Abstract

A two-stage clutch for separable connection of an input shaft to at least one output shaft, having a clutch cover, a clutch basket and a plurality of partial clutches, the partial clutches being operated in series. A first partial clutch is a pilot clutch, which is actively operable. A second partial clutch is a main clutch, which is operable by the pilot clutch, an operating force for the main clutch being produced by a torque transmitted by a shaft. In this two-stage clutch, the clutch cover is firmly connectible to the clutch basket. With the two-stage clutch proposed here, high torques can be transmitted despite small external operating forces. At the same time, the construction and assembly are greatly simplified in spite of the considerable complexity of the two-stage clutch, and the two-stage clutch has a significantly reduced rotating mass.

First claim

What is claimed is:

1 - 10 . (canceled)

11 : A two-stage clutch for separable connection of an input shaft to at least one output shaft, comprising:
a clutch cover; a clutch basket; and, a plurality of partial clutches where the plurality of partial clutches are operated in series, and where a first partial clutch is a pilot clutch which is actively operable and a second partial clutch is a main clutch which is operable by the pilot clutch and an operating force for the main clutch being produced by a torque transmitted by a shaft, wherein: the clutch cover is firmly connectible to the clutch basket.

12 : The two-stage clutch according to claim 11 , wherein a modulating spring to modulate a transmission of power when operating one of the first or second partial clutches is located between the clutch basket and a plate carrier of the main clutch.

13 : The two-stage clutch according to claim 11 , wherein the two-stage clutch is a wet friction clutch.

14 : The two-stage clutch according to claim 13 , wherein a liquid coolant can be brought into the main clutch from a hollow shaft through at least one window in a transmitting element between the pilot clutch and the main clutch.

15 : The two-stage clutch according to claim 11 , wherein the clutch basket is fabricated by cold rolling.

16 : The two-stage clutch according to claim 15 , wherein the clutch basket is fabricated with a reduced mass.

17 : The two-stage clutch according to claim 11 , wherein the pilot clutch can be operated by pulling by means of a diaphragm spring.

18 : The two-stage clutch according to claim 17 , wherein the pilot clutch forms a separate component.

19 : The two-stage clutch according to claim 15 , wherein the clutch cover is connectible and fixable on the clutch basket by means of a bayonet lock.

20 : The two-stage clutch according to claim 19 , further comprising a plurality of openings in a disk of the pilot clutch which correspond to at least one pin on the main clutch.

21 : The two-stage clutch according to claim 17 , wherein a transmitting element can be centered between a first ramp element and the main clutch by means of the diaphragm spring.

22 : The two-stage clutch according to claim 17 , wherein a clamping force that is produced is absorbed in the clutch basket.

23 : The two-stage clutch according to claim 22 , wherein a torque sensor is not detachable from a ramp system without destruction.

24 : A motorcycle having a drive unit with an output shaft, a drivetrain and a two-stage clutch according to claim 11 to connect the output shaft to the drivetrain separably.

25 : The motorcycle according to claim 24 , wherein the two stage clutch is operable by hand.
