As shown in Figure 1, Figure 2 and shown in Fig. 3,4, resilient bushing 6 possesses: central shaft 7, and it has the axle center P reported to the leadship after accomplishing a task with vehicle direct of travel Y; Roughly cylindric outer member 11, it is arranged on around the radial outside of central shaft 7; And resilient member 10, its intervention is arranged between central shaft 7 and outer member 11.
Central shaft 7 has: possess the mounting hole 7h and assembly department 7B, the 7B at the two ends, left and right of section oval in shape that to insert etc. for bolt; The major diameter face 16 of the smaller diameter face 15 in left and right, central authorities; Inclination outer circumferential face 13 between each smaller diameter face and major diameter face, central shaft 7 forms the axle with the symmetrical shape of central part 7A, and described central part 7A forms its diameter and more more becomes large shape towards central part from the left and right sides.
With regard to outer member 11, it is made up of the sheet metal of steel for mechanical structure pipe etc., the shape of the also cylindrical shape that left and right is tapering is shortened in two ends, left and right, and be made up of the cylinder of the oblique cylinder portion 11B with large diameter vertical tube part 11A and top tapered, wherein, large diameter vertical tube part 11A is positioned at the left and right central authorities of certain diameter; The oblique cylinder portion 11B of top tapered is respectively formed at left and right with its diameter from the state that vertical tube part 11A more more diminishes away from P direction, axle center.
As shown in Figure 1, the width dimensions of this outer member 11 sets in almost equal with the width dimensions that the major diameter face 16 of central authorities and the inclination outer circumferential face 13,13 of left and right are added mode.
Resilient member 10 is following complex structure bodies: have the width roughly equal with the width dimensions of outer member 11, the gap part 10B of outer portion 10A, 10A and left and right central authorities and the pairing left and right possessing ring-type tilts, and possess metal breast wheel (ring bodies an example) 17 integratedly at the outer circumferential side of each inclination outer portion 10A, and the complex structure body of the shape of its section roughly in H-shaped (shape as pulley or Climbing top Yo-Yo).Each breast wheel 17 becomes integrated by hot sticky or bonding by Vulcanization as a rule with resilient member 10.
From the antirust aspect of mould-forming aspect or central shaft 7, be preferably formed at gap part 10B and cover central part 7A and for the ring-type membranous part 10b of the thin wall shape rubber that connects pair of angled outer portion 10A, 10A, but this ring-type membranous part 10b can not yet.
Namely, use as resilient member 10 and there is the component of following shape: the breast wheel 17 carrying out the hard material of the corresponding part 11t of undergauge processing for block is assemblied in the outer circumferential side of outer portion 10A, and by the shape that caves in the mode that is circumferential groove shape relative to axle center P in the position being positioned at the radially inner side of vertical tube part 11A.
Breast wheel 17 possesses: the large outer circumferential face 17a with certain diameter, and it is embedded in the straight tube inner peripheral surface 11a of vertical tube part 11A; Tapered outer circumferential surfaces 17b, it is embedded in the inclination inner peripheral surface 12 of oblique cylinder portion 11B; Hook-shaped circumferential part 17c, it is for the terminal part of block oblique cylinder portion 11B; Tapered inner circumferential surface 17d, it has, and the tilt angle equal mutually with tapered outer circumferential surfaces 17b is also outer is embedded in outer portion 10A; And little inner peripheral surface 17e, its then in one end of the path side of tapered inner circumferential surface 17d be embedded in outside the state of certain diameter tilt outer portion 10A, described breast wheel 17 as a whole in relative to axle center P tilt section shape.
In addition, under the state of the resilient sleeve 6 shown in Fig. 1, each outer portion 10A that tilts between tapered inner circumferential surface 17d and inclination outer circumferential face 13, is in P direction, axle center and the state compressed relative to this both direction of radial direction of axle center P, namely form be pre-compressed by press part 14.
This precompression is, when carrying out the assembling of resilient bushing 6 (during assembling), formed at breast wheel 17 and to be formed in the technique of oblique cylinder portion 11B, formed by compressing between inclination inner peripheral surface 12 and described inclination outer circumferential face 13 by each inclination outer portion 10A by press part 14, for this precompression, will be described in detail hereinafter.
Inclination inner peripheral surface 12, inclination outer circumferential face 13 and tapered outer circumferential surfaces 17b, have the structure tilted with identical mutually and homogeneous angular relative to P direction, axle center, but do not have this structure and also can.
(embodiment 1)
Then, the manufacture method (making method) of resilient bushing 6 is described.The resilient bushing 6 with said structure is the symmetrical shape with center line C, and has clear and definite feature when assembling outer member 11.
