The specific embodiment

In order to understand invention better, need to understand applied unsteady sidepiece supporting member.

To in the situation of two main modification, be described below this.

For this reason, will describe the primary member that constitutes this sidepiece supporting member that floats below respectively, it was being described in first to file.

The present invention is applied in two from left to right continuous as shown in Figure 2

carriage body construction

1,2, and its relative two

ends

3,4 are hinged on the same bogie truck 5, and the latter has two

axletrees

6,7 and a underframe 8.Underframe 8 is supporting the end face bearing 9 of a hemisphere 10, and it is made of two pivotally attached complementary elements, and one of them is that sphere is held body 11, and another is to be embedded in this to hold hemisphere 12 (Fig. 9) in the body.

End face bearing 9 is connected in a central articulation piece 13 public, that sway and have the side on oscillation idle running, and it has constituted main articulation piece, makes

end

3,4 interconnect pivotally thus.

End face bearing 9 and public central articulation piece 13 have constituted the compound articulation piece with three degree of freedom, and it allows to take place all and the relevant inclination of motion of travelling, comprising lateral oscillation and oscillation in the pitch mode.

The

opposite end

3 and 4 of carriage body construction interconnects by the

sidepiece attaching parts

14 and 15 of a discontinuous once in a while bonded assembly special use respectively in every side between the two.

Support its end when moving, be provided with the

sidepiece supporting member

16 and 17 of two activities, all supporting one end member in discontinuous bonded assembly

sidepiece attaching parts

14 and 15 on each sidepiece supporting member respectively in order to be at continuous

carriage body construction

1,2.

According to following apparatus of the present invention, these discontinuous bonded assembly

sidepiece attaching partss

14 and 15 constitute in common mode.A vertical movable base 18 is installed on the spacing suspension gear, and it has constituted the bogie truck suspension assembly 19 of the other support of the so-called bogie truck of technical term.End face or its lining wipe contact of pressured back plate 20 and base 18, it has a hinged support spare 21, and it is holding a for example articulation piece 22 of jointed shaft 23 types.

Carriage body construction

1 and 2

end

3 and 4 have the extension of some end claw types at each discontinuous

sidepiece attaching parts

14 and 15 places, at each discontinuous sidepiece attaching parts place, realized that the other support of an end and bogie truck is connected, the other end then is in the state of lifting according to the end of respective end pawl or the supporting state of contact realizes being interrupted once in a while or closed connection.These end pawls that are present in every side are two kinds of forms: be used for a yoke end pawl 24 of end 3, and the two pawls 25 in an end that are used for end 4, they are toward each other in public central articulation piece 13.

The two pawls 25 in end are by two

bluff pieces

26, and 26a constitutes, and one of them, has the lower surface of being arranged to respect to pressured back plate 20 almost parallels by preferably two.

Especially special, each sidepiece hinged support spare according to the present invention has following element.

The base 18 of plate-like is vertically installed slidably by the core 27 of its for example cylindrical protrusion, so that it can be directed to slidably in for example columniform seat 28, this cylindrical seat 28 is arranged on the fixed support 29 that is connected in bogie truck underframe 8.By the central block 30 of a bearing fit in center cavity 31, can make guiding function become better.

Base 18 is placed on the bogie truck suspension assembly that is made of at least two

compression springs

32 and 33, and the end that is pressed against spring by end member is to form this suspension assembly 19.The spring 32 of suspension assembly and 33 is by some

inner members

34 and 35 channeling conducts, and in the compression-stretching routine when working corresponding to suspension assembly, spring moves along these inner members.

Fig. 6 and these

inner members

34 and 35 shown in Figure 8 play a part guiding and spacing simultaneously.Hereinafter they are called guiding and limit element.In fact, the lower surface of base 18 will be done spacing the contact with the front of limit element with these guiding when its stroke finishes, thereby can weaken these motions at some during corresponding to the significantly motion of base 18 idle runnings.

Can find then, be installed in the element 36 that base 18 lip-deep pressured back plates 20 are equipped with a friction and supporting with the friction support pattern.Pressured back plate 20 can be realized by various technical scheme, for example by a plurality of stacked plates, such as the three ply board shown in the figure, and forms a kind of composite structure, but also can be any other structure.

Pressured back plate 20 has a friction supporting region 37 on the surface thereon, for example is centered around extending of hinged support spare 21 on every side and mutually.This friction supporting region 37 is configured to around hinged support spare 21, but with it at a distance of some distances, and the single-piece of a shaped as frame or the friction insert 38 of multi-piece type be equipped with; Being separately positioned on two bluff pieces 26 of the two pawls 25 in end and corresponding each

base

39 and 40 on the 26a lower surface just is bearing on this friction insert 38.

