Transmission for a vehicle and a method of assembling a modular motor assembly in the transmission

摘要

A transmission for a vehicle and a method of assembling a modular motor assembly in the transmission are disclosed. The transmission includes a housing defining a cavity along a longitudinal axis. The transmission further includes a first motor/generator and a second motor/generator each disposed in the cavity. The transmission also includes a first support supporting the first motor/generator such that the first motor/generator is mounted to the first support to define a first modular unit. The first modular unit is attached to the housing within the cavity. The transmission further includes a second support supporting the second motor/generator such that the second motor/generator is mounted to the second support to define a second modular unit. The second modular unit is attached to the first modular unit such that the first and second modular units align with each other along the longitudinal axis within the cavity of the housing.

1. A transmission for a vehicle, the transmission comprising:
a housing defining a cavity along a longitudinal axis; a first motor/generator and a second motor/generator each disposed in the cavity; a first support supporting the first motor/generator such that the first motor/generator is mounted to the first support to define a first modular unit, with the first modular unit attached to the housing within the cavity; a second support supporting the second motor/generator such that the second motor/generator is mounted to the second support to define a second modular unit, with the second modular unit attached to the first modular unit such that the first and second modular units align with each other along the longitudinal axis within the cavity of the housing; and wherein the first and second motor/generators each include a rotor, a stator and a resolver, with the rotor, the stator and the resolver of the first motor/generator coupled to the first support to further define the first modular unit, and the rotor, the stator and the resolver of the second motor/generator coupled to the second support to further define the second modular unit; wherein the stator of the second motor/generator includes a second mounting flange attached to the second support to secure the second motor/generator to the second support; wherein the second support includes a second extension extending toward the first modular unit, with the second extension aligning with the second mounting flange, and further including a second fastener disposed through the second extension and the second mounting flange to secure the second motor/generator and the second support to each other.
