摘要:
A hybrid transmission includes two electric motor modules and a plurality of planetary gear sets operatively connectable to the motor modules and to an engine. The motor modules each include integral wire connections such that as the motor modules are physically inserted into the hybrid transmission during assembly, the electrical connections may be easily established.

The present invention is drawn to a method and apparatus for cooling a hybrid transmission electric motor. More precisely, an annular chamber is formed between a housing for the electric motor and a transmission housing. Coolant is disposed in the annular chamber and is applied to the electric motor through a plurality of coolant apertures in the motor housing to cool the motor.

An improved hybrid electro-mechanical vehicular transmission includes motor/generator modules assembled from like components. This is accomplished by providing “punch-out” tabs on the motor/generator module housing enabling the housing to be used on either the first or second motor/generator module within a hybrid electro-mechanical vehicular transmission, thus enabling like components to be used within both the first and second motor/generator module.

This invention relates to grounding the mechanical loads of an electrically variable transmission with a park pawl system located in the end cover portion of the transmission housing. The end cover portion is configured to cover the park pawl system and engagement gear. A support hub is interfittable with the end cover portion of the transmission and sufficiently secured thereto so as to ground the park pawl loads. The hub also functions to guide oil to the cavity of a piston-clutch assembly. A method of securing a hub to an electrically variable transmission housing is also provided.

This invention relates to an actuable park pawl system for a hybrid electro-mechanical transmission located in the end cover portion of the transmission housing. The end cover portion is configured to cover the park pawl system and ancillary components such as the actuator guide. This enables the actuator guide to be an open-ended structure. A method of securing a park engagement system with an open-ended actuator guide in a vehicle transmission is further provided.

This invention relates to the housing of a hybrid electro-mechanical transmission consisting of park pawl system located in the end cover portion of the transmission housing. The end cover portion is configured to cover the park pawl system and allow access to the components of the park pawl system for assembly or service even as the end cover portion remains attached to the main housing of the transmission. Beyond providing coverage to the park pawl system, the end cover portion also provides structural support to a main housing portion during operation of the transmission. A method of assembling a park pawl system between main and end cover portions of a transmission housing is also provided.

This invention relates to the housing of a hybrid electro-mechanical transmission consisting of park pawl system located in the end cover portion of the transmission housing. The end cover portion is configured to cover the park pawl system and allow access to the components of the park pawl system for assembly or service even as the end cover portion remains attached to the main housing of the transmission. An access cover and seal for the access opening in the end cover portion is also provided. The access opening is designed to be small enough so that the end cover portion can also provides structural support to a main housing portion during operation of the transmission. A method of selectively providing access to a park pawl system located in the end cover portion of a transmission housing is also provided.

A preassembled wiring terminal subassembly for use in a hybrid electro-mechanical transmission includes a plurality of wires and a plurality of wire terminals each defining a respective attachment hole and being operatively connected to a respective one of the plurality of wires. The subassembly also includes a plurality of conductive rods each defining a hole, and a plurality of threaded fasteners each extending through the attachment hole of a respective wire terminal and through the hole of a respective rod. The terminals, rods, and threaded fasteners are sufficiently interconnected for movement as a unit during transmission assembly to facilitate the establishment of an electrical connection between a control unit and one or more motor/generators.

A method for establishing electrical communication between a control module and a motor/generator in a hybrid electromechanical transmission includes providing a preassembled terminal subassembly including a first plurality of wire terminals sufficiently interconnected for selective, substantially unitary movement with respect to a transmission housing, aligning the preassembled terminal subassembly with a second plurality of wire terminals affixed with respect to at least one electric motor/generator, and establishing electrical communication between each of said first plurality of wire terminals and a respective one of said second plurality of terminals.
摘要:
An electrical connector assembly for use in establishing electrical communication between a control module and a motor/generator in a hybrid electro-mechanical transmission includes an insulating wire isolator and nuts nonrotatably preassembled thereto. The electrical connector reduces the quantity of loose parts during transmission assembly. The nuts, being nonrotatably connected to the isolator, which in turn is affixed with respect to a motor housing, are able to accept torque from bolts without assisted retention.
