- the housings may advantageously be ring-shaped with respect to the drive shaft or have an annular wall region, so that an annular radial gap is respectively spanned between the housings and the drive shaft.
- the axially adjacent to each other housing can be arranged independently or advantageously have a fixed positional relationship and for this purpose be connected to each other.
- the drive shaft can be mounted by means of a bearing fixed to one of the housings. Under these conditions, the radial gaps are spatially well defined even under a rotational movement of the drive shaft and the areas to be sealed.
- a sealing element may be provided as sealing means, which is formed between the drive shaft, the first housing and the second housing. Both receiving spaces of the housing can thus be closed together by a single sealing element.
- the sealing element may be formed as a contact seal and be fixed with a fixing on one of the housing and further cooperate with a static sealing portion with the other housing and with a dynamic sealing portion with the drive shaft.
- the sealing element may be designed as a ring seal made of an elastic material with a reinforcing element.
- the sealing element can be designed as an axially open on one side hollow profile.
- a reinforcing element is advantageously a metallic reinforcing ring, in particular of a spring steel, which extends in a cross section of the sealing element from the fixing over the static sealing portion to the dynamic sealing portion.
- the dynamic sealing portion may comprise two sealing lips, which emanate from a common foot area.
- the reinforcing ring can extend up to a common foot region of the sealing lips.
- the drive shaft may be formed as an input or output shaft of a clutch and the first housing as a clutch housing of the clutch, wherein in the receiving space of the second housing, a power electronics unit is arranged.
- the coupling housing may comprise two axially joined housing shells, wherein at least one of the housing shells forms a portion of the second housing and wherein the second housing on the side facing away from the coupling has a lid and is closed by this.
- one of the housing shells may be formed as a radial wall element, which spatially separates the power electronics unit from an electric machine having a rotor and a stator, and wherein the stator carries a stator winding whose connection areas are guided through the radial wall element into the second receiving space and are connected to the power electronics unit.
- the drive module may more preferably comprise a carrier element on which the stator of the electric machine and the first and the second housing are fixed.
- the rotor of the electric machine may be connected to the input or output shaft of the clutch.
- Fig. 1 is an axial sectional view of a drive module
- FIG. 2 is a fragmentary enlarged view of the module of FIG. 1 with a sealing element inserted in the region of a radial gap;
- FIG. Fig. 3 is an individual view of the sealing element of Fig. 2 in an axial section.
- 1 shows a drive module 10 for a hybrid vehicle, which first comprises a drive shaft 12 rotatably mounted about an axis A, which represents the input shaft 14 of a separating clutch 16.
- the output shaft 18 of the clutch 16 is connected to a rotor 20 of an electric machine 22.
- the input shaft 14 may be operatively connected in a vehicle with the crankshaft of an internal combustion engine, so that when the clutch 16 is closed both drive units can initiate a drive torque to the wheels. With the clutch 16 open, the vehicle can be driven solely by the electric machine 22.
- the clutch 16 is presently designed as a form-locking coupling and comprises an electromagnetic actuator unit 24 and a coupling unit 26 with which the input and the output shaft 14, 18 are brought together with each other in rotational driving.
- the actuating unit 24 and the coupling unit 26 are housed together in a receiving space 28 of a substantially fluid-tight coupling housing 30.
- the clutch housing 30 is coaxially formed around the drive shaft 12, wherein between the elements, a radial gap 32 is clamped.
- the coupling housing 30 comprises two housing shells 30a, b which are joined axially to one another, the housing shell 30b enclosing the actuation unit 24 carrying a roller bearing 34 for supporting the input shaft 14.
- the coupling housing 30 has a housing opening 38 in the region of a return spring 36 of the actuating unit 24, so that the receiving space 28 is accessible via the radial gap 32 formed there.
- a lubricant in the receiving space 28, e.g. a low viscosity fluid through the housing opening 38 into the existing radial gap 32, pass the Wälzläger and distribute in an undesirable manner.
- the drive module 10 comprises, axially adjacent to the coupling 16 and to the coupling housing 30, a power electronics unit 40 which is housed in a housing. meraum 42 a further housing 44 is housed. At the same time, both housing shells 30a, b of the coupling 16 also form part of the housing 44 of the power electronics unit 40.
- the housing shell 30 a is simultaneously formed as a radial wall element 30 c, which spatially separates the power electronics unit 40 from the electric machine 22 with the rotor 20 and with the stator 21.
- the terminal portions 21 a of the stator winding 21 b of the stator 21 are guided through the radial wall member 30 c into the receiving space 42 and connected there to the power electronics unit 40.
- the housing 44 comprises, on the side facing away from the coupling 16, an annular disk-shaped cover 44a, which is inserted with an outer edge region including a sealing element 46 in a cylindrical portion of the radial wall element 30c and thus a circuit carrier 48 and electronic components 50 of the power electronics unit 40 against can close the environment substantially tight.
- a circuit carrier 48 and electronic components 50 of the power electronics unit 40 against can close the environment substantially tight.
- the cover 44a In the radially inner region of the cover 44a is supported axially on the housing shell 30b associated with both the clutch 16 and the power electronics unit 40.
- the housing 44 of the power electronics unit 40 is also annular and coaxially formed about the drive shaft 12, wherein between this and the drive shaft 12, a further radial gap 52 is spanned. 1, it can be seen that the receiving space 42 also forms a housing opening 54 in the form of an annular gap on an area facing the clutch housing 30, via which the receiving space 42 is accessible from the radial gaps 32, 52, so that, for example, foreign particles, oil mist, Humidity or the like can undesirably penetrate.
- a sealing means 56 is provided in a mutual abutment region of the two housings 30, 44, in particular at an interface of the radial gaps 32, 52, which in an axial viewing direction along the radial gaps 32, 52 access to the first and to the second housing opening 54 closes.
- the sealing means 56 is formed in the embodiment as a sealing member 58 which is formed between the drive shaft 12, the first housing 30 and the second housing 44 and inserted there. Both receiving spaces of the housing 30 can thus be jointly closed by a single sealing element 58 and reliably protected against the undesired entry of foreign particles or the escape of operating materials.
- the sealing element 58 is constructively designed as a contact seal and designed as a circumferential annular seal, which comprises a base body 60 made of an elastic material and a metallic reinforcing element 62.
- a cylindrical fixing section 64 is provided, which is firmly inserted into an inner cylindrical receiving region 301 on the coupling housing 30.
- the sealing element 58 has an outgoing from the fixing portion 64 C-shaped portion 66 which defined by a sealing bead 66a against a wall portion 441 a of the lid 44a is there and acts as a static sealing section. This extends from this further radially inward to cooperate with a dynamic sealing portion 68 with the drive shaft 12.
- the sealing element 58 is designed in the direction of the bearing 34 as an axially one-sided open hollow profile.
- a reinforcing element 62 is a reinforcing ring of a spring steel, which extends in a cross section of the sealing member 58 from the fixing portion 64 via the static sealing portion to the foot ß Scheme 68 a of the dynamic sealing portion 68.
- the drive module 10 further comprises a substantially cylindrical carrier element 70, on which the stator 21 of the electric machine 22 and the two housings 30 are fixed. This carrier element 70 can thus accommodate the coupling 16 with the input and the output shaft 18, the electric machine 22 with rotor 20 and stator 21 and the power electronics unit 40 while forming the drive module 10.
- the prefabricated module 10 can be inserted and mounted in a receiving housing, for example in the transmission bell of a gear change transmission.
