Abstract

The invention relates to the technical field of rail vehicle braking and discloses an axle-mounted brake device for a gauge-changeable wheel set. The axle-mounted brake device for the gauge-changeablewheel set comprises a transitional sleeve, a locating mechanism and a plurality of axle-mounted brake discs; the plurality of axle-mounted brake discs are fixed on the transitional sleeve at intervals; the transitional sleeve is connected with an axle of the gauge-changeable wheel set through a spline in a matched manner; and the locating mechanism is used for connecting the transitional sleeve with the axle so as to axially locate the transitional sleeve relative to the axle. According to the axle-mounted brake device for the gauge-changeable wheel set, by improving the connection modes between the axle-mounted brake discs and the axle, the relative positions of a brake clamp and the axle-mounted brake discs can be kept invariable during changing the gauge so that braking effects at different gauges are realized.

Description

technical field [0001] The invention relates to the technical field of rail vehicle braking, in particular to an axle-mounted braking device for a wheel set with variable gauge. Background technique [0002] In order to meet the transportation requirements between tracks of different gauges in neighboring countries, bogies with different inner distances of wheel sets are often replaced at the junction. This solution is costly and time-consuming. Spain and Japan successively invented variable-gauge bogies, which can run continuously between tracks of different gauges. [0003] In order to realize the parking brake of the train, especially the trailer, the shaft-mounted brake disc is usually installed on the axle of the trailer. When braking, the brake caliper is used to hold the shaft-mounted brake disc to realize the parking brake. In the case of changing the track gauge, keeping the relative position of the brake caliper and the shaft-mounted brake disc unchanged is a prob...
