Description

[Technical Field]

[0001] The present invention relates to a system for a motor vehicle having a lubricant passage and a coolant passage, and also to a motor vehicle having such a system. [Background technology]

[0002] In a vehicle, two or more components typically receive a fluid, such as a lubricant. The fluid is also typically temperature-controlled. To this end, each component typically has its own associated supply and infrastructure. This increases the installation space required and also increases the number of components required. Summary of the Invention [Problem to be solved by the invention]

[0003] The present invention aims to provide an improved or at least alternative embodiment of a system for a motor vehicle and a motor vehicle comprising such a system, which overcomes the drawbacks of the solutions known in the prior art. In particular, the present invention aims to provide an embodiment of the system and the motor vehicle which is characterized by increased efficiency and / or more cost-effective production and / or reduced installation space requirements. [Means for solving the problem]

[0004] According to the invention, this object is solved by the subject matter of the independent claims. Advantageous embodiments are the subject matter of the dependent claims.

[0005] Thus, the present invention is based on the broad idea of ​​providing a modular system for a vehicle having a reservoir for lubricant and coolant flowing along different flow paths, with two delivery devices and three coolers attached to the reservoir, with at least one flow path integrally molded into the reservoir, through which each corresponding flow path passes. By forming the flow paths within the reservoir, the flow path resistance is reduced, and thus the pressure loss within the system is reduced. This improves the efficiency of the system and the corresponding vehicle. Furthermore, since fewer components are required in the system to supply the corresponding vehicle parts, the system requires less installation space, making the system and the corresponding vehicle more cost-effective.

[0006] According to the concept of the present invention, the system, and thus the module, has two reservoir sections attached to each other, hereinafter also referred to as the upper and lower reservoir sections, which form a reservoir. Three flow paths for lubricant, particularly oil, hereinafter also referred to as lubricant passages, run through the reservoir. Thus, a first lubricant passage, a second lubricant passage, and a third lubricant passage run through the reservoir. Two flow paths for coolant, hereinafter also referred to as coolant passages, also run through the reservoir to cool the lubricant flowing along the lubricant passages. Thus, a first coolant passage and a second coolant passage run through the reservoir, fluidly separated from the lubricant passages. Two separate lubricant sump sections are molded into the lower reservoir section. The reservoir has corresponding inlets and outlets for each lubricant passage and each coolant passage. Thus, the reservoir has a first reservoir lubricant inlet connection and a first reservoir lubricant outlet connection for the first lubricant passage, through which the first lubricant passage passes. The reservoir also has a second reservoir lubricant inlet connection and a second reservoir lubricant outlet connection for the second lubricant passage, through which the second lubricant passage passes. The reservoir also has a third reservoir lubricant inlet connection and a third reservoir lubricant outlet connection for the third lubricant passage, through which the third lubricant passage passes. The reservoir also has a first reservoir coolant inlet connection and a first reservoir coolant outlet connection for the first coolant passage, through which the first coolant passage passes. The reservoir also has a second reservoir coolant inlet connection and a second reservoir coolant outlet connection for the second coolant passage, through which the second coolant passage passes. The system further has corresponding delivery devices for the first lubricant passage and the second lubricant passage, respectively, which are attached to the reservoir. Thus, the system has a first delivery device for the first lubricant passage and a second delivery device for the second lubricant passage. The reservoir also has two corresponding fluid connections for each delivery device, hereinafter also referred to as pump connections. Thus, the reservoir has two first fluid pump connections for the first delivery devices, to which the first delivery devices are fluidly connected, and which deliver lubricant along the first lubricant passage during operation.The reservoir further includes two fluidic second pump connections for second delivery devices to which the second delivery devices are fluidly connected, and which deliver lubricant along the second lubricant passages during operation. The system also includes a cooler attached to the reservoir for each lubricant passage. Thus, the system includes a first cooler for the first lubricant passage, a second cooler for the second lubricant passage, and a third cooler for the third lubricant passage. Each cooler has an inlet, hereinafter also referred to as a cooler lubricant inlet, for receiving lubricant, and an outlet, hereinafter also referred to as a cooler lubricant outlet, for discharging lubricant.

