Abstract

The utility model provides a novel dovetail-structured synthetic brake pad which is characterized by including a brake pad steel back and a brake pad friction body. The brake steel pad is a sheet steel stamping workpiece with a dovetail structure, a groove is arranged in the middle of the dovetail structure, and the wide end and the narrow end are in an asymmetrical structure, wherein the wide end is arranged at the outer side of the brake pad and the narrow end is arranged at the inner side of the narrow end. The brake pad provided not only realizes the heat radiation, but also increases the connection strength between the brake pad friction body and a brake pad back plate; meanwhile, the uniform load during the braking can be realized and the brake pad can be prevented from rotating with respect to the center of the dovetail structure in a brake pad holder. Because the brake pad friction body is made of synthetic materials and grooves in cross connection are arranged in the friction surface of the brake pad friction body, the discharging of grinding powder is facilitated, the deformation of the friction body after thermal expansion can be prevented, good contact between the friction body and a friction ring is realized, the braking performance is improved, and the service lifetime of the brake pad is prolonged. The brake pad provided is simple in connection, good in braking performance, safe and reliable in application, and can be widely applied to a disc-shaped braking device of a vehicle braking system.

Description

A kind of novel dovetail structure is synthesized brake lining
Technical field
The utility model relates to a kind of disc brake that is applied to railway vehicle, particularly connects the synthetic brake lining of steel backing structure about a kind of novel dovetail.
Background technique
Application and the development in bogie of car brake rigging along with reel and disc brake also obtained extensive use and development as the critical component brake pad of disc brake.For the standard brake pad make UIC541-3 and TB/T3118 clearly stipulated the synthetic brake lining of vehicle specification and with the Placement of brake clip clamp device, satisfied the car brakeing requirement.
Although the synthetic brake pad of existing structure form can satisfy the use of disc brake substantially, but along with the change of vehicle operating pattern and the raising of speed class, brake lining high temperature abrasion are serious, friction factor is unstable, it is more and more outstanding easily to hinder defective such as brake disc.In order to adapt to the car operation requirement, to the heat dispersion of synthetic brake lining, all carry, have higher requirement working life.
Therefore, the design of optimizing structure provides the synthetic brake pad that satisfies vehicle braking performances requirement and general installation requirement just very necessary.
The model utility content
Based on above-mentioned technical background, the purpose of this utility model is: pass through structural design, efficiently radiates heat when realizing braking, reduce the heat load of brake lining, satisfying on the general dovetail structure connection basis, brake lining contacts inequality or deflection when avoiding braking with brake disc, provides a kind of and can satisfy and improve the train braking performance, guarantees a kind of novel brake pad of security of operation.
For achieving the above object, the utility model by the following technical solutions: a kind of novel dovetail structure is synthesized brake lining, and it is characterized in that: it comprises brake lining steel backing, brake lining friction piece;
Described brake lining steel backing is the die mould spare that has the dovetail structure, is stamped to form by sheet metal, is provided with a groove, asymmetric arrangement at the dovetail middle part;
Described brake lining friction piece is made by composite, and brake lining friction piece rubbing surface is provided with cross-coupled groove, with the brake lining steel backing by cold-rolled sintered be one.
The utility model is owing to take above technological scheme, it has the following advantages: 1, the utility model brake lining steel backing is on the basis of general dovetail structure, be provided with a groove at the dovetail middle part, non-symmetry structure, not only realize heat radiation but also can increase the join strength of brake lining friction piece and brake lining backboard, all carry in the time of also can realizing braking simultaneously, avoid brake lining in brake plate support, to rotate relative to the dovetail center.2, the utility model brake lining friction piece rubbing surface is provided with cross-coupled groove, be conducive to discharge powder after the abrasion, avoid the distortion of brake lining friction piece after the thermal expansion, realize that the brake lining friction piece well contacts with friction ring, improve braking ability, increase brake lining working life.
The utility model connects simple, and braking ability is good, and application safety is reliable, can be widely used in the disc brake of vehicle braked system.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
Shown in Fig. 1~3, the utility model mainly comprises brake lining steel backing 1, brake lining friction piece 2.
Shown in Fig. 1~3, described brake lining friction piece of the present utility model 2 is made by composite, brake lining friction piece rubbing surface 21 is provided with cross-coupled spill tangential slot 22 and spill radial groove 23, be conducive to discharge powder after the abrasion, avoid the distortion of brake lining friction piece after the thermal expansion, thereby make brake lining and brake disc in the work have the excellent contact area.
Shown in Fig. 4~5, brake lining steel backing 1 of the present utility model adopts sheet metal to be stamped to form, have dovetail structure 11, be provided with a groove 12 at the dovetail middle part, pass to the heat on the brake lining when not only being conducive to distribute braking, and the increase of area of contact is conducive to being connected of brake lining friction piece and backboard, the narrow end 13 of dovetail steel backing of non-symmetry structure is arranged in the brake lining inboard simultaneously, wide end 14 is arranged in the brake lining outside, can avoid brake lining in brake plate support, to rotate relative to the dovetail center, all carry when realizing braking.
The main brake lining steel backing 1 of the utility model and brake lining friction piece 2 are by the cold-rolled sintered brake lining that is formed as one.
After the utility model manufacturing is finished, along the dovetail 11 of brake lining steel backing 1 from insert the dovetail groove on the braking clamp down, then by the positioning device on the braking clamp with brake lining steel backing 1 with brake clamp and fix.In braking device when work,, retardation pressure acts on the brake lining steel backing 1, is delivered on the brake lining friction block 2 by steel backing 1, and the brake disc of steadily fitting is implemented braking.
The various embodiments described above only are used for explanation the utility model; wherein the structure of each parts, Placement etc. all can change to some extent; every equivalents and improvement of carrying out on the basis of technical solutions of the utility model all should do not got rid of outside protection domain of the present utility model.
