Benefits of technology

[0004] An object of the present invention is to devise a drive train of the type mentioned at the outset in a way that will improve its operation and simplify its design, and ensure a cost-effective manufacturing. In addition or alternatively, the operation of the drive train according to the present invention should be especially simple, thereby enabling the use of an economically priced actuating system. It is also additionally or alternatively intended, by the special form and mode of operation of a clutch assembly designed in accordance with the present invention, to improve or optimize its installation between the engine and transmission, and / or to isolate the axial vibrations and wobble originating in the engine.

Problems solved by technology

However, such clutch assemblies have a very complex and expensive design, which also necessitates a very complex actuating system.
In addition, the axial vibrations and wobble produced by the crankshaft are transmitted to the transmission and to the actuating mechanism, so that manifestations of wear and loss of comfort occur.

Embodiment Construction

[0026]FIG. 1 schematically depicts a motor vehicle 1 having a drive train, including a driving engine 2 designed as a combustion engine, a clutch assembly 3, and a transmission 4. Wheels 7 of vehicle 1 are driven via a drive shaft 5 and a differential gear 6. It may, of course, correspondingly concern a vehicle having one or more different driven axles.

[0027] A gear-ratio selector 8, such as selector lever having sensor 9, and a control device 10, 11 are illustrated in a block diagram. Control device 10, 11 may be designed as a unit or in structurally and / or functionally separate sections. If control device 10, 11 is designed in structurally and / or functionally separate sections, these may be interconnected, for example, via a CAN-bus 12 or another electrical connection for exchanging data. Control device 10, 11 controls, for example, the automated actuation of transmission 4 and / or clutches 13, 14 belonging to clutch assembly 3, or engine 2, for example the engine torque, the gear...

Abstract

A drive train having a clutch assembly for transmitting torque between an engine and a transmission. The clutch assembly is selectable for transmitting torque between the engine and the transmission and includes at least one friction clutch, the clutch assembly being supported on the transmission housing so that the clutch assembly is radially fixed and displaceable in an axially limited manner.

Description

[0001] This claims priority to German Patent Application Nos. 103 22 618.4 and 102 26 599, both of which are hereby incorporated by reference herein. [0002] The present invention is directed to a drive train having a clutch assembly for transmitting torque between an engine and a transmission. The present invention is directed, in particular, to such clutch assemblies which include at least one friction clutch for connecting and disconnecting the engine and the transmission to and from one another in terms of drive operation. BACKGROUND [0003] Clutch assemblies having two friction clutches are known, for example, from the German Application DE 28 30 659 A1, hereby incorporated by reference herein. However, such clutch assemblies have a very complex and expensive design, which also necessitates a very complex actuating system. Typically, these types of clutch assemblies are built to be very long axially, so that the dimensional design of the crankshafts, which accommodate these assem...