The edge that the friction insert 38 of shaped as frame for example is configured to make its inner circumference and hinged support spare 21 is at a distance of some distances, and for the upper surface of pressured back plate 20, it is recessed down slightly towards the bottom.It is embedded in the friction supporting region 37, and make a solid slab or a tectal form by the material of great friction coefficient, thereby in the end bluff piece 26 of two pawls 25, when the friction insert 38 of the base 39 on each lower surface of 26a or 40 in friction carrying 37 done Frictional Slipping and supporting work, the most energy of can decaying.

Can be provided with two inserts 38, they are in each other near on vertical position of hinged support spare 21.

According to shown in first modification, this hinged support spare 21 is configured to vertical stirrup shape, is rendered as the form of mechanical lock, for example is made of two side parts and assembles by the pin 41 in the pressured back plate 20.Hinged support spare 21 has the groove 42 that a pivot 23 for articulation piece 22 moves at an upper portion thereof.This groove 42 is formed into the horizontal cylindrical cavity in the bottom, by two openings or extend towards the top by the branch that horizontal safe attaching parts merges reinforcement by connection.The pivot 23 of articulation piece 22 can along this groove 42 from the top position downwards the position move, and move in reverse direction.The distolateral portion of fork catch 24 is installed on this pivot 23.For moving of the pivot 23 of articulation piece 22, groove 42 has towards the cross-sectional plane of the substantially elliptical of top opening, but opening part preferably seals by horizontal safe attaching parts, for example by (unshowned) bolt.

The pivot 23 of articulation piece 22 along it shifting chute 42 thereunder the vertical mobility between position and the top position show as vertical idle running as freedom of motion, its in conjunction with pressured back plate 20 do not fixedly mount and range of movement is between two pawls 25 in end and pressured back plate 20.As in the following operation explanation will as described in, above-mentioned range of movement correspondence the idle running between the position lifted of the two pawls 25 of bearing position and end.Also can adopt opposite mobility, promptly hinged support spare 21 is with respect to the mobility of pivot 23, and in this case, pivot 22 is fixed.Certainly, the various situations in conjunction with these two kinds of mobilities also all are feasible.

According to a modification, hinged support spare 21 can be made for respect to pressured back plate 20 can move, with fully independently motion mutually between the end that obtains carriage body construction.According to this modification, hinged support spare 21 passes pressured back plate 20, so that its thrust is directly affacted on the friction member 36 of the suspension assembly 19 that constitutes the other support of bogie truck.For this reason, this hinged support spare 21 is contained in one (unshowned) slidably and passes in the opening at pressured back plate 20 centers.Motion by some grooves or other member channeling conduct makes the accurate supporting of working well with supporting member 21 bottoms become possibility.Certainly, in this case, pivot 22 no longer is fully essential along the idle running of its groove, and this is because guaranteed this idle running by its moving of supporting member 21.

It is also conceivable that another modification, according to this modification, hinged support spare 21 also moves with respect to pressured back plate 20, but acts on indirectly in the other support of the bogie truck that passes this plate 20.In this case, can between hinged support spare 21 and plate 20, provide one to replenish idle running by the spacing before contacting.

In motion, according to by a carriage body construction, or the motion that causes of this same carriage body construction one side or opposite side, float the sidepiece supporting member just can along one or other direction move, for example move towards the top from the bottom, perhaps opposite.

The state of end is shown in Fig. 5 to Fig. 8.

Thrust come from the left side carriage body construction 1 situation under (Fig. 5 and Fig. 6), when when wave the bottom, the fork catch 24 of end will be pressed in suspension assembly 19 or the other support of bogie truck by hinged support spare 21, obtain balance or the spacing in-to-in guiding locating

part

34 and 35 that is contacted with up to the

compression spring

32 and 33 by suspension assembly 19.In fact, in case pivot 22 abuts to the bottom of groove 42, suspension assembly just under the thrust of the respective end 3 of carriage body construction 1, makes this suspension assembly sink in the motion of decay because of the effect of suspension assembly spring.

If thrust also has horizontal component, pressured back plate 20 just carries out Frictional Slipping on friction support insert 36.

Can in its groove, rotate during for pitching, be provided with pivot 22.

