Description

The present invention relates to a method of assembling an elastic support device for a stabilizer bar that elastically supports a stabilizer bar of a vehicle by inserting it through an insertion hole of a stabilizer bar bush.

The stabilizer bar is a torsional rigid spring (torsion bar) that is attached to reduce the inclination of the vehicle body, and both ends thereof are attached to the left and right suspensions, and acts to suppress this when the left and right wheels move differently.
For example, when turning a corner, the suspension tends to contract on the outer ring side due to centrifugal force and to extend on the inner ring side. As a result, the vehicle body tends to tilt outward due to centrifugal force.
The stabilizer bar thus generates torsion when the left and right wheels move in the opposite phase (rolling), suppresses the opposite phase movement of the left and right wheels by resistance due to its torsional rigidity, and stores the elasticity stored by the torsion. It works to quickly restore the left and right wheels that have moved in opposite phases with the restoring force.

As described above, the stabilizer bar has a function of suppressing the roll angle, thereby improving the running stability of the vehicle.
When the stabilizer bar is attached to the vehicle body side member, a stabilizer bar bush as a vibration insulating member is interposed between the vehicle body side member and the stabilizer bar so as to elastically support the stabilizer bar.

FIG. 13 shows an example of a conventional elastic support device including the stabilizer bar bush.
In the figure, reference numeral 200 denotes a stabilizer bar bush which is a main element of the elastic support device 201, and is substantially composed of rubber.
The stabilizer bar bush has an insertion hole 202, through which a stabilizer bar 204 is inserted and elastically supported.

Reference numeral 206 denotes a mounting bracket for mounting the stabilizer bar bush 200 to the vehicle body side member 212, and has a U-shaped holding portion 208 and a pair of fixing portions 210. It is fixed to the side member 212.
The holding part 208 has a pair of upright walls 214 that rise in a direction away from the vehicle body side member 212 with respect to each fixing part 210, and a semicircular connection part 215 that connects each of the ends. The stabilizer bar bush 200 is held in the fitted state.

In the case of this example, the stabilizer bar 204 is positioned above the vehicle body side member 212, so that the upright walls 214 rise upward from the vehicle body side member 212, respectively.
When the stabilizer bar 204 is disposed on the lower side of the vehicle body side member 212, the standing walls 214 are configured to stand downward from the vehicle body side member 212.

  The stabilizer bar bush 200 has a U-shaped cross-section corresponding to the holding portion 208 in the mounting bracket 206, and as shown in FIG. Part) 216 is provided in a U-shape, and this engagement protrusion 216 is engaged with an engagement groove 218 formed in a U-shape on the inner surface of the holding portion 208 of the mounting bracket 206.

The stabilizer bar bush 200 is provided with a cut 222 extending from the outer peripheral surface to the insertion hole 202, and the stabilizer bar bush 200 is perpendicular to the axis of the insertion hole 202 with respect to the stabilizer bar 204. It is designed to be elastically fitted.
The stabilizer bar bush 200 having a U-shaped cross section is inserted into the holding portion 208 from the opening 220 on the fixing portion 210 side and held by the holding portion 208 with respect to the mounting bracket 206.

  Incidentally, in recent years, the separation distance L of the stabilizer bar 204 from the vehicle body side member 212 may be set to be large. In this case, the portion of the stabilizer bar bush 200 between the stabilizer bar 204 and the vehicle body side member 212 is entirely made of rubber. In this case, the rubber thickness of the portion becomes too thick, and the support rigidity (spring rigidity) of the stabilizer bar bush 200 becomes too small.

Therefore, in order to prevent this, as shown in FIG. 13, a portion between the stabilizer bar 204 and the vehicle body side member 212, specifically, between the insertion hole 202 and the seating surface 228 on the vehicle body side member 212, For example, a hard and rigid resin block 224 is embedded.
That is, the stabilizer bar bush 200 is composed of a rubber bush body 226 and a resin block 224 that is entirely embedded in the bush body 226.
In this case, the rubber thickness between the insertion hole 202 and the seating surface 228 in the bush main body 226 can be maintained at an appropriate thickness by appropriately selecting the vertical dimension of the resin block 224 in FIG.

