Abstract
A differential gear is provided in which the differential includes a drive gear, at least two axle gears, at least two compensating gears and a single-piece connecting element. The drive gear at least partially encloses an interior space in which the connecting element is arranged, thereby providing a compact, strong differential without use of a differential cage.
Claims10
A differential, comprising:
- at least one drive gear;
- at least two axle gears;
- at least two compensating gears;
- and
- at least one connecting element,
- wherein
- the drive gear is a gearwheel that at least partially encloses an interior space,
- the connecting element is constructed as a single piece and arranged at least partially inside the interior space,
- the connecting element has at least six pins that extend outward from a central region of the connecting element, wherein
- at least two of the at least six pins are axle gear pins configured to receive a corresponding one of the at least two axle gears rotatably mounted thereon, the at least two axle gear pins being arranged on a first axis of the connecting element,
- at least two of the at least six pins are compensating gear pins configured to receive a corresponding one of the at least two compensating gears rotatably mounted thereon, the at least two compensating gear pins being arranged on a second axis of the connecting element and being connected to an inner surface of the drive gear,
- the second axis is in essence perpendicular to the first axis, and
- at least two of the at least six pins are fastening pins connected to the inner surface of the drive gear.
