Definitions
- the invention relates to a brake disc, in particular a brake disc for rail vehicles, with a hub part and a disc part which is detachably connected to the hub part.
- a brake disc of the type described above in which to compensate for thermal expansion movements in the radial direction, the disc part is firmly connected to the hub part via radial sleeve or bolt-shaped connecting elements arranged in the manner of a wheel spoke. Since the thermal expansion movements of the disc part that occur during each braking process lead to an increase in the diameter of the disc part relative to the hub part, the friction forces to be overcome in this construction are so high that the deformations which are detrimental to the effectiveness of the brake cannot be avoided.
- the invention is based on the object, starting from a brake disc of the type mentioned, to provide a solution which allows free movement of the disc part relative to the hub part to compensate for thermal expansion movements in the radial direction and at the same time the necessary positive locking between the hub part and the disc part in Circumferential direction is guaranteed.
- the hub part and the disk part are positively connected to one another, that a slight play is provided between the two parts, at least in the radial direction, and that several are distributed over the circumference between the hub part and the disk part, effective compression spring elements are arranged at least in the radial direction.
- effective compression spring elements are arranged at least in the radial direction.
- the play to be provided between the two parts must be provided so large that the heat-induced expansion movement occurring due to the highest temperature load occurring during operation is unhindered for the disc part.
- the compression spring elements themselves can contribute overall, at least in part, to the positive locking between the disk part and the hub part.
- the hub part is provided with a plurality of projections, which are distributed over the circumference and point radially outward, each having an axial recess, and that the disk part with a plurality, distributed over the inner circumference. is provided radially inwardly facing lugs, which are assigned to the lugs of the hub part and which each have an axial recess, and that the compression spring elements are each formed by cylindrical spring bushings, each of which is formed by the recesses of the lugs of the hub part and the disk part assigned to one another ⁇ are inserted.
- the positive connection is effected via the spring bushes.
- the recesses in the lugs of the hub part on the one hand and in the lugs of the disk part on the other hand can each be designed as semi-cylindrical recesses which, when assigned to one another, form a corresponding cylindrical bore which accommodates the spring bushings.
- the lugs of one part cover the lugs of the other part in the radial direction and that the recesses on the lugs of one part, preferably the hub part, as a bore and the recesses of the other
- the disk part are preferably designed as an elongated hole, the hole extending radially.
- the arrangement is such that the part of the elongated hole facing the disk part, together with the bore in the associated attachment of the hub part, form a cylindrical recess in the axial direction, so that in the attachment of the disk part the inserted spring sleeve is exposed to the inside and thus the radial expansion movement of the disk part taking place under the influence of temperature is possible without hindrance without the radial force effect of the spring element between the hub part and disk part being canceled.
- the approaches of the hub part are each designed as parallel approaches, each of which accommodates the associated approach of the disk part between them.
- At least one support ring that can be pushed onto the hub part is provided, which is provided with axially aligned support bodies that fill the space in the circumferential direction between adjacent approaches in the area on the hub side.
- the support ring is provided with securing fingers in the area of the lugs, which at least partially cover the end faces of the spring elements.
- the design can be made so that the support ring provided with support bodies, which is axially pushed onto the hub from one side, is assigned a corresponding smooth mounting ring on the other side, which in turn is provided with corresponding securing fingers, so that the Recesses can go smoothly in the axial direction, which simplifies processing.
- two support rings are provided, which bear against the shoulders of the hub part on both sides and which can be connected to one another are.
- the support body of the two support rings can be designed in the axial direction so that the support body of one support ring complements the support body of the other support ring.
- So-called ventilated brake discs both for rail vehicles and for land vehicles, have a disc part which is formed from two parallel ring discs, the inner circumference of which ends at a distance from the hub part and forms air inlet openings and which are connected to one another via radially running transverse webs, the
- the problems of disc warping due to thermal expansion in the case of ventilated brake discs of the above type can be additionally favorably influenced if a guide means is arranged on the outer circumference, through which a lateral outlet slot is formed, so that the radially outflowing cooling air follows at least one side is deflected in the axial direction.
- a guide means is arranged on the outer circumference, through which a lateral outlet slot is formed, so that the radially outflowing cooling air follows at least one side is deflected in the axial direction.
