LUBRICATION STRUCTURE FOR VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17940212 titled 'LUBRICATION STRUCTURE FOR VEHICLE

Simplified Explanation

The abstract describes a lubrication structure for a vehicle that includes two lubrication pipes and an oil pump. The structure also includes two oil holes in the case, with one connected to the first lubrication pipe and the other receiving lubricating oil from the second lubrication pipe. The connection between the first lubrication pipe and the first oil hole is positioned above the opening of the second oil hole, allowing some of the lubricating oil to flow into the second oil hole.

  • The lubrication structure is designed for vehicles with rotary machines and bearing members.
  • It includes a first lubrication pipe for supplying oil to the rotary machine and a second lubrication pipe for supplying oil to the bearing member.
  • An oil pump is used to supply lubricating oil to both pipes.
  • The structure features a first oil hole connected to the first lubrication pipe and a second oil hole receiving oil from the second lubrication pipe.
  • The connection between the first lubrication pipe and the first oil hole is positioned above the opening of the second oil hole, allowing some oil to flow into the second oil hole.

Potential Applications

  • This lubrication structure can be applied in various vehicles, such as cars, trucks, motorcycles, and other machinery with rotary machines and bearing members.

Problems Solved

  • The lubrication structure ensures proper lubrication of both the rotary machine and the bearing member, enhancing their performance and longevity.
  • By allowing some of the lubricating oil to flow into the second oil hole, the structure improves the overall lubrication efficiency.

Benefits

  • Improved lubrication of the rotary machine and bearing member leads to reduced friction, wear, and heat generation.
  • The structure helps prevent damage and failure of the rotary machine and bearing member, increasing their lifespan.
  • Enhanced lubrication efficiency contributes to better overall vehicle performance and fuel efficiency.


Original Abstract Submitted

A lubrication structure for a vehicle includes: a first lubrication pipe through which lubricating oil is supplied to a rotary machine disposed in a case; a second lubrication pipe through which lubricating oil is supplied to a bearing member disposed in the case; and an oil pump that supplies lubricating oil to the first and second lubrication pipes. The lubrication structure includes a first oil hole in the case that is connected to the first oil hole, and a second oil hole in the case, lubricating oil flowing into the second oil hole from the second lubrication pipe. A connection portion between the first lubrication pipe and the first oil hole is located above an opening portion of the second oil hole such that at least a part of lubricating oil that has flowed out from the connection portion flows into the second oil hole.
