出願人は提案した。(Background Art) As one of the independent suspension systems for vehicles, there is a double link suspension in which a nut that supports a wheel is supported by one upper arm forming a transverse link and one or two lower arms. The applicant has proposed a double link suspension with a trailing arm (hereinafter abbreviated as TWL suspension) in which the following is supported by a trailing arm.

効長を長くすると、アツパアームの揺動確保のた
めのスペースが大きくなるという問題があつた。 In this type of TWL suspension, an unequal length arm is constructed in which the upper arm is shorter than the lower arm in order to give a camber change. Since the camber change tends to be excessive, an appropriate camber change cannot be obtained, and on the other hand, if the effective length is made longer, there is a problem that the space for ensuring the rocking of the upper arm becomes larger.

The lower part is connected to the lower part at a joint 10 so as to be relatively rotatable. That is, a bearing part 4 whose axis is parallel to the spindle 3 is provided protruding from the upper part of the lower nutacle 2 behind the spindle 3, and a bracket 5 is provided protruding from the inner surface. A shaft 6 is provided on the

A bearing part 18 whose axes are perpendicular to each other is provided, and a shaft part 25 bent at the outer end of the upper arm 24 is rotatably fitted into the bearing part 18 from the rear. Here, the length of the atsupah arm 24 is the shortest, and the length of the front lower arm 21 is the shortest.
is the second longest, and the rear lower arm 22 is the longest.

の車輪の上下動最大ストロークを大きくできる。 In this way, in the TWL suspension, the nut 1 is divided into two parts, upper and lower, and the joint 10, which is relatively rotatable, is provided in the divided part.
Since the lower knuckle 2 is fixed to the trailing arm 27, the angle of the upper knuckle 12 relative to the trailing arm 27 can be freely changed. According to such a structure, when the knuckle 1 strokes upward, the upper knuckle 12 inclines greatly with respect to the trailing arm 27 as shown in FIG. 2, thereby suppressing the rise of the pivot point A, The maximum vertical stroke S1 of the pivot point A can be made as small as possible. Therefore, according to the structure of this embodiment, the S1
can be made smaller, so that the maximum stroke S2 of the center point B of the joint 10 can be increased accordingly. As described above, according to the structure of this embodiment, the maximum vertical stroke of the spindle 3, that is, the wheel (not shown) can be made larger than that of the conventional knuckle even if an upper arm having the same effective length is used.

きるので、省スペースの面でも有利である。 As can be seen from this, the maximum stroke S1 of the pivot point A required to obtain an appropriate camber change can be made smaller than when using a conventional integrated knuckle. Since the effective length of the upper arm 24, that is, the distance L between the pivot point A and the pivot point C toward the vehicle body, can be shortened, it is also advantageous in terms of space saving.

パナツクル42を後傾させて連結する。 FIG. 3 shows a second embodiment. In this embodiment, a joint 40 similar to that described above is provided at the upper part of the lower knuckle 32 in front of the spindle 33, and the upper knuckle 42 is connected by tilting backward.

有効長Lもより短くなる。 In this way, the joint 40 connects the lower knuckle 32 and the upper knuckle 42 in a relatively rotatable manner.
is placed above the front of the spindle 33, and the atsupaknuckle 42 is assembled with it tilted backwards, so that the center point B of the joint 40 swings forward and upward so as to involve the atsupaknuckle 42, which is tilted backwards, as shown by the imaginary line in FIG. do. As a result, a pulling effect is exerted on the pivot point A between the upper arm 54 and the upper knuckle 42, so that the maximum stroke S1 of this pivot point A does not become very large. Therefore, the effective length L of the upper arm 54 also becomes shorter.

85を回転自在に嵌合する。 FIG. 5 shows a third embodiment. In this embodiment, a joint 70 is provided concentrically with the spindle 63 of the lower knuckle 62, and a damper bracket 69 is extended forward from the front lower part of the lower knuckle 62. The lower part of the damper 29 is connected to the front end of the damper 69. Further, the shaft portion 85 at the outer end of the upper arm 84 is rotatably fitted into the bearing portion 78 at the upper portion of the upper arm nut 72 from the front.

スペース上有利となる。 By arranging the joint 70 concentrically with the spindle 63 in this way, the mounting part of the spindle 63 can also be used as the bearing part of the joint 70.
Processing can be omitted, and processing costs can therefore be reduced. Furthermore, by extending the damper bracket 69 forward, the damper 29 can be placed closer to the front end pivot point D of the trailing arm 27, so the expansion and contraction stroke of the damper 29 can be shortened, and the overall length of the damper 29 can therefore be shortened. This is advantageous in terms of space saving.

Since it can also be used as a 9-mounting part, the damper bracket can be eliminated and processing costs can be reduced.

実用性に富む。(Effects of the Invention) As described above, according to the TWL suspension of the present invention, the knuckle is divided into upper and lower parts, and a freely rotatable joint is provided in the divided part, so that the vertical movement stroke of the wheel is ensured by rotation at the joint. At the same time, it is possible to shorten the effective length of the atsupah arm compared to the conventional one, so it is possible to obtain an appropriate camber change, and it is also effective in terms of space saving.
Full of practicality.
