Abstract
A line of vehicle transmissions is provided. The vehicle line includes a first multi-stage gear train assembly with at least two stages, a second multi-stage gear train assembly with at least three stages, and a housing including a first section removably attached to a second section. The second housing section is configured to receive the first and second multi-stage gear train assemblies in different product arrangements.
Claims20
A product line, comprising:
- a first multi-stage gear train assembly including at least two stages, two of the at least two stages comprising a pair of gears that rotate together with one another about a first intermediate shaft axis and a gear that rotates about an input shaft axis, with the first intermediate shaft axis and the input shaft axis being separated from one another by a predetermined center distance;
- a second multi-stage gear train assembly including at least three stages and a different number of stages than the first multi-stage gear train assembly, two of the at least three stages comprising a pair of gears that rotate together with one another about the first intermediate shaft axis and a gear that rotates about the input shaft axis, and a third one of the at least three stages comprising one of a pair of gears that rotate together with one another about a second intermediate shaft axis, with the first intermediate shaft axis and the input shaft axis being separated from one another by the predetermined center distance;
- and
- a housing including a first section removably attached to a second section;
- wherein the second section is configured to receive the first multi-stage gear train assembly in a first product of the product line and, instead of the first multi-stage gear train assembly, receive the second multi-stage gear train assembly in a second product of the product line.

A product line, comprising:
- a first multi-stage gear train assembly with a fixed gear ratio and including:
- one intermediate shaft with a pair of gears coupled thereto and configured to form a mesh with a gear on a first input shaft and a gear in a first differential, wherein the pair of gears rotate together with one another about a first intermediate shaft axis, the gear on the first input shaft rotates about an input shaft axis, and the first intermediate shaft axis and the input shaft axis are separated from one another by a predetermined center distance;
- a second multi-stage gear train assembly with a fixed gear ratio and including:
- a first intermediate shaft with a pair of gears coupled thereto and configured to form a mesh with a gear on a second input shaft;
- and
- a second intermediate shaft with a pair of gears coupled thereto and configured to form a mesh with a gear in a second differential, wherein the pair of gears of the first intermediate shaft rotate together with one another about the first intermediate shaft axis, the gear on the second input shaft rotates about the input shaft axis, and the first intermediate shaft axis and the input shaft axis are separated from one another by the predetermined center distance;
- and
- a housing including a first section removably attached to a second section;
- wherein the second section is configured to receive the first multi-stage gear train assembly in a first solid beam axle arrangement and the second multi-stage gear train assembly in a second solid beam axle arrangement.
