Abstract
A double clutch transmission of a vehicle having an internal combustion engine and a clutch chamber (3) which is designed as a first oil chamber, for accommodating a double clutch, and a transmission chamber (8) which is designed as a second oil chamber, for accommodating a double clutch transmission gear set. A partition wall (9) separates the oil chambers from one another. An oil pump (11) is positioned in the transmission chamber (8) and can be driven by a drive shaft (7) which extends through the partition wall (9) from the transmission chamber (8) into the clutch chamber (3).

A double clutch transmission, for a motor vehicle with an internal combustion engine, comprising:
- a clutch chamber (3), comprising a first oil chamber accommodating a double clutch therein,
- a transmission chamber (8), comprising a second oil chamber accommodating a double clutch transmission gear set therein,
- a partition wall (9) separating the first and the second oil chambers from one another, and
- a first pump, comprising an oil pump (11), being positioned in the transmission chamber (8) and being driven by a drive shaft (7), and the drive shaft (7) extending through the partition wall (9) into the clutch chamber (3), and a second pump, which comprises a hydraulic pump that is drivable by the internal combustion engine, is positioned in the clutch chamber (3).
A double clutch transmission of a motor vehicle having an internal combustion engine, the double clutch transmission comprising:
- first and second oil chambers,
- the first oil chamber accommodating a double clutch and a second oil pump and the second oil chamber accommodating a double clutch transmission gear set,
- the first and the second oil chambers being separated from one another by a partition wall,
- a first oil pump being located within the second oil chamber and being fixed to the partition wall, and the oil pump comprising a pump shaft,
- the partition wall comprising a bore through which a drive shaft extends, a first end of the drive shaft engaging with and being driven by a spur gear located within the first oil chamber and a second end of the drive shaft being continuously connected, via a connector, to the pump shaft such that drive shaft and the pump shaft rotate together,
- the spur gear, located in the first oil chamber, communicating with a further spur gear that is driven by the internal combustion engine such that the pump shaft is driven by the internal combustion engine, and
- a seal member being located within the bore and engaging with the drive shaft for sealing the first oil chamber with respect to the second oil chamber.
