Abstract
Disclosed is a connecting joint for railway wagon, which comprises a nut connecting block, a hinge connecting block, a traction pin, a hemispherical pad, a concave spherical pad and a wedge pad, which is characterized in that the female and hinge connecting block is separately fixed to the ends of two neighboring vehicles and is not joined on the bogie. The single-chip joint head of the hinge connecting block is inserted between the double chips joint head of the female connecting block; a space is left vertically between single-chip joint head of the hinge connecting block and the double chips joint head of the female connecting block, allowing mutual dislocation vertically; the nut and hinge connecting blocks are connected by a cylindrical traction pin. The hole of the hinge connecting block is spherical and a hemispherical pad is provided between the traction pin and the spherical hole of the hinge connecting block; the front part of the hinge connecting block head is convex spherical, corresponding with the concave spherical pad, and the wedge pad is added between the concave spherical pad and the slant of the female connecting block, composing a spherical hinge with no-gap connection vertically and rotating in all directions.
Description
Technical field
The utility model relates to a kind of method of attachment and device of railway vehicle, is a kind of method of attachment and device of articulated type rail freight specifically, belongs to railway transportation equipment field.
Background technology
The jockey of traditional rail freight is coupler and draft gear and draw bar.Can adopt joint connector (Articulated Connector) to the vehicle that need not decompose in using.Adopt the joint adaptor union simpler, can reduce dead weight of vehicle and manufacturing, the cost of overhaul with coupler and draft gear or draw bar structure.And existing joint adaptor union is to be seated in the shared bogie truck cartridge of two continuous cars of joint by the cartridge that is connected on the female connectors body, and the public connector body is pressed in the cartridge of female connectors body by protruding, concave spherical surface pad.The vertical load of joint car end reaches on the shared bogie truck of two cars by female, public connector body.Because two cars share bogie, full axletree number is few, and under the condition that axle heavily limits, the load-carrying of vehicle also is restricted, and is not suitable for the railway heavy haul transport needs.
Summary of the invention
The purpose of this utility model provides and is a kind ofly overhang and be not bearing in connection hinge on the bogie truck by the car end, is applicable to the not joint car of shared bogie truck.So that the joint vehicle-mounted great, from heavy and light, make and the cost of overhaul low.
For achieving the above object, the connection mode that the utility model joint car connects hinge adopts the male and female connection free bearing ways of connecting that is not bearing on the bogie truck to connect, and joint car male and female connection free bearing is directly carried out the vertical hanging structure level that does not stress with two adjacent vehicle ends and is connected.Connecting hinge comprises female free bearing, male connector hinge seat, towing pin of connecting.Female connection free bearing, male connector hinge seat adopt respectively hanging structure to be fixed in two adjacent vehicle ends.Between the monolithic hinge head of male connector hinge seat is inserted among female biplate hinge head that connects free bearing, the vertical gap of leaving between the monolithic hinge head of male connector hinge seat and female biplate hinge head that is connected free bearing, allow its vertical mutual changing of the relative positions, male connector hinge seat and female free bearing that is connected are in vertical direction holding capacity not.The connection free bearing is connected free bearing with mother and is linked together by cylindrical towing pin.The public hole that connects free bearing is a sphere, is connected between the ball hole of free bearing (being subjected to direction of draw) at towing pin with public affairs the hemisphere face pad is housed; Public to connect free bearing head front end be protruding sphere, and what match with it has a concave spherical surface backing plate, is connected between the free bearing inclined-plane with female at the concave spherical surface backing plate, adds razor-edge liner again, makes its composition vertically be seamless connectivity and ball pivot that can universal rotation.
After adopting such structure, this connection hinge can be transmitted longitudinal force and the transverse force between vehicle, does not transmit vertical force.Have simple in structure, from advantages such as heavy and light, manufacturing and the cost of overhaul are low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are described in further detail.
Referring to Fig. 1, the utility model is connecting hinge, the mode that the connected mode of joint car connecting hinge adopts the male and female that is not bearing on the bogie to connect the free bearing connection connects, and joint car male and female connects free bearing and directly carries out the vertical hanging structure level connection joint that does not stress with two adjacent vehicle ends.Car connection hinge in joint connects free bearing 1, public connection free bearing 3, towing pin 2, hemisphere face pad 4, concave spherical surface backing plate 5 and razor-edge liner 6 by mother and forms.Female connection free bearing 1 is fixed in the car end of car body 7, and public connection free bearing 3 is fixed in the car end of car body 8.The monolithic hinge head of male connector hinge seat 3 is inserted between the biplate fork-shaped hinge head of female connection free bearing 1.The vertical clearance C that leaves between the monolithic hinge head of male connector hinge seat 3 and female biplate hinge head that is connected free bearing 1 allows its vertical mutual changing of the relative positions, and male connector hinge seat 3 is connected free bearing 1 in vertical direction holding capacity not with mother.The female connection on the free bearing 1 is shaped with circular hole.Be shaped with the ball hole on the male connector hinge seat 3, (front position) is equipped with the hemisphere face pad 4 with semicircle orifice in the ball hole, columniform towing pin 2 penetrates female circular hole that connects free bearing 1 upper slice hinge head, by the circular hole of the hemisphere face pad 4 in the male connector hinge seat 3 of packing into, penetrate again female circular hole that connects 1 time sheet hinge head of free bearing again.Public to connect free bearing 3 a hinge front end be protruding sphere, and what match with it has a concave spherical surface backing plate 5, adds and mother is connected the razor-edge liner 6 that the inclined-plane of free bearing 1 matches, and formed vertically be seamless connectivity and ball pivot that can universal rotation.
After adopting such structure, the utility model connecting hinge makes two joint cars form articulated type. Can transmit Longitudinal force between vehicle and cross force are not transmitted vertical force. Simple in structure, deadweight that this connecting hinge has Gently, use after the abrasion vertically gapless, and manufacturing is hanged down advantage with the cost of overhaul. Be applicable to fixedly at the bottom of the car The vehicle of special train transportation.
Claims (2)
1, a kind of rail truck connecting hinge comprises female free bearing, male connector hinge seat, towing pin of connecting, and it is characterized in that: female connection free bearing, male connector hinge seat adopt respectively hanging structure to be fixed in two adjacent vehicle ends; Between the monolithic hinge head of male connector hinge seat is inserted among female biplate hinge head that connects free bearing, the vertical gap of leaving between the monolithic hinge head of male connector hinge seat and female biplate hinge head that is connected free bearing, allow its vertical mutual changing of the relative positions, male connector hinge seat and female free bearing that is connected be in vertical direction holding capacity not, connects free bearing and be connected free bearing with mother and linked together by cylindrical towing pin.
