Lever centrifugal clutch

Abstract

The invention discloses a lever centrifugal clutch comprising a driving disc, at least two centrifugal mechanisms and a driven disc. Each centrifugal mechanism comprises a centrifugal member, a deformed lever and a tensions spring and further comprises a positioning post. Each positioning post is movably sleeved with one end of the centrifugal member of one centrifugal mechanism and one end of the deformed lever on the adjacent centrifugal mechanism sequentially from bottom to top. Each tension spring allowing the deformed bars to return is disposed between every two adjacent deformed levers. The deformed levers are overlap-fastened to the centrifugal members by means of fitting of grooves and tongues and apply forces to the centrifugal members. As each centrifugal mechanism comprises only one positioning post, the structure of the driving disc is simplified, the manufacturing process is simplified, the production cost is lowered, the structure of the clutch is simplified, mounting and demounting are facilitated, maintenance cost is lowered, and workload is reduced for workers; shockproof washers are provided on the centrifugal members and the deformed levers, shocking of the clutch is avoided, noise is reduced, and the service life of the clutch is prolonged.

Description

technical field [0001] The invention relates to a clutch, in particular to a lever centrifugal clutch. Background technique [0002] The existing centrifugal automatic clutch has a basic structure consisting of a driving part, a centrifugal body, a driven part and a tension spring. Transmission torque (power), when the speed is lower than the set speed (starting speed), the centrifugal body is pulled back by the return spring, the centrifugal body is completely separated from the friction disc, and the contact (power) is broken. In actual use, this centrifugal clutch will be subjected to the action of the return spring all the time, and the power loss is relatively serious. To overcome the above deficiencies, reduce power loss. In addition, in some cases where the engine speed is low, such as a tiller, the tiller cannot be used normally. For this reason, I have designed a lever centrifugal clutch, which has applied for an invention patent. The name: "Lever centrifugal clu...

Problems solved by technology

In addition, in some cases where the engine speed is low, such as a tiller, the tiller cannot be used normally. For this reason, I have designed a lever centrifugal clutch, which has applied for an invention patent. The name: "Lever centrifugal clutch "(application number: 201310402196.2)

[0003] In view of the above-mentioned structure in the previous invention patent that "each group of cylinders includes a centrifuge positioning column and a special-shaped lever positioning column, the centrifuge positioning column is close to the edge, and the special-shaped lever positioning column is arranged inside the centrifuge positioning column", In practical application and production, the structure is complicated, the processing is difficult, the material requirements are high, and the interaction between the special-shaped lever and the centrifuge produces vibration during the movement process, which will damage the performance and service life of the product.
