Background
The disc brake has the advantages of compact structure, high braking efficiency, high braking power and the like, and is used for high-speed trains. As train speeds increase, the demand for train braking also increases.
During the braking process of the train, continuous vertical pressure, tangential friction force, sudden impact force and the like exist on friction surfaces of the brake pads and the brake disc. Under the action of strong friction force, the temperature of the friction surface rises sharply, and a temperature gradient is formed to generate stress, so that the brake pad of the high-speed train is exposed to extremely harsh use conditions, and can fail due to various factors.
The brake pad is an important part of a disc brake and mainly comprises a friction block and a steel backing. The common steel backing is formed by riveting or welding a dovetail plate and a steel backing mounting plate to form the brake pad. However, the brake pad in the form has the risk of rivet or welding seam fracture failure, so that the steel backing mounting plate and the dovetail plate are peeled off, and potential safety hazards are caused to train running.
The operational environment of train brake pad is comparatively abominable, can receive sleet, the influence of sand and dust weather to and consider chip removal and radiating effect, all require to increase the clearance between the clutch blocks as far as possible, if the clutch blocks adopts the structure of stumbling from hindering, can't guarantee the requirement in clearance, and the contact of each other between the clutch blocks, can increase the risk that the clutch blocks drops, but too big clearance can lead to the clutch blocks to take place autogyration in braking process, thereby reduce braking effect.

Preferably, the friction block sequentially comprises a friction block base body top cap, a friction block spring fixing part, a friction block positioning part and a friction block friction part; the friction block base body top cap is cylindrical, the friction block spring fixing portion is cylindrical, the upper portion of the friction block positioning portion is cylindrical, the lower portion of the friction block positioning portion is circular truncated cone-shaped, the friction portion of the friction block is cuboid-shaped, and four vertical edges of the friction block base body top cap are fillets.
Preferably, the friction block penetrates through the disc spring through the friction block positioning part and penetrates through the mounting hole of the steel back mounting plate; the spring is arranged on the friction block spring fixing part, and the friction block is fixed through spring force applied to the friction block base body top cap by the spring.
Preferably, one side of the steel back is respectively provided with two strip-shaped blocking bosses.
Preferably, a gap of 1-2mm is reserved between the blocking lug boss and the friction block.
Since the technical scheme is used, the utility model discloses the outstanding technological effect who gains does:
the utility model discloses a dovetail platform and steel backing mounting panel are integrated into one piece's form, have improved the structural strength of train brake pad steel backing mounting panel.
The utility model discloses a boss is stumbled to design area type on the steel backing, has restricted the autogyration of clutch blocks, has improved the frictional behavior.
