Description
Technical field
The invention belongs to mechanical power transmission field, is filled more particularly to the clutch in a kind of disengaging type power output device
Put.
Background technology
Chinese invention patent application（CN1686755A）In disclose a kind of gear speed changer for bicycle and man power tricycle.Should
Speed changer is to complete speed change with gear combination of different sizes is changed, so must have splined shaft and spline gear in design,
Splined shaft and spline gear need good fit clearance, it is desirable to standard clearance to be moved freely under coordinating and be not obstructed.By
In spline gear, the size of splined shaft is smaller, needs to cut technology with line when manufacturing, and can be only achieved preferable effect.Power output
Device is the critical piece in speed changer, it is the technology of most critical in design, and the original which plays car is fast, various after speed change
The effect transmitted outside internal force, the size of the part also directly affect speed changer overall dimensions, and the relation between them is directly proportional.Power
Output device should not be too large, too big to influence beautiful and installation, can not size, size torsion is inadequate.The part great advantage be with
Main shaft is concentric, it can be rotated synchronously with main shaft, can also be with main shaft asynchronous rotary, so as to reduce gearbox volume, institute
Preferably can not arbitrarily it change by former design size during manufacturing.The shifting fork spring number of turns in speed changer should be lacked, and elasticity will be got well,
It not only plays the effect of gear return, but also plays the positioning action of gear.
This power output device is complicated, it is impossible to is well adapted for the conductance calls to power.
The content of the invention
To overcome drawbacks described above, the technical problem to be solved in the invention：A kind of clutch dress on power take off is provided
Put, which can be well adapted for the conductance calls to power, and controllability is good.
To solve the technical problem, technical scheme：Arrangement of clutch on a kind of power take off, for setting
Put on the power take off of gear shifting type, power take off includes power input shaft, is rotationally covered on power input shaft
It is connected to high speed driving gear, it is characterised in that driving member is circumferentially fixedly provided with high speed driving gear, on power input shaft
Drive sleeve is socketed with gap, and multi-disc friction piece is equipped between drive sleeve and driving member；Electromagnet is equipped with the outside of drive sleeve,
For, by promoting drive sleeve friction plate is pressed together with driving member, and then making power automatic successively after electromagnet is powered
Power input shaft is transmitted on driving member by drive sleeve, friction plate.
Electromagnet can produce magnetic field after being powered, and promote corresponding actionable component actuation to compress friction plate by magnetic field
Realize that power changes road conduction together.Electromagnet can be by the side that is electrically connected with velocity sensor, controller, manual switch
Formula, whether to realize the energization of electromagnet.Such as apply on electric car, reach setting from low speed in the gait of march of electric car
During value, or by the size of controller for electric vehicle sensory current electromagnet is controlled to be powered.And by drive sleeve to friction
Piece is compressed, and realizes the switching of power conduction route.Drive sleeve can be that band is magnetic or inside electromagnet in itself
Itself there is actionable component, promote drive sleeve to be pressed together friction plate by the actionable component.Electromagnet can be with
It is whether being operated with manual switches to be powered to realize, user can be according to actual conditions, voluntarily to determine the need for switching transmission
Pattern.
The truncation surface of the driving member is in Qian shape, and the openend of the driving member is located at driving member towards electromagnet, friction plate
It is interior.The driving member is provided with, a restriction effect can be carried out to these friction plates so that the job stability of friction plate
It is good.
High speed driving gear is equipped with week towards on the end face of driving member integrally formed with coupling tunnel, the closed end of driving member
To the running-on being regularly socketed on coupling tunnel.This facilitate that coupling between driving member and high speed driving gear, is easy to implement
Stable transmission.
It is axially arranged with some slots along it on the wall body of driving member, is integrally formed with a gap in the outer rim of friction plate
The plug being plugged in slot.The setting of slot and plug, further ensures the stability of friction plate.
Some convex bodys are provided with the position of drive sleeve on the outer circumferential surface of power input shaft, these convex bodys are defeated in power
Enter and extended spirally in the same direction on the outer circumferential surface of axis, be equipped with drive sleeve and be used for and the groove of convex body clearance fit, groove and convex body
Trend is consistent；Groove and convex body are used to make drive sleeve be locked at power input shaft in drive sleeve pressing friction piece.In electromagnetism
When iron carries out drive sleeve axial promote, the rotation of power input shaft in addition, and to coordinate between convex body and groove, and finally
Drive sleeve is set tightly to be locked together with power input shaft.When reaching stabilized speed, drive sleeve is consistent with the rotating speed of power input shaft,
Drive sleeve rotates backward relatively with that will not occur on power input shaft, is locked together between drive sleeve and power input shaft, because
This for a long time need not be powered electromagnet, can effectively reduce energy consumption.And when external resistance is big, or motor speed is by people
During to reduce, power input shaft is reduced due to rotating speed so that drive sleeve makees counteragent equivalent to opposite power input shaft so that
Unlocked between drive sleeve and power input shaft, and realize the switching route conduction of power.
Longitudinal truncation surface of drive sleeve is L-shaped, and friction plate is socketed in drive sleeve.This causes drive sleeve to be easy to friction plate
Crimping, and also be adapted for drive sleeve and it is following promote set between transmission coordinate.
The promotion set being socketed on power input shaft is equipped between electromagnet and drive sleeve, promotes set towards drive sleeve
Integrally formed with ring flange on end face.Middle transition part of the set as thrust is promoted, facilitates promotion of the electromagnet to drive sleeve,
And it is simple in structure, functional reliability is good.
Electromagnet includes coil and the columnar iron core in coil radial extension, and the periphery of coil is surrounded by annular
Iron ring, iron core are equipped with the collar extension for promoting set gap grafting towards the interior oral area promoted on set end face.This electromagnet structure letter
It is single, it is capable of the stable delivery of convenient electromagnetic iron axial thrust.
Therefore, beneficial effects of the present invention：Electromagnet is used in this arrangement of clutch, can be passed through in gearshift procedure is carried out
The energization of electromagnet produces axial thrust, and make it that gear shift is smoothly realized so that the controllability of power output device is good, energy
It is enough well corresponding mechanical equipment to be operated under suitable working status, it can either meet actual need of work, and energy
It is enough effectively to save energy consumption.By setting multi-disc friction piece so that power take off friction plate in gearshift procedure is gradually compacted,
And cause two grades between there is certain transitional function, gear shift is gentle, will not make mechanical equipment have during the work time generation it is bright
Aobvious gear shift performance.
