Definitions
- the invention relates to a transmission for a drive train of a motor vehicle, having a housing and a differential unit arranged in a receiving space of the housing.
- the transmission is more preferably implemented as a hybrid transmission and more preferably also has an electric machine.
- EP 3 534 042 A1 discloses a drive train of a motor vehicle with a transmission.
- a collection container is provided in a housing of the transmission, which stores lubricating oil.
- a supply path is further provided in this case for supplying the lubricating oil, which is supplied by a differential gear mechanism during reverse running of the automobile.
- an outlet passage which is connected to an outlet port of an oil pump, is also connected to the catch tank.
- a gear wheel of the differential unit is used in order, during operation, to convey a hydraulic medium from a collecting space located on an underside of the housing, viewed in relation to a planned installation position in the gravitational field, in the circumferential direction to one facing away from the underside / opposite upper side of the housing, wherein the gear wheel is encased by at least one guide element fixed to the housing and the at least one guide element is designed in such a way that the hydraulic medium conveyed by the gear wheel in the circumferential direction is at least partially axially conveyed at a (specific) circumferential area of the gear wheel in the direction of a Lubrication and / or cooling demand point within the receiving space and / or forwards in the direction of a gear space arranged adjacent to the receiving space.
- the at least one guide element has a disk-shaped side wall area arranged (directly) axially next to the gear wheel and/or has an outer wall area that overlaps/projects over a toothing of the gear wheel radially from the outside (axially).
- the gear wheel is encapsulated/surrounded as tightly as possible by the guide element.
- the guide element is further preferably made of a plastic material.
- the at least one guide element on the peripheral region (of the gear wheel) forms/has a blade section (in the sense of a deflection/diverting blade), which blade section causes a deflection of part of the hydraulic medium conveyed by the gear wheel in the circumferential direction in the axial direction .
- This also further simplifies the construction of the guiding element.
- the blade section is designed in such a way that it deflects part of the hydraulic medium in the axial direction both in a first direction of rotation and in a second direction of rotation (opposite to the first direction of rotation). This ensures that the hydraulic medium is distributed independently of a selected gear of the transmission and thus in particular both in a forward gear and in a reverse gear.
- the at least one guide element has/forms a trough for storing a specific quantity of hydraulic medium axially next to the gear wheel.
- the diverted hydraulic medium is temporarily stored and distributed as specifically and efficiently as possible to the points to be lubricated / cooled.
- the trough is hydraulically connected via a connecting channel to a roller bearing supporting a shaft component of the differential unit. This results in a particularly efficient lubrication of the corresponding roller bearings.
- the at least one guide element is designed in such a way that a second partial quantity of the hydraulic medium conveyed in the circumferential direction from the underside to the upper side is conveyed further in the circumferential direction beyond the circumferential region causing the axial deflection of a first partial quantity of the hydraulic medium.
- part of the hydraulic medium is preferably also forwarded to a region of the gear wheel of the differential unit which is in meshing engagement with another gear wheel. The efficiency of the lubricant/coolant supply is further increased.
- the at least one guide element is provided with an opening that penetrates its blade section in the circumferential direction.
- the production of the guide element is kept as simple as possible. If a guide element is arranged axially on both sides of the gear wheel, that is to say if one guide element is arranged on each axial side of the gear wheel, the hydraulic medium is distributed in an even more targeted manner.
- a first guide element forms a side wall area and a blade section and, on the other hand, a further, second guide element has, in particular, a side wall area, with the side wall area of the second guide element being arranged on a side of the gearwheel that is axially remote from the side wall area of the first guide element is.
- the gear wheel is encapsulated as far as possible on all sides.
- the two guide elements have a common vane section, which vane section is designed in such a way that it deflects the hydraulic medium conveyed in the circumferential direction by the gear wheel in both (opposite) axial directions.
- the blade section can preferably be designed in such a way that it distributes the hydraulic medium equally in the axial direction, ie deflects the same quantity/volume flow both to the first axial side and to the second axial side. This allows the lubrication / cooling to take place in a targeted manner.

