Embodiment Construction

[0043] figure 1 The transmission unit 1 rotating about the motor axis 32 is shown in a sectional view. The end of the output shaft 2 with a flywheel 16 is shown on the left side of the figure. The input shaft 7 is rigidly connected to the flywheel 16 or the driven shaft 2 via a rigid connection 13 . Here, the rigid connection 13 is fixed on the outer circumference 17 of the flywheel 16 . as for example in figure 2 As shown in the top view in , the rigid connection part 13 has a radially arranged spring set 14 . Connected to the input shaft 7 is a transmission disc 18 which forms the input-side connection part 20 of the arc-shaped damping spring 22 of the damping system 12 . The clutch hub 19 then forms the output-side connection part 21 of the arc-shaped damping spring 22 , thus forming a damper in the wet chamber 35 of the friction clutch 6 . The drive plate 18 and the clutch hub 19 together form a co-rotating clutch housing 11 . A plurality of pressure plates 23 and a...

Abstract

The invention relates to a transmission unit for transmitting torque from a driven shaft of a drive unit to a driving shaft of a drive train, comprising a wet friction clutch having at least the following components: at least one input shaft on the input side ; at least one output shaft on the output side; at least one friction system for releasably connecting the at least one input shaft with the at least one output shaft for torque transmission; and at least one co-rotating clutch housing body for positioning the friction system, the transmission unit is characterized in that at least one damping system is provided in the co-rotating clutch housing to connect the input shaft with at least one output shaft in a vibration-decoupled manner, and, The input shaft can be rigidly connected with the driven shaft of the drive unit by a rigid connector. Such an integrated design of the transfer unit enables use with a small installation space and a low moment of inertia, so that a high efficiency can be achieved.

Description

technical field [0001] The invention relates to a transmission unit for transmitting torque from an output shaft of a drive unit to a drive shaft of a drive train, comprising a wet friction clutch with an integrated damping system. The friction clutch is in particular a wet double clutch. Wet clutches or wet double clutches are clutches or double clutches that are filled with a cooling fluid that serves to dissipate the generated heat. The transmission unit is preferably used to transmit torque from the crankshaft of the internal combustion engine to a transmission shaft of a shift transmission, for example of a motor vehicle. In this case, a damping system is used to loosen the vibrations of the drive unit and the drive train or transmission. Background technique [0002] Combustion engines in particular generate vibrations and torque peaks that can overload connected components and generate annoying noise. It is therefore desirable to eliminate vibrations and torque pea...
