A hybrid system includes a hybrid module that is located between an engine and a transmission. The hybrid system includes an energy storage system for storing energy from and supplying energy to the hybrid module. An inverter transfers power between the energy storage system and the hybrid module. The hybrid system also includes a cooling system, a DC-DC converter, and a high voltage tap. The hybrid module is designed to recover energy, such as during braking, as well as power the vehicle. The hybrid module includes an electrical machine (eMachine) along with electrical and mechanical pumps for circulating fluid. A clutch provides the sole operative connection between the engine and the eMachine. The hybrid system further incorporates a power take off (PTO) unit that is configured to be powered by the engine and/or the eMachine.

A transmission apparatus D that can avoid size-up of a starter through reduction of load torque required at the time of start-up of an engine, includes a traveling transmission device D1 configured to transmit power outputted from an engine 3a via a forward/reverse switching mechanism 50 acting also as a main clutch mechanism, a hydrostatic stepless speed changer mechanism 20 acting as a main speed changer mechanism, a planetary gear mechanism 40 and an auxiliary speed changer mechanism 60 to traveling components such as front wheels 1, rear wheels 2, etc., and an implement transmission device D2 configured to transmit the power outputted from the engine 3a via an implement clutch 70, an implement speed changer mechanism 71, and a PTO shaft 7 to an implement.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a water tank supported by the chassis, an energy storage system coupled to the chassis, a water pump supported by the chassis, and an electromagnetic device electrically coupled to the energy storage system. The electromagnetic device is coupled to the water pump and at least one of the front axle or the rear axle. The electromagnetic device is configured to receive stored energy from the energy storage system and provide a mechanical output to selectively drive the water pump and the at least one of the front axle or the rear axle.

A power take-off system and method is provided for a vehicle that includes an internal combustion engine, an electrical generator, an electrical machine, a power take-off summing planetary and a power take-off brake. The power take-off system includes a controller and a human-machine interface. The controller is configured to receive an input from the human-machine interface to select one of a variable speed power take-off mode, an electrical power generation mode, and a full power fixed ratio power take-off mode of operation. In the variable speed power take-off mode, electrical power from the electrical generator and rotational power by the power take-off system are output, and the electrical machine receives electricity and provides rotational power. In the electrical power generation mode, the electrical generator and the electrical machine both provide electrical power. In the full power fixed ratio mode, no electrical power is provided.

A vehicle front structure includes a left side rail that extends longitudinally in a front left portion of the vehicle. The left side rail includes an inboard shell and an outboard shell. A forward section of the outboard shell is at least partially disposed in an outer left quarter of a total width of the vehicle. A rearward section of the outboard shell is disposed inboard of the outer left quarter. The forward sections of the inboard and outboard shells each have a distal side, top side, and bottom side that respectively form generally U-shaped cross-sections. The outboard shell is fixedly attached to the inboard shell to form a generally rectangular cross-section. The forward section of the outboard shell is a first lateral width. The rearward section of the outboard shell is a second lateral width that is less than the first lateral width.

A utility vehicle with regenerative braking is disclosed. The utility vehicle includes a system power bus, a battery coupled to the system power bus, at least one electric drive motor configured to generate power through the regenerative braking and supply the power onto the system power bus, and a first controller configured to decrease a maximum travel speed to reduce an amount of the power generated through the regenerative braking when the battery is fully charged and the power is greater than a power consumption limit.

A fire fighting vehicle includes a chassis, a front axle, a rear axle, a fluid tank having a maximum fluid capacity of at least about 6,000 liters, a battery pack, and an electromechanical transmission coupled to the battery pack and at least one of the front axle or the rear axle. The electromechanical transmission includes one or more electric motors configured to receive power from the battery pack to facilitate accelerating the fire fighting vehicle from 0 to 50 miles-per-hour in 30 seconds or less while the fluid tank is at the maximum fluid capacity.

An electrified fire fighting vehicle includes a chassis, a cab, a body, a front axle, a rear axle, an energy storage system, a water pump, and an electromagnetic device electrically coupled to the energy storage system. The electromagnetic device is coupled to the water pump and at least one of the front axle or the rear axle. The electromagnetic device is configured to receive stored energy from the energy storage system and provide a mechanical output to selectively drive the water pump and the at least one of the front axle or the rear axle.

A power train for an amphibian operable in land and marine modes includes a prime mover, at least a first land propulsion unit, a first marine propulsion unit, a second marine propulsion unit, and at least one speed change transmission. The prime mover is arranged to drive the at least first land propulsion unit through/via the at least one speed change transmission in land mode, and the prime mover is arranged to drive the first marine propulsion unit and the second marine propulsion unit through/via the at least one, or another, or combinations of, speed change transmission in marine mode. In addition, the present invention provides an amphibian comprising the power train.

An engine assembly is provided that includes an engine throttle and a supercharger placed in series with one another in air flow to the engine. The throttle and supercharger can be controlled so that throttling losses are selectively distributed across the throttle and/or the supercharger. Throttling losses placed across the supercharger can create torque that can be converted to stored energy.
