Heat exchanger apparatus for lubricating oil in power transmission
The patent US12044303B2 describes an innovative apparatus designed to enhance the efficiency of power transmission systems through a specialized heat exchanger and lubrication mechanism. The apparatus features a heat exchanger, a power transmission mechanism that connects a drive source to drive wheels, and a lubricating oil passage that directs oil downstream from the heat exchanger to the power transmission mechanism. Additionally, it includes a drain oil passage that facilitates the removal of lubricating oil between the heat exchanger and the power transmission mechanism. A notable design aspect is the wall that separates the power transmission mechanism from a member devoid of exposed rotary elements, with the drain oil passage directing oil to the back face of this wall.
Further detailing the apparatus, the claims specify that the drain oil passage consists of a main portion and a throttle portion, the latter having a reduced flow path area compared to the main portion. The throttle portion is designed to be shorter than the main portion, and both passages can be integrated into a plate structure. The design allows for the throttle portion to open onto the surface of the plate, and the main and throttle portions may intersect, optimizing the flow of lubricating oil. This configuration aims to improve the overall performance and reliability of the power transmission system by ensuring effective lubrication and heat management.
