Description

[0001] STRUT BEARING ASSEMBLY FOR VEHICLE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a vehicle strut bearing assembly, and more particularly, to a vehicle strut bearing assembly, in which a seat member is firmly and stably coupled to a lower housing of a housing having a strut bearing.

Generally, a suspension system of an automobile connects an axle and a vehicle body to prevent a vehicle or a cargo from being damaged, thereby preventing a vibration or an impact which an axle receives from the road surface from being transmitted directly to the vehicle body when the vehicle is running .

Such suspension devices are variously classified according to the method of coupling with the vehicle body and the vibration control method. The front suspension device classified according to the type of the front axle supports the weight of the vehicle by connecting the vehicle body frame and the axle, And at the same time a part of the steering apparatus of the automobile is installed.

The front suspension system is divided into an axle suspension system and an independent suspension system. In the case of passenger cars, which emphasize ride comfort and maneuverability, independent suspension systems are used. In buses, trucks and commercial vehicles, axle suspension systems are frequently used.

Particularly, the front suspension devices of the independent suspension type include Wishbone type and Macpherson type. In the case of the Macpherson type, the structure is simple and the ride feeling is superior to that of the Wish type, It is the way it is used.

Such a McPherson type suspension device has no upper arm and instead has a structure in which the steering knuckle and the strut are integrally rotated when the lower end of the strut with the shock absorber incorporated is integrally connected to the lower arm through the steering knuckle, The upper portion of the strut is rotatably mounted relative to the vehicle body or the chassis via a strut bearing so as to be rotatable integrally with the steering knuckle.

FIG. 1 shows an example of a conventional McPherson type suspension device. A knuckle 20 to which a steering device (not shown) is connected for steering the wheel 10 is mounted on the wheel 10 through a wheel bearing And the lower end of the strut 30 along the height direction of the vehicle is inserted and coupled to one of the knuckle arms 22 among the plurality of knuckle arms 22 formed on the knuckle 20. The upper end of the strut 30 is not shown And is mounted to the vehicle body via the insulator 40. [

The strut 30 includes a shock absorber 32 to which a lower end is fitted and supported by the knuckle arm 22 and a coil spring 34 wound around the outer circumferential surface of the shock absorber 32, The shock absorber 32 and the coil spring 34 absorb vibration and shock transmitted to the vehicle body through the wheel 10 to absorb the impact.

The strut 30 is also rotated together with the knuckle 20 when the wheel is steered while the knuckle 20 is turned according to the operation of the steering apparatus and the upper end of the strut 30 is coupled to the vehicle body, Must be able to rotate relative to the body.

The upper end of the strut 30 is mounted via a strut bearing assembly 50 which includes a strut bearing and an insulator 40 to an unillustrated vehicle body in order to enable relative rotation of the strut 30. [

The conventional strut bearing assembly 50 includes upper and lower housings that are coupled so that a strut bearing is mounted therein. The upper and lower housings 50 and 60 are provided to prevent foreign matter and moisture from entering the inside of the strut bearing, And a seal member mounted between the seal members.

However, in the conventional strut bearing assembly 50 as described above, the seal member is usually bonded to the lower housing or coupled by injection or vulcanization. In this case, the lower housing and the seal member are made of different materials. There is a disadvantage that the sealing force is deteriorated and the sealing member is easily detached from the lower housing, resulting in a quality problem.

In addition, when the seal member is detached, the lubrication performance of the strut bearing deteriorates due to the leakage of the grease filled in the upper and lower housings for lubrication of the strut bearing, and at the same time, foreign matter and moisture may flow into the strut bearing, And the overall durability is deteriorated.
