Description

Bush structure of vehicle suspension

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bush structure of a vehicle suspension device. In particular, a pipe is provided in a bush installed in a lower arm of a front suspension device, and an inner pipe is installed at an inner circumference of the bush. The present invention relates to a bush structure of a vehicle suspension device capable of absorbing vibration and impact force transmitted from a road surface while driving.

In general, the suspension of the vehicle is to reduce the shock or vibration transmitted from the road surface while driving to improve the adhesion between the wheel and the road surface, and to improve the riding comfort.

The conventional structure of the front suspension is provided with a shock absorber (1) in the upper front wheel, as shown in Figure 1, the front has a lower arm (2) for controlling the movement of the wheel and connected to the axle, Stabilizer control link (4), stabilizer (3) and cross member (6) is installed in the lateral direction, the transverse member (5) is installed in the lower part, the engine member (7) is installed in the center front.

The front of the lower arm (2) is provided with a bush (8) as shown in Figure 4, the outside of the bush (8) is provided with a rubber (9), the inner circumference is provided with an inner pipe (10).

However, this suspension system controls the flow of the wheel, and the bush 8 installed on the lower arm 2, which is connected to the cross member 6 and the axle by two points, becomes the rubber 9, and the inner pipe 10 ) Is insufficient to absorb vibrations and shocks transmitted from the road surface while driving.

The above-described prior arts have a problem of impairing the quietness of the vehicle because external vibration and shock are transmitted to the axle through the inner pipe of the bush.

SUMMARY OF THE INVENTION The present invention has been made to solve the above conventional problems, and includes a pipe inside a bush installed in a lower arm of a front suspension device, and an inner pipe is provided at an inner circumference of the bush. The purpose of the present invention is to make it possible to absorb vibrations and impact force transmitted from the road surface while driving and to strengthen the rubber by the inner pipe, thereby improving the quietness of the vehicle by smoothing the road impact and vibration during driving.

Hereinafter, the configuration of the present invention in detail.

The bush 8 provided in the lower arm 2 of the front suspension of the vehicle is made of the rubber 9 material, and the inner pipe 10 is provided with an inner pipe 10, so that the rubber of the bush 8 is provided. (9) A pipe 11 is provided inside, and an inner pipe 10 is installed at the inner circumference of the rubber 9 to absorb vibrations and shocks transmitted from the road surface.

Referring to the configuration of the present invention configured as described above in detail.

As shown in FIG. 1, a shock absorber 1 having a spring is provided at an upper portion of a front wheel, a lower arm 2 is installed at a front side thereof, and a stabilizer control link 4 and a stabilizer 3 are disposed in a lateral direction. Install the cross member (8).

The transverse member 5 is installed at the lower portion of the cross member 6, the engine member 7 is installed at the center front, and the bush 8 is located at the front of the lower arm 2 connected to the cross member 6. Install it to connect with the axle.

As shown in FIG. 3, the bush 8 includes a pipe 11 recessed inside the rubber 9, and an inner pipe 10 is provided at an inner circumference of the rubber 9.

Referring to the operation of the present invention as described in detail as follows.

When the vibrations and impacts generated from the road surface are transmitted to each rod and the lower arm 2 and transmitted to the bushes 8, the vibrations and impact forces are primarily transmitted by the pipes 11 provided in the rubbers 9 of the bushes 8. Offset.

The vibration and impact force first offset in the pipe 11 of the rubber 9 of the bush 8 are second offset when transmitted to the inner pipe 10 and the axle through the rubber 9 inside the pipe 11. do.

This makes it possible to absorb more vibration and shock in the rubber 9 and the pipe 11 of the bush 8 to relatively reduce the vibration.

Therefore, the vehicle is firmly supported in the left and right directions of the vehicle, and softness is applied in the front and rear directions and the rotational direction to cancel the impact of the road surface while driving, thereby minimizing the shock and vibration applied to the vehicle body. It is.

As described above, the present invention is provided with a pipe inside the bush installed in the lower arm of the front suspension, and an inner pipe is installed at the inner circumference of the bush to transmit vibration from the road surface while driving and Since the impact force can be absorbed, there is an effect of increasing the quietness of the vehicle to improve the riding comfort and improving the merchandise of the vehicle.
