Description

  The present invention relates to a stabilizer bar mounting device, and more particularly to a stabilizer bar mounting device for mounting a stabilizer bar to a vehicle body.

A vehicle is usually provided with a stabilizer bar for maintaining the vehicle posture properly. Both ends of the stabilizer bar are connected to a wheel support member such as a lower arm to which each of the left and right wheels is attached. As a result, when a vertical force is applied to one of the left and right wheels, the force is transmitted to the other wheel, and the posture of the vehicle is maintained appropriately. The stabilizer bar is generally connected to the vehicle body at an intermediate portion between both ends. At this time, in many cases, as proposed in Patent Document 1 and Patent Document 2, for example, a rubber bush or the like is fixed to the vehicle body by a housing or the like through an elastic material for suppressing vibration transmission.

  However, in the stabilizer bar mounting apparatus proposed in the above-mentioned patent document, the bracket for mounting the stabilizer bar to the vehicle body must be fastened with a fastening member such as a bolt from the lower side of the vehicle body. For this reason, it is difficult for an operator to attach / detach the stabilizer bar to / from the vehicle body. On the other hand, as described above, when a vertical force is applied to one of the left and right wheels, the stabilizer bar transmits the force to the other wheel. For this reason, it is necessary to firmly fix the stabilizer bar in the vertical direction with respect to the vehicle body.

  This invention is made | formed in view of such a subject, The objective is to make the attachment or detachment operation | work of a stabilizer bar easy, ensuring the firm fixation of the stabilizer bar to a to-be-attached surface.

  In order to solve the above-described problems, a stabilizer bar mounting device according to an aspect of the present invention is provided when a pair of inner surfaces are provided side by side so as to contact the inner surface of the bracket and a bracket that is tapered on the opening side. And a first member and a second member which are tapered on the opening side of the bracket on a pair of outer surfaces arranged side by side. With the stabilizer bar arranged between the first member and the second member, the opening side is pressed toward the mounting surface from the initial position where the bracket contacts the first member and the second member arranged side by side. Thus, a pressing force from the inner surface of the bracket to the outer surface formed by the first member and the second member acts, and the first member and the second member sandwich and support the stabilizer bar.

  In places where the stabilizer bar is attached to the surface to be attached, a substantially vertical force is normally applied to the stabilizer bar, for example, when the vehicle travels on an uneven road surface. On the other hand, the worker can easily perform the work of attaching and detaching the bracket from the lateral direction. According to this aspect, the direction in which the stabilizer bar is clamped can be different from the direction in which the bracket bar is pressed. For this reason, it is possible to make it easy to attach and detach the stabilizer bar and to firmly fix the stabilizer bar in the direction in which the force is applied.

  The first member may include a first outer member having a tapered outer surface, and a first elastic member that can be expanded and contracted provided between the first outer member and the stabilizer bar. The second member may include a second outer member having a tapered outer surface, and a second elastic member that can be expanded and contracted provided between the second outer member and the stabilizer bar.

  According to this aspect, when the bracket is pressed, a pressing force from the inner surface of the bracket to the outer surface formed by the first member and the second member acts, and the first elastic member and the second elastic member are compressed. Can do. For this reason, the interference which compresses a 1st elastic member and a 2nd elastic member can be ensured, and a stabilizer bar can be fixed firmly.

  The first elastic member may integrally couple the first outer member and the stabilizer bar, and the second elastic member may integrally couple the second outer member and the stabilizer bar. According to this aspect, the stabilizer bar, the first outer member, the second outer member, the first elastic member, and the second elastic member can be handled integrally, and the attaching / detaching work of the stabilizer bar can be facilitated. .

  Each of the first outer member and the second outer member may have a pressing portion that presses the attached surface by attaching the bracket to the attached surface. A third elastic member that can expand and contract in a substantially horizontal direction may be provided between each pressing portion of the first outer member and the second outer member and the attached surface. According to this aspect, rattling between the bracket, the first outer member, and the second outer member due to the bracket being attached to the attachment surface can be suppressed.

