Abstract

A transmission system has a clutch module which has a single input and two outputs, where clutch devices are located between the outputs and the input. The transmission system further includes a transmission module which has two inputs and a single output, the transmission module comprising at least two sub-transmissions where at least a single speed transforming gear or a single transmission clutch is located between an input and an output of each sub-transmission. The two outputs of the clutch module are connected here to both inputs of the transmission module.

Claims (9)

1. A transmission system comprising:

a clutch module, having a single input, a first output, and a second output;

a first clutch device positioned between the first output and the input;

a second clutch device positioned between the second output and the input;

a transmission module, having a single output and a first and a second input, where between the first input and the output is located a first sub-transmission equipped with at least a single speed transforming gear and/or a single transmission clutch, and between the second input and the output is located a second sub-transmission also equipped with at least a single speed transforming gear and/or a single transmission clutch;

where the two outputs of the clutch module are connected to the two inputs of the transmission module;

a third clutch device, and between the input and the first output are located transmission means comprising at least four rotational members, a first rotational member of which is connected to the input, a second rotational member of which is connected to the first output, a third rotational member, and a fourth rotational member of which are connected to the first and the third clutch devices, respectively;

wherein the transmission system comprises a short circuit clutch which is located between the two outputs of the clutch module and/or the two inputs of the transmission module; and

wherein the transmission system comprises a further short circuit clutch which is also located between the two outputs of the clutch module and/or the two inputs of the transmission module and is connected in series with the short circuit clutch, where the two outputs of the clutch module and/or the two inputs of the transmission module can only be coupled together by closing the two short circuit clutches.
