Description
Technical Field
The utility model relates to a braking system technical field, concretely relates to green skin train brake block steel backing.
Background
In a braking system, a brake pad is the most critical safety part, and the quality of all braking effects plays a decisive role. In the using process, the brake pad is in contact friction with the brake disc or the brake drum, so that the effect of deceleration and braking of the vehicle is achieved. At present, the existing brake pad generally comprises a steel backing and a friction block, and a large shearing force is generated when the friction block is in friction with a brake disc in the use process, so that the relative stability between the steel backing and the friction block is enhanced, the situation that the friction block is separated from the steel backing is avoided, in the preparation process, a dovetail block or a steel mesh is welded on the steel backing preferentially, and then the friction plate is bonded on the dovetail block or the steel mesh.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above-mentioned problem, provide a structural design is reasonable, with the green skin train brake block steel backing that friction disc bonding stability is good.
The utility model adopts the following technical scheme:
the utility model provides a green skin train brake block steel backing, includes steel backing body and a plurality of group evenly distributed's the mechanism that rubs that increases on the steel backing body, the steel backing body includes that the steel backing openly with the steel backing back, increase the mechanism that rubs including set up increase on the steel backing openly groove, set up on the steel backing back and with increase the radiating groove that the groove corresponds the setting and a plurality of along the increase hole that rubs on the steel backing body of circumferential direction evenly distributed in groove that rubs, increase through the connecting hole intercommunication between groove and the radiating groove, increase the inslot evenly distributed that rubs and have a plurality of to increase the piece that rubs, it is arrow point shaped structure to increase the piece that rubs.
As a preferred technical scheme of the utility model, it has a plurality of amortization louvre to go back evenly distributed on the steel backing body, the one end that is close to the steel backing back on the amortization louvre is the loudspeaker column structure of outside expansion.
As an optimized technical scheme of the utility model, every increase the quantity that the circumference direction of groove corresponds that rubs the hole and be more than two.
As an optimized technical scheme of the utility model, the area of radiating groove is greater than the area that increases the friction groove.
The utility model has the advantages that:
the utility model has reasonable structural design, wherein the friction increasing groove and the friction increasing hole which are arranged on the friction increasing mechanism can increase the contact area when the steel back body is bonded with the friction plate, and the friction increasing piece which is arranged in the friction increasing groove adopts an arrow-shaped structural arrangement, and the friction plate can be clamped on the steel back body by adopting the structural arrangement so as to further enhance the connection stability between the steel back body and the friction plate;
2. the utility model discloses the heat dispersion of improvement brake block that the radiating groove that sets up can be great when using, the one end that sets up simultaneously is the thermal diffusivity of improvement brake block when using that the amortization louvre of the loudspeaker form of outside expansion not only can be further, can also strengthen the amortization performance of steel backing body.

Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a steel backing of a green-skin train brake pad comprises a steel backing body 1 and a plurality of groups of friction increasing mechanisms uniformly distributed on the steel backing body 1, wherein the steel backing body 1 comprises a steel backing front surface and a steel backing back surface, and in the embodiment, when the steel backing is used, an external friction plate is bonded on the steel backing front surface in a hot melting mode; in the embodiment, the number of the friction increasing mechanisms is five, and in the application process of the embodiment, the number of the friction increasing mechanisms is not limited to five, and a person skilled in the art can determine the number of the friction increasing mechanisms according to actual needs; the friction increasing mechanism comprises a friction increasing groove 2 arranged on the front side of the steel back, a heat radiating groove 3 arranged on the back side of the steel back and corresponding to the friction increasing groove 2, and a plurality of friction increasing holes 4 uniformly distributed on the steel back body 1 along the circumferential direction of the friction increasing groove 2, the friction increasing groove 2 and the heat radiating groove 3 are communicated through a connecting hole 5, a plurality of friction increasing pieces 6 are uniformly distributed in the friction increasing groove 2, and the friction increasing pieces 6 are arrow-head-shaped structures; in the present embodiment, the area of the heat dissipation groove 3 is larger than that of the friction increasing groove 2; the number of the friction increasing holes 4 corresponding to the circumferential direction of each friction increasing groove 2 is more than two, specifically in the embodiment, the number of the friction increasing holes 4 corresponding to the circumferential direction of each friction increasing groove 2 is three;
further, still evenly distributed has a plurality of amortization louvre 7 on the steel backing body 1, the one end that is close to the steel backing back on the amortization louvre 7 is outside expanded loudspeaker column structure.
Finally, it should be noted that: these embodiments are merely illustrative of the present invention and do not limit the scope of the invention. In addition, other variations and modifications will be apparent to persons skilled in the art based on the foregoing description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications may be made without departing from the scope of the present invention.
