Abstract: A firefighting vehicle includes a chassis that houses an electric drivetrain for driving wheels of the vehicle. A conduit extends within the chassis from back to front for conveying firefighting fluid. Within the chassis, a first motor and a first battery pack are disposed on a first side of the conduit and a second motor and a second battery pack are disposed on a second side of the conduit. The first motor is configured to drive a first wheel on a first side of the vehicle, and the second motor is configured to drive a second wheel on a second side of the vehicle. The conduit is configured to provide firefighting fluid to a monitor mounted at the front of the chassis, where the fluid can be discharged toward a target, such as a fire.

Abstract: A universal mounting structure for changing attachments on a construction machine includes first and second ear plates mounted disposed in spaced relation. The ear plates include a first and second pair portions of elongated cutout patterns. First and second collar/pin assembly each includes a pin and a pair of collars. Each collar has an eccentric bore configured to removably receive each end of a pin and each collar has surfaces engaging complementary surfaces of one of the first or second pair portions of the elongated cutout patterns. The first and second collar/pin assemblies are configured such that a center distance between the pins can be adjusted 1) in large increments by moving either one or both of the first and second collar/pin assemblies within the respective pair portion of the elongated cutout patterns, and 2) in small increments by axial rotation of a pair of collars about a respective pin of one or both of the collar/pin assemblies.

Abstract: A vehicle includes a body defining a front, a rear, lateral sides extending between the front and the rear. The vehicle further includes a fluid delivery system supported by the body. The fluid delivery system includes an intake manifold disposed at the rear, the intake manifold being constructed and arranged to receive fluid from at least one external fluid source, an outlet disposed at the front, the outlet being constructed and arranged to distribute fluid from the at least one fluid source to an external target, and a fluid conduit coupled with the intake manifold and the outlet to convey the fluid from the intake manifold to the outlet through the body. The vehicle further includes track assemblies coupled with the body, the body being disposed between the track assemblies to enable the track assemblies to provide stability to the vehicle during high speed fluid discharge from the outlet.

Abstract: A technique for a modular tracked vehicle that can be reconfigured as needed to address different requirements and use cases. The modular tracked vehicle includes a chassis hull that allows interchangeable components to be connected thereto. The interchangeable components include interchangeable final drives which drive the vehicle's tracks. The chassis hull stores an energy reservoir, such as a battery or fuel tank, and the final drives include at least a gear box and drive axle. Different final drives may be provided for different torque levels, speed levels, energy sources, and or other specifications, and the final drives may be swapped based on mission requirements. Other components of the modular tracked vehicle may be interchangeable, as well. The technique may be provided, for example, as a modular tracked vehicle, a platform for a modular tracked vehicle, and/or as a method for use with a modular tracked vehicle.

Abstract: A technique provides an amphibious, submersible vehicle, which includes an electric drive and is capable of operating both on land and in water. The vehicle includes a water-tight compartment that houses batteries and a set of electric motors for propelling the vehicle using tracks on land and on a subsea floor. The vehicle is further capable of propelling itself through water, using the tracks and/or a set of thrusters powered by the batteries.

Abstract: Techniques are directed to utilizing a suspension protector to deflect debris away from a set of suspension components of a tracked vehicle. The tracked vehicle includes a vehicle body, a suspension, and a set of suspension protectors. The suspension couples with the vehicle body and is constructed and arranged to control movement of the vehicle body using tracks. Each suspension protector couples with the vehicle body and is disposed a predefined distance from a respective wheel of the suspension to deflect debris thrown from the respective wheel and a respective track away from a respective set of suspension components of the suspension.

Abstract: A technique for steering a tracked vehicle includes controllably deforming at least a portion of a vehicle's track into a curved shape, causing the vehicle to follow a curve-shaped path as it drives. As the vehicle naturally tends to follow a curved path defined by the track's curvature, steering is accomplished with greatly reduced skidding against the ground.

Abstract: Example apparatuses and techniques are disclosed for towing tracked vehicles at high speeds without various deficiencies and for allowing a vehicle to be configured to extend supplemental wheels from a storage configuration into a ground support configuration in which the vehicle is able to make use of the supplemental wheels for additional ground support.

Abstract: Example techniques have been presented for providing tracked vehicles with deployable towing wheels. Such techniques involve a track vehicle having a vehicle body, a track coupled to the vehicle body, and a wheel assembly coupled to the vehicle body. The wheel assembly includes a wheel and is operable to assume a towing position in which at least a portion of the wheel extends below the track and enables the tracked vehicle to be towed on the wheel without the track making ground contact.

Abstract: A vehicle includes a floor plate defining a front and a back of the vehicle, wall sections to receive vehicle loading and transfer the vehicle loading to the floor plate, and a fluid delivery assembly supported by the floor plate. The fluid delivery assembly includes an intake manifold that resides at the back, an outlet that resides at the front, and a set of lateral conduits extending between the intake manifold and the outlet to laterally convey fluid entering the intake manifold from a fluid source to the outlet for delivery to a fluid target. Accordingly, the back may connect to the fluid source and the front may deliver the fluid thus keeping the vehicle sides and top available for other uses. Moreover, the low isolated placement of the fluid delivery assembly safeguards the fluid delivery assembly and provides a low center of gravity for vehicle stability.
