In a power unit device of a vehicle in which a differential device is arranged on one side of an engine, warming-up of the engine is facilitated while heat convection from an oil pan to a differential housing is inhibited. The power unit device includes a heat insulating member that covers the outer side of an oil pan, and a differential housing that is fitted to and mounted on the oil pan. A fitting portion is provided in the differential housing, and a fitted portion is provided in the oil pan. A fitting face portion of one of the fitting portion and the fitted portion includes, at different positions in the circumferential direction, a plurality of recesses and projections in the radial direction, and is fitted to a fitting face portion of the other of the fitting portion and the fitted portion by the plurality of projections.

In a vehicle oil pan guard including a guard plate mounted on a support member via a mounting portion such that the guard plate is arranged at a position under an oil pan storing a hydraulic oil for protecting the oil pan from an impact from below, a cover plate different from the guard plate is mounted together with the guard plate via the mounting portion on the support member such that the cover plate closes an opening formed near the guard plate toward a road surface.

A gasket assembly for sealing between a first component and a second component, the first component having a main cavity separated from a secondary cavity by at least one wall, the at least one wall having an aperture formed therethrough, includes a device configured to extend through the aperture. An aperture sealing insert is molded around a portion of the device, the aperture sealing insert sized and shaped to fit into the aperture. An aperture seal is disposed about an outer perimeter surface of the aperture sealing insert, the aperture seal configured to seal against surfaces defining the aperture. A gasket baseplate is configured to be disposed over the aperture sealing insert between the first component and the second component to fluidly seal the main cavity from the secondary cavity while enabling the device to pass through the aperture.

A hybrid oil pan for a vehicle includes a body part which is molded with a plastic material to reduce the weight, and a portion of the oil pan that is fastened to a transmission has increased dynamic rigidity to cope with the deformation caused by the dynamic behavior of the transmission.

The present disclosure describes an oil pan structure including a storing portion that stores oil for an internal combustion engine. The storing portion includes a shallow bottom portion, a deep bottom portion deeper than the shallow bottom portion, and a connection surface that connects the shallow bottom portion and the deep bottom portion between the shallow bottom portion and the deep bottom portion. A side wall is formed at a position facing the connection surface with the shallow bottom portion interposed between the side wall and the connection surface. A rib is formed on a back surface of the shallow bottom portion so as to extend from one side or another side of the side wall in a width direction of the shallow bottom portion toward an end portion of the connection surface on an opposite side in the width direction.

Methods and systems are provided for a cooling device connected to components of a motor vehicle. The cooling device influencing a fluid flow moving past the vehicle components. In one example, a system may include a cooling device positioned below an oil sump. The cooling device may feature an apparatus such that a fluid flows between the apparatus and oil sump. The cooling device may also be positioned below a transmission housing.

An engine mounting assembly includes a front frame element defining, in part, a structural load bearing assembly, a differential case mounted to the frame at a frame mounting area, and an oil pan having upright and bottom walls defining an oil sump. The differential case has an opening configured to receive an axle assembly and has walls defining a pan-receiving recess. The oil pan is configured to conform to the pan-receiving recess to be supported by the differential case and overlap the frame mounting area. The oil pan has a mounting flange extending from the upright walls and mounting bores that receives mounting bolts for coupling the oil pan to the engine and the oil pan to the differential case. The differential case and the oil pan form part of the structural load bearing assembly of the work vehicle to transfer structural loads to and from the front frame element.

An agricultural vehicle transmission may comprise a housing comprising a bulkhead where the bulkhead may divide the housing into a sump and a reservoir. The bulkhead may comprise an opening configured to fluidly couple the sump and the reservoir. A plurality of transmission gears may be disposed in the reservoir of the housing. The opening in the bulkhead may balance the vehicle transmission system to remove excess oil in the sump and away from the plurality of transmission gears.

To achieve an improved rigidity, the an oil pan (3) for forming a lower end part of an internal combustion engine (1) comprises a bottom wall (6) and a side wall (7) extending from a peripheral edge of the bottom wall, wherein the bottom wall includes a pair of first planar surface portions (35) extending in a lateral direction and provided on either end of the bottom wall with respect to a fore and aft direction orthogonal to the lateral direction, and a curved surface portion (36) recessed downward with respect to the first planar surface portions.

An oil pan assembly for an engine may include: an oil pan mounted at a lower portion of a cylinder block of the engine and formed with a space therein, in which oil can be stored; and a support bracket mounted at one side of the oil pan for coupling with an air conditioner compressor or a transmission. In particular, a protrusion portion is formed at an upper surface of the support bracket and upwardly protruded.