In contrast, in the situation of Fig. 7 and Fig. 8, the two pawls 25 of supporting can be subjected to the thrust to the bottom, and just two elements 26 of the two pawls 25 of supporting and 26a are pressed on the friction supporting region 37 by its

lining base

39,40 and make suspension assembly 19 sink.Suspension assembly 19 descends together with hinged support spare 21, owing to have along the freedom of motion of elliptic cross-section groove, just pivot 22 has been stayed its position in groove 42.

Because do not have functional mechanical connection between the

bluff piece

24,25, any combination of above-mentioned motion all is possible.

So just make the motion of end of a carriage body construction in used maximum idle running scope, be independent of the motion of another carriage body construction end subsequently.

In the modification of hinged support spare 21 with respect to pressured back plate 20 independent slips, it is fully independently, and each end of each carriage body construction can both be moved alone and act on the friction member 36 of the other support of bogie truck.

The total advantage of said apparatus is that it has at least two idle runnings, and one at hinged support spare 21 places, and another is present between end pawl 25 and the pressured back plate 20 when travelling motion.

According to the characteristics of end motion, these idle runnings must not possess simultaneously.These idle runnings provide the idle travel of avoiding passing motion to another end under the situation various commonly used of carriage body construction in motion, and moreover, also the spring by suspension assembly 19 has alleviated these motions.

Second modification that the present invention adopts is shown in Figure 10 to Figure 19.It comprises identical general function and equivalent unit.Identical or essentially identical element is marked with identical figure notation.

In this second modification, can see its horizontal pivot of 23 of being labeled as, so that farthest reduce rocking couple to bogie truck other support the reduction as much as possible articulation piece 22.In fact, the effect of friction is to produce a couple, and friction member is away from pivot, and it will be firmly pressured.For excellent function,, need make this effect minimum in order to reduce to wear and tear and stability when avoiding couple to have influence on the compartment travelling.

So just seen a base 18 that is installed in the vertical activity on the spacing suspension gear again, they have constituted the bogie truck suspension assembly 19 of the other support of the so-called bogie truck of technical term.Have a hinged support spare 43 with the end face of base 18 or the pressured back plate 20 of its lining wipe contact, it is holding one can be around the special articulation piece 44 of horizontal shaft rotation and vertical shifting.Although multi-aspect articulation piece for example the ball-and-socket type joint type or equivalents also is suitable for the idle running of the motion of doing, has only vertical shifting and related to round the rotation of the horizontal shaft that passes articulation piece.

One of them end pawl 45 has corresponding to two branches 46 of two pawl 25 similar same form and 47, but difference is that its other end pawl is mounted in the central authorities' end pawl 48 on the articulation piece 44 at its place, end.

More specifically referring to Figure 11 and Figure 12, central authorities' end pawl 48 ends at one towards the end of bottom and have a cavity volume, and cavity volume shape is configured for the holding tank 49 of articulation piece 44.Articulation piece 44 is bearing on the hinged support spare 43 of parallelepiped piece 50 shapes for example.The for example receiver element 51 of straight line shown in Figure 12 also is housed on this hinged support piece, and it matches with the contact 52 that is configured in groove 49 bottoms, to be configured for the security component of hinge function.The hinged support spare 43 of these anchor plate 50 shapes has the attached supporting member 53 of convex outer surfaces on its side, this attached supporting member 53 when work with respect to attached to the liner 54 on groove 49 sides.This liner 54 has a flat outside face, the contact surface when this has reduced to contact with the outside face of support sleeve 53.

Here should be appreciated that hinged support spare 43 is anchor plates 50 that are positioned on the pressured back plate 20.

As previously mentioned, this is installed on the back plate 20 or the hinged support spare that is fixed with one with it, can be linked to each other with plate 20 or is interrelated with it by different modes.Especially this hinged support spare can be installed versatilely with respect to plate 20.

Be used to constitute by shown in the articulation piece 44 of hinged support spare 43 supportings and used mechanical component be to produce small idle running amplitude during according to work to be selected.

Can reach a conclusion by the research to above-mentioned member: will hold the motion of pawl to separate this total function and carry out according to mode of the present invention fully, this is a modification in the scope of the invention fully.

As for operation scheme, its main phase can be referring to the above-mentioned detailed description that first modification is carried out.Particularity during this second modification operation is that the articulation piece 22 that will have the axle 23 of vertical shifting replaces with special articulation piece 44.The function of this special articulation piece 44 can satisfy the function declaration of this assembly.

