Japanese Patent JP6834879
Kind Code:
B2
Abstract:
To enhance the lubrication performance of a pinion gear even in the case of disposing a lubrication hole so as to be suitable to lubrication in a specific travel mode.SOLUTION: In a first reverse travel mode (U/DHV mode forward rotation input (reverse), O/DHV mode forward rotation input (reverse)) where a third lubricant oath 88 is positioned downstream in an auto-rotation direction of a pinion gear P2 relative to a load region, a lubricant volume supplied from a hydraulic control circuit 60 is increased in comparison with a second reverse travels mode (U/DHV mode reverse rotation input (reverse) where the third lubricant oath 88 is positioned upstream in the auto-rotation of the second pinion gear P2 relative to the load region likewise the forward travel mode, and therefore the lubricant ejected from the third lubricant oath 88 easily reaches the entire load region even in the first reverse travel mode that is disadvantageous to the lubrication. This makes it possible to enhance lubrication performance of the second pinion gear P2 even in the case of disposing the third lubricant oath 88 so as to be suitable to the lubrication in the forward travel mode.SELECTED DRAWING: Figure 26
