STATOR HOUSING AND BEARING SUPPORT CONNECTION
First Claim
1. A transmission having an electric motor/generator, the transmission comprising:
- a transmission housing;
a bearing support rigidly connected to the transmission housing and substantially enclosed by the transmission housing;
a plurality of rivets; and
a stator housing substantially enclosed by the transmission housing, wherein the stator housing is rigidly joined to the bearing support by the plurality of rivets, such that torque may be transferred between the stator housing and bearing support.

Abstract
A transmission having an electric motor/generator includes a transmission housing and a bearing support rigidly connected to the transmission housing and substantially enclosed by the transmission housing. A stator housing is substantially enclosed by the transmission housing, and is rigidly joined to the bearing support by a plurality of rivets, such that torque may be transferred between the stator housing and bearing support. The stator housing may be formed from a first material, and the bearing support may be formed from a second material, different from the first material. The stator housing and bearing support meet at an interface region, which may be characterized by an absence of a welded connection between the stator housing and the bearing support. The interface region may be characterized as a slip fit, such that the stator housing and bearing support are matable by hand.

10. A transmission having an electric motor/generator, the transmission comprising:
-
a transmission housing; a bearing support rigidly connected to the transmission housing and substantially enclosed by the transmission housing; a plurality of rivets; a stator housing substantially enclosed by the transmission housing, wherein the stator housing is rigidly joined to the bearing support by the plurality of rivets, such that torque may be transferred between the stator housing and bearing support through the plurality of rivets; a stator rigidly attached to the stator housing; a rotatable bearing rigidly attached to the bearing support; and a rotor rigidly attached to the rotatable bearing, such that the rotatable bearing allows relative rotation between the bearing support and the rotor. - View Dependent Claims (11, 12, 13, 14, 15)
