Abstract

A hydraulic tube for a vehicle may include a pipe having a pipe rib which may be formed integrally on and protrudes outward from a terminal end of the pipe, a connector fitted around the pipe such that the pipe extends through opposite ends of the connector, and a sealer fitted into a first end of the connector, a first end of the sealer being coupled with the terminal end of the pipe through coupling with the pipe rib, and a second end of the sealer being coupled with the first end of the connector.

First claim

What is claimed is:

1. A hydraulic tube for a vehicle comprising:
a pipe having a pipe rib which is formed integrally on and protruded outward in a radial direction of the pipe from an end of the pipe;
a connector fitted around the pipe such that the pipe extends through opposite ends of the connector; and
a sealer fitted into a first end of the connector, a first end of the sealer being coupled with the end of the pipe through coupling with the pipe rib, and a second end of the sealer being coupled with the first end of the connector,
wherein the sealer comprises:
a sealer hole extending through opposite ends of the sealer, a first end of the pipe being to be fitted into the sealer through the sealer hole; and
a first sealer groove at a first end of the sealer hole, the pipe rib being fitted into and coupled with the first sealer groove,

wherein the first sealer groove comprises:
an inclined surface which is to be in face contact with the pipe rib;
an extension surface extending from a terminal of the inclined surface toward the second end of the sealer so as to be parallel with the sealer hole;
a perpendicular surface connected to the sealer hole perpendicularly from a terminal of the extension surface; and
an enclosed space which is closely defined by the pipe rib, the extension surface; and the perpendicular surface in order to improve a performance of sealing between the pipe and the sealer and an oil leakage prevention effect.

2. The hydraulic tube according to claim 1 , wherein the connector has a connector hole extending through the opposite ends of the connector, the pipe being fitted into the connector hole, wherein a diameter of the connector hole from a first end to a second end of the connector hole is equal.

3. The hydraulic tube according to claim 2 , wherein, in a section of the connector hole from the first end to the second end of the connector hole, no portion of the connector hole is connected to outside of the connector except for the opposite ends that are opened.

4. The hydraulic tube according to claim 2 , wherein portions of the connector hole from the first end to the second end of the connector hole adjoin to an outer circumference of the pipe.

5. The hydraulic tube according to claim 1 , wherein the connector comprises a continuous connector rib and a continuous connector groove to couple with the sealer on outer circumferences of the first end thereof which is disposed in a direction toward the pipe rib.

6. The hydraulic tube according to claim 1 ,
wherein the first end of the connector in which the connector rib and the connector groove are formed is configured so as to be fitted into the second end of the sealer hole, and
wherein a continuous second sealer groove and a continuous inner rib are formed on the second end of the sealer hole, the second sealer groove being fitted around and coupled with the connector rib, and the continuous inner rib being fitted into and coupled with the connector groove.

7. The hydraulic tube according to claim 1 , wherein the pipe is made of steel, the connector is made of plastic, and the sealer is made of rubber.
