A vehicle drive device including an engagement pressure flow channel, a lubrication flow channel, a first pump having a discharge port connected to the engagement pressure flow channel, a second pump, and a flow channel control valve. The flow channel control valve selectively switches flow channels between a first state in which an outflow destination of oil discharged from the second pump is the engagement pressure flow channel and a second state in which the outflow destination is the lubrication flow channel. When a failure in which the flow channel control valve is fixed in the second state has occurred, a control device for a vehicle control device performs fail-safe control in which a rotational speed of at least one of an internal combustion engine and a rotating electrical machine is increased to supply oil to the engagement pressure flow channel by the first pump.

An on-demand four-wheel drive system includes a differential for the rear axle, a differential for the front axle, and a center differential connecting to the front and rear axle differentials. All three of the differentials contain a bi-directional overrunning roller clutch to enable locking of their respective outputs. The clutches provide a superior on-demand four-wheel drive system that distributes power to each drive wheel to propel the vehicle.

The drive power connecting/disconnecting device includes a second shaft disposed coaxially to a first shaft so as to transmit drive power to a wheel axle, a connection/disconnection member which moves a second rotational body along an axial direction with respect to a first rotational body, and which is capable of moving in the axial direction so as to make or break engagement between the first shaft and the second shaft, a supporting member, a shaft cover which covers at least the periphery of the second rotational body, a first pivotally supporting portion which is disposed between the first shaft and the second shaft so as to axially support one end of the second shaft; and a second pivotally supporting portion which is disposed inside the shaft cover so as to axially support the other end of the second shaft.

The present invention discloses an operating fluid container for a motor vehicle, wherein the operating fluid container comprises a fill level sensor, a tank control device and an electrically and/or electromagnetically actuable actuator; the tank control device is connected to the actuator by means of a first data exchange connection and to the fill level sensor by means of a second data exchange connection; the fill level sensor is designed to transmit data representing a fill level of the operating fluid container to the tank control device via the second data exchange connection; the tank control device is designed to transmit a filling stop signal to the actuator via the first data exchange connection upon receiving data which represent a predetermined fill level of the operating fluid container; and the actuator initiates the termination of a filling procedure of the operating fluid container upon receiving the filling stop signal.

A valve assembly for a fuel tank system including a fuel tank having a fuel tank outlet and a purge canister includes a main valve and a safety check valve. The main valve can be configured to move from a closed position to an open position. The main valve can have a main valve first port fluidly coupled to the outlet of the fuel tank and a main valve second port fluidly connected to the purge canister. The safety check valve can be configured to move from an open position to a closed position upon a pressure drop at the fuel tank outlet exceeding a predetermined threshold. The safety check valve can have a safety check valve first port fluidly coupled to the outlet of the fuel tank and a safety check valve second port fluidly coupled to the purge canister.

The present invention discloses a locking device, a power assembly, a power transmission system and a vehicle. The locking device includes: a first flange, the first flange being adapted to be fixed on the first shaft; a second flange, the second flange being adapted to be fixed on the second shaft; a synchronizing ring, the synchronizing ring being normally connected to the first flange to be adapted to rotate synchronously with the first flange, and the synchronizing ring being slidable relative to the first flange; and a driving component, the driving component selectively pushing the synchronizing ring to slide from an unlocked position to a locked position in an axial direction of the first flange. When the synchronizing ring is in the locked position, the synchronizing ring is connected to the second flange be adapted to rotate the second flange synchronously with the first flange. When the synchronizing ring is in the unlocked position, the synchronizing ring is separated from the second flange. The locking device according to embodiments of the present invention can realize the single-way locking function, and is simple in structure.

The drive power connecting/disconnecting device includes a second shaft disposed coaxially to a first shaft so as to transmit drive power to a wheel axle, a connection/disconnection member which moves a second rotational body along an axial direction with respect to a first rotational body, and which is capable of moving in the axial direction so as to make or break engagement between the first shaft and the second shaft, a supporting member, a shaft cover which covers at least the periphery of the second rotational body, a first pivotally supporting portion which is disposed between the first shaft and the second shaft so as to axially support one end of the second shaft; and a second pivotally supporting portion which is disposed inside the shaft cover so as to axially support the other end of the second shaft.

A valve assembly for a fuel tank system including a fuel tank having a fuel tank outlet and a purge canister includes a main valve and a safety check valve. The main valve can be configured to move from a closed position to an open position. The main valve can have a main valve first port fluidly coupled to the outlet of the fuel tank and a main valve second port fluidly connected to the purge canister. The safety check valve can be configured to move from an open position to a closed position upon a pressure drop at the fuel tank outlet exceeding a predetermined threshold. The safety check valve can have a safety check valve first port fluidly coupled to the outlet of the fuel tank and a safety check valve second port fluidly coupled to the purge canister.
