Problems solved by technology

[0007] However, in the centrifugal clutch described in the above-mentioned Patent Document 1, the clutch weight gradually comes into frictional contact with the clutch cover as the engine speed increases, so there is a problem that the time from when the engine speed starts to increase until the clutch is in the connected state is relatively short. Longer and lower fuel consumption, and smaller clutch capacity
On the other hand, in the centrifugal clutch described in the above-mentioned Patent Document 2, the drive plate rotated by the rotation of the engine is composed of two pieces, such as the first drive plate and the second drive plate, so the structure is complicated due to the increase in the number of parts. problem of increased manufacturing burden

Embodiment Construction

[0058] One embodiment of the centrifugal clutch according to the present invention will be described below with reference to the drawings. figure 1 It is a top sectional view schematically showing the configuration of the power transmission mechanism 100 including the centrifugal clutch 200 of the present invention. again, figure 2 By figure 1 A side view of the centrifugal clutch 200 is shown on line 2-2. The power transmission mechanism 100 including the centrifugal clutch 200 is a mechanical device that is installed between the engine and the rear wheels as drive wheels mainly in a motorcycle such as a scooter, and automatically changes the speed reduction ratio with respect to the number of revolutions of the engine. Transmit or block the rotational driving force on the rear wheel.

Abstract

Provided is a centrifugal clutch capable of increasing clutch capacity by using a simple configuration. The centrifugal clutch 200 comprises a drive plate 210 that has direct rotation drive as a result of the drive force of an engine. The drive plate 210 comprises both a swing support pin 214 and a guide section 216. The swing support pin 214 is fitted into a pin sliding hole 221 formed in a clutch weight 220 and swingably supports the clutch weight 220. The guide section 216 extends inclined towards the rear and outwards, in the rotation drive direction of the drive plate 210, is formed in anotched or hole shape, and has a protruding body 224 on the clutch weight 220 being in contact therewith. The pin sliding hole 221 is formed in a long hole shape that allows displacement of the clutchweight 220 towards the rear side in the rotation drive direction of the drive plate 210. The protruding body 224 is formed protruding from the clutch weight 220.

Description

technical field [0001] The present invention relates to a centrifugal clutch, which blocks the transmission of the rotational driving force to the driven side before the engine reaches a predetermined number of rotations, and transmits the rotational driving force to the driven side when the engine reaches the predetermined number of rotations. Background technique [0002] Conventionally, in motorcycles, lawnmowers, etc., a centrifugal clutch is used that transmits rotational driving force to the driven side when the engine reaches a predetermined number of revolutions. For example, the following patent document 1 discloses a centrifugal clutch in which the clutch counterweight disposed on one drive plate gradually displaces toward the clutch housing side as the engine speed increases, and the clutch shoe disposed on the clutch counterweight shifts toward the clutch housing. Frictional contact with clutch weight. In addition, the following patent document 2 discloses a cen...
