A motor for an electric vehicle includes a motor housing for receiving a stator. A plurality of caps each have an outer rim and a washer portion defining a bolt receiving opening. The outer rim of each of the caps is press-fit into the receptacles in the motor housing. The caps are each attached to the stator by one of the bolts. The heads of the bolts clamp the cap to the stator to retain one end of the stator. The outer rim holds the cap in the motor housing while the washer portion flexes axially in response to thermal expansion and contraction of the motor housing. A method is disclosed for assembling the stator into the motor housing.

Stator free end retainer

A vehicle transaxle includes a housing, an electric machine stator, a plurality of mounting plates, and a first set of fasteners. The housing has internal walls that define a cavity and an access opening to the cavity. The electric machine stator is disposed within the cavity between a first of the internal walls and the opening. The plurality of mounting plates secures a first longitudinal end of the stator to the housing proximate the opening. Each fastener of the first set of fasteners extends through one of the mounting plates, through the stator, and engages the first of the internal walls to secure a second longitudinal end of the stator to the first of the internal walls.

Hybrid/electric vehicle transmission

A vehicle transmission includes a housing, an electric machine stator, a support plate, and a plurality of fasteners. The housing has an internal rear wall and a side wall that define a cavity. The electric machine stator is disposed within the cavity. The support plate is disposed within the cavity. The support plate engages the internal side wall such that a press-fit engagement is formed between the support plate and the internal side wall. The electric machine is disposed between the support plate and the internal rear wall. The plurality of fasteners extends through the support plate, through the stator, and engages the rear internal wall to secure the stator to the housing.

A vehicle transmission includes a housing, an electric machine, a bracket, and a plurality of fasteners. The housing has internal rear and internal side walls that define a cavity. The electric machine stator and the bracket are disposed within the cavity. The bracket has a metallic inner ring and an elastomer outer ring. The elastomer outer ring engages the internal side wall. The electric machine stator is disposed between the bracket and the internal rear wall. The plurality of fasteners extends through the metallic inner ring, through the stator, and engages the rear internal wall to secure the stator to the housing.
