STATOR CAN HOUSING WELDED TO BEARING SUPPORT AND METHOD OF ASSEMBLING A HYBRID TRANSMISSION UTILIZING THE SAME |
摘要 |
A motor/generator for a hybrid transmission includes a bearing support configured for attachment to the hybrid transmission. A stator can is bonded directly to the bearing support, possibly by welding. The motor/generator may further include a stator press-fit into said stator can. A method of assembling a hybrid transmission includes welding a stator can to a bearing support, forming a motor/generator housing. A stator is then pressed into the housing. A substantially-complete motor/generator is assembled by installing a rotor, a rotor hub, and a ball bearing into the housing, which are held in the motor/generator housing with a snap ring. The method may include rigidly attaching the substantially-complete motor/generator to a main case. The method may further include testing the substantially-complete motor/generator prior to transporting the motor/generator to a final place of assembly and rigidly attaching the motor/generator to the transmission main case.
