Embodiments of a cold start lubricant distribution system include a lubricant distribution circuit, which fluidly interconnects first and second actively-lubricated work vehicle assemblies onboard a work vehicle. A flow divider section is included in the lubricant distribution circuit and through which lubricant flow is apportioned between the first and second actively-lubricated work vehicle assemblies. A lubricant supply pump is further located in the lubricant distribution circuit upstream of the flow divider section. The cold start lubricant distribution system further includes a lubricant flow modification assembly operably in a cold start mode. When operating in the cold start mode, the lubricant flow modification assembly reduces a volume of lubricant flow supplied to the first actively-lubricated work vehicle assembly through the flow divider section relative to a volume of lubricant flow supplied to the second actively-lubricated work vehicle assembly through the flow divider section.

A cooling system includes: (a) a first pump to be driven with vehicle running; (b) a lubricating passage for supplying the lubricant from the first pump, to a lubrication-required part; (c) a second pump to be driven by a drive source other than a drive source of the first pump; (d) a cooling passage for supplying the lubricant from the second pump, to a rotary electric machine via a heat exchanger provided in the cooling passage; (e) a connecting passage connecting between the lubricating passage and the cooling passage, and (f) a lubricant distribution portion configured to change a connecting-passage flowing amount of the lubricant that flows through the connecting passage, depending on a temperature of the lubricant, such that a ratio of the connecting-passage flowing amount to a lubricating-passage flowing amount of the lubricant that flows through the lubricating passage is increased with increase of the lubricant temperature.

The invention relates to an oil sump (1) comprising a lower shell (2) intended for containing lubricating oil of an engine, in which a flow of oil, referred to as suction oil flow (I), is sucked up via a suction tube (44) to supply a lubricating circuit, and an oil flow, referred to as returning oil flow (II), falls into the oil sump (1). The oil sump (1) comprises an anti-emulsion plate (8) arranged located at the mouth of the suction tube (44) during a transitional period in which the temperature of the oil is lower than an optimal operating temperature.
