Definitions
- Multi-plate clutch Hybrid unit and motor vehicle
- the invention relates to a multi-plate clutch having at least one oil chamber, wherein the oil space is limited by a first wall element and a second wall element, wherein the wall elements are arranged movable against each other, and a sealing element for sealing the opening between the first wall element and the second wall element.
- multi-plate clutches are essentially three oil chambers known: the pressure chamber, the pressure compensation chamber and the lamella package receiving fin space.
- the pressure chamber and the pressure equalization chamber, also called compensation chamber, are located in multi-plate clutches, which are hydraulically actuated. In principle, however, other oil rooms may also be present.
- the oil compartments are usually limited by two or more wall elements. If the wall elements are rigidly connected, they can be welded together. With mutually movable wall elements, such as the piston and a plate carrier, a sealing element must be arranged between the wall elements, which covers the opening between the wall elements. It is known, for example, to arrange the wall elements for a distance substantially parallel and to store and clamp the sealing element between these two wall sections of the wall elements. It is known that the sealing element can be L-shaped. One of the legs is then facing the oil room. The other protrudes into the opening. Usually, one of the wall elements is designed to be fixed in the axial direction, while the other is arranged to be movable in the axial direction. The sealing element is either attached to one of the wall elements or mounted on one of the wall elements.
- the sealing element has at least one radial distance and at least one axial section, wherein both sections have at least one side facing the oil chamber.
- the sealing element may in principle have more than one radial section and one axial section, but these are to be provided at least. In the general version, this merely means that there are two sections which are arranged at an angle to one another and which close the opening. The included angle is usually between 90 ° and 135 °, advantageously, the sections can be arranged at right angles.
- the sealing element can have exactly two sides, which face the pressure chamber.
- the sealing element may have exactly three sides which face the pressure chamber.
- the sealing element may have exactly four sides which face the pressure chamber. It is assumed that the main axes, sides of protrusions, etc. are not counted.
- the oil space can be delimited by at least one further wall element.
- Prerequisite for the invention are only two mutually movable wall elements.
- the wall of the oil space need not be limited to these two wall elements.
- the first wall element may extend at least partially in the axial direction.
- the first wall element extends partially in the axial direction and partially in the radial direction. It can therefore limit two sides of the oil space.
- the axial part of the sealing element advantageously adjoins the axial part of the wall element.
- the axial portion defines itself as extending at least more in the axial direction than in the radial direction. It does not have to be exactly in the axial direction nor must it be straight in full length. For example, it may contain a level.
- the second wall element may extend at least partially in the radial direction.
- the wall elements of a lamellar coupling As well as the plate carrier and the piston often bends.
- the piston may be formed, for example, S-shaped or double S-shaped.
- the sealing element in the case of the same component can in principle adjoin a radial or an axial section.
- a wall element therefore does not have to extend continuously exclusively in the axial or radial direction.
- At this radial part of the wall element advantageously includes the radial portion of the sealing element.
- the radial portion of the sealing element can be arranged to be movable relative to the second wall element.
- the axial section of the sealing element can be arranged to be movable relative to the first wall section.
- the sealing element is attached to any of the wall elements. But then the sealing element is freely centered and must therefore be attached nowhere anywhere during assembly. This eliminates at least one assembly step and the mounting of the sealing element is also easier compared to the situation when it is attached to a wall element.
- the oil space may be a pressure chamber for receiving pressurized oil for actuating the multi-plate clutch.
- a pressure chamber usually that space is referred to, which adjoins a piston and this shifts during filling for actuation.
- the first wall element may be formed on a piston of the multi-disc clutch.
- the first wall element is arranged at least in sections in the axial direction. This can easily be the case with the piston.
- the sealing element or the axial section of the sealing element is arranged radially within the first wall element.
- the second wall element may be formed on a radial wall section.
- the radial wall portion may be formed on a housing, for example, the clutch housing, M Osenlamellenlism and / or on the converter cover.
- the radial wall portion is at the same time a housing portion, a portion of the Au nchlamellenyess and a portion of the converter cover. Then, this wall or wall element fulfills a triple function, which is why the multi-plate clutch or the drive train receiving the multi-plate clutch builds very short in the axial direction.
- the sealing element at the end of the axial portion and / or radial portion may have a sealing element facing the wall element.
- sealing lips are basically known, they effect an improved seal by the sealing element.
- the sealing element may preferably have a holding section projecting into the opening.
- the holding portion is an additional portion to the axial portion and radial portion. It can basically be structured as desired and serves to temporarily hold the sealing element in position. More precisely, the holding portion serves to fix the sealing element in the open state of the multi-plate clutch, ie in the disengaged position, in the radial and / or axial direction. This is made possible by the functional principle of self-centering.
