Benefits of technology

The solution simplifies the design and actuation of double clutch assemblies, reducing the effort required for engagements and disengagements while maintaining consistent torque transmission characteristics despite wear, thereby improving the overall efficiency and reliability of the system.

Problems solved by technology

This leads to a relatively complicated design, however, because the two engaging / disengaging mechanisms, such as engaging / disengaging piston-cylinder assemblies, must be installed in a small space and thus staggered radially with respect to each other.

Embodiment Construction

[0029] In FIG. 1, a double clutch assembly 10 includes a flywheel 12, which can be or is connected to a drive shaft (not shown) such as a crankshaft, for rotation in common with the shaft. In its radially outer area, an intermediate disk element 14 is rigidly connected to the flywheel 12; the cylindrical section 16 of this disk element is bolted by a plurality of threaded bolts 18 or the like to the flywheel 12. The intermediate disk element 14 works together equally with the two different clutch areas 20, 22 of the double clutch assembly 10.

[0030] The first clutch area 20 comprises a first pressure plate 21, the first friction surface 24 of which can be pressed against friction linings 26 of a clutch disk 28 of the first clutch area 20. When this happens, the friction linings 26 of the clutch disk 28 are pressed against a second friction surface 30 of the first clutch area 20, located on the intermediate disk element 14.

[0031] The double clutch assembly 10 also includes a second pr...

Abstract

A first clutch area produces a first torque-transmitting connection between a drive element and a first driven element, and a second clutch area produces a second torque-transmitting connection between the drive element and a second driven element. A common engaging / disengaging mechanism actuates the first clutch area and the second clutch area to produce and to nullify the first and second torque-transmitting connections.

Description

[0001] 1. Field of the Invention[0002] The present invention pertains to a double clutch assembly, comprising a first clutch area for the optional production of a first torque-transmitting connection between a drive element and a first driven element, and a second clutch area for the optional production of a second torque-transmitting connection between the drive element and a second driven element.[0003] 2. Description of the Related Art[0004] Double clutch assemblies of this type are used, for example, in conjunction with variable gear transmissions which have two transmission input shafts. Different gear stages can be engaged, depending on which of the transmission input shafts is in the torque-transmitting path after actuation of the associated clutch area. To implement the engagements and disengagements of the clutch, it is known in double clutch assemblies of this type that each clutch area can have its own, separate engaging / disengaging mechanism, so that, depending on the ac...
