Description

The invention relates to an oil supply system consisting of several Components such as Oil pump, oil filter, oil cooler as well corresponding oil connection lines between the components, exists and to supply an engine of a motor vehicle with oil, especially for lubrication.

Due to the large number of individual components of such a Oil supply system, the assembly on the engine is relatively complex. In addition, the large number of connecting lines the overall structure of the engine or engine compartment relatively confusing, which makes maintenance of the engine or its components is difficult. Additionally requires the large number of oil lines an elaborate seal.

The present invention addresses the problem with the help of simple constructive measures for an oil supply system a possibility of the type mentioned specify with the help of the assembly of the individual components of the oil supply system on the engine simplified and the structure the engine compartment can be made clearer.

This problem is solved by an oil module according to the characteristics of claim 1 solved.

The invention is based on the general idea of the individual Components of the oil supply system and their functions to form a separate assembly, the oil module. Such an oil module can be preassembled to be completed and within the framework of a Final assembly as a complete unit quickly and easily Motor can be mounted. For the, especially automated, Assembly line production of an engine is a significant one Simplification. It is also with the help of such Oil module possible, the individual components of the engine oil circuit, such as. Oil pan, oil pump, oil cooler, oil filter to arrange space-saving and clear, so that in this way the overall structure of the engine or engine compartment can be simplified.

Such an oil module is essentially thereby realized that an oil pan of the motor vehicle engine with Help a side part laterally over an end face of the Extended beyond the motor and along this face becomes. In this way, sufficient installation and mounting space created to aggregate the oil circuit, such as. Oil pump, oil cooler, oil filter, on or in the oil pan or to arrange the side part extending this. Furthermore it is possible to connect the individual aggregates as well as connections between the oil module and engine during to integrate the production into the side part or into the oil pan, so that no additional connecting lines and associated seals are required.

In a particularly advantageous embodiment, this can Side part of the oil pan on the front side of the engine Be open and only through the Mounting on the motor can be closed by its front side. Appropriate sealants are used for oil-tight sealing of the oil pan side part on the front of the engine intended. This measure enables a particularly compact Design for the oil module, with additional seals for connections to the motor can be omitted.

By designing the side part of the oil pan in the form of a at least partially covering the front of the engine Half-shell, the front of the engine becomes functional integrated in the oil module so that the oil side between the engine and oil pan or its side part only a seal, preferably in the extent of the side part, is necessary.

According to a preferred embodiment, the Coolant pump designed in a corresponding manner open on one side be, with the result that the coolant pump only functional after mounting on the front of the motor becomes. Again, the number of seals required reduced. Other important advantages of such Construction is the material savings that can be achieved, consequently a reduced weight and reduced installation dimensions.

According to a preferred embodiment of the invention Oil module can the side part, the coolant pump and a housing of the oil filter made in one piece be. This measure enables a particularly cost-effective Production of the oil module, a production as Plastic component is preferred.

According to another embodiment of the invention Oil module can the side part and the oil filter housing be made in one piece. This way it is possible a different material (e.g. plastic) for this assembly to use as for example for the coolant pump (e.g. die-cast aluminum).

In a corresponding manner, an embodiment in which the Coolant pump and the oil filter housing made in one piece are also enable material optimization.

According to another embodiment of the invention Oil module can be a cylindrical tube of the oil filter housing formed as a separate component and thus in particular to be manufactured as an aluminum die-cast component in this way to meet special material requirements can.

A variant is also possible in which the tube mentioned of the oil filter housing and the coolant pump as one piece Component are made and to achieve particularly high Strength values consist in particular of die-cast aluminum.

To integrate the oil cooler into the oil module, it can be opened different ways can be arranged. For example the oil cooler is only on the side part of the oil pan arranged, its connections and lines in Side part are integrated.

In an alternative embodiment, the oil cooler partly on the side part of the oil pan and partly on the housing the coolant pump arranged. Here are the connections and lines on the coolant side in the coolant pump housing and integrated on the oil side in the side panel. Such Embodiment is particularly advantageous if the plastic side part and the coolant pump housing is made of aluminum. Because in this Case can at least the coolant-side connections of the Oil cooler with the help of axial seals that are relative need high pressure forces to be sealed, whereby a compensation of assembly and manufacturing tolerances is possible. Another variant can be used for the same reasons be designed such that only one connection of the oil cooler with a connection integrated in the side panel connected is.

The connections with which the oil cooler is integrated into the oil module are preferably designed as plug connections, to simplify assembly. The Plug connections to be provided with radial seals that effective even with relatively low fastening forces Effect sealing. This is particularly advantageous if one of the components, for example the side part, is off Plastic is made.

