FIGS. 4 to 5 are views of a knuckle-axle beam assembly apparatus according to an embodiment of the present invention;
6 is a view showing an apparatus for assembling a knuckle and an axle beam according to another embodiment of the present invention.

Hereinafter, an apparatus for assembling a vehicle knuckle and axle beam according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

The apparatus for assembling a knuckle and axle beam of a vehicle according to an embodiment of the present invention includes a king pin 3 passing through an end of an axle beam 1 and a knuckle 2 as shown in Figs. An elastic member 15 provided between one end (lower side end portion) of the king pin 3 and the lower cover 14 coupled to the knuckle 2; And a compressive force adjusting the compression force of the elastic member 15 by connecting the elastic member 15 and the lower cover 14 to one end of the kingpin 3 and being provided on the lower cover 14 so as to be in contact with the elastic member 15, And an adjusting mechanism (16).

The tapered bearing 10 is coupled to the outer peripheral surface of the other end (upper side end) of the king pin 3 passing through the axle beam 1 and supports the knuckle 2; A king pin bush 11 coupled to an outer peripheral surface of one end (lower side end) of the king pin 3 passing through the axle beam 1 to support the knuckle 2; A fixing member (12) coupled to the other end of the king pin (3) to prevent the tapered bearing (10) from coming off; And a top cover (13) coupled to the knuckle (2) above the fixing member (12).

The kingpin 3 penetrates the axle beam 1 in a press-fit manner.

1, the left wheel 4 and the right wheel 5 having a hub and a drum are coupled to each other, and the knuckle 2 is provided with a tie rod arm 6 And the tie rod arm 6 is connected to the steering wheel 9 through the drag link 7 and the steering shaft 8. [

A concave groove 3a is formed at one end of the king pin 3 and a resilient member 15 is inserted into the concave groove 3a. It is possible to regulate the installation position of the elastic member 15. [

The elastic member 15 is connected to the knuckle 2 through the king pin 3, the compression force adjusting mechanism 16 and the lower cover 14 so as to be compressed As shown in FIG.

The elastic member 15 is preferably a rubber bush. However, the present invention is not limited thereto, and a spring or a plastic resin may be used if necessary.

The compression force adjusting mechanism (16) includes an adjusting bolt (161) penetrating through the lower cover (14) and having one end in contact with the elastic member (15); And a lock nut 162 coupled to the tartan of the adjustment bolt 161.

The adjustment bolt 161 is installed such that the head portion 161a of the adjustment bolt 161 contacts the elastic member 15 so that the adjustment bolt 161 can contact the elastic member 15 with a wider area, So that the supporting force of the knuckle 2 can be further strengthened.

At the other end of the adjustment bolt 161, a tool insertion groove 161b is formed for the operation of the adjustment bolt 161 using a tool.

In this case, it is preferable to adjust the adjusting bolt 161 so that the elastic member 15 always has the optimum compression force.

A bolt hole 14a through which the adjustment bolt 161 passes is formed in the lower cover 14. The bolt hole 14a is provided with a sealing member 17 and the sealing member 17 Is provided in contact with the adjustment bolt 161 so as to maintain the airtightness between the lower cover 14 and the adjustment bolt 161 so that the leakage of the grease existing in the knuckle 2, .

The sealing member 17 is preferably formed of rubber, silicone, or resin.

Hereinafter, the operation of the embodiment of the present invention will be described.

The king pin bush 11 sandwiched between the outer peripheral surface of the one end (lower side end) of the king pin 3 and the knuckle 2 is made of bronze material such as a material susceptible to abrasion, bump) and rebound (external force).

When the king pin bush 11 is worn as described above, a gap C1 is generated between the knuckle 2 and the king pin 3 as shown in FIG. 3. When the knuckle 2 is braked by the gap C1, And the vibration of the knuckle 2 is transmitted to the steering wheel 9 through the steering system. As a result, the steering wheel 9 also vibrates at the same time as the steering wheel 9 is tilted. Further, Lt; / RTI >

Even if the king pin bush 11 inserted between the knuckle 2 and the king pin 3 is worn and the gap C1 is generated between the knuckle 2 and the king pin 3 The knuckle 2 can be held firmly and firmly and the knurling of the knuckle 2 due to the gap C1 and the shaking of the steering wheel 9 during braking can be eliminated, It is possible to minimize the occurrence of uneven wear of the bearing.

That is, according to the embodiment of the present invention, the elastic member 15 and the adjusting bolt 161 connect the king pin 3 and the lower cover 14 with a strong supporting force. When the lower cover 14 is connected to the knuckle 2, Even if a gap C1 is generated between the knuckle 2 and the king pin 3 due to abrasion of the kingpin bush 11, the knuckle 2 does not contact the lower cover 14, the adjusting bolt 161, It is possible to maintain a stable supporting force with the king pin 3 through the elastic member 15. This makes it possible to eliminate the vibration of the knuckle 2 and the vibration of the steering wheel 9 during braking, The occurrence of uneven wear of the tire can be minimized.

6, the assembling apparatus of another embodiment according to the present invention is shown. In this case, without using the compression force adjusting mechanism 16 and the sealing member 17 used in the embodiment shown in Figs. 4 to 5, (15) to support the king pin (3) and the lower cover (14).

That is, an apparatus for assembling a knuckle and axle beam according to another embodiment of the present invention includes a kingpin 3 passing through an end of an axle beam 1 and a knuckle 2; A lower cover 14 coupled to the knuckle 2 to cover one end of the king pin 3 passing through the axle beam 1; And an elastic member 15 installed between one end of the king pin 3 and the lower cover 14 to strengthen the supporting force of the knuckle 2 through the connection of one end of the king pin 3 and the lower cover 14 .

The elastic member 15 is a structure provided in the concave groove 3a of the king pin 3 in a compressed state as a rubber bush.

It is not necessary to use the compression force adjusting mechanism 16 on the assumption that the elastic member 15 has a compressive force capable of sufficiently supporting the knuckle 2 through the lower cover 14. [

At this time, the knuckle 2 maintains a firm holding force with the king pin 3 through the lower cover 14 and the elastic member 15, so that the knuckle 2 And the wobble of the steering wheel 9 can be eliminated. Further, occurrence of uneven wear of the tire can be reduced as much as possible.
