Abstract
Provided is a device that includes a transfer input gear meshing with a final driven gear, a transfer input shaft pivotally supporting the transfer input gear, a first bevel gear provided on the transfer input shaft, a second bevel gear meshing with the first bevel gear, a transfer output shaft pivotally supporting the second bevel gear, a transfer case covering at least the first bevel gear and the second bevel gear, and a guide section guiding at least part of scooped fluid that is scooped up by the final driven gear into the transfer case.
Claims15
A power transmission device comprising a transfer device, the transfer device including:
- a transfer input gear meshing with a final driven gear or another gear rotating integrally with the final driven gear;
- a transfer input shaft pivotally supporting the transfer input gear;
- a first bevel gear provided on the transfer input shaft;
- a second bevel gear meshing with the first bevel gear;
- a transfer output shaft pivotally supporting the second bevel gear;
- a transfer case covering at least the first bevel gear and the second bevel gear;
- and
- a guide section guiding at least part of scooped fluid that is scooped up by the final driven gear into the transfer case, wherein
- the transfer input gear meshes with the final driven gear or the another gear above a rotation center of the final driven gear,
- a direction of rotation of the transfer input gear or the another gear and the final driven gear is a direction in which a portion of meshing engagement with each other rotates upward,
- a transmission case is included that is configured to accommodate the final driven gear or the another gear and the transfer input gear,
- the scooped fluid is part of lubricating oil accumulated at a bottom of the transmission case wherein a lower end of the final driven gear is immersed in the lubricating oil,
- the final driven gear meshing with a final drive gear;
- and
- the transmission case rotatably supporting the final driven gear via a bearing, wherein
- the transmission case includes a recessed section that is recessed toward the transfer device in a direction corresponding to a central axis about which the final driven gear rotates, the recessed section corresponding to a portion where the final driven gear or another gear rotating integrally with the final driven gear meshes with the transfer input gear, and
- the guide section is positioned on a front side in a direction of rotation of the final driven gear or the another gear or the transfer input gear relative to a portion where the final driven gear or the another gear and the transfer input gear mesh with each other.
