本考案は回転および軸方向の摺動可能な自動車
用板ばねの目玉部からブツシユの抜出しを防止し
た自動車用板ばね装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a leaf spring device for an automobile that prevents a bush from being pulled out from the eye of a rotatable and axially slidable leaf spring for an automobile.

に略固定されている。 In the automobile leaf spring device, as shown in FIGS. 1a, b, and c, eyelets 2 and 3 are formed at both ends of a leaf spring 1. One of the eyeballs 2 is attached to a spring bracket 5 by a pin 4 passed therethrough, but here the eyeball 2 is substantially fixed in the axial direction of the pin 4 by the spring bracket 5.

自在である。 A pin 6 is also passed through the eyelet 3 and attached to the shackle 7, but in this case gaps 8 and 9 are provided between the side of the eyelet 3 and the side of the shackle 7. This part is pin 6
It can be slid in the axial direction. Of course, the highlight 2
and 3 are rotatable about pins 4 and 6, respectively.

びコスト面より問題があつた。 A bush is fitted into the eye, and the eye 3 portion of the bush 11 inserted into the eye 3 in this figure slides in the axial direction of the pin 6, so the bush 11 moves in the axial direction of the pin 6. Sometimes you can get out of the 3rd eyeball. In other words, in general, the center button of a leaf spring that can slide in the axial direction becomes attached to each other due to the moment of the center button caused by the lateral load p 1 or p 2 , which increases the surface pressure at the end of the pin and the button. Brushes remain on the pin. In other words, there is a possibility that the bush will come out. In this case, if p 1 ≈p 2 , there is a possibility that the bush will come out on either side, and therefore a means to prevent it from coming out in both directions is required. If the bushing is fixed to the spring body by welding to prevent it from coming off, the heat generated during welding will have a negative effect on the strength of the spring body. Furthermore, the use of screw fastening of the bushing or adhesion by flanging on both sides of the bushing poses problems in terms of productivity and cost.

車用板ばね装置である。 SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a leaf spring device for an automobile that prevents the bush from being pulled out from the eye of the automatic shaft leaf spring. That is, the present invention includes a leaf spring having an eye portion that is offset in the width direction with respect to the center in the width direction of the leaf spring, and a flange portion that is inserted into the eye portion and formed on the opposite side to the direction in which the eye portion is biased. This is an automotive leaf spring device consisting of a bushing.

In this figure, the bush 11 of the present invention is press-fitted into the eye 3 of the leaf spring 1, and the pin 6 is inserted into the eye. It is fitted. The bush 11 of the present invention has a flange 11 on the side of the notch 10.

の効果を得ることができる。 In Figures 2a and 3, if the moment applied to the bush 11 due to P 1 is Mp 1 , the moment due to p 2 is Mp 2 , and the moment due to W is Mw, then the moment applied to the bush 11 when a lateral load p 2 is applied in the direction without the notch is Moment M 2 = Mw−Mp 2
Mw and Mp 2 are canceled and Butsuyu can't slip between the pins. When a lateral load p 1 is applied to the notch side, the moment applied to the bush 11 is M 1 =
Since Mw+Mp is 1 , the moment is large, the surface pressure at the end is large, and the surface pressure between the pin 6 and the bushing 11 is large, so the pin 6 and the bushing 11 do not slip even if no anti-slip device is provided. On the other hand, since the surface pressure between the bush 11 and the leaf 12 is small, the leaf 12
may slip leaving the bush 11 on the pin 6, but since the bush 11 has a flange 11a, the leaf 12 will not leave the bush 11 and slip even when a lateral load p1 is applied. Therefore, the bushing is prevented from slipping out from the leaf spring centerpiece. Moreover, since the bush has a flange formed only on one side, it can be easily inserted into the eye area. Further, the same effect can be obtained by making the center part of the leaf spring offset in the width direction with respect to the center of the leaf spring in the width direction, as shown in FIG. 2b.

造でブツシユの抜出しが防止できるのである。 As explained above, in the present invention, the eye part is offset in the width direction of the leaf spring with respect to the center in the width direction of the leaf spring, and the flange of the bush is formed in the opposite direction to the direction in which the eye part is offset. The simple structure prevents the bush from being pulled out.
