Fig. 1 represents the friction block of brake disk 10 of embodiment of the present invention.This friction block of brake disk 10 is used in the disk type braker of high-speed railway vehicle, disposes a plurality of along the sense of rotation of disk type braker (omit diagram).As shown in Figure 1, friction block of brake disk 10 has substrate 12, is installed on the brake lining 14 on this substrate 12.
Described substrate 12 sees on the plane and constitutes the planar that has along the elongated shape of prescribed direction extension that the two end part of its length direction form general triangular respectively.This substrate 12 is with the attitude setting of its length direction along the brake disc sense of rotation.
As shown in Figure 2, on substrate 12, be provided with a plurality of through holes 16 that connect along the thickness of slab direction.This through hole 16 is located on the position that described brake lining 14 is set, and through hole 16 is with the quantity formation of the brake lining 14 of installation.Each through hole 16 forms underpart among its Fig. 2 by the shape of hole enlargement.
Around each through hole 16 in the front (face of the upside of Fig. 2) of the substrate 12 of arrangement brake liner, be formed with curved shoe 18 respectively with concavity flexure plane.These curved shoe 18 planes see that the recess by circle constitutes, and the flexure plane above it becomes seat surface 18a.Central authorities in this curved shoe 18 form described through hole 16 respectively.
As shown in Figure 1, described brake lining 14 is removed at the two end part of the length direction of substrate 12, arranges two row on width direction, then respectively disposes one on the two end part of substrate 12.The state configuration of each brake lining 14 to be separated from each other.In addition, be expressed as two row in the legend and arrange, also can be by the diameter that reduces brake lining 14 on width direction assortment three row.
As shown in Figures 1 and 2, each brake lining 14 forms discoideus.Omit diagram, each brake lining 14 is omitted diagram, and it is polygon-shaped to form triangle, pentagon, Hexagon etc., at this moment, also can form the curved surface shape that makes the top corner part slyness.
The front of brake lining 14 (leaving the end face of substrate 12 1 sides) becomes the pushing surface 20 that is pressed on the brake disc.(thickness of slab direction) connects the through hole 22 of central part about being formed with respectively on these each brake lining 14.This through hole 22 is relative with the through hole 16 of substrate 12.
Each through hole 22 forms the formation of the band step hole of path by substrate 12 sides, forms minor diameter part 22b and large-diameter portion 22c across stepped part 22a.Minor diameter part 22b is formed at substrate 12 sides of stepped part 22a, and large-diameter portion 22c is formed at pushing surface 20 sides.
Each brake lining 14 has the cylindrical portion 26 that forms certain thickness roughly and the main part 24 that can constitute with the brake disc butt and extend to substrate 12 from this main part 24.Be formed with described through hole 22 on main part 24, cylindrical portion 26 is surrounded described through holes 22 and is formed on the lower end surface of main part 24, and relative with described curved shoe 18.
The front-end face of cylindrical portion 26 (lower end surface) 26a forms the flexure plane of the convex corresponding with the bottom surface 18a of the curved shoe 18 of substrate 12.In other words, the front-end face 26a of cylindrical portion 26 axle center that forms cylindrical portion 26 becomes the arc surface of rotating center.And brake lining 14 forms the gap between the bottom surface 18a of the front-end face 26a of cylindrical portion 26 and curved shoe 18.Can be when thus, the front-end face 26a of cylindrical portion 26 is on abutting to the bottom surface 18a of curved shoe 18 with the state of this butt along curved shoe 18 displacements.
The combination of described substrate 12 and brake lining 14 by the rivet 30 of one of holding member example.This rivet 30 has the head 32 that is used for anti-avulsion and the diameter main part 34 less than this head 32.Rivet 30 is inserted logical the stride across through hole 16 of described substrate 12 and the through hole 22 of brake lining 14.
The diameter of head 32 is less than the large-diameter portion 22c of the through hole 22 of brake lining 14, and has the external diameter bigger than the diameter of minor diameter part 22b.The lower end surface of head 32 from the top be connected to brake lining 14 through hole 22 stepped part 22a above (bearing surface).Thus, brake lining 14 is by rivet 30 and by anti-avulsion.
Main part 34 have and the abutting part 34a of substrate 12 butts and be disposed at head 32 and abutting part 34a between intermediate portion 34b.
Intermediate portion 34b has diameter than head 32 and the little external diameter of abutting part 34a.In other words, abutting part 34a constitutes the diameter bigger than intermediate portion 34b.
Abutting part 34a has the diameter external diameter littler than head 32, curved shoe 18 butts of the underpart of this abutting part 34a and substrate 12.
Be provided with joint 36 on main part 34, its underpart from abutting part 34a is extended downwards and is configured in the through hole 16 of substrate 12.The bottom of this joint 36 is sandwiched substrate 12 by bottom and the abutting part 34a that utilizes this joint 36, thereby rivet 30 is fixed on the substrate 12 by hole enlargement.
32 lower end surface is longer slightly than the distance to the front end of cylindrical portion 26 above stepped part 22a to the distance of the lower end surface of abutting part 34a from the head.Thus, under brake lining 14 and state that substrate 12 combines, between the bottom surface 18a of the front-end face 26a of cylindrical portion 26 and curved shoe 18, be formed with small gap.
