The present invention pertains to a drive connection for coupling an engine to a gearbox of a machine and which provides a fluid-tight sealing. Accordingly, a drive connection for coupling an engine to a gearbox of a machine is suggested, which comprises a housing having an inner cavity that extends from a first open end of the housing to a second open end of the housing and which is configured for accommodating and enclosing a clutch. The housing defines a first coupling interface at the first open end for coupling the drive connection to an engine and a second coupling interface at the second open end for coupling the drive connection to a gearbox, Furthermore, each coupling interface comprises a sealing member, wherein the housing and sealing members are configured to fluidically seal the inner cavity, when the drive connection is in a coupled state.

A driving force transmitting device includes an axle housing and a transaxle main body. The axle housing includes a supporting body and two shafts extending in opposite directions from the supporting body. The supporting body has an internal space. The transaxle main body is supported by the supporting body. The axle housing further includes a first breather plug. The first breather plug is fixed to the supporting body and is configured to discharge a gas in the internal space to an outside. The transaxle main body includes a gear mechanism, a case that accommodates the gear mechanism, and a second breather plug. The gear mechanism is configured to transmit a driving force. The second breather plug is fixed to the case and is configured to discharge a gas in the case to the outside. The second breather plug is located in the internal space.

A portal gear box assembly for an all-terrain vehicle includes a sealed portal gear box housing having an interior housing space that contains a set of gears for linking an axle to an output shaft. An expandable space is in fluid communication with the interior housing space, and is adapted to allow pressurized fluid contained in the interior housing space to flow into the expandable space, thus expanding the volume of the expandable space and reducing the pressure within the interior housing space. The expandable space may be provided in the form of a bellows whose volume can be changed by expansion or contraction of a fluid contained therein. A fluid is contained within the portal gear box housing and within the expandable space.

The expandable space may be mounted externally to the portal gear box housing, and may be connected to the portal gear box housing by a conduit effective for allowing fluid to pass between the portal gear box housing and the expandable space. The expandable space and its connecting conduit are effective for allowing air to flow from within the portal gear box housing to the expandable space when an increased air pressure within the portal gear box is encountered, thus mitigating against a build-up of air pressure within the portal gear box housing.

A transmission for a drivetrain of a motor vehicle, including a transmission casing which is or can be at least partially filled with oil and wherein a parking lock is arranged, wherein the parking lock includes a parking lock gear, which is connected rotationally conjointly to a transmission shaft and which has a locking toothing, and a locking pawl, which is mounted pivotably on the transmission casing and which has a locking tooth which, when the locking pawl is pivoted into a locking position, can be placed in positive locking engagement with the locking toothing of the parking lock gear, wherein the locking pawl is actuatable by an electromechanical parking-lock actuator which is arranged within the transmission casing. The invention furthermore relates to a motor vehicle which has a transmission of the type.

A utility vehicle including an engine; an exhaust pipe through which exhaust gas is discharged from the engine, the exhaust pipe being connected to the engine; and an air guide that guides outside air toward the exhaust pipe.

A deaerating device is provided for a drive component in a motor vehicle. The deaerating device has an access line, a membrane deaerator, which includes a deaerating membrane, and an discharge air side. The deaerating device is designed to fluidically connect the interior of a drive component to the area surrounding the drive component. The deaerating membrane is arranged downstream of the access line and upstream of the discharge air side in a planned flow direction from the drive component into the area surrounding the drive component. The access line has an aerosol trap which has a labyrinth element for accumulating liquid on at least one wall of the labyrinth element, and the aerosol trap is designed as a separate component with respect to the access line and the membrane deaerator.

A system for and method of separating oil from crankcase air is provided. The system includes replacing a standard shaft, such as a water pump shaft, with a breather shaft of the present invention and venting crankcase air through the breather shaft to an outside volume of air, such as in an air box. The breather shaft includes a centrifuge positioned within an interior volume of the crankcase and a first portion extending from the centrifuge through a wall of the crankcase. The centrifuge defines a plurality of inlet passageways extending from an outer surface of the centrifuge towards an interior area of the centrifuge. The first portion of the breather shaft defines a venting passageway extending from the interior area of the centrifuge to a vent opening at a distal end of the breather shaft.