  The first member and the second member are each formed with a pair of contact surfaces that face each other with a gap when the bracket is in the initial position and contact the bracket until the bracket is pressed against the mounting surface. May be. According to this aspect, the stabilizer bar can be clamped between the first member and the second member with the desired force by predetermining the distance between the pair of contact surfaces when the bracket is in the initial position. it can.

  According to the stabilizer bar mounting device of the present invention, the stabilizer bar can be easily attached and detached while ensuring the firm fixation of the stabilizer bar to the mounting surface in the vertical direction.

  Hereinafter, embodiments of the present invention (hereinafter referred to as “embodiments”) will be described in detail with reference to the drawings.

  FIG. 1 is a view showing a configuration of a stabilizer bar mounting device 100 according to the present embodiment and its surroundings. This figure is a perspective view of the front side of the vehicle body. The arrow shown on the left side of the figure will be described below as the vehicle front direction.

  The vehicle body includes a lower frame 10, a stabilizer bar 22, a stabilizer bar mounting device 100, a lower arm 12, and the like. The lower frame 10 functions as a vehicle body main body that supports each component in the vehicle body, and functions as an unsprung body that supports each of the components that are arranged under the so-called unsprung structure in conjunction with the lower portion of the suspension. The lower frame 10 has a mounted surface 66 as a vertical surface facing the front direction of the vehicle.

  The stabilizer bar mounting apparatus 100 includes a bracket 40, a first outer unit 70, a second outer unit 72, and the like. The stabilizer bar mounting device 100 is mounted at two locations near the left and right ends of the mounting surface 66. The bracket 40 is fixed to the mounting surface 66 by fastening the bolt 60 from the horizontal direction. The first outer unit 70 and the second outer unit 72 are clamped and fixed between the bracket 40 and the mounted surface 66 when the bracket 40 is pressed against the mounted surface 66 in the horizontal direction. Thereby, the 1st outer unit 70 and the 2nd outer unit 72 hold and support the stabilizer bar 22. Accordingly, the first outer unit 70 and the second outer unit 72 function as a first member and a second member that sandwich and support the stabilizer bar 22, respectively.

  The stabilizer bar 22 is a shaft-shaped member having a circular cross section, and is formed extending in the left-right direction of the vehicle. The first outer unit 70 and the second outer unit 72 support the stabilizer bar 22 by sandwiching it in the vertical direction. Therefore, the first outer unit 70 and the second outer unit 72 function as stabilizer bar support means that sandwich and support the stabilizer bar 22 in the vertical direction.

  The stabilizer bar 22 is formed in a U-shape bent toward the rear of the vehicle in the vicinity of each of the left and right wheels. A pair of lower arms 12 is provided on the left and right sides of the vehicle body corresponding to a pair of wheels provided on the left and right. The lower arm 12 is attached to a lower arm support member 14 provided on each of the left and right side surfaces of the lower frame 10 so as to be rotatable about a rotation shaft provided on the lower arm support member 14. As a result, if the lower arm 12 is disposed on the left side of the vehicle body, the left front end portion can swing in the substantially vertical direction, and if the lower arm 12 is disposed on the right side of the vehicle body, the right front end portion can swing. Both ends of the U-shaped stabilizer bar 22 are supported via the connecting member 16 between the tip of the lower arm 12 and the rotation shaft.

  A wheel is attached to the tip of the lower arm 12 via a knuckle or the like. The wheels are also supported on the upper part of the vehicle body via the suspension. When one of the left and right wheels rides on a convex road surface, the lower arm 12 swings upward about the rotation axis of the lower arm support member 14. For this reason, one end of the stabilizer bar 22 fixed to the lower arm 12 is also lifted upward. Since the stabilizer bar 22 is formed in a U-shape, when one end of the stabilizer bar 22 is lifted, torque is applied to a portion of the stabilizer bar 22 that extends in the left-right direction of the vehicle. This torque is transmitted to the other wheel side, and a force is applied to lift up the portion where the stabilizer bar 22 near the other wheel is fixed. For this reason, the lower arm 12 on the other wheel side is also lifted upward about the rotation axis of the lower arm support member 14. Thus, since the stabilizer bar 22 transmits the movement of one lower arm 12 to the other lower arm 12, only one of the left and right lower arms 12 is restrained from being greatly rotated, and only one of the left and right wheels is greatly raised. Lifting in the direction is suppressed. This suppresses the vehicle from tilting when one of the wheels rides on the convex portion while the vehicle is running.

