Description

Lubrication and/or cooling system for use in a motor vehicle Technical Field The invention relates to a lubrication and/or cooling system for use in a motor vehicle, comprising a first oil container with oil and a pump assembly for transporting oil from the first oil container, wherein a first separation device is arranged in the first oil container. Background In the field of motor vehicle technology, lubrication and/or cooling systems with oil play a central role. Foam is typically formed, especially when the rotating (transmission) component is in contact with oil. In this case, the air content in the oil increases, which has a negative effect on the ability of the oil to remove heat from temperature-critical active components, for example from active components in the transmission, since a high proportion of air in the oil causes a lower specific heat capacity of the oil volume flow compared to the pure oil phase. This causes deterioration of heat transfer into the oil, so that the cooling performance of the oil is significantly reduced. Furthermore, the oil/air mixture has a lower density than the pure oil phase. Therefore, in order to achieve the same mass flow as in the case of the pure oil phase, the delivery volume flow of the delivery pump for delivering the oil must be increased. In addition, the pump has a poorer efficiency in delivering the oil-air mixture. Disclosure of Invention The object of the present invention is to propose an improved lubrication and/or cooling system for use in a motor vehicle. The need may be met by the subject matter of the present invention. Advantageous embodiments of the invention are described below. The lubricating and/or cooling system according to the invention is particularly useful in motor vehicles. However, applications in other technical fields than motor vehicle technology are not excluded. According to the invention, the lubrication and/or cooling system comprises a first oil container with oil and a pump assembly for transporting the oil from the first oil container. According to the invention, a first separating device is arranged in the first oil container, wherein the first separating device is arranged in the first oil container in an oblique manner to the flow direction of the oil, i.e. in an oblique direction towards the oil suction position of the pump assembly in an oblique manner enclosing an oblique angle with respect to the flow direction of the oil. The inclination angle is preferably less than or equal to 60 °, in particular less than or equal to 30 °, with respect to the direction of flow of the oil. The first separation device preferably has at least one screen and/or at least one filter. Furthermore, the first separation device may be arranged directly, i.e. indirectly, in the first oil container, or indirectly, i.e. indirectly, in the first oil container in the form of being mounted in a separate structural unit. In an advantageous embodiment variant, the lubrication and/or cooling system has a second oil container, wherein the second oil container is arranged at a level above the first oil container relative to the first oil container, and wherein oil can be fed from the first oil container into the second oil container via at least one mechanical component via a pump assembly. Preferably, a second separating device is arranged in the second oil container, wherein the second separating device is arranged horizontally above all oil outlets of the second oil container. The second separation device has at least one screen and/or filter and may be arranged directly, i.e. indirectly, in the second oil container or indirectly, i.e. indirectly, in the second oil container in the manner of being mounted in a separate structural unit. In particular, by means of the "tilted" or tilted at an oblique angle according to the invention arrangement of the first separating device in the first oil container, air bubbles in the oil can be displaced "upwards". The air content in the oil is thus significantly reduced, so that in particular more heat can be removed from the component cooled by the oil. Drawings The invention is described hereinafter by way of example with reference to the accompanying drawings. Fig. 1 shows a cross-section of a transmission for a motor vehicle with a lubrication and/or cooling system. Fig. 2 shows an embodiment variant of a separate structural unit with a first separating device. Detailed Description Fig. 1 schematically shows a sectional view of a transmission for a motor vehicle, wherein the lubrication and/or cooling system according to the invention is an integrated component of the transmission shown. The lubrication and/or cooling system has a first oil reservoir 1, a second oil reservoir 5 and a pump assembly 2. The second oil container 5 is disposed at a level above the first oil container 1 with respect to the spatial arrangement of the first oil container, thereby constituting a "high-level container".
