Embodiment Construction

[0035] figure 1 The transmission assembly 1 for a vehicle 2 is shown in a schematic illustration, however, the vehicle 2 is only shown schematically as a box. The transmission assembly 1 forms part of the drive train of a vehicle 2 .

[0036] The transmission assembly 1 has an input connection 3 , which is coupled in a rotationally fixed manner to an electric motor 4 . Electric motor 4 is designed as a traction motor for vehicle 2 and, on the one hand, can form the only traction motor for vehicle 2 . Alternatively, vehicle 2 can be designed as a hybrid vehicle which has a further motor besides electric motor 4 as traction motor for the drive. It is also possible for the vehicle 2 as an electric vehicle to have one or more further electric motors as traction motors.

[0037] Furthermore, the transmission assembly 1 has an output connection 5 which is coupled in a rotationally fixed manner to a differential gear arrangement 6 . The differential device 6 is used to selectivel...

Abstract

The invention addresses the problem of proposing a gearing arrangement for an electric motor which is improved in terms of ease of use and efficiency. To this end there is proposed a gearing arrangement (1) for an electric motor (4) of a vehicle (2), comprising an input interface (3) for coupling to the electric motor (4) and comprising an output interface (5), such that a drive torque path runs between the input interface (3) and the output interface (5); comprising a first transmission gearing stage (7) with a first transmission ratio (i1), such that the drive torque path in a first gearshift state runs via the first transmission gearing stage (7); and comprising a second transmission gearing stage (8) with a second transmission ratio (i2), such that the drive torque path in a second gearshift state runs via the second transmission gearing stage (8); and comprising an intermediate transmission gearing stage (9) with a continuously variable transmission ratio (i1..i2), such that the drive torque path in an intermediate gearshift state runs via the intermediate transmission gearing stage (9).

Description

technical field [0001] The invention relates to a transmission assembly for an electric motor of a vehicle, having an input connection for coupling to the electric motor and to an output connection, wherein a torque path extends between the input connection and the output connection, said transmission assembly having a first A first transmission section of a transmission ratio, wherein the torque path runs on the first transmission section in a first shifting state, and the transmission assembly has a second transmission with a second transmission ratio A transmission section, wherein the torque path runs over the second transmission section in the second shifting state. Background technique [0002] Today, electric vehicles typically only operate in one gear stage. However, it is thus not possible to operate the electric motor operating as traction motor in a range that is optimal for the respective speed. The use of a two-speed transmission for the electric motor appears...
