Abstract

A drivetrain package includes a motor which includes a rotor shaft, a gear unit, and a carrier structure. The carrier structure has a carrier part which includes a gear unit support section and a motor support part, the carrier part and the gear unit support section being arranged in one piece. The motor is mounted on the carrier structure with the aid of the motor support part, the motor support part in particular being situated between the motor and the carrier part. The gear unit is supported on the gear unit support section and connected to the carrier structure with the aid of the gear unit support section. The carrier part includes a sheet metal part, and the motor support part includes a sheet metal part. The carrier part extends farther in the direction of the rotor shaft axis than in a transverse direction to the direction of the rotor shaft axis, and the motor support part extends farther in a transverse direction to the direction of the rotor shaft axis than in the direction of the rotor shaft axis.

First claim

The invention claimed is:

1. A drivetrain package, comprising:
a motor having a rotor shaft;
a gear unit; and
a carrier structure having a carrier part including a gear unit support section and a motor support part, the carrier part and the gear unit support section being arranged in one piece;
wherein the motor is mounted on the carrier structure by the motor support part, the motor support part being arranged between the motor and the carrier part;
wherein the gear unit is supported on the gear unit support section and connected to the carrier structure by the gear unit support section;
wherein the carrier part and the motor support part include sheet metal parts;
wherein the carrier part extends farther in a direction of a rotor shaft axis than in a transverse direction to the direction of the rotor shaft axis; and
wherein the motor support part extends farther in a transverse direction to the direction of the rotor shaft axis than in the direction of the rotor shaft axis.

2. The drivetrain package according to claim 1 , wherein the carrier structure includes a base part, and the carrier structure is supported by the base part on a foundation and/or on a floor, the motor support part and the base part having a similar and/or identical configuration, the base part extending farther in a transverse direction to the direction of the rotor shaft axis than in the direction of the rotor shaft axis.

3. The drivetrain package according to claim 1 , wherein the motor support part and the base part each have a first recess and a second recess, the motor adapted to be connected to the carrier structure by a fastening element that is guided through the first recess, the first recess including as an elongated hole that extends farther in the direction of the rotor shaft axis than in a transverse direction to the direction of the rotor shaft axis, the carrier structure adapted to be mounted on a foundation and/or on a floor by a fastening element that is guided through the second recess.

4. The drivetrain package according to claim 2 , wherein the carrier part, the motor support part, and/or the base part includes a bent part, a punched and bent part, and/or an angled sheet metal part.

5. The drivetrain package according to claim 1 , wherein the carrier part includes two subsections that are disposed at a non-vanishing angle with respect to each other, the angle being between 90° and 180°, between 135° and 180°, and/or between 150° and 170°, an edge section, which extends completely through the carrier part in the direction of the rotor shaft axis, being situated between the subsections.

6. The drivetrain package according to claim 2 , wherein the motor support part and/or the base part is connected to the carrier part by form-locking, by an intermaterial connection, and/or by welding, the carrier part including at least one positioning slot for connection to the motor support part or to the base part.

7. The drivetrain package according to claim 1 , wherein the carrier part includes a carrier section that extends from the motor to the gear unit, the gear unit support section arranged at a non-vanishing angle to the carrier section, the gear unit support section arranged at a right angle to the carrier section, the gear support section extending farther in the direction of the rotor shaft axis than in a transverse direction to the direction of the rotor shaft axis.

8. The drivetrain package according to claim 1 , wherein the carrier part includes a bottom section arranged at a non-vanishing angle to the carrier section, the angle between the bottom section and the carrier section being greater than or equal to 90°, between 90° and 180°, between 90° and 135°, and/or between 100° and 120°, the bottom section being disposed between two carrier sections having a substantially U-shaped cross-section.

9. The drivetrain package according to claim 1 , wherein a torque support is connected to the carrier structure by a torque support plate, the torque support plate connected to the carrier part by form-locking, by studs, and/or in a form-locking and an intermaterial manner, the torque support connected to the torque support plate in a detachable manner and/or by a screw connection.

10. The drivetrain package according to claim 1 , wherein the carrier structure includes a sheet metal part, including a bent part, at least partially situated between two gear unit support sections.

11. The drivetrain package according to claim 1 , wherein the carrier part includes two parts, two halves of the carrier part being intermaterially connected and/or welded to each other, the carrier part having a linear weld seam and/or a square butt weld that extends in the direction of the rotor shaft axis, the weld seam being interrupted by at least one recess and/or a recess that extends farther in the direction of the rotor shaft axis than in a transverse direction to the direction of the rotor shaft axis, the two halves of the carrier part being arranged in mirror symmetry with respect to each other.

12. The drivetrain package according to claim 1 , further comprising a clutch and/or a hydraulic clutch connecting the rotor shaft of the motor and an input shaft of the gear unit to each other, the carrier structure including a trough that overlaps a region covered by the clutch in the direction of the rotor shaft axis, the trough being intermaterially connected to and/or welded to the carrier part.

13. The drivetrain package according to claim 1 , further comprising a fan arranged between a clutch and the gear unit in the direction of the rotor shaft axis, a fan wheel of the fan being connected to an input shaft of the gear unit in a torsionally fixed manner.

14. The drivetrain package according to claim 1 , wherein the carrier structure includes recesses and/or recesses arranged as transport bores, the recesses including as punched and/or cut recesses.

15. The drivetrain package according to claim 14 , wherein the recesses are arranged as transport eyelets and/or for accommodation of forks of a fork lift.
