Abstract
A torque transmission arrangement, particularly for an arrangement with an electric machine in a drive module of a hybrid vehicle or electric vehicle, for transmitting a torque from an output shaft, particularly a motor output shaft, to a drive shaft, particularly a transmission input shaft. The drive shaft further has at least one fluid guide channel in which a fluid can be guided in direction of the output shaft. A fluid-carrying element which guides fluid out of the fluid guide channel of the drive shaft into a radially outer region of the output shaft and is provided at the output shaft.
Claims16
A torque transmission arrangement for an arrangement with an electric machine in a drive module of a hybrid vehicle or electric vehicle, configured to transmit torque from an output shaft to a drive shaft, comprising:
- at least one fluid guide channel arranged in the drive shaft and configured to guide a fluid towards the output shaft;
- a fluid-carrying element that guides the fluid out of the at least one fluid guide channel of the drive shaft into a radially outer region of the output shaft at the output shaft,
- wherein the output shaft is a hollow shaft and a fluid-receiving interior of the output shaft is configured to receive and/or guide the fluid, and
- at least one further shaft that surrounds the drive shaft and configured as a rotor hub, which is formed as a hollow shaft, wherein the at least one further shaft extends into the output shaft constructed as hollow shaft such that the fluid-receiving interior of the output shaft is formed as annular space between output shaft and further shaft,
- wherein the interior of the at least one further shaft is in fluidic connection with the at least one fluid guide channel of the drive shaft and the fluid-receiving interior of the output shaft.
A drive module comprising:
- an electric machine;
- and
- a torque transmission arrangement configured to conduct a torque from an output shaft of an internal combustion engine and/or electric machine to a drive shaft of a transmission comprising:
- at least one fluid guide channel arranged in the drive shaft and configured to guide a fluid towards the output shaft;
- a fluid-carrying element that guides the fluid out of the at least one fluid guide channel of the drive shaft into a radially outer region of the output shaft at the output shaft,
- wherein the output shaft is a hollow shaft and a fluid-receiving interior of the output shaft is configured to receive and/or guide the fluid, and
- at least one further shaft that surrounds the drive shaft and configured as a rotor hub, which is formed as a hollow shaft, wherein the at least one further shaft extends into the output shaft constructed as hollow shaft such that the fluid-receiving interior of the output shaft is formed as annular space between output shaft and further shaft,
- wherein the interior of the at least one further shaft is in fluidic connection with the at least one fluid guide channel of the drive shaft and the fluid-receiving interior of the output shaft.
