Description

[Detailed Description of the Invention] This invention relates to a stabilizer used in an automobile.

Generally, this type of stabilizer consists of a stabilizer bar made of spring steel, medium carbon steel, etc. in a substantially U-shape.
The stabilizer bar is disposed laterally on the chassis side of the vehicle and is rotatably supported on the chassis side at both ends, and the arm end of the stabilizer bar is attached to the axle side of the vehicle. Vehicles have been designed to reduce rolling of the vehicle body while driving and improve driving stability.

In recent years, there has been a tendency for such stabilizer bars to be formed in a hollow shape due to the reduction in weight of automobiles.

Therefore, normally, when the arm end of the hollow stabilizer bar is attached to the axle side of an automobile, the arm end is crushed and the crushed arm end is connected to the axle side.

However, the hollow stabilizer bar
The outer diameter is thin, like those used in passenger cars.
Regardless of the case where the wall thickness is relatively thin, the outer diameter is large and the outer diameter is large, such as those used for trucks.
When the wall thickness is relatively thick, it is difficult to crush the end of the arm by press working.

The purpose of this invention is to connect the arm end of the stabilizer bar to the axle side of the car easily and securely with sufficient strength, to reduce rolling of the car body when the car is running, and to improve driving stability. The purpose of this invention is to provide stabilizers used in automobiles that improve performance.

To solve these problems, the stabilizer used in the automobile of this invention consists of a hollow stabilizer bar placed laterally on the chassis side of the automobile, and the clevis connection part connects to the arm of the hollow stabilizer bar. It is characterized in that it is formed by crushing the arm ends so as to leave a predetermined space inside the ends, and that the crushed arm ends are filled with reinforcing material.

Hereinafter, preferred specific examples of the stabilizer used in an automobile according to this invention will be described with reference to the drawings.

Figures 1 and 2 show a specific example of a stabilizer used in an automobile of this invention used in a truck.
Showing 10.

The stabilizer 10 consists of a hollow stabilizer bar 11 disposed laterally below the chassis 20 at a position forward of the front suspension of the truck, and has a clevis connection 13.
The arm 1 of the hollow stabilizer bar 11 is arranged such that a predetermined space is left inside the end of the arm 12 of the hollow stabilizer bar 11.
formed by crushing the two ends, and the reinforcing material 14 is filled into the crushed end of the arm 12,
Through the clevis connection 13 and the clevis 15 bolted to the reinforcement 14, the end of the arm 12 is connected to the axle side of the truck, i.e.
The leaf as its front suspension.
It is rotatably connected to the spring 24 side.

The hollow stabilizer bar 11 is made of a carbon steel tube for machine structural use, and is bent into a substantially U-shape with a predetermined curvature so as to integrally form arms 12 at both ends.

The central portion of the hollow stabilizer bar 11 acts as a so-called torsion bar,
It is twisted according to the relative displacement of the ends of each arm 12, and the torsion torque generated by the displacement of one end of one arm 12 is transmitted to the other arm.

Of course, the outer and inner diameters of the hollow stabilizer bar 11, the central portion of the hollow stabilizer bar 11, and the effective length of the arms 12 are determined according to the vehicle weight of the truck.

Further, a padding 28 is arranged inside the bent portion of the hollow stabilizer bar 11. The filling 28 is the hollow stabilizer.
Considering the weight reduction of the bar 11, a relatively light one,
For example, it is desirable to use a hollow disposable pipe. Of course, the stuffing 28 is applied to the hollow stabilizer bar 11 in advance before the hollow stabilizer bar 11 is bent as described above.
When the hollow stabilizer bar 11 is bent with a predetermined curvature, the padding 28 is bent in substantially the same way.

A clevis connection portion 13 is formed at the end of each arm 12 of the hollow stabilizer bar 11 configured in this way.

The clevis connection portion 13 is formed by crushing the end of the arm 12 of the hollow stabilizer bar 11 from both left and right sides using a press machine so as to leave a predetermined space inside the end of the arm 12. .

By crushing the arm 12 end of the hollow stabilizer bar 11 in this way, the arm 1
The end face of No. 2 is deformed into a substantially oval shape.

The reinforcing material 14 is the arm 12 crushed in this way.
It is filled inside the end and is made of iron, synthetic resin, etc., and increases the strength of the arm 12 end.

Of course, the reinforcing material 14 is filled in the arm 12 end of the hollow stabilizer bar 11 before the arm 12 end is crushed as described above, and when the arm 12 end is crushed, the reinforcing material 14 has a substantially elliptical shape. transformed into.

The hollow stabilizer bar 11 so constructed is located in front of the leaf spring 24 as the front suspension of the truck.
The hollow stabilizer bar 11 is arranged laterally below the chassis 20 and is connected to the chassis 20 via brackets 26 at both ends of the central portion of the hollow stabilizer bar 11.
is rotatably supported.

Of course, a rubber bushing (not shown) is located inside the bore in the bracket 26 that rotatably supports the hollow stabilizer bar 11.

Further, a clevis 15 is bolted to a clevis connecting portion 13 formed at the end of the arm 12 of the hollow stabilizer bar 11.

The clevis 15 is made up of a pair of clamping plates 16 and 17 bent from a steel plate, with one end facing each other and the other end overlapping both sides of the clevis connecting portion 13. and its clevis connection part 1
3 is bolted to a reinforcing material 14 filled inside.

Furthermore, pin holes 18 and 19 are formed at one end of each of the clamping plates 16 and 17 at positions facing each other.

The clevis 15 thus fixed to the end of the arm 12 of the hollow stabilizer bar 11 is rotatably connected to the axle side of the truck, ie to the leaf spring 24.

The leaf spring 24 is equipped with a connecting plate 25 fixed to the lowest stage of a plurality of stacked leaf springs via a pair of U bolts 27, and the front eye of the leaf spring 24 is attached to the chassis 20. A rear bracket is rotatably connected to a fixed front bracket 21, and the rear eyepiece portion is spaced apart from the front bracket 21 by a predetermined distance, and is fixed to the chassis 20. 22 via a shackle 23 so as to be rotatable.

Of course, the connecting plate 25 fixed to the leaf spring 24 has an eye-shaped portion at its tip.

Therefore, the above-mentioned hollow stabilizer bar 11
A clevis 15 fixed to the end of the arm 12 is rotatably connected to the eye of the connecting plate 25.

Next, we will discuss the running of a truck to which the stabilizer 10 described above is applied. First, while the truck is running, the load is kept balanced on the left and right sides of the vehicle body, and due to vibrations on the axle side, If the leaf springs 24 are deformed under substantially the same conditions, the hollow stabilizer bar 11 will be
It is rotated following the deformation of the leaf spring 24 without being substantially twisted.

Further, when the truck turns and rolling occurs in the vehicle body, the displacement amount of the left and right leaf springs 24 is different, so the center portion of the hollow stabilizer bar 11 is twisted.
Due to the restoring force of the central part, the left and right arms 12
is returned to almost the same position.

That is, the stabilizer 10 bent by fitting the waste pipe 28 reduces the rolling of the vehicle body when the truck is running, and the running stability is improved.

According to this invention, in a stabilizer used in an automobile, which is composed of a hollow stabilizer bar placed laterally on the chassis side of the automobile,
a clevis connection is formed by collapsing an arm end of the hollow stabilizer bar to leave a predetermined space inside the arm end; and
Because the reinforcement material is filled into the collapsed arm end, the stabilizer bar arm end is
It is easily and reliably connected to the axle side of a car with sufficient strength, reduces rolling of the car body when the car is running, improves running stability, and becomes extremely practical.