- the differential unit 4 has a gear wheel 5 that forms the input of the differential unit 4 and is therefore also referred to as an input wheel. 2, for example, also shows the corresponding output shafts 25a, 25b, which are further connected to the wheels of the motor vehicle, for forming the output of the differential unit 4.
- the directional information used in the present case is to be seen on an axis of rotation 26 of the gear wheel 5 of the differential unit 4 .
- Under axial / axial direction is thus a direction along / parallel to the axis of rotation 26, under radial / radi- ale direction is to be understood as a direction perpendicular to the axis of rotation 26 and under circumferential direction as a direction along a circular line running concentrically around the axis of rotation 26 .
- the transmission 1 has the further transmission unit 14 .
- the transmission unit 14 can be designed, for example, as a switchable transmission unit/a multi-speed transmission/a manual transmission and can thus be coupled to the gear wheel 5 of the differential unit 4 via a number of different gear ratios.
- the transmission 1 is preferably designed as a hybrid transmission and therefore, in a particularly preferred embodiment, has an electric machine, not shown here for the sake of clarity, for driving the motor vehicle.

- An output/rotor of the electrical machine is preferably connected to the differential unit 4 by means of the transmission unit 14 .
- the gear chamber 13 accommodating the gear unit 14 forms a collecting chamber 7 .
- This collecting chamber 7 is designed to form an underside 6 of the housing 2 in relation to the intended installation position of the transmission 1 in the gravitational field.
- the collection space 7 also referred to as an oil sump, is therefore used during operation to collect and temporarily store a certain amount of oil/amount of hydraulic medium and is therefore provided on the underside 6 .
- the differential unit 4 is accommodated in a receiving space 3 of the housing 2 , which receiving space 3 is spatially separated from the collection space 7 and thus also from the gear space 13 .
- the receiving space 3 also forms a (first) gear space, which is separated from the (second) gear space 13 accommodating the gear unit 24 .
- the collection space 7 is hydraulically connected to the receiving space 3 via a passage opening 27 tied together.
- a collection cavity 28 is formed on an underside 6 of the receiving space 3 , also seen in relation to the intended installation position and considering the acting gravitational field, which collection cavity 28 is connected directly to the collection space 7 via the passage opening 27 .
- the gear wheel 5 protrudes radially into this collecting cavity 28 .
- a hydraulic medium flowing in through the through-opening 27 is immediately conveyed further in the circumferential direction from the collecting cavity 28 when the gearwheel 5 is rotating.
- the gear 5 dips in particular with its toothing 15 (external toothing) during operation directly into the hydraulic medium located in the collecting well 28 and takes it with it in the circumferential direction.
- the gear wheel 5 is encased by at least one guide element 9, 10, in this case even two.
- a first guide element 9 is arranged essentially on a first axial side of the gear wheel 5, while a second guide element 10 is arranged essentially on a second axial side of the gear wheel 5 opposite the first axial side.
- the guide elements 9 , 10 are supported/attached to the housing 2 .
- Both guide elements 9, 10 are preferably made of a plastic material, more preferably by injection molding.
- the first guide element 9 has a (first) side wall area 14a, which is arranged directly on the first axial side of the gear wheel 5.
- the first guide element 9 also has an outer wall area 16 which covers/overhangs the gearwheel 5 radially from the outside in the axial direction. That outer wall area 16 directly forms a vane section 17 on a specific peripheral area 11 (viewed in the circumferential direction), which vane section 17 is used according to the invention to to deflect / divert / distribute the hydraulic medium conveyed by the gear 5 in the circumferential direction from the underside 6 to an upper side 8 of the housing 2 in the axial direction on both sides of the gear 5 .
- the second guide element 10 also has a (second) side wall area 14b which is arranged axially opposite to the first side wall area 14a on the side of the gear wheel 5 and thus to the second axial side of the gear wheel 5 . Furthermore, the second guide element 10 has an outer wall region 30 running in the circumferential direction, which runs further in the circumferential direction (seen in a first direction of rotation of the gearwheel 5 ) following/behind the blade section 17 . This outer wall area 30 of the second guide element 10 also covers the gear wheel 5 in the axial direction from a radial outside.
