Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vehicle suspension KIIL, l? The present invention relates to a vehicle suspension that is equipped with a so-called strut, which is a cylindrical member whose one end is fixed to a wheel support member, and which includes a shock absorber that is supported by a piston rod or a vehicle body.

Generally, the body of a car is mounted on 11 wheels via a suspension, but this suspension can be roughly divided into table-shaft suspension type and independent S-ride type.

The suspension system called Chapman type belongs to the 4JK sparrow's independent m system. As shown in Fig. 1, this Chugman lid suspension 1 is a modified example of a suspension board suspension, and is provided with a strut 3 with a built-in shock absorber 2.
A cylindrical member 5 of a -1 mmtrE strand 3 is fixed to a spindle 7 of a wheel A.

In the same figure, TC4 is shown in which the strut J is almost coaxial with the coil screw ring and integrated into the tic. Ii! There is one in which the coil spring gear and sound are installed separately and in parallel.

By the way, the shock absorber 2t is stored in the cylinder member 5 yen of the strut 3, lJ! 1 added cylinder a and this ring - 1a circle can be slid freely! An orifice (not shown) tf & ff7t (piston Jl) which communicates with both the upper and lower '1M 't + Rsk piston Jl) and the piston rod 2c attached to this piston rod bK and slidably protruding from the upper end of the liI outside 't' S It consists of
#The upper end of the rod 2c is v-shaped so that it is attached to the vehicle body 2 via the elastic body 10t. - 10,000, that car body? A bumper rubber//p is inserted into the rod 20 on the side, and when the single wheel and the vehicle body 9 are strongly displaced in the approaching direction, the bumper rubber//l is inserted into the cylindrical member. It is designed to come into contact with the upper end of S to finally regulate the displacement.

By the way, the cylindrical member S of the strut J is connected to the spindle V.
(c) If the absorber λ is welded and cannot be separated, and the absorber λ, which is detachably attached to the spindle 7 by means of the cylindrical member S bolt, etc., breaks down, as shown in the same figure. , the strut can be separated from the spindle 7 by removing the bolt tatllitv, the bumper rubber attached to the upper end of the ms member//f receiver is equipped with a member dt, a bearing IS, a seal member Camp for fixing /4' /4
L1 is bonded to the above wires by bath bonding, for example, by seam bath bonding which does not involve a high temperature rise, so that they are fixed together.

By the way, the Shock Apunno (J's Rod 2oI)
Ii, Horse 2 As shown in Figure 2, the cylinder member srv is rotatably and slidably supported via a bearing/J at the upper end,
Furthermore, Vt is set so that the sealing member 16 performs a seal 1 between the rod rod C and the cylinder member 5. Therefore, the bearing 15. A means 4B for fixing the seal member 16 to the cylindrical member j side is required.As this fixing means, a bearing ljt is placed on the upper end of the ring 1a of the shock absorber λ, and the upper gHc' of the armpit bearing 15 is mounted. *
A sealing member 14 is disposed through the spacer 15, and the sealing member 15 is pressed between the cap 1 and the cylinder λa. It is intended to be supported and fixed in between.

However, in such a conventional strut 3,
Cap/StWlN material StC@ has become worn, so the workability is poor and rawll1lE*! The problem is that the rate decreases.

Therefore, as a way to improve such conventional problems, it is possible to stop welding the cap to the cylindrical member by welding it, but instead of using the ms1 layer, it is possible to simply fix the camp cylindrical member 1ζ with screws, etc. This will instead lead to a further decline in production efficiency. Since the rounded cap is simply fitted onto the cylindrical member, it is necessary to support and fix the bearing and the seal member to the cylindrical member by other means and simple means.

Based on this actual situation, the present invention forms a plurality of convex portions that protrude inward around the upper end of the bearing of the cylindrical member, and fixes the bearing between the convex portion and the upper end of the cylinder of the shock absorber. Along with.

A plurality of crimped portions are formed at the upper end of the cylindrical member by bending the upper edge of the cylindrical member inward, and the MJ between the crimped portions and the convex portion is
Fix the K seal member. Therefore, the convex portion can be easily formed by embossing or the like, and the caulking portion can also be formed by simply bending the upper edge of the cylindrical member, so that the bearing and the sealing member can be supported by simple means.
Can be fixed.

One drawback is that the present invention does not use the conventional cap assembly, so the number of parts can be reduced.Furthermore, 11% of the adhesion work for fixing the cap to the cylindrical member can be omitted, which improves production efficiency. I can do it.

j! ! Furthermore, since there is no bath-coated strip, there is no thermal effect on the sealing member, and the durability of the sealing member can be improved.

Next, an embodiment of the present invention will be described in detail based on the drawings.
The explanation will be given by assigning the same reference numerals to the same parts.

That is, figure m8 shows a strut j7 used in the suspension of the present invention, where j is a cylindrical member, ko is a shock absorber, Ja is a cylinder of the shock absorber 2, -2C is a piston rond of the shock absorber, and B is the cylindrical member 51. A bracket for connecting to the spindle which is a wheel support member (not shown), a bolt hole for fixing the Hq scissors bracket 3 to the spindle, an 8#i spring catch,

In this embodiment, a plurality of protrusions sJ protruding inward are formed at approximately equal intervals by embossing or the like around the cylindrical member j where the upper end S of the bearing 15 is located, and these protrusions sJ and J of the cylinder 2a m arrangement bearing/jt between the end
It is intended to be supported and fixed. ija is formed on the outer periphery of the bearing/3.

This is an annular recess with which the projection lII is engaged. - 10,000, A plurality of crimped portions 1 are formed at approximately equal intervals on the upper end portion of the cylindrical member 5. This caulking sJ/ is performed by forming two ribs (1) on the upper end periphery of the cylindrical member 5 that are substantially parallel to the cylindrical axis direction of the cylindrical member S. Then, before bending the caulking sut, insert it into the sealing member/A k f11 member 5, lock the lower end of the core material/A c of the holding part/4b with the convex part mK, and then Part/A b upper 111ilII/c washer - machine and swage 1IsJ/l - bend and swage onto the washer. Then, the sealing member tbFi is supported and fixed between the recessed portion U and the convex portion J. Additionally, the receiver member j is welded and fixed to the upper end of the cylindrical member j. Now, the receiver is member d.

Of course, the plate should be formed to have a thickness that is strong enough to withstand the pressure that is applied when it comes into contact with the bumper rubber //.

With the above configuration, bearing lj and 7l member/
! Since it is supported and fixed to the cylindrical member S by the convex part This method can be performed by a simple mechanical operation compared to welding operations such as welding, and the productivity of the strut J is greatly improved.

Further, since no submersion is used to fix the bearing 15 and the rail member/4f, the 7-rail member 74
has no thermal effect. In other words, the sealing member 16 is made of rubber or the like, and if exposed to heat, the sealing member 16 will be thermally hardened and its durability will deteriorate. Therefore, in this embodiment, since no heat is applied to the sealing member/4, durability can be improved.
