Abstract(J)A/Tのクラッチ開放時における引き摺りトルクを低減することで燃費向上が可能である。トルクを低減するには板間距離を大きくすることが有効であるが、板開距離は多板間の油流れの相対関係で変動する為に複雑であり検討事例が少ない。今回、板間の圧力による板間距離変動とそれによる引き摺りトルク変動を定量化できるモデルを構築したので報告する。

Abstract(E)Fuel efficiency of vehicle can be improved by reducing the drag torque when the A/T clutch is disengaged. To increase the distance between the plates can reduce the drag torque, but the plate distance is a complicated phenomenon that depend on the relationship of the oil flow between multiple plates. Due to its complexity, there are few cases of studying the distance between plates. In this report, we study the fluctuation of the plate distance and drag torque, due to the pressure between the plates, and create a mathematical model of this phenomenon.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
