Specific embodiment
As shown in Figures 3 and 4, according to an illustrative embodiment of the invention for vehicle hanging
The underarm 20 of system has the first separate in front and back bushing mounting portion 21 and the second bushing mounting portion
22.First arm 24 from the first bushing mounting portion 21 extend to the other end at globe joint install
Part 23.Second arm 25 is at the first arm 24 end neighbouring with the first bushing mounting portion 21
Integratedly extend from the first arm 24 at portion's part.Second arm 25 connects to second at the other end
Bushing mounting portion 22.
As shwon in Figures 5 and 6, the second bushing mounting portion 22 includes cylindricality extension main body 22a
And fastener portion 22b integratedly projecting from the axial end portions of main body 22a.Main body 22a
Can be integral by welding etc. with fastener portion 22b.Or, main body 22a and fastener portion
22b can be made up of an original main body.
In response to this main body 22a of the second bushing mounting portion 22, the end portion of the second arm 25
The shaft receiving portion being formed as having cylindrical shape is divided to divide 26.
Shaft receiving portion divides 26 to have cylindrical shape, and it extends a predetermined length in the axial direction, and
It has unlimited ribbon 26a in side in the axial direction.
Therefore, main body 22a of the second bushing mounting portion 22 is inserted tightly into shaft receiving portion and divides in 26,
Supported with the inner surface being divided 26 by shaft receiving portion.
The top end dividing 26 in shaft receiving portion has circular edge line 26b, and along circular edge line
26b is welded so that shaft receiving portion divides 26 outer peripheral edges being integrally attached to main body 22a.
And, in order to increase the sealing wire being formed along circular edge line 26b, in circular edge line 26b
The corner that intersects with unlimited ribbon 26a forms dead line 26c, and along dead line 26c
Welded further.
On the other hand it is contemplated that receive the external force of bending moment form in the second bushing mounting portion 22
When being concentrated with the dead line 26c of stress starting rupturing, by shaft receiving portion divide 26 with open wide
Ribbon 26a and the neighbouring cylindrical surface of dead line 26c form welding hole 26d.Then, axle connects
Receiving portions 26 are soldered to main body 22a also by welding hole 26d.
Therefore, by filling in welding hole and solidifying motlten metal, the stress at dead line 26c
It is dispersed to the welding portion being formed in welding hole 26d so that stress concentration can be reduced.
However, it is possible to any position on the cylindrical surface that shaft receiving portion divides 26 manufactures this welding
Hole 26d, to strengthen attachment force by welding.It is formed at unlimited ribbon in view of welding hole 26d
26a and dead line 26c nearby and manufactures dead line 26c at the two ends of circular edge line 26b,
Preferably on every side of unlimited ribbon 26a, form betwixt symmetrical welding hole 26d,
As shwon in Figures 5 and 6.
Certainly, the invention is not restricted to this situation, but welding hole 26d can also be made only in unlimited
On the either side of ribbon 26a.
Moreover, it is contemplated that to when the second bushing mounting portion 22 bends with respect to the second arm 25, answering
Power concentrates at dead line 26c, so welding hole 26d extends preferably to before dead line 26c,
That is, extend further from circular edge line 26b (rather than dead line 26c) in the axial direction.
Therefore, bending stress is received by welding hole 26d first, and subsequently by dead line 26c and circle
Shape edge line 26b receives so that can prevent in the second arm 25 and the second bushing mounting portion 22
Between adjacency section office deform.
As shown in Figures 3 and 4, according to an illustrative embodiment of the invention for vehicle hanging
The underarm 20 of system has the first arm 24 and the second arm 25, and the first arm and the second arm pass through
Compression molding forms single metal plate (for example, steel plate).
In particular, as shown in Figure 7, the second arm 25 preferably have fromShape (ginseng
According to C-C section) continuously become round (with reference to A-A by oval (with reference to section B-B)
Section) section.
According to this section of the second arm 25, from the circular cross-section of end sections 25a, permissible
Realize improving support force on the second bushing mounting portion 22.
And, compared with traditional the second arm (see figures.1.and.2 15), by from first
Extend in arm 24Tee section and in central area BShape becomes
The continuous section of end portion office circular cross-section, it is possible to achieve improve the intensity of the second arm 25.
First arm 24 has over the whole lengthThe section of shape.
Although disclosing the illustrative embodiments of the present invention, without departing substantially from the scope of the present invention and essence
In the case of god, can have various modifications, interpolation and replacement.Therefore, above-mentioned embodiment must
Must be considered for describing the present invention not for restriction an example of the present invention.
