Abstract

The invention relates to a disc clutch intended for mounting in the flywheel cavity of an internal combustion engine for which it is designed reinforcement of cover and pressure plate behind while improving its internal cooling space. The essence of the adjustment is to create of the radial recesses in the clutch cover in conjunction with the flywheel air ducts draw off the air rotation of the coupling and radial reinforcement with ribs provided with a pressure coil touče. Disc Clutch by Subject You finding finds application especially in incineration motor vehicles, aggregates etc.

Description

The invention relates to a disc clutch with a diaphragm spring mounted between thrust rings, connected by spacers to the clutch cover and centered circumferentially in the projections of the thrust disk.

Well-known disc clutches with a diaphragm pressure spring are known for their advantageous properties and are designed for various flywheel shapes of internal combustion engines. Couplings mounted on a flat Flywheel face are closed for a molded lid whose functional openings located on its periphery have in most cases sufficient cross-section to evacuate the centrifugal effect of the intake air, which effectively cools both the pressure plate and the plate.

This advantage is devoid of flywheel recessed couplings, the lid of which is formed by a flat plate, which closes the flywheel inner space along the circumference of its cavity, limiting the possibility of efficient ventilation and cooling. The consequence of this is an increase in operating temperatures, higher demands on the quality of the friction lining of the lamella and, last but not least, a reduction in the service life of the coupling.

These disadvantages are overcome by the disc clutch according to the invention in that the clutch cover has radial recesses at the points of attachment of the support rings, terminated by cut-outs on the circumference and on the adjacent face of the pressure plate radial ribs.

Radial indentations in the clutch cover increase its stiffness in the axial direction and create vents widened at their mouths by slits through which air from the flywheel cavity is drawn off by the rotating clutch and radial ribs of the pressure plate.

An exemplary embodiment of a disc clutch according to the present invention is shown in the annex, wherein Fig. 1 is a view of the assembled clutch and Fig. 2 is a sectional view taken along line α-δ in Fig. 1.
