Abstract

Изобретение относится к области транспортного машиностроения и касается фрикционных амортизаторов транспортных средств, преимущественно поглощающих аппаратов, устанавливаемых между вагонами железнодорожного состава. Задача - повышение стабильности и надежности фрикционного амортизатора, а также повышение его энергоемкости. Фрикционный амортизатор содержит корпус (1) с днищем (2) и с образованной стенками (3) горловиной (4), в которой расположен клиновой узел (5), содержащий нажимной клин (6) и распорные клинья (7). Между днищем (2) и клиновым узлом (5) расположено упругое устройство (8), образованное распорным демпфером (9) и подпорным демпфером (10), между которыми расположен разделитель (11). Распорные клинья (7) выполнены с возможностью обеспечения их контакта с направляющими элементами (N) в горловине (4) и снабжены обращенными к днищу (2) опорными элементами (E) с обеспечением возможности взаимодействия ими с распорным демпфером (9) при приложении внешних сил (q, Q) к клиновому узлу (5). В направлении к вершине горловины (4), начиная от разделителя (11), расположен толкатель (12) без возможности передачи всей нагрузки подпорному демпферу (10) от распорных клиньев (7) при приложении внешних сил (q, Q) к клиновому узлу (5), чем достигается технический результат решения задачи изобретения. Описаны также другие его отличительные признаки и связи между ними.The invention relates to the field of transport engineering and relates to friction shock absorbers of vehicles, mainly draft gears, installed between the cars of the train. The task is to increase the stability and reliability of the friction shock absorber, as well as to increase its energy consumption. The friction shock absorber contains a housing (1) with a bottom (2) and a neck (4) formed by walls (3), in which a wedge assembly (5) is located, containing a pressure wedge (6) and spacer wedges (7). Between the bottom (2) and the wedge unit (5), there is an elastic device (8) formed by a spacer damper (9) and a back-up damper (10), between which a separator (11) is located. The spacer wedges (7) are made with the possibility of ensuring their contact with the guide elements (N) in the neck (4) and are equipped with supporting elements (E) facing the bottom (2) so that they can interact with the spacer damper (9) when external forces are applied (q, Q) to the wedge knot (5). Towards the top of the neck (4), starting from the separator (11), there is a pusher (12) without the possibility of transferring the entire load to the retaining damper (10) from the spacer wedges (7) when external forces (q, Q) are applied to the wedge assembly ( 5), than the technical result of solving the problem of the invention is achieved. Its other distinctive features and connections between them are also described.
