Title:
RAILWAY VEHICLE DISC BRAKE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/103883
Kind Code:
A1
Abstract:
Provided is a railway vehicle disc brake apparatus that is capable of ensuring sufficient strength to withstand a reaction force from a disc, and that can be reduced in weight. A caliper lever (3a) of the railway vehicle disc brake apparatus has a pair of working point side arms (29a, 30a), and a working point section (32a). The working point section (32a) links the pair of working point side arms (29a, 30a), and holds a pad via a working point shaft. The pair of working point side arms (29a, 30a) are inclined in such a manner that the interval therebetween narrows as the working point side arms approach the working point section (32a). Furthermore, each working point side arm (29a, 30a) is inclined with respect to a reference plane (P3) that is perpendicular to the direction in which the working point section (32a) extends.