According to a particularly advantageous embodiment of the oil module according to the invention is the oil pump of the oil circuit arranged in the oil pan or in the side part of the oil pan, which makes the oil module particularly compact and no special seals for the oil pump and its lines required are. The oil pump is expediently with the help of a drive shaft, preferably the crankshaft, of the engine e.g. via a toothing within the oil pan or driven within the side part.

The above can be used to drive additional units Drive shaft of the engine through the side panel of the oil pan be carried out sealed. For example, the drive shaft drives in a known manner, a fan wheel of the motor and an alternator.

To assemble the separate individual components of the oil module to simplify the entire oil module, they become necessary connections and connections preferably as Plug connections formed.

The individual components of the oil module, such as oil pan, side part the oil pan, oil filter with cover, tube and one the bottom section containing connections, and coolant pump can be made of different materials, preferably Plastic or die-cast aluminum. Furthermore can the various components of the oil module in different combinations made in one piece be. With the help of the given diverse The oil module can be varied in different ways Requirements such as the prevailing forces and moments, the chosen manufacturing process, the required material properties, be adjusted. In addition, you can the manufacturing costs, the assembly properties, maintenance options, the flexibility and expansion options as well as the weight of the oil module on special requirement profiles be coordinated.

The following variants are mentioned as examples:

The side part of the oil pan is in one piece with the oil filter Made of plastic while the coolant pump is made Die-cast aluminum is made. With the help of a plug connection a secondary flow of the coolant pump is branched off and connected to corresponding lines of the side part. The oil cooler is mounted on the side part and connected with corresponding cables in the side part. All necessary connections and lines are included already integrated in the side panel. To increase the Stability, the housing of the oil filter can also be attached to the housing be attached to the coolant pump.

Starting from this embodiment can increase the Strength of the oil filter, its tube as a separate component trained and be made of die-cast aluminum.

In a further development of the latter variant, the Tube of the oil filter housing in one piece with the housing of the Coolant pump made of die-cast aluminum. This This measure makes an additional fastening of the oil filter housing unnecessary on the coolant pump housing.

In another embodiment, the oil filter or its Housing and the coolant pump in one piece from die-cast aluminum and the side part of the oil pan is made of plastic. Such an embodiment can be particularly high Loads on the oil filter housing may be required. However, the lid of the oil filter is preferably made of plastic for reasons of weight and cost. In such an embodiment, the oil cooler is preferred partly on the housing of the coolant pump and Part attached to the side part. These are for the oil cooler necessary lines and connections in appropriate Partly in the housing of the coolant pump and Part integrated in the side part of the oil pan. Here is a Preferred embodiment, in which the coolant side Connections in the coolant pump housing and the oil side Connections in the side part of the oil pan are integrated to one consequent separation of the coolant circuit from the oil circuit receive.

Another variant of the oil module according to the invention sees front, the side panel, the oil filter and the coolant pump one-piece, especially made of plastic or die-cast aluminum to manufacture. This variant enables a special inexpensive production with minimal assembly effort.

According to another variant are the side part and oil filter made in one piece and survive like that a separate coolant pump connected to a plug connection made of aluminum or plastic. Doing so for unity from side part and oil filter and different for the coolant pump Plastics can be chosen, which in particular in terms of their resistance to oils and coolants differentiate.

1 and 2 has a preferred embodiment an oil module 1 according to the invention essentially the outer contour of an end face of a not shown Motors of a motor vehicle. On the bottom the engine is one with dashed lines Oil pan 2 shown, to which one extends along the end face of the engine extending side part 3 of the oil pan 2nd is connected sealed. The side part 3 is there provided with several mounting openings 4, with their Help the side part 3, especially by screwing it on the end of the motor can be attached.

The side part 3 is in its lower area as a half-shell trained that down to the oil pan 2 back and side is open towards the front of the motor. For sealing opposite the front of the engine is in the area of the circumference this half-shell according to FIG. 2, a sealing element 5 arranged.

Inside the side part 3 or within its half shell an oil pump 6 is arranged, in the embodiment shown via a toothing 7 from a drive shaft 8, in particular the crankshaft, of the engine is driven. The oil pump 6 has a suction line protruding into the oil pan 2 9 and a pressure line 10.

The drive shaft 8 of the motor is shown in FIG. 1 by the side part 3 of the oil pan 2 performed and can on this Place as a drive for other units of the engine, such as e.g. Alternator, water pump and fan wheel, serve. Advantageously can already in the manufacture of the oil module 1 the oil pump 6 with its lines 9 and 10 and the Section of the drive shaft 8, which drives the oil pump 6 serves and is carried out by the side part 3, in the side part 3 mounted or integrated. In this way can the portion of the drive shaft shown in the figures 8 e.g. with the help of a plug connection to a corresponding counterpart emerging from the front of the motor the drive or crankshaft of the engine can be connected be.