Namely, make resilient member 10 and outer member 11 to axis direction relative movement, and after the outer embedding technology a (with reference to Fig. 2 (a)) of outer member 11 fitted in the resilient member 10 be under the outer state being contained in central shaft 7, carry out compression process b, thus make resilient bushing 6, wherein, compression process b is, by in outer member 11, the corresponding part 11t that is contained in outer portion 10A outward carries out undergauge processing, between corresponding part 11t and inclination outer circumferential face 13, compression is tilted the technique (with reference to Fig. 2 (b)) of outer portion 10A thus.
In addition, in order to easily successfully carry out outer embedding technology a, the diameter of outer member 11 is set to diameter large a little, and will carry out also can before compression process b after overall diameter reducing process outside embedding technology a, wherein, described overall diameter reducing process, carries out undergauge in the lucky closely outer mode being embedded in large outer circumferential face 17a of outer member 11 to the entirety of outer member 11.
Specifically, first, as shown in Fig. 2 (a), by being embedded in each inclination outer circumferential face 13 outside the outer portion 10A that each tilted and being embedded in major diameter face 16 by outside ring-type membranous part 10b, and each is tilted be embedded in breast wheel 17 outside outer portion 10A state under carry out the methods such as hot sticky or bonding by Vulcanization, prepare in advance thus form integration breast wheel 17, resilient member 10 and central shaft 7.
For the external diameter of the resilient member 10 be not also pre-compressed, namely for the diameter of large outer circumferential face 17a of breast wheel 17 and the internal diameter of outer member 11, from the viewpoint of the preferably equal value of successfully carrying out outer embedding technology a, but it also can be unequal value.
In this case, each outer portion 10A that tilts of left and right is not also compressed, therefore, whole width D as resilient member 10 is the width between two breast wheels 17 in left and right, and the whole width D between this breast wheel 17,17 is significantly than the whole width d long (D > d) of the outer member 11 under the certain diameter state shortened before processing.
Then, if outer embedding technology a terminates, then the compression process b as shown in Fig. 2 (b) is carried out.In this compression process b, by machining cells such as rotary desk type press machinees, undergauge processing (compressing processing) is carried out at the left and right two end part of mode to outer member 11 more more diminished towards the one end in P direction, axle center with diameter.Come to be formed in left and right to tilt in the technique of outer portion 10A by the processing of this undergauge, the end of outer member 11, i.e. corresponding part 11t process forcibly fitted in tapered outer circumferential surfaces 17b by undergauge, and each outer portion 10A that tilts moves towards direction close to each other in P direction, axle center forcibly via breast wheel 17 thus.
Now, the outer portion 10A of the inclination of clamping with inclination inner peripheral surface 12 and inclination outer circumferential face 13, towards direction and the P direction, axle center at the center, left and right of resilient member 10, namely, 10A, 10A are compressed towards direction close to each other and relative to this both direction of direction of axle center P undergauge in each outer portion, thus formed be pre-compressed by press part 14.Its result, has inclination outer circumferential face 13 and each inclination inner peripheral surface 12 about being separately positioned on by the resilient member 10 of press part 14.
Namely, in compression process b, the mode of the inclination inner peripheral surface 12 more more diminished towards the one end in P direction, axle center with the internal diameter forming corresponding part 11t carries out undergauge processing, and compresses towards relative to the direction of axle center P undergauge and this both direction of P direction, axle center the outer portion 10A that tilts.
In the present embodiment, the metal breast wheel 17 of strong compressive force adjoint for the undergauge machining being used for bearing corresponding part 11t is arranged on resilient member 10, such as, when almost only bear necking square to or the machining stress in P direction, axle center, also only can form resilient member 10 by rubber.In addition, with regard to resilient member 10, the amount of recess of the less or radial direction of the left and right width of its gap part 10B less also can, or do not have gap part 10B can yet.
As shown in Figure 5, the embedding hole 4H of cap 4 can be formed following shape: increase the internal diameter of the central part of left and right directions (P direction, axle center) width and form diameter along with the inclination inner peripheral surface 18 diminished gradually towards two ends, and its section coordinates the concave shape of outer member 11 shape.If this shape, under the state of being assembled by bolt 9, the inclination inner peripheral surface 18 of left and right plays function as the anticreep wall for preventing resilient bushing 6 from coming off to P direction, axle center, is preferred viewed from this respect.
(other embodiments)
As other examples of resilient bushing 6, as shown in Figure 6, it also can be assemblied in the end of draw-bar (link) 20.
