Abstract
The utility model relates to a tightlock coupler, which comprises a coupler body, a convex cone of the front end of the coupler body, a convex cone containing cavity and a connecting portion of the rear end of the coupler body, wherein a coupler knuckle cavity is provided between the convex cone and the convex cone containing cavity, and a coupler knuckle which can rotate inside the coupler knuckle cavity is provided inside the coupler knuckle cavity, the coupler knuckle is fixedly connected with the uncoupling crank provided inside the inner cavity of the coupler body, and a crank spring is further provided inside the inner cavity of the coupler body, one end of the crank spring is connected with the uncoupling crank, and the other end is connected to a spring hanging seat of the connecting portion of the rear end of the coupler body. Because the cylinder and the spring are provided by disassembling, and the allocation mode that the upper portion and the lower portion are arranged in parallel is adopted, the designed free degree of the longitudinal space of the coupler is bigger, and the length of the coupler can be shortened markedly, the structure of the coupler becomes more compact, and the influence which is acted on the related mechanisms of the couple by the external environment is reduced.
Description
Technical field
The utility model relates to a kind of railway vehicle equipment, especially a kind of subway light rail hitch coupling device.
Background technology
Coupler device is one of the most most important parts of vehicle, plays the longitudinal force of quick connection railway vehicle, transmission train travelling process and decomposes the effect of the vehicle of interconnection extension mutually fast.
Worldwide, railway vehicle is divided into rigidity hitch and non-rigid hitch two big classes with hitch.For non-rigid hitch, two of the interconnection extension be hooked on each degree of freedom and can in limited range, move mutually mutually; And the rigidity hitch, the hitch that two companies hang over together fastens as one, and does not have mutual motion substantially, uses therefore that performance is better, wearing and tearing are littler, the vehicle operating comfort level is better.For the rigidity hitch, exist multiple pattern, as semi-permanent car coupler, draw bar etc., but wherein tight lock coupler is that performance is best, a kind of rigidity hitch of operation most convenient structure relative complex.Tight lock coupler connects hangs decomposable process as automatic car coupler (belonging to non-rigid hitch) flexibly and fast, with the tight lock coupler of automatic decomposer, even can decompose by driver's Long-distance Control hitch; Owing to be the rigidity hitch, tight lock coupler can reduce the longitudinal impulse of hitch greatly, improves vehicle riding comfort, reduces the wearing and tearing of hitch parts.
At present, tight lock coupler also exists certain deficiency, and compact not enough as structure, volume is bigger, because the structure of coupler-uncoupling cylinder makes that also the hitch longitudinal length is difficult to shorten or the like.
Summary of the invention
The purpose of this utility model is the deficiency at existing tightlock coupler existence, and a kind of novel tightlock coupler with spring and cylinder split setting is provided.
Technical solution of the present utility model is: a kind of tight lock coupler, the convex cone that comprises coupler body, coupler body front end, the connecting portion of convex cone containing cavity and coupler body tail end, be provided with coupler knuckle chamber between convex cone and the convex cone containing cavity, be provided with the hook tongue that can in coupler knuckle chamber, rotate in the coupler knuckle chamber, the uncoupling crank that is provided with in hook tongue and the coupler body inner chamber is affixed, also be provided with the crank spring in the coupler body inner chamber, one end of this crank spring is connected with the uncoupling crank, and the other end is connected on the spring hanging seat of coupler body end joint connection portion.
Preferably, the hook tongue is the semicircular pillar profile, and is rotatable as to be installed in the coupler knuckle chamber of coupler body, when vehicle towed, contacts transmitting tractive power by hook tongue periphery with the coupler knuckle chamber inner headed face.
Preferably, coupler body is provided with a side opening, and the uncoupling crank moves in side opening, and described side opening is provided with seal cover cap, and sealing covers and has a vertical strip hole that makes the uncoupling crank move therein.
Preferably, the top of convex cone connects vermicelli for coupler body, coupler body connect vermicelli up and down each design an airduct seat hole that is used to install air hose coupling arranged; Design is useful on the adapter plate that electrical cnnector is installed in the coupler body bottom,
Preferably, the same vertical direction of crank spring is provided with the uncoupling cylinder, and an end and the uncoupling crank of this uncoupling cylinder are hinged, and the other end is installed on the coupler body inwall.
The beneficial effects of the utility model are: because cylinder and spring are decomposed setting, and adopt parallel up and down layout type of arranging, therefore the longitudinal space Design freedom of hitch is bigger, hitch length just can shorten greatly, it is more compact that the hitch structure becomes, and reduced the influence of external environment to the hitch associated mechanisms.
