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 housing configured to house a first product or a second product;
- and
- the first product including a first multi-stage gear train assembly that includes a first plurality of stages that includes multiple gears that rotate on a first intermediate shaft, a second intermediate shaft, and a first differential;
- and
- the second product including a second multi-stage gear train assembly including a second plurality of stages that has a fewer number of stages than the first plurality of stages, wherein the second plurality of stages include multiple gears that rotate on an intermediate shaft and a differential of the second multi-stage gear train assembly;
- wherein a center distance between a rotational axis of the first intermediate shaft and a rotational axis of the first differential of the first multi-stage gear train assembly is equivalent to a center distance between a rotational axis of the intermediate shaft and a rotational axis of the differential of the second multi-stage gear train assembly, and wherein the housing forms a portion of an electric beam axle assembly and comprises axle shaft openings.

A product line comprising:
- a housing configured to house a first product and a second product;
- the first product including a first multi-stage gear train assembly that includes a first plurality of stages that includes multiple gears that rotate on a first input shaft, first intermediate shaft, a second intermediate shaft, and a first differential;
- and
- a second product including a second multi-stage gear train assembly including a second plurality of stages that has a fewer number of stages than the first plurality of stages, wherein the second plurality of stages include multiple gears that rotate on an intermediate shaft of the second product, and a second differential;
- wherein a center distance between a rotational axis of the first intermediate shaft and a rotational axis of the first differential or the first input shaft and a center distance between a rotational axis of the intermediate shaft of the second product and a rotational axis of the second differential or second input shaft are equivalent, and wherein the housing comprises a cylindrical section that is profiled to house a motor-generator.