  In this way, both ends of the stabilizer bar 22 are fixed to the lower arm 12 that rotates in the vertical direction, so that a force is applied in the vertical direction to the stabilizer bar mounting device 100 in which the stabilizer bar 22 is fixed to the lower frame 10. It is done. For this reason, when the stabilizer bar 22 is attached to the lower frame 10, it is required to be firmly fixed in the vertical direction.

  In the stabilizer bar mounting apparatus 100 according to the present embodiment, FIG. 3A is a diagram showing a state in which the bracket 40 is in an initial position where it abuts against the first outer unit 70 and the second outer unit 72 arranged side by side. 3B is a diagram illustrating a state in which the first contact surface 26e and the third contact surface 28e, and the second contact surface 26f and the fourth contact surface 28f are in contact with each other. (C) is a figure which shows the state in which the bracket 40 was attached to the to-be-attached surface 66. FIG.

  When an operator fixes the stabilizer bar 22 to the lower frame 10, first, the third elastic member 34 of the first outer unit 70 and the second outer unit 72 that are integrally coupled to the stabilizer bar 22 is horizontally moved backward. It is made to contact | abut to the to-be-attached surface 66 in a direction. Next, the bracket 40 is brought into contact with the first inclined outer surface 26a of the first outer member 26 and the first inclined inner surface 46, and the second inclined outer surface 28a and the second inclined inner surface 48 of the second outer member 28 are in contact with each other. In the same way, press it horizontally toward the rear. Accordingly, as shown in FIG. 3A, the bracket 40 is first arranged at an initial position where it abuts against the first outer unit 70 and the second outer unit 72 that are arranged side by side. In this state, between the first contact surface 26e of the first outer member 26 and the third contact surface 28e of the second outer member 28, and between the second contact surface 26f of the first outer member 26 and the second outer surface. The distance provided between each member 28 and the fourth contact surface 28f is hardly reduced. In a state where the bracket 40 is disposed at the initial position, the bolt 60 is inserted into the first bolt hole 52 and the second bolt hole 54, respectively, and tightening to the mounting surface 66 is started.

  When the bolt 60 is tightened from the state shown in FIG. 3A in which the bracket 40 is in the initial position, the first mounting portion 42 and the second mounting portion 44 are pressed toward the lower frame 10, and the bracket 40 is gradually moved. Next, it moves in the direction of the mounting surface 66 of the lower frame 10. As the bracket 40 moves, the first inclined inner surface 46 of the bracket 40 and the first inclined outer surface 26a of the first outer member 26, and the second inclined inner surface 48 of the bracket 40 and the second inclined outer surface 28a of the second outer member 28. And slide. At this time, the movement of the first outer member 26 and the second outer member 28 in the direction of the lower frame 10 is restricted because the third elastic member 34 abuts the attached surface 66. For this reason, the pressing force from the inner surface of the bracket 40 to the outer surface formed by the first outer unit 70 and the second outer unit 72 acts. Specifically, a downward force is applied to the first inclined outer surface 26a, and an upward force is applied to the second inclined outer surface 28a. As a result, the first outer member 26 moves downward, and the second outer member 28 moves upward.

  As the first outer member 26 moves downward and the second outer member 28 moves upward, the first elastic member 30 provided between the first outer member 26 and the stabilizer bar 22, and the second The second elastic member 32 provided between the outer member 28 and the stabilizer bar 22 is compressed in the vertical direction. As a result, the force for clamping the stabilizer bar 22 by the first elastic member 30 and the second elastic member 32 gradually increases.

