Abstract
The invention discloses a forcible separation centrifugal pressure plate which comprises a pressure plate body, a driving part, a centrifugation body and a driven part and the like. A fixed block and a sliding block are arranged on the inner circle of 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. The sliding block is directly matched with the driven part in a mode of friction, or a friction disc is arranged on one side, close to the driven part, of the sliding block. A forcible traction mechanism capable of enabling the centrifugation body to move inward in the radial direction is arranged on the driving part or on a rotary shaft of the driving part. According to the forcible separation centrifugal pressure plate, 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 forcible separation centrifugal pressure plate further solves the problem that gear shifting is difficult to an engine in a high-speed running process.

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.
On the other hand, when shifting gears in the motor-driven vehicle going process, because power engine is in higher rotation speed, existing centrifugal clutch can not be disconnected, and causes the gearshift difficulty, in the situation that there is no cut-off clutch, transmission gear can be subject to loss.
