Abstract

A device (1) for cooling and lubricating components of a vehicle (2) may include a housing (3), a coolant sump (4), a coolant pump (5) for pumping coolant (6) from the coolant sump (4), a heat exchanger (7) for cooling coolant (6) from the coolant pump (5), and a coolant line system (8) including a coolant reservoir (9) having a single coolant inlet (10) and multiple coolant outlets (11.1, 11.2, 11.3, 11.4, 11.5). The coolant line system (8) fluidically connects the coolant pump (5) to the heat exchanger (7), and the heat exchanger (7) to the single coolant inlet (10) of the coolant reservoir (9). The coolant reservoir (9) receives coolant (6) from the heat exchanger (7) via the single coolant inlet (10) and directs coolant (6) via the multiple coolant outlets (11.1, 11.2, 11.3, 11.4, 11.5) onto components in the housing (3) requiring cooling and lubrication.
