Abstract
An electrical drive system for a vehicle with a skid steering element exhibits a homogeneous electrical drive engine and a homogeneous gear unit (16, 18) on the left and on the right side in each case, which are propelled by a drive engine (2,4), assigned in each case, and over a power drive flange (28, 40) to propel a track or a drive wheel. Two transfer elements (26, 24) of the left gear unit (16), which do not form the drive, are directly connected by a mechanical gear train crosswise in each case with both transfer elements (36, 38) of the right gear unit, which do not form the drive.
Claims4
An electrical drive system for a vehicle with a skid steering element having at least:
- a left electrical drive engine (2) and a homogeneous right electrical drive engine (4);
- an electrical energy source (6);
- an electrical control unit (8) for independently increasing a number of revolutions at the left electrical drive engine (2) and the right electrical drive engine (4);
- a left gear unit (16), connected with one of a left drive wheel or track of a left drive unit (22, 28), and the left drive engine (2) is connected with a first left transfer element (26) and a second left transfer element (24);
- a homogeneous right gear unit (18) connected with one of a right drive wheel or track of a right drive unit (34, 40), and the right drive engine (4) is connected with a first right transfer element (38) and a second right transfer element (36);
- and
- a first left transfer element (26) is connected directly with the second right transfer element (36) by a first mechanical gear train (44, 50;
- 48, 52;
- 46), and the first right transfer element (38) is connected directly with the second left transfer element (24) by a second mechanical gear train (54, 60;
- 58, 62;
- 56).
