Description

Front wheel dual shock absorber for vehicle {Dual shockabsorber for a car}

The present invention relates to a front wheel dual shock absorber for a vehicle, and more particularly, because of its simple structure, it can be installed regardless of a new vehicle or an existing vehicle, and thereby provides excellent riding comfort by increasing the vibration absorption function of the vehicle. It's about the front wheel dual shock absorbers.

[Background Art] A shock absorber is installed in a suspension system of a vehicle as a means for absorbing shock and improving riding comfort. Shock absorbers are also called simply shock absorbers.

The shock absorber is connected between the body frame and the wheel support frame to provide a comfortable riding experience by controlling the tension and compression of the spring in both directions.

Depending on the structure of the shock absorber, a hydraulic type and a gas type are generally used. The hydraulic type absorbs shock by the pressure of oil, and the gas type uses both the pressure of oil and the repulsive force of gas to provide a buffering effect.

Either way, a shock absorber is a technology that is generally widely used in vehicles, and it is common that one such shock absorber is applied to a normal vehicle, particularly to the front wheel region of a vehicle.

Of course, even if a single shock absorber is applied, it is possible to provide a buffering function, but due to structural limitations, it is difficult to completely absorb vibrations introduced into the vehicle, and thus there is a limit to improving ride comfort.

Therefore, as an alternative, the application of a dual shock absorber can be considered, but the structure of the front wheel area is complicated and adoption is difficult.

Even so, if you apply a dual shock absorber in a too complicated form, it can rather cause an increase in cost, and also considering that future maintenance will inevitably become difficult, a front wheel dual shock absorber for a previously unknown vehicle The need for is emerging.
