The utility model discloses an automatic centrifugal platen type clutch which comprises a platen, a drive member, a centrifugation body and a driven member, a fixed block and a sliding block are arranged inside the platen, tapered openings are formed in the inner edge of the fixed block and in the inner edge of the sliding block, tapered protrusions are arranged on the outer edge of the centrifugation body, the tapered protrusions and the tapered openings can be mounted together in a matching mode, and the side, close to the driven member, of the sliding block is in frictional match with the driven member through a friction plate or is in match with the driven member directly. According to the automatic centrifugal platen type clutch, the radial pressure of the centrifugation body is changed into axial pressure, the pressure on a friction face is not changed easily, loads of large torque can be transferred, the clutch is hardly affected by speed change, and the problem that heat is generated out of friction needs not to be considered before the clutch reaches rated speed. Further, the automatic centrifugal platen type clutch is reasonable in structure, good in use effect and suitable for popularization and implement.
Description
Technical field
The utility model relates to automobile clutch improvement technology, is specifically related to a kind of centrifugal platen automatic clutch.
Background technique
Centrifugal clutch transmits moment of torsion by frictional force, and when driving link reached regulation angular velocity, centrifugal body was thrown out of with the driven member inwall and compresses, and is forced it to enter motion state and is transmitted moment of torsion by frictional force.Because centrifugal force is to increase gradually with the increase of rotating speed, so use centrifugal clutch just to be equivalent to little by little be added to load on prime mover, thereby can the across-the-line starting work mechanism, and the effect of acquisition smooth starting, if centrifugal clutch and motor are directly driven, can reduce inrush current significantly.Centrifugal clutch has the more unexistent characteristics of other clutch, so be widely used in industry.
Yet centrifugal clutch also has himself defective: 1) joint of clutch depends on centrifugal force, therefore can not transmit the load greater than rated torque.If the driven end overload is just clutch skids.2) since centrifugal clutch power be proportional to rotating speed square, therefore output power then will should not be used in variable ratio drive system with cube the changing of working speed.Centrifugal clutch also should not be contained on the lower velocity shaft and use, and advances in order to reach enough centrifugal force at low speed, will increase physical dimension, and cost will be increased.3) before prime mover does not reach rated speed, centrifugal body will skid with respect to driven member, thereby produces frictional heat, consumes part energy, therefore centrifugal clutch is not made in the occasion at Fraquent start and is used, and should not use in the oversize place of starting process yet.
The model utility content
The purpose of this utility model is the problem and shortage that exists at existing centrifugal clutch, and a kind of centrifugal platen automatic clutch is provided.
The utility model is achieved through the following technical solutions: a kind of centrifugal platen automatic clutch, comprise platen, driving link, centrifugal body and driven member, driving link rotating shaft and power engine rotating shaft are in transmission connection, driven member and load are in transmission connection, the radially-directed structure is set between centrifugal body and the driving link, spline is connected between described driving link and the driving link rotating shaft, described platen is fixed on the driven member, the inner ring edge of platen is provided with the slide block of a fixed block and a translation vertically, described fixed block and slide block inward flange arrange tapered opening, described centrifugal external edge is set to tapered protrusion, and this tapered protrusion and tapered opening can be installed togather; Be provided with friction disk at described slide block near driven member one side, described friction disk is sleeved in the driving link rotating shaft and with driving link rotating shaft spline and is connected; Described friction disk and driven member frictional fit.
Be provided with guide mechanism between described fixed block and the slide block, described guide mechanism comprises axially directed bar and guiding groove.
Be provided with friction ring between friction disk and driven member, described friction ring is fixed on the driven member inwall.
A kind of centrifugal platen automatic clutch, comprise platen, driving link, centrifugal body and driven member, driving link rotating shaft and power engine rotating shaft are in transmission connection, driven member and load are in transmission connection, the radially-directed structure is set between centrifugal body and the driving link, spline is connected between described driving link and the driving link rotating shaft, described platen is fixed on the driven member, the inner ring edge of platen is provided with the slide block of a fixed block and a translation vertically, described fixed block and slide block inward flange arrange tapered opening, described centrifugal external edge is set to tapered protrusion, and this tapered protrusion and tapered opening can be installed togather; Be provided with rubbing surface, described rubbing surface and driven member frictional fit at described slide block near driven member one side.
Be provided with guide mechanism between described fixed block and the slide block, described guide mechanism comprises axially directed bar and guiding groove.
Be provided with friction ring between rubbing surface and driven member, described friction ring is fixed on the driven member inwall.
The utlity model has following advantage: the utility model can also improve the performance of existing centrifugal clutch when having the centrifugal clutch advantage.Mainly show as: 1) frictional force of existing centrifugal clutch is the friction that simple radial pressure produces, and can not transmit the load greater than rated torque, if the driven end overload, just clutch would skid.And the utility model changes radial pressure into axial pressure, rubs to be axial rub, and it is less that the size of axial pressure is influenced by rotating speed, but is subjected to centrifugal external edge tapering to influence bigger.Under specific rotation speeds, the centrifugal jack-up slide block that outwards moves makes its axial translation.Centrifugal outer peripheral tapering hour, centrifugal moves radially distance and axial pressure is big, and the slide block under the tapered protrusion effect is not easy return, thereby the pressure of rubbing surface is not easy to change, guarantee the characteristics that frictional force is bigger and stable, load that can transmitting large torque; 2) rubbing surface of existing centrifugal clutch is directly produced by radial pressure, so be subjected to the velocity variations factor affecting bigger, and the utility model clutch is subjected to the velocity variations factor affecting very little, as long as on rated speed, centrifugal is in amphi position end, axial pressure almost changes not quite, so this clutch is influenced by speed change hardly; 3) the utility model does not almost have resistance between slide block and the centrifugal body in start-up course, so hardly with the frictional heat problem of considering before arriving rated speed.The improved clutch configuration of the utility model is reasonable, makes easily or transforms, and is easy to use, effective, is beneficial to very much promotion and implementation.
