Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to an installation structure of a brake disc for a locomotive. Background Art

[0002] The installation structure of a locomotive brake disc specifically refers to the connection method between the brake disc and the locomotive wheel. Currently, in China, the wheel-mounted brake discs of locomotives generally adopt a connection method of bolts cooperating with lock nuts and supplemented by positioning pins for fixation. However, this design has a significant problem: the positioning pins and the wheels adopt a clearance fit, which often leads to uneven distribution of forces on the positioning pins, and they are prone to being sheared one by one due to stress concentration, thus affecting the stability and safety of the entire connection structure. In response to the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Content of the Utility Model

[0003] To achieve the above objectives, the utility model is realized through the following technical solutions: an installation structure of a brake disc for a locomotive, comprising: a wheel, a pair of convex ring brake discs, and a quick installation structure. The pair of convex ring brake discs are installed on the wheel through the quick installation structure. The quick installation structure includes: several convex telescopic cylindrical blocks, several telescopic support balls, several adsorption metals, a disassembly ring adsorption magnet, several fixing bolts, several elastic gaskets, and several fixing nuts;

[0004] A pair of ring grooves are opened on the wheel, and the pair of convex ring brake discs are respectively movably inserted into the inner sides of the pair of ring grooves. A pair of ring disassembly grooves are respectively opened on the pair of convex ring brake discs. Several convex cylindrical holes and several are respectively opened on the pair of ring disassembly grooves. Disassembly and assembly holes are respectively opened on the pair of ring disassembly grooves and the pair of ring grooves. Several fixing bolts are respectively movably inserted into the several disassembly and assembly holes. Several elastic gaskets are respectively sleeved in pairs on the several fixing bolts. Several fixing nuts are respectively installed on the several fixing bolts. Several convex telescopic cylindrical blocks are respectively movably inserted into the inner sides of the several convex cylindrical holes. Several telescopic support balls are respectively movably inserted on the several convex telescopic cylindrical blocks. Several adsorption magnets are respectively installed on the several convex telescopic cylindrical blocks. The disassembly ring adsorption magnet is respectively movably inserted into the inner sides of the pair of ring grooves. Several adsorption metals are respectively installed on the several discharge holes;

[0005] It should be noted that in the above, by movably inserting a pair of convex ring brake discs into the inner side of the ring grooves on the wheel, with the rotation of the wheel, they rotate centrifugally, driving a number of convex telescopic cylindrical blocks on the convex ring brake discs to be centrifugally inserted into the convex cylindrical holes due to centrifugal rotation. When the wheel stops, due to gravity, the convex telescopic cylindrical blocks are inserted into the inner side of the convex cylindrical holes, so as to carry out extended support in the vertical direction. At the same time, the convex ring brake discs are limited on the wheel through fixing bolts, spring washers and fixing nuts. At the same time, a number of telescopic support balls buffer the bumps during centrifugation. At the same time, the convex telescopic cylindrical blocks are magnetically adsorbed through the dismounting ring adsorption magnets, so that the convex ring brake discs can be quickly disassembled.

[0006] Preferably, a number of centrifugal holes are respectively formed in a pair of the ring grooves.

[0007] Preferably, ring covers are respectively arranged on the inner sides of a pair of the ring dismounting grooves.

[0008] Preferably, cover grooves are formed in a pair of the ring dismounting grooves, and toothed openings are respectively formed in a pair of the cover grooves.

[0009] Preferably, a number of toothed insertion blocks are arranged on a pair of the ring covers.

[0010] Preferably, a number of the toothed insertion blocks are movably inserted into the inner sides of a pair of the toothed openings.

[0011] The utility model provides a mounting structure for a braking disc of a locomotive, which has the following beneficial effects. Compared with the prior art, this mounting structure for a braking disc of a locomotive realizes the quick and stable installation of the convex ring braking disc through the cooperation of the convex telescopic cylindrical block and the convex cylindrical hole, as well as the fastening action of the fixing bolt, the elastic gasket and the fixing nut. When disassembly is required, only by using the disassembly ring adsorption magnet to magnetically adsorb the convex telescopic cylindrical block, the convex ring braking disc can be easily removed from the wheel, greatly improving the work efficiency. When the wheel rotates, the convex telescopic cylindrical block automatically extends outwards due to the centrifugal force and inserts into the convex cylindrical hole, enhancing the stability of the braking disc in the rotating state. When the wheel stops, the convex telescopic cylindrical block remains inserted under the action of gravity, providing additional support for the braking disc in the vertical direction and further improving the firmness of the installation. The arrangement of several telescopic support balls effectively buffers the bumps and vibrations that may occur during the rotation of the wheel, protecting the convex ring braking disc and the wheel from damage. In addition to the limiting effect of the convex telescopic cylindrical block, the combination of the fixing bolt, the elastic gasket and the fixing nut also provides an additional limiting effect, ensuring the stability of the convex ring braking disc on the wheel and enhancing the driving safety. Due to the adoption of the quick installation structure, when the convex ring braking disc needs to be maintained or replaced, it can be quickly disassembled and installed, reducing the maintenance cost and time. The design of the ring cover and the toothed insertion block is not only beautiful but also practical, effectively preventing sundries from entering the ring disassembly groove and providing convenience for disassembly.
