Abstract:
1. An arrangement for warming oil in a gearbox of a combustion engine which is lubricated and cooled by a motor oil, the arrangement comprising: a first pipe system, a first flow device operable for circulating motor oil from the combustion engine through the first pipe system; a second pipe system separate from the first pipe system, a second flow device operable for circulating oil from the gearbox through the second pipe system; a heat exchanger connected to the first pipe system and to the second pipe system and configured for causing a heat exchange in the heat exchanger between the oils in the first and the second pipe systems, and a control device operative to control the first and second flow devices so that the oils are circulated through their respective pipe systems and are selectively circulated through the heat exchanger in at least certain situations in which the oil in the gearbox is at a temperature below a desired temperature.