That from the oil pump 6 via the suction line 9 from the oil pan 2 sucked oil is through the pressure line 10 and through a in the side part 3 integrated, invisible line of Oil side of an oil cooler 11 supplied. This is outside mounted on the side part 3, in particular by screwing, the oil and coolant side connections of the Oil cooler 11 and the corresponding, on or in the side part 3rd provided connections preferably as plug connections are trained.

The heated to the oil cooler 11 via the oil pump 6 heated or hot oil leaves the oil cooler 11 again cooled one integrated in the side part 3 and therefore not visible Line and is supplied to an oil filter 12 in which the cooled oil is cleaned of dirt.

In the exemplary embodiment, the oil filter 12 has a through Lid 13 lockable housing 16, which consists of a cylindrical Tube 14 and one containing the oil connections Floor element 15 is formed. In the exemplary embodiment, this is Oil filter housing 16 made in one piece with the side part 3, with the necessary connecting cables in the side part 3 are integrated, which in contrast to separate Connection lines no additional seals of these connections are necessary.

The contaminated supplied from the oil cooler 11 to the oil filter 12 Oil leaves this cleaned again in the side element 3 integrated drain line 17 with a corresponding inlet pipe in the front of the engine communicates. The heated and possibly contaminated Oil collects again in the oil pan 2 on the underside of the motor.

For the coolant supply of the oil cooler 11 there are again corresponding ones Coolant lines integrated in the side part 3, that communicate with a flow of coolant. At the Oil module 1 according to the invention is particularly advantageous a coolant pump 101 to a structural unit put together. This is a particularly compact construction achieved in which a housing 102 of the coolant pump 101 is open on one side and only by its assembly on the front of the motor is closed. This measure causes a material saving and thus a weight saving and enables cheaper production. In addition, there is only one along the circumferential line of the housing 102 running sealing element necessary to the engine seal on the coolant side against the coolant pump 101.

The coolant pump 101 is not, for example, via a Drive belt shown driven by the drive shaft 8 and works in a known way to supply the engine and other units to be cooled with coolant. To a particularly compact structure for the invention Achieving oil modulus is the main flow of the coolant circuit a secondary flow with the help of directly on the coolant pump housing 102 provided extension lines 108 and 109 branched. These extensions 108 and 109 and the corresponding connections in the side part 3 that over in the side part 3 integrated lines to the oil cooler 11 connecting the coolant bypass are advantageous designed as a plug connection.

3, the coolant pump 101 is a radial pump formed, with a corresponding one in the housing 102 Rotor 103 is indicated as a circle. The housing 102 is open on its housing side shown in plan view, i.e. the housing 102 is directly on with this side Corresponding unit, here on the front of the engine block of a motor vehicle, connected and with through Openings 104 screws attached to this. The open side of the housing 102 forms a pressure side Port 105 (hereinafter referred to as the pressure side Main terminal 105).

On the housing 102, as shown in FIG. 3 on the left side, a suction-side connection 106 designed as a connection piece (hereinafter referred to as the suction-side main connection 106) arranged. This suction-side main connection 106 forms e.g. a supply line from the coolant of the coolant circuit. over an additional connection 107, corresponding to FIG. 3 above, the Suction side of the coolant pump 101, for example from a thermostat coming coolant supplied.

In the housing 102 is, according to FIG. 3 below, additional to the pressure-side main connection 105, a pressure-side auxiliary connection 108 formed, the one with the pressure-side interior of the housing 102 is communicatively connected. In corresponding Way is at another location of the housing 102, in the embodiment shown in the area of the suction side Connection piece 106 a suction-side auxiliary connection 109 formed, which in turn with the suction side of the coolant pump 101 is communicatively connected.

These extension lines 108 and 109 each clearly show one smaller flow area than the main connections 105 and 106. This ensures that only a comparatively small bypass flow through these bypasses is branched off and the main stream the rest Coolant circuit available essentially unchanged stands. Since the auxiliary connections 108 and 109 directly on the housing 102 of the coolant pump 101 are arranged Secondary flow, the pressure difference generated by the coolant pump 101 to disposal.

The auxiliary connections 108 and 109 are cylindrical receptacles 110 and serve according to FIG. 4 in each case as a socket of a plug connection. As another component this connector is on the pressure side extension 108, corresponding to FIG. 4 on the left, a cylindrical connecting piece 111 provided at its axially free end is designed as a connector 112. At its other end is the connector 111 with one in this view Connected unit, not shown, directly or indirectly connected. The connecting piece 111 forms on his Inside a communicating with the unit to be cooled Connection opening 125.