  In the stabilizer bar bush 200 shown in FIG. 13, a resin block 224 is molded in advance, and this is set in a cavity of a molding die of the bush main body 226. In this state, a rubber material is injected and the bush main body 226 is added. The resin block 224 is integrated and manufactured in the embedded state at the same time as the sulfur molding. In this case, the resin block 224 must be set in the mold every time the molding is performed. is there.

  Further, since the resin block 224 needs to be held and restrained at a predetermined position when the bushing body 226 is molded, the mold structure of the mold is inevitably complicated, and the number of products taken per mold is inevitably increased. For this reason, the problem that the manufacturing cost of the stabilizer bar bush 200 becomes high arises.

Patent Document 1 listed below discloses an elastic support device that improves this problem.
FIG. 15 shows a specific example of a stabilizer bar bush in the elastic support device.
In this example, a seating surface 228 seated on the vehicle body side member 212 is provided on the resin block 224, and the resin block 224 and the bush body 226 having the insertion hole 202 are integrated with the seating surface 228 exposed to the outside. Is.

  In the case of this example, the resin block 224 is set in the cavity of the mold, and the bush body 226 is vulcanized and molded at the same time as the resin block 224 is integrated. However, since the resin block 224 is not completely embedded in the bush body 226 here, and a part of the resin block 224 is exposed to the outside, the coupling recesses 232 and 234 are provided in the resin block 224, At the time of forming the bushing body 226, the connecting protrusions 236 and 238 are simultaneously formed on the bushing body 226 side so that they are embedded in the connecting recesses 232 and 234, so that the resin block 224 and the bushing body 226 are connected. They are connected and integrated.

  In the case of the stabilizer bar bush 240 shown in FIG. 15, it is relatively easy to hold the positioning of the resin block 224 in the cavity of the mold, and this is an improvement compared to the stabilizer bar bush 200 shown in FIGS. However, when the stabilizer bar bush 240 is molded, specifically, when the bush main body 226 is molded, it is necessary to set the pre-molded resin block 224 in the cavity. There is still a problem that the mold structure for maintaining the positioning or the mold disassembly structure for taking out the product after molding is still complicated.

Effects and effects of the invention

  As described above, in the past, the resin block was previously molded and set in a mold for the rubber bush body, and in that state, the bush body was molded and integrated with the resin block at the same time. On the other hand, in the present invention, the stabilizer bar bush is divided into a resin block and a rubber bush main body, each of which is molded separately, and they are attached and fixed to the vehicle body side member by a mounting bracket from the outside. is there.

Therefore, according to the present invention, when the rubber bush body is vulcanized, it is not necessary to set the resin block in a positioning state in the mold, and accordingly, the resin block is troublesome when the bush body is vulcanized. Can be eliminated, and the mold structure of the mold can be simplified.
In addition, it is possible to increase the number of the bush body formed by the forming die, thereby reducing the production cost of the stabilizer bar bush.

  By the way, if the resin block and the bush main body are separately molded in this way and assembled to the vehicle body side member via the mounting bracket, the resin block is attached when force is applied to the resin block from the stabilizer bar during vehicle travel. There is a risk of detachment from the bracket.

  Here, in the present invention, the resin block is provided with an engaging convex portion for mounting bracket, and the engaging convex portion is engaged with an engaging concave portion provided in the mounting bracket, so that the resin block is directly positioned on the mounting bracket. According to the present invention, the resin block is directly restrained and held by the mounting bracket in spite of the fact that the resin block and the bush main body are formed as separate molded products. Even when a force is applied to the resin block from the stabilizer bar during traveling of the vehicle, the resin block can be prevented from being detached from the mounting bracket.

According to the present invention, the engaging recess of the mounting bracket extends in a direction substantially perpendicular to the axis of the insertion hole in the bushing body, and the resin block as a separate member is engaged with the engaging convex portion of the mounting bracket. It is designed to be fixed in the axial direction of the insertion hole with respect to the mounting bracket by engaging with the joint recess.

Further, according to the present invention , the bush main body and the holding portion of the mounting bracket including the pair of standing walls standing up against each other in a direction away from the vehicle body side member and the curved connecting portion connecting the end portions thereof, The resin block is inserted into the holding portion through the opening on the side opposite to the connecting portion, and the engagement recess and the engagement projection are provided in a form extending in the insertion direction. By doing so, the resin block can be inserted into the holding portion of the mounting bracket, and at the same time, the engaging concave portion and the engaging convex portion can be engaged with each other in the axial direction of the insertion hole. Assembly with the resin block can be easily performed.

