Abstract
Official abstract text for this publication.
An apparatus for moving a shift rail of a transmission may include a control shaft provided to be moved in a direction perpendicular to a plurality of shift rails by an actuator, a plurality of rollers protruding from one selected among a corresponding one of the shift rails and the control shaft, the rollers being formed on one of facing sides of the shift rail and the control shaft, and a cam protruding in an S-shaped form from a remaining one selected among the corresponding shift rail and the control shaft, on which no roller is formed, the cam being provided to selectively move the shift rails in an axial direction by moving while coming into contact at opposite sides thereof with the rollers depending on a distance by which the control shaft is moved.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for moving a shift rail of a transmission, the apparatus including: a control shaft provided to be moved in a direction perpendicular to a plurality of shift rails by an actuator; a plurality of rollers protruding from one selected among a corresponding one of the shift rails and the control shaft, the rollers being formed on one of facing sides of the shift rail and the control shaft; and a cam protruding in an S-shaped form from a remaining one selected among the corresponding shift rail and the control shaft, on which no roller is formed, the cam being provided to selectively move the shift rails in an axial direction by moving while coming into contact at opposite sides thereof with the rollers depending on a distance by which the control shaft is moved, wherein the rollers are arranged side by side in a radial direction on the control shaft, and wherein the cam is formed in the S-shaped form in the radial direction on each of the shift rails, and is provided to allow the rollers to surround and pass the cam, while the control shaft is moved.
