Gear box e.g. double-clutch gearbox used in drive train of hybrid vehicle, has several linked gear wheels among which one gear wheel engaged with one set of input shafts is coupled with other input shafts

摘要

The gear box (1) has input shafts (EW1,EW2) or countershafts (VW1,VW2) arranged rotatably with respect to fixed wheel (EG2,ER,VG7,VG5) and movable wheel (VG2,VR,EG5). The switching devices (SE1-SE5) are used for rotatable connection of the movable wheel with the input shafts and countershaft (VW1). The gear wheels (VG3,VG4,VG6) are arranged on countershaft (VW2) and are rotationally fixed with countershaft. The gear wheel (EG4) among linked gear wheels (EG3,EG4,EG6) engaged with input shafts (EW1,EW2) is coupled with other input shafts.
