Large-area brake lining, for example employed usually in the rail vehicle disk type braker, in the braking process of energy abundance, also just not about constant surface pressure on its rubbing surface.This is from the uneven power transmission of the side of hold down gag in addition when for example using the swallow-tail form guiding device, also owing to the following fact, promptly owing to thermal expansion from its surperficial friction material, therefore make the surface of liner and brake disc hotter zone unexpectedly occur, wherein these area load are higher and become hotter than adjacent area in the process of further braking continuously.The consequence that this " focus " on brake disc and liner causes is to produce hot tearing in advance and because thermal overload damages liner on brake disc.Especially (resin bonded material, metal sintering material) forms said process especially consumingly in hard liner material.
Organically the friction facing of chemical combination is made up of with fixed block the friction material of reality itself basically, for example forms with the steel plate form that has the liner that is stained with or by the liner that has metal reinforced swallow-tail form profile.
A whole set of, cause having produced the sintering brake lining in particular for the research and development of the brake lining of the rail vehicle that runs at high speed, they directly or by means of orifice plate are fixed on the support plate.Support plate has integrated swallow-tail form profile.After the wearing and tearing of such friction member with the liner of the whole series, comprise that support plate is all removed and by new replacing.The sintering brake lining is also special since these are former thus than organic liner costliness many; Related here is your 4-6 factor.
In further improving in (DE 44 36 457 A1), not only in order on the rubbing surface of brake disc, to make surface pressure evenly but also owing to the reason that reduces cost, developed removable friction member, these friction members import in the support plate spheric thrust bearing of (being called supporting slice here) swingably by means of the spherical segment of design on its back side.Fixedly axle journal extends through this support plate from spherical segment, and partly by another supporting member opening of (being called the liner bearing here), can arrange that this supporting member is used to make the impacting force on the liner support even.Therefore friction member or its fixedly structure height of axle journal are not limited to the structure height of the use arranged of support plate; These modes with needs groove necessary for the axle journal end, in the liner bearing has demonstrated the structural consumption that need be avoided.
The fixing of friction member in such structure realize by means of cup spring, promotes this spring by the fixing end of axle journal in order to assemble friction member.In the gap of cup spring between support plate and liner bearing, that is to say that the distance between support plate and liner bearing must equal the thickness size of cup spring at least.This measure also helps the structural extension that will avoid on the axial direction of friction member.
The model utility content
Set out thus, the purpose of this utility model is to realize a kind of brake lining with removable friction member, the disk type braker that is used for vehicle, especially rail vehicle, wherein, the structure height of supporting structure further reduces with respect to the said structure of known type.Should realize, under situation about keeping, structure height is limited to the spendable size of support plate (supporting member that just has spheric thrust bearing) to the easy assembling possibility of the draught spring (Spannfeder) of fixing friction member and dismounting possibility.
Used brake lining for fear of above-mentioned shortcoming (at first when using agglomerated material) in addition, it has by flexibly mounted discrete component (DE-OS 43 01 006).Yet main the discovery has two shortcomings in such structure: the surface pressure on independent element is not constant all the time, and it depends on separately the surperficial constant of spring deflection corresponding to the elastic insert of independent element.Liner expense total cost is very high and therefore very expensive in addition; Price has improved 4-6 doubly with respect to the liner of an integral body of organic chemical combination.
Second purpose of the present utility model is to utilize in this wise a kind of brake lining that belongs to this type of of simple device design on the structure, can realize the surface pressure homogenization on the rubbing surface of brake disc.Should make the tight power of stagnation pressure on independent liner element, realize the distribution that clearly limits.For save cost also possible be to change brake lining or identical part in the favourable mode of cost.
