Electrified fire fighting vehicle

A fire fighting vehicle comprising:

• a chassis;
• a front axle coupled to the chassis;
• a rear axle coupled to the chassis;
• an engine;
• an energy storage device;
• an electromechanical transmission configured to drive at least one of the front axle or the rear axle, the electromechanical transmission including a power-take-off;
• a pump system;
• a power divider including:
• a first interface coupled to the engine;
• a second interface coupled to the pump system;
• a third interface coupled to the electromechanical transmission;
• a first clutch coupled to the pump system;
• and
• a second clutch coupled to the electromechanical transmission;
• and
• a hydrostatic transmission coupled to the electromechanical transmission, the hydrostatic transmission driven by the power-take-off to drive the pump system.

• an electromechanical transmission configured to drive at least one of the front axle or the rear axle;
• a pump system comprising:
• a water pump configured to pump a fluid from a fluid source to a fluid outlet;
• and
• a water pump drivetrain coupled to the water pump;
• a power divider positioned between and coupled to the engine, the pump system, and the electromechanical transmission;
• and
• a hydrostatic transmission including:
• a hydrostatic pump coupled to the electromechanical transmission by a first shaft;
• and
• a hydrostatic motor fluidly coupled to the hydrostatic pump, the hydrostatic motor coupled to the water pump drivetrain by a second shaft, wherein the hydrostatic pump is driven with the electromechanical transmission to pump hydraulic fluid to the hydrostatic motor to drive the water pump of the pump system.
