A transmission system is disclosed, having a clutch module with an input and a first and a second output. Between the first output and the input, a first clutch device is present, and between the second output and the input a second clutch device is present. The transmission system further includes a transmission module having a first partial transmission and a second partial transmission, in which the two outputs of the clutch module are connected to the two inputs of the transmission module.

Transmission system

A drive mechanism comprises a transmission as well as an electromotor/generator. The transmission is connected via an input to the electromotor/generator and via an output to the wheels. The transmission has two planetary gear sets having three rotational members each, of which first rotational members are connected to the input, second rotational members are connected to the output and third rotational members are connected to a first and second brake respectively. By actuating either of the brakes a speed transforming gear is created between the input and the output. By actuating one brake during the releasing of the other brake, it is possible to switch between the two speed transforming gears without an interruption of the torque transfer from the electromotor/generator to the load or vice versa.

An exemplary transmission system (TS) includes a clutch module (CM) having an input (In) and a first and a second output (O, O). A first clutch device (B, B, C) provided with a first actuator is present between the first output and the input, and a second clutch device (C, B) with a second actuator is present between the second output and the input. The transmission system also includes a transmission module (TM), with an output (Out) and a first and a second input (i, i). A first partial transmission provided with at least one transmission (VAR) is present between the first input and the output, and a second partial transmission provided with at least one further transmission or a mechanical connection is present between the second input and the output. Two outputs (O, O) of the clutch module are connected to the two inputs (i, i) of the transmission module.

A clutch and/or brake module has a heat sink which is attached to a transmission housing for the purpose of discharging heat. The brake module further has a brake disc, which is connected to a rotational member formed by a shaft (schematically indicated by a center line). The brake disc is provided on one side with a lining and faces with this side towards the heat sink. The brake is a dry brake and is not lubricated. The brake module further has an actuation system (cylinder with piston movable therein, schematically indicated by an arrow) which can exert an axial pressing force directly on the brake disc. The brake disc is located axially between the heat sink and the actuation system. The cooling plate is secured to a transmission housing, a part of which is schematically shown.

A transmission which is pre-eminently suitable for an electric and/or hybrid drive has an input which can be connected to an electromotor/generator, and an output which can be connected to a load. The transmission has two parallel transmission paths between the input and output, first coupling means being present in the first transmission path and second coupling means being present in the second transmission path. Furthermore, a gear reduction is present in at least either of the two transmission paths. The first coupling means are arranged such that they are not capable of dissipating significant power and the second coupling means are arranged such that they are capable indeed of dissipating significant power.

Transmission for an electric or hybrid drive

A flywheel module has a closed housing with an opening, and an output which is formed by an output shaft that extends outward through the opening. A sealing ring is present between the output shaft and the boundary wall of the opening. A flywheel is accommodated in the housing, which flywheel is connected via a clutch to a first gear of a transmission whose other gear is connected to a first portion of a centrifugal disengaging clutch of which the other portion is connected to the output shaft. With this it be avoided that the flywheel starts to run at too high a speed, which guarantees the safety of the flywheel module.