[0007] Each cooler also has an inlet, hereinafter also referred to as a cooler coolant inlet, for receiving coolant and an outlet, hereinafter also referred to as a cooler coolant outlet, for discharging coolant. The reservoir has a corresponding reservoir lubricant outlet for each cooler lubricant inlet and a corresponding reservoir lubricant inlet for each cooler lubricant outlet, with corresponding lubricant passages passing through each cooler. The reservoir also has a corresponding reservoir coolant outlet for each cooler coolant inlet and a corresponding reservoir coolant inlet for each cooler coolant outlet, with coolant fluidically separated from the lubricant passages flowing through each cooler during operation. Thus, the lubricant flowing through each cooler along the corresponding lubricant passage is cooled by the coolant during operation. Here, at least one flow passage is formed in the reservoir. The corresponding lubricant passage or coolant passage defined by the flow passage passes through each flow passage.

[0008] Here, the term "molded" to the reservoir advantageously means that each channel is formed entirely inside the reservoir, which means in particular that the reservoir itself forms at least one channel and / or that no other parts are present besides the reservoir to form the at least one molded channel.

[0009] It is conceivable that at least one of the at least one flow channel is formed in the reservoir by both reservoir parts. Advantageously, each flow channel formed by both reservoir parts has a flow channel part in one reservoir part that is open in a direction away from the other reservoir part and is closed by the other reservoir part to form the flow channel. Thus, a flow channel in the lower reservoir part has a flow channel part that is open towards the upper reservoir part and is closed by the upper reservoir part so that the flow channel is formed, or vice versa.

[0010] At least one of the at least one flow channel is preferably molded into one of the reservoir parts, so that the flow channel is entirely molded into the corresponding reservoir part, which means in particular that the reservoir part itself forms the at least one flow channel and / or that no other parts are present besides the reservoir part to form the at least one molded flow channel.

[0011] In principle, at least one channel can be molded into each of both reservoir parts.

[0012] Conveniently, at least one channel is molded into at least the upper reservoir portion.

[0013] Each channel is preferably molded into the upper reservoir section, thus simplifying the manufacture of the system.

[0014] The reservoir portions can each be made from any material.

[0015] Preferably, each reservoir part is made from a metal or alloy, for example aluminium. Similarly, each reservoir part can be made from a plastic, for example a polyamide, in particular a fibre-reinforced polyamide, in particular PA 66 GF 35 HS.

[0016] Advantageously, at least one of the at least one flow passages, preferably each flow passage of the reservoir, is molded into the corresponding reservoir section during injection molding of the reservoir section. This means that the reservoir section is manufactured by injection molding, and at least one insert is placed in the corresponding mold during injection molding, which is inserted into the corresponding mold and then removed, so that the at least one insert molds the at least one flow passage into the reservoir section after injection molding. In this way, the at least one flow passage is molded into the corresponding reservoir section by means of such an insert, also known as a core. This allows for a particularly cost-effective and simple production of the system.

[0017] It is conceivable here that the at least one insert remains in the corresponding reservoir portion, i.e. becomes part of the reservoir portion, and likewise the at least one insert can be removed from the reservoir portion after injection molding.

[0018] The reservoir portion may be formed in any manner.

[0019] In a preferred embodiment, the lower reservoir portion is formed in the shape of a deep container, and the upper reservoir portion is formed in the shape of a plate and placed on top of the lower reservoir portion. In this way, the upper reservoir portion is placed on top of the lower reservoir portion in the form of a lid.

[0020] In a preferred embodiment, at least one of the channels, and advantageously each channel, is molded into the upper reservoir section. In this way, since the channels are preferably molded into one of the reservoir sections, the manufacture of the reservoir and therefore the system is simplified and more cost-effective. If the upper reservoir section is also formed in a plate-like shape, the flow resistance in the at least one channel is further reduced, thereby increasing efficiency.