At the suction side connection 109, corresponding to FIG. 4 on the right, is in contrast to this as a further connector component a connecting pipe 113 shown that formed as a plug 112 at each of its two axial ends is.

The seal between connection piece 111 and pressure side Extension 108 or between connecting pipe 113 and suction-side extension 109 is made by a radially acting sealing ring 114, which in a in the area of Plug 112 in the connecting piece 111 or in the connecting tube 113 recessed annular groove 115 is introduced.

The secondary connections 108 and 109 run in the axial direction parallel to each other, making it easy to attach the coolant pump 101 to an additional unit or vice versa. In the exemplary embodiment according to FIG. 4 is a preferred embodiment with approximately the same Height-ending sleeves or receptacles 110 reproduced.

Due to the spatially relatively close to each other 108 and 109, by their parallel alignment and their design as plug connections is also a Modular design for components to be connected easier, the connecting lines to be connected to each other in the module elements are integrated. By the chosen The individual components can be plugged in without Join the external cables to form a complete module.

In another embodiment corresponding to FIG. 5 the secondary connections 108 and 109 are each designed as connecting pieces 116, which serve as the plug of the connector. This Plug 116 of the secondary connections 108 and 109 act with corresponding receptacles designed as sleeves 117 of the unit to be connected, here the side part 3 the oil pan 2 or the oil cooler 11 together. Here too there is a seal between connector 116 and sleeve 117 guaranteed by a sealing ring 118, which in this case to a recessed area 119 at the axially free end of the connector or plug 116 is pushed.

In a special embodiment, corresponding to FIG. 6 the receptacle 110 of the secondary connection designed as a sleeve 108 with the connecting piece 111 of the additional unit connected, being an exemplary embodiment of the pressure-side extension 108 was selected in the same This configuration can, however, also be carried out on the suction side Extension port 109 may be provided. From the connected Unit or the side part 3 is a connection area in FIG. 6 120 shown, in this special version as a separate intermediate piece connected to the unit is trained. The axially free end of the connecting piece 111 is again designed as a plug 112, in which If the seal is made with a sealing ring 121, the axially free on a withdrawn area 122 End of the connector 111 or plug 112 pushed is.

The housing 102 of the coolant pump usually exists 101 made of metal, especially die-cast aluminum, while the connected unit, e.g. the oil module 1 or Side part 3, can be made of plastic. Since the mentioned components exposed to large temperature differences and because these different materials are different Having coefficient of thermal expansion, it can lead to relative movements come between these components. From Sleeve 110 and plug 112 formed connector can be Compensate for shifts in their axial direction.

In another, preferred variant there is accordingly 7 shows the plug connection between the coolant pump 101 and the connected unit from the secondary connection 108, a receptacle 123 and from the connecting pipe 113. Here too is the pressure side Extension 108 selected only for example. The one described Embodiment can also with the suction-side extension 109 can be realized. The receptacle 110 of the extension 108 and the recording 123 here again from one additional intermediate piece formed connection area 120 of the unit are designed as sleeves, in which the axial ends of the connecting tube designed as plugs 112 113 can be inserted. The sealing takes place through the radially acting sealing rings 114, which are ring-shaped circumferential grooves 115 are introduced.

In the state shown in FIG. 7, receptacles 110 and Recording 123 aligned with each other, so that too this connection shifts in the axial direction of the recordings 110 and 123 can compensate. But since both the coolant pump 101 as well as the unit (oil module 1) for example are fixed to an engine block 124, it can additionally also come to thermal expansion movements, their direction of movement not with the axial direction of the receptacle 110 and 123 coincides. Accordingly, the shown Change aligned alignment. So that there is no tension The early material fatigue arises between the components and therefore reduced component life result in the configuration according to the invention a tension-free relative movement between the Components. For this purpose the outside diameter of the connecting pipe 113 smaller than the inner diameter the receptacle 123 and the receptacle 110, so that the Connecting pipe 113 with play in the receptacles 110 and 123 can be introduced. This measure ensures between the Coolant pump 101 and the unit or between the auxiliary connection 108 of the coolant pump housing 102 and the connection opening 125 of the unit also adjustment movements in a direction that is not with the longitudinal axes of the shots 110 and 123 coincide.

These measures make a cardanic connector trained, the gimbal agility additionally is supported that the axial ends of the connecting tube 113 are rounded.

When designing this gimbal connector takes into account that the sealing rings 114 even at extreme Adjustment movements of the receptacles 110 and 123 against each other ensure a sealed connection.

To insert a plug into its associated socket simplify, are the receptacles designed as a sleeve provide a bevel at their axially free opening.

6 and 7 is only the pressure side port 108 is shown, however, both extensions 108 and 109 are preferably formed in the same manner.
