Furthermore, since the first conductive elastic element 110 has good elasticity, after the problem of discharge due to potential difference is solved, the first conductive elastic element 110 is compressed under the control of the braking system so that the brake pad friction body 102 contacts with the rail, and then the magnetic levitation train is braked by friction.

In order to ensure that the conductive block 112 always contacts the rail before the brake pad friction body 102, a certain pre-tightening force can be applied to the sub-conductive elastic body 111. The conductive block 112 can increase the contact area with the rail, thereby facilitating rapid elimination of the potential difference, increasing the friction force and realizing rapid braking.

The carbon plate support frame 113 is a support fixing element of the carbon sliding plate 115, and mainly bears longitudinal pressure and shearing force when the maglev train brakes, so that plates with high temperature resistance, corrosion resistance and excellent mechanical properties, such as 316L and 310S, are selected in the embodiment.
In order to enhance the connection strength between the carbon plate support frame 113 and the carbon sliding plate 115, the carbon plate support frame 113 and the carbon sliding plate 115 are bonded together by adhesive, and the main component of the adhesive is polyurethane or the like. Due to the influence of the insulating property of the adhesive, in order to maintain good conductivity between the carbon plate support frame 113 and the carbon slide plate 115, a metal mesh 114 is arranged between the carbon plate support frame 113 and the carbon slide plate 115 to ensure that charges carried by the maglev train can be transferred to the ground without hindrance.

The embodiment provides a brake pad 200 for braking a second train, which comprises a brake pad body and a second conductive elastic element 120, wherein the brake pad body comprises a brake pad back plate 101 and a brake pad friction body 102, and the brake pad back plate 101 and the brake pad friction body 102 are connected or integrally formed; the second conductive elastic element 120 and the brake pad friction body 102 are disposed on the same side of the brake pad backing plate 101, the brake pad friction body 102 has a first surface and a second surface disposed oppositely, the first surface is connected to the brake pad backing plate 101, and one end of the second conductive elastic element 120 away from the brake pad backing plate 101 is higher than the second surface. The longitudinal height (from top to bottom in fig. 2) of the second conductive elastic member 120 is greater than the longitudinal height of the brake pad friction body 102, the second conductive elastic member 120 contacts with the rail before the brake pad friction body 102 in the braking process, the rail is connected with the sleeper, and the sleeper is connected with the ground, so that the potential difference generated after the maglev train contacts with the rail is eliminated, damage such as electric corrosion is prevented, the safety performance of the maglev train braking can be improved, and the service life of the brake pad can be prolonged. In the braking process of the maglev train, the brake pad generates a large amount of heat due to the friction effect and is exposed to the external environment for a long time, so the second conductive elastic element 120 should have good conductivity, toughness, high temperature resistance, corrosion resistance and oxidation resistance, and the second conductive elastic element 120 of the embodiment is made of a GH169 material.
Further, a first sinking groove 103 is formed on the brake pad back plate 101; the connection point of the second conductive elastic element 120 and the brake pad back plate 101 is disposed in the first sinking groove 103. The first sinking groove 103 can limit the displacement of the second conductive elastic member 120 on the brake pad backing plate 101. Especially, when the second conductive elastic member 120 is connected to the brake pad back plate 101 by 1 bolt or rivet, the first sinking groove 103 may fix the connecting member to some extent.