In the present invention, the engaging protrusions are provided on the outer surface of the bushing body so as to extend in the insertion direction. According to the present invention , the bushing body is also inserted into the holding part of the mounting bracket and simultaneously with the engaging protrusions. With the engagement between the portion and the engagement concave portion, the mounting bracket can be engaged in a direction perpendicular to the insertion direction, that is, in the axial direction of the insertion hole.
As a result, it is possible to satisfactorily prevent the bush body from being detached from the mounting bracket in the same direction (axial direction of the insertion hole).

In the present invention, the bush main body and the resin block, which are respectively formed as separate molded products, are elastically engaged by the latching convex portion and the latching concave portion provided in each, and in this way , When the bush body and resin block are inserted and held in the mounting bracket, they can be assembled with each other in advance, so that the assembly of the bush body, resin block and mounting bracket is further improved. Can be

By the way, if the entire surface of the bush body on the resin block side and the surface of the corresponding resin block on the bush body side are flat surfaces extending in a direction perpendicular to the axis of the insertion hole, the stabilizer bar can be When displaced in the direction approaching the member, the portion directly below the insertion hole of the rubber bush body through which the stabilizer bar is inserted (when the stabilizer bar is arranged above the vehicle body side member) or directly above the insertion hole The portion (when the stabilizer bar is disposed below the vehicle body side member) is in a state of being strongly sandwiched between the stabilizer bar and the resin block.
Moreover, since the rubber thickness of the part directly below or just above the stabilizer bar is thinner than the other parts, the same part is strongly pressed by the clamping pressure between the stabilizer bar and the resin block, and there is a large compressive strain and stress on it. appear.
As a result, cracks are likely to occur in the same portion, which may reduce durability.

Those of claim 2 wherein, while forming surface of the resin block side of the bushing body, i.e. the lower surface or the upper surface of the resin block side of the bushing body, a convex curved surface which is curved along the periphery of the at least partially the insertion hole, The corresponding surface on the resin block side is a concave curved surface corresponding to the convex curved surface, and the convex curved surface and the concave curved surface are fitted to each other. In this way, the displacement of the stabilizer bar is reduced. The accompanying strain and stress are distributed around the insertion hole without intensively acting on the part directly below or directly above the stabilizer bar, and large local strains and stresses are avoided immediately below or directly above the insertion hole. Can do.

Thereby, the problem of the crack generation by the large local distortion and stress can be solved, and the durable life of the bush main body can be effectively extended.

In this embodiment, the lower surface of the bushing body 24 is made of resin substantially along the periphery of the insertion hole 42 except for the left and right ends, that is, one end and the other end perpendicular to the axis of the insertion hole 42. The convex surface 70 is curved toward the block 26 side, and the corresponding surface of the resin block 26 is formed as a concave curved surface 72 corresponding to the convex curved surface 70 so that the convex curved surface 70 and the concave curved surface 72 are fitted to each other. This is an example in which the bush body 24 and the resin block 26 are combined.
Here, each of the convex curved surface 70 and the concave curved surface 72 is an arc surface that is centered on the axial center of the insertion hole 42 and forms a part of a concentric circle with the circumference of the insertion hole 42.

  As a result, the strain and stress associated with the displacement of the stabilizer bar 10 do not concentrate on the portion immediately below the stabilizer bar 10 (portion C in FIG. 12B), and the area around the insertion hole 42 (FIG. 12A). It is possible to avoid the occurrence of large local strain and stress in the portion immediately below the insertion hole 42.

In the case shown in FIG. 12B, if the lower surface of the bushing body 24 is simply protruded toward the resin block 26 and the surface of the protruding portion is a convex curved surface 70, the spring constant in the vertical direction is It will be lower.
Therefore, in the embodiment shown in FIG. 12A, that is, in the embodiment shown in FIG. 11, the positions of both end portions of the bushing body 24 in the left-right direction in the drawing are changed upward in the drawing so as to ensure the required spring rigidity in the vertical direction. I have to.
That is, by making the lower surface of the bush body 24 a downward convex curved surface 70, durability can be improved while ensuring required spring rigidity in the vertical direction.
