Description

Vehicle axle shaft unit.

The present invention relates to an axle shaft unit for a vehicle. More specifically, a C / V joint or a C / V joint or a C / G joint and a joint boot when repairing or disassembling a joint boot, It relates to an axle shaft unit for a vehicle in which the C / G joint and the boot are firmly mounted to prevent oil from leaking.

In general, the vehicle is provided with an axle shaft unit to transfer the power of the engine to the wheel to drive the car.

A perspective view showing such a general axle shaft unit and an installation state is shown in FIG. 1, and FIG. 2 is a cross-sectional view showing the structure of the axle shaft unit.

According to FIGS. 1 and 2, for example, the front axle shaft unit basically includes an axle shaft 1, and one end of the axle shaft 1 is equipped with a C / V joint 2, and the other end thereof. The C / G joint 3 is mounted. A joint boot is used when the C / V joint and the C / G joint 3 are mounted on the axle shaft 1, for example, when the axle shaft 1 and the C / V joint 2 are mounted. The boot 4 is applied and the joint boot 5 is applied when the axle shaft 1 and the C / G joint 3 are mounted. The reason why the joint boots 4 and 5 are applied in this way is to include oil for smooth linkage between the joints 2 and 3 of the axle shaft 1.

In addition, clamps 6 and 7 are generally used for mounting each of the joints 2 and 3 and the respective joint boots 4 and 5 to each other. That is, after mounting the C / V joint 2 and the joint boot 4 and tightening it with the clamp 6, the clamp 7 is firmly mounted and the clamp 7 after the C / G joint 3 and the joint boot 5 are mounted. It is firmly mounted by using.

However, even when the joints 2 and 3 and the joint boots 4 and 5 are firmly clamped by using the respective clamps 6 and 7 as described above, the respective joint boots 4 and 5 and the Since the mutual mounting surfaces of the respective joints 2, 3 are formed flat, respectively, the joint boots 4, 5 can be rotated with respect to the joints 2, 3 and thus with the respective joints 2, 3 There was a problem in that oil leaked through the interface of the joint boots 4 and 5.

Therefore, the present invention has been devised to solve such a problem, and an object of the present invention is to provide an axle shaft unit for a vehicle in which the joint boot is prevented from rotating relative to the C / V joint and the C / G joint.

Another object of the present invention is to provide an axle shaft unit for a vehicle in which leakage of oil is prevented through a mounting surface between the C / V joint and the joint boot and the C / G joint and the joint boot.

These objects are achieved by a preferred embodiment of the present invention, according to one aspect of the present invention, an axle shaft, a C / V joint mounted to one end of the axle shaft, C / mounted to the other end of the axle shaft A vehicle axle shaft comprising a joint butt mounted to the G joint, the C / V joint and the axle shaft and containing oil, and a joint boot to the C / G joint and the axle shaft and containing oil, A plurality of protrusions are formed on the mounting surface of the C / V joint to which the joint boot is mounted at predetermined intervals, and an accommodating groove corresponding to the plurality of protrusions is formed on the inner fastening surface of the joint boot, and the joint boot is mounted. A plurality of protrusions are formed on the mounting surface of the C / G joint at a predetermined interval, and the receiving groove corresponding to the plurality of protrusions is provided on the inner fastening piece of the joint boot. It is formed, characterized in that the protrusion of each of the joints and the receiving groove of each of the joint boot is engaged with each other.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a perspective view of the axle shaft unit according to the present invention, Figure 4 is a cross-sectional view showing the mounting structure of the axle shaft unit according to the present invention.

3 and 4, the axle shaft unit 10 according to the present invention basically includes an axle shaft 11 as described above, and one end of the axle shaft 11 has a C / V joint 12. ) Is mounted and the other end is equipped with a C / G joint (13). In addition, the joint boot 14 is fastened to the C / V joint 12 by the clamp 16, and the joint boot 15 is fastened to the C / G joint 12 by the clamp 17.

Reference numerals 18a and 18b are clamps and 19a and 19b are shaft snaprings.

Particularly, each mounting method in which the C / V joint 12 and the joint boot 14 are mounted according to the present invention is arranged along a predetermined interval, that is, on the mounting surface 12a on one side of the C / V joint 12. The protrusions 20 are formed at regular intervals, and a plurality of grooves 21 corresponding to the plurality of protrusions 20 are formed at predetermined intervals on the inner contact surface 14a of the joint boot 14 to each other. It is attached.

Each mounting method in which the C / G joint 13 and the joint boot 15 are mounted is also formed in an uneven form along a predetermined interval, and the mounting surface 13a of the C / G joint 13 A plurality of protrusions 22 are formed, and a plurality of grooves 23 are formed on the inner contact surface 15a of the joint boot 15 to be interlocked with each other. In this way, the clamp 16 is fastened while the C / V joint 12 and the joint boot 14 are mounted, and the clamp 17 is mounted while the C / G joint 13 and the joint boot 15 are mounted. Then the installation is completed.

In this way, when the C / V joint 12 and the C / G joint 13 and the joint boots 14 and 15 are mounted on the axle shaft 11, the mounting surface 12a of each of the joints 12 and 13 is mounted. Interlocking between the plurality of protrusions 20, 22 formed in the 13a and the plurality of grooves 21, 23 formed in the fastening surfaces 14a, 15a of the joint boots 14, 15 and the respective clamps 16, They are firmly joined together by the clamping force of 17). Accordingly, rotation of the respective joint boots 14 and 15 with respect to the respective joints 12 and 13 is prevented, and there is no gap between the occlusal surfaces, so that oil inside each boot 14 and 15 leaks. Is prevented.

As a result, when the axle shaft unit according to the present invention is applied to a vehicle, even if the C / V joint or the C / G joint and the respective joint boots are frequently repaired, disassembled, and replaced, the concave-convex joints are executed instead of the mutual contact. In addition to preventing rotation between each other, accordingly, leakage of oil in the boot is prevented, thereby improving product quality and preventing performance deterioration.

Although a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and variations can be made without departing from the scope of the appended claims.
