The specific embodiment
Below, the 1st form of implementation is described with reference to the accompanying drawings.Fig. 1 illustrates the connecting rod of the automobile-use suspension that obtains according to the present invention, and A is its front elevation, and B is a plane.
This connecting rod 1 has the arm 2 of square tube type and engages incorporate sleeve 3 at its vertical two ends.Among the top and bottom of the formation square tube shape of arm 2 and the application the 1st and the 2nd quite, about the side suitable with the 3rd.About sleeve 3 identical.But can be freely about make differences such as size, material.
Sleeve 3 has the carriage 4 of ring-type and from the part of its peripheral part towards the outstanding installation teat 5 of foreign side's one radially, and 6 dock in the docking section end that teat 5 is installed and the end of arm 2, is engaged and integrated by friction stir.
In the inboard, end of the arm 2 that contacts with this docking section 6, be pressed into from the further outstanding engagement protrusion 7 of teat 5 is installed.Inboard at carriage 4 roughly disposes inner core 9 with one heart by vibration-proof rubber 8.But the structure of sleeve 3 also is arbitrarily, for example also can be inside and outside double-layer barrel type, and the ring portion that is pressed into carriage 4 is installed.
The A of Fig. 2 illustrates and forms carriage 4 carriage blank 14 before.Carriage towards light-alloy or resins such as E direction extruding aluminium alloys, is cut to suitable length with blank 14.
Make carriage become the prominent bar 15 of installation that top view shape (A of Fig. 1) with carriage 4 is integrally formed with annulus identical shapedly and is formed at its part with the extruding cross section of blank 14.Direction of extrusion E is also consistent with the centerline direction of the sleeve installing hole 14a that is formed at carriage usefulness blank 14.
It is continuous towards the direction of extrusion that prominent bar 15 is installed, integrally formed with blank 14 with carriage.In addition, at this prominent bar 15 is installed and is formed transverse process bar 17, this transverse process bar 17 is given prominence at above-below direction towards its projected direction with constituting step.Transverse process bar 17 is as forming with the installation protuberance towards the continuous projecting strip part of the direction of extrusion.
The B of Fig. 2 illustrates such state, and under this state, the transverse process bar 17 of above-mentioned relatively A is formed into slit 18 with the position shown in the chain-dotted line by predetermined space at length direction, and is independent by separating 18 of each slits, thereby forms individualized engagement protrusion 7.The slot width c of slit 18 becomes about 2 times the setting of thickness of slab t (with reference to Fig. 1) of the longitudinal wall part of arm 2.The a of width up and down and the transverse width b of engagement protrusion 7 that is formed at 18 of adjacent slots is consistent with a of width up and down and the transverse width b (with reference to Fig. 1) of the hollow part 2c of arm 2 respectively.
Assembled state when Fig. 3 illustrates interim assembling.The square tube that arm 2 is served as reasons and constituted with the same material of blank 14 with carriage is carried out the given size cutting to the blank of extrusion molding by suitable length in advance and is obtained.The engagement protrusion 7 that cooperates arm 2 at the peristome of an end 2a of arm 2.Engagement protrusion 7 becomes the size that cooperates with the square hole 2c of arm 2.
At this moment, the slot width c of slit 18 becomes roughly 2 times of thickness of slab t of the longitudinal wall part of arm 2, so the longitudinal wall part contact of adjacent arm 2 closely is coupled to slit 18.For this reason, can be towards carriage with the transversely arranged very close to each otherly many arms 2 of the direction of extrusion of blank 14, in the time the bar 15 of dashing forward will be installed be coupled to end 2a, the yielding portion of formation end 2a, so, end 2a can be docked to the installed surface 15a (with reference to Fig. 6) that prominent bar 15 is installed.
In addition, the height of arm 2 all is H (with reference to Fig. 6) respectively with the short transverse width that prominent bar 15 is installed, so when end 2a dock with the installed surface 15a that prominent bar 15 is installed, its that comprises the docking section nearby portion surface can constitute and be in instrument all-moving surface simultaneously.In addition, the other end 2b side of arm 2 is formed at the interim assembling with the engagement protrusion 7 of blank 14 of another carriage by cooperation similarly.
Fig. 4 is for dispose the top view of the interim assembled state of arm 2 transversely arrangedly.If carriage is L with the length of blank 14, the width of arm 2 is W1, and the integral width W2 during then transversely arranged N root arm 2 is W1 * N, and this W2 is consistent with the length L of blank 14 with carriage.
In addition, by the end 2a of each arm 2 is contacted with the installed surface of teat 15, thereby the docking section 6 that makes each arm 2 and teat 15 is as the i.e. continuous arrangement point-blank on closing line 16 of a straight line.Carrying out friction stir along this closing line 16 engages.
Fig. 5 uses the engagement protrusion 7 that is in interim assembled state and the mated condition of end 2a is shown along the cross section of the 5-5 line of Fig. 4.As shown in the drawing adjacent arm 2 is transversely arranged continuous, very close to each otherly like that, and face up and down is in one side.
Fig. 6 is the figure that the state that friction stir engages is shown, and push by the probe 21 to the rotary tool 20 of high speed rotary from docking section 6, thereby friction stir engages the material at opposite sides of docking section 6, and it is integrated.
At this moment, since clamp docking section 6 be in its nearby instrument all-moving surface 22 of moving for rotary tool 20 of the prominent bar 15 of installation and each surface of end 2a of part, be in simultaneously, so, do not have step, can carry out the friction stir joint of high reliability by rotary tool 20.And, because docking section 6 is continuous at all arms 2, so, move along closing line 16 by making rotary tool 20, thereby can make all arms 2 engage integrated by continued operation once with teat 15.
In addition, in the square hole 2c of 2a inboard, end, be pressed into engagement protrusion 7, so, even rotary tool 20 is pressed to end 2a, by by engagement protrusion 7 from inboard supporting end 2a, thereby can stop end 2a towards the recessed such distortion of square hole 2c side.For this reason, can carry out friction stir stable, high reliability by rotary tool 20 engages.And, when dorsal part being carried out friction stir when engaging, by under interim assembled state, making whole upset, engage thereby can similarly carry out friction stir with once series-operation with the table side to dorsal part.
Fig. 7 is used to illustrate that friction stir engages and the top view of cutting action thereafter, after N root arm 2 being joined to a carriage and making it integrated with blank 14, carriage is cut with blank 14 continuing to use the line of cut F shown in the chain-dotted line by each W1 width, then separate forming each connecting rod 1 with the direction of direction of extrusion E orthogonal.At this moment, can make Cutting Length lack, cut easily and promptly, make that can carry out above-mentioned friction stir once engages, thereby can make connecting rod by good production efficiency.
Fig. 8 illustrates the 2nd form of implementation that is made of arm the non-tubular shape member.Owing to only change arm, so, same section is used in the same manner the symbol of above-mentioned form of implementation.State when the A of Fig. 8 illustrates the assembling of arm, carriage shown in the B of Fig. 2 is with the end 2a of the installed surface 15a butt joint arm 2 of the prominent bar 15 of installation of blank 14, transversely arranged this arm 2 that disposes a plurality ofly relatively.