- the inventive arrangement of the guide means on the outer circumference of the brake disk ensures that at least the airstream cannot act on the cooling air ducts in the opposite direction to the cooling air flow. This then ensures, however, that the cooling air can flow undisturbed regardless of the constantly changing position of the individual cooling air duct in relation to the airstream, so that overall, even at high driving speeds, the brake disc is more uniformly cooled than was previously possible.
- the guide means can be arranged in such a way that the cooling air flows out only on one side - essentially axially - or that the cooling air can flow out axially on both sides.
- the guide means can be cast on directly in the case of cast brake disks. In an advantageous embodiment of the invention, however, it is also possible to form the guide means by means of an attached sheet metal profile.
- a further favorable influence by the cooling air is achieved if the air inlet openings on the inner circumference of the annular disks are each provided with covers, each of which has a plurality of cooling air inlet openings distributed over the circumference.
- the cooling air passage can be coordinated by appropriate dimensioning of the cross section of the cooling air inlet openings.
- deflection means are assigned to the cooling air inlet openings on the inside of the cover in each case Deflect incoming cooling air from its axial inlet direction into the radial cooling air ducts. Since there is no impact loss and turbulence as a result of the targeted deflection, braking performance from high speeds results in significantly better cooling performance and thus improved braking performance.
- two adjacent transverse webs are connected to one another via at least one additional web aligned in the circumferential direction, which divides the cooling air duct formed between two transverse webs.
- This arrangement has the advantage, in particular for brake discs on rail vehicles, in which the cooling air ducts have relatively large cross sections in terms of dimensions, that the available heat transfer area per cooling air duct is increased and the contact between cooling air and the heat transfer surfaces is improved by the subdivision of the cooling air duct .
- a brake disk designed in this way can be used both for a brake disk of the type according to the invention constructed from two parts and for ventilated brake disks of the conventional type.
- the additional web increases in thickness in cross-section, at least over part of its radial extent, from the inside to the outside.
- This measure can be used to influence the design of the free flow cross section of each cooling air duct, in order firstly to adapt the change in cross section predetermined by the circular shape between the inner circumference of the annular disc and the outer circumference of the annular disc to the flow processes in the cooling air duct and also to increase the volume the amount of air flowing through the cooling air duct due to the amount of heat.
- the cross section of the Additional web can be designed so that it initially increases from the inner circumference and decreases again towards the outside.
- ventilated brake discs result in an additional reduction in heat distortion.
- they represent advantageous improvements to such ventilated brake discs in which the disc part is rigidly connected to the hub part, ie there is no radial play between these two parts.

- Fig. 2 is an axial section corresponding to the
- FIG. 3 shows another embodiment of a brake disk in a side view, partly in section along the line III-III in FIG. 4,
- Fig. 4 shows a section. the line IV-IV in
- Fig. 3, 5 shows a modified embodiment of the brake disc according to FIG. 3 in an axial section along the line VV in FIG. 3,
- Fig. 6 is a compression spring element in the form of a
- FIG. 8 shows a partial section through a rigid brake disk with two-sided air outlet.
- FIG. 1 of a brake disc for a rail vehicle essentially consists of a hub part 1 and a disc part 2, which can be released in a form-fitting manner with? are connected.
- the hub part 1 is provided with a plurality of lugs 3 which are distributed over the outer circumference and point radially outwards.
- the pane part 2 is accordingly provided with a plurality of projections 4 which are radially inward and distributed over its inner circumference.
- the hub-side lugs 3 are provided on their ends facing the disk-side lugs 4 on both sides with circumferential side webs 5 which laterally support the disk-side lugs 4 in the axial direction on both sides.
- the end face 6 of the hub-side lugs 3 arranged between the two side webs 5 is part of a cylindrical face related to the central axis of the disks.
- the end face 6 facing the corresponding end face of the disk-side lugs 4 is in this case correspondingly part of a cylindrical surface, so that the hub part 1 and the disk part 2 can be rotated relative to one another, with a slight radial play being present between these two end faces.
