Description

The present invention includes a method of manufacturing the stabilizer bushing with stabilizer bar, a bonding jig of the stabilizer bush for use in mounting the stabilizer bush to the stabilizer bar and the stabilizer bushing adhesive article of the stabilizer bar is relates.

Conventionally, it has been considered to provide a stabilizer bar in order to reduce the inclination of a vehicle body of an automobile or the like and improve traveling stability. This stabilizer bar is a torsion bar spring (torsion bar), and by attaching both ends to a suspension, for example, the left and right wheels are prevented from moving vertically differently.

In addition, a stabilizer bush is attached to an intermediate portion of the stabilizer bar, and the intermediate portion of the stabilizer bar is attached to a body, a subframe, or the like via the stabilizer bush. As disclosed in Japanese Patent Laid-Open No. 2006-170257 (Patent Document 1), this stabilizer bush has a cylindrical bush body formed of a rubber elastic body and externally inserted to the stabilizer bar, and a radial direction on the outer peripheral surface of the bush body. And a half member of a bracket metal member that is attached by being overlapped from both sides in one direction. The stabilizer bush is attached to the stabilizer bar in a state where the bush body is externally inserted into the stabilizer bar and the inner peripheral surface of the bush body and the outer peripheral surface of the stabilizer bar are adhered to each other.

By the way, in order to bond the bush body to the stabilizer bar, it is necessary to heat the bush body while keeping the inner peripheral surface of the bush body pressed against the outer peripheral surface of the stabilizer bar.

However, when pressing the half parts of the bracket metal parts toward each other and compressing the bushing body located on the inner peripheral side of the bracket metal parts radially and pressing it against the stabilizer bar, the bracket metal parts are pressed. Since the pressing jig for doing so is pressed against the bracket metal fitting, there is a risk that the coating generally applied to the surface of the bracket metal fitting may be peeled off for the purpose of rust prevention and the like. In particular, if heating is performed to bond the bush main body and the stabilizer bar, the coating of the bracket fitting softens and is easily transferred to the pressing jig, and therefore the peeling of the coating of the bracket fitting is likely to be a problem.

In Patent Document 1, the intermediate plate fixed to the radial middle portion of the bush main body projects axially outward from the bush main body, and the intermediate plate is pressed by a pressing jig to remove the bush main body. The inner peripheral surface is pressed against the outer peripheral surface of the stabilizer bar. However, when the intermediate plate is pressed by the pressing jig as in Patent Document 1, the intermediate plate is indispensable in the stabilizer bush, and the degree of freedom in adjusting the vibration-proof characteristics of the stabilizer bush decreases, and the intermediate plate is used in the bush body. By projecting axially outward from the stabilizer bush, the stabilizer bush becomes too large in the axial direction.

The relative displacement between the second bracket metal fitting 22 and the second bracket metal fitting 22 is kept limited by the bonding jigs 48, 48. As a result, the bush body 18 is compressed in the direction perpendicular to the axis between the first bracket fitting 20 and the second bracket fitting 22, and the inner peripheral surface of the bush main body 18 is kept pressed against the outer peripheral surface of the stabilizer bar 12. To do. Further, in the mounted state of the bonding jig 48, the outer peripheral surface of the bush main body 18 is pressed against the first mounting portion 40 of the first bracket metal fitting 20 and the second mounting portion 44 of the second bracket metal fitting 22. Retained. The first fastening piece 42 and the second fastening piece 46, which are sandwiched and held by the bonding jig 48, do not necessarily have to be overlapped with each other in an abutting state, and they are overlapped with a predetermined gap. Alternatively, it may be positioned and held by the bonding jig 48 in a state of being indirectly contacted via another member and overlapped.

Next, while the first bracket metal fitting 20 and the second bracket metal fitting 22 are relatively positioned and held by the bonding jig 48, the stabilizer bar 12 and the stabilizer bush 14 are placed in a constant temperature bath and heated to thereby heat the bush body. 18 and the stabilizer bar 12, and the adhesive between the bush main body 18 and the first and second bracket fittings 20 and 22 are respectively cured, so that the bush main body 18 and the stabilizer bar 12 and the first and second brackets. The bracket metal fittings 20 and 22 are bonded. The stabilizer bar 12 and the stabilizer bush 14 are held in a constant temperature bath at a temperature of 120° C. or higher for a predetermined time, and more preferably at 150° C. or higher.

