Abstract
The utility model relates to a high-speed train braking plate with a fixed chassis, comprising the fixed chassis (4), a friction disk (3-1) and a brake mounting plate (3-2), wherein the friction disk (3-1) is fixed on the brake mounting plate (3-2) fixedly connected with the fixed chassis (4); a groove (6) is arranged on the fixed chassis (4) along the length. The utility model has the advantages of reducing the deformation, reducing the braking force loss caused by overcoming the deformation, easily dismounting the plate for replacement, enabling the braking plate to contact a brake disk under flat situation to prevent the braking disc from peeling and pitting due to uneven stress distribution, avoiding low braking force.
Description
Technical field
The utility model relates to the high-speed train braking technical field, specifically, relates to a kind of bullet train brake lining with fixed underpan.
Background technique
Along with the trend of train, train braking is had higher requirement to high speed development.Brake lining causes the brake lining bending, and is difficult for recovering being out of shape serious problem owing to bearing alternating stress and high heat load in the braking at a high speed, influences retardation efficiency on the one hand, dismantles relatively more difficult on the other hand.The brake pad that uses all is made up of sintered alloy friction material, brake lining mounting plate and fixed underpan at present, the brake lining mounting plate and the fixed underpan of brake lining are used carbon steel more, reason owing to linear expansion, fricative heat can cause fixed underpan and brake lining integral body to deform, the long-term use, above-mentioned distortion can cause fixed underpan and brake lining generation plastic deformation.Because this distortion, the pressure that brake lining affacts on the brake disc can produce deviation.The problem that disassembles from the arm of braking clamp appears when changing brake lining simultaneously being difficult to.
Summary of the invention
The purpose of this utility model provides a kind of can the mitigation is out of shape, and reduces braking force because of overcoming the loss that distortion causes, the bullet train brake lining of the band fixed underpan of convenient disassembly during replacing.
The technological scheme that realizes above-mentioned purpose is: a kind of bullet train brake lining with fixed underpan, form by fixed underpan, friction plate and brake lining mounting plate, friction plate is fixed on the brake lining mounting plate, and the brake lining mounting plate is fixedlyed connected with fixed underpan, in the length direction crosscut of fixed underpan groove is arranged.
After adopting technique scheme, by fixed underpan brake lining is fixed on the braking clamp, the frictional heat that clamp when braking produces and the brake pad that causes and the distortion of fixed underpan, the groove of crosscut is separated on the chassis length direction that is fixed, and can reduce the amount of deformation of integral body.Reduced amount of deformation, when changing the chassis, with regard to the easier fixed underpan of extracting.In addition, because the length direction crosscut of fixed underpan has groove, brake lining mounting plate and fixed underpan easy deformation, even fixed underpan and brake lining mounting plate are because frictional heat deforms, and revising also can be easy, and because the pressure effect of clamp piston, just revised distortion during braking, thereby brake lining is contacted with brake disc under straight state, can prevent the brake lining unbalance stress and produce bad phenomenon such as piece, spot corrosion, prevent that braking force is low.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～4, a kind of bullet train brake lining with fixed underpan, form by fixed underpan 4, friction plate 3-1 and brake lining mounting plate 3-2, friction plate 3-1 is fixed on the brake lining mounting plate 3-2 by rivet 3-3, brake lining mounting plate 3-2 is fixedlyed connected with fixed underpan 4 by rivet 4-1, in the length direction crosscut of fixed underpan 4 groove 6 is arranged.The width of groove 6 is 1/40T～3T with respect to the thickness (T) of fixed underpan 4, the degree of depth of groove 6 relatively and fixed underpan thickness (T) be 1/4T～1T.If the width of groove 6 is littler than 1/40T, then be difficult to revise distortion, the words bigger than 3T can have influence on the distortion of brake lining mounting plate 3-2.The depth ratio 1/4T of groove 6 is little in addition, can be disappeared by the alleviation effects of 6 pairs of amount of deformation of groove.
As shown in Figure 2, groove 6 is positioned at the middle part of fixed underpan 4, near the position of two five equilibriums.
Also can on fixed underpan 4, open many grooves arranged side by side 6.
Shown in Fig. 5,6, braking clamp 1 is to cross over to be installed on the brake disc 2, for being pressed, brake lining is attached on the brake disc 2, fixed underpan 4 is connected slidably with the brake lining support 1-1 of clamp 1, fastening piece 5 is fixed on the two ends of fixed underpan 4, and the recess 4-2 at the protuberance 5-1 of fastening piece 5 and fixed underpan 4 two ends is chimeric.
Working principle of the present utility model is as follows: by fixed underpan 4 brake lining is fixed on the braking clamp 1, the frictional heat that produces during clamp 1 braking and the brake pad that causes and the distortion of fixed underpan 4, the groove 6 of crosscut that is fixed on 4 length directions of chassis is separated, and can reduce whole amount of deformation.Reduced amount of deformation, when changing the chassis, with regard to the easier fixed underpan 4 of extracting.In addition, because the length direction crosscut of fixed underpan 4 has groove 6, brake lining mounting plate 3-2 and fixed underpan 4 easy deformation, even fixed underpan 4 and brake lining mounting plate 3-2 are because frictional heat deforms, and revising also can be easy, and because the pressure effect of clamp piston, just revised distortion during braking, thereby brake lining is contacted with brake disc 2 under straight state, can prevent the brake lining unbalance stress and produce bad phenomenon such as piece, spot corrosion, prevent that braking force is low.