- the hub-side lugs 3 and the disk-side lugs 4 are each provided with a recess 7, each of which is present as a half cylinder in the hub-side lug 3 and as a half cylinder in the disk-side lug 4 is.
- a so-called heavy-duty clamping sleeve is inserted into this recess 7 as a compression spring element 8.
- a heavy-duty clamping sleeve essentially consists of a hollow cylindrical steel body which is slotted at one point on its circumference.
- the slot can be arranged exactly axially or obliquely from both end faces to the center, so that there is an approximately "arrow-shaped" slot contour.
- the slot can also be arranged in a helical shape.
- the heavy-duty clamping sleeve is under
- Bias is pressed into the cylindrical recess 7 so that it acts as a compression spring element in the radial direction to the outside.
- the heavy-duty clamping sleeve then absorbs the braking torque in the circumferential direction.
- the disk part is designed as a so-called ventilated disk, in which two parallel annular disks 9.1 and 9.2 are connected to one another via transverse webs 10, so that a cooling air duct 11 is formed between each two adjacent transverse webs 10.
- the brake disc is fixedly connected via its hub part to the axle of a wheel set of a rail vehicle, for example via a so-called pressure oil assembly.
- the disk part When braking, especially in the case of fast-moving rail vehicles, the disk part heats up to a considerable extent as a result of the frictional heat, so that there is a corresponding increase in diameter. Since the disk part 2 with the hub part 1 via the mutually assigned hub-side lugs 3 and the disk-side lugs 4 only via the positive connection by means of the compression spring elements 8 is connected, the disk part 2 can expand freely in the radial direction, the heavy-duty clamping sleeves serving as compression spring elements 8 providing the necessary centering. The distortions which are still possible in the prior art in the case of such a heat-induced expansion movement are avoided here.
- the secondary part 1 is provided with two lugs 3.1 and 3.2 which run parallel to one another and which accommodate the disk-side lug 4 between them.
- the two hub-side lugs 3.1 and 3.2 are provided with a continuous cylindrical recess 7, while the disk-side lug 4 located between the two hub-side lugs 3.1 and 3.2 extends almost to the hub part 1 and is here provided with a recess which faces the hub part is open, so that the disc-side extension 4 has an approximately fork-shaped shape.
- Compression spring element 8 in the form of a heavy-duty clamping sleeve.
- the arrangement is such that the heavy-duty clamping sleeve 8 is pressed into the recess 7 under pretension and in this case also exerts a radially acting spring force on the recess 4 in the disk-side extension 4, provided the recess is appropriately designed.
- FIG. 3 has essentially the same structure as that described with reference to FIG. 2
- Embodiment matching components are provided here with matching reference numerals.
- the Difference of the embodiment acc. 3 for the embodiment according to FIG. Fig. 2 is that the disk-side extension 4 is provided with an elongated hole 12 instead of a fork-shaped design, so that here the radial play required by thermal expansion movements is given.
- the arrangement is such that here too the compression spring element 8, designed as a heavy-duty clamping sleeve, with its peripheral surface 13 facing the disk part 2 presses against the reveal of the end of the elongated hole 12 facing the disk part 2.
- the force occurring during the braking process and acting in the circumferential direction on the compression spring element 8 designed as a heavy-duty clamping sleeve is not or only to a small extent from
- Compression spring element 8 added.
- the force in the circumferential direction is transmitted directly via the free end of the disc-side attachment 4 to the hub-side attachments 3 adjacent in the circumferential direction.
- a support ring 14 is provided, which in each case in the associated interspaces between two adjacent radial projections
- the support ring 14 is provided in the area of the associated lugs 3 with a securing finger 17 which covers the respective recess on the outside and thus secures the compression spring element 8 contained in the recess.
- the arrangement can be designed in such a way that a support ring 14 is connected in one piece to the corresponding support bodies 15 and can thus be pushed in laterally and completely penetrate the support space between two adjacent approaches.
- a counter ring 14.1 is then provided from the other side, which is screwed to the support ring 14 via the support body 15, so that the arrangement is axially secured overall.
- the arrangement can also be such that two support rings with support bodies 15 are provided, which are inserted alternately from one side and from the other, so that each support ring is provided with a corresponding support body 15 only for every second support space.
