  • Dual-clutch transmission with integrated electric machine and utilization thereof
    Patent number: 7540823
    Abstract: New alternatives for integration of electric machines (EM1 to EM6) in an extensively integrated dual-clutch transmission (1) having one dual clutch (2), one first input shaft (8) designed as a hollow shaft and one second input shaft (9) co-axially supported in the first input shaft (8), the same as a first countershaft (10) designed as a hollow shaft and a second countershaft (11) co-axially supported. The possibilities of construction of such dual-clutch transmission are improved, and new areas of use under limiting installation space conditions are disclosed. The efficiency of the same, relative to certain possible uses, is optimized by adequate location of at least one electric machine (EM1 to EM6) and using it for a multiplicity of modes of operation are proposed.