When one section of generation or the generation motion of the feasible end of another section bending pawl place, end pair pawls 45 lean on by the sliding pressure with the first modification same way as and work.In contrast, central authorities' end pawl 48 directly will encourage the Motion Transmission of articulation piece 44 to give articulation piece 44.This can absorb all kinds of deviations and motion, it may be vertical or round the inclination of horizontal pivot, and above-mentioned phenomenon is alleviated, and realize separation as all pawl motions of main purpose of the present invention.

The improved total creative thinking of the present invention is to have designed a kind of anti-shake device, rocks device for limiting in particular for of pressured back plate 20, makes the floating support device be contacted with the other support of this bogie truck by this pressured back plate.

This device separately or use in pairs is other scheme of pressured an of shaped as frame or a guide rail or two ends or various enforceable usual means, maybe can reaches the combination of this assembly effect same.

A kind of device based on two moment of torsion sheets as indefiniteness embodiment will be described below, one end of each moment of torsion sheet is fixed in an end of pressured back plate 20, and the other end of each moment of torsion sheet is fixed in the side plate as the part of the vehicle frame of railway bogie or its end face bearing.

Improvement preferred embodiment of the present invention relates to a kind of device that limits jigging motion, and this jigging motion is mainly caused by pivotal axis 23 by the supporting member of the end pawl of Y-piece 24, and/or is caused by the supporting member of the two pawls 25 in end.

Because the similar characteristics of this supporting member, this device comprises two similar reinforcing members, and they are fixed in the longitudinal end that presses back plate 20 of the supporting structure effect on the lining that plays the other support of bogie truck.

According to shown in modification, relate to two and independently

reverse sheetmetal

55 and 56, an end of pressing back plate 20 is fixed in their

end

57 and 58, and be respectively that another end of 59 and 60 is installed on for example is on the supporting member that is independent of the other support of bogie truck of an adjacent side plates 61, it for example is fixed on vehicle frame, together move or not together motion with vehicle frame, or its motion relatively.Shown in the modification, be chosen as a supporting member that is fixed on this end face bearing.

It is very important having fixed thereon that this supporting member that reverses the sheetmetal end can not excited by the motion of the articulation piece institute combination of being supported by floating support spare.

These reverse the connection arranged side by side between two ends of pressing back plate 20 that sheetmetal 55 and 56 constituted same floating support spare.Their simultaneously and constitute a separate connection at every turn, to resist the moment of torsion of the contiguous fixed point on this public side plate 61.

These moment of torsion sheets of reinforcing side by side provide a mechanical, to reduce even to offset the power of being transmitted by the rotation articulation piece that presses back plate 20 supportings of rocking fully.

This connection has guaranteed that also one replenishes drag and is used for a good hardness of this resilient suspension, this thereby avoided causing sideway movement unstable and distortion.

It has also guaranteed this supplementary function of convergent mode of motion, and it can strengthen the degradation of energy that is undertaken by friction.

According to a modification, same torque blade can be used to connect two ends of pressing back plate 20 of same floating support spare.Thereby this public torque blade has an end that is formed into fork-shaped.

According to another modification, same torque blade can be used for two ends of pressing back plate 20 accordingly of cooresponding two floating support spares.For this reason, each two ends that connect corresponding floating support spare of an independent torque blade, the middle part of this torque blade are fixed in for example on the supporting member of side plate 61.

Can use a public torque blade, and its two ends are formed into fork-shaped to constitute the anti-shake device of two floating support spares.

The performance of floating support device that has anti-shake device of the present invention is as follows.

When the motion of related end mainly order about cause one vertical and/or horizontal when rocking trend, almost all neutralizations of opposing torque that the continuous pressure on a certain end of this pressured back plate 20 is caused by one or more torque blade immediately.

Opposing torque is relevant with the power of rocking, and when the power of rocking was reduced to zero gradually, opposing torque also reduced gradually up to zero, thereby can make it that good Frictional Slipping is arranged.

Torque blade also has and is primarily aimed at drag longitudinally, has strengthened the decay of motion and thereby has also improved decay to energy.

The present invention improves and also is applied to shown in Figure 10 to 19 and aforesaid device.

One or more anti-shake devices are formed into preferably two individual branches 62 that have as shown in figure 10 at every turn, two metal torque blade of 63, but the end of pointing to public central articulation piece 13 then is fixed on the same supporting member 64 that for example is fixed on the end face bearing.These torque blade constitute an anti-shake assembly of every side, and its profile is two bevelled U-shapeds and links together by a public branch 65, and the end of two

other branch

66 and 67 is fixed in the every side that presses back plate 20 accordingly.

Certainly, other embodiment in same concept of the present invention all is possible, especially the equivalent device of torque blade.
