-speed rectilinear motion through a deceleration mechanism and a screw, and thus the clutch is drawn to open. In order to control an executing mechanism accurately, the displacement sensor is mounted on the executing mechanism, signals of the displacement sensor are used as feedback signals of motor control, and a closed loop feedback control system is formed. Further, a spring auxiliary device is mounted on the executing mechanism in order to reduce load of the motor, and thus the action of the executing mechanism is convenient to control and demand on motor power is reduced. In order to guarantee that the executing mechanism does not twist or distort in motion, two guide troughs are milled in an upper side and a lower side of the outer shell, so that the moving components are guaranteed to move in a straight line in a horizontal direction. The automatic clutch control system has the advantages of being simple in structure, low in cost, convenient to operate and with good product succession.

Embodiment
A kind of automatic clutch control system adopts direct current generator 1 to drive, and drive motor 1 is connected with motor fixing seat 2, and motor fixing seat 2 fixes by bolt and shell.The high speed rotary motion of drive motor 1 overlaps 20 by push-and-pull and passes to the leading screw 10 that is connected therewith, 20 structures are overlapped in push-and-pull as shown in Figure 4, leading screw 10 is all to be connected with push-and-pull cover 20 by connecting pin 18 with drive motor 1, and assurance leading screw 10 and drive motor 1 are done and be synchronized with the movement.Between push-and-pull cover 20 and bearing support 19, two thrust ball bearings 21 are installed, are avoided leading screw 10 that the axial thrust of rocking and can bear substantially horizontal occurs when High Rotation Speed.Thrust ball bearing 21 ends are fixing by circlip for hole 22.The high speed rotary motion of leading screw 10 is converted into the low speed horizontal rectilinear motion of feed screw nut 11, feed screw nut 11 is bolted together with front connecting cylinder 9, rear connecting plate 12, side-to-side movement on the horizontal linear of feed screw nut 11 can drive the pull bar 8 that is connected with front connecting cylinder 9 and seesaw, thereby it is closed to pull clutch to disconnect, and realizes the automatic opening-closing of clutch.
Selected Compress Spring 9 will guarantee to be in all the time compressive state in whole movement process, and the elastic force that the minimal compression amount produces is greater than the clutch pulling force and motor provides the poor of power, the elastic force that maximum compressibility produces is less than the pulling force of clutch, so just can play power-assisted is provided, reduce the effect of the load of motor.
As Fig. 3, shell 5 is cut two navigation grooves in inner lengthwise position, in case moving link twists.And at shell 5 end-to-end distance center certain position along continuous straight runs crosscut one sections, be connected by screw with cover plate 3.Cover plate 3 tops are fixedly connected with displacement transducer 4, copper sheathing 15 and cover plate 3 transition fit, and copper sheathing 15 coordinates with sensor rotating shaft 16 upper gap, guarantees that sensor rotating shaft 16 can rotate freely.Fig. 5 sensor rotating shaft 16 bottoms cut out a navigation groove, and remain tangent with motion pin 17 upper ends.Motion pin 17 ends and rear connecting plate 12 transition fit, like this when feed screw nut 11 is done horizontal motion, rear connecting plate 12 just drives motion pin 17 and does the level of synchronization motion, motion pin 17 must tangently be connected and horizontal motion is converted into rotatablely moving of sensor rotating shaft 16 with sensor rotating shaft 16, displacement transducer 4 gathers displacement signal by the angle of swing of sensor rotating shaft 16, and signal is transferred to ECU judges and send instruction, as the control signal of motor 1 clockwise and anticlockwise, complete thereby complete by software instruction the real-time control that clutch disconnects closure.
Original state such as Fig. 1, clutch is in closed state, and feed screw nut 11 is in leading screw 10 high order ends, and for preventing the ball landing in feed screw nut 11, leading screw 10 high order ends will keep a segment distance with feed screw nut 11.Before this moment, connecting cylinder 9 just in time contacts with enclosing cover 7, and anti-twist pin 13 is at navigation groove 14 high order ends, and Compress Spring 9 is in maximum compressibility.
When automobile had begun step gear shifting, ECU sent signal drive motor 1 forward, and the high speed rotary motion of drive motor 1 overlaps 20 low-speed rectilinear movements that are converted into feed screw nut 11 by push-and-pull.Under the elastic force acting in conjunction of power that drive motor 1 provides and Compress Spring 6 compressed generations, drive pull bar 8 and move backward, thereby complete the separation of clutch.
As Fig. 2, clutch is in separated state, and feed screw nut 11 is in leading screw 10 low order ends, and rear connecting plate 12 contacts just with bearing support 19, in case stroke is excessive.This moment, Compress Spring 9 was in minimal compression, and the clutch pulling force that drive motor 1 bears is maximum.After completing gearshift, ECU sends 1 counter-rotating of order-driven motor, and feed screw nut 11 travels forward, thereby clutch returns to again closed state.
