Technical field
The utility model relates to the technical field of automobile gearbox actuator in the auto manufacturing, and particularly relevant for a kind of AMT clutch actuating mechanism.
Background technique
Along with the fast development of automobile pollution, automobile clutch is just presenting fast development trend.On the basis that keeps dry clutch and gearbox overwhelming majority assembly parts, the design that its operated by foot is partly changed into automatic clutch actuator presents fast development trend equally.
In the clutch actuating mechanism,, slow down to increase and turn round if directly use the driven by motor worm-and-wheel gear, very strong contradiction appears in the demand of speed and moment of torsion on the worm gear, and select the mechanism of self-locking for use, transmission efficiency is lower, is difficult to be implemented in the target of separating in the very short time this moment.And, be difficult to reach and also can be very high in the separation that does not have clutch under the situation of power assisting device for the requirement of motor.
Summary of the invention
In view of this, the utility model provides the AMT that a kind of performance is accurate, cost is low, not affected by environment clutch actuating mechanism.
The utility model proposes a kind of AMT clutch actuating mechanism, comprise motor and housing.The AMT clutch actuating mechanism also comprises transmission device and counterbalance spring.Wherein, transmission device comprises worm screw, worm gear and is fixed in the worm-wheel shaft of worm gear.Worm screw is connected in the output terminal of motor, and worm gear is meshed with worm screw.Counterbalance spring is in compressive state, and the one end is fixed on the housing, and the other end is connected in worm-wheel shaft.
Further, above-mentioned AMT clutch actuating mechanism also comprises wire drawing support and wire drawing, and the wire drawing support is fixed in worm-wheel shaft, and wire drawing is connected in the wire drawing support.
Further, above-mentioned wire drawing support is fan-shaped.
Further, above-mentioned AMT clutch actuating mechanism also comprises angle transducer, is arranged at the top of worm-wheel shaft.
The beneficial effects of the utility model are that the utility model adopts the worm gearing of self-locking and the counterbalance spring of variable force arm to combine.Counterbalance spring has certain pretightening force, provides power-assisted when clutch separation, has reduced the requirement of actuator to motor.Further, self-locking structure has prolonged the working life of motor.Whole actuator performance is accurate, reliable operation, and cost is low.
Description of drawings
Figure 1 shows that structural representation according to AMT clutch actuating mechanism of the present utility model;
Figure 2 shows that the partial enlarged drawing among Fig. 1.
Embodiment
For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Figure 1 shows that structural representation, Figure 2 shows that the partial enlarged drawing among Fig. 1, please in the lump with reference to figure 1 and Fig. 2 according to AMT clutch actuating mechanism of the present utility model.The AMT clutch actuating mechanism 1 that the utility model provides comprises motor 10, housing 11, transmission device 12, counterbalance spring 13, wire drawing support 14, wire drawing 15 and angle transducer 16.
As shown in Figure 1, transmission device 12 comprises worm screw 120, worm gear 121 and worm-wheel shaft 122.Worm screw 120 is connected with the output shaft of motor 10, and worm gear 121 intermeshes with worm screw 120, and worm-wheel shaft 122 is fixedly connected on worm gear 121.When actuator 1 worked, motor 10 rotations drove worm screw 120 rotations that are fixed on the output shaft, and worm screw 120 further can drive worm gear 121 and rotate with worm-wheel shaft 122.
In the present embodiment, be arranged with the wire drawing support 14 of fan shape on the worm-wheel shaft 122, adopt key to connect and carry out radial location.One end of wire drawing 15 is fixed on the wire drawing support 14, and the other end separates rocking arm with gearbox and is connected.
As shown in Figure 1, an end of counterbalance spring 13 is fixed on the housing 11 by the bulb bearing, and the other end is connected in worm-wheel shaft 122.Preferably, counterbalance spring 13 is fixed on the wire drawing support 14 by axle sleeve, locating stud.In the present embodiment, counterbalance spring 13 is in compressive state all the time.When carrying out the action of clutch separation, counterbalance spring 13 promotes worm-wheel shafts 122 and rotates together thereupon, and counterbalance spring 13 is in elongation in this process, and spring force is reducing, and the spring arm of force is increasing, and the running torque that provides of counterbalance spring 13 is more steady like this.
As shown in Figure 2, angle transducer 16 is installed in the end of worm-wheel shaft 122.Adopt angle transducer 16 measured angular displacements can extrapolate the stroke of release bearing accurately, further the closed loop control of realization system.
Working principle of the present utility model is: by mandatory switch activated motor 10, drive worm screw 120 by motor 10 and rotate, worm screw 120 drives worm gear 121 and worm-wheel shaft 122 rotates together.Because wire drawing support 14 is fixed on the worm-wheel shaft 122, worm-wheel shaft 122 rotations can drive wire drawing support 14 and rotate, and separate or combination thereby drive wire drawing 15 actions are finished clutch.
Because actuator's motor output power in the solenoidoperated cluthes separation process is bigger, power demand is less in the cohesive process, be balance motor power, the utility model adopts the counterbalance spring 13 with default decrement, be that counterbalance spring 13 has certain pretightening force when assembling, in whole motion process, all be in compressive state.
In clutch disengage process, counterbalance spring 13 provides power-assisted for the rotation of wire drawing support 14, drives wire drawing 15 motions, overcomes the Separating force of clutch, thereby greatly reduces the output power of motor; In the clutch cohesive process, thereby motor 10 counter-rotatings drive 14 rotations of wire drawing support, make counterbalance spring 13 compress.At this moment, diaphragm spring recover to drive wire drawing 15 and 14 rotations of wire drawing support, thereby makes counterbalance spring 13 compressions, under such situation, the requirement of motor is reduced greatly.
In the process of the separation of clutch or combination, because a lot of states that need to guarantee the motionless or slow motion of clutch positions are arranged, just require the long-time power supply of motor to guarantee the stability of position, like this electrical machinery life is had a significant impact.The worm gearing 12 that AMT clutch actuating mechanism that the utility model provides 1 adopts can self-locking, like this when motor 10 is stopped power supply, still can guarantee that clutch stops on some positions for a long time, wait for the carrying out of next action, thereby prolong motor working life.For instance, when the friction angle of worm screw 120 less than 3 ° of 17 ' times, worm screw 120 is rotated and can drive worm gear 121 and rotate, however worm gear 121 rotate and can not drive worm screw 120 and rotate, thereby realize the self-locking of actuator 1.
Concrete case study on implementation only is a preferable case study on implementation of the present utility model described in the utility model, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
