Definitions
- the invention relates to a braking device of the shoe type for railway material intended to run on networks between which the tracks have different spacings.
- railway equipment comprises a chassis carried by at least one axle at the ends of which are wedged wheels spaced from each other by a value determined according to the difference between the rails of a determined network and under which chassis is installed a shoe type braking device comprising for each wheel:
- - a wheelhouse and at least one pair of shoes which are arranged in zones substantially diametrically opposite of the wheel in the manner of jaws so that, when braking, the wheelhouse maneuvers the shoes to pinch the tread of the wheel between them .
- the shoes are each carried by a support connected to the chassis by a suspension means allowing the movement of the shoe considered in the same plane as that containing the wheel.
- the suspension means generally consists of a suspension link.
- the difference in length between the two types of axles is sufficient to use two shoes mounted on the chassis, but it sometimes happens that the treads on which the shoes rest are, in axial positions, completely distinct at the along the axis of the axle but the width of these strips increased by the thickness of the flanges of these wheels is such that the areas reserved for their passage are close or even overlap and at least, in the use of the one of the axles, if the two pairs of shoes were ordered simultaneously, the pair of shoes which is not intended for the type of axles considered, could come, if only through games, in contact with the outer edge of the wheel and at least prevent the shoe actually assigned to the wheel in question from coming to rest on the tread and allowing the braking action. Given the space available, it is not conceivable to provide a second wheelhouse to make the operation of pairs of shoes independent.
- a braking device notably characterized in that it comprises:
- each support two shoes, each adapted to the profile of the wheel used on a different network
- a locking means in translation of at least the movable shoes in predetermined positions.
- FIG. 1 a partial side view of railway equipment
- FIG. 2 and 3 a top view of a braking device according to the invention in two operating positions.
- railway equipment 1 in order to run on two railway networks with a track gauge difference between them, railway equipment 1 is used, on which axle interchangeability means are provided for adapt them to the spacing of the network tracks to be used.
- each railway material comprises a chassis 2 carried by at least one axle 3 at the ends of which are chocked wheels 4 spaced from one another by a value determined as a function of the difference between the rails and under which chassis a shoe type braking device 5 is arranged comprising for each wheel a wheelhouse and at least one pair of shoes 7a, 7b ⁇ i its "arranged in zones substantially diametrically opposite of the wheel in the manner of jaws so that, when braking, the wheelhouse maneuvers the shoes to pinch the tread between them.
- the shoes 7a, 7b are each carried by a support 8 connected to the chassis by means 9 of suspension authorizing the movement of the shoe considered in the same plane as that containing the wheel.
- This suspension means generally takes the form of a suspension link.
- the braking device comprises
- each support 8 two shoes 7a, 7b, each adapted to the profile of the wheel used on a different network, - a shaft 10 parallel to the axis of the axle 3 on which at least one of the shoes, said movable shoe, is mounted to slide, which shaft is long enough to allow at least said movable shoe to move between two positions, one called the active position where it is opposite the wheel to which it is assigned and the other so-called waiting position where it is sufficiently spaced from the previous position so that, during the operation of all the shoes, the trajectory of the shoes in the waiting position does not intersect with the wheels then used and,
- the movable shoes then comprise a means 12 for guiding in translation on the shaft, such as a bore 12 formed in the support on which they are fixed.
- the shoes placed as close as possible to the median axis of the railway material which are mobile.
- the locking means consist of the rod of a pin which engages in a bore that has the support of the shoe and the shaft.
- the locking means 11 is an eclipsable stop 13 which: - on the one hand, has its transverse dimension D measured along the axis of the shaft substantially equal to the unoccupied length of the tree and, - on the other hand, is movable in translation along the axis
- the two shoes are movable and the eclipsable stop 13 is constituted by two individual shims 13a, 13b whose sum of thicknesses is equal to the total thickness of the eclipsable stop 13 so that, depending on the position of the shims, the distance between the shoes and their position on the shaft is such that there is no risk that the shoe, which is not temporarily in service, intersects with the wheel flange.
- the eclipsable stop 13 instead of the eclipsable stop 13 being movable in translation, it has complementary movable shapes with the shoe .. to lock it in its positions.
- the eclipsable stop 13 is carried by the rod 17 of an operating means, which rod is parallel to the shaft and movable in rotation.
- these supports are both carried by a rod 18 whose ends are guided in rotation and immobilized in translation on the suspension links which connect them to the chassis.
