Dual gerotor apparatus, a powertrain assembley and an electrified vehicle

A dual gerotor apparatus, comprising:

• a housing configured to provide a first and second hydraulic fluid circuit sharing a same single fluid inlet and a same single fluid outlet;
• a gerotor assembly coupling with a rotatable shaft, the gerotor assembly includes a first gerotor pump and a second gerotor pump;
• and
• a separation element disposed between the first gerotor pump and the second gerotor pump in an axial direction,
• wherein the gerotor assembly is configured to transfer a hydraulic fluid flowing through the first or second hydraulic fluid circuit from the single fluid inlet to the single fluid outlet, and
• wherein the first gerotor pump is configured to be in operation when the rotatable shaft rotates in a first direction, and the second gerotor pump is configured to be in operation when the rotatable shaft rotates in a second direction,
• wherein the separation element is configured for isolating the fluid communication between the first and second gerotor pumps and for forming the first hydraulic fluid circuit,
• wherein the separation element comprises an outer circumferential wall axially extending from a body portion of the separation element and along an outer periphery the first gerotor pump, the outer circumferential wall is configured for limiting a radial displacement for the first gerotor pump and for directing the first hydraulic fluid flowing through the first hydraulic fluid circuit, and
• wherein a portion of the first hydraulic circuit is positioned between an outer surface of the outer circumferential wall and an inner circumferential surface of the housing.