- the cooling channels 11 formed by the transverse webs 10 are each divided in the circumferential direction by an additional web 18.
- This additional web provides better guidance of the cooling air flowing radially from the inside out through the cooling air channels 11 , which in particular ensures better contact of the cooling air with the annular disks 9.1 and 9.2 and thus leads to better heat dissipation.
- D: .e additional webs 18 are expediently designed in cross-section at least over part of their radial extent so that their cross-section increases in thickness from the inside to the outside.
- the cooling air ducts 11 have an increasing cross-section from the inside to the outside, which at least in the inlet area up to about half the duct length reduces the flow velocity of the air and thus would lead to an increase in flow resistance.
- This is counteracted by the additional webs 18.
- the inner surfaces 19 of the annular disks 9.1 and 9.2 can also be spherical in cross-section to improve the flow guidance, ie to reduce the flow resistances, so that an optimal cross-sectional shape from a flow point of view can be achieved here .
- FIG. 5 shows a further configuration of the brake discs which improves the cooling air flow.
- a guide means 20 is arranged on the outer circumference of the annular disks 9.1 and 9.2 and extends over the entire circumference of the disk.
- This guide means 20 can be formed by a sheet metal profile, which is attached subsequently, for example on an outwardly protruding extension 21 of the additional web 18 or directly on the edges of the transverse webs 10 in brake disks without such an additional web.
- This guide means 20 serves to laterally deflect the air flowing through the respective cooling air ducts on the outer circumference in accordance with arrow 22.
- the main advantage of arranging such a guide means over the embodiment according to. Fig. 4, however, is that, especially at high speeds, the ambient air does not act directly on the crosspieces 10 and can thus impair the free outflow of the heated cooling air.
- annular air inlet openings 24 Since the spaces between the inner circumference of the annular disks 9.1 and 9.2 and the hub part 1 each form annular air inlet openings 24, the cross section of which is determined solely by the structural dimensions, it is expedient for a coordination of the cooling air quantities flowing through if respectively annular ones Covers 25 are arranged, which are provided with cooling air inlet openings 26 with a defined cross section, and which are each assigned to the spaces between the lugs 3, 4.
- a better and more uniform cooling air flow does not only mean an improved cooling performance. It is therefore possible, with a constant requirement for the cooling capacity compared to the previous brake disc shapes, to reduce the amount of cooling air flowing through per unit time by appropriately dimensioning the covers 25 with deflecting center 27. When used on high-speed trains, however, this means a significant reduction in the loss of traction drive power, since it must not be overlooked that each brake disc also acts as a radial pump wheel for the constantly flowing cooling air and has a corresponding energy consumption which the locomotive also has to provide is.
- FIG. 6 shows a perspective illustration of an embodiment for the heavy-duty clamping sleeve used here preferably as compression spring element 8.
- the brake disc shown only schematically in FIGS. 7 and 8 essentially consists of a hub body 1, which is connected to a disc part 2, on which the brake pads, not shown here, connected with so-called calipers during the braking process to the system come.
- the brake disc 2 consists essentially of two brake discs 9.1 and 9.2, which are connected to one another via a plurality of radially extending crosspieces 10, through which radially directed cooling air ducts are formed between the annular discs.
- a guide means 20 is provided which extends beyond the outer circumference of the annular disks 9.1 and 9.2 and extends over the entire circumference of the disc.
- This guide means 20 can be cast in one piece on one of the ring disks during the casting process, or can be subsequently connected to one of the ring disks as an additional profile, for example as a preformed sheet metal profile.
- This guide means 20 serves to laterally deflect the cooling air flowing through the respective cooling air channels in accordance with arrow 22 on the outer circumference.
- the main advantage of the arrangement of such a guide means compared to conventional brake disks is that, especially at high speeds, the ambient air does not act directly on the transverse webs 10 connecting the annular disks, and the airstream does not impair the free outflow of the cooling air can.
- the guide means 20 can only deflect the outgoing cooling air to one side. However, it is also possible - as shown in FIG. 8 - to provide a profile for the guide means, which deflects the cooling air flowing off to both sides. In both cases, the guide means 20 can consist of a sheet metal profile, which is connected, for example, to the crossbars 10 by welding.
