The chain includes an arrangement having a dog clutch (46) with a neutral position between gear ratios. The dog clutch provides direct engagement between an input shaft and one of two gearwheels, and has a mechanical transmission path between the input shaft and the other gearwheel with a reduction ratio different from the direct engagement. The two gearwheels are permanently meshed with a rotating toothed wheel (3). The input shaft is coupled with the shaft of an electric motor (M). An Independent claim is also included for a process for controlling gear ratio changes. |