In order to realize first purpose of the present utility model and second purpose, a kind of brake lining with removable friction member has been proposed, the disk type braker that is used for vehicle, especially rail vehicle, this brake lining has the support plate of bearing friction spare, support plate can utilize friction member to be pressed on the rubbing surface of brake disc by effect braking maneuver in the above, and this brake lining has following characteristics: a) friction member is arranged in the spheric thrust bearing of support plate swingably by means of the spherical segment of design on its back side; B) spheric thrust bearing is passed through by perforation to axial centre respectively, and perforation changes the perforation in the support plate over to; C) fixedly axle journal extends from spherical segment; D) fixedly axle journal has supported the draught spring of straining friction member on the direction of spheric thrust bearing respectively.
According to the utility model, a kind of brake lining has also been proposed, be used for the especially partially lined-disk type braker of rail vehicle, comprise a plurality of liner elements, the liner element has on the fixed block of supporting mass guiding and can be pressed on the rubbing surface of brake disc by the braking maneuver that acts on the supporting mass, wherein the liner planning is on supporting slice, and support plate is fixed on the supporting mass swingably, and this brake lining has following characteristics: a) the liner element leads on the side of facing of support plate swingably by means of spherical linkage respectively; B) the liner element is tightened up with respect to supporting slice by means of spring ground respectively in the category of its swing property.
According to the utility model, be provided with a kind of instrument in order to assemble such friction member, when application is provided with the friction member of fixing axle journal and draught spring, be used for friction member is assembled to the support plate of disk type braker, this instrument has following characteristics:
A) instrument comprises the spring device for spreading of the tappet shape with pillar, and design has cone on the underpart of pillar;
B) pillar leads within the tappet of sleeve shape and strains by the draught spring that is positioned at tappet inside; With
C) tappet is furnished with the tappet head in this wise, promptly by overcome draught spring power realized, tappet moves with respect to pillar, the draught spring that utilizes its supporting leg to strut on cone can be by means of with respect to the cone underpart of tappet movably, on the fixedly axle journal of shifting friction member under the situation of slipping onto, and can be after unclamping cone automatically in the groove of fixing axle journal, lock.
Although the pairing that is made of friction member and support plate is being under the minimum situation of structure type, but when using the draught spring that to assemble fast and to dismantle, in the shortest time, realize the replacing of friction member, and needn't make real support plate from other supporting structure, for example break away from from the liner bearing.Moulding by draught spring can make its be arranged in enlarged-diameter in the support plate recess (being centered around the groove (Eindrehung) on the fixing axle journal) within.Fixedly the head of axle journal and draught spring correspondingly are placed within the thickness size of support plate, and this is rendered as a kind of very flat structure type under situation to the simple more manually navigability of whole brake lining at the same time.

In Fig. 8, comprise a plurality of brake linings with set of pieces 101 of liner element 103, its with the matching relationship of the rubbing surface 105 of brake disc 106 that show, that for example be formed from steel on its circumference in show.Set of pieces 101 comprises liner element and their supporting slice 107 of supporting respectively.Have 9 such set of pieces 101 in an illustrated embodiment, they have 3 respectively and are designed to liner element 103 brake slipper, on supporting slice 107, just always have 18 liner elements.The liner element preferably is arranged to the ring sector in its gross area, as seen from Figure 8, and for example can be made by sintering metal.
In the embodiment according to Fig. 8,3 friction members or liner element are arranged on the supporting slice 107 in mode described below respectively.Applied supporting slice 107 for example has leg-of-mutton shape, wherein liner element 103 utilize the level of freedom of swing be hinged on supporting slice 107 on the side of the rubbing surface of brake disc.
According to Fig. 9 of the sectional view that has showed Figure 10 center line II-II, each liner element 103 is hinged on the supporting slice 107 by means of thread screw 109, dome 111, pressure spring 113 and nut 115.Thread screw 109 is arranged in the concentric space 117 of liner element 103, and with shown in mode extend through the perforation of dome and supporting slice, wherein under the situation of the intermediate support of pressure spring 113, reverse screw is set and connects by means of nut 115.In the space of the hull shape of dome 111 insertion supporting slices 107, the supporting of each liner element also just forms by spheric thrust bearing and ball collar.According to having schematically shown wherein Figure 11 of the guiding of any liner element on supporting slice 107, power FR plays the effect of frictional force and impacting force FA on the liner element, forms the F that makes a concerted effort thus.Always should make a concerted effort perpendicular to the sphere of spheric thrust bearing.On the surperficial center of gravity of the rubbing surface that is centered close to the liner element of radius r.Therefore F extends by the surperficial center of gravity of liner element necessarily with joint efforts; Just the liner element can be realized approximate constant surface pressure P with respect to the rubbing surface 105 of brake disc in this way.
