Abstract
Official abstract text for this publication.
An axle drive ( 1 ) for a motor vehicle axle includes at least a first drive unit ( 2 ), a second drive unit ( 2 ), and an output axle ( 6 ). The first and second drive units ( 2 ) are arranged such that an overall center of gravity ( 7 ) of the axle drive ( 1 ) is situated proximate to a center of the output axle ( 6 ) and/or an axis of rotation of a vehicle wheel of the motor vehicle driven by the axle drive ( 1 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. An axle drive ( 1 ) for a motor vehicle axle, comprising: a first drive unit ( 2 ); a second drive unit ( 2 ); and an output axle ( 6 ), wherein the first and second drive units ( 2 ) are positioned such that an overall center of gravity ( 7 ) of the axle drive ( 1 ) is situated proximate a center of the output axle ( 6 ) and/or an axis of rotation of a vehicle wheel driven by the axle drive ( 1 ), and wherein each of the first and second drive units ( 2 ) comprises a respective input axle ( 5 ), and the input axles ( 5 ) of the first and second drive units ( 2 ) are arranged at the same height (z) as the output axle ( 6 ). 2. The axle drive ( 1 ) of claim 1 , wherein the first and second drive units ( 2 ) each include an electric machine ( 3 ) and a transmission ( 4 ). 3. The axle drive ( 1 ) of claim 2 , wherein each of the transmissions ( 4 ) is a countershaft transmission or is a planetary transmission. 4. The axle drive ( 1 ) of claim 1 , wherein the first and second drive units ( 2 ) each include an electric machine ( 3 ), and the first and second drive units ( 2 ) share a common transmission ( 4 ). 5. The axle drive ( 1 ) of claim 4 , wherein the common transmission ( 4 ) is a countershaft transmission or is a planetary transmission. 6. The axle drive ( 1 ) of claim 1 , wherein the first and second drive units ( 2 ) are arranged symmetrically about the center of the output axle ( 6 ). 7. The axle drive ( 1 ) of claim 1 , wherein the first and second drive units ( 2 ) are each arranged equidistant from the output axle ( 6 ). 8. An axle drive ( 1 ) for a motor vehicle axle, comprising: a first drive unit ( 2 ); a second drive unit ( 2 ); and an output axle ( 6 ), wherein the first and second drive units ( 2 ) are positioned such that an overall center of gravity ( 7 ) of the axle drive ( 1 ) is situated proximate a center of the output axle ( 6 ) and/or an axis of rotation of a vehicle wheel driven by the axle drive ( 1 ), and wherein each of the first and second drive units ( 2 ) comprises a respective input axle ( 5 ), and there is no lateral offset (y) between the input axles ( 5 ) of the first and second drive units ( 2 ).