Draw-bar 20 bears component as single torque and forms, and its erection is attached at one that is supported in as in the traction framework 22 of the vehicle frame 21 of rail truck and a pair main backstop 24,24 of bogie frame 23.
With regard to traction framework 22, it is to have the flange 22A that is bolted to vehicle frame 21 and under vertically disposed state, is formed as possessing the metal components of two fork underpart 22a, the 22a crossing over draw-bar 20.One in each central shaft 7,7 of draw-bar 20 is bolted to two fork underpart 22a, and another is then bolted to from projecting two forked strut (stay) 24a of main backstop 24.
Draw-bar 20 comprises: the driving component 20A formed by tube material; And respectively at metal cylinder wheel hub 20B, 20B of two ends deposition integralization of driving component 20A, and resilient bushing 6 be embedded in each wheel hub 20B, 20B in outer member 11 state under assemble.In this case, what each cylinder wheel hub 20B can adopt cap 4 as shown in Figure 4 splits bolt fastening structure, also can adopt the structure of inner peripheral surface that be only pressed into by vertical tube part 11A, that have certain diameter, but for simplicity omit detailed diagram.In addition, the inner peripheral surface of this certain diameter also goes for: for the cap 4 of the resilient bushing 6 (with reference to Fig. 5 etc.) of embedded embodiment 1.
Next, to adopting the resilient bushing 6 of said structure and being described based on the action effect etc. of its manufacture method.
With regard to resilient bushing 6, the part fitted in resilient member 10 in outer member 11 has inclination inner peripheral surface 12, and the mode that this inclination inner peripheral surface 12 more more diminishes towards the one end on the width direction of the axle center P along outer member 11 with its diameter relative to axle center P tilts; The part being embedded in resilient member 10 in central shaft 7 has inclination outer circumferential face 13, this inclination outer circumferential face 13 tilts with the direction identical mutually with inclination inner peripheral surface 12 relative to axle center P, and resilient member 10 have between inclination inner peripheral surface 12 and inclination outer circumferential face 13 compress (precompression) by press part 14.
The feature of the present embodiment is, make resilient member 10 and outer member 11 to axle center P direction relative movement, and after the outer embedding technology a of outer member 11 fitted in the resilient member 10 be under the outer state being contained in central shaft 7, carry out compression process b, wherein, compression process b is, by in outer member 11, the corresponding part 11t that is contained in outer portion 10A outward carries out undergauge processing, between corresponding part 11t and inclination outer circumferential face 13, compress (precompression) thus to tilt the technique of outer portion 10A.
Therefore, suitably can set the conditions such as the angle of inclination of inclination inner peripheral surface 12 or inclination outer circumferential face 13 or its decrement, at random can adjust setting thus by the rigidity ratio of the rigidity (or spring constant) of the rigidity (or spring constant) in the P direction, axle center of the central shaft 7 in press part 14 and radial direction.Thus, at random or can as far as possible at random set the rigidity in P direction, axle center of central shaft 7 and ratio, i.e. the rigidity ratio of the rigidity of radial direction, and the moving vehicle resilient bushing 6 and manufacture method thereof that can possess required rigidity ratio can be provided.
What make the outer portion 10A of inclination as the unfinished state of parts be formed as finishing stage (assembling condition) by the precompression of press part 14 processing is, integration is formed in order to make the outer member 11 in compression process b and breast wheel 17, be combined the method for the shortening processing of corresponding part 11t, therefore, it is possible to produce very expeditiously.And realized at one stroke to P direction, axle center and this both direction radial from the viewpoint of this precompression by shortening processing, producibility is excellent.
Be equal mutually relative to the tilt angle (cone angle) of axle center P respectively as to clamp by the breast wheel 17 at the position of press part 14 and inclination outer circumferential face 13, therefore, uniform precompression can be implemented to each outer portion 10A that tilts.This precompression realizes by means of only the movement in the P direction, axle center of the adjoint breast wheel 17 of the undergauge of corresponding part (end) 11t, therefore, following advantage is also had from the viewpoint of this: realize by the homogenization of the compressive stress of press part 14 and then the stable performance realizing resilient bushing 6.
And make the oblique cylinder portion 11B of outer member (foreign steamer) 11 and breast wheel 17 be fitted together to conical by its shape, therefore, these outer member 11 and resilient member 10 can not P directions, disalignment.In addition, outer member 11 and embedding hole 4H are also fitted together to conical by its shape, can stable support resilient bushing 6 and can not to produce dislocation mobile for cap 4.
