Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing a stabilizer from laterally shifting to prevent the position of a stabilizer mounted on an automobile or the like from fluctuating.

[0002]

2. Description of the Related Art FIG. 14 is a perspective view of a stabilizer 1. The stabilizer 1 is entirely made of an elastic rod material, and a tip portion 3, 3 on both sides with respect to a central base 2 in the same direction. This is a kind of torsion spring which is bent at right angles and formed into a U-shape, in which a center base 2 is pivotally supported on a vehicle body floor structure, and front ends 3 and 3 on both sides are connected to an axle.

[0003] The stabilizer 1 functions to convert energy generated by rolling motion of the vehicle body during running into a torsional motion of the base 2 and absorb the energy. If the lateral displacement causes the position to fluctuate, it affects the axle and deteriorates the running performance. Therefore, it is necessary to prevent the lateral displacement in which the stabilizer 1 is displaced in the axial direction of the base 2.

[0004] As one of the conventional devices for preventing lateral displacement of the stabilizer 1, a base portion 2 of the stabilizer 1 in which an elastic bar material having a uniform cross-sectional shape is formed in a U-shape is subjected to hot thrust force in the compression direction. 14 to form plastically deformed flanges 4 near the pivotal position of the base 2 as shown in FIG. In other words, a means for contacting the pivot member is adopted.

[0005] Further, as another conventional apparatus for preventing lateral displacement of the stabilizer 1, as shown in FIG.
An inner ring member 5 made of rubber or the like having a large coefficient of friction is wound around the pivotal position of the base portion 2 of the stabilizer. Means has been adopted in which the inner ring member 5 is prevented from sliding relative to 2, and the side surface of the inner ring member 5 is brought into contact with a pivotal support member on the vehicle body floor structure side.

Further, as another conventional apparatus for preventing lateral displacement of the stabilizer 1, as shown in FIG.
An axially inclined taper 7 is formed on the outer peripheral surface in the vicinity of a pivotal support position at the base of the stabilizer, and an axial cut 8 and a thin portion 9 are provided at opposing locations on one diameter. Alternatively, an outer ring body 12 of a press-formed product in which a resin inner ring body 10 is fitted and a taper 11 which is inclined at the same gradient as the taper 7 is formed on an inner peripheral surface of the inner ring body 10.
Is press-fitted, the inner ring body 10 grips the vicinity of the pivot position at the base of the stabilizer tightly, and the side surface of the inner ring body 10 is brought into contact with the pivot member on the vehicle body floor structure side.

[0007]

However, the device for preventing lateral displacement of the stabilizer 1 formed with the flange 4 shown in FIG. 14 applies a thrust force in the compression direction to the base 2 of the stabilizer 1 to plastically deform it. There was a problem that the process became complicated.

Further, in the device for preventing lateral displacement of the stabilizer shown in FIG. 15, a large fastening force cannot be expected on the thin metal sheet strip 6, and there is a problem that the inner ring member 5 slides when receiving a large lateral force.

Further, the stabilizer lateral displacement preventing device shown in FIG. 16 can be expected to have a large tightening force. However, some stabilizers 1 have both ends 3 and 3 (see FIG. 14) having a rectangular cross section. In some cases, the body 12 could not be fitted.

SUMMARY OF THE INVENTION It is an object of the present invention to solve such a conventional problem and to provide an apparatus for preventing lateral displacement of a stabilizer which can be easily attached to a stabilizer of any shape and strongly tightened.

[0011]

According to the present invention, there is provided an inner ring body made of a polymer material, having an outer peripheral surface formed with an axial taper and divided in a circumferential direction to surround a vicinity of a pivot position of a stabilizer base. A taper having the same gradient as the taper of the outer peripheral surface of the inner ring body is formed in the inner surface circumference in the axial direction, and is divided in the circumferential direction, and its ends are mutually connected to form an inner ring body. An outer ring body firmly fitted to the outer peripheral surface, and relates to an apparatus for preventing lateral displacement of a stabilizer, wherein an inner ring body is mounted around a vicinity of a pivotal support position of a stabilizer base, and an appropriate The outer ring body is connected to the inner ring body at that position, and the outer ring body is moved toward the inner ring body from that position to be fitted, and the taper of the inner ring body outer peripheral surface and the outer ring body inner surface taper are mutually connected. The inner ring is stabilized by press fitting Part pivot position is gripped tightly around the vicinity of, by contacting the side surface of the inner race to the pivot member of the vehicle body floor structure side, it is possible to reliably prevent the lateral displacement of the stabilizer.