  In addition, the 1st elastic member 30 and the 2nd elastic member 32 are expanded in the direction different from a compression direction in the vicinity of the stabilizer bar 22 by being compressed in the perpendicular direction. The concave portion 30a and the concave portion 32a are restrained from contacting each other when the first elastic member 30 and the second elastic member 32 cause such swelling.

  Further, as the first outer member 26 moves downward and the second outer member 28 moves upward, the first contact member 26e and the third contact surface 28e, and the second contact member. The space between the surface 26f and the fourth contact surface 28f is gradually narrowed. When the bolt 60 is further tightened, the bolt 40 is fastened to the mounting surface 66 by the bolt 60, that is, the surface of the first mounting portion 42 and the second mounting portion 44 on the mounting surface 66 side and the mounting surface 66. 3b, as shown in FIG. 3B, the first contact surface 26e and the third contact surface 28e, and the second contact surface 26f and the fourth contact surface. 28f abut against each other. As a result, the first outer member and the second outer member are fixed to each other in the vertical direction.

  The first contact surface 26e and the third contact surface 28e, the second contact surface 26f and the fourth contact surface 28f are in contact with each other, and the bolt 60 is held while the curved surface 26c and the curved surface 28c are in contact with the curved surface 50. When further tightened, the first outer member 26 and the second outer member 28 are pressed against the attachment surface 66 together with the bracket 40. As a result, as shown in FIG. 3C, the third elastic member 34 is pressed against the attached surface 66 by the pressing surface 26b and the pressing surface 28b and compressed.

  As described above, by providing the third elastic member 34 between the first outer member 26 and the second outer member 28 and the attached surface 66, the first contact is made when the bracket 40 is attached to the attached surface 66. Even when the contact surface 26e and the third contact surface 28e and the second contact surface 26f and the fourth contact surface 28f contact each other, the bracket 40 can be further pushed in the vehicle horizontal direction. Thereby, rattling between the bracket 40 and the first outer member 26 and the second outer member 28 can be suppressed.

  As described above, the stabilizer bar mounting device 100 according to the present embodiment secures the interference for compressing the first elastic member 30 and the second elastic member 32 in the substantially vertical direction, and compresses this to stabilize the stabilizer bar 22. Therefore, the stabilizer bar 22 can be firmly fixed in the substantially vertical direction. Further, according to the stabilizer bar mounting device 100 in the present embodiment, the stabilizer bar 22 can be sandwiched and supported in the substantially vertical direction by pressing the bracket 40 against the vehicle body in the substantially horizontal direction. For this reason, it is possible to make it easy to attach and detach the stabilizer bar 22 and to firmly fix the stabilizer bar 22 in a substantially vertical direction, which is a direction in which a force is applied.

  The present invention is not limited to the above-described embodiments, and an appropriate combination of the elements of each embodiment is also effective as an embodiment of the present invention. Various modifications such as design changes can be added to each embodiment based on the knowledge of those skilled in the art, and embodiments to which such modifications are added can also be included in the scope of the present invention. Here are some examples.

As a result, the stabilizer bar 22 provided on the rear side of the vehicle can also achieve both easy attachment / detachment work and firm fixation in the substantially vertical direction.

  The first elastic member 30 and the second elastic member 32 may not be integrally coupled to the stabilizer bar 22, and may be detachable from the stabilizer bar 22. Accordingly, even when the first elastic member 30 or the second elastic member 32 needs to be replaced due to deterioration, for example, it is not necessary to replace it together with the stabilizer bar 22, so that the replacement work can be easily performed. And the cost of replacement parts can be reduced.

  The inner peripheral surface 26d of the first outer member 26 and the inner peripheral surface 28d of the second outer member 28 do not have to be arc-shaped, and the outer peripheral surfaces of the first elastic member 30 and the second elastic member 32 are also arc-shaped. It does not have to be. These shapes may be rectangular or elliptical arc shapes, for example, and various shapes may be selected according to the force with which the stabilizer bar 22 is clamped.
