Forced separation centrifugal pressure plate

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.

Description

technical field [0001] The invention relates to the improvement technology of a motor vehicle clutch, in particular to a forced separation centrifugal pressure plate. Background technique [0002] The centrifugal clutch transmits torque through friction. When the driving part reaches the specified angular velocity, the centrifugal body is thrown out and pressed against the inner wall of the driven part, and is forced into motion by friction to transmit torque. Because the centrifugal force gradually increases with the increase of the speed, the use of the centrifugal clutch is equivalent to gradually adding the load to the prime mover, so that the working machine can be started directly, and the effect of smooth starting can be obtained. If the centrifugal clutch and the motor are directly connected drive, can significantly reduce the start-up current. Centrifugal clutches have some characteristics that other clutches do not have, so they are widely used in industry. [00...

AI Technical Summary

Problems solved by technology

[0003] However, the centrifugal clutch also has its own disadvantages: 1) The engagement of the clutch depends on the centrifugal force, so it cannot transmit a load greater than the rated torque

2) Since the centrifugal clutch force is proportional to the square of the rotational speed, and the output power changes with the cube of the operating rotational speed, it is not suitable for use in variable speed transmission systems

Centrifugal clutches should not be used on low-speed shafts. In order to achieve sufficient centrifugal force at low speeds, the structural size must be increased, which will increase the cost.

3) When the prime mover does not reach the rated speed, the centrifugal body will slip relative to the driven part, which will generate frictional heat and consume part of the energy. long place application

[0004] On the other hand, when shifting gears while the motor vehicle is running, because the power machine is at a relatively high speed, the existing centrifugal clutch cannot be disconnected, resulting in difficulty in shifting gears. If the clutch is not disconnected, the transmission gear will Suffering loss
