A driveline includes a driver configured to be positioned between an engine and a transmission. The driver includes a housing, a motor/generator, and a clutch. The housing includes an engine mount configured to couple to the engine and a backing plate configured to couple to the transmission. The motor/generator is disposed within the housing and configured to couple to an input of the transmission. The clutch is disposed within the housing and coupled to the motor/generator. The clutch is configured to selectively couple an output of the engine to the motor/generator. The clutch is configured to be spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto.

A system for repositioning at least one battery of an electric-powered vehicle relative to a drive axle of the vehicle to increase the weight carried by the axle as the vehicle attains a predetermined speed.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.

An active grille system having a linear actuation mechanism. The active grille system has vanes connected to a link arm. The vanes rotate between an open position and a closed position using force transmitted by the link arm. Connected to the frame is an actuator that has a mover that provides force to a linear actuation mechanism that is connected to the link arm.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.

A military vehicle including an engine coupled to the chassis for providing mechanical power to the military vehicle, a motor/generator coupled to the engine, and an energy storage system including a battery electrically coupled to the motor/generator. The military vehicle is operable in a silent mobility mode with the engine inactive and the energy storage system providing power to the motor/generator to operate the military vehicle. The motor/generator and the battery are sized such that electrical power generation through engine drive of the motor/generator is greater than the power depletion through operation of the military vehicle in the silent mobility mode. The motor/generator can charge the energy storage system while the military vehicle is driving or stationary.

A military vehicle includes a chassis, a front end accessory drive (FEAD), and circuitry. The chassis includes an engine and an integrated motor generator (IMG). The FEAD includes multiple accessories and an electric motor-generator. The circuitry is configured to operate the military vehicle according to different modes. The circuitry is configured to receive a user input indicating a selected mode of the modes, and operate the chassis and the FEAD of the military vehicle according to the selected mode. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and the tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.

Differential arrangement, e.g., for a drive axle of a motor vehicle. The differential arrangement comprises a drive wheel; a differential gear having an input part; a shift clutch operatively arranged between the drive wheel and the differential gear, wherein in the closed state of the shift clutch torque is transmitted from the drive wheel to the differential gear and in the open state of the shift clutch a torque transmission is interrupted. A first clutch part of the shift clutch is fixedly connected to the input part or to a differential housing of the differential gear, and a second clutch part of the shift clutch is fixedly connected to the respective other one of the input part and the differential housing.

A military vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, and a driveline. The driveline includes an engine, an energy storage system, a front end accessory drive positioned in front of and coupled to the engine, a transmission coupled to at least one of the front axle or the rear axle, a second motor coupled to the transmission and electrically coupled to the energy storage system, and a clutch positioned between the engine and the second motor. The front end accessory drive includes an air compressor and a first motor. The first motor is electrically coupled to the energy storage system. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto based on operation of the air compressor. The driveline is operable in an engine-only mode and an electric-only mode.

Methods and systems are provided for a detachable fuel pipe of a vehicle fuel system. In one example, a method may include, in response to a detected vehicle collision, removing physical and fluidic couplings between the detachable fuel pipe and a fuel tank. The method may further include sealing the fuel tank upon removing the couplings to the detachable fuel pipe.