[0021] Advantageously, the pump connection is formed in the lower reservoir portion and the delivery device is attached to the lower reservoir portion.

[0022] In principle, each cooler may be configured in any way.

[0023] Advantageous is an embodiment in which at least one, and preferably each, of the coolers is configured as a plate cooler, so that each cooler can be attached to the reservoir in a simple and compact manner.

[0024] It is considered advantageous to have an embodiment in which at least one of the coolers, and preferably each cooler, is attached to the upper reservoir portion by being located on a face of the upper reservoir portion facing away from the lower reservoir portion, wherein the upper reservoir portion has a reservoir lubricant outlet, a reservoir lubricant inlet, a reservoir coolant outlet, and a reservoir coolant inlet.

[0025] In an advantageous embodiment, the first reservoir lubricant inlet connection is formed in the lower reservoir part, and the first reservoir lubricant outlet connection is formed in the upper reservoir part and faces away from the first reservoir lubricant inlet connection.

[0026] According to an advantageous variant, the second reservoir lubricant inlet connection is formed in the lower reservoir part, and the second reservoir lubricant outlet connection is advantageously formed in the upper reservoir part and is preferably located on the same plane as the second reservoir lubricant inlet connection. Advantageously, the second reservoir lubricant outlet connection and the second reservoir lubricant inlet connection are parallel to each other.

[0027] Advantageously, the third reservoir lubricant inlet connection and the third reservoir lubricant outlet connection are formed in the upper reservoir part and are arranged on the same face of the reservoir. Preferably, the third reservoir lubricant inlet connection and the third reservoir lubricant outlet connection are parallel to each other.

[0028] In an advantageous embodiment, the first reservoir coolant inlet connection and the first reservoir coolant outlet connection are formed in the upper reservoir part and are located on different faces of the reservoir.

[0029] According to an advantageous embodiment, the second reservoir coolant inlet connection and the second reservoir coolant outlet connection are formed in the upper reservoir part and are arranged on different faces of the reservoir.

[0030] Preferably, the first reservoir coolant inlet connection and the second reservoir coolant outlet connection are parallel to each other.

[0031] Advantageously, the second reservoir coolant inlet connection and the first reservoir coolant outlet connection are parallel to each other.

[0032] In practice, the reservoir has two faces facing away from each other. Thus, the reservoir has a first face and a second face facing away from the first face. The reservoir also has a third face and a fourth face facing away from the third face. The first and second faces extend in an oblique or transverse direction relative to the third and fourth faces, preferably transversely. Preferably, the third and fourth faces connect the first and second faces to each other.

[0033] Advantageously, the pump connection is arranged on a first face of the reservoir. Advantageously, the second reservoir coolant inlet connection and the first reservoir coolant outlet connection are arranged on a second face of the reservoir. Advantageously, the first reservoir coolant inlet connection and the second reservoir coolant outlet connection, as well as the first reservoir lubricant inlet connection, are arranged on a third face of the reservoir. Advantageously, the second reservoir lubricant inlet connection and the second reservoir lubricant outlet connection, as well as the first reservoir lubricant outlet connection, are arranged on a fourth face of the reservoir.

[0034] In principle, the coolant passages may pass through the reservoir fluidly separately from one another.

[0035] It is also conceivable that the coolant passages cross over the reservoir, in particular the upper reservoir part, so that a flow of coolant between the coolant passages can occur within the reservoir.

[0036] In an advantageous embodiment, the system has for at least one of the lubricant passages a corresponding temperature sensor and for each temperature sensor a corresponding connection, hereinafter also referred to as sensor connection, is provided in the reservoir.

[0037] In a preferred embodiment, the system has corresponding temperature sensors for the first and second lubricant passages. Accordingly, the system has a first temperature sensor for the first lubricant passage. The reservoir has a first sensor connection for the first temperature sensor, through which the first temperature sensor enters the first lubricant passage, particularly between the first reservoir lubricant inlet connection and the first delivery connection. The system also has a second temperature sensor for the second lubricant passage. The reservoir has a second sensor connection for the second temperature sensor, through which the second temperature sensor enters the second lubricant passage, particularly between the second reservoir lubricant inlet connection and the second delivery connection.

