Abstract
The utility model discloses a high-speed brake lining with an elastic structure, which comprises a steel backing (1), a brake block (2), a dovetail plate (3), a gasket (4), a disk spring (5), a guiding sleeve (6), a lining (7) and a rivet (8). The high-speed brake lining with the elastic structure has the advantages of good mechanical strength, little abrasion loss, stable friction performance, good heat stability, good heat conductivity, large kinetic moment and static moment, no noise, excellent seawater corrosion resistance, excellent sandstorm preventing property, excellent salt mist resistance and the like. As the elastic structure is adopted, eccentric wear of the brake block of the high-speed lining caused by non-full contact between the brake block of the high-speed lining and the surface of a brake disc can be avoided, and further a high-speed train is led to brake steadily with a short braking distance.
Description
Technical field
The utility model relates to the high speed train brake gear, particularly relates to a kind of elastic construction high speed brake lining.
Background technology
High-revolving train braking is to rely on high speed brake lining friction brake disk to realize, existing high speed brake lining adopts welding or riveted structure more, the brake shoes of ubiquity high speed brake lining contacts insufficient with the brake disc surface and causes the brake shoes eccentric wear phenomenon of high speed brake lining outstanding, and the friction shoe periphery easily produces the limit arrisdefect, abrasion loss is big, thereby cause high-speed train braking steady inadequately, stopping distance is long.
Summary of the invention
The technical matters that solves
For addressing the above problem, the utility model provides a kind of elastic construction high speed brake lining.
Technical scheme
The disclosed elastic construction high speed of the utility model brake lining is achieved in that elastic construction high speed brake lining, is made up of steel backing 1, brake shoes 2, coattail board 3, packing ring 4, disk spring 5, orienting sleeve 6, lining 7, rivet 8.Finish and after the agglomerant of brake shoes 2 does to finish in each part processing, at first carry out the riveting work of each part, be specially: rivet 8 is passed rivet hole on the steel backing 1, then a packing ring 4 is enclosed within on the rivet 8, again orienting sleeve 6 is installed between rivet 8 and two disk springs 5, two disk springs 5 mode dos-as shown in Figure 3 is enclosed within outside the orienting sleeve 6, be inserted in another part packing ring 4 then, again brake shoes 2 is inserted in rivet 8 by its rivet hole, at last lining 7 is enclosed within rivet 8 outsides, orienting sleeve 6 inboards.
The effect one of described lining 7 is in order to guarantee when retrothrust is big; shearing force directly acts on lining 7; can protect rivet 8 not to be damaged; the 2nd, the deflection of the distance disk spring when utilizing the part length of lining 7 to control riveted joint between brake shoes 2 and the steel backing 1; the 3rd, after the lining 7 end-face hole chamferings; rivet 8 its dies of riveted joint back are difficult for being pulled the reliability height.Described lagging material is selected the material that the back distortion of high heat is little, hardness is high for use, such as 30CrMnSi.
Described disk spring 5 is subjected to can produce distortion behind the application force, utilize this characteristic, after elastic construction high speed brake lining described in the utility model is subjected to the retrothrust effect, the angle of brake shoes 2 can change, the friction face of brake shoes 2 can fully contact brake disc, thereby realizes alleviating and even avoiding the purpose of brake shoes 2 eccentric wears.
Because disk spring 5 hardness are higher, along with disk spring work increased frequency, the skeleton 9 and disk spring 5 contact surfaces of steel backing 1 and brake shoes 2 can occur uneven, influence the deflection of disk spring 5.Therefore adopt packing ring 4 to avoid the wearing and tearing and the distortion of steel backing 1 and skeleton 9, this packing ring 4 should be selected high heat back hardness and the cooresponding material of disk spring 5 hardness for use, as 65Mn.
Beneficial effect
Advantages such as the elastic construction high speed brake lining that the utility model provides has that mechanical strength is good, abrasion loss is little, stable friction performance, Heat stability is good, good heat conductivity, kinetic moment and statical moment height, noiselessness, anti-marine corrosion, anti-dust storm, anti-salt fog function admirable.And owing to adopt elastic construction, avoided the brake shoes of high speed brake lining to contact insufficient with the brake disc surface and cause the brake shoes eccentric wear phenomenon of high speed brake lining, made high-speed train braking steady, stopping distance is lacked.
Description of drawings
Fig. 1 is the planar view of the utility model elastic construction high speed brake lining.
Fig. 2 is the A-A cutaway view of the utility model elastic construction high speed brake lining.
Fig. 3 is the amplification view of the elastic construction part of the utility model elastic construction high speed brake lining.
The specific embodiment
In conjunction with the accompanying drawings, the disclosed elastic construction high speed of the utility model brake lining is made up of steel backing 1, brake shoes 2, coattail board 3, packing ring 4, disk spring 5, orienting sleeve 6, lining 7, rivet 8.Finish and after the agglomerant of brake shoes 2 does to finish in each part processing, at first carry out the riveting work of each part, be specially: rivet 8 is passed rivet hole on the steel backing 1, then a packing ring 4 is enclosed within on the rivet 8, again orienting sleeve 6 is installed between rivet 8 and two disk springs 5, two disk springs 5 mode dos-as shown in Figure 3 is enclosed within outside the orienting sleeve 6, be inserted in another part packing ring 4 then, again brake shoes 2 is inserted in rivet 8 by its rivet hole, at last lining 7 is enclosed within rivet 8 outside orienting sleeves 6 inboards.
The effect one of described lining 7 is in order to guarantee when retrothrust is big; shearing force directly acts on lining 7; can protect rivet 8 not to be damaged; the 2nd, the deflection of the distance disk spring when utilizing the part length of lining 7 to control riveted joint between brake shoes 2 and the steel backing 1; the 3rd, after the lining 7 end-face hole chamferings; rivet 8 its dies of riveted joint back are difficult for being pulled the reliability height.Described lagging material is selected the material that the back distortion of high heat is little, hardness is high for use, such as 30CrMnSi.
Described disk spring 5 is subjected to can produce distortion behind the application force, utilize this characteristic, after elastic construction high speed brake lining described in the utility model is subjected to the retrothrust effect, the angle of brake shoes 2 can change, the friction face of brake shoes 2 can fully contact brake disc, thereby realizes alleviating and even avoiding the purpose of brake shoes 2 eccentric wears.
Because disk spring 5 hardness are higher, along with disk spring work increased frequency, the skeleton 9 and disk spring 5 contact surfaces of steel backing 1 and brake shoes 2 can occur uneven, influence the deflection of disk spring 5.Therefore adopt packing ring 4 to avoid the wearing and tearing and the distortion of steel backing 1 and skeleton 9, this packing ring 4 is answered high heat back hardness and the cooresponding material of disk spring 5 hardness, as 65Mn.
