Description
Technical field
The utility model is related to the clutch field of farm machinery, and in particular to a kind of jaw clutch.
Background technology
Existing clutch has the process of a gradual change, by rubbing for friction plate in transmission and connection transmission process is disconnected
Wipe power to realize the function of clutch, coordinate to realize the function of clutch also by gear and gear ring, two ways makes
After over time, the frictional force of friction plate reduces, and it is unreliable to control, the cooperation of gear and gear ring also easy slip teeth.
In field of agricultural machinery, the control to farm machinery needs fast response time, and the cost of clutch can not be too high,
Volume is difficult excessive, therefore needs a kind of a kind of clutch that can adapt to farm machinery, to meet fast response time, small volume,
Requirement simple in construction, the cost of active control unit.
Utility model content
The utility model in view of the shortcomings of the prior art, proposes a kind of simple in construction, small volume, fast response time tooth
Embedded-type clutch, concrete technical scheme is as follows：
A kind of jaw clutch, including driving disc spacing pressing, clutch plate and shift fork, the driving disc spacing pressing and the clutch plate are coaxial
Line；
The clutch plate one side is matched with the driving disc spacing pressing by draw bail, and the draw bail includes screens bolt and card
Position hole, the screens bolt and the screens hole, which coordinate, makes the drive connection or disconnection of the driving disc spacing pressing and the clutch plate, institute
State screens bolt and screens hole opposition is set, the screens bolt and screens hole matching；
The clutch plate another side is provided with screens seat, and the screens seat is cylindrical shape；
The screens seat and the clutch plate are connected in output shaft, the screens seat and the clutch plate by the way that spline is dynamic
It is fixedly connected, annular groove, the annular groove and screens seat coaxial line is provided with the screens seat；
The shift fork output end is matched with the annular groove.
Pass through the cooperation in screens bolt and screens hole so that when disconnecting transmission and connection transmission, can make an immediate response, and it is disconnected
Open and connect reliable, excessive heat, situation about will not also slip will not be produced because of friction.Annular groove enables to card
Position seat is when rotating, and shift fork is placed in annular groove, will not be collided, reliability gets a promotion, while the end of shift fork also can
Enough displacement of the control screens seat on output shaft effectively.
Further limit, the screens bolt there are four, and the screens bolt is rounded to be arranged at equal intervals.
Screens bolt and the alignment of screens hole are more easy.
Further limit, the shift fork includes control-rod, shifting part and return unit；
The control-rod includes the first lever and the second lever, and first lever is with second lever into 90 degree -120
Spend angle；
Described shifting part one end is fixedly connected with second lever, and the shifting part other end is provided with card column, the card
Post is fixedly connected with the shifting part, the card column and annular groove matching.
It is simple in construction, it is easy to control, in the strong applicability of farm machinery.
Further limit, the return unit is return spring, and it is straight that the return spring includes spire, first straight line portion and second
Line portion, the first straight line portion and the second straight line portion are located at the two ends of the spire, and the spire is enclosed on described the
In two levers, second straight line portion end is enclosed in first lever.
The displacement in first straight line portion is limited by the housing of clutch, and when the first lever is rotated, second straight line portion is rotated, multiple
Position spring stores power, when the external force of the first lever disappears, the first lever return.
Further limit, the shifting part is circular shape.
Convenient and screens seat coordinates, and prevents mutual interference.
Further limit, the card column is parallel with second lever.
Card column is more preferable to the transmission effect of the power of screens seat.
Further limit, the shifting part and the second lever junction are provided with sleeve, and the sleeve is solidly set on described
In second lever, the shifting part is fixedly connected with the sleeve.
So that the connection of shifting part and the second lever is more consolidated, while the also enhanced convenience in assembling.
The workflow of the technical program is that power output shaft transmits power to driving disc spacing pressing, and driving disc spacing pressing passes through draw bail
Coordinate transmission power to clutch plate, slided by fork controls clutch plate on output shaft, it is main when snib and the cooperation of screens hole
Moving plate and clutch plate connection, drive connection；When snib and screens hole depart from, driving disc spacing pressing and clutch plate are non-interference, and transmission is disconnected
Open.
The operation principle of shift fork is：The first lever is rotated, the first lever drives the second lever to rotate, and shifting part follows second
Lever is rotated, and the card column of the end of shifting part rotates with shifting part, the return in the presence of return spring, and shifting part carrys out backswing
It is dynamic, clutch plate is driven in the upper slip of output using card column.
The beneficial effects of the utility model are：Simple in construction, control response is fast and control is reliable, small volume.
