Methods and systems for an electric drive assembly are provided herein. In one example, an electric drive system is provided that includes two multi-motor drive units with associated planetary gear reductions that have asymmetric gear ratios. The planetary gear reduction in each drive unit includes a ring gear and a sun gear that are rotationally coupled to a pair of motors and a carrier rotationally coupled to an output gear that interfaces with a gear reduction of an axle assembly.

An electric work vehicle includes a mounted body enabling execution of a specific work. The electric work vehicle further includes a main frame, a cab in a front portion of the main frame, an electrical component unit on the main frame in a position lower than a lower surface of the cab, and a power take off (PTO) unit having a work machine drive unit for driving a work machine to execute the specific work by the mounted body, and a mounted motor for supplying rotational power, by electric power of the battery, to the work machine drive unit. In the PTO unit, the mounted motor is in a position lower than the lower surface of the cab and in a lowermost layer region of a space where the electrical component unit is disposed, and the work machine drive unit is disposed in a position rearward from the mounted motor.

The invention relates to a cooling system for a vehicle, the cooling system comprising a cooling fan comprising a ram air turbine disposed in an aperture of a fan shroud, the fan shroud comprising: an opening, a shutter mechanism movable between a closed position in which it closes the opening, and an open position in which it opens the opening so that a ram air flow can pass through the opening, wherein the fan shroud further comprises: a velocity sensor configured to measure ram air flow velocity, a temperature sensor configured to measure ram air flow temperature, and an actuator configured to move the shutter mechanism between the closed position and the open position based on measured ram air flow velocity and measured ram air flow temperature.

The invention relates to a vehicle powertrain, comprising: first and second power units (PUs), a propeller shaft, (PS) a power take-off, (PTO), a transmission comprising: first and second input shafts connected to the PUs, an output shaft connected to the PS, and a countershaft connected to the PTO, first and second input shaft gearwheels (ISGs) on the input shafts, first and second countershaft gearwheels (CSGs), the first CSG being in driving connection with the second ISG, first, second and third output shaft gearwheels (OSGs) in driving connection with the first ISG and the first and second CSGs, first and second gear engaging devices (GEDs), wherein, in a mode of operation, the first GED rotationally connects the first OS G to the output shaft, and the second GED rotationally disconnects the output shaft from the second and third OSGs, no parts of the powertrain being drivingly connected to both of the PUs.

An electrified vehicle, comprising a chassis having a frame, a first tractive element, and a first suspension system coupled with the first tractive element and the chassis. The first suspension system may comprise a first knuckle coupled with the first tractive element, and a first strut-damper coupled with the first knuckle and the chassis, the first strut-damper extending between the chassis and the first knuckle. The first suspension system may also include a first control arm coupled with the first knuckle and the frame member, and a torsion bar coupled with the chassis at a first end of the torsion bar. The torsion bar may extend in a direction substantially parallel with the frame member, where the torsion bar may be configured to support a portion of a mass of the electrified vehicle in response to displacement of the first tractive element relative to the chassis.

A vehicle includes a chassis, a cab coupled to the chassis, a prime mover coupled to the chassis and positioned at least one of beneath or behind the cab, and an accessory drive. The accessory drive includes an accessory and connecting shaft. The accessory is positioned forward of a front of the cab such that the accessory is spaced from the prime mover. The connecting shaft extends from the prime mover, past the front of the cab, and to the accessory. The connecting shaft is positioned to facilitate driving the accessory with the prime mover.

A vehicle system for a vehicle includes a controller. The controller is configured to transmit a first control signal to a transmission of the vehicle to engage a first gear of the transmission, acquire information regarding a pressure of an inlet flow of water received by a pumping system of the vehicle, and transmit a second control signal to the transmission to engage a second gear of the transmission based on the information.

A compartment for storing fuel in a vehicle having a protective outer structure and an inner structure. The protective outer structure is maintained in position relative to the vehicle during normal operation of the vehicle. The inner structure, which holds fuel, is positioned in the outer structure. The inner structure is maintained in position relative to the outer structure and relative to the vehicle during normal operation of the vehicle. During an impact to the vehicle, the inner structure is configured to move independent of the outer structure.

Systems and methods are described for securely monitoring a shipping container for an environmental anomaly using elements of a wireless node network of sensor-based ID nodes disposed within the container and a command node associated with the container. The method has the command node identifying which of the ID nodes are confirmed as trusted sensors based upon a security credential specific to each of the ID nodes; monitoring only the confirmed ID nodes for sensor data broadcast those ID nodes; detecting the anomaly based upon the sensor data from at least one of the confirmed ID nodes; automatically generating an alert notification related to the detected environmental anomaly for the shipping container; and transmitting the alert notification to the external transceiver to initiate a mediation response related to the detected environmental anomaly.

A hubcap for a heavy-duty duty vehicle that includes mounting structure that is formed with and cooperates with a side wall of the hubcap to provide a stiff, rigid structure that enables non-cantilevered connection to a wheel hub. The mounting structure can be a plurality of elongated bosses circumferentially spaced about the side wall that are formed with corresponding elongated bolt openings to enable the non-cantilevered attachment to the wheel hub. The elongated bosses cooperate with the hubcap side wall to provide a stiffened or rigid structure between the elongated bolt openings for increased and more uniform clamping force on a sealing gasket between the hubcap and the wheel hub. The hubcap profile provides clearance for removal of an outboard mounted disc brake rotor in heavy-duty vehicle wheel end assemblies that include such rotor configurations. The hubcap may support simple mounting of a hub odometer.
