Description
The present invention relates to a kind of have claim 1 summation feature, for the separative element of double clutch.
Double clutch consists essentially of two independent clutch units, and these clutch units can disconnect respectively by the segregating unit of attaching troops to a unit and be formed and the connection of transmission input shaft with being independent of each other.The preferred use field of this double clutch is applied together with dual-clutch transmission.First clutch unit is generally used for the gear range of odd number here, and second clutch unit is generally used for the gear range of even number.By this way, to be delivered to speed changer period by a clutch unit from motor torque is current, the preliminary election of another gear range, to be switched to the gear range of preliminary election from current gear range with can not interrupting tractive force subsequently.For this reason, transmission input shaft is preferably made up of jointly two concentric axles, that is, is made up of the hollow shaft with built-in solid shaft.
This double clutch is known by DE10116705A1.In order to operated clutch unit, two slave cylinder pistons or control piston mutually arranged with one heart are set in this clutch unit, i.e. slave cylinder piston and an outer slave cylinder piston in one.Interior slave cylinder piston and outer slave cylinder piston lead respectively in the cylindrical shell of a Ring-cylindrical.This with the slave cylinder of such mode and method construct also referred to as CSC (including concentric slave cylinders).Thus, these two cylindrical shells are arranged equally with one heart and are constituted slave cylinder and an outer slave cylinder in one, and its mode is, these two slave cylinder pistons are arranged axially to move relative to each other.
By the known annular of DE102005008662A1, concentric, be in a release bearing and act on the slave cylinder piston in being connected jointly form compact structural unit in a common housing respectively.When operating separative element, breaking force is delivered to the corresponding clutch unit of double clutch from the second slave cylinder piston be linked into such as being responsible for the first gear by that be arranged in side, slave cylinder piston nose face, corresponding release bearing.In order to avoid the transmission of rotational motion, especially from other clutch units of double clutch to the transmission the second slave cylinder piston, such as or the rotatably bearer ring of fixedly separated bearing, rotatably by the fixing at least the second slave cylinder piston of lever arm, this lever arm is supported on the shell surface of slave cylinder housing of separative element.
But slave cylinder piston causes the radial structure space of separative element to increase by fixing at the lever arm being arranged on separative element shell surface outside.
DE102009056899A1 rotates the solution of fixing slave cylinder piston or drag torque support device with disclosing structure space for not increasing separative element, and wherein drag torque support device works respectively between the piston and the casing.
But the shortcoming of this solution is, in the housing of separative element or double clutch-CSC, for each slave cylinder piston, a groove is installed.In the operation of double clutch-CSC, this can guided by these grooves, to be arranged on relay piston seal arrangement in tip side in cause damage, cause double clutch-CSC blow-by thus and reduce its life-span.
Therefore, task of the present invention is, realize a kind of have drag torque support device between slave cylinder piston and CSC housing, for the separative element of double clutch, and in CSC housing, do not introduce opening for this reason.
This task by have claim 1 feature, solve for the separative element of double clutch.Favourable configuration is provided by dependent claims.
There is the separative element being used for double clutch thus, the housing having multiple ring shell body wall by one forms, thus be provided with two annular rooms with one heart relative to the symmetry axis of this separative element, can axially movably arrange respectively in these rooms sealing one pressure chamber, the slave cylinder piston of ring, described slave cylinder piston prevents the rotary motion of this slave cylinder piston by the anti-rotation device be arranged between this slave cylinder piston and described housing/shell body wall.According to the present invention, attach troops to a unit at each and on the shell body wall of a slave cylinder piston, arrange a drag torque support device and be fixedly connected with this shell body wall.During this drag torque support device and corresponding slave cylinder piston are in and act on and being connected.
Favourable improvement project regulation of the present invention, drag torque support device has at least one radial expansion portion, and this extension is embedded in processing at least one groove same in slave cylinder piston.Distributing to improve power, the periphery of drag torque support device installing multiple radial expansion portion yes favourable, these radial expansion portions can form interlocking with equal number being arranged on the groove in piston.
Form a fixed connection advantageously between shell body wall and slave cylinder piston, by means of pyrocondensation, compression or bonding drag torque support device to be installed on shell body wall.
Favorable structure regulation of the present invention, drag torque support device is made up of metal or nonmetallic material.
The present invention is illustrated in detail below by an embodiment and the accompanying drawing of attaching troops to a unit.
Accompanying drawing illustrates:
Fig. 1 illustrates according to separative element of the present invention with sectional drawing, has two slave cylinder pistons be in stress-free final position;
Fig. 2 illustrates the exploded view of the separative element according to Fig. 1.
Fig. 1 illustrates separative element 1 with sectional drawing, and this separative element is arranged on unshowned transmission input shaft in the assembled condition with one heart.This separative element comprises a housing 2, this housing can by plastics, metal or nonmetallic material form.Be provided with two room/grooves mutually extended with one heart in the housing, can axially movably lead respectively a slave cylinder piston 3,4 in these two room/grooves, thus the slave cylinder piston 3,4 of these annulars is also arranged mutually with one heart.In order to the sealing of pressure chamber, each slave cylinder piston 3,4 is provided with seal arrangement 5,6 in tip side, and these seal arrangements are respectively by packing holder 7, and 8 are connected with slave cylinder piston.At the other end, the release bearing 9,10 that each slave cylinder piston 3,4 and acts on the unshowned operating unit of a sub-clutch of double clutch connects.In order to avoid the drag torque of being drawn by driver is by release bearing 9,10 are delivered to two pistons 3, on 4, be provided with the ring as drag torque support device 11,12, these rings are such as by means of its inwall 11b, the pyrocondensation of 12b, bonding, compress and shell body wall 2a, 2b is fixedly connected with.These drag torque support devices 11,12 are respectively arranged with at least one radial expansion portion 11a, 12a.By means of these radial expansion portions 11a, 12a, drag torque support device 11,12 be separately positioned on piston 3, the groove 3a in 4,4a is in interlocking, thus prevents piston 3 thus, and 4 rotate when drag torque occurs.
Fig. 2 illustrates separative element 1 with exploded view.Can find out from this figure which position all components are interconnected in as the geometrical shape of part and they.Thus, first can find out that housing 2, two pistons 3,4 with two annular groove are encased in these two grooves.In addition, can find out two drag torque support devices 11,12, these drag torque support devices also do not have and corresponding shell body wall 2a in this drawing, and 2b is fixedly connected with.This connection such as can by means of the inwall 11b of drag torque support device 11,12 as described in FIG, and 12b pyrocondensation, to corresponding shell body wall 2a, 2b realizes.Can be clear that completely in this drawing and be arranged on drag torque support device 11, the radial expansion portion 11a on 12,12a, these extensions are arranged on the periphery of drag torque support device 11,12 in this embodiment respectively opposedly.Can see with radial expansion portion 11a, 12a overlap equally, be arranged on piston 3, the groove 3a in 4,4a.
Drag torque support devices 11,12 formed by these and be arranged on piston 3, the groove 3a in 4,4a, can realize a kind of anti-rotation device not needing opening in housing 2.
