Detailed Description
In the following, the technical solutions in the embodiments of the present invention are described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.
The utility model discloses specific embodiment adopts following technical scheme: as shown in fig. 1 and 2, a brake pad steel backing convenient for friction material fixing comprises a steel backing body 1, a plurality of grooves 11 are arranged on the surface of the steel backing body 1 at intervals, the size of the bottom end of each groove 11 far away from the surface of the steel backing is larger than that of the top end, the cross section of the expansion mechanism can be in a conical shape or other structures, the bottom end of the groove 11 is provided with the expansion mechanism 2, the expansion mechanism 2 can ensure that the groove 11 can not fall off after the expansion mechanism 2 expands due to the structure that the upper part of the groove 11 is narrow and the lower part of the groove is wide, the expansion mechanism 2 comprises an air bag 21 and a heat conducting rod 22, one end of the heat conducting rod 22 extends into the air bag 21 and is fixedly connected with the air bag 22, the connection part is the air outlet of the air bag 21, the other end is positioned in the friction material 3 and is fixedly connected with the friction material 3, the friction material 3 and the air bag 21 are connected to form an integral structure through the heat conducting rod 22, and a heat conducting channel is established, and the heat conducting rod 22 is made of a copper rod with good heat conductivity.
As shown in fig. 3, the groove channel direction of the groove 11 is preferably perpendicular to the track plane formed by the rotation direction of the vehicle wheel, so that the friction material 3 cannot be separated along the groove channel direction of the groove 11 under the action of the radial component force of the rotation of the wheel when the brake pad steel back works.
As shown in fig. 2, preferably, the heat insulation film 4 is sleeved at the joint of the heat conduction rod 22 and the air bag 21, and the arrangement of the heat insulation film 4 can avoid the direct contact between the air bag 21 and the heat conduction rod 22, prevent the air bag 21 from being damaged by high temperature, ensure the air tightness of the air outlet of the air bag 21, and prevent heat loss.
As shown in fig. 2, preferably, the outer surface of the air bag 21 is provided with irregular protrusions and recesses 211, and the protrusions and recesses 211 can increase the friction force between the outer wall of the air bag 21 and the inner wall of the bottom end of the groove 11, so that when the active brake pad is used, the air bag 21 slides out of the groove 11, thereby preventing the friction material 3 from falling off.
As shown in fig. 1, preferably, the surface of the steel back body 1 is coated with the colloid 5, the colloid 5 is located between the friction material 3 and the steel back body 1, and the shearing force between the friction material 3 and the steel back body 1 can be further enhanced through the viscosity of the colloid 5, so that the friction material 3 is prevented from falling off.
