Abstract
The utility model provides a novel braking sheet in an elastic structure, which is composed of a steel backing, a braking block, a disk spring, a dovetail plate, a rivet and a bushing. With stable friction performance and good heat conducting property, the processed and manufactured braking sheet not only can effectively brake heavy-load transportation tools and engineering equipment under high temperature, high speed as well as high pressure, but also can solve the problems that the braking friction performance of the braking sheet is instable and a friction body of the braking sheet is abraded in the braking process due to that a braking disc becomes concave-convex after being used for a long time and the radial braking power of the braking disc is inconsistent.
Description
Technical field
The utility model relates to the rail vehicle braking device, particularly relates to a kind of elasticity riveted structure brake block.
Background technique
High-speed train braking is to rely on the brake block friction brake disk to realize, the brake block of existing bullet train adopts welding or riveted structure more, because the linear from inside to outside increase of brake disc radial line speed, cause braking force inconsistent, it is big to cause the instability of braking quality and friction piece Internal and external cycle thickness difference to occur, i.e. eccentric wear phenomenon, and the brake block of ubiquity brake block contacts inadequate phenomenon with the brake disc surface, thereby cause high-speed train braking steady inadequately, stopping distance is long.
Summary of the invention
The technical problem that solves
For addressing the above problem, the utility model provides a kind of elasticity riveted structure brake block, can effectively solve the eccentric wear situation of brake block, the brake block that can fully guarantee brake block fully contacts with the brake disc surface and rub, thereby effectively brakes bullet train.
Technological scheme
The technological scheme that its technical problem that solves the utility model adopts is: elasticity riveted structure brake block is made up of steel backing 1, brake block 2, disk spring 3, coattail board 4, rivet 5, lining 6.Utilize 3 rivets 5 to be riveted on the steel backing 1 each brake block 2, for avoiding the excessive wear of rivet 5, the outside that lining 6 is enclosed within rivet 5 is protected rivet.The effect of disk spring 3 is that elastic strain takes place when being under pressure, thereby realizes the purpose that brake block 2 and train braking panel surface fully contact and rub.During riveted joint, mode as shown in Figure 1 utilizes three rivets 5 disk spring 3 to be fixed in the gap of leaving between steel backing 1 and the brake block 2, for giving full play to the effect of disk spring 3, leave certain distance to guarantee the deformation space of disk spring 3 between three rivets 5 and the disk spring 3.Having dug the arc fixed groove in the position that steel backing 1 and disk spring 3 peaks are tangent, is that stretch towards periphery in the center of circle with this arc fixed groove when guaranteeing that disk spring 3 being under pressure elastic strain takes place.
Be the abundant fixedly position of disk spring 3, as shown in Figure 5 mode around the disk spring 3 has been dug fixed groove, mode as shown in Figure 1 is riveted in three rivets, the 5 formed fixed spaces, for giving full play to the effect of disk spring 3, leave certain distance to guarantee the deformation space of disk spring 3 between three rivets 5 and the disk spring 3.
Beneficial effect
The novel elastic structure brake block that the utility model provides because disk spring 3 has been installed, can effectively solve the eccentric wear situation of brake block, brake block and the brake disc that can fully guarantee brake block surperficially fully contacts and rub, thereby effectively brake bullet train.

Embodiment
Novel elastic structure brake block steel back 1, brake block 2, disk spring 3, coattail board 4, rivet 5, lining 6 are formed.Utilize 3 rivets 5 to be riveted on the steel backing 1 each brake block 2, for avoiding the excessive wear of rivet 5, the outside that lining 6 is enclosed within rivet 5 is protected rivet.The effect of disk spring 3 is that elastic strain takes place when being under pressure, thereby realizes the purpose that brake block 2 and train braking panel surface fully contact and rub.During riveted joint, mode as shown in Figure 1 utilizes three rivets 5 disk spring 3 to be fixed in the gap of leaving between steel backing 1 and the brake block 2, for giving full play to the effect of disk spring 3, leave certain distance to guarantee the deformation space of disk spring 3 between three rivets 5 and the disk spring 3.Having dug the arc fixed groove in the position that steel backing 1 and disk spring 3 peaks are tangent, is that stretch towards periphery in the center of circle with this arc fixed groove when guaranteeing that disk spring 3 being under pressure elastic strain takes place.
Be the abundant fixedly position of disk spring 3, as shown in Figure 5 mode around the disk spring 3 has been dug fixed groove, mode as shown in Figure 1 is riveted in three rivets, the 5 formed fixed spaces, for giving full play to the effect of disk spring 3, leave certain distance to guarantee the deformation space of disk spring 3 between three rivets 5 and the disk spring 3.Coattail board 4 is welded on the opposite side of steel backing 1, and effect is novel elastic structure brake block of the present utility model is fixed on the mounting point of train.
