Modes for Carrying Out the Invention

[0011] Hereinafter, the best mode for carrying out the present invention will be described in detail based on embodiments.

Embodiment

[0012] First, with reference to FIG. 1, the basic structure of the present invention will be described. This figure shows an outline of the axle 110 and the lateral rod 120 of the automobile 100. Tires 112 are attached to both ends of the axle (axle housing) 110, and the vehicle body 130 is supported by a spring 114 provided between the axle 110. The left end 122 of the lateral rod 120 is rotatably attached to the left end side of the axle 110, and the right end 124 is rotatably attached to a bracket 132 below the vehicle body 130. These structures are well-known.

[0013] In this state, in order to raise the vehicle height of the automobile, when the vehicle body 130 is pulled upward in the direction of arrow F as shown in Fig. (A) of the same figure, as shown in Fig. (B) of the same figure, since the right end 124 of the lateral rod 120 rises, the lateral rod 120 rotates about the left end 122. In the illustrated example, the angle between the axle 110 and the lateral rod 120 is θ1. Note that since the vehicle body 130 moves to the left in the figure, the spring 114 supporting the vehicle body 130 is inclined.

[0014] When the automobile 100 travels in such a state, the vehicle body 130 sways in the vertical direction and the horizontal direction (lateral direction). However, the vertical sway is absorbed by the spring 114, and the horizontal sway is absorbed by the lateral rod 120. However, the connecting portion between the lateral rod 120 and the vehicle body 130 is displaced while rotating as pointed out in the above-described background art. The horizontal sway of the vehicle body 130 becomes more prominent as the inclination angle θ1 of the lateral rod 120 with respect to the axle 110 increases, that is, as the lift-up height of the vehicle body 130 increases.

[0015] Therefore, in this embodiment, as shown in Fig. (C) of the same figure, a down bracket 200 as shown in Fig. 1 is attached between the right end 124 of the lateral rod 120 and the vehicle body 130, and the right end 124 of the lateral rod 120 is attached to this so as to be rotatable and slidable. Thereby, even when the height after the lift-up of the vehicle body 130 is about the same, the inclination angle θ2 (θ1 > θ2) of the lateral rod 120 with respect to the axle 110 becomes smaller, and the horizontal sway of the vehicle body 130 is reduced.

[0016] Next, with reference to FIGS. 2 and 3, the down bracket 200 will be described in detail. FIG. 2(A) shows a perspective view of the down bracket 200, and FIG. 2(B) shows the state during attachment. Further, FIG. 3 shows the state of assembly during attachment. In these figures, the down bracket 200 is box-shaped as a whole, with the front side and the bottom side open, and the cross-section orthogonal to the vertical direction in FIG. 2(A) is substantially C-shaped or substantially U-shaped. The back plate 210 is composed of an upper back plate 212 and a lower back plate 214, and an opening 216 is provided between them.

[0017] Side plates 220 and 230 are provided substantially in parallel at both ends of the back plate 210. These side plates 220 and 230 have different upper and lower intervals, and the interval becomes wider toward the lower part.

[0018] An upper plate 240 is provided across the side plates 220 and 230 at the upper part of the back plate 210. The upper plate 240 and the back plate 210 are substantially L-shaped when viewed from the side, and bolt and nut means 242 are provided at this part. The bolt and nut means 242 are for attaching the down bracket 200 to the vehicle body side bracket 132. Bolt and nut holes 222 and 232 for attaching to the vehicle body side bracket 132 by bolt and nut means 250 (see FIG. 3) are provided at the middle parts of the side plates 220 and 230. Bolt and nut long holes 224 and 234 for attaching the right end 124 of the lateral rod 120 by bolt and nut means 260 (see FIG. 3) are provided at the lower parts of the side plates 220 and 230. The bolt and nut holes 222 and 232 are connected by a circular pipe 246 so that the bolt 250 can penetrate. Further, a pair of regulating ribs 226 and 236 for regulating the movement of the bolt and nut means 260 are respectively provided in the bolt and nut long holes 224 and 234 so as to sandwich them.

[0019] Next, the bolt and nut means 250 and 260 will be described with reference to FIG. 3. For the bolt and nut means 250, the bolt 252 passes through the bolt and nut holes 222 and 232 of the side plates 220 and 230 and the circular pipe 246 from the bolt and nut hole 134 of the vehicle body side bracket 132 of the vehicle body 130 into which the upper part of the down bracket 200 is fitted, and is fastened with the nut 256. Note that leaf springs 254 or washers are attached as necessary. On the other hand, for the bolt and nut means 260, the bolt 262 passes through the leaf spring 264, the regulating plate 266, the bolt and nut long hole 224 of the side plate 220, the rotation hole 126 at the right end 124 of the lateral rod 120, the bolt and nut long hole 234 of the side plate 230, and the regulating plate 267, and is fastened with the nut 268. In the illustrated example, the regulating plate 267 and the nut 268 are integrally formed.

[0020] The down bracket 200 is attached to the vehicle body side bracket 132 by the bolt and nut means 242 and 250. Next, the right end 124 of the lateral rod 120 is attached to the down bracket 200 by the bolt and nut means 260. At this time, the regulating plate 266 rotates and abuts between the regulating ribs 226 and 236, so that the bolt 262 in the bolt and nut long hole 234 of the side plate 230 is positioned and fixed.

[0021] Next, the operation of this embodiment will be described. When the vehicle body 130 is lifted up, conventionally, as shown in FIG. 1(B), the inclination angle of the lateral rod 120 with respect to the axle 110 is θ1. In contrast, in this embodiment, since the down bracket 200 is provided between the lateral rod 120 and the vehicle body 130, as shown in FIG. 1(C), the inclination angle of the lateral rod 120 with respect to the axle 110 is θ2, and θ1 > θ2 with respect to the angle θ1 in the background art. FIG. 4(A) shows this state. Conventionally, the lateral rod 120 at the angle θ1 shown by the dotted line, according to this embodiment, becomes the angle θ2. FIG. 4(B) shows an example when the amount of vehicle body lift is reduced. In this way, by providing the down bracket 200 between the vehicle body side and the lateral rod side, the inclination of the lateral rod 120 with respect to the axle 110 is reduced, and with a simple configuration, the lateral sway of the vehicle body can be well suppressed.

[0022] <Other Embodiments> There are numerous embodiments of the present invention, and various modifications can be made based on the above disclosure. For example, the attachment structure of the down bracket 200 and the lateral rod 120 shown in the above embodiment, and the attachment structure of the vehicle body side bracket 132 of the vehicle body 130 are all examples, and can be appropriately changed according to the structure of the right end 124 of the lateral rod 120 and the vehicle body side bracket 132.

Industrial Applicability

[0023] According to the present invention, by providing a down bracket between the vehicle body side and the lateral rod side, the inclination of the lateral rod with respect to the axle is reduced, and with a simple configuration, the lateral sway of the vehicle body can be well suppressed, which is suitable for increasing the vehicle height of vehicles such as Land Cruisers.
