Problems solved by technology

Such systems therefore often have a complex and / or space-consuming construction, mutually separated oil volumes and / or at least partially duplicative components
Thus, systems with a lubricating oil circuit and a cooling oil circuit are known in the prior art, such as a vehicle transmission with a single-speed transmission or a multi-speed transmission lubricated by the lubricating oil circuit and with an electric machine cooled by the cooling oil circuit. systems, often complex, space-consuming, expensive and / or very heavy

Embodiment Construction

[0046] figure 1 Shown is an embodiment of a system 100 according to the invention, for example a vehicle drive train, comprising a transmission 20 with bearings lubricated by a lubricating oil circuit S, in particular a transmission bearing 21, and a rotor with cooling by a cooling oil circuit K 31 of the motor 30 and an embodiment of the oil reservoir 10 according to the invention, and figure 1 The principle of the distribution of oil according to the invention into the lubricating oil circuit S and the cooling oil circuit K and the principle of the oil delivery according to the invention are shown.

[0047] figure 1 It is shown that the oil reservoir 10 is designed to distribute the oil 1 into the lubricating oil circuit S and the cooling oil circuit K. In this case, the oil reservoir 10 preferentially supplies the lubricating oil circuit S with oil 1 . To this end, the oil reservoir 10 has a first oil reservoir 11 for supplying oil to the lubricating oil circuit S and a ...

Abstract

The invention relates to an oil reservoir (10) for a system (100) having a lubricating oil circuit (S) and a cooling oil circuit (K), a system (100) equipped with the oil reservoir, such as a vehicle drive train having a lubricating oil circuit (S) and a cooling oil circuit (K), and a method for operating the system. The system (100) can thus be constructed more simply, more space-saving, cheaper and / or more cost-effective, or correspondingly achieved in that the system (100) comprises an oil reservoir (10) which is designed to distribute the oil (1) into the lubricating oil circuit (S) and the cooling oil circuit (K).

Description

technical field [0001] The invention relates to an oil reservoir for a system having a lubricating oil circuit and a cooling oil circuit, in particular for a drive train of a vehicle having a transmission and / or a bearing lubricated by lubricating oil circuit oil , and motors cooled by oil in the cooling oil circuit. The invention also relates to a system with a lubricating oil circuit and a cooling oil circuit, in particular a vehicle drive train having a transmission and / or bearings lubricated by lubricating oil circuit oil and an electric machine cooled by cooling oil circuit oil . The invention also relates to a method for operating such a system. Background technique [0002] Single and multi-speed transmissions are usually lubricated by splash lubrication. The rotating parts of this transmission are immersed in oil and distribute it within the transmission housing. Oil can be supplied to the various lubrication points in a targeted manner by using oil guides and oi...
