Abstract

The invention discloses a brake block holder and a braking device. The brake block holder comprises a holder body, a roller and a roller shaft, wherein the holder body is provided with an anti-run wing plate which is used for blocking the roller from rolling out of a side frame chute of a bogie. Through the anti-run wing plate arranged on the holder body, no matter what adverse working condition is, the brake block holder can ensure that the roller always rolls inside the side frame chute of the bogie, thereby effectively avoiding brake beam component falling caused by the roller rolling out of the chute, preventing braking failures, and improving the driving safety.

Description

technical field [0001] The invention relates to vehicle braking technology, in particular to a brake shoe holder and a braking device. Background technique [0002] The brake shoe support (that is, the mounting seat of the brake shoe) is installed on the brake beam, and is an important part of the braking device of the railway vehicle and its bogie. It can be used to provide safe fixation and positioning of the brake shoe, and provide a The tiles transmit braking force efficiently. Generally speaking, a single-side brake shoe braking method is adopted, that is, one wheel of a railway vehicle corresponds to a pair of brake shoes and a brake shoe holder. [0003] figure 1 Schematic diagram of the structure of the braking device provided for the prior art, such as figure 1 As shown, the braking device is composed of side frame chute 1 of the bogie, brake shoe (not shown in the figure), brake shoe support 2 and brake beam frame 3, wherein the brake shoe support 2 and brake be...
