Support for a stator of an electric machine for a hybrid electric transmission

Abstract

An assembly for supporting a motor of a vehicle powertrain includes a casing covering transmission gearing including an opening and a mounting surface surrounding the opening, a stator secured to the casing, including a reference surface spaced from an axis, and a terminal assembly seated on the mounting surface and secured to the casing, including a terminal electrically connected to the stator through a current conductor.

What is claimed is: 
     
         1 . An assembly for supporting a motor of a vehicle powertrain, comprising:
 a casing covering transmission gearing, including an opening and a mounting surface surrounding the opening;   a stator secured to the casing, including a reference surface spaced from an axis;   a terminal assembly seated on the mounting surface and secured to the casing, including a terminal electrically connected to the stator through a current conductor.   
     
     
         2 . The assembly of  claim 1 , wherein the conductor is flexible in flexure, such that a distance between the axis and the reference surface is substantially unchanged by producing said connection. 
     
     
         3 . The assembly of  claim 2 , wherein each conductor is flexible in flexure, such that said distance is substantially unchanged by producing said connections. 
     
     
         4 . The assembly of  claim 1 , wherein:
 the stator is secured by mechanical fasteners to an inner surface of the casing, such that the reference surface is spaced by a predetermined distance from the axis.   
     
     
         5 . The assembly of  claim 1 , wherein:
 the terminal assembly includes a block seated on the mounting surface and secured to the casing by second mechanical fasteners, the block supporting electrical terminals, each terminal being connectable to the stator.   
     
     
         6 . The assembly of  claim 1 , wherein the terminal assembly includes:
 a block seated on the mounting surface;   terminals supported on the block;   second mechanical fasteners for securing the terminals and the block to the casing.   
     
     
         7 . The assembly of  claim 1 , wherein the terminal assembly includes:
 a block seated on the mounting surface;   terminals supported on the block;   second mechanical fasteners for securing the terminals and the block to the casing;   receptacles electrical connected to the terminals by third mechanical fasteners;   conductors, each conductor electrically connected to one of the receptacles and the stator.   
     
     
         8 . An assembly for supporting a motor of a vehicle powertrain, comprising:
 a casing at least partially enclosing transmission gearing, including an opening and a mounting surface surrounding the opening;   a stator secured to the casing, including a reference surface spaced radially from an axis;   a terminal assembly seated on the mounting surface and secured to the casing, including a terminals, each terminal electrically connected to the stator through a current conductor.   
     
     
         9 . The assembly of  claim 8 , wherein:
 the stator includes a reference surface, and is secured by mechanical fasteners to an inner surface of the casing, such that the reference surface is spaced by a predetermined distance from the axis.   
     
     
         10 . The assembly of  claim 8 , wherein:
 the terminal assembly includes a block seated on the mounting surface and secured to the casing by second mechanical fasteners, the block supporting the terminals.   
     
     
         11 . The assembly of  claim 8 , wherein the terminal assembly includes:
 a block seated on the mounting surface, the terminal supported on the block;   second mechanical fasteners for securing the terminals and the block to the casing.   
     
     
         12 . The assembly of  claim 8 , wherein the terminal assembly includes:
 a block seated on the mounting surface, the terminal supported on the block;   second mechanical fasteners for securing the terminals and the block to the casing;   receptacles electrical connected to the terminals by third mechanical fasteners;   conductors, each conductor electrically connected to one of the receptacles and the stator.
