Abstract

A gear-shifting device for a vehicle is provided and includes a guide body that has a first end portion connected to a control shaft, installed so that a second end portion is rotated at the first end portion as an axis in a rotational displacement that corresponds to a selecting path to perform a selecting operation, and installed to be moved in a substantially straight displacement that corresponds to a shifting path along an axis direction of the first end portion to perform a shifting operation. A guide unit is disposed to distinguish each shifting path on the selecting path in which the second end portion of the guide body is rotated and is configured to guide the second end portion of the guide body to be movable along the shifting path.

First claim

What is claimed is:

1. A gear-shifting device for a vehicle, the gear-shifting device comprising:
a guide body having a first end portion connected to a control shaft, installed so that a second end portion of the guide body is rotated at the first end portion as an axis in a rotational displacement that corresponds to a selecting path to perform a selecting operation, and installed to be moved in a substantially straight displacement corresponding to a shifting path along an axis direction of the first end portion to perform a shifting operation;
a guide unit disposed to distinguish each shifting path on the selecting path in which the second end portion of the guide body is rotated and configured to guide the second portion of the guide body to be movable along the shifting path; and
a stopper unit having a stopper plate rotatably disposed at an end portion position of the selecting path in which the second end portion of the guide body is rotated,
wherein the stopper plate is configured to block the second end portion of the guide body from being positioned at the selecting path connected to an uppermost shifting path when the guide body rotates along the selected path, and
wherein when the guide body is moved to a lower shifting path disposed at one side of the uppermost shifting path to perform the shifting operation, and is then rotated and moved toward the selecting path connected to the uppermost shifting path, the stopper plate is caught by the guide body to be rotated together with the guide body and is configured to position the second end portion of the guide body at the selecting path connected to the uppermost shifting path, and the second end portion of the guide body is moved to the uppermost shifting path to perform the shifting operation.

2. The gear-shifting device of claim 1 , wherein the guide body has a path guiding groove formed at a substantial center of the second end portion and shifting parts are formed at both ends of the path guiding groove.

3. The gear-shifting device of claim 2 , wherein the guide unit includes:
a guide plate installed at the second end portion side of the guide body; and
a guide protrusion and a guide groove alternately disposed at an end portion of the guide plate along a rotating path of the second end portion of the guide body,
wherein upon rotating the guide body, the guide protrusion or the guide groove is positioned in the path guiding groove of the guide body.

4. The gear-shifting device of claim 3 , wherein both sides of an inner end of the shifting part and both sides of an outer end of the guide protrusion include a plurality of chamfers having a gradient that corresponds to each other upon contact.

5. The gear-shifting device of claim 1 , wherein the stopper unit includes:
a stopper guide formed protruding at an intermediate end of the guide body;
a supporting plate disposed at an end portion of the rotating path in which the stopper guide is rotated; and
a stopper plate rotatably coupled to a shaft of the supporting plate and having a stopper protrusion formed to be protruded at an end portion toward the stopper,
wherein the stopper protrusion is formed at a position at which the stopper guide is caught when the second end portion of the guide body is positioned in the lower shifting path disposed to one side of the uppermost shifting path.

6. The gear-shifting device of claim 5 , further comprising:
a return spring provided around the shaft and having both end portions supported by the stopper plate and the supporting plate, respectively, to provide elastic restoring force to the stopper plate when the stopper plate is rotated.

7. The gear-shifting device of claim 6 , wherein supporting protrusions are formed on outer surfaces of the stopper plate and the supporting plate, the return spring is inserted into a pin member axially coupling the stopper plate and the supporting plate, and the respective supporting protrusions elastically support both ends of the return spring.

8. The gear-shifting device of claim 5 , wherein catching grooves are formed to be depressed at both sides of the stopper protrusion, and return protrusions are formed protruding at side portions of the catching grooves.

9. The gear-shifting device of claim 5 , wherein a seating groove is formed in a concave shape at an intermediate end of the stopper protrusion to cause the stopper guide to be caught.

10. The gear-shifting device of claim 5 , wherein the supporting plate and the guide plate are integrally formed.

11. A gear-shifting device for a vehicle performing a gear-shifting operation based on a manual gear-shifting gate having a plurality of gear-shifting levels disposed one by one in a plurality of substantially straight passages vertically connected to one side or both sides along a neutral line and a diagonal passage diagonally formed from an end portion of the neutral line connected to an outermost substantially straight passage to an intermediate end of a lower substantially straight passage provided to one side of the outermost substantially straight passage, the gear-shifting device comprising:
a guide body having a first end portion connected to a control shaft, installed so that a second end portion is rotated at the first end portion as an axis in a rotational displacement that corresponds to a selecting path to perform a selecting operation along the neutral line and the diagonal passage of the manual gear-shifting gate, and installed to be moved in a substantially straight displacement that corresponds to a shifting path along an axis direction of the first end portion to perform a shifting operation along the straight passage;
a guide unit disposed to distinguish each shifting path on the selecting path in which the second end portion of the guide body is rotated and is configured to guide the second end portion of the guide body to be movable along the shifting path; and
a stopper unit having a stopper plate rotatably disposed at an end portion position of the selecting path in which the second end portion of the guide body is rotated,
wherein the stopper plate is configured to block the second end portion of the guide body from being positioned at the selecting path connected to an outermost substantially straight passage when the guide body rotates along the selecting path, and
wherein when the guide body performs a shifting operation to a gear-shifting level that corresponds to a substantially lower straight passage, and is then rotated and moved toward the selecting path connected to the outermost substantially straight passage, the stopper plate is rotated to allow a gear-shifting level disposed at the outermost substantially straight passage to be shifted.
