Abstract
The invention discloses a centrifugal pressure plate automatic clutch which comprises a pressure plate, a driving part, a centrifugation body and a driven part. A fixed block and a sliding block are arranged in the pressure plate. A cone-shaped opening is formed in the inner edges of the fixed block and the sliding block. The outer edge of the centrifugation body is arranged to be a cone-shaped protrusion. The cone-shaped protrusion and the cone-shaped opening can be arranged together in a matching mode. One side, close to the driven part, of the sliding block is matched with the driven part in a mode of friction through a friction disc or is directly matched with the driven part in the mode of friction. According to the centrifugal pressure plate automatic clutch, radial pressure of the centrifugation body is converted to axial pressure, pressure of a friction surface is enabled not to be changed easily, load with large torque can be transmitted, influence of speed changing is almost avoided, and the problem of friction heating before reaching rated rotating speed is almost not considered. The centrifugal pressure plate automatic clutch is reasonable in structure, and good in using effect, and can be popularized and implemented conveniently.
Description
Technical field
The present invention relates to automobile clutch improvement technology, be specifically related to a kind of centrifugal platen automatic clutch.
Background technique
Centrifugal clutch comes transmitting torque 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 forces it to enter motion state and transmitting torque 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 significantly inrush current.Centrifugal clutch has the unexistent Some features 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) due to centrifugal clutch power be proportional to rotating speed square, output power will with cube the changing of working speed, therefore should not be used in variable ratio drive system.Centrifugal clutch also should not be contained on 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.
Summary of the invention
The objective of the invention is the problem and shortage for existing centrifugal clutch existence, a kind of centrifugal platen automatic clutch is provided.

Be provided with friction ring between rubbing surface and driven member, described friction ring is fixed on the driven member inwall.
The present invention has the following advantages: the present invention can also improve the performance of existing centrifugal clutch when having the centrifugal clutch advantage.Main manifestations is: 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 present invention changes radial pressure into axial pressure, rubs to be axial rub, and the size of axial pressure is subjected to influence of rotation speed less, but is subjected to centrifugal external edge tapering to affect larger.Under specific rotation speeds, the centrifugal-block jack-up slide block that outwards moves makes its axial translation.The outer peripheral tapering of centrifugal-block hour, centrifugal-block moves radially distance and axial pressure is large, 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 larger and stable, load that can transmitting large torque; 2) rubbing surface of existing centrifugal clutch is directly produced by radial pressure, so it is larger affected by the velocity variations factor, and clutch of the present invention is subjected to the velocity variations factor to affect very little, as long as on rated speed, centrifugal-block is in amphi position end, axial pressure almost changes not quite, so this clutch is affected by speed change hardly; 3) the present invention in start-up course, does not almost have resistance between slide block and centrifugal body, so hardly with the frictional heat problem of considering before arriving rated speed.The improved clutch configuration of the present invention is reasonable, easily makes or transformation, and is easy to use, effective, is beneficial to very much promotion and implementation.
