4:

• The clutch device (100) according to claim 3 wherein the second ring element (59) comprises, on a front face (64) associated with the first ring element (58), recesses (65) for receiving end faces (66) of sleeves (46).

5:

• The clutch device (100) according to claim 1 wherein the pin body (31) is arranged so that the longitudinal central axis (32) of the pin body (31) forms an internal angle (α) of less than 90 degrees with the longitudinal central axis (33) of the second clutch member (23).

6:

• The clutch device (100) according to claim 1 wherein the receiving bore (29) has a passage (37) in a radially outer region of the receiving bore, which passage provides for the passage of lubricant, and movement of the pin body (31) and the compression spring (30) acting on the pin body (31) through the passage (37) is prevented by the radially outer region.

7:

• The clutch device (100) according to claim 1 wherein a plurality of pin bodies (31) are arranged on a hub (38) of the third clutch member (17) starting from the inner recess (34), and are releasably engageable with respective engagement recesses (40) arranged on a hub (39) of the second clutch member (23).

8:

• The clutch device (100) according to claim 7 wherein at least one of the engagement recesses (40) is provided with an entry chamfer (41), on an outer surface of the hub (39), formed at an angle to the longitudinal central axis (33) of the second clutch member (23), and merging into a stop surface (43) of the at least one engagement recess (40).

9:

• The clutch device (100) according to claim 1 wherein the third clutch member (17) has shaped surfaces (67) arranged at an angle to a cross-sectional plane extending at right angles to the longitudinal central axis (36), which shaped surfaces (67) engage with other shaped surfaces (68) provided at another angle to the second clutch member (23) so that, during traction operation of the clutch device (100), a force acts on the third clutch member (17) in a direction of the second clutch member (23).

10:

• The clutch device (100) according to claim 1 wherein the third clutch member (17) has a cylinder-segment-shaped hub body (44) on an outer circumference of which are defined a plurality of longitudinal grooves (45), each of the grooves is circular-segment-shaped in a cross-sectional view of the hub body (44), and wherein the grooves receive hollow cylindrical sleeves (46) on the outer surfaces (47) of which the second clutch plates (5) are axially displaceably arranged.

11:

• The clutch device (100) according to claim 10 wherein the sleeves (46) are each provided, at an end region associated with the pressure-receiving plate (28), with a groove-shaped recess extending in a circumferential direction, into which engages a corresponding radially outer plate-segment-shaped region (54) of the setting device (20) for axially fixing the sleeves (46) engage.

12:

• The clutch device (100) according to claim 1 wherein the second clutch member (23) has a tubular portion (48) extending in a direction of the clutch pressure plate (4), on an outer circumference of which a tubular bearing sleeve (49) of a predetermined working length is disposed, the bearing sleeve comprising a radially outwardly extending rotating collar (55) having an abutment surface (69) on which a spring device (14) is arranged, which spring device (14) axially biases the third clutch member (17) and limits a path of axial displacement of the third clutch member (17) relative to the second clutch member (23).

13:

• The clutch device (100) according to claim 12 wherein the spring device (14) comprises a diaphragm spring, a spring force of which is predeterminable by selecting an axial disc dimension for the diaphragm spring, and the diaphragm spring influences an amount of a transmittable back torque, before partial opening of the clutch device (100), by an axial displacement of the third clutch member (17) relative to the second clutch member (23).

14:

• The clutch device (100) according to claim 13 wherein the predetermined working length of the bearing sleeve (49) is determined between the abutment surface (69) and a contact surface (70) of the bearing sleeve (49), and the predetermined working length is variable by means of different bearing sleeves (49) in such that an amount of the axial displacement of the third clutch member (17), relative to the second clutch member (23), is determined by a sum of the axial disc dimension for the diaphragm spring and the working length of the bearing sleeve (49).

15:

• The clutch device (100) according to claim 1 wherein the receiving bore (29) is disposed relative to the inner recess (34) such that the longitudinal central axis (35) of the receiving bore (29) forms an internal angle of less than 90 degrees with the longitudinal central axis (36) of the inner recess (34).

16:

• The clutch device (100) according to claim 5 wherein the internal angle (α) has a value in the range of 50 degrees to 80 degrees inclusive.

17:

• A motorcycle having a front wheel, a rear wheel, and a drive motor, and comprising a clutch device (100) according to claim 2.
