Clutch device

Abstract

The invention relates to a clutch device, comprising at least one plate pack which can be compressed axially by means of an actuating element and has an outer plate and an inner plate each of which can be moved axially in an axially extending toothing of a plate carrier. According to the invention, the outer plate engages with teeth formed on the outer circumference into an axially extending tooth channel of a tooth formed on the inner circumference of a plate carrier, and the inner plate engages with the teeth formed on the inner circumference into an axially extending tooth channel of a tooth formed on the outer circumference of the plate carrier. According to the invention, window-like perforations are introduced on the blade carrier in the region of a plurality of tooth roots of the blade-carrier-side toothing, such that a web is formed on each perforation. The web is bent radially into the respective toothing channel in order to form the carrier section, the outer piece or the inner piece is supported by teeth on the bearing section, or a bearing support ring with outer teeth or inner teeth is supported by the teeth on the bearing section.

Description

technical field [0001] The invention relates to a clutch device comprising at least one plate pack which can be compressed axially by means of an actuating element, said plate pack having an outer plate and an inner plate which can respectively be mounted on a plate carrier Axial movement in the axially extending toothing, wherein the outer plate fits into the axially extending toothing channel of the toothing formed on the inner circumference of the plate holder with teeth configured on the outer periphery, and the inner plate The teeth on the inner circumference fit into axially extending toothing channels of the teeth formed on the outer circumference of the disc carrier. Background technique [0002] Such a clutch device is used in a known manner to temporarily establish a torque-transmitting non-positive connection between the drive shaft of the internal combustion engine or the electric motor and the output shaft extending to the transmission. When the clutch device i...

Problems solved by technology

However, if the plate carrier is a common plate carrier with active toothing on both sides, for example in a clutch arrangement of a hybrid drive train, these embossments in the respective tooth roots caused by embossing cause problems because they reduce the the depth of the associated tooth channel, which results in the length of the teeth that fit into the tooth channel having to be slightly shortened, because otherwise the pieces cannot be inserted into the tooth

On the one hand, this results in a specific plate geometry to be produced, on the other hand, due to the shortened teeth, the pressure prevailing between the tooth flanks of the plate carrier and the teeth of the plate pack is constantly increasing, and therefore the existing toothing length does not fully exploited
