Problems solved by technology

[0002] The existing centrifugal clutch uses two centrifugal blocks connected by a spring, and the inner and outer sides of the two centrifugal blocks are respectively provided with a driving shell and a passive shell. At this time, the centrifugal block leans against the active hub under the tension of the spring, and is out of contact with the passive hub, and cannot transmit power. until the friction plate on the centrifugal block is pressed against the inner wall of the passive hub, and the power of the driving shaft is transmitted to the passive hub. The torque transmitted by the existing mechanism is closely related to the contact pressure between the friction material and the passive hub. The existing structure has the following problems: 1. When the speed of the driving shaft is constant, the contact pressure is a constant value. When the load torque exceeds the contact pressure, the friction plate and the passive hub will slip and wear quickly; 2. When the speed of the driving shaft is constant , the friction material wears, which is equivalent to increasing the spring tension, and the increase part offsets the same amount of centrifugal force, so that the contact pressure is reduced, the friction plate and the passive hub slip, and the wear is rapid

Embodiment 1

[0012] Embodiment 1, a kind of one-way self-energizing type centrifugal clutch, refer to figure 1 , the outer circumference of the active shell 4 is evenly provided with lugs 6, each lug 6 is provided with a joint socket 7, and the joint head 8 provided at one end of the centrifugal block 1 is movably installed in the joint fossa 7, and the spring 3 The two ends of the centrifugal block 1 and the bump 6 are respectively fixed on the outer side of the centrifugal block 1. The friction plate 2 is fixed, and the passive shell 5 is surrounded by the centrifugal block 1. When it is at rest, the spring 3 is in a compressed state. The centrifugal block 1 and the passive A gap is formed between the shells 5, and the number of the bumps 6 can be set as required. In this embodiment, three bumps 6 are used, which constitutes a structure of the present invention.

Embodiment 2

[0013] Embodiment 2, a kind of one-way self-energizing type centrifugal clutch, refer to figure 1 , on the basis of Embodiment 1, two springs 3 fixed on the centrifugal block 1 and the protruding block 6 are arranged side by side, and the others are identical to Embodiment 1.

Abstract

The invention discloses a unidirectional servo-type centrifugal clutch which consists of a centrifugal block, a friction sheet, a spring, a driving hub and a driven hub. The unidirectional servo-type centrifugal clutch is characterized in that the outer circumference of the driving hub is uniformly provided with lugs at intervals; each lug is provided with an articular pan; one end of the centrifugal block is provided with an articular head which is movably installed on the articular pans; and two ends of the spring are respectively fixed on the centrifugal block and the lugs. The unidirectional servo-type centrifugal clutch disclosed by the invention has the characteristics of stable joint, difficulty in sliding, extremely small abrasion, and longer service life.

technical field [0001] The invention belongs to the technical field of clutches, in particular to a one-way self-energizing centrifugal clutch. Background technique [0002] The existing centrifugal clutch uses two centrifugal blocks connected by a spring, and the inner and outer sides of the two centrifugal blocks are respectively equipped with a driving shell and a passive shell. At this time, the centrifugal block leans against the active hub under the tension of the spring, and is out of contact with the passive hub, and cannot transmit power. until the friction plate on the centrifugal block is pressed against the inner wall of the passive hub, and the power of the driving shaft is transmitted to the passive hub. The torque transmitted by the existing mechanism is closely related to the contact pressure between the friction material and the passive hub. The existing structure has the following problems: 1.
