Transmission module for a hybrid drive
A drive mechanism has a transmission module which has a first input which is connected to an electromotor/generator, and a second input which is connected to a combustion engine. The transmission module has a planetary gear set having three rotational members of which a first rotational member is connected to the input, a second rotational member is connected to an output, and a third rotational member is connected to a brake. A clutch is positioned between the combustion engine and the third rotational member and a further clutch is positioned between the combustion engine and the first rotational member.
1. A transmission module for a hybrid drive mechanism having a first input which can be connected to an electromotor/generator, and an output which can be connected to a load, the transmission module comprising:
a brake;
an epicyclic gearing comprising at least three rotational members, a first rotational member adapted to be connected to the first input, a second rotational member adapted to be connected to the output, and a third rotational member being connected to the brake;
a second input adapted to be connected to a combustion engine and which is or can be connected to the third rotational member;
a clutch which is positioned between the second input and the third rotational member; and
a further clutch which is positioned between the second input and the first rotational member.
2. The transmission module of claim 1 , further comprising a short-circuit clutch which is positioned between two of the three rotational members.
3. The transmission module of claim 1 , further comprising a fixed and/or variable speed transforming gear and/or a switchable transmission which is positioned between one of the rotational members and the first or second input, brake or output connected to that member.
4. A drive mechanism for a vehicle having wheels, the drive mechanism comprising:
an electromotor/generator;
a combustion engine;
a hybrid drive mechanism having a first input which is connected to the electromotor/generator, and an output which is connected to the wheels of the vehicle; and
a transmission module comprising:
a brake;
an epicyclic gearing comprising at least three rotational members, a first rotational member connected to the first input, a second rotational member connected to the output, and a third rotational member being connected to the brake;
a second input adapted to be connected to a combustion engine and which is or can be connected to the third rotational member;
a clutch which is positioned between the second input and the third rotational member; and
a further clutch which is positioned between the second input and the first rotational member.
5. A transmission module used in conjunction with an electromotor/generator and a load, the transmission module comprising:
a hybrid drive mechanism having a first input which can be connected to the electromotor/generator, and an output which can be connected to the load;
a brake;
an epicyclic gearing comprising at least three rotational members, a first rotational member adapted to be connected to the first input, a second rotational member adapted to be connected to the output, and a third rotational member being connected to the brake;
a second input adapted to be connected to a combustion engine and which is or can be connected to the third rotational member;
a clutch which is positioned between the second input and the third rotational member; and
a further clutch which is positioned between the second input and the first rotational member.
