Abstract

FIELD: railway transport.

SUBSTANCE: invention relates to railway transport, namely, to brake shoes of the brakes of a railway vehicle. Brake shoe of a railway vehicle comprises at least a single-layer composite friction element, pressed into the rear part whereof are a perforated curved steel strip and a wire cage made of a frame of the back of the shoe, bent from wire along the perimeter of the rear side of the shoe, the ends whereof are connected, the ends of the wire are connected without an increase or with an increase in the thickness of the wire frame along the thickness of the cage and the second frame of the boss of the shoe, connected with the frame of the back of the shoe by contact or electric arc welding, forming an eye for the cotter hole.

EFFECT: increase in the vibration strength of the brake shoe.

1 cl, 1 dwg

Description

Изобретение относится к области железнодорожного транспорта, а именно к тормозным колодкам железнодорожных транспортных средств. Наиболее близким аналогом данного изобретения является Авторское свидетельство СССР №518403, В61 СССР №518403, В61 7/020, 1976 г. Тормозная колодка содержит однослойный композиционный фрикционный элемент, в тыльную часть которого впрессованы - перфорированная изогнутая стальная полоса и проволочный каркас.The invention relates to the field of railway transport, namely the brake pads of railway vehicles. The closest analogue of this invention is the Author's certificate of the USSR No. 518403, B61 of the USSR No. 518403, B61 7/020, 1976. The brake shoe contains a single-layer composite friction element, in the back of which a perforated curved steel strip and a wire frame are pressed.

Проволочный каркас фиг. 1 выполнен из рамки спинки колодки поз. 1 согнутой из проволоки по периметру тыльной стороны колодки концы которой соединены, соединение концов проволоки выполнены без увеличения либо с увеличением толщины проволочной рамки по толщине каркаса и второй рамки бобышки колодки поз. 2, соединенной с рамкой спинки колодки методом контактной или электродуговой сварки, образуя ушко для отверстия под чеку.The wire frame of Fig. 1 is made from the frame of the back of the block pos. 1 bent from wire along the perimeter of the back side of the pad, the ends of which are connected, the connection of the ends of the wire is made without increasing or with increasing the thickness of the wire frame along the thickness of the frame and the second frame of the boss of the pad, pos. 2, connected to the frame of the back of the pad by contact or electric arc welding, forming an eyelet for a hole for the pin.

Claims

Brake shoe of a railway vehicle, containing at least a single-layer composite friction element, into the rear part of which a perforated curved steel strip and a wire frame are pressed, characterized in that the wire frame is made of a back frame of the shoe, bent from wire along the perimeter of the back side of the shoe, the ends which are connected, the connection of the ends of the wire is made without increasing or with an increase in the thickness of the wire frame along the thickness of the frame and the second frame of the boss of the block, connected to the frame of the back of the block by contact or electric arc welding, forming an eyelet for a pin hole.
