{INSULATOR TEMPORARILY FIXED STRUCTURE OF SHOCK ABSORBER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a temporary fixing structure for an insulator of a shock absorber, and more particularly, to a temporary fixing structure for an insulator of a shock absorber, which comprises a polygonal coupling projection and a temporary fixing cap, The present invention relates to a temporary fixing structure of a shock absorber for a shock absorber which can improve workability because the alignment state is not changed, and there is no separate correction procedure, thereby reducing the work flow.

Generally, the shock absorber acts to suppress or attenuate vibration from the road surface, and absorbs the vibration energy of the vehicle body in the vertical direction while being mounted between the vehicle body or the frame and the wheel.

In addition, the shock absorber can reduce the dynamic stress at the corner of the vehicle body to increase the durability life, suppress the movement of the mass under the spring to secure the grounding property of the tire, suppress the attitude change due to the inertia force, .

In such a shock absorber, an upper end of the piston rod is usually fixed to the vehicle body side, and a lower end of the cylinder is fixed to the wheel side. To this end, an insulator (also referred to as a top mount) is provided at an upper end of the piston rod.

Here, the insulator is coupled to the vehicle body side by a fastening member such as a bolt, and at least one fastening hole is formed to engage the fastening member.

Among these, the insulator with single type bearing in the DSM (Damper Spring Module) of McPherson strut which is one of the front suspension type has the structure of free rotation.

In such an insulator, it is necessary to accurately align the directions of three points at which the upper shock tower and the fastening member are assembled when assembling the vehicle, but the alignment is difficult due to the rotation of the insulator, , And the workability was lowered, which contributed to an increase in cost and airflow.

A prior art related to the present invention is Korean Patent No. 10-2009-0034118 (Apr. 07, 2009), which discloses an integrated insulator type strut assy of suspensions.

An object of the present invention is to combine the engaging projections of a polygonal shape and the provisional fixed caps forming the corresponding engaging grooves to fix the insulator in the installation work on the vehicle so that the alignment state is not changed and workability can be improved And to provide a temporary fixing structure of a shock absorber insulator which can reduce the work flow without a separate correction procedure.

A temporary fixing structure for an insulator of a shock absorber according to the present invention comprises a coupling protrusion formed on an upper end of a piston rod extending from a cylinder and a coupling protrusion coupled to an upper portion of the cylinder, And a temporary fixing cap which is inserted into the through hole and is coupled to the coupling groove at the lower end so as to support the insulator at an upper portion thereof.

Here, it is preferable that the side surfaces of the engaging projections and the inner surfaces of the engaging grooves are formed with corresponding bent portions.

Preferably, a handle is protruded from the upper end of the temporary fixing cap.

The temporary fixing cap may include a first coupling hole protruding downward and coupled to the through hole, a second coupling hole formed in the inner space of the first coupling hole so as to be spaced apart from the inner space of the first coupling hole, And an engaging step protruding from the side portion and being engaged with an upper end of the through hole.

In addition, it is preferable that the first coupling hole is further formed with a cut-out groove so as to be shrunk when inserted into the through hole.

It is also preferable that the insulator is coupled to the vehicle by a fastening member, and the temporary fixing cap is separated from the through hole and the engaging projection after engaging the insulator with the vehicle.

In addition, it is preferable that a finishing cap is further coupled to the through hole after the temporary fixing cap is detached.

The present invention combines a polygonal coupling projection and a provisional fixing cap forming a coupling groove corresponding thereto to fixedly position the insulator at the time of installation in a vehicle so that the alignment state is not changed and workability can be improved, There is an effect that the work flow can be reduced.

1 to 5, a temporary fixing structure for an insulator of a shock absorber according to the present invention includes a cylinder 10, a piston rod 20, and a piston valve 30.

Particularly, the temporary fixing structure of the insulator of the shock absorber according to the present invention includes the coupling protrusion 100, the insulator 200, and the temporary fixing cap 300.

First, the cylinder 10 may have a cylindrical shape that forms a space therein, and a fluid (oil or the like) is filled in the inner space of the cylinder 10.

One end of the cylinder 10 and one end of the piston rod 20, which will be described later, can perform compression and tensile strokes while being connected to the vehicle body side or the wheel side, respectively.

Further, at the lower end of the cylinder 10, a separate coupling portion (not shown) for connecting to the vehicle body side or the wheel side can be provided.

The piston rod 20 is coupled to a piston valve (not shown) provided at one end inside the cylinder 10 and the other end of the piston rod 20 extends to the outside of the cylinder 10, And is connected to the wheel side.

The piston valve divides the inside of the cylinder 10 into a compression chamber and a tension chamber. The piston valve reciprocates in the compression and tensile directions inside the cylinder 10 to generate a damping force due to the resistance force of the fluid.

The engaging projection 100 is formed at the upper end of the piston rod 20 extending from the inside of the cylinder 10 and the engaging projection 100 is inserted through the through hole 210 to be described later.

The bending part 110 is formed on the side surface of the coupling protrusion 100 so that the temporary fixing cap 300, which will be described later, is not rotated in the horizontal direction.

At this time, mutually parallel horizontal surfaces may be formed on both sides of the coupling protrusion 100, and mutually corresponding curved surfaces may protrude from the horizontal surfaces.

The insulator 200 is fixedly attached to the vehicle by a fastening member 230 while being coupled to the upper portion of the cylinder 10. [

Here, the insulator 200 may be formed with a fastening hole 220 through which the fastening member 230 is coupled.

