Abstract
Description
以下、本発明の実施形態について図面を参照しながら説明する。図1は、本発明の第1実施形態に係るねじり試験装置100の側面図である。本実施形態のねじり試験装置100は、2つの回転軸を有する供試体T1(例えばFR車用トランスミッションユニット)の回転ねじり試験を行う装置である。すなわち、ねじり試験装置100は、供試体T1の2つの回転軸を同期回転させながら2つの回転軸の回転に位相差を与えることで、トルクを負荷しながら供試体T1の2つの回転軸を回転させる。本実施形態のねじり試験装置100は、第1駆動部110、第2駆動部120、及びねじり試験装置100の動作を統合的に制御するコントローラCを備えている。
図3は、本発明の第2実施形態に係るねじり試験装置200の平面図である。上述のように、本実施形態は、FF車用のトランスミッションユニットを供試体T2とする回転ねじり試験に適したねじり試験装置の構成例である。供試体T2は、ディファレンシャルギアを内蔵するトランスミッションユニットであり、入力軸Iと、左側出力軸OL及び右側出力軸ORを有している。
次に、本発明の第3実施形態について説明する。図4は、本発明の第3実施形態に係るねじり試験装置300の平面図である。本実施形態は、FR車用のディファレンシャルギアユニットを供試体T3とする回転ねじり試験に適したねじり試験装置の構成例である。第2の実施形態と同様に、供試体T3は、入力軸I、左側出力軸OL及び右側出力軸ORを有している。
図5は、本発明の第4実施形態に係るねじり試験装置400の平面図である。本実施形態のねじり試験装置400は、4つの回転軸を有する供試体T4の回転ねじり試験に適したねじり試験装置の構成例である。以下、一例として、4WDシステムを供試体T4として試験を行う場合について説明する。供試体T4は、図示しないトランスミッション、フロントディファレンシャルギア、トランスファー及び電子制御多板クラッチを備えたFFベースの電子制御式4WDシステムである。供試体T4は、エンジンに接続される入力軸Iと、左右の前輪用のドライブシャフトに接続される左側出力軸OL及び右側出力軸ORと、後輪に動力を伝達するプロペラシャフトに接続される後部出力軸OPを有している。入力軸Iから供試体T4に入力された駆動力は、供試体T4に備わるトランスミッションにより減速された後、フロントディファレンシャルギアを介して、左側出力軸OLと右側出力軸ORに分配される。また、フロントディファレンシャルギアに伝達された駆動力の一部は、トランスファーにより分岐されて、後部出力軸OPから出力されるように構成されている。
