Light commercial vehicles, currently mostly driven by Diesel engines, typically cover very diverse route profiles and use cases. In the future, solutions are needed that allow emission‐free driving in the city. However, exclusively running BEVs is no option for many businesses, because interurban longer‐distance capability is required as well. That favors a hybrid drive, which can be electrified in different scales to specific needs, to enable lowest possible total cost of ownership (TCO).Continue reading

The new type of DCT, which is named “DT1”, is not of the typical design layout that is typically seen in existing DCT products. The new dual clutch uses two different wet friction subsystems configured in axial arrangement. One of them is actually a wet clutch whereas the second one is a planetary gearset controlled by a wet brake. This enables a reduced number of gearsets, a single layshaft and an extraordinary thermal stability of this 200Nm 7speed DCT.Continue reading

The multi mode e-transmission developed by GKN has been in production at Shanghai GKN Huayu driveline system Co. Ltd. This e-transmission has an unique architecture which can support different driving modes such as pure EV, serial hybrid and parallel hybrid. By supporting different driving modes it can help a HEV or PHEV car to fulfill best fuel-efficiency while ensure its dynamic performance characteristics.Continue reading

The vehicle segment up to 300 Nm has the largest share within the global market. It is particularly price-sensitive and requires strong economy of scale. However, increasing hybridization multiplies the number of functional variants. They range from 48V hybrid drives to HV and HV plug-in hybrid drives. In addition, on high electrification levels with a dominant e-machine, it becomes desirable to reduce mechanical complexity.Continue reading
