Problems solved by technology

Another disadvantage is that the mechanism must be mounted on the middle plate with the hole or notch in the middle plate and a separate fastener, so the known clutch assembly is complicated in structure and increases in manufacturing cost.
There is also a disadvantage that to protect the drive belt from damage against direct abutment of the spacer and to more precisely control the movement of the compression plate relative to the middle plate, the spacer must directly abut / engage the bar
Another disadvantage is that the maximum axial movement of the intermediate plate is generally not controlled, so that the attached drive belt can be overstretched and break

Embodiment Construction

[0021] The accompanying drawings show in detail various preferred embodiments of the invention. figure 1 is a schematic diagram of a double disc friction clutch 20, and figure 2 is a partial sectional view of the clutch 20 . Clutch 20 includes a cover 22 removably mounted on a flywheel 24 of an internal combustion engine (not shown). Cover 22 houses a first friction disc 26 adjacent to flywheel 24 and an intermediate plate 28 adjacent to first friction disc 26 . A second friction disc 30 is adjacent to the transmission-facing side 32 of the intermediate plate 28 and a pressure plate 34 is adjacent to the transmission-facing side 36 of the second friction disc 30 . The first and second friction plates 26, 30 are fixed for rotation on a transmission input shaft 38, but are axially movable relative to each other.

[0022] The middle plate 28 and the pressure plate 34 are fixed to be rotatable together with the cover 22 and relatively movable in the axial direction like the fr...

Abstract

A friction clutch (20) is provided that includes a clutch cover (22), an intermediate plate (28) that is spaced apart from an engine flywheel (24), a first friction disk (26) positioned between the flywheel (24) and the intermediate plate (28), a pressure plate (34) spaced apart from the intermediate plate (28) and a second friction disk (30) positioned between the intermediate plate (28) and the pressure plate (34). The clutch (20) further includes a first drive strap (44) for applying a load to the intermediate plate (28), a second drive strap (46) for appliying a load to the pressure plate (34) and a separator arm (79) attached to the intermediate plate (28). The separator arm (79) engages the second drive strap (46) such that axial movement of the intermediate plate (28) relative to the clutch cover (22) is a fraction of the corresponding axial movement of the pressure plate (34) during engagement and disengagement of the clutch.

Description

technical field [0001] The present invention generally relates to a multi-disk friction clutch, in particular to a multi-disk friction clutch capable of improving the engagement and wear uniformity of the friction discs. Background technique [0002] Friction clutches for transferring torque between a motor vehicle engine and a transmission are well known. A known friction clutch includes two friction plates mounted for rotation about a common axis, a pressure plate / plate, an intermediate plate / plate and a clutch cover. The two friction discs, the pressure plate and the middle plate can move axially relative to each other, so that the pressure plate can move relative to the cover to make the two friction discs and the interposed middle plate axially press against an engine flywheel. A series of drive straps, each comprising one or more elastic members laminated into a leaf spring, are distributed over the periphery of the intermediate and pressure plates to exert a biasing ...
