Transmission for a vehicle
First Claim
1. A transmission for a vehicle, the transmission comprising:
- a casing defining a first cavity and a second cavity inside the casing;
a platform at least partially disposed inside the casing to separate the first and second cavities;
a power inverter module completely surrounded by the first cavity, and including a cooling system for cooling the power inverter module, with the cooling system defining an inlet and an outlet; and
a guide body attached to the platform and the casing, with the guide body extending outwardly away from the platform toward the second cavity, and wherein the guide body provides fluid communication between the cooling system of the power inverter module within the first cavity and outside of the casing while bypassing the second cavity;
wherein the guide body defines a first passageway extending through the platform and an outer wall of the casing for guiding a fluid from outside of the casing to the inlet of the cooling system in the first cavity and bypassing fluid communication with the second cavity;
wherein the guide body defines a second passageway spaced from the first passageway and extending through the platform and the outer wall of the casing for guiding the fluid from the outlet of the cooling system in the first cavity to outside of the casing and bypassing fluid communication with the second cavity;
wherein the first and second passageways each include a first portion extending vertically from the platform, and wherein the first and second passageways each include a second portion extending horizontally from the casing, with the first and second portions of the first passageway intersecting at a first elbow, and with the first and second portions of the second passageway intersecting at a second elbow.

Abstract
A transmission for a vehicle is disclosed. The transmission includes a casing defining a first cavity and a second cavity inside the casing, with the first cavity selectively open to outside of the casing. The transmission also includes a platform at least partially disposed inside the casing to separate the first and second cavities. Furthermore, the transmission includes a power inverter module selectively disposed in the first cavity. The power inverter module includes a cooling system for cooling the power inverter module. The transmission also includes a guide attached to the platform and the casing within the second cavity such that the guide provides fluid communication between the cooling system of the power inverter module within the first cavity and outside of the casing while bypassing the second cavity.
