Abstract

The invention relates to a hybrid module including a clutch that includes a clutch actuator, also including an electric machine, an internal combustion engine end and a transmission end. The hybrid module is designed as a pre-assembled insertable module to be inserted into a transmission housing, and an actuator electronics module is already pre-mounted on the hybrid module. The invention further relates to a method for assembling a hybrid module, characterized in that the following step is carried out:—pre-assembling the hybrid module as an insertable module, an actuator electronics module being pre-mounted on the hybrid module.

Claims

1. A hybrid module having an engine side facing an internal combustion engine and a transmission side, the hybrid module comprising:

a clutch with a clutch actuator, an electric machine, and an actuator electronics module which are preassembled to form the hybrid module, the actuator electronics module is preassembled with a holder with the hybrid module such that it is radially distanced from a center of the hybrid module at a distance which is sized such that in an installed state the hybrid module is adapted to be arranged inside the transmission housing and the actuator electronics module is arranged outside the transmission housing.

2. The hybrid module according to claim 1, wherein the actuator electronics module is fastened at wall of the module adapted to extend radially at a side of the internal combustion engine.

3. The hybrid module according to claim 1, wherein the actuator electronics module is fastened via the holder, which comprises at least one brace with a radially extending section, to the hybrid module, with the brace being fastened at one end section thereof to the hybrid module and with another end section thereof connected to the actuator electronics module.

4. The hybrid module according to claim 3, wherein the other end section or the section of the holder adjoining thereto or the actuator electronics module comprises a fastening option for fastening to the transmission housing.

5. The hybrid module according to claim 3, wherein the brace comprises at the one end section an axially extending section which merges into the radially extending section.

6. The hybrid module according to claim 3, wherein the holder comprises radially outside an exterior perimeter of the hybrid module an axially extending section merging with the radially extending section.

7. The hybrid module according to claim 3, wherein the brace comprises a grommet.

8. The hybrid module according to claim 3, wherein at least one cable is laid along the brace from the hybrid module to the actuator electronics module.

9. The hybrid module according to claim 3, wherein at least one plug-in connection component is fastened at the other end section or at a section of the holder abutting thereto or at the actuator electronics module.

12. A drivetrain comprising a hybrid module according to claim 1, a transmission housing, the hybrid module is arranged in a dry housing part of the transmission housing, at least a portion of the transmission housing axially encompasses at least a portion the hybrid module, and the actuator electronics module connected to the hybrid module is radially distanced from the hybrid module so that at least a section of the transmission housing is located between the actuator electronics module and the hybrid module.

10. A method for the assembly of a hybrid module comprising the following steps:

preassembling the hybrid module as an insertable module, with an actuator electronics module preassembled with the hybrid module,

inserting the hybrid module into a transmission housing, with the hybrid module, the transmission housing, and the actuator electronics module sectionally overlapping at least one of axially or radially, and at least sections of the transmission housing being located radially between the hybrid module and the actuator electronics module.

11. The method according to claim 10, further comprising before and after the preassembly performing at least a calibration or a functional test of the actuator electronics module together with the hybrid module.
