Patent attributes
A fire fighting vehicle includes a front axle, a rear axle, an engine, an energy storage device, an electromechanical transmission, a fluid tank configured to store a fluid, a pump configured to provide the fluid from the fluid tank to a fluid outlet, and a power divider positioned between the engine, the pump, and the electromechanical transmission. The power divider includes a first interface coupled to the engine, a second interface coupled to the pump, and a third interface coupled to the electromechanical transmission. The electromechanical transmission is (i) selectively mechanically coupled to the engine by the power divider and (ii) electrically coupled to the energy storage device to facilitate driving at least one of the front axle or the rear axle. The pump is selectively mechanically coupled to the engine by the power divider to facilitate pumping the fluid to the fluid outlet.
