Description

  The present invention relates to a stabilizer bush used for a vehicle stabilizer and a vehicle stabilizer incorporating the stabilizer bush, and more particularly to a technique capable of improving the stability and maneuverability of a vehicle.

  A vehicle stabilizer in which a stabilizer bush is incorporated has a function of connecting a stabilizer bar to a suspension device of the vehicle and stabilizing the posture of the vehicle using a torsional reaction force of the stabilizer bar. For example, in a vehicle stabilizer, the ends of a U-shaped stabilizer bar are connected to the operating part of the suspension device, and the torsion part of the stabilizer bar is fixed to the vehicle body frame with the stabilizer bush (fixing member), and the torsional reaction force (See, for example, Patent Document 1).

  The stabilizer bush has a shape that holds a predetermined position of the torsion portion, and is fixed to the vehicle body frame side. The stabilizer bush is generally a sliding bush, and has a structure that moves relatively along the axial direction of the torsion portion.

JP 2001-270315 A

  In the case where the above-described stabilizer bush is mounted on the stabilizer bar, there is the following problem. That is, since the stabilizer bush moves relatively along the axial direction of the torsion part, the stabilizer bush may interfere with parts other than the torsion part, and abnormal noise may occur. Further, the relative positional relationship between the stabilizer bush and the torsion portion is deviated, so that the performance as the vehicle stabilizer is unstable, which adversely affects the steering stability and the ride comfort.

  Further, there is a problem that muddy water enters the gap between the torsion part and the stabilizer bush, and noise is generated due to rubbing.

  Furthermore, as a measure for improving the above-mentioned problems, there is a method for preventing misalignment between the torsion part and the stabilizer bush by bending the torsion part, but there is a problem that the manufacturing cost increases. .

  Therefore, the present invention provides a stabilizer bush and a vehicle stabilizer that can improve steering stability and ride comfort and prevent abnormal noise by preventing misalignment with the stabilizer bar and intrusion of muddy water. The purpose is that.

  In order to solve the problems and achieve the object, the stabilizer bush and the vehicle stabilizer of the present invention are configured as follows.

  A stabilizer bush attached to a vehicle stabilizer having a torsion portion extending in the vehicle width direction and an arm portion extending in the vehicle front-rear direction from both ends of the torsion portion, and attached to the outer peripheral portion of the torsion portion via an adhesive And a bracket fixed to the bush via an adhesive and attached to the vehicle body.

  A torsion part that extends in the vehicle width direction and has an engaged part, an arm part that extends from both ends of the torsion part in the vehicle front-rear direction, and an engagement part that engages with the engaged part of the torsion part A stabilizer bush that is attached to the torsion part, and the engaged part is knurled or double-sided, and the stabilizer bush is attached to an outer peripheral part of the torsion part via an adhesive. The bracket is fixed to the bush via an adhesive and is attached to the vehicle body.

  According to the present invention, it is possible to improve the steering stability and the ride comfort and prevent the generation of abnormal noise by preventing displacement with respect to the stabilizer bar and intrusion of muddy water.

  FIG. 1 is a perspective view showing a vehicle stabilizer 10 and a vehicle front wheel suspension device K according to a first embodiment of the present invention, and FIG. 2 shows a stabilizer bar 20 incorporated in the vehicle stabilizer 10 to a torsion portion 21. It is a perspective view which shows the bush (fixing member) 30 for stabilizers.

  The vehicle stabilizer 10 includes a stabilizer bar 20 made of a hollow member or a solid member, a stabilizer bush 100 for fixing the stabilizer bar 20 to the frame portion F of the vehicle body, and a tip 23a of the stabilizer bar 20 at the suspension device K. And a stabilizer link 30 connected to the operating portion.

  The stabilizer bar 20 is positioned at both ends of the torsion part 21 passed in the vehicle body width direction, the shoulder part 22, and the shoulder part 22. It is provided and is formed in a substantially U shape.

  The stabilizer bar 20 has a function of holding the suspension device K stably by the torsional reaction force of the torsion portion 21 when the operating portion of the suspension device K moves up and down, and the arm portion 23 follows the movement. Have. The attachment portion 21a corresponding to the stabilizer bush 100 of the torsion portion 21 is deformed by rolling, cutting, or the like so that the cross section is an ellipse (for example, two-side width processing).

