Definitions
- the invention relates to release bearings, such as those used for operating switch disconnect clutches of internal combustion engines.
- release bearings which are arranged on a so-called sliding sleeve.
- release bearings are generally formed by an inner ring and an outer ring, wherein the outer ring surrounds the inner ring coaxially.
- rolling elements are provided which roll between the raceways provided by the inner and outer rings.
- the outer ring of such a release bearing is in physical contact with the diaphragm springs of a shift disconnect clutch, while the inner ring is in operative connection with a housing or is connected to this rotationally and non-displaceably.
- DE 102013208715 Such an arrangement is known from DE 102013208715.
- the outer ring is displaced axially by the intermediary of the housing, the inner race and the rolling bodies against the action of the diaphragm springs.
- the axial force of the housing triggering force is generally introduced via a known from DE 102012219496 release lever, the central region rests against the housing or is penetrated by this.
- One end of the release lever is pivotally mounted.
- the other end of the release lever is in operative connection with the clutch pedal. If this is actuated, performs the release lever through the intermediary of a mechanical or hydraulic connection between the clutch pedal and release lever pivotal movement, which is then converted by the physical contact of the release lever to the housing in an axial movement of the housing.
- the composite of levers and web can be connected as a unit to the shaft be without having to take special measures to align the lever on the shaft when connecting. If each lever on the side facing the other lever has a flat projection running axially and radially with respect to the axis of rotation of the shaft, and if the two projections are in contact with rounded bearing bearing surfaces provided by the housing, the seal between the Lever and housing excluding Abroll movement created ung, since the flat or straight lugs roll on or on rounded abutment surfaces, without causing a sliding movement.
- levers and the web connecting the levers are formed in one piece, for example as a stamped or cast part, since such one-piece formations can be produced with high process reliability and at low cost.
- connection of the shaft and lever when the shaft passes through a hole in the levers and the levers on the shaft are fixed by means of pins which are guided by the shaft and the levers and / or webs.
- the pins each provided with a slot extending in the direction of its longitudinal extent, a connection is created, which does not require high, the shaft deforming pressing forces, in contrast to conventional press-fit, because through the slots in the pins, the pins, which have a slight oversize relative to the receiving bores into which they are inserted, are slightly elastically deformed during insertion and are i.ü. at the same time develop a self-holding effect when they have taken their final position in the mounting holes.
- a comfortable response of the clutch is given when the pins are elastically deformable under the action of the torque of the shaft. This desired elasticity can already be realized in that Slots in the pins have a certain yielding.
- the invention also includes pins whose material has a lower modulus of elasticity than the material of the shaft and / or the lever.
- a release bearing a release bearing of Figure 1 in section above the Rotati onsachse.
- a variant of a disengagement arrangement according to the invention a further variant of a disengagement arrangement according to the inven tion.
- Fig. 1 shows a release bearing 1 as used to actuate a shift disconnect clutch of motor vehicles.
- FIG. 1 two contact surfaces 5.1, 5.2 are provided on the housing 3. hen, which are rounded and formed with two Ausschhebeln 6 (which are only indicated in Fig. 1, which will be discussed later separately) in operative connection. If a force K is now exerted on the abutment surfaces 5.1, 5.2 by the disengagement lever 6, the housing 3 and with it the outer ring 2 are moved to the right with the direction of the figure.
- the release bearing 1 according to FIG. 1 is shown in more detail. This illustration can be taken that the outer ring 2 surrounds an inner ring 10 coaxially. Between inner ring 10 and outer ring 2, 10 roll on from inner and outer ring 2, 10 additionallygesellte raceways 1 1 rolling elements 12 from.
- a variant of a disengaging assembly 13 is shown.
- This disengaging assembly 13 includes a rotatable shaft 14 and two axially spaced release lever 6 and the release lever 6 connecting web 15.
- the web 15 and the lever 6 are made as a stamped part in one piece.
- the two levers 6 are provided on their sides facing each other with flat, axially and radially to the shaft 14 extending lugs 7. These flat lugs 7 are in physical contact with rounded abutment surfaces 5.1, 5.2 according to FIG. 1, which however are concealed in FIG. 3 by lugs 7.
- FIG. 4 A further variant of a disengagement arrangement 13 is shown in FIG. 4. There, too, the combination of levers 6 and web 15 is integrally formed. In contrast to the embodiment of FIG. 3 is in the embodiment according to Fig. 3 no hole present, but a rolling edge 18 is provided which describes a three-quarter circle and in the connected state with the shaft 14 (not shown in Fig. 4) is completely penetrated by this. Above the disengagement 13 are shown two variants of pins 17.1 and 17.2, with which the unit of levers 6 and web 15 is pinned to the shaft 14.
- pin 17.1 has a smooth-walled shaft 19 and a head 20
- the pin 17.2 is formed free of head. Is used to connect the unit of levers 6 and web 15 of the rolling edge 18 of the shaft 14 and the pins 17.1 and 17.2 are pressed into the pin holes 21 of shaft 14 and the unit of levers 6 and web 15, a rotationally fixed connection is made ,
- shanks 19 of the pins 17. 1, 17. 2 have a slight oversize relative to the pin bores 21, which causes self-mounting of the pins 17. 1, 17. 2 in the pin bores 21.
- a slot 22 which extends in the longitudinal direction of the pin 17.2. Because of the slit 22 caused by the flexibility of the pin 17.2 ensures that even very small press-in forces sufficient to produce a pinning, without having to worry that loosened thanks to the restoring forces of the pin 17.2 again.
- the pins 17, 17.1, 17.2 are made of a material whose modulus of elasticity is less than the modulus of elasticity of the material from which the shaft 14 or the unit of levers 6 and web 15 is made. Since the shaft 14 made of steel or the unit of levers 6 and web 14 are made of sheet steel, pins 17, 17.1, 17.2 made of copper or brass as sufficiently yielding pencil materials.
