Abstract: An exemplary transmission may have a reverse shift rail and a locking mechanism to ensure that the reverse shift rail stops in a neutral position when disengaging from the other gear range. The reverse shift rail may be configured to move axially in a first direction to place the transmission in a drive gear, and in a second direction for a reverse gear. The transmission may also include a rail selector configured to engage with the reverse shift rail, and a reverse inhibitor configured to selectively dampen the reverse shift rail from moving in the second direction. An exemplary locking mechanism may include a main body and an arm extending from the main body. When the reverse shift rail disengages from the drive gear, the arm may be configured to contact the reverse inhibitor to substantially inhibit the movement of the reverse shift rail in the second direction.

Abstract translation: 示例性变速器可以具有倒档换档轨道和锁定机构，以确保当与另一档位分离时，反向换档导轨停止在中立位置。 反向换档导轨可以被构造成沿第一方向轴向移动，以将变速器放置在驱动齿轮中，并且在第二方向上用于倒档。 变速器还可以包括配置成与倒档轨道接合的轨道选择器，以及反向抑制器，该反向抑制器被配置为选择性地阻尼反向换档轨道沿第二方向移动。 示例性的锁定机构可以包括主体和从主体延伸的臂。 当反向换档导轨与驱动齿轮脱离啮合时，臂可构造成接触反向阻尼器以基本上禁止反向换档导轨沿第二方向的移动。