  As shown in FIG. 2, the stabilizer bush 100 includes a bush 110 attached to the outer peripheral portion of the torsion portion 21 via an adhesive (epoxy adhesive or post-curing adhesive), and an adhesive on the bush 110. And a bracket 120 attached to the vehicle body.

  The bush 110 is formed of a rubber material, and is provided with an inner wall surface 111 having a shape along the outer peripheral surface of the attachment portion 21a. The outer wall surface 112 is formed of an arc portion and a straight portion. Further, a bush split portion 113 serving as an opening is formed in the lower portion in FIG.

  The bracket 120 is formed by bending a metal plate, and is formed at a bent portion 121 having an inner wall surface 121a formed along the outer wall surface 112 of the bush 110, and at both ends of the bent portion 121. And a joining portion 122 provided for joining with F. Note that a bolt hole 122 a is formed in the joint portion 122.

  The suspension device K is, for example, a double wishbone type suspension device, and front wheels and the like (not shown) are attached to axle portions Ka provided on the left and right.

  The stabilizer bush 100 described above is manufactured by the following process. That is, after an epoxy adhesive or a post-curing adhesive is applied to the attachment portion 21a of the torsion portion 21 of the stabilizer bar 20, the bush split portion 113 is spread and bonded to a predetermined position. An adhesive is also applied to the inner wall surface 111 of the bush 110. Thereafter, epoxy powder coating is applied to the stabilizer bar 20 to further strengthen the adhesive force.

  In order to ensure adhesion, the surface treatment of the bracket 120 may use cationic coating or galvanization.

  Next, an adhesive is applied to the inner wall surface 111 and the outer wall surface 112 of the bush 110, and the bracket 120 is overlapped.

  The vehicle stabilizer 10 thus configured operates as follows. That is, for example, it is assumed that a wheel on one side enters a recess and one of the suspension devices K is lowered while the vehicle is running. Then, a sandwiching angle is generated in the left and right arm portions 23 or the sandwiching angle is widened, so that the torsion portion 21 is twisted and a twisting reaction force is generated. This torsional reaction force causes the torsion part 21 to return to its original state and return the suspension device K to its original position.

  At this time, the frame part F and the bracket 120 are bolted, and the bracket 120 and the bush 110 are firmly fixed by an adhesive. Moreover, since the attachment part 21a has a flat surface formed by two-sided width processing, the adhesive force becomes stronger. Therefore, relative displacement between the frame part F and the attachment part 21a of the torsion part 21 does not occur.

  On the other hand, when the displacement prevention force between the bracket 120 and the bush 110 exceeds the input load, the bonding area between the bracket 120 and the bush 110 may be reduced.

  For this reason, the following effects are acquired. That is, since the bush 110 and the bracket 120 do not move from the attachment site 21a, interference with other parts can be avoided. Further, by stabilizing at the nominal (regular) position, the deflection characteristic of the stabilizer bar 20 is stabilized.

  In addition, the accuracy of the trace is improved during a reverse phase stroke such as turning. For this reason, a feeling of floating of a tire decreases and sensory evaluation improves.

  On the other hand, during a common-phase stroke such as when traveling straight, stick slip that slips intermittently does not occur, so the stroke has a linear characteristic, there is no discontinuity, and riding comfort is improved.

  Further, since muddy water does not enter between the stabilizer bush 100 and the bracket 120, it is possible to prevent the generation of noise due to rubbing.

  Furthermore, it is not necessary to attach an aluminum ring or a rubber clamp on the bush side to the torsion portion 21 for bending processing or preventing misalignment of the stabilizer bush 100. Therefore, the number of parts can be reduced and the degree of freedom in design is improved.

  As described above, in the stabilizer bush 30 according to the present embodiment, by preventing misalignment with the stabilizer bar 20 and intrusion of muddy water, the steering stability and the ride comfort are improved, and the generation of abnormal noise is prevented. Can do.

  In addition, an anchor effect may be added and the adhesive force may be further improved by performing a matte treatment on either or both of the inner wall surface 111 of the bush 110 and the painted surface of the stabilizer bar 20.

  Normally, the swing angle of the stabilizer link is designed taking into account the amount of deviation between the stabilizer and the bush, but since the amount of deviation becomes zero due to adhesion, the required swing angle of the stabilizer link can be reduced, reducing costs. And toughness to seal durability can be expected. Further, when a deviation occurs between the stabilizer and the bush, the stabilizer responds after the deviation stops, but the stabilizer response is improved by eliminating the deviation.
