The steel backs in the brake pads all adopt solid structures, the friction bodies are fastened and strongly supported in the braking process, and the friction bodies are severely supported, so that the friction bodies and the brake disc are severely rubbed during braking and braking along with the change of the vehicle running mode and the improvement of the speed grade, and higher requirements are also brought to the supporting strength of the steel backs. The traditional steel backing is a strip-shaped steel plate with a groove, a plurality of square process holes similar to window shapes are formed in the base plate portion of the steel plate, inward-turned edges are pressed at the process holes and can be tightly combined with friction bodies combined in a pressing mode through the groove, the process holes and the inward-turned edges, the steel backing is weakened in strength of bearing external force, poor in stability and low in safety, the steel backing is easy to bend, distort and even damage under the action of bearing huge vibration and pressure, and the brake pad loses the braking effect.
Disclosure of Invention
The utility model aims at providing a synthetic brake lining strenghthened type steel backing has solved the poor stability that traditional synthetic brake lining steel backing and frictional body combine, and intensity is not enough, the problem of yielding damage, and it is not flexible to damage, simple structure can stably combine with the frictional body.
The utility model adopts the technical proposal that: this synthetic brake lining strenghthened type steel backing includes: set up the notched steel sheet at middle part length direction, the recess lateral wall is provided with the side edge of turning up, and its technical essential is: the cross section of the groove is in a dovetail shape with an outer opening gradually widened towards the bottom, a plurality of cross beams are transversely welded at the bottom of the groove, the cross beams abut against the inner side wall of the groove by utilizing oblique end faces at two ends, symmetrical fins are integrally arranged at two sides of the middle part of each cross beam, and circular exhaust holes are formed in steel plate parts corresponding to the cross of the cross beams and the fins; and a gap is reserved between the bottom angle end of the oblique end surface of the cross beam of the steel plate and the corresponding bottom angle of the groove.
One end of the steel plate in the length direction is a front end with an oblique angle.
The utility model has the advantages and positive effects that: because the cross beam is arranged in the groove with the dovetail-shaped cross section of the reinforced steel back of the synthetic brake pad, and the fins are symmetrically arranged on two sides of the middle part of the cross beam, the strength of the steel back is greatly increased, the steel back can be effectively prevented from deforming in the pressing process of the brake pad, the steel back is welded and fixed with the cross beam at the bottom of the groove, the structural rigidity and the structural integrity are improved, meanwhile, the welding, the fixing and the connection are convenient, the self strength is improved, and the flatness of the installation surface is ensured; round exhaust holes are formed in the steel plate portion corresponding to the cross beam and the fins in a crossed mode, gaps are reserved between bottom corner ends of the oblique end faces of the cross beam of the steel plate and corresponding bottom corners of the grooves, and the situation that the cross beam and the fins form dead corners to exhaust hot-pressing gas difficultly is avoided. When braking load, the brake pad can avoid torsional deformation caused by insufficient rigidity of the brake pad, and the service life of the brake pad is prolonged; the cross beam, the fins and the grooves are constructed to form a convex-concave shape, and can be tightly combined with the friction body. The structure is simple, the pressing is convenient, and the production efficiency is effectively improved; the brake pad product formed by pressing the steel backing and the friction body has good braking performance, can adopt the combination of the longer steel backing and the friction body, is firm and durable, runs safely and reliably, and can be widely applied to a disc type braking device of a railway locomotive braking system.
