Embodiment Construction

[0047] Hereinafter, embodiments for implementing the present invention will be described with reference to the drawings. This example is a brush cutter that combines the connection and separation mechanism of the throttle metal wire and the connection and separation mechanism of the wire in the connection and separation structure of the present invention that connects and disconnects the clutch shoe 11 and the clutch drum 21 for the centrifugal clutch. The operating lever 4 extended from the adapter 2 is equivalent to the main engine described in the present invention. The join-detach construct for this example is as follows Figure 1 to Figure 4 As shown, it is composed of the engine side adapter 1 at the front of the engine 3 and the host side adapter 2 at the rear end of the above-mentioned operating rod 4 . In the control lever 4 of the brush cutter, an output shaft 32 on the main machine side as a power transmission shaft is built in (refer to image 3 ), through which ...

Abstract

A structure for connection and separation between an engine and a main unit, adapted to release coupling by separating a centrifugal clutch. A structure for connection and separation between an engine and a main unit, comprising: an engine-side adapter (1) provided with a clutch shoe (11), an engine-side annular surface (121), and engine-side projections (13); and a main unit-side adapter (2) provided with a clutch drum (21), a main unit-side annular surface (221), and main unit-side projections (23). The engine-side projections (13) project in the radial direction from a circle centered on the axis of a power transmission shaft, and the main unit-side projections (23) project in the direction radially opposite to the direction in which the engine-side projections (13) project. When either the engine-side adapter (1) or the main unit-side adapter (2) is rotated relative to the other about the axis of the power transmission shaft with the engine-side annular surface (121) and the main unit-side annular surface (221) made to be in contact with each other, the engine-side projections (13) and the main unit-side projections (23) are moved relative to each other in the circumferential direction to the rear surface side of the corresponding mating projections (13, 23) and engaged with each other in the axial direction of the power transmission shaft.

Description

technical field [0001] The present invention relates to a connection-disconnection structure of an engine and a main engine by separating a clutch shoe and a clutch drum of a centrifugal clutch provided on a power transmission shaft to release the connection. Background technique [0002] In the brush cutter, a rotating blade is attached to the front end of the power transmission shaft built in the operating rod (main unit), and the rear end of the power transmission shaft is connected to the engine to transmit the rotational power of the engine to the rotating blade. In this brush cutter, a throttle lever is provided on a handle of an operating rod, and a metal wire extending from the throttle lever is connected to a throttle valve of an engine. The power transmission shaft is configured by connecting an output shaft on the main machine side to a rotating shaft on the engine side via a centrifugal clutch. If the output of the engine is above a certain level, the output sha...
