Centrifugal clutch

Abstract

The invention provides a centrifugal clutch. The centrifugal clutch comprises an inner ring piece connected with a driving end, an outer ring piece connected with a driven end and a centrifugal assembly arranged between the inner ring piece and the outer ring piece. The inner ring piece and the outer ring piece are coaxially arranged, the centrifugal assembly is in transmission connection with the inner ring piece all the time, and after the inner ring piece rotates to reach the centrifugal condition, the centrifugal assembly can be triggered to be in transmission connection with the outer ring piece at the same time, so that clutch operation between the inner ring piece and the outer ring piece is achieved; a shell part is arranged between the inner ring part and the outer ring part; the outer shell pieces cover the two outer side end faces respectively so that a closed inner containing cavity can be formed between the inner ring piece and the outer ring piece, liquid injection openings communicated with the inner containing cavity are formed in the outer shell pieces, and the centrifugal assembly is arranged in the inner containing cavity filled with lubricating liquid. In addition, friction, heat transfer and the like generated in the frequent joint movement process of the centrifugal assembly can be filled with the lubricating liquid through the inner containing cavity defined by the outer shell part to provide lubricating fit, and the clutch operation effect of a centrifugal mode is remarkably improved.

Description

technical field [0001] The present invention relates to the technical field of clutches, and in particular, to a centrifugal clutch. Background technique [0002] Existing clutches, especially one-way clutches, generally have two movement modes, one is torque transmission or engagement, and the other is idling or overrun. Its function is that when the power source drives the passive element, it can only transmit in one direction. If the power source changes direction, such as clockwise to counterclockwise, it will automatically disengage and slip, so that no power transmission function is generated. One-way clutches are used in various fields, such as chain drives of bicycles, starting of automobiles, automatic transmissions, and so on. [0003] At present, the commonly used one-way clutches are usually friction type one-way clutches, which are mainly in the form of friction plates, so that they have high requirements on the environment and working conditions of use.

AI Technical Summary

Problems solved by technology

Because the temperature is too high or the temperature is too low, the friction coefficient of the friction plate will be affected, and the friction plate will easily slip and generate heat when it comes into contact with water or oil, which will affect the clutch effect.

In particular, the friction plate clutch for high torque occasions needs to be particularly bulky, resulting in many limitations

In addition, the sprag-type one-way clutches on the market, frequent clutch operations lead to greater wear and tear on the clutch elements, and are prone to abnormal noise, which is extremely inconvenient to operate