According to liner base on the supporting slice 107 or liner element, illustrated being used to make the structure of impacting force homogenization be suitable in the same way independent, for example according to the structure of the support plate 107 on the liner bearing 119 of form illustrated in fig. 12.The liner susceptor design becomes support plate, is used for fixing the supporting slice 107 that schematically shows among Fig. 8.Here (Fig. 9) each supporting slice is again corresponding to screw 121, dome 123, pressure spring 125 and nut 127; Independent supporting slice 107 is correspondingly with as the identical mode of liner element, and the level of freedom of utilization swing property is placed on the liner bearing 119.Figure 12 has illustrated three supporting slices 107 on liner bearing 119 in underneath side elevation view, this supporting slice has 3 disposed thereon liner element respectively.
Liner bearing 119 has 18 liner elements of disposed thereon, and this liner bearing self can be installed in the liner support 129 shown in the view of rear end among Figure 13.The liner support has the eyelet 131 that is used for being suspended on the suspension connecting plate, and liner bearing 119 is bearing in it on the side of brake disc by the configuration that can contrast substantially.For this reason liner support 129 for example its according to underpart shown in Figure 13 on, being provided with can be by the bolt of spring clip 133 clampings, this bolt is deviating from the eyelet 135 that passes the liner bearing on the side of view shown in Figure 13, wherein other, can pass the opening of liner support from the extended fixed block (not shown) of liner bearing, and can be screwed with respect to the liner support.Therefore the liner bearing of the liner element with disposed thereon is disassembled from the liner support, this is because of after the said fixing element board is unclamped or after can being pulled out by the fixing bolt that spring clip clamps, and the liner bearing can be pulled out transverse to the liner support.
Supporting slice with liner element has been illustrated as according to Fig. 9 and 12 and has been fixed on the liner bearing, and wherein liner bearing self can be fixed on the liner support (Figure 13).Also design makes supporting slice directly be fixed on (Figure 14) on the liner support for certain application.
That be supporting slice independent liner element, that support them for the main feature that makes the surface pressure homogenization and their geometric configurations on supporting mass (liner bearing or liner support) according to liner of the present utility model supporting.In Figure 14 simple expression, in supporting slice directly fixing on the liner support as can be seen, be that independent set of pieces comprises 3 liner elements that supported by a supporting slice respectively, independent set of pieces has common center of gravity D1, D2 and the D3 as the transmission point of liner impacting force.The center of gravity D1 of 3 set of pieces 101, D2 and D3 form a triangle again, and its center of gravity S has formed half the power transmission point of total impacting force of each each liner of disk side.Can set out thus, can consider to make half liner on per 3 supporting slices, have each 9 liner element towards the both sides of medial axis 2.Therefore each total liner is provided with two center of gravity S.At these two center of gravity S places pressure spots of the correspondence of the loading transfer point of the brake lever 137 of Figure 14 shown in simple or hydraulic pressure or pneumatic brake piston (not shown).Preferably in the power delivery areas, that is to say that in the zone of center of gravity S space washer 138 is set respectively in this wise, and the similar pointwise ground of promptly can exerting all one's strength is delivered on the liner bearing from the liner support.Space washer 138 can design in liner bearing or liner support opposed facing on any face.The impacting force on the first half shown in Figure 14 and Lower Half (this impacting force equals half total impacting force of each liner respectively) that is delivered to total liner by brake lever 137 by structure recited above correspondingly by center of gravity S or D1, D2 and D3 are delivered in the supporting slice 107 equably, wherein supporting slice and liner element disposed thereon have the supporting structure that illustrates previously, thereby realize the homogenization of the surface pressure of total liner generally.Realize brake disc load (energy input constant, that pass through rubbing surface) more uniformly generally, and therefore reduced the danger that forms hot tearing.The important advantage of another one can find out in the braking characteristic of the sound that do not skirl of liner element, and this is because these liner elements are not because theirs have " (aufstellen) is installed " according to supporting of the present utility model.
