Definitions
- the invention relates to an oil collecting device for an internal combustion engine according to the features of the preamble of claim 1.
- an oil suction is provided with which the oil is supplied to the consumers again.
- Corresponding oil guide ribs are provided for the targeted return of the oil located in the flatter installation space section.
- the object of the invention is to design an oil collecting device for an internal combustion engine in such a way that, on the one hand, safe and rapid oil return from the consumers to the oil sump is ensured and, on the other hand, it is ensured that, even when the internal combustion engine is at an angle, the lubricating oil flows back from the deeper installation space section is prevented in the crankcase and / or in the flatter installation space section.
- These two functions are said to be related to manufacturing be integrated in a simple manner and therefore also cost-effectively in the oil collecting device.
- the insert which is designed separately from the oil collecting device, is designed on the one hand with an oil barrier required between the two installation space sections and also has oil return channels through which the oil flowing back from the cylinder head goes directly to below the oil level of the lubricating oil located in the lower installation space section.
- the insert consists of a middle part with an oil holding edge and an oil bulkhead and two side parts, in which oil pressure channels from the cylinder head are integrated.
- the insert part is advantageously made of plastic and thus contributes overall to a reduction in weight of the internal combustion engine.
- a plastic insert is easy to manufacture, e.g. by injection molding.
- 1 is a first perspective view of an oil collecting device
- Fig. 7 is a section along the line Vll-Vll in Fig. 3 and
- FIG 8 shows a two-stage oil pump used in the oil collecting device.
- An oil collecting housing 2 has an installation space section 4, which is referred to in the following as the first oil collecting space and in which the oil necessary for the lubricating oil supply of the internal combustion engine accumulates.
- An oil snorkel 6 is placed at its deepest point in the first oil collecting space 4, which leads via a first oil suction line 8 to the suction side of an oil pump 10.
- a second installation space 12 Arranged in the oil collecting housing 2 is a second installation space 12, which is referred to below as the second oil collection space and which is flatter than the first oil collection space 4.
- An oil snorkel 14 is also arranged at its lowest point in the second oil collection chamber 12, which is connected via a second oil suction line 16 to a second suction side of the oil pump 10 designed as a double pump
- a plastic insert 18 is inserted into the oil collecting housing 2, the structure of which is described in more detail below.
- the insert part 18 has a middle part 20 which, as shown in particular in FIGS. 2 and 3, separates the two oil collecting spaces 4, 12 from one another in the installed state.
- the middle part 20 has a first side wall 22 oriented towards the first oil collecting space 4, which is provided with a curved wall section 23 forming a bulkhead for the lubricating oil.
- This tongue and groove connection is additionally sealed by silicone or soft foam, since it is intended to prevent lubricating oil from the first oil collecting space when the motor vehicle is at an incline 4 arrives in the second oil collecting space 12.
- the first side wall 22 of the insert part 18 is designed such that the lubricating oil can flow from the first oil collecting space 4 under the central part 20, in particular when the engine is at an angle. This section of space is thus also used to hold the oil volume required for a reliable supply of lubricating oil.
- a top wall 26 of the central part 20 is lowered towards the center (see section line IV - IV in FIG. 3) of the oil collecting housing 2 and consists of two lowered partial surfaces 26a and 26b which merge into a straight partial surface 26c in the middle.
- the side edge 28 of the top wall 26, which is oriented towards the first oil collecting space 4, hereinafter referred to as the oil holding edge, serves as an oil barrier which prevents the lubricating oil from passing from the first oil collecting space 4 into the second oil collecting space 12 when the vehicle is traveling uphill.
- the second oil suction line 16 leading to the second oil collecting space 12 runs above the centrally aligned straight partial surface 26c.
- Two side parts 30 and 32 are integrally formed on the central part 20, in which part of the oil return channels leading from the cylinder head to the first oil collecting space 4 are integrated.
- the two side parts 30 and 32 have oil return openings 34, which are surrounded by sealing rings 36. That in the embodiment with five
- Oil return openings 34 provided side part 32 extends over the entire length of the oil collecting housing 2, while the side part 30 provided with four oil return openings 34 in the exemplary embodiment extends from the second oil collection space 12 to the beginning of the first oil collection space 4.
- the oil return openings 34 arranged in the two side parts 30 and 32 each open into an oil collection channel 38 and 40, which are each provided with an oil drain opening 42 and 44 at their lower ends. Except for the oil return openings 34 to the crankcase (not shown), the two oil collection channels 38 and 40 are closed off by cover elements 46, which are fastened to the side parts 30, 32, for example by vibration welding.
- the holes made on the flange surface of the crankcase lower part corresponding to the oil return openings 34 sit sealingly with their bore edges on the sealing rings 36.
- the oil return channels integrated in the crankcase 5 and the oil collection channels 38 and 40 reaching up to below the oil level of the lubricating oil located in the first oil collecting space 4 ensure that the lubricating oil is quickly fed into the first oil collecting space 4 by the consumers despite the pressure pulsations caused by the crankshaft and piston movements got back.
- the lubricating oil from the main bearings of the crankshaft and the lubricating oil from the spray nozzles (not shown) for piston cooling are collected and pumped back into the first oil collecting chamber 14 via the second oil suction line 16.
- the plastic insert 15 18 fixed by the engagement of the side wall 24 in the holding groove 48 is screwed captively in the oil collecting housing 2 with the aid of fastening tabs 50 formed on the middle part 20 and on the two side parts 30 and 32.
- a sealing surface 52 is provided, via which the insert part 18 is sealed with respect to the oil guide housing 2 with its two side parts 30 and 32.
- the insert 18 is designed, in particular due to the oil holding edge 28 and the oil bulkhead 23 designed as an oil barrier, in such a way that the lubricating oil is prevented from the first oil collecting chamber 4 into the crank chamber and / or into the second even when the motor vehicle is climbing up to 45 ° Oil collecting space 12 25 can cross.
- the oil suction line 16 arranged in the second oil collecting space 12 ensures that, regardless of the incline of the vehicle, the lubricating oil from the second oil collecting space 12 passes through the oil suction line 16 and via an air separator 54 m to the first oil collecting space 4, from where it is carried out with the aid of the first Pump stage is fed back to the consumers. Since both Pump stages are constantly in operation, the air separator 54 ensures that the air drawn in from the second oil collecting space 12, particularly when driving downhill or braking the motor vehicle, is separated and thus does not reach the crankcase or the consumers.