Gap width S1 between abutting part 34a and the cylindrical portion 26 forms less than the gap width S2 between the inner peripheral surface of the large-diameter portion 22c of head 32 and through hole 22.This be because, when brake lining 14 tilts, abut on the outer circumferential face of head 32 at the inner peripheral surface of through hole 22 before, the inner peripheral surface of cylindrical portion 26 abuts on the outer circumferential face of abutting part 34a.
Between substrate 12 and each brake lining 14, be respectively equipped with elastic member 40.As shown in Figure 3, each elastic member 40 is made of metal disc spring respectively, is the parts that the bottom surface forms the plate-like of opening portion 40a.Elastic member 40 is inserted under the state that leads to this opening portion 40a in cylindrical portion 26 and is configured between substrate 12 and the brake lining 14.
Between brake lining 14 and elastic member 40, dispose and suppress conducting-heat elements 44.This inhibition conducting-heat elements 44 sees to have with the identical shaped and big or small sheet material of substrate 12 by the plane and constitutes, this inhibitions conducting-heat elements 44 each brake lining 14 of leap and being provided with.In addition, owing to dispose substrate 12, so direct representation substrate 12 not among Fig. 1 at the back side that suppresses conducting-heat elements 44.
Suppressing conducting-heat elements 44 has with the contacting part 44a of the corresponding respectively setting of each brake lining 14 and is located at extension part 44b between these contacting parts 44a.Each contacting part 44a is the position that forms ring, and it has the internal diameter that diameter is a bit larger tham cylindrical portion 26, and has the external diameter with the roughly the same diameter in upper end portion of elastic member 40.Suppress conducting-heat elements 44 and insert the state configuration of the opening that leads to its contacting part 44a below brake lining 14 with cylindrical portion 26.And contacting part 44a is contacted with brake lining 14.
Suppressing conducting-heat elements 44 is made of the material of pyroconductivity less than brake lining 14.Suppressing conducting-heat elements 44 is made of the sheet material that for example constitutes the low stainless steel of the cast iron at position (underpart) of substrate 12 sides of brake lining 14 by thermal conductivity ratio.
In the friction block of brake disk 10 of present embodiment, be provided with the whirl-stop device 48 of brake lining 14.This whirl-stop device 48 is made of with the card complex hole 51 of being located at the engagement groove (recess) 50 on the brake lining 14 and be located on the substrate 12 pin 49 that is configured between substrate 12 and the brake lining 14.That is, engagement groove 50 and card complex hole 51 relative configurations, pin 49 upper end portion is inserted in the engagement groove 50, is inserted in the card complex hole 51 and sell 49 underpart.Thus, pin 49 engages with the inner peripheral surface of engagement groove 50 and the inner peripheral surface of card complex hole 51, the rotation of prevention brake lining 14.
On inhibition conducting-heat elements 44, be provided with and make described pin 49 insert logical inserting hole 44c.Be disposed between substrate 12 and the brake lining 14 owing to suppress conducting-heat elements 44, the two is gone up and slotting leading to sells 49 so this inserting hole 44c can make pin 49 be bonded on substrate 12 and brake rim 14.
The following describes the action of the friction block of brake disk 10 of above formation.
In this friction block of brake disk 10, when brake lining 14 was not pressed against non-braking maneuver on the brake disc, the elastic force of brake lining 14 by elastic member 40 remained between the curved shoe 18 of cylindrical portion 26 and substrate 12 and forms gapped state.At this moment, the stepped part 22a of the through hole 22 of brake lining 14 engages with the head 32 of rivet 30, so brake lining 14 does not break away from from substrate 12.
When brake lining 14 is pressed against on the brake disc (during braking maneuver), the identical state of state when keeping with non-braking maneuver, become and the equal value of the elastic force of elastic member 40 up to this pressing force, but become greater than the elastic force of elastic member 40, then elastic member 40 resiliently deformables as if pressing force.By the resiliently deformable of this elastic member 40, brake lining 14 moves to the direction near substrate 12.
Under the inhomogenous situation of brake lining apparent height when new product, only outstanding brake lining 14 is pushed to brake disc, but by the brake lining that makes and should be outstanding 14 corresponding cylindrical portion 26 and curved shoe 18 butts, plastic deformation takes place because of big distortion in the elastic member 40 that can prevent this braking substrate 14, and the reduction of the elastic force after preventing.Because by butt, the front-end face 26a of cylindrical portion 26 is along the bottom surface 18a displacement of curved shoe 18, brake lining 14 tilt displacements thus.At this moment, because the gap width S1 between abutting part 34a and the cylindrical portion 26 forms less than the gap width S2 between the inner peripheral surface of the through hole 22 large-diameter portion 22c of head 21 and brake lining 14, so the inner peripheral surface of cylindrical portion 26 and the outer circumferential face butt of abutting part 34a, and keep this state.In addition, even under the situation that brake lining 14 tilts, because stepped part 22a engages with the head 32 of rivet 30, brake lining 14 is (direction of leaving from substrate 12) displacement not further not upward also.When braking maneuver, being situated between between brake lining 14 and elastic member 40 has the conducting-heat elements 44 of inhibition, so transmit to elastic member 40 even brake lining 14, also can suppress its heat owing to the friction with brake disc heats up.