- the sealing element When filling the pressure chamber with pressure oil, the sealing element is pressed against the piston as the first wall element and against the Au nchlamellen phenomenon as a second wall element. It is centered in the right position all by itself. In this position, the distance between the outer plate carrier and the piston is greatest, the holding section is exposed.
- the positioning is due to the fact that in the pressure chamber, there is a greater pressure than outside of the pressure chamber regardless of whether outside is also an oil chamber or a room filled with air. Due to this pressure difference, the sealing element is pressed against the
- the piston When opening the clutch, the pressure is removed from the pressure oil.
- the piston is brought by a return spring in the disengaged position. It moves the Piston on the outer disc carrier too.
- the holding portion is designed such that it is clamped between the piston and outer disk carrier before the pressure in the pressure chamber is so small that the sealing element would slip in the radial direction due to gravity.
- the sealing element is in position over the entire operating cycle of the coupling, without it having to be fastened to the outer disk carrier or to the piston.
- the holding section accordingly has at its free end a region which is fixed in the disengaging position of the multi-plate clutch.
- this may be a thickening, preferably an elastic thickening.
- it may also be an elastic projection or extension, which is designed tube-shaped ren.
- the holding portion may have a sealing lip.
- the axial portion of the sealing element is arranged radially within the first wall element. This makes it clear that the sealing element does not rest on the first wall element.
- first wall element and the second wall element are arranged axially movable relative to each other.
- a radial mobility is additionally or alternatively possible.
- the first wall element is movable in the axial direction and the second wall element fixedly arranged in the axial direction.
- the mobility to each other thus comes about by the mobility of the first wall element.
- the sealing element can be arranged carrier-free to the oil chamber.
- the sealing element is not stored as known from the prior art, for example by the radial or axial side or this section rests on a wall element.
- the sealing element is annular. This is common but should be repeated for the sake of completeness.
- the sealing element may comprise a stiffening element.
- This can be designed in particular L-shaped.
- the stiffening element may be T-shaped.
- the stiffening element may be partially or entirely covered with rubber or at least provided at its ends with sealing lips to achieve the sealing effect.
- the sealing element may have at least one radially outwardly disposed, extending in the axial direction comb. This serves to center the seal over the piston or the first wall element.
- several combs may be present in the circumferential direction of the sealing element.
- a comb is a projection extending in the axial and radial directions.
- the invention relates to a hybrid unit with a part of the electric machine and a multi-plate clutch.
- the hybrid unit is characterized in that the multi-plate clutch is designed as described.
- the part of the electric machine may be the rotor. This is preferably non-rotatably connected to the disk clutch, in particular the outer disk carrier of the multi-disk clutch.
- the invention relates to a motor vehicle with a multi-plate clutch and / or hybrid and / or a hybrid unit.
- the motor vehicle is characterized in that the multi-plate clutch and / or the hybrid unit are designed as described.
- Fig. 6 is a sealing element in a fourth embodiment
- Fig. 7 is a sealing element in a fifth embodiment.
- the transmission can be designed as an automatic transmission, dual-clutch transmission, manual transmission or in any other desired manner.
- a hybridized drive train is shown purely by way of example, with a main point of view being on the separating clutch 3 between the internal combustion engine 2 and the electric motor 4 or the internal combustion engine 2 and the following section of the drive train.
- the separating clutch 3 can also be packed with other couplings of the drive train in a mounting unit, as is the case for example in the so-called triple-clutch.
- the multi-plate clutch described can be used in all places, including dual clutches or multi-plate clutches and brakes in an automatic transmission.
- the embodiment of a disconnect clutch 3 according to one of the embodiments of the present invention is particularly valuable since any drag torque losses reduce the range of a purely electric drive.
- FIG. 2 shows a hybrid unit 7, comprising at least one rotor 8 and a separating clutch 3.
- the separating clutch 3 comprises an outer disk carrier 9, a Inner disk carrier 10 and a disk set 12 arranged therebetween with outer disks 14 and inner disks 16.
- the inner disk carrier 10 is located on the input side with respect to the internal combustion engine 2. It is mounted on the oil supply hub 20 via a roller bearing 18.
- the coupling has three oil chambers, namely the pressure chamber 22, the compensation chamber 24 and the fin space 26. These are three separate oil chambers. These can be completely sealed against each other, but it can also be a connection between the compensation space 24 and the fin space 26 exist.
- the pressure chamber is delimited by three wall elements 28, 30 and 32.
- the wall elements 28, 30 and 32 are those portions of each unit that limit the pressure chamber 22.
- the Wandele- element 28 is thus a part or a portion of the piston 34
- the wall member 30 is a part of the converter cover 36 and the Au ndlamellenlys 10
- the wall member 32 is a part of the ⁇ lzuGermannabe 20.
