Description
Technical field
The present invention relates to automobile clutch improvement opportunity, be specifically related to a kind of pressure and be separated centrifugal pressure plate.
Background technique
Centrifugal clutch carrys out transmitting torque by frictional force, and when driving link reaches regulation angular velocity, centrifugal body is thrown out of and compresses with driven member inwall, forces it to enter motion state and transmitting torque by frictional force.Because centrifugal force increases gradually with the increase of rotating speed, so use centrifugal clutch to be just equivalent to load to be little by little added on prime mover, thus can across-the-line starting work mechanism, and obtain the effect of smooth starting, if by centrifugal clutch and motor Direct driver, inrush current can be reduced significantly.Centrifugal clutch has the unexistent Some features of other clutch, so be widely used in the industry.
But centrifugal clutch also has himself defect: 1) joint of clutch depends on centrifugal force, the load being greater than rated torque therefore can not be transmitted.If driven end overloads, clutch just skids.2) due to centrifugal clutch power be proportional to rotating speed square, output power then will with working speed cube and change, therefore should not use in variable ratio drive system.Centrifugal clutch also should not be contained on lower velocity shaft and use, and entering to reach enough centrifugal force, will increase physical dimension at low speed, and cost will be made to increase.3) before prime mover does not reach rated speed, centrifugal body will skid relative to driven member, thus produces frictional heat, consumes part energy, therefore centrifugal clutch is not made and is used in the occasion at Fraquent start, should not apply in the place that starting process is oversize yet.
On the other hand, when carrying out gearshift position in motor-driven vehicle going process, because power engine is in higher rotation speed, existing centrifugal clutch can not be disconnected, and cause gearshift difficulty, when not having cut-off clutch, transmission gear can be subject to loss.
Summary of the invention
The object of the invention is for existing clutch Problems existing and deficiency, provide a kind of pressure to be separated centrifugal pressure plate.
The present invention is achieved through the following technical solutions: a kind of pressure is separated centrifugal pressure plate, comprise platen, driving link, centrifugal body and driven member, driving link rotating shaft is connected with power engine rotating shaft transmission, driven member is connected with load transmission, radially-directed structure is set between centrifugal body and driving link, spline joint between described driving link and driving link rotating shaft, described platen is fixed on driven member, the inner ring edge of platen is provided with a fixed block and one can the slide block of translation vertically, described fixed block and slide block inward flange arrange tapered opening, described centrifugal outer rim is set to tapered protrusion, this tapered protrusion and tapered opening can be installed togather, described slide block directly and driven member frictional fit, or is provided with friction disk at slide block near driven member side, described friction disk to be sleeved in driving link rotating shaft and with driving link rotating shaft spline joint, described friction disk and driven member frictional fit, driving link or driving link rotating shaft are provided with and can make the radially inner pressure draw-off mechanism of centrifugal body.
Between friction disk and driven member, be provided with friction ring, described friction ring is fixed on driven member inwall.
Described fixing between fast and slide block is provided with guide mechanism, and described guide mechanism comprises axially directed bar and guiding groove.
Described pressure draw-off mechanism is on driving link, arrange fulcrum one, a hinged L-type fork on fulcrum one, the hinged radial pull bar in one end of this L-type fork, the hinged axial pull bar of the other end of L-type fork, end and the centrifugal body of described radial pull bar are hinged, and the end of described axial pull bar is connected with pushing mechanism.
Described pushing mechanism be in driving link rotating shaft, be set with one can the push-plate one of axial translation, the outside of described push-plate one is provided with thrust-bearing, and the outside of described thrust-bearing is connected with axial actuating mechanism.
Between described push-plate one and driving link rotating shaft, spline is installed.
Described driving link is provided with groove, and described L-type fork and fulcrum one thereof are positioned at groove.
Described pressure draw-off mechanism overlaps intrinsic outer sleeve in driving link rotating shaft, on outer sleeve, radial direction is provided with strut, strut end arranges fulcrum two, a hinged J type fork on fulcrum two, the hinged radial pull bar in one end of this J type fork, end and the centrifugal body of described radial pull bar are hinged, the arranged outside pushing mechanism of described J type fork.
Described pushing mechanism comprises the push-plate two that is sleeved on also energy axial translation in driving link rotating shaft, and the outside of described push-plate two is provided with thrust-bearing, and the outside of described thrust-bearing is connected with axial actuating mechanism.
Described axial actuating mechanism is hydraulic driving, or is pneumatic drive, or is motorized motions.
The present invention has the following advantages: the present invention, while having centrifugal clutch advantage, can also improve the performance of existing centrifugal clutch.Main manifestations is: 1) frictional force of existing centrifugal clutch is the friction that simple radial pressure produces, and can not transmit the load being greater than rated torque, if driven end overload, clutch just skids.And radial pressure is changed into axial pressure by the present invention, rub as axial rub, the size of axial pressure is less by influence of rotation speed, but larger by centrifugal outer rim tapering effect.Under specific rotation speeds, the centrifugal-block jack-up slide block that outwards moves makes its axial translation.When the outer peripheral tapering of centrifugal-block is less, centrifugal-block moves radially distance and axial pressure is large, and the slide block under tapered protrusion effect is not easy return, thus the pressure of rubbing surface is not easy to change, guarantee the feature that frictional force is larger and stable, can the load of transmitting large torque; 2) rubbing surface of existing centrifugal clutch is directly produced by radial pressure, so affect larger by rate variance factor, and clutch of the present invention affects very little by rate variance factor, as long as on rated speed, centrifugal-block is in amphi position end, axial pressure almost changes not quite, so this clutch affects by speed change hardly; 3) the present invention is in start-up course, does not almost have resistance between slide block and centrifugal body, so hardly with considering arrive the frictional heat problem before rated speed; 4) the present invention can realize forcing the object of cut-off clutch, thus solves the problem of not easily shifting gears in high engine speeds operation process, and overcomes the gearshift of high engine speeds operation process and cause dysgenic problem to speed changer.