As described above, according to the present invention,, also can suppress its heat and transmit to elastic member 40 even brake lining 14 is owing to the friction with the braking wiping heats up when braking maneuver.Its result can make elastic member 40 be difficult to intensification, can suppress elastic member 40 annealing thus easily and be warming up to the flexible temperature of forfeiture, can prevent elastic member 40 forfeiture elasticity.And,, can improve the life-span of brake lining 14 because brake lining 14 can press liter so can reduce local face by elastic member 40 along brake disc tilt displacement and mobile.
Particularly in the present embodiment, in order to be difficult to directly from brake lining 14 to extension part 44b heat conduction, the contacting part 44a that suppresses conducting-heat elements 44 can emit the heat that directly is subjected to from brake lining 14 to extension part 44b, can suppress the intensification of the contacting part 44a of conducting-heat elements 44.Its result can effectively suppress the intensification of the elastic member 40 that contacts with contacting part 44a.
In addition, in the present embodiment, just suppress conducting-heat elements 44 and be provided with one as a whole, can reduce the installation work-hour that suppresses conducting-heat elements 44.And, in the present embodiment, because adjacent brake lining 14 spaces configuration, between this brake lining 14, also dispose the extension part 44b that suppresses conducting-heat elements 44, so in this extension part 44b, can carry out heat insulation to heat and heat radiation, can suppress the intensification of elastic member 40 more effectively from brake lining 14.
In the present embodiment, owing to utilize elastic member 40 to push brake lining 14, engage with the head 32 of rivet 30 by the stepped part 22a that makes the through hole 22 that is formed on the brake lining 14 on the other hand, prevent the disengaging of brake lining 14, so can allow the displacement of brake lining 14 by elastic member, elastic force by this elastic member 40 does not break away from brake lining 14 from substrate 12 simultaneously, and substrate 12 is engaged reliably with brake lining 14.
In the present embodiment, because only the brake lining 14 to regulation acts under the overladen situation when braking maneuver, the cylindrical portion 26 of its brake lining 14 and curved shoe 18 butts of substrate 12, so elastic member 40 can not deform until the plastic deformation zone, and can make brake lining 14 according to the action direction of suffered power and tilt displacement.
In addition, in the present embodiment, be provided with near substrate 12, can be reduced in the flexural stress that produces on the rivet 30, the pathization that can seek rivet 30 thus by abutting part 34a with big shearing stress and the crooked firmly rivet 30 of effect.
In addition, in the present embodiment,, can avoid brake lining 14 and suppress conducting-heat elements 44 wearing away along with the rotation of brake lining 14 owing to be provided with the whirl-stop device of brake lining 14.
In the present embodiment, brake lining 14 has main part 24 and cylindrical portion 26, also can replace this structure, and as shown in Figure 4, brake lining 14 formation have roughly certain thickness tabular.In this structure, on substrate 12, be not provided with curved shoe 18, elastic member 40 is directly inserted under the state that leads to its opening portion 40a at rivet 30 and is disposed between substrate 12 and the brake lining 14.
The contacting part 44a that suppresses conducting-heat elements 44 forms so circular, and it has the diameter internal diameter bigger slightly than the main part 34 of rivet 30, and have and the upper end portion of elastic member 40 roughly with the external diameter in footpath.Rivet 30 direct inserting are led on contacting part 44a.
When braking maneuver, become greater than the elastic force of elastic member 40 as if pressing force, then elastic member 40 resiliently deformables.By the resiliently deformable of this elastic member 40, brake lining 14 moves to the direction near substrate 12, and perhaps brake lining 14 tilts.Promptly, according to the installment state of friction block of brake disk 10 and the state of wear of brake lining 14 etc., brake lining 14 tilts under the inhomogeneous stressed situation in the whole surface of brake lining 14, and brake lining 14 keeps its postures parallel mobile to substrate 12 sides under the even stressed situation in the whole surface of brake lining 14.At this moment, bear the pressing force of brake lining 14 by the elastic force of elastic member 40.
In this variation,, be warming up to the flexible temperature of forfeiture so can suppress elastic member 40 easily owing to can make elastic member 40 be difficult to heat up.And, because reaching along the brake disc tilt displacement by elastic member 40, brake lining 14 moves, press liter so can reduce local face, can improve the life-span of brake lining 14.
In described mode of execution and variation, form the integrative-structure of crossing over each brake lining 14 with suppressing conducting-heat elements 44, but also can replace this structure, on each brake lining 14, be provided with and independently suppress conducting-heat elements.
In addition, in said embodiment, the extension part 44b that suppresses conducting-heat elements 44 leaves from brake lining 14, but is not limited thereto, and extension part 44b also can contact with brake lining 14.Just, aspect the intensification that effectively suppresses extension part 44b, extension part 44b preferably leaves from brake lining 14.
