Problems solved by technology

[0006] However, in the centrifugal clutch described in the above-mentioned Patent Document 1, the connecting spring is connected to the substantially central portion of the clutch weight extending in the circumferential direction of the second drive plate, so a connecting spring having a strong elastic force (tension) is required. To limit the displacement of the clutch counterweight in the centrifugal direction, it is difficult to ensure the required clutch capacity (the power transmitted by the clutch) and the device structure is enlarged.

Embodiment Construction

[0029] Below, while referring to the attached Figure 1 One embodiment of the centrifugal clutch according to the present invention will be described. figure 1 It is a plan sectional view schematically showing the structure of the centrifugal clutch 100 according to the present invention. in addition, figure 2 for display from figure 1 A partially cutaway side view of the internal structure of the centrifugal clutch 100 is shown on the 2-2 line. The centrifugal clutch 100 is mainly installed between the engine and the rear wheel of the drive wheel in a motorcycle such as a scooter, and is a mechanism that transmits the rotational driving force of the engine to the rear wheel or blocks the rotational driving force of the engine. device.

Abstract

The present invention relates to a centrifugal clutch (100) provided with a drive plate (110) directly rotated and driven by the drive force of an engine, the drive plate (110) being provided with a rocking support pin (113) having a clutch shoe (123) and supporting the clutch shoe (123) so that the clutch shoe (123) will rock relative to a clutch outer member (130), the drive plate (110) being also provided with a spring support body (115) for supporting a torsion spring (116), the spring support body (115) being provided raised from a base (111) adjacent to a far end (121a) which is one of the opposite circumferential ends of a drive weight (120) facing the circular cylindrical surface (131) of the clutch outer member (130), the opposite ends (116b, 116c) of the torsion spring (116) being engaged, respectively, with the far end (121a) of one of two clutch weights (120) and with the near end (121b) of the other clutch weight (120).

Description

technical field [0001] The present invention relates to a centrifugal clutch that blocks the transmission of 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, a centrifugal clutch that transmits a rotational drive force to a driven side when an engine reaches a predetermined number of revolutions is used in motorcycles, lawnmowers, and the like. For example, the following Patent Document 1 discloses a centrifugal clutch having a structure in which three clutch weights extending in the circumferential direction of an annular second drive plate are connected to each other by connecting springs in plan view. It is elastically connected and swings relative to the cylindrical surface inside the clutch housing arranged outside the second drive plate. Thus, ...
