Description

Actuating device clutch

Technical field

This utility model be related to a kind of adjust as needed drivewheel and driven pulley joint or detached actuating device from Close mechanism.

Background technology

Clutch, in other words clutch be between power source and driven system, for engage or cut off power transmission Part.

Slip clutch is a now most widely used class clutch, it substantially by driving part, slave unit, Compacting part and control member four part composition.Driving part, slave unit and compacting part are to ensure that clutch is in joint State simultaneously can transmit the basic structure of power, and control member mainly makes the device of clutch separation.Existing slip clutch Generally to be kept the joint of driving part and slave unit by compacting part, driving part is separated with slave unit, needs to apply Plus an applied external force；There is also another kind of situation, driving part state usual with slave unit be separate, driving part with The joint of slave unit needs to apply a lasting applied external force.Existing slip clutch complex structure, manufactures and ties up Shield high cost.

Utility model content

Main purpose of the present utility model is to provide a kind of simple, efficient actuating device clutch.

In order to realize above-mentioned main purpose, the actuating device clutch that this utility model provides includes being arranged on fixation Angle demodulator on seat, is arranged on the rotating shaft on angle demodulator, is arranged on the swing seat in rotating shaft, is arranged on the master on swing seat Driving wheel, and it is arranged on the driven pulley in fixed seat.When needing to engage drivewheel with driven pulley, angle demodulator makes rotating shaft turn A dynamic angle, so that swing seat swings an angle, adjustment then is arranged on and actively takes turns to an ad-hoc location simultaneously on swing seat Contact with driven pulley；Meanwhile, drivewheel rotate and with driven pulley friction, frictional force makes drivewheel engage with driven pulley；Now, angle Degree actuator can stop the active force to drivewheel, and in the presence of frictional force, drivewheel and driven pulley continue to remain engaged with simultaneously Transmission；When needing to separate drivewheel and driven pulley, drivewheel stops power output, under gravity, drivewheel with driven Wheel separates.

From such scheme, because this actuating device clutch to keep drivewheel and driven pulley without compacting part Joint, without the joint that will apply a lasting applied external force and to keep drivewheel and driven pulley；Drivewheel with from The separation of driving wheel is without actively applying applied external force.This actuating device clutch structure is simple, can efficiently realize leading The joint of driving wheel and driven pulley or separate.

One preferred scheme is that actuating device clutch angle demodulator is steering wheel, electromagnet mechanism or motor One of mechanism.Steering wheel is made up of motor, train of reduction gears, output shaft, sensor and control circuit, can be according to input letter Number, export the axle anglec of rotation specified；The output shaft of steering wheel is coaxial with rotating shaft.Electromagnet mechanism includes electric magnet and connection rotating shaft Rocking arm, when the solenoid is energized, electric magnet attracts rocking arm to rotate around the axis an angle, so that one angle of axis of rotation Degree.Motor mechanism includes motor, connects the cam of rotor and the rocking arm of connection rotating shaft, and when motor rotates, cam makes to shake Arm rotates around the axis an angle, so that one angle of axis of rotation.

Alternatively, swing seat is provided with extension spring, compression spring or torsionspring, spring is connected with fixed seat, is used for Mitigate the power that rotating shaft is born.

Brief description

Fig. 1 is this utility model actuating device clutch embodiment schematic diagram.

Fig. 2 is the embodiment of this utility model actuating device clutch (angle demodulator is motor mechanism).

Fig. 3 is the flow chart of this utility model actuating device clutch method of work embodiment.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Specific embodiment

Referring to Fig. 1, actuating device clutch of the present utility model includes fixed seat 1, is arranged on the angle in fixed seat 1 Actuator 2, is arranged on the rotating shaft 3 on angle demodulator 2, is arranged on the swing seat 4 in rotating shaft 3, is arranged on the drivewheel on swing seat 4 5, and it is arranged on the driven pulley 6 in fixed seat 1, swing seat 4 is provided with the torsionspring 7 being connected with fixed seat 1.Fig. 1 (a) is Released state, Fig. 1 (b) is engagement state.

Angle demodulator 2 can be one of steering wheel, electromagnet mechanism or motor mechanism.Fig. 2 is angle demodulator 2 Embodiment for motor mechanism.

In the present embodiment, angle demodulator 2 by motor 21, the cam 22 of connection motor 21 rotor and is arranged in rotating shaft 3 Rocking arm 23 form.Fig. 2 (a) is released state, and Fig. 2 (b) is engagement state.

In the present embodiment, when needing to engage drivewheel 5 with driven pulley 6, motor 21 rotates, and band moving cam 22 rotates, convex Wheel 22 makes the related rotating shaft 3 of rocking arm 23 rotate an angle, and swing seat 4 is arranged in rotating shaft 3, thus swing seat 4 turning with rotating shaft 3 Move and swing an angle, so that the drivewheel 5 being arranged on swing seat 4 is adjusted to an ad-hoc location and contact with driven pulley 6； Meanwhile, drivewheel 5 is rotated and is rubbed with driven pulley 6, and frictional force makes drivewheel 5 engage with driven pulley 6；Now, motor 21 can stop Rotation stop is moved, and drivewheel 5 and driven pulley 6 continue to remain engaged with and be driven in the presence of frictional force, such as Fig. 2 (b) state.

In the present embodiment, when needing to separate drivewheel 5 with driven pulley 6, drivewheel 5 stops power output, makees in gravity With under, drivewheel 5 is separated with driven pulley 6, such as Fig. 2 (a) state.

In the present embodiment, rotating shaft 3 is also equipped with torsionspring 7, torsionspring 7 connection fixing base 1 and swing seat 4, reverses Spring 7 is used for mitigating the gravity from swing seat 4 and drivewheel 5 that rotating shaft 3 is born.

Drivewheel and driven pulley can be friction pulley or gear, and in the present embodiment, drivewheel 5 and driven pulley 6 are appearance The friction pulley of rubber layer is sheathed with face.

Introduce the workflow of actuating device clutch with reference to Fig. 3.

First, the need of joint, i.e. execution step s1, if necessary to joint, then execution step for drivewheel and driven pulley S2, angle demodulator makes the related swing seat of rotating shaft rotate an angle, so that drivewheel is contacted with driven pulley, actively rotates simultaneously Dynamic and with driven pulley friction, frictional force makes drivewheel engage with driven pulley.Now, angle demodulator can stop to drivewheel Active force, i.e. execution step s3.Drivewheel be rotated further and with driven pulley friction, i.e. execution step s4, frictional force makes drivewheel Remain engaged with driven pulley.

In engaging process, whether actuating device clutch receives detached signal, i.e. execution step s5.If needed To be separated, then execution step s6, drivewheel stops power output, and under gravity, drivewheel is separated with driven pulley.

Above-described embodiment only have expressed a kind of embodiment of the present utility model it is impossible to be interpreted as to this utility model patent The restriction of scope.It should be pointed out that for the person of ordinary skill of the art, conceive without departing from this utility model Under the premise of, some deformation can also be made and improve, such as drivewheel and the position of driven pulley exchange, made with spring drivewheel with from Driving wheel separation etc., these broadly fall into protection domain of the present utility model.
