Specific embodiments
In order more clearly to represent structural feature, purpose of design and the use advantage of patent brake lining of the present invention, now in conjunction with picture, embodiment is carried out to specific design explanation.
Fig. 1,2 for the present invention a kind of can automatic attaching bullet train brake pad front elevation and the rear view of friction, as shown in the figure brake pad of the present invention mainly by brake pad 1 (1 ＇, 1 ＇ ＇), resilient key 2, support 3, backboard 4 is installed and can be formed by gripping jump ring 5.
The brake pad of brake lining of the present invention is three of interior China and foreign countries arcuation and distributes, and outer arc has two large brake pads and six friction pieces, and middle arc has four large brake pads, two friction pieces, and inner arc has four friction pieces.The solid construction of atresia centered by large brake pad wherein and friction piece are equal, their parallelogram that was shaped as down angle.The object that brake pad shape is designed to solid parallelogram sturcutre is: 1. the solid design of removing center hole is the continuity in order to ensure friction material, avoids around hole, occurring hot crack under the effect of thermal cycling stresses and finally causes brake lining to fall piece phenomenon; Removing center hole can ensure under the prerequisite of useful area simultaneously, reduce the boundary dimension of brake pad, increase the gap between brake pad, strengthened heat loss through convection ability, the ice and snow silt that reduces to be involved at the bottom of metal raw-silk waste and car in braking process stops up the probability in brake pad gap; 2. the gap that brake pad shape is designed to parallelogram shape and is between the brake pad in order to ensure interior outer-loop is parallel to fricting movement direction generally, be conducive to like this being taken out of of the slag inclusiones such as ice and snow silt under the effect of frictional force, in the situation that there is no slag inclusion, be conducive to passing through of airflow smooth simultaneously.Therefore brake pad is solid parallelogram shape, be conducive to ensure brake pad integrity, reduce brake disc surface abnormal wear and effectively reduce brake disc surface temperature.
Brake pad is divided into again large brake pad 1 and two kind of friction piece 1 ＇, 1 ＇ ＇ by shape and mounting point difference, and two kinds of friction pieces become mirror image symmetry.The composition structure of three kinds of brake pads is consistent, and brake pad is made up of friction material 1-1, mezzanine 1-2 and connecting pin 1-3 as shown in Figure 3.Shown in Fig. 4,4.1,5,5.1,6,6.1, each brake pad mezzanine forms structural similarity, therefore describe as an example of the mezzanine 1-2 of large brake pad example, the mezzanine 1-2 of a brake pad dorsad side of friction material 1-1 has hemispherical projections 1-2-1, its top is plane 1-2-2, there is a through hole 1-2-3 at center, in the one side of mezzanine 1-2 connection friction material, has a counterbore 1-2-4 coaxial with through hole 1-2-3, and counterbore 1-2-4 is for riveting pin 1-3.The plate body part of mezzanine has six through holes.Connecting pin 1-3 is multidiameter shaft shape as shown in Figure 7, and afterbody has an annular slot 1-3-1, and connecting pin header planes has a hole 1-3-3, for riveting flange.The concrete package assembly of brake pad is: connecting pin cylinder 1-3-2 is from mezzanine 1-2 brake pad one side insertion mezzanine through hole 1-2-3 dorsad, the mode that utilization presses is riveted in counterbore 1-2-4, ensures connecting pin large footpath left surface and mezzanine back convex plane 1-2-2 laminating.After mezzanine 1-2 and connecting pin 1-3 rivet, then reach metallurgy combination by carrying out sintering after mezzanine and friction material compacting.Friction material is in the time suppressing with mezzanine, and friction material is inserted on mezzanine plate body in the hole two holes of 1-2-5, and hole 1-2-5 is for location.The friction piece 1 of Fig. 5, Fig. 6,, 1,, the mezzanine 1-2 structural similarity of mezzanine and large brake pad, the hole 1 on mezzanine body ,-2-5,1 ,-2-6,1, ,-2-5,1, ,-2-6 should not insert friction material, for location.
As shown in Fig. 1,1.1,8,8.1, roundlet pin 3-2 in the hemispherical projections at support 3 backs is inserted to the counterbore 4-4 that backboard recess 4-3 bottom is installed, make the protruding 3-1 of support 3 form sphere-contact with the recess 4-3 that backboard 4 is installed, the paracentral locating stud 3-3 in the end post of support 3 inserts the 4-5 positioning through hole of installing on backboard 4, restriction support 3 big angle rotaries.Subsequently resilient key 2 is inserted to the location blind hole 3-7 on support 3, form interference fit with blind hole.Carry out subsequently the installation of brake pad.
Brake pad mount scheme is as shown in Figure 1: friction pieces 1 are installed at support 3 triangle tops, or 1, a support 3 triangle bottom bipod large brake pad 1 of each installation and friction pieces 1, or 1, and friction piece 1 is installed in support 3 relevant positions that backboard upper half part is installed,, friction piece 1 is installed in lower half portion support 3 relevant positions,.
To be arranged on the friction piece 1 at support triangle top, be installed as example, as Fig. 1, 5, 7, shown in 8 by friction piece 1, connecting pin 1-3 afterbody insert the through hole 3-6 of conical surface 3-5 bottom under the recess of support 3 and the through hole 4-5 on backboard 4 be installed, make friction piece 1, mezzanine 1,-2 projections 1, the recess hemisphere face 3-4 of-2-1 and support 3 forms sphere-contact, again resilient key 2 is inserted to friction piece 1, mezzanine 1, positioning hole 1 on-2,-2-6, restriction friction piece 1, significantly rotate and (be positioned at the friction piece 1 of support triangle bottom, when installation, resilient key 2 inserts friction piece 1, mezzanine 1, positioning hole 1 on-2,-2-5).Finally clamp two trip ring 5-1 of jump ring 5 with needle-nose pliers, make the perforate direction of jump ring 5 aim at friction piece 1, connecting pin 1,-3 draw-in grooves 1 ,-3-1, pushes jump ring the counterbore 4-1 that backboard is installed, the interior ring 5-2 of jump ring blocks friction piece 1, connecting pin 1-3 draw-in groove 1-3-1.The same the carrying out of installation of all the other brake pads and support, completes brake lining integral installation.
The all those skilled in the art of final statement are not having under own originality design work, and the case study on implementation of all similar and the present embodiment obtaining, all belongs to the scope of protection of the invention.
Every meet the spirit of a kind of bullet train brake pad structure that can automatically adjust laminating friction of this patent and do not depart from this patent embodiment technological scheme scope all belong to this patent protection domain.
