Description

[0001] SHOCK ABSORBER HOUSING FOR VEHICLE [0002]

An embodiment of the present invention relates to a vehicle shock absorber mounting structure, and more particularly, to a vehicle shock absorber housing for mounting a shock absorber on a vehicle body.

 Background Art [0002] Generally, a shock absorber in a vehicle is a component of a suspension device, and plays a role of absorbing vibration inputted from a road surface during driving of the vehicle to improve ride comfort.

In the shock absorber, the lower end portion is connected to the front wheel and the rear wheel of the vehicle, respectively, and the upper end portion is fixedly mounted on the vehicle body to effectively cancel the vibration input from the front wheel and the rear wheel during running of the vehicle, and to distribute the residual load to the vehicle body.

Here, the shock absorber connected to the front wheel of the vehicle is bolted to the shock absorber housing mounted on the upper portion of the wheel housing of the vehicle and connected to the vehicle body.

The conventional shock absorber as described above is structured to be connected to a vehicle body through a shock absorber mounting unit including a shock absorber housing and a tapping nut mounted on the shock absorber housing.

In the prior art, the shock absorber housing is made of steel or aluminum. The steel shock absorber housing can be manufactured by press molding several parts and assembling them by spot welding.

The aluminum shock absorber housing is advantageous in terms of weight saving compared with steel materials, and is highly advantageous in terms of material cost and formability. It is a casting method capable of complicated shape and large depth molding, and is manufactured by aluminum high vacuum die casting method.

However, the steel-made shock absorber housing is heavy in weight and has a large number of single parts, so that there is a disadvantage that a separate welding process is required for assembly. In addition, the shock absorber housing made of aluminum is produced by die casting method in which aluminum is injected into the die, which is a casting mold, in the form of molten metal, so that it can be manufactured as a single unit with light weight, There are disadvantages in terms of productivity due to a large number of processes.

The matters described in the above background section are intended to enhance understanding of the background of the invention and may include matters not previously known to those having ordinary skill in the art to which the present invention belongs.

Embodiments of the present invention are to provide a vehicle shock absorber housing which is press-molded by using a tailor rolled blank (TRB) aluminum plate material having a different thickness for each part.

A vehicle shock absorber housing according to an embodiment of the present invention is for fixing an upper portion of a shock absorber to a vehicle body. The shock absorber housing is formed of a Tailor Rolled Blank (TRB) aluminum plate material, And a second portion and a third portion located on both sides of the front portion and the rear portion of the first portion, respectively, and the thicknesses of the first, second, and third portions may be different from each other have.

Further, in the vehicle shock absorber housing according to the embodiment of the present invention, the first portion may be formed thicker than the second portion and the third portion.

Further, in the vehicle shock absorber housing according to the embodiment of the present invention, the second portion may be formed to be thinner than the third portion.

Further, in the vehicle shock absorber housing according to the embodiment of the present invention, a reinforcement plate may be further provided on the inner surface of the first portion.

Further, in the vehicle shock absorber housing according to the embodiment of the present invention, the shock absorber housing may be formed by warm molding and blow molding of a tailor roll blank aluminum plate.

Embodiments of the present invention can reduce the weight of the vehicle body because it is a press-warm-molded and blow-molded structure using a tailor rolled blank (TRB) aluminum plate material having a different thickness for each part.

Further, in the embodiment of the present invention, it is possible to improve the vibration performance of the vehicle by increasing the natural frequency while eliminating unnecessary weight increase, and by reducing the maximum stress and the maximum displacement, the rigidity of the shock absorber mounting portion can be increased.

Further, in the embodiment of the present invention, since the tail casting roll blank aluminum plate is manufactured by warm molding and blow molding without applying the high vacuum die casting method, productivity is further improved by reducing the number of manufacturing steps compared to the conventional high vacuum die casting method And cost reduction can be achieved.

FIG. 1 is a perspective view showing a vehicle shock absorber housing according to an embodiment of the present invention, FIG. 2 is a plan view, a bottom view, a front view and a side view of FIG. 1, and FIG.

1 to 3, a vehicle shock absorber housing 100 according to an embodiment of the present invention is for fixing an upper portion of a shock absorber to a vehicle body. The shock absorber housing 100 is provided at an upper portion of a wheel housing of a vehicle body, And one side toward the outside in the width direction of the vehicle can be connected to the side upper member.

The vehicle shock absorber housing 100 according to the embodiment of the present invention is formed by press-molding a tailor roller blank (TRB) aluminum plate material having a different thickness by part.

The vehicle shock absorber housing 100 according to the embodiment of the present invention includes a first portion 10 mounted on a vehicle body and a second portion 10 disposed on both sides of the first portion 10, (20) and a third part (30).

A mounting surface 11 to be mounted on a vehicle body is formed in the first portion 10. A mounting hole 13 is formed in the mounting surface 11 and a plurality of bolt fastening holes 15 and mounting grooves 15 17 are formed.

The shock absorber housing 100 may be press-formed by using a Taylor roll blank aluminum plate material having a different thickness for each part so that the first, second and third parts 10, 20 and 30 may be formed to have different thicknesses from each other .

The first portion 10 may have a relatively low rigidity and may be formed thicker than the second portion 20 and the third portion 30. And the second portion (30) may be formed thinner than the third portion (30). This is because the third portion 30 is relatively less rigid than the second portion 30. For example, the first portion 10 may be formed with 5.0 t, the second portion 20 with 4.0 t, and the third portion 30 with 4.6 t.

Meanwhile, in the embodiment of the present invention, as shown in FIG. 4, the reinforcing plate 50 may be installed on the inner surface of the first portion 10. The reinforcing plate 50 reinforces the rigidity of the first portion 10 and is provided in a shape corresponding to the mounting surface 11 of the first portion 10.

Therefore, according to the vehicle shock absorber housing 100 according to the embodiment of the present invention configured as described above, since the structure is formed by using a tailor rolled blank (TRB) aluminum plate material having a different thickness for each part , Weight reduction can be achieved.

In addition, in the embodiment of the present invention, as compared with the shock absorber housing according to the comparative example having the same thickness (for example, 4.5t) made of aluminum material as in FIG. 5, The maximum concentrated stress of the first portion 10 and the maximum displacement of the first portion 10 can be reduced.

Thus, in the embodiment of the present invention, it is possible to improve the vibration performance of the vehicle by increasing the natural frequency while eliminating unnecessary weight increase, and by reducing the maximum stress and the maximum displacement, the rigidity of the shock absorber mounting portion can be increased.

Hereinafter, a method for forming a vehicle shock absorber housing 100 according to an embodiment of the present invention will be described.
