Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a torque rod adjuster structure in which one end is attached to the frame side of the vehicle body and the other end is attached to the axle side. Particularly, the adjustment position of the torque rod is easily adjusted and the adjustment allowance can be easily read. The present invention relates to a torque rod adjuster device for a vehicle.

[0002]

[Prior art]

 In automobile suspensions, a torque rod is provided between the frame side and axle side of the vehicle body to prevent axle wind-up.

A mounting structure of the torque rod is disclosed in, for example, Japanese Utility Model Laid-Open No. 1-148908. However, since the structure of the torque rod disclosed in this publication is fixed, the length of the torque rod cannot be adjusted, and consequently the variation in the length direction of the torque rod cannot be adjusted.

[0006] Therefore, there has been proposed a device capable of adjusting the length as shown in FIGS. 6 and 7.

In FIG. 6, reference numeral 50 denotes a leaf spring, and a bracket 52 is fixed to an axle 51 to which the leaf spring 50 is attached, and one end portion of a torque rod 53 is attached to the bracket 52 so as to be adjustable as will be described later. It has been done. The other end of the torque rod 53 is attached to a frame (not shown) by a bolt 57 via a rubber 54, washers 55, 56 and the like.

At one end 60 of the torque rod 53, a through hole is formed in a direction perpendicular to the axial direction, and an annular rubber 61 and an eccentric cam 62 are inserted into this through hole, and a spring washer 63. It can be freely adjustably attached to the bracket 52 with a bolt 64 and a nut 65 via.

The bracket 52 has a pair of flanges, and one flange 68 is provided with plate-shaped guide plates 66 and 67 as shown in FIG. The eccentric cam 62 is provided between the guide plates 66 and 67.

Therefore, in FIG. 7, when the eccentric cam 62 is rotated by a predetermined amount, the guide plates 66 and 67 are fixed to the axle 5, so that the eccentric amount causes the torque rod 53 to move in the direction indicated by the arrow a. Will be adjusted. After the adjustment, tighten the nut 65 to fix it.

[0009]

[Problems to be solved by the device]

 The above torque rod mounting structure also has an eccentric cam, so that the rod can be adjusted in the longitudinal direction.

However, due to the use of the eccentric cam, there are various problems. For example, the torque rod 53 receives a lateral force in FIG. 7, so that the contact between the cam surface and the guide plates 66 and 67 is point contact, resulting in a large surface pressure and a large amount of wear. If this were to prevent this wear, another problem would arise: the cam surface would have to be large. Also, a large rotating torque is required to adjust the eccentric cam 62 by rotating it, and the workability is poor.

Further, as understood from FIG. 7, when the eccentric cam 62 is rotated, the axis O of the end portion 60 of the torque rod 53 is displaced in the vertical direction, which causes a problem that the geometry is deformed.

[0012] In terms of practicality, it is inconvenient because the adjustment allowance is unknown.

In view of such a problem, the present invention has an object to provide an adjuster structure of a torque rod which has little wear, has good workability, has no change in geometry, and can easily confirm even an adjustment allowance. And

[0014]

[Means for Solving the Problems]

 Therefore, in this invention, in the adjuster structure of the torque rod in which one end is attached to the frame side of the vehicle body and the other end is attached to the axle side, a bracket fixed to the frame side or the axle side, and a vertical guide guided by the bracket. And an adjuster plate that slides in the direction to adjust the length of the torque rod, and the bracket has a horizontally long slot through which the connecting shaft of the torque rod is inserted. The plate is U-shaped in cross section, and long flanges are formed in the flanges on both sides of the plate in the diagonal direction through which the connecting shaft of the torque rod is inserted. The structure is provided with a scale below the long hole to achieve the above object.

[0015]

[Action]

 One end of the torque rod is attached to the frame side of the vehicle body, and the other end is attached to the same axle side. Either one end is attached to the frame side or axle side with the bracket and adjuster plate. At this time, the connecting shaft of the torque rod is inserted into the long hole of the bracket in the horizontal direction and the long hole of the adjuster plate. The connecting shaft is then positioned at the intersection of the two slots.

Therefore, when the adjuster plate is displaced in the vertical direction, the position of the intersection moves in the horizontal direction. That is, the connecting shaft moves horizontally to adjust the length of the torque rod. In this case, since the adjuster plate has a U-shaped cross section, both sides can be adjusted at the same time with one adjustment. Since a scale is provided below the horizontal elongated hole of the guide piece on the side surface of the bracket, it is sufficient to displace the scale up to the scale where the adjustment work can be easily performed.

