Abstract

The invented automatic clutch is composed of sheath, spring, shaft body, inertial wheel and is applied on engine to simplify the control system of general clutch. It uses flexibility body friction force to transfer torque and uses rotational inertia of inertial wheel to control the engine rotation speed change, the moment of rotation formed from angular acceleration controls the pull force of flexibility body friction, and it proceeds control, automatic on-off of the formation of flexibility body friction force. thereby controls the power-output.

Description

Automatic clutch
The invention belongs to the motor matching parts, be used to control power output.Especially the automatic clutch of forming by sheath, spring, axis body.
Once the spring clutch of using in the part motor driven starter was exactly a kind of in the automatic clutch, its main structure is made up of sheath, spring, main passive axis body, the running principle is: with tighter being enclosed within outside driving shaft and the driven axle of spring, by the frictional force transmitting torque that spring produces when rotating outside axle, be to use around one of form of gonosome frictional force.This clutch is in normal bonding state, power can't cut, only after engine start, produce when surmounting, spring skids outside axle and just separates, when skidding, spring inside diameter still is in Frotteurism between axial plane, control power output automatically so the clutch of this structure can not be applied to motor.
Task of the present invention solves spring clutch power exactly and can't cut, and can not be applied to motor and control power output problem automatically, and a kind of automatic clutch finally is provided for motor is supporting.
In order to achieve the above object, the scheme that the present invention adopts is: use around the gonosome tribology principle, and respective formula
Figure A9910976300031
Be foundation, after friction factor was determined, suitably increasing wrap angle sigma can increase
Figure A9910976300032
Ratio, so just can be with the bigger torque power output of less torque power control.Way is: a flying wheel is set, and change former clutch medi-spring axis body often is combined into normal separated state, sheath and spring head end are fixed on (as big flywheel) on the driving part, and be enclosed within outside the driven axle, leave the gap, spring end connects in flying wheel, and flying wheel is bearing on the driven axle by bearing.The principle of operation process is: by the engine throttle control rotation speed change, use the rotary inertia of flying wheel: I=mi 2, by the formed moment of rotation of variation of the relative spring head end of flying wheel angular velocity:
Figure A9910976300033
, the locking torque of control spring end: F 2r 0, implement the formation of opposing connection gonosome frictional force and control, be i.e. automatic clutch.Motor is at even rotating speed or when turning round under less negative angle acceleration rotating speed, the moment of rotation trend zero or the negative value of flying wheel, and at this moment the slack list locking torque of spring end rotates formed resisting moment: M by flying wheel relative to certain medium Z〉=F 2r 0Bear, guarantee that clutch reliably turns round.When (hanging up properly shelves) starting was quickened or turn round under even rotating speed, motor overcame the moment of inertia and the resisting moment acting of flying wheel, promptly is: M G+ M z〉=F 2r 0＞M T, spring is at F 1, F 2The following passive axis body of locking of effect, and produced around gonosome frictional force, clutch is combination.When (desire gear shift) subtracts throttle, when engine speed descended suddenly, the torque reserve energy of flying wheel under high rotating speed discharged again, and its moment of momentum acts on spring end, and flying wheel weakens relative to the resisting moment that medium rotates simultaneously, at this moment: M G+ M z＜M TBe moment of rotation (negative value) more than or equal to resisting moment, its summation is less than spring twist-tie combined stress moment M T, spring gets loose under opposite moment loading, disappears around gonosome frictional force, and clutch cuts off.
Flying wheel in the such scheme is the rotor of an alternator, and clutch is evenly turning round under the rotating speed, and the electromagnetic torque that the locking torque of spring end is rotated by the rotor relative stator is born.
Flying wheel in the such scheme can be the impeller in the blower fan, and clutch is evenly turning round under the rotating speed, and the locking torque of spring end rotates the resisting moment that forms by impeller relative to air and bears.
Flying wheel in the such scheme also can be a dozen oil tankers in the enclosed running, and clutch is evenly turning round under the rotating speed, and the locking torque of spring end rotates the resisting moment that forms by the wheel of buying oil relative to fluid and bears.
Flying wheel in the such scheme can also be that a cross that studs with centrifugal is taken turns, and clutch is turning round under even rotating speed, and when the locking torque of spring end was rotated by the cross wheel, centrifugal was rotated the resisting moment that produces the formation that rubs relative to brake drum and bear.
Because this programme adopts normal separated structures, the characteristic of fit applications flying wheel, by the engine throttle control rotation speed change, moment of rotation by angular acceleration control flying wheel, control that can be instant is around the formation of gonosome frictional force, also just controlled power output, and rotate formed resisting moment locking spring end relative to medium with flying wheel, can guarantee that clutch evenly working under the rotating speed reliably, this just controls power output automatically technical basis is provided for spring clutch is applied to motor, its application will be simplified the control system of modern general clutch, alleviate driving operation intensity, and can reduce the overall cost of equipment.
