Problems solved by technology

When the engaging surfaces become fouled with debris from the clutch, it makes it more difficult to properly adjust the clutch to compensate for any wear of the friction components

Embodiment Construction

[0031] FIG. 1 shows a friction clutch 10 for a motor vehicle. Clutch 10 rotates about axis 12 . A flywheel 14 is rotatably secured to the engine crankshaft (not shown) of the motor vehicle. A driving disc 16 , concentric with axis 12 , has a hub engaged with input shaft 17 . The friction member 18 of the driving disc 16 engages with the engaging surface 20 of the pressure plate 22 on one side and engages with the engaging surface 24 of the flywheel 14 on the other side.

[0032] A cast iron cover 26 is placed over the platen 22 and secured to the flywheel 14 . Several straps 28 are provided between the pressure plate 22 and the cover 26 in the circumferential direction. Straps 28 rotatably secure the pressure plate 22 to the cover 26 while allowing axial movement of the pressure plate relative to the cover 26 . Six levers 30 extend radially outwardly from a release release assembly 34 onto the adjustment mechanism 32 . The levers 30 engage the pressure plate 22 at a point...

Abstract

A frictional clutch for a motor vehicle includes a cover, a pressure plate, a biasing member, an adjustment mechanism and an annular shield. The cover has an axis of rotation. The pressure plate is coupled to the cover for rotation therewith about the axis. The pressure plate has a frictional engagement surface substantially normal to the axis. The biasing member is interposed between the cover the pressure plate, and biases the pressure plate toward an engaged pressure plate position. The adjustment mechanism is centered about the axis and is located at a first radial distance from the axis. The adjustment mechanism is operably disposed between the biasing member and one of the pressure plate and the cover. The annular shield is disposed radially within the adjustment mechanism. The annular shield is axially alignment with the adjustment mechanism. The shield is sized and oriented to protect the adjustment mechanism from debris radiating outward from a central area of the clutch.

Description

technical field [0001] The invention relates to the field of friction clutches, in particular to a friction clutch with an adjustment mechanism. Background technique [0002] Known friction clutches provide a releasable torsional connection between a motor vehicle engine flywheel and an associated transmission. Repeated disengagement and engagement of the clutch wears down the friction material of the clutch drive disc. Wear results in a change in the axial position of the pressure plate at the joint. A change in axial position results in a reduction in clutch engagement force or clamping load. Clutches are usually provided with an adjustment mechanism to compensate for this wear. [0003] The desired clamping load of the clutch is achieved by applying a spring load to the pressure plate. One type of clutch applies a spring load to several radial levers that sequentially engage pressure plates. If a compression or canted spring is used, the spring load is usually applie...