After that, it may be fixed by a fixing means such as a bolt and a nut.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the torque rod is also attached to the frame side and the axle side. However, in the following, for convenience, the frame side is fixed and the axle side is fixed. An example in which the side is adjustably attached will be described.

Therefore, at the end of the torque rod located on the axle side, a connecting shaft is provided in a direction perpendicular to the rod, and a hole through which a bolt is inserted is formed at the center of the connecting shaft.

It is.

The bracket 1 fixed to the axle side is composed of a web portion 2 and flange portions 3 and 3, as shown in FIG. 1, and the web portion 2 is fixed to the axle. Then, a connecting shaft of a torque rod (not shown) is inserted between the flange portions 3 and 3.

Adjuster guides 4, 4 are fixed to the outer surface of the flange portion 3 of the bracket 1, respectively. A pair of guide pieces 6, 6 are integrally formed on the adjuster guide 4 with a predetermined space H therebetween.

The web portion 5 of the adjuster guide 4 is formed with a long hole 7 which is long in the horizontal direction, and the scale S shown in FIGS. 3 and 4 is provided below the long hole 7.

Further, since the connecting shaft of the torque rod is inserted into the long hole 7, the flange portions 3, 3 of the bracket 1 are also formed with the long hole 8 aligned with the long hole 7.

As shown in FIG. 2, the adjuster plate 10 guided between the guide pieces 6 and 6 of the adjuster guides 4 and 4 has a U-shaped cross section, and both sides of the adjuster plate 10 are flange portions 11, 11, and the flange portions 11, 11 are set by the guide pieces 6, 6. Each of these flange portions 11, 11 is formed with an elongated hole 12 into which the connecting shaft of the torque rod is inserted, and the elongated hole 12 is inclined by approximately 45 degrees from the horizontal plane.

Next, the operation of the above-described embodiment will be described. The web portion 2 of the bracket 1 is brought into contact with the axle and is fixed by, for example, a bolt. Then, the flange portions 11, 11 of the adjuster plate 10 are positioned between the guide pieces 6, 6 and the connecting shafts are inserted into the elongated holes 7, 8, 12. Then, the torque rod extends from the connecting shaft between the flange portions 3 and 3 of the bracket 1 to the left in FIG. 1, for example.

At this time, assuming that the center of the long hole 12 of the adjuster plate 10 and the center of the long hole 7 of the adjuster guide 4 coincide with each other, as shown in FIG. The shaft, or torque rod, will be in the central position. Then, in order to adjust the length of the torque rod, if the adjuster plate 10 is hit down downward with a hammer M as shown in FIG. 1, for example, the adjuster plate 10 moves in the direction shown in FIG. 5 and the torque rod becomes longer. At this time, the adjuster plate 10 has a substantially U-shaped cross section, and the flange portions 11 and 11 hang down on both sides. Therefore, when the hammer M is pushed down, the flange portions 11 and 11 are at the same degree at the same time. Move down.

On the other hand, when the adjuster plate 10 is moved upward, it moves to X2 and becomes shorter.

In these cases, since the web S of the adjuster guide 4 is provided with the scale S, the adjustment allowance can be easily visually recognized.

When the adjuster plate 10 is moved in the vertical direction and the adjustment is completed in this way, as shown in FIG. 1, the elongated hole 7 of the adjuster guide 4, the elongated hole 12 of the adjuster plate 10, and the connecting shaft are connected. The bolt 20 is passed through, and the nut 23 is tightened and fixed through the flat washer 21 and the spring washer 22.

[0031]

[Effect of device]

 According to this invention, the adjuster structure of the torque rod attached between the axle and the frame is composed of the bracket and the adjuster plate, and the bracket fixed on the axle or the frame side is inserted in the horizontal direction through which the connecting shaft is inserted. Since the long hole and the diagonal hole in the adjuster plate are formed, when adjusting the length of the torque rod, it is only necessary to strike the adjuster plate with a tool such as a hammer, that is, to adjust the adjuster plate to the bracket. All you have to do is move it up and down. Therefore, it can be adjusted with a small work force.

Moreover, in this case, since the adjuster plate has a substantially U-shaped cross section and the flange portions are formed on both side portions, each flange portion simultaneously moves downward in the identification degree when it is pushed down, and You can adjust and move both sides. In addition, since the adjuster guide is provided with scales, the adjustment allowance can be easily viewed.

Further, an axial force acts on the torque rod, but in this case, since the bracket and the flange portion of the adjuster plate are in flat contact with each other, the surface pressure is small and the contact portion is not worn. small.

Furthermore, since the long hole formed in the bracket is in the horizontal direction, the geometry does not change when the torque rod is adjusted.
