Abstract:
1. A transmission for an electric or hybrid drive, which has an input which can be connected to an electromotor/generator or combustion engine that forms a main drive, and an output which can be connected to a load, which transmission comprises: two parallel transmission paths between the input and output, wherein the two parallel transmission paths are distinct paths without any overlapping components, which each extend from the input of the electromotor/generator or combustion engine, to the output of the load; first coupling means being present in a first one of the two transmission paths and second coupling means being present in the other, second transmission path, and a gear reduction having a gear ratio unequal to 1 being present in at least either of the two transmission paths, the maximum amount of power the first coupling means can dissipate is less than the maximum amount of power the second coupling means can dissipate, wherein each of the coupling means can be a clutch comprising two parts which can be connected together, or a brake or electromotor/generator in combination with a planetary gear set having at least three rotating members, wherein in case the coupling means is a clutch, the first part is uninterruptedly connected to the input, and the second part is uninterruptedly connected to the output directly or via the gear reduction or, in case the coupling means is a brake or an electromotor/generator, this brake or electromotor/generator is connected to a third rotational member of the planetary gear set of which a first rotational member is uninterruptedly connected to the input and yet a second rotational member is uninterruptedly connected to the output directly or via the gear reduction.
