A hydraulic drive system is provided and generally includes a first rotor assembly arranged along a first side of the frame and having a first rotor and a first drive shaft extending through and connectable with the first rotor, a first motor assembly disposed along the first side of the frame and positioned linearly the first rotor assembly and a second rotor assembly arranged along a second side of the frame that is opposite the first side and having a second rotor and a second drive shaft extending through and connectable with the second rotor.

A vehicle uses a plurality of momentum generators to accelerate. The momentum generator may comprise an arm bearing weights that may be mounted to a frame and arranged to pivot in circular motion. A power source rotates the arm which encounters a stop before rotating half of a full turn. The power source may act continually on the arm, with the arm being released to rotate by a detent mechanism. Momentum of the arm and weights is transferred by the stop to the frame. Direction of rotation is selected to move the frame in a predetermined direction. The vehicle may be wheeled or may be flight capable. If flight capable, the vehicle may have a primary power source such as a rocket motor, with the momentum generators being disposed to increase velocity beyond that produced by the rocket motor. Momentum generators are preferably provided in pairs arranged in mirror image opposition so that operation does not impose unbalanced forces on the vehicle.

This disclosure details electrified vehicles that are equipped with removable generators for increasing the electric range of the vehicles. An exemplary electrified vehicle includes a cargo space, such as a truck bed, and a generator removably positioned within the cargo space. The generator is adapted to selectively supply power for either charging a battery pack of the electrified vehicle or for propelling one or more vehicle drive wheels. In some embodiments, the generator is shaped like, and therefore disguised as, a toolbox.

A vehicle includes an electric load, a first battery electrically connected to the electric load, a second battery electrically connected to the electric load in parallel with the first battery, the second battery being closer to a center of the vehicle than the first battery in a top view of the vehicle, a switch configured to electrically disconnect solely the first battery of the first battery and the second battery from the electric load, and a controller configured to open the switch based on detection of a collision of the vehicle or detection of an abnormality of the first battery.

Vehicles may be composed of a relatively few number of modules that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

Disclosed is a hydraulic drive system for a vehicle, which system comprises a hydraulic motor, at least one hydraulic pump, at least one low voltage electric motor, at least one low voltage battery and at least one low voltage fuel cell.

A drive line arrangement for self-propelled agricultural product applicator includes an engine connected to a remotely mounted pump arrangement by a driveshaft that passes through an axle of a frame of the applicator. The axle includes an axle tube extending transversely across the frame and defining front and rear facing surfaces of the axle tube, and a tubular-shaped tunnel fixedly attached to and extending through the axle from the front to the rear facing surfaces of the axle tube, and defining an internal opening of the tunnel for passage of the driveshaft through the tunnel. The tunnel extends beyond at least one of the front and rear facing surfaces of the axle tube to structurally reinforce the axle tube around the opening in the tunnel.
