- FIG. 1 is a perspective exploded view of parts of a friction clutch according to the invention
- Fig. 3 is a partial perspective view of a pressure plate attached thereto Eisengeberbauocc and
- FIG. 4 shows a cross section through a game encoder assembly.
- a friction clutch 1 and 2
- a housing 10 an annular disc-shaped, plate spring-like spring lever 12, an adjusting ring 14 and a pressure plate 16.
- the spring lever 12 is secured by means of rivets 18 on the housing 10, wherein between the spring lever 12 and the housing 10 as a first bearing a wire ring 20 is disposed and between the heads of the rivets 18 and the spring lever 12 as another Bearings another wire ring 22 is arranged. In its radially outer region, the spring lever 12 is supported via the adjusting ring 14 on the pressure plate 16. Structure and function of the previously described friction clutch are known per se.
- the housing 10 can be screwed to a counterpart component, for example the flywheel 24 of an internal combustion engine.
- the spring lever 12 represents a force storage, which causes a frictional contact pressure of the clutch disc to the pressure plate and the flywheel in its idle state.
- the game generator assembly 26 comprises a support body 30 formed overall in the form of a stepped cylinder. which has a projection 34 formed with a recess 32, which is rigidly connected to the leaf spring 28 (FIG. 3).
- the support body 30 has a through hole 40 provided with an internal thread 38, through which extends an internal spindle 42 serving as a feeler component, which has an external thread 44 which is in non-self-locking engagement with the internal thread 38.
- the support body 30 further comprises an external thread 46, which is in threaded engagement with an internal thread 48 of a cup-shaped sleeve or outer spindle 50, the bottom 52 of the support body 30 engages over and is formed with a lug 54 through which the inner spindle 42 extends.
- the inner spindle 42 and the outer spindle 50 are rotatably connected to each other via a connecting device 56 in substantially each relative rotational position.
- the Spielgeberbauen 26 forms a directional freewheel. Due to the different diameters of the threaded engagement between the inner spindle 42 and the support body 30 is not self-locking, whereas the external threaded engagement between the support body 30 and the outer spindle 50 is self-locking.
- the friction range in which the two spindles can work is, for example, between 0.05> ⁇ > 0.3, ie at a factor of 6.
- the operating point of the directional freewheel is adjustable because the non-rotatable coupling between the inner spindle 42 and the outer spindle 50 is detachable and lockable in any relative rotational position.
- the operation of the game encoder assembly 26 is as follows:
- the adjusting ring 14 is formed with ramp surfaces 60 which cooperate with formed on the pressure plate 16 ramp surfaces such that a rotation of the adjusting ring 14 of FIG. 1 in the clockwise direction (arrow B) to an increase in the distance between the top of the adjusting ring 14 and the pressure plate 16 leads.
- the adjusting ring 14 is provided with radially projecting planar lugs 62, which engage in a circumferential groove 64 (FIG. 4) which is formed in the overall cylindrical outer wall of the outer spindle 50.
- the axial width of the circumferential groove 64 is greater than the axial thickness of the neck 62.
- the adjusting ring 14 is biased by one or more springs, not shown, in the adjustment direction (arrow B direction).
- the springs may be formed, for example, as arranged in the circumferential direction coil springs which engage the Nachsteflring and the pressure plate.
- the entire game encoder assembly 26 is first moved against the force of the leaf spring 28 of FIG. 4 up or toward the housing 10 so that the side wall 66 of the circumferential groove 64 is released from the neck 62 and the outer spindle 50 is released for rotation.
- This relative displacement causes the outer spindle 50 to move relative to the pressure plate 16 in the direction of the housing 10, that is, the engaging in the circumferential groove 64 approach 62 of the adjusting ring 14 of the side wall 66 of the circumferential groove 64 substantially the same Distance removed, as the inner spindle 62 rotates into the support body 30.
- the housing above the toy generator assembly 26 is advantageously provided with a through opening 68, through which the upper side of the outer spindle 50 and the upper end side of the inner spindle 42 or the connecting device 56 are accessible.
- the inner spindle 42 are adjusted by turning relative to the rotatably held on the pressure plate 16 supporting body 30 so that not worn clutch disc, the inner spindle 42 does not come into engagement with the flywheel 24 when the clutch is engaged.
- the outer spindle 50 can be adjusted so that the top of the lug 62 just touches the side wall 66 of the circumferential groove 64. In this way, the game encoder assembly 26 can be adapted to the respective clutch.
- the inner spindle 42 and the outer spindle 50 are rotatably connected to each other by means of the connecting device 56.
- the connection device There are various possibilities for the design of the connection device.
- One possibility is, for example, that the projection 54 of the outer spindle 50 is provided with a toothing and the end portion of the inner spindle 42 is provided with a toothing, wherein the pitches of the two gears are different and a connecting part is provided, which engages in both teeth. In this way, a rotationally fixed connection between the two spindles can be produced, the accuracy of which depends on the difference in the numbers of teeth of the circumferential teeth.
- This 6 ° means a setting accuracy of 0.1 mm based on the operating point of the spring lever 12.
- the inner spindle 42 may be formed only within the support body and abut with its lower side according to FIG. 4 on a bolt which is inserted into the support body (for example, in Fig. 2 indicated).
- the domestic market could Spindle be axially fixed with one end relative to the housing and move the outer spindle with the pressure plate.
