Description

【考案の詳細な説明】 この考案は既存の変速段用歯車をオイルポンプとして構
成した歯車変速機用オイルポンプに関するものである。[Detailed Description of the Invention] This invention relates to an oil pump for a gear transmission, which is configured using an existing gear for gears as an oil pump.

従来、歯車変速機においては、アイドリング時における
エンジン出力軸のトルク変動により、被駆動歯車がバツ
クラッシ分だけ遊動して駆動歯車と打合って歯打音が発
生した。Conventionally, in gear transmissions, due to torque fluctuations of the engine output shaft during idling, the driven gear moves by the amount of backlash and collides with the drive gear, resulting in rattling noise.

く、しかもコストが高くなる欠点があった。As a solution to this problem, a method is known in which a separate oil pump is connected to the countershaft to which the driven gear is fixed to provide rotational resistance, thereby suppressing the free movement of the driven gear. Since the oil pump is a so-called independent component of the transmission, it has the disadvantage of being heavy and costly.
