Abstract:
The contribution presents a new structurally optimized 7-speed hybrid DCT for transverse applications. Advantageously the seven forward speeds can be provided with only two shafts. The space of the usually third shaft can be used for the electric motor or the mechanical reverse speed. This modular integration can be realized by using mostly identical parts for the components of the gear set and the transmission housing. The direct connection of the electric motor to the differential helps to avoid additional gear set loads and efficiency losses. Such modular transmissions will help in future to reduce development and production costs.
