Abstract
The invention relates to a tandem pump (1) for an electric axle of a motor vehicle, comprising a dry sump flow (2) via which hydraulic fluid can be delivered from a transmission chamber into a hydraulic chamber, and a main flow (3) via which hydraulic fluid can be delivered from the hydraulic chamber to a hydraulic consumer, wherein the dry sump flow (2) and the main flow (3) are formed by types of pumps having different inflow directions.
Claims20
A tandem pump for an electric axle of a motor vehicle, comprising a dry sump flow via which hydraulic fluid can be conveyed from a transmission chamber into a hydraulic chamber, and a main flow via which hydraulic fluid can be conveyed from the hydraulic chamber to a hydraulic consumer, wherein the dry sump flow and the main flow are formed by pumps having different inflow directions.
A tandem pump for an electric axle of a motor vehicle comprising:
- a dry sump flow configured to convey hydraulic fluid from a transmission chamber into a hydraulic chamber;
- a main flow configured to convey hydraulic fluid from the hydraulic chamber to a hydraulic consumer;
- wherein the dry sump flow is mechanically coupled to the main flow;
- and
- wherein the dry sump flow and the main flow are formed by a plurality of pumps having different inflow directions.
A motor vehicle comprising:
- an electric axle, wherein the electric axle includes a tandem pump configured to supply one or more hydraulic consumers with hydraulic fluid, wherein the tandem pump comprises:
- a dry sump flow configured to convey hydraulic fluid from a transmission chamber into a hydraulic chamber;
- a main flow configured to convey hydraulic fluid from the hydraulic chamber to the one or more hydraulic consumers;
- wherein the dry sump flow is mechanically coupled to the main flow;
- and
- wherein the dry sump flow and the main flow are formed by a plurality of-pumps having different inflow directions.
