A power transmission device includes a motor, a gear mechanism connected downstream of the motor and lubricated by oil, and a box. The box has a wall part that covers an outer circumference of the gear mechanism, and a jacket part that covers an outer circumference of the wall part. A cooling chamber, in which cooling liquid is introduced, is formed between the wall part and the jacket part. The cooling chamber includes a portion that overlaps with the gear mechanism when seen from a radial direction, and a portion that overlaps the gear mechanism when seen from an axial direction.

A heat exchanger having a stack of nested shells joined to a base plate includes two coolant manifolds and four fluid manifolds extending through the stack. The coolant manifolds extend the entire length of the stack in the stacking direction. Two of the fluid manifolds extend from one end of the stack to an intermediate location along the stacking direction, and the other two fluid manifolds extend from the other end of the stack to the intermediate location. Fluid transfer conduits extend through the stack, from a face of the base plate opposite the stack to the fluid manifolds at the end of the stack opposite the base plate, in order to transfer fluid to and from fluid flow passages extending between those fluid manifolds at that end of the stack.

The invention relates to a lubricating oil deflector for a speed reduction gear of a turbomachine, the deflector comprising a body having a first end intended to be disposed facing a sun gear of the reduction gear, the first end being configured to receive oil from the sun gear and an opposite second end configured to discharge the oil from the body, the body including two side faces each intended to be disposed facing a planet gear of the reduction gear and each connecting the first and second ends together, the body including at least one inner oil guide channel that opens out at the first end and at the second end and is configured to discharge the oil by gravity through the second end.

A utility vehicle includes a plurality of ground-engaging members, a frame supported by the ground-engaging members, and a plurality of body panels supported by the frame. The utility vehicle also includes a radiator supported on a rear portion of the frame. Additionally, the utility vehicle includes an air intake assembly partially supported by an upper portion of the frame.

A drivetrain system includes a housing configured to at least partially contain a liquid lubricant such as oil that flows through a gearset. Within the housing is arranged a plurality of bearings configured to constrain respective trajectories of respective shafts. An inner surface of the housing includes a first region surrounding a motor gear bearing that is actively cooled by a coolant. The inner surface also includes a second region that is distal to the motor gear bearing and that is not actively cooled by the coolant. Cooling pins are arranged in the first region and are configured to provide heat transfer from the liquid lubricant to the coolant. The gear set can include more than one shaft, with at least one gear configured to splash oil onto the cooling pins to transfer heat from the liquid lubricant to a coolant flowing in a motor housing adjacent the first region.

In a drive device, a first flow path of a fluid connects a gear accommodation portion and an inlet of a pump. A second flow path connects an outlet of the pump and one end of a third flow path via a cooler. The third flow path is inside a partition wall of a housing and intersects a rotation axis of a first shaft. A fourth flow path connects another end of the third flow path and one end of a fifth flow path. The fifth flow path is inside a gear side lid of the housing. Another end of the fifth flow path is connected to one end of a second shaft in an axial direction. One end of a sixth flow path is connected to another end of the third flow path. Another end of the sixth flow path is inside a housing tubular portion.

A fluid delivery system for supplying fluid to at least one machine assembly, in particular an engine and/or transmission of a motor vehicle, including: a first pump and a second pump; a drive for driving the first pump and/or the second pump; a reservoir for storing the fluid; and a filter module for filtering the fluid, wherein the first pump delivers fluid from the reservoir to the machine assembly in a supply flow and the second pump is arranged downstream of the machine assembly and delivers at least some of the fluid into the reservoir in a sub-flow downstream of the machine assembly and the filter module is embodied in the sub-flow.

A fluid delivery system for supplying fluid to a machine assembly includes: a pump module; a drive for the pump module; and a housing which includes a reservoir for the fluid. The reservoir includes an aspiration point, and the pump module includes a first inlet, a second inlet, a first outlet and a second outlet. The first inlet is fluidically connected to the reservoir via a first suction conduit, and the first outlet is fluidically connected to the machine assembly via a first pressure conduit. The second inlet is fluidically connected to the housing via a second suction conduit, and the second outlet is fluidically connected to the reservoir via a second pressure conduit.

An oil cooler for cooling an oil with a cooling water, the oil being for lubricating a transaxle in a state of being attached to the case for accommodating the transaxle, includes: an oil inlet opening on a mounting surface attached to the case; an oil outlet opening on the mounting surface; a first opening, which is an opening on the mounting surface, for cooling water; and a second opening, which is an opening on a portion other than the mounting surface, for cooling water. Further, a heat exchange is performed between the oil flowing through an oil passage connecting the oil inlet and the oil outlet and the cooling water flowing through a water passage connecting the first opening and the second opening.
