Hybrid electric powertrain for tracked vehicles

A hybrid electric powertrain system for tracked vehicles, comprising:

• a left track and a right track;
• a left planetary gear assembly and a right planetary gear assembly, each planetary gear assembly including a sun gear and planetary gears;
• electric motors operatively connected to reduction gears, which engage with the planetary gear assemblies;
• a battery providing electrical power to the electric motors;
• carrier shafts extending from each planetary gear assembly and connecting to drive sprockets that engage with and drive the left track and right track;
• an internal combustion engine providing mechanical power through a first output gear shaft that connects to a second output gear shaft, which connects to a third output gear shaft through a reverse gear;
• an axle housing supporting an axle, which is further supported by an axle support;
• a central motor positioned to provide additional power input to the system;
• an outside brake assembly providing control over component rotation;
• and,
• an axle brake that may be engaged to prevent rotation of the axle.

A hybrid electric powertrain system for tracked vehicles, comprising:

• a left track and a right track driven by corresponding left planetary gear assembly and right planetary gear assembly, each planetary gear assembly including a sun gear, planetary gears, and a ring gear;
• electric motors operatively connected to reduction gears, which engage with the ring gears of the planetary gear assemblies;
• a battery providing electrical power to the electric motors;
• carrier shafts extending from each planetary gear assembly and connecting to drive sprockets that engage with and drive the left track and right track;
• an internal combustion engine providing mechanical power through the system configuration;
• a reverse gear allowing for forward and reverse operation of the mechanical power transmission;
• an outside brake assembly and a ring brake assembly providing enhanced control capabilities for component rotation;
• and
• a central motor positioned to provide additional power input to the system through a gear interface connection.
