Problems solved by technology

[0002] The existing automatic clutches are mainly dry type and oil bath type; the dry type automatic clutch is mainly centrifugal type, which only relies on centrifugal force to open the friction plate, so slippage will occur when outputting high torque at low speed, and the friction plate will continue to heat up , which reduces the service life of the clutch, and the effective area of ​​the friction plate is small, and the transmission capacity is poor; while the oil-bath automatic clutch has a complex structure, high cost, and low service life, and subsequent maintenance is inconvenient

Abstract

The invention discloses an automatic dry-type centrifugal roller torque force clutch. The clutch comprises a cam, a fixed seat and a plurality of slide block components, wherein the cam is arranged in a position close to the middle of the fixed seat; the slide block components are respectively arranged around the cam; and each slide block component comprises a slide block, a friction plate, a fixed arm and a return spring, wherein the slide block is arranged on the fixed seat, the friction plate is arranged on the slide block, the fixed arm is arranged on the fixed seat, the return spring is arranged between the slide block and the fixed arm, and a plurality of lug bosses are arranged on the cam. According the clutch, the cam is used for ejecting the slide blocks to enable the friction plates to be combined with an external power output component, the larger is a load, the larger is the binding force, so that the slip phenomenon is prevented at a low speed and large torque condition; the large-area contact of the friction plates and the external power output component prevents the external power output component from distorting due to continue single-side stress; and rollers can be arranged on the cam to prevent the cam from abrading, so that the work efficiency is improved, the slip frequency is reduced, and the service life of the clutch is increased.

Description

technical field [0001] The invention relates to an improvement of an automatic clutch, in particular to a dry type centrifugal roller torsion automatic clutch with simple structure, high efficiency and long service life. Background technique [0002] The existing automatic clutches are mainly dry type and oil bath type; the dry type automatic clutch is mainly centrifugal type, which only relies on centrifugal force to open the friction plate, so slippage will occur when outputting high torque at low speed, and the friction plate will continue to heat up , which reduces the service life of the clutch, and the effective area of ​​the friction plate is small, and the transmission capacity is poor; while the oil-bath automatic clutch has a complex structure, high cost, and low service life, and subsequent maintenance is inconvenient. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a dry cen...