By completing such an adhering step, the stabilizer bush 14 is attached to the stabilizer bar 12 in an externally attached state, and the first and second bracket fittings 20 and 22 are fixed to the bush body 18. After the bonding process is completed, the bonding jig 48 is removed from the first and second bracket fittings 20 and 22 to obtain the stabilizer bar 10 with stabilizer bushes. In this embodiment, since the bonding jig 48 has a structure that closes the bolt hole 47, the bonding jig 48 is removed from the first and second bracket fittings 20 and 22 after the bonding process is completed. However, when the bonding jig 48 has a structure that does not hinder the functions of the first and second bracket fittings 20 and 22, the bonding jig 48 may be left attached. Further, when the elasticity of the bush body 18 causes the first and second bracket metal fittings 20 and 22 to be displaced in the direction away from each other after the bonding step is completed, the first and second bracket metal fittings 20 and 22 are overlapped with each other. It is desirable to avoid excessive rubbing or catching of the bonding jig 48 on the first and second bracket fittings 20 and 22 by removing the bonding jigs 48 and 48 while exerting an external force for pressing.

Here, the surface roughness of the first and second contact surfaces 56 and 58 of the bonding jig 48 covered with the coating layer 60 is determined by the first and second fastening pieces of the first and second bracket fittings 20 and 22. It is smaller than the surface roughness of the upper and lower outer surfaces of 42 and 46. This makes it difficult for the coating to adhere to the first and second contact surfaces 56, 58 of the bonding jig 48 on the upper and lower outer surfaces of the first and second fastening pieces 42, 46 with which the bonding jig 48 abuts. Therefore, deterioration of the durability of the first and second bracket fittings 20 and 22 due to peeling of the coating can be prevented.

The effect of preventing the adhesion of the coating to the first and second contact surfaces 56 and 58 is, for example, by reducing the unevenness of the first and second contact surfaces 56 and 58, thereby making the bonding jig 48 and the first contact surface. The electrostatic charging due to the friction between the second bracket fittings 20 and 22 is reduced, and the paint hardly adheres to the first and second contact surfaces 56 and 58 of the bonding jig 48. Further, since the fine irregularities of the first and second contact surfaces 56 and 58 are made smaller, the paint softened by heating enters the fine concave portions of the first and second contact surfaces 56 and 58 to anchor the anchor. The effect is reduced, and the paint is prevented from adhering to the first and second contact surfaces 56, 58.

Further, in the present embodiment, by covering the surfaces of the first and second contact surfaces 56, 58 of the bonding jig 48 with the coating layer 60, it is possible to easily set a small surface roughness. Moreover, since the coating layer 60 is made of fluororesin, the surface roughness is set to be sufficiently small, and the heat resistance against high temperature when the bush body 18 and the stabilizer bar 12 are adhered to each other and the coating surface are improved. Further, it is possible to prevent the paint from peeling off due to the substantially non-polar property and reduce the interaction, and to improve the durability of the bonding jig 48 due to the excellent wear resistance.

Further, the first bracket fitting 20 is provided with a first fastening piece 42 projecting to the outer circumference, and the second bracket fitting 22 is provided with a second fastening piece 46 projecting to the outer circumference. 42 and the second fastening piece 46 are superposed on each other and sandwiched between the first and second pressing portions 50 and 52 of the bonding jig 48. Thereby, the bonding jig 48 of the present embodiment is compared with a case where the first mounting portion 40 of the first bracket metal fitting 20 and the second mounting portion 44 of the second bracket metal fitting 22 are sandwiched and held, for example. Can be made compact. Moreover, since the first and second pressing portions 50 and 52 are integrally connected by the connecting portion 54, the entire bonding jig 48 is integrated, and the handling is easy.

Further, the stabilizer bush 14 formed in the state of being mounted on the stabilizer bar 12 by the above-described manufacturing method has the bush body 18 adhered to the first and second bracket fittings 20 and 22, so that abnormal noise due to rubbing occurs. Generation and wear are prevented. Further, when the bush body 18 is adhered to the stabilizer bar 12, the bush body 18 and the first and second bracket fittings 20 and 22 are adhered at the same time, so that an increase in the number of manufacturing steps can be avoided and the adhesion curing can be performed. By the tool 48, the bush body 18 and the first and second bracket fittings 20 and 22 can be effectively bonded in a state of being in close contact with each other.

Further, in the stabilizer bush 14 of the present embodiment, the first and second intermediate plates 30 and 36 are vulcanized and bonded to the bush body 18, and the spring characteristic of the bush body 18 is adjusted. Furthermore, since it is possible to press the first and second bracket fittings 20 and 22 with the bonding jig 48 in the bonding step, the first and second intermediate plates 30 and 36 are bonded to the bonding jig. Since it is not necessary to project the first and second rubber elastic bodies 28, 34 axially outward from the axial end portions so that they can be pressed by 48, the bush body 18 can be made smaller and lighter.