- a (first) trough 18a is formed on the first guide element 9 .
- This trough 18a is used directly to collect and temporarily store a portion of hydraulic medium that is diverted axially (towards the first axial side of the gear wheel 5) by the blade section 17 during operation.
- the trough 18a is closed towards the underside 6 in particular.
- the first guide element 9 completely forms this trough 18a.
- the second guide element 10 also forms a (second) trough 18b, which serves to temporarily store the hydraulic medium that is deflected axially (towards the second axial side of the gear wheel 5) by the blade section 17.
- This second trough 18b is formed both by the second guide element 10 and by the housing 2.
- the troughs 18a, 18b are correspondingly directly hydraulically connected to points 12 requiring lubrication and/or cooling, here in the form of roller bearings 21a, 21b, 21c, 21d.

- the first trough 18a is connected directly to a first roller bearing 21a via a connecting channel 19 (FIG. 3).
- the second trough 18b is further connected via a connecting channel 19 directly to a further roller bearing 21b.
- the two (first and second) roller bearings 21a, 21b support the output shafts 25a, 25b relative to the housing 2.
- the troughs 18a, 18b are more preferably still hydraulically connected to other bearings of the transmission 1.
- Further connecting channels 19 connect the respective trough 18a, 18b with at least one further (third or fourth) roller bearing 21c, 21d.
- the third roller bearing 21 c and the fourth roller bearing 21 d preferably serve to support a gear wheel 29 that is directly in mesh with the gear wheel 5.
- a second embodiment of the transmission 1 according to the invention is illustrated.
- the blade section 17 is designed in such a way that it distributes the hydraulic medium conveyed in the circumferential direction equally in both axial sides.
- the hydraulic medium conveyed in the circumferential direction, which is deflected by the blade section 17, is thus deflected 50%/half to the first axial side of the gear wheel 5/supplied to the first trough 18a and 50%/half 18b to the second axial side of the gear 5 deflected / fed to the second trough 18b.
- the blade section 17, which is attached to the first guide element 9 is formed directly, also for deflecting hydraulic fluid to the second guide element 10 is used.
- the hydraulic medium that is deflected by the blade section 17 to the second axial side of the gear wheel 5 preferably flows through the second guide element 10 axially through a corresponding through-opening 31 (FIG. 3).
- a web 23 (reinforcing web) which is still present in FIG. 1 is dispensed with.
- the blade section 17 can in principle be provided with a corresponding through-hole/an opening 22 penetrating the blade section 17 in the circumferential direction, which serves to convey a subset of the material conveyed in the circumferential direction through the gear wheel 5 Let hydraulic fluid through in the circumferential direction and supply it to corresponding further areas of the transmission 1, for example directly to the area of tooth contact between the gear wheel 5 and the gear wheel 29.
- the blade section 17 is designed in such a way that it causes an axial deflection of the hydraulic medium conveyed by the gear wheel 5 not only when the gear wheel 5 rotates in the first direction of rotation, but also in an opposite, second direction of rotation.
- the blade section 17 is shaped in such a way that it forms a corresponding rear chamber 32, which in turn catches part of the hydraulic medium conveyed in the second direction of rotation and in the axial direction to the troughs 18a, 18b, preferably equal Share, forward.
- An axial passage 24 through the web 23 can also be seen in FIG.
- another rib 33 is preferably designed specifically to collect the hydraulic medium conveyed in reverse gear/when the gear wheel 5 rotates in the second direction of rotation and from there forward it in the axial direction.
- the size of the opening 22 is preferably selected in such a way that a proportion of 20% of the hydraulic medium conveyed at a specific speed of the gear wheel 5 flows in the circumferential direction past the blade section 17 or through it via the opening 22 is conveyed further and 80% is diverted axially.