[0038] In a preferred embodiment, the first lubricant passage leads to the first reservoir, and the first reservoir lubricant inlet connection is fluidly connected to the first reservoir, so that the first lubricant passage runs from the first reservoir lubricant inlet connection through the first cooler, through the first reservoir, and to the first reservoir lubricant outlet connection.

[0039] In an advantageous embodiment, the second lubricant passage passes through the second reservoir, and the second reservoir lubricant inlet connection is fluidly connected to the second reservoir, such that the second lubricant passage runs from the second reservoir lubricant inlet connection through the second cooler, through the second reservoir, and to the second reservoir lubricant outlet connection.

[0040] This system is employed in automobiles to supply lubricants to different parts.

[0041] Preferably, each lubricant passage serves to supply a lubricant, in particular oil, to a corresponding component.

[0042] Preferably, the vehicle comprises a first electric machine, a second electric machine and a transmission, each of which is supplied with lubricant via the system.

[0043] Each electric machine may be an electric motor.

[0044] Advantageously, a first lubricant passage passes through the first electric machine, a second lubricant passage passes through the second electric machine, and a third lubricant passage passes through the transmission.

[0051] For example, the system 1 shown in FIGS. 1 to 10 is used as a module 25 of an automobile 100 illustrated in FIG.

[0052] In the illustrated exemplary embodiment, the motor vehicle 100 comprises, in addition to the system 1, a first electric machine 101, a second electric machine 102, and a transmission 103, each of which is supplied with a lubricant, e.g., oil, via the system 1 during operation. For this purpose, passages 5, 6, and 7 corresponding to the lubricant run through the system 1, respectively, and are also referred to below as lubricant passages 5, 6, and 7. The first lubricant passage 5 runs through the system 1 and the first electric machine 101. The second lubricant passage 6 runs through the system 1 and the second electric machine 102. Furthermore, the third lubricant passage 7 runs through the system 1 and the transmission 103.

[0053] As is clear from Figures 2 to 10, the system 1 has two reservoir portions 2, 3 attached to each other, which will hereinafter also be referred to as the upper reservoir portion 2 and the lower reservoir portion 3. The upper reservoir portion 2 and the lower reservoir portion 3 combine to form the reservoir 4 of the system 1. As is particularly clear from Figure 4, the lower reservoir portion 3 in the illustrated exemplary embodiment is in the form of a deep container. The upper reservoir portion 2 is plate-shaped and is attached on top of the lower reservoir portion 3. The upper reservoir portion 2 closes the lower reservoir portion 3 in the manner of a lid.

