Locking mechanism for a reverse shift rail of a transmission

摘要

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.

主权项

1. A transmission, comprising:
a reverse shift rail of a transmission configured to move axially in a first direction from a neutral position to activate a drive gear range, and in a second direction from the neutral position to activate a reverse gear range; a main shaft rail aligned substantially parallel to the reverse shift rail and configured to move in an axial direction and to rotate about an axis; a rail selector on the main shaft rail and having a wing 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; and a locking mechanism comprising:
a main body positionable and operatively rotatable around at least a portion of the reverse shift rail, andan arm extending from the main body, the arm being configured to engage with the wing to enable the main body to rotate from a first position,wherein the arm is configured to come into contact with the reverse inhibitor when the reverse shift rail disengages from the drive gear range to the neutral position.
