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

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 [0001] The invention relates to the improvement technology of a motor vehicle clutch, in particular to a centrifugal pressure plate automatic clutch. 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...