- the piston 34 thus includes more sections or parts next to the wall element 28, as is the case with the converter cover 36 and the ⁇ lzu Foodnabe 20.
- the wall elements 28, 30 and 32 themselves have subunits, these are also referred to below as sections. This defines the following structure: An oil space is delimited by at least two, in particular several, wall elements.
- the wall elements are parts of a component or a separate component. Subunits in the wall elements are called sections.
- the piston has, for example, a first, radial portion 34a. This is followed by a bending section 34b and then an axial section 34c. As axial sections, the piston has the sections 34c, 34f, 34j and 34n. The bending portions are the portions 34b, 34c, 34e, 34g, 34i, 34k and 34m. Radial sections are sections 34a, 34d, 34h, 34I.
- the sections 34d to 34n are sections of the wall element 28.
- the sealing element 40 is arranged floating and self-centering and will be presented in more detail below in several embodiments.
- FIG. 3 shows the sealing element 40 in a first embodiment in detail.
- the sealing element 40 is located in the radial direction on the outside of the pressure chamber 22 and is placed on the wall elements 28 and 30 for sealing the opening 38. In the radial direction, it is supported by the holder 48.
- the sealing element 40 consists of a stiffening element 50 and a rubber coating 52, on which two sealing lips 54, 56 are formed.
- the stiffening element 50 and thus also the sealing element 40 has two legs 58 and 60. This results in a radial portion 51 and an axial portion 53 of the sealing element 40th
- the leg 58 abuts on the wall member 28 via the sealing lip 54, more precisely on the axial section 34f, and the second leg 60 on the wall element 30.
- the sealing element 40 accordingly has six sides 62, 64, 66, 68, 70 and 72. Of the six sides, the sides 64, 68, 70 and 72 facing the pressure chamber, while the sides 62 and 68 lie on the pressure chamber-opposite side. In actuation position of the separating clutch 3, the pressure chamber is filled with pressure oil, this then automatically presses the sealing element 40 against the wall elements 28 and 30.
- the sides 70 and 72 are end faces and from the surface of lesser effect than the surfaces 64 and 68 with respect to the pressing action of the pressure oil.
- the holder 48 When emptying the pressure chamber in the open state of the separating clutch 3, the holder 48 holds the sealing element 40 in the radial direction.
- FIG. 4 shows the sealing element 40 in a second embodiment.
- the reference symbols relating to the sections on the piston have been omitted for the sake of clarity.
- the sealing element 40 has a second radial section 74, which results from a corresponding extension of the reinforcing element 50. This is configured T-shaped in this embodiment.
- the sealing lips 76 and 78 are now the sealing lips 76 and 78. The sealing lips 54 and 76 ensure a tightness against the pressure chamber 22.
- the sealing lip 78 has a different function.
- the sealing element 40 can be fixed in the radial direction by means of the sealing lip 78 in the opened state of the separating clutch 3 by the wall element 28 and the wall element 30 or the piston 34 and the converter cover 36.
- the holder 48 is superfluous, whereby the manufacture and assembly of the separating clutch 3 is further simplified.
- Figure 5 shows a further embodiment of the sealing element 40.
- the stiffening element 50 is again designed L-shaped. However, in comparison to FIG. 3, it is arranged reversed in the radial direction.
- the first radial portion 51 consists only of the sealing lip 76 and an extension of rubber.
- the stiffening element 50 stiffens only the axial region 53 and the second radial region 74.
- the holding effect of the radial region 74 has already been described with reference to FIG.
- FIG. 6 shows a further embodiment of the sealing element 40.
- the reinforcing element is in turn designed L-shaped and serves to stiffen the radial region 51 and the axial region 53. Sealing lips 54 and 76 are located at the ends of the legs 58 and 60. Their effect has already been described.
- a holding section 80 is provided, which consists of a projection of the rubber material. The projection 80 and the holding portion 80 is thickened at its end 82 and since it is made of rubber is elastic. Thereby, the holding portion 80 can be fixed well by the piston 34 upon disengagement.
- FIG. 7 shows a further development to FIG. 6, which can also occur in the other embodiments.
- at least one projecting ridge 84 may be provided on the side 62 of the axial portion 53 remote from the oil space. This serves to center the seal over the piston.
- a plurality of combs 84 may be present.
- a comb is a projection extending in the axial and radial directions, as shown in FIG. This has a very limited extent in the circumferential direction, it can be several millimeters wide. Since the sealing element 40 is no longer fixed to the wall element 30, an overdetermination of the piston 34, which still has the sealing element 44 on the side of the compensation chamber 24, can be avoided.
