Abstract

The invention discloses a high-speed train and rail transit vehicle brake pad, and relates to the high-speed train and rail transit vehicle braking technology. According to the structure of the high-speed train and rail transit vehicle brake pad, a friction block center through hole is machined in the center of a friction block, the friction block and a lining plate are welded or sintered in a pressurized mode into a whole, a plurality of concentric through holes on different-radius arcs are machined in a steel base plate, and through holes in the same specification as the through holes in the steel base plate are machined in the lining plate; inserting pins and springs are installed in the through holes of the steel base plate; pin holes are machined in one sides of fastening nails; the fastening nails penetrate through the friction block center through hole and the through holes of the lining plate and the steel base plate so that the inserting pins can be fixed into the pin holes; the friction block is in the shape of an oval, an isosceles trapezoid, a triangle with three angles cut off, a bike saddle and the like. The high-speed train and rail transit vehicle brake pad has the advantages of being novel in structure, easy and convenient to machine, convenient and fast to install and detach, efficient in heat dissipation, safe, reliable and the like, and therefore the high-speed train and rail transit vehicle brake pad is both economical and practical.

Description

technical field [0001] The brake pads for high-speed trains and rail transit vehicles of the present invention relate to a braking technology for high-speed trains and rail transit vehicles. Background technique [0002] At present, the speed of high-speed trains and rail transit vehicles is getting faster and faster, and the requirements for the safety and reliability of their brake pads are getting higher and higher. In the existing and disclosed related technologies, the friction block adopts processes such as welding and riveting, which make it troublesome to replace the friction block. In addition, the shapes of these friction blocks are unreasonable, which may easily cause damage to the friction blocks and uneven heat dissipation. For the problems existing in the above-mentioned prior art, it is very necessary to study and design a novel brake pad for high-speed trains and rail vehicles, thereby overcoming the problems existing in the prior art. Contents of the inve...
