First Claim
Patent Images
1. A drive axle comprising:
- a first wheel end assembly defining a lateral axis of rotation;
a second wheel end assembly laterally spaced from said first wheel end assembly along said lateral axis of rotation;
a first electric motor operably coupled to drive said first wheel end assembly; and
a second electric motor operably coupled to drive said second wheel end assembly independently from said first wheel end assembly wherein said first electric motor is laterally spaced apart from said first wheel end assembly along said lateral axis of rotation by a first distance, said second electric motor is laterally spaced apart from said second wheel end assembly along said lateral axis of rotation by a second distance, and said first and second electric motors are spaced apart from each other along said lateral axis of rotation by a third distance, said first and second distances both being greater than said third distance.

Abstract
An electric drive axle includes a pair of center mounted electric motors that independently drive a pair of laterally spaced wheels. The electric drive axle includes an axle housing assembly that extends between the pair of laterally spaced wheels. Both center mounted electric motors preferably do not include connections to a chassis and are solely supported by the axle housing assembly near a vehicle centerline.
