Problems solved by technology

[0003] At present, in the train disc brake system, the brake pads have unbalanced brake pressure during braking, which causes the brake disc to vibrate and cannot obtain the maximum effective friction area, resulting in a large thermal load during fatal braking and a reduced service life of the brake pads.

Abstract

The invention relates to a floating type train brake lining with replaceable friction blocks. The train brake lining is characterized in that the train brake lining comprises a brake lining back plate, a plurality of brake lining friction block bodies, a plurality of elastic supporting pieces and a plurality of round spring clips; installation holes are arranged on the brake lining back plate; elastic supporting pieces are provided with spherical supporting surfaces and central guide holes; lower portions of friction block bodies are provided with spherical supporting surfaces and positioning connection shafts with clamping grooves, and connection shafts can penetrate through central guide holes of elastic supporting pieces and positioning holes of the back plate and are locked on the back plate by round spring clips to achieve floating connection; and friction block bodies are polygonal block bodies with blind holes in centers, and every three friction block bodies form an interlocking group, so that rotation of friction block bodies during operation of the brake lining is prevented. By the aid of the brake lining, the maximum contact friction area between the brake lining and a braking disk can be obtained during braking of a train, so that the braking process is stable, functions such as damping, vibration absorption, noise reduction and heat dissipation are provided, friction block bodies are easy to replace, the operation cost of the train is reduced, and the brake lining can be widely used in braking systems of high-speed trains.

Description

technical field [0001] The invention relates to a disc brake device applied to high-speed trains, in particular to a floating train brake pad with replaceable friction blocks. Background technique [0002] With the increase of train speed, in order to ensure the braking performance of the train, the bogie foundation brake device generally adopts two types of disc brake devices, the axle disc and the wheel disc, and the brake pads directly rub against the brake disc to absorb kinetic energy. , so that the train brakes to stop. For high-speed trains, due to the relatively large braking energy, the brake pads, the key components of the disc brake device during braking: not only the friction blocks of the brake pads are required to be wear-resistant, high-temperature resistant, and low-noise, but also the friction blocks are required The body and its installed parts should have good heat conduction performance and load balance performance, etc. [0003] At present, in the disc...
