Method and apparatus for lubricating a transmission of a motor vehicle

摘要

The invention relates to a method for lubricating a transmission of a motor vehicle, particularly a power divider, wherein the oil is conveyed by an oil pump from an oil sump to components of the transmission. The amount of oil conveyed is set as a function of the predetermined parameters. The conveyed amount of oil is controlled in that the oil pump is operated intermittently, e.g. is switched on and off repeatedly. The invention further describes a device for carrying out the method.

主权项

1. A system for lubricating a transmission of a motor vehicle, comprising:
a plurality of transmission components; an oil pump conveying an amount of lubricating oil to said transmission components; a drive unit receiving an input voltage and using the input voltage to drive said oil pump, wherein the input voltage is received by said drive unit during preset durations of time and no voltage is received by said drive unit during intervals between the preset durations of time, and wherein a first group of the preset durations of time during which the input voltage is received by the drive unit are equal to one another, a second group of the preset durations of time following the first group are equal to one another, and the preset durations of time of the first group are different from the preset durations of time of the second group, the input voltage received by said drive unit during each preset duration of time is greater than a minimum voltage required to start said drive unit and said oil pump, and the amount of lubricating oil conveyed by said oil pump to said transmission components is proportional to the input voltage received by said drive unit.
