RAILWAY VEHICLE DISC BRAKE APPARATUS

摘要

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 of the railway vehicle disc brake apparatus has a pair of working point side arms, and a working point section. The working point section links the pair of working point side arms, and holds a pad via a working point shaft. The pair of working point side arms are inclined in such a manner that the interval therebetween narrows as the working point side arms approach the working point section. Furthermore, each working point side arm is inclined with respect to a reference plane that is perpendicular to the direction in which the working point section extends.

1. A railway vehicle disc brake apparatus comprising:
a caliper lever configured to be pivotal about a predetermined fulcrum shaft so that a pad is movable in a direction extending toward a disc and in a direction extending away from the disc; and a drive device that drives the caliper lever about the fulcrum shaft, wherein the caliper lever includes
an effort-side arm coupled to the drive device,a fulcrum portion that extends from the effort-side arm and is coupled to the fulcrum shaft,two load-side arms that extend from the fulcrum portion, anda load portion that connects the two load-side arms to each other and holds the pad with a predetermined load shaft, the two load-side arms are inclined so that a distance between the two load-side arms decreases as the load portion becomes closer, and each of the load-side arms is inclined relative to a reference plane that is orthogonal to a direction in which the load portion extends.
