Centrifugal clutch and drive system

Abstract

The invention provides a centrifugal clutch and a drive system. The centrifugal clutch comprise a driven wheel, a drive wheel, a centrifugal block, a friction plate and a reset spring, wherein one endof the driven wheel is sunken inward and forms a containing cavity, one end of the drive wheel is arranged in the containing cavity in a penetration mode, the side wall of the driven wheel and the side wall of the drive wheel are arranged at an interval, a guiding groove is formed in the driven wheel and distributed in the radial direction of the driven wheel, the centrifugal block is arranged inthe guiding groove in a sliding mode, the reset spring is connected with the centrifugal block and the drive wheel, and the friction plate is arranged at the top end of the centrifugal block. When the rotation speed of the drive wheel reaches a preset value, the centrifugal block stretches out of the guiding groove so as to drive the driven wheel to rotate through friction force between the friction plate and the side wall of the containing cavity. A heat dissipation bulge is arranged on the outer side of the driven wheel, and the heat dissipation bulge can increase the contact area between the driven wheel and air, and then releases heat generated by friction between the friction plate and the driven wheel to the air, and prevents the problem that temperature of the driven wheel is high,and therefore the friction plate is burnt down.

Description

technical field [0001] The invention relates to the technical field of transmission equipment, in particular to a centrifugal clutch and a drive system. Background technique [0002] Centrifugal clutches are used for power transmission or cut-off, and are more commonly used equipment in mechanical transmissions. [0003] In the prior art, the centrifugal clutch includes a driving wheel, a driven wheel, and a centrifugal block. One end of the driven wheel is recessed inward to form a housing chamber, which is cylindrical in shape. The center line of the housing chamber is collinear with the axis of the driven wheel. The driving wheel is connected to the driven device by transmission; the driving wheel is connected to the power source by transmission, the driving wheel is accommodated in the accommodation chamber, the axis of the driving wheel is set in line with the axis of the driven wheel; a chute is provided on the side wall of the driving wheel, and the centrifugal The b...