As shown in FIG. 4, the insulator 200 is formed with through holes 210 so that the upper ends of the piston rods 20 are positioned inside.

The through hole 210 has a shape corresponding to the side surface of the temporary fixing cap 300. The temporary fixing cap 300 is inserted into the through hole 210 in a corresponding manner.

The temporary fixing cap 300 inserted into the through hole 210 may be fixed by a press fitting method. At this time, the temporary fixing cap 300 is coupled to be rotatable in the horizontal direction, Do not.

For this purpose, the inner circumferential surface of the through-hole 210 and the side surface of the temporary fixing cap 300 may be formed with a locking groove or a locking protrusion so as to be engaged with each other.

In addition, the through hole 210 and the temporary fixing cap 300 may have a cylindrical shape so as to be horizontally rotatable in a coupled state.

The temporary fixing cap 300 is inserted in the through hole 210 and supports the insulator 200 from above.

The temporary fixing cap 300 is press-fitted into the through hole 210 so that the lower end of the temporary fixing cap 300 is in a shape corresponding to the through hole 210 of the insulator cap 200 .

Here, a coupling groove 321 is formed in the lower end of the temporary fixing cap 300 so that the coupling protrusion 100 described above may be coupled to the coupling protrusion 100.

Here, the temporary fixing cap 300 is preferably made of an aluminum material, but the material of the temporary fixing cap 300 can be variously selected.

In more detail, the temporary fixing cap 300 may include a first coupling hole 310, a second coupling hole 320, and a locking hole 330.

The first coupling member 310 protrudes from the lower end of the temporary fixing cap 300 and the first coupling member 310 is coupled to the inside of the through hole 210 in a corresponding manner.

Here, a space portion is formed in the first coupling hole 310 and a space portion of the first coupling hole 310 is opened downward.

The side surface of the first coupling hole 310 is formed to correspond to the inner peripheral surface of the through hole 210 and the first coupling hole 310 is coupled to the through hole 210 in a penetrating manner.

At this time, the first coupling hole 310 is rotatable in the horizontal direction but not in the upper portion.

For this, a locking groove or a locking protrusion may be formed on the side surface of the first coupling hole 310 and the inner peripheral surface of the through hole 210 so as to be engaged with each other.

The first coupling member 310 may have a cylindrical shape so as to be horizontally rotatable in a state of being coupled to the through hole 210.

The lower end of the first coupling hole 310 may be formed with a tapered portion 311 having a gradually smaller diameter.

The tapered portion 311 serves to guide the first coupling hole 310 to the upper entrance portion of the through hole 210 when the first coupling hole 310 is inserted through the upper portion of the through hole 210.

In addition, when the first coupling member 310 is inserted into the through hole 210, a cutout groove 312 is formed so that the cutout can be contracted into the through hole 210.

The cutout groove 312 may be vertically formed such that the first coupling hole 310 can be retracted into the through hole 210 and the lower end of the cutout groove 312 may be opened downward.

The second coupling hole 320 protrudes to the lower portion of the temporary fixing cap 300, and the second coupling hole 320 is positioned in a state of being spaced apart from the space of the first coupling hole 310.

That is, since the second coupling hole 320 and the first coupling hole 310 are spaced apart from each other, the first coupling hole 310 can be contracted in the direction of the through hole 210.

In addition, a coupling groove 321 is formed in the lower portion of the second coupling hole 320 so that the coupling protrusion 100 can be coupled with the coupling protrusion 100 in a press-fitting manner.

A bent portion 321a is formed on the inner circumference of the coupling groove 321 so as to be engaged with the bent portion 110 formed on the side surface of the coupling projection 100.

That is, when the coupling protrusion 100 is inserted into the coupling groove 321, the coupling force between the bending portion 110 of the coupling groove 321 and the bending portion 321a of the coupling protrusion 100 is Can be improved.

Further, mutually parallel horizontal surfaces may be formed on both sides of the coupling groove 321, and curved surfaces corresponding to each other may be formed in a direction perpendicular to the horizontal surfaces.

The hooking end 330 protrudes from the side of the temporary fixing cap 300 and is engaged with the upper end of the through hole 210 when the temporary fixing cap 300 is inserted into the through hole 210.

In addition, a handle 340 is protruded from the upper end of the temporary fixing cap 300 so that an operator can grip the handle 340. The handle 340 can be formed in various shapes.

When the insulator 200 is coupled to the vehicle using the provisional fixed cap 300 of the present invention, the insulator 200 is coupled to the upper portion of the cylinder 10 as shown in FIG. 5, 210 to the temporary fixing cap 300.

At this time, after inserting the coupling protrusion 100 into the coupling groove 321 of the temporary fixing cap 300, the insulator 200 is coupled to the vehicle using the coupling member 230.

In this state, after the temporary fixing cap 300 is separated from the coupling hole 321, the finishing cap 400 may be coupled to the coupling hole 321 to complete the insulator 200 installation process.

As a result, the present invention combines the polygonal coupling projections 100 with the provisional fixing caps 300 forming the coupling grooves 321 corresponding thereto, so that the insulator 200 is fixedly positioned .

As a result, the alignment state is not changed and the workability can be improved, and there is no need for a modification procedure, thereby reducing the work flow.

Although the concrete embodiments of the temporary fixing structure of the insulator of the shock absorber of the present invention have been described above, it is apparent that various modifications are possible within the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.

It is to be understood that the foregoing embodiments are illustrative and not restrictive in all respects and that the scope of the present invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