[0054] The lubricant passages 5, 6, and 7 extend through the reservoir 4. In the system 1, the lubricant flowing along each of the lubricant passages 5, 6, and 7 is cooled during operation. For this purpose, two coolant flow paths 8 and 9 extend through the reservoir 4, fluidly separated from the lubricant passages 5, 6, and 7. These flow paths 8 and 9 will hereinafter also be referred to as coolant passages 8 and 9. Thus, a first coolant passage 8 and a second coolant passage 9 extend through the reservoir 4. As can be seen particularly from FIG. 5, the lower reservoir section 3 is molded with two separate lubricant reservoirs 10, namely, a first reservoir 10a and a second reservoir 10b. For each of the lubricant passages 5, 6, and 7, the reservoir 4 has a corresponding inlet 11 for receiving the lubricant and a corresponding outlet 12 for discharging the lubricant. Hereinafter, the inlet 11 will also be referred to as the reservoir lubricant inlet connection 11, and the outlet 12 will also be referred to as the reservoir lubricant outlet connection 12. To this end, the reservoir 4 has, for the first lubricant passage 5, a first reservoir lubricant inlet connection 11a and a first reservoir lubricant outlet connection 12a through which the first lubricant passage 5 passes. The reservoir 4 also has, for the second lubricant passage 6, a second reservoir lubricant inlet connection 11b and a second reservoir lubricant outlet connection 12b through which the second lubricant passage 6 passes. The reservoir 4 also has, for the third lubricant passage 7, a third reservoir lubricant inlet connection 11c and a third reservoir lubricant outlet connection 12c through which the third lubricant passage 7 passes. The reservoir 4 also has, for each of the coolant passages 8, 9, a corresponding inlet 13 for receiving coolant and a corresponding outlet 14 for discharging the coolant. In the following, the inlet 13 will also be referred to as a reservoir coolant inlet connection 13, and the outlet 14 will also be referred to as a reservoir coolant outlet connection 13. Thus, for the first coolant passage 8, the reservoir 4 has a first reservoir coolant inlet connection 13a and a first reservoir coolant outlet connection 14a, through which the first coolant passage 8 communicates. The reservoir 4 also has a second reservoir coolant inlet connection 13b and a second reservoir coolant outlet connection 14b, through which the second coolant passage 9 communicates. Furthermore, the system 1 has a delivery device 15 for delivering lubricant to the first lubricant passage 5 and the second lubricant passage 6 along the corresponding lubricant passages 5, 6, respectively.Thus, the system 1 has a first delivery device 15a for the first lubricant passage 5 and a second delivery device 15b for the second lubricant passage 6. Here, each delivery device 15 is attached to the reservoir 4. The reservoir 4 has, for each delivery device 15, a corresponding fluid connection 16, 17 to which the delivery device 15 is fluidly connected for delivering lubricant. These connections 16, 17 are also referred to hereinafter as pump connections 16, 17. Thus, the reservoir 4 has, for the first delivery device 15a, two fluidic first pump connections 16 into which the first delivery device 15a is fluidly connected and into which the first delivery device 15a is inserted in the illustrated exemplary embodiment, such that the first lubricant passage 5 leads to the first pump connections 16 and the first delivery device 15a delivers lubricant along the first lubricant passage 5 during operation. Furthermore, the reservoir 4 has two fluidic second pump connections 17 to which the first delivery devices 15b are fluidly connected and into which the second delivery devices 15b are inserted in the illustrated exemplary embodiment, such that the second lubricant passage 6 leads to the second pump connections 17 and, during operation, the second delivery devices 15b deliver lubricant along the second lubricant passage 6. As can be seen in particular from Figure 2, the pump connections 16, 17 are formed in the lower reservoir part 3 in the illustrated exemplary embodiment. Also, the delivery devices 15 are attached to the lower reservoir part 3 in the illustrated exemplary embodiment.

[0055] Additionally, system 1 includes a corresponding cooler 18 attached to reservoir 4 for cooling the lubricant flowing through each of lubricant passages 5, 6, and 7. Accordingly, system 1 includes a first cooler 18a for first lubricant passage 5, a second cooler 18b for second lubricant passage 6, and a third cooler 18c for third lubricant passage 7. Each cooler 18 includes a cooler lubricant inlet for receiving lubricant, a cooler lubricant outlet for discharging lubricant, a cooler coolant inlet for receiving coolant, and a cooler coolant outlet for discharging coolant, all of which are not shown. As can be seen, for example, in FIG. 4, reservoir 4 includes a corresponding reservoir lubricant outlet 19 for each cooler lubricant inlet and a corresponding reservoir lubricant inlet 20 for each cooler lubricant outlet, such that each cooler 18 is connected to its corresponding lubricant passage 5, 6, and 7. Furthermore, the reservoir 4 has a corresponding reservoir coolant outlet 21 for each cooler coolant inlet and a corresponding reservoir coolant inlet 22 for each cooler coolant outlet so that coolant fluid separated from the lubricant passages 5, 6, 7 flows through each cooler 18 during operation, and so that lubricant flowing along the corresponding lubricant passages 5, 6, 7 during operation is cooled by the coolant in each cooler 18. As can be seen particularly from Figure 3, each cooler 18 is formed as a plate cooler 26 in the illustrated exemplary embodiment.

