Problems solved by technology

[0003] In the known state of the art, however, there is a relatively high frictional hysteresis in the region of the pivoting bearing of the disc spring-like component on the housing, so that in such friction clutches the engagement force curve differs from the disengagement force curve. significantly

Embodiment Construction

[0018] The friction clutch 1 shown in these figures has a housing 2 here made of sheet metal and a pressure plate which is non-rotatably connected to the housing but displaceable in a limited axial direction. The disc is not shown here. Axially clamped between the pressure plate and the cover 2 is a compression disc spring 4 which, as can be seen in particular from FIG. The radial height of the support region 5 pivots like a double-armed lever. The disk spring 4 acts on a pressure plate with a radially far outer region 3 . The pressure plate is non-rotatably connected to the housing 2 via leaf springs directed in the circumferential direction or tangentially. The friction clutch 1 can be mounted on a counter-pressure plate, not shown here, wherein a frictional contact between the friction surface of the counter-pressure plate and the friction surface of the pressure plate can be carried out in a known manner, precisely on the basis of tension by a disk spring 4 . The axial ...

Abstract

The present invention relates to a friction clutch which is especially for the motor vehicle, the friction clutch comprises a clamp plate which is connected with a casing with the mode that no relative rotation exists but the movement in the axial direction is restricted, wherein, a disk spring type component is arranged between the casing and the clamp plate, and the disk spring type component is supported in an annular swinging area arranged on the casing on one hand and on the other hand is used for applying load to the clamp plate in the direction of the friction plate lining of the clutch disk.

Description

technical field [0001] The invention relates to a friction clutch, in particular for a motor vehicle, which has a pressure plate which is non-rotatably connected but displaceably axially limited to a housing, In this case, a disc spring-like component is arranged between the housing and the pressure plate, which is supported on the one hand on an annular pivot area arranged on the housing and on the other hand for The pressure plate is loaded in the direction of the friction lining of the clutch disc, and the disk spring-like component is also subjected to a blocking force generated by spring means in the direction of the pivoting region in the axial direction. It is carried by the disc spring-like component and is supported with pretension on the housing. Background technique [0002] Such clutches are known, for example, from US 4,210,233 and DE 34 33 644 C2. [0003] In the known state of the art, however, there is a relatively high frictional hysteresis in the region o...
