Description
Technical field
The utility model relates to the shock absorber on a kind of rail traffic vehicles, particularly a kind of central buffering adaptor union.
Background technology
In the rail traffic vehicles technology, the central buffering adaptor union is two adjacent compartments that are used to connect train, and forms the mechanical type connection of locking.The adapter shaft of central buffering adaptor union is designed so that adaptor union can carry out the swing of vertical and level and axial moving, and this hunting motion for example occurs when train curve travels.The damage that impact that occurs in train is shunt process or at glancing impact or vibration can cause vehicle or adaptor union itself, for fear of this damage, be necessary to limit as much as possible the transmission of this impact, vibration etc., promptly require in adaptor union, to be provided with the elastic element that absorbs impact, vibration, and utilize the mount pad that is provided with to determine to be delivered on the car body connecting panel after peaked tractive force and impulsive force are through the elastic element buffering.The elastic element distortion absorbs energy, therefore prevents that the car body underframe that comprises the car body connecting panel is subjected to excessive load.
As shown in Figure 1, it is the structure of existing central buffering adaptor union, this central buffering adaptor union all is same group of elastic element of extruding when being subjected to tractive force and impulsive force, the assembling of known elasticity element is that certain precompressed compression is arranged, therefore precompressed compression becomes the initial pressure of energy disperser, when when the tractive force between the vehicle or impulsive force surpass the precompressed compression of elastic element, less tractive force and impulsive force occurring between the vehicle, buffer coupling does not play buffer action, be rigid shock between the buffer coupling, this impact is unfavorable for improving the traveling comfort that the passenger takes and the service life of parts; In addition, make complex-shaped pipe link, housing and articulated mounting, making and maintenance cost are higher.
Summary of the invention
Less tractive force or the impulsive force of appearance also can play buffer action and central buffering adaptor union simple in structure between a kind of vehicle even the purpose of this utility model is to provide.
In order to achieve the above object, the technical solution of the utility model is: a kind of central buffering adaptor union, comprise adapter shaft and mount pad, and adapter shaft has preceding pressure-bearing section and back linkage section; Also comprise first elastic element, intermediate hsg, second elastic element, elastic element pressing plate and pretension element; Has elastic element backstop on the back linkage section of described adapter shaft; Described first elastic element, intermediate hsg, second elastic element and elastic element pressing plate are sleeved on the back linkage section of adapter shaft successively easy fit, one end and the elastic element backstop of first elastic element offset, one side of the other end of first elastic element and intermediate hsg offsets, one end of second elastic element and the opposite side of intermediate hsg offset, and the other end of second elastic element and elastic element pressing plate offset; Described pretension element is contained in the end of back linkage section and offsets with the elastic element pressing plate; The two ends of described intermediate hsg are respectively equipped with first rotating shaft and second rotating shaft, and first rotating shaft and second rotating shaft are hinged with the two ends of mount pad respectively.
Described mount pad comprises car body butt flange, the first protruding wing and the second protruding wing, the car body butt flange and the first protruding wing and the second protruding wing load or make one, has the first hinged hole on the first protruding wing, has the second hinged hole on the second protruding wing, first rotating shaft of intermediate hsg and second rotating shaft respectively with the first hinged hole and the second hinged hole normal-running fit, have several connecting bores on the car body butt flange.
The front portion of the front portion of the described first protruding wing and the second protruding wing interconnects by first brace rod and second brace rod.
Described first elastic element has two.
Have 4 connecting bores on the car body butt flange of described mount pad.
The end of the back linkage section of described adapter shaft has outside thread, and the pretension element is a nut, and this nut is screwed on the outside thread of back linkage section, and locking pin also is housed on the back linkage section, and locking pin is positioned at the nut outside.
After adopting said structure, because first elastic element and second elastic element are distributed in the intermediate hsg both sides, and utilize the pretension element to carry out precompressed, at this moment the precompressed compression of first elastic element of intermediate hsg both sides and second elastic element is cancelled out each other, when adapter shaft is subjected to the tractive force of any size or impulsive force, all will compress intermediate hsg wherein the elastic element of a side carry out bumper and absorbing shock, the elastic element of opposite side is spreading thereupon then.Even produce very little tractive force and impulsive force between the vehicle, first elastic element and/or second elastic element all will play buffer action, cushion the application force between the vehicle, avoid the rigid shock of connecting portion, improve the traveling comfort and the safety of train operation.Because first rotating shaft and second rotating shaft at intermediate hsg two ends are hinged with the two ends of mount pad respectively, and the utility model can be hinged on the car body connecting panel of rail traffic vehicles with horizontally rotating, therefore when travelling, train curve also can play buffer action again.In addition, the utility model does not need complex-shaped pipe link, housing and articulated mounting, make simple in structure, make and maintenance cost low.
