Abstract

The invention belongs to the technical field of train braking, and particularly relates to an externally-wrapped friction block for a high-speed train brake. The externally-wrapped friction block forthe high-speed train brake comprises a friction block steel back bottom plate, friction block steel back arc claws, a friction block compact blank, first through holes and second through holes. The friction block adopts the externally-wrapped structure, the friction block compact blank is buckled tightly, the firmer effect is realized, the shear resistance and the shock resistance between a friction block steel back and a bonding surface of a friction material layer are enhanced, the phenomena of falling and chipping of the friction material layer can be avoided, and thus a brake pad works more safely and reliably.

Description

technical field [0001] The invention belongs to the technical field of train braking, and in particular relates to an outsourcing friction block for high-speed train braking. Background technique [0002] As the high-speed railway network becomes more and more criss-crossed, the safety of high-speed trains is getting more and more attention. When the train runs from high speed to safe braking and stops, the braking system needs to generate braking torque to complete the braking. The friction block directly contacts the wheel, and the kinetic energy is converted into heat energy through friction and dissipated into the air. Therefore, the performance requirements of the friction block are very high. The friction block is generally formed by pressurized sintering of the friction block compact and the friction block steel back, and the friction block compact and the friction block steel back have structures corresponding to each other. However, since the powder metallurgy fri...
