Abstract
A hybrid transmission module for a work vehicle is provided. The work vehicle has a chassis and a prime mover carried by the chassis, and the hybrid transmission module includes a mounting bracket configured to mount to one or more of the chassis and the prime mover, a transmission assembly mounted to the mounting bracket, and a hydraulic-electric drive assembly including a manifold mounted to the mounting bracket. The manifold mounts a hydraulic pump and an electric machine and is configured to transfer rotational power from the prime mover to the hydraulic pump and the electric machine. The electric machine, at least in part, drives the transmission assembly.

A hybrid transmission module for a work vehicle having a chassis and a prime mover carried by the chassis, the hybrid transmission module comprising:
- a mounting bracket configured to mount to one or more of the chassis and the prime mover;
- a transmission assembly mounted to the mounting bracket;
- and
- a hydraulic-electric drive assembly including a manifold mounted to the mounting bracket, the manifold mounting a hydraulic pump and an electric machine and configured to transfer rotational power from the prime mover to the hydraulic pump and the electric machine;
- wherein the electric machine, at least in part, drives the transmission assembly.
A work vehicle comprising:
- a chassis;
- a prime mover carried by the chassis and including a rotational drive shaft for producing rotational power;
- a mounting bracket configured to mount to the chassis;
- a hydraulic-electric drive assembly including a manifold mounted to the mounting bracket, a hydraulic pump mounted to the manifold, and an electric machine mounted to ii the manifold, wherein the hydraulic-electric drive assembly is configured to transfer the rotational power from the prime mover to the hydraulic pump and the electric machine, wherein the electric machine is configured to produce direct current electrical power;
- an inverter electrically coupled to the electric machine to receive the direct current electrical power from the electric machine and output alternating current electrical power;
- and
- a transmission assembly mounted to the mounting bracket and driven by the alternating power from the inverter, wherein the inverter is mounted to the transmission assembly.