Relate to the loading transfer on the liner support, therefore possible is, by globular hinge this loading transfer is set from the both sides of hold down gag, in other words respectively on the center of gravity of half liner, as top according to Figure 14 illustrated.The precondition that liner is divided into two and half liners when conducting the impacting force of half respectively is between two half parts of liner bearing (Figure 14) certain intrinsic movable property to be arranged.Figure 12 and 14 has represented, the Material weakening part that is formed by window or gap is set in the zone, medial axis of liner bearing or liner support in this wise, half part of liner bearing or liner support is swung limitedly with respect to center line, and this combines with the power transmission relevant with center of gravity and helps the homogenization of impacting force.Particularly advantageously according to the meaning of the transmission of impacting force be, come work by means of equalizer bar, this equalizer bar can be assigned to impacting force on two and half liners by common lever equably.At this, common lever extends concentrically with respect to liner bearing or liner support.
Each is expressed as hexagonal liner element in Fig. 9,10 and 12 can have other configuration, and they for example can be circular, as simple expression in Fig. 8 and 14.Though each supporting slice preferably is set 3 liner elements are arranged, its quantity also can change under following precondition respectively, i.e. the transmission of impacting force is facilitated and realized homogenization owing to the geometrical arrangements of center of gravity.Also can per 3 liner elements combination become a unique element; This is significant for liner material rubber chemical combination, organic for example.In Figure 15, represented such structure.Each half liner is provided with the liner element of three hearts, 6 liner elements altogether just, and they are fixed by supporting slice.As under the situation according to the mode of execution of Figure 14, supporting slice directly is arranged on the liner support swingably, wherein is again that the power of each half liner is delivered on the central center of gravity that single center of gravity constituted by 3 liner elements and carries out.
According to Figure 16, discrete component or liner element also can " hingedly similar " be arranged on the supporting slice, so for example connect by riveted joint, soldering point, connect or the like by screw.The Spacer 139 that is provided with in the mode of execution according to Figure 16 is inserted in respectively between liner element 101 and the supporting slice 107, and this Spacer allows essential restricted swing property, to be used to make the impacting force homogenization.Discrete component or same parts can certainly be designed to anti-(for example pin and the perforation) reversed.
Diagram among Figure 17 has been represented liner element 101 is fixed on the supporting slice 107 and supporting slice has been fixed on mode of execution on the liner bearing 119, and it is lower that this mode of execution obviously makes up ground with respect to the comparable view according to Figure 10.Also be provided with and thread screw 109 comparable dogbolts 141, it passes in the liner element respectively, in the dome 143 and the perforation in the supporting slice 107, wherein cup spring 145 is engaged in dogbolt after in this wise, and promptly the liner element shifts near the supporting slice place by spring force; Design the fixing and clamping of supporting slice in an identical manner with respect to the liner bearing.Advantage according to the layout of Figure 17 is, for the liner bearing is dismantled from the liner support, and need be with respect to the vertical motion of this liner support.The liner bearing can be after unclamping according to bolt clamp device shown in Figure 13 (unclamp same after) can be in the side or end face pull out.Therefore very simply be not dismantle liner support ground and unclamp the liner bearing, thereby can in the shortest time, carry out the complete replacing of liner bearing.Also passable is when needed independent liner element and/or supporting slice independent, that have fixed thereon liner element to be changed.This and known structure, the structure that promptly has a so-called dovetail slideway is compared has tangible advantage, in known structure, then the brake lining of single parts must be changed with its liner bearing after wearing and tearing, and be designed to reuse the liner bearing, and also reuse supporting slice under certain condition according to the brake lining of the utility model structure.
