Embodiment Construction

[0030] The following will refer to Figure 1 to Figure 9 An embodiment of the friction clutch according to the invention will be described in detail.

[0031] figure 1 The friction clutch 1 shown in may be provided, for example, on a power transmission path between an engine and a transmission of a motorcycle (not shown). exist figure 1 The input member 2 at the outermost position in 2 receives power from a power source (not shown) and rotates. Although for ease of understanding of the structure, figure 1 The input member 2 shown in is shown as one part, but it includes an input gear 3 that meshes with a drive gear (not shown) on the power source side and is connected to the input gear 3 via a torque damper (not shown) The cylindrical clutch housing 4.

[0032] The input member 2 is rotatably supported by a bearing 6 through an output shaft 5 located at an axial portion. The output shaft 5 receives power from the friction clutch 1 and rotates. When the friction clutch 1...

Abstract

A friction clutch (1) equipped with an input member (2), a friction clutch mechanism (7), a first rotating body (21), a back torque limiter mechanism (25), and a second rotating body (23). The friction clutch mechanism (7) has multiple friction plates (8, 11) and a pressure plate (12) that presses these friction plates (8, 11). The back torque limiter mechanism (25) has a cam groove (44) on the first rotating body (21) side, a cam groove (45) on the second rotating body (23) side, and a ball (41) between these cam grooves (44, 45). The cam grooves (44, 45) have a hemispherical mating section (47, 51) and an inclined cam section (48, 52). Due to the movement of the ball (41) from the mating section (47, 51) to the inclined cam section (48, 52) an end portion (61) of the first rotating body(21) pushes the pressure plate (12) in the opposite direction from the friction plates (8, 11).

Description

technical field [0001] The present invention relates to a friction clutch having a reverse torque limiter mechanism that prevents transmission of excessive torque (reverse torque) from an output side to an input side. Background technique [0002] In motorcycle driving, it is sometimes necessary to downshift to slow down. The rotational speed of the clutch shaft is increased by the difference between the gear ratio of the gearbox before the shift and the gear ratio after the shift. If the clutch is connected at this time, the engine speed increases as the rotation speed of the clutch shaft increases. The torque at the clutch shaft that increases the engine speed is called counter torque. [0003] The engine brake tends to be strong at high engine speeds. If the clutch is inadvertently connected after the downshift operation, engine braking is applied, a phenomenon known as slipping or bouncing occurs between the driving wheels and the road surface, and the position of the...