[0056] As can be seen particularly from Figure 4, the reservoir 4 has at least one flow passage 24 molded therein. In the illustrated exemplary embodiment, the at least one flow passage 24 is molded in at least one of the reservoir sections 2, 3. In the illustrated exemplary embodiment, at least one flow passage 24 for at least one of the flow passages 5, 6, 7, 8, 9 is molded in the upper reservoir section 2. Thus, at least one flow passage 24 is molded in the upper reservoir section 2, and a corresponding lubricant passage 5, 6, 7 or coolant passage 8, 9 passes through each flow passage 24. Therefore, the system 1 can be constructed in a simple manner and with fewer individual parts. Furthermore, the at least one flow passage 24 reduces pressure losses in the corresponding flow passages 5, 6, 7, 8, 9.

[0057] The reservoir portions 2, 3 are advantageously manufactured from a light metal, such as aluminum, or from a plastic, such as a fiber-reinforced polyamide, in particular PA 66 GF 35 HS, where each flow channel 24 can be formed in the upper reservoir portion 2 in that the upper reservoir portion 2 is injection molded, each flow channel 24 being formed during injection molding using an insert (not shown), which is removed from a corresponding injection mold (not shown) after injection molding, and each flow channel 24 is molded into the upper reservoir portion 2.

[0058] 2 and 3, the cooler 18 in the illustrated exemplary embodiment is disposed on the face of the upper reservoir portion 2 facing away from the lower reservoir portion 3 and is attached to the upper reservoir portion 2. The upper reservoir portion 2 therefore has a reservoir lubricant outlet 19, a reservoir lubricant inlet 20, a reservoir coolant outlet 21, and a reservoir coolant inlet 22.

[0059] 2 and 4, in the illustrated exemplary embodiment, a plurality of passages 24 are molded into the upper reservoir portion 2. In the illustrated exemplary embodiment, the upper housing portion 2 has a first passage 24a for the first lubricant passage 5, which includes the first reservoir lubricant outlet connection 12a. Additionally, the upper housing portion 2 has a second passage 24b for the second lubricant passage 6, which includes the second reservoir lubricant outlet connection 12b. A third passage 24c for the third lubricant passage 7 has the third reservoir lubricant inlet connection 11c, and a fourth passage 24d for the third lubricant passage 7 has the third reservoir lubricant outlet connection 12c. Additionally, the upper housing portion 2 has a fifth passage 24e and a sixth passage 24f for the first and second coolant passages 8 and 9, where the fifth passage 24e has the first reservoir coolant inlet connection 13a and the sixth passage 24f has the second reservoir coolant outlet connection 14b. The upper housing portion 2 also has a seventh flow passage 24g for the first coolant passage 8 and an eighth flow passage 24h for the second coolant passage 9. The seventh flow passage 24g has a first reservoir coolant outlet connection 14a. The eighth flow passage 24h has a second reservoir coolant inlet connection 13b.

[0060] As can be seen particularly from FIG. 2, the first coolant passage 8 communicates with the fifth flow path 24e via the first housing coolant inlet connection 13a and with the first housing coolant outlet connection 14a via the first cooler 18a and the seventh flow path 24g. The second coolant passage 9 communicates with the eighth flow path 24h via the second housing coolant inlet connection 13b and with the second housing coolant outlet connection 14b via the second cooler 18b and with the sixth flow path 24f. As can be seen particularly from FIGS. 2 and 6, in the illustrated exemplary embodiment, the sixth flow path 24f and the seventh flow path 24g are further fluidly connected to the fifth flow path 24e and the eighth flow path 24h, respectively, via the ninth flow path 24i in the upper housing portion 2. As can be seen from FIG. 6, the ninth flow path 24i opens on the surface facing the lower reservoir portion 3. There, a corresponding protrusion 30 of the lower reservoir part 3, shown in particular in Figures 5 and 7, engages with the ninth flow passage 24i, forming a drain opening 31 for draining the produced cooling liquid.

[0061] In the illustrated exemplary embodiment, the first lubricant passage 5 leads into the first reservoir 10a. Further, the first reservoir lubricant inlet connection 11a is fluidly connected to the first reservoir 10a. Thus, the first lubricant passage 5 leads from the first reservoir lubricant inlet connection 11a through the first cooler 18a, through the first reservoir 10a, to the first reservoir lubricant outlet connection 12a. Further, in the illustrated exemplary embodiment, the second lubricant passage 6 leads into the second reservoir 10b, and the second reservoir lubricant inlet connection 11b is fluidly connected to the second reservoir 10b. Thus, the second lubricant passage 6 leads from the second reservoir lubricant inlet connection 11b through the second cooler 18b, through the second reservoir 10b, to the second reservoir lubricant outlet connection 12b.

[0062] The reservoir 4 has two surfaces 27 that face outward from each other. Thus, the reservoir has a first surface 27a and a second surface 27b that face outward from each other. Furthermore, the reservoir 4 has a third surface 27c and a fourth surface 27d that face outward from each other. In the illustrated exemplary embodiment, the third surface 27c and the fourth surface 27d extend in a direction that is substantially intersecting with the first surface 27a and the second surface 27b. The pump connections 16, 17 are arranged on the first surface 27a.

[0063] According to Fig. 2, the first reservoir lubricant inlet connection 11a in the illustrated exemplary embodiment is formed in the lower reservoir part 3. Also, the first reservoir lubricant outlet connection 12a in the illustrated exemplary embodiment is formed in the upper reservoir part 2 and faces away from the first reservoir lubricant inlet connection 11a. As can be seen in particular from Fig. 4, the second reservoir lubricant inlet connection 11b in the illustrated exemplary embodiment is formed in the lower reservoir part 3. Also, the second reservoir lubricant outlet connection 12b is arranged in the upper reservoir part 2 and, together with the second reservoir lubricant inlet connection 11b, is arranged on the fourth face 27d of the reservoir 4.

[0064] As is particularly clear from FIG. 4, the third reservoir lubricant inlet connection 11c and the third reservoir lubricant outlet connection 12c are formed in the upper reservoir part 2 and are arranged on the second surface 27b of the reservoir 4.

[0066] As can be seen more clearly from, for example, FIG. 4, the third reservoir lubricant inlet connection 11c and the third reservoir lubricant outlet connection 12c are formed in the upper reservoir portion 2 and are located on the second reservoir surface 27b.

[0067] In the illustrated exemplary embodiment, as is particularly clear from FIG. 2 , the system 1 has corresponding temperature sensors 28 for the first lubricant passage 5 and the second lubricant passage 6, respectively. Accordingly, the system 1 has a first temperature sensor 28a for the first lubricant passage 5 and a second temperature sensor 28b for the second lubricant passage 6. Furthermore, the reservoir 4 has a corresponding connection 29 for each temperature sensor 28, which connection will also be referred to as sensor connection 29 hereinafter. Accordingly, the reservoir 4 has a first sensor connection 29a for the first temperature sensor 28a, via which the first temperature sensor 28a enters the first lubricant passage 5. In the illustrated exemplary embodiment, the first temperature sensor 28a enters the first lubricant passage 5 between the first reservoir lubricant inlet connection 11a and the first delivery device 15a. The reservoir 4 also has a second sensor connection 29b for a second temperature sensor 28b, via which the second temperature sensor 28b enters the second lubricant passage 6. In the illustrated exemplary embodiment, the second temperature sensor 28b enters the second lubricant passage 6 between the second reservoir lubricant inlet connection 11b and the second delivery connection 15b.

The system further includes seals 33 between the reservoir sections 2, 3 and between the cooler 18 and the upper reservoir section 2. In the illustrated exemplary embodiment, the reservoir sections 2, 3 are attached to each other and to the cooler 18 by screws 34, as well as to the delivery device 15 attached to the reservoir 4.

[0069] 1, at least one of the coolant passages 8, 9 may pass through a cooling circuit 104.
