Description

A kind of single centre pin type hitch structure and framework
Technical field
The present invention relates to rail vehicle truck, in particular to a kind of single centre pin type hitch structure and framework.
Background technique
Rail vehicle tends to be compact in design space under the technical requirements such as multipurpose, narrow limit.Draft gear of bogie is The component of vehicle tractive force and brake force is transmitted, intensity requirement is very high.How to meet tight space at the same time and high intensity is wanted Optimizing the design of traction device structure in the case where asking is problem to be solved.
There are many existing traction device structural shape, centrepin duplex pull rod etc. with pull rod structure design obviously to occupy compared with Large space is not suitable for tight space installation.Chinese patent ZL201310623687X discloses a kind of floating type centrepin traction Device is as shown in Figure 1 and Figure 2, and rubber bushing 4, rubber bushing 4 are inlayed in the traction key seat 2 being mounted on vehicle body bottom frame sleeper beam It is sulfided by rubber sleeve and steel sleeve, centrepin 1 and copper sheathing 3 are interference fitted, and rubber bushing 4 is fixed on centrepin with end plate The steel sleeve bottom of 1 bottom end, rubber bushing 4 is installed on end plate 5.Although this structure is adapted to tight space and installs, but by Between copper sheathing 3 and rubber bushing 4, rubber bushing 4 and traction key seat 2 between be respectively clearance fit, wear away it is larger;Copper sheathing 3 and rubber Though applying lubricating grease when installing between glue bushing 4 but lubricant effect can not be kept for a long time, and main wear member copper sheathing 3 is not easy to replace; The gap of centrepin 1 and traction key seat 2 is not easy to control when assembling, so that assembly is had difficulties, vehicle launch rushes if gap is larger It hits larger.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide that a kind of installation is simple, and buffering is more Good, main wear member replaces convenient single centre pin type hitch structure and framework.
In order to solve the above technical problems, the present invention provides a kind of single centre pin type hitch structure, including centrepin and pin Seat, the bottom setting of the centrepin have the rotary table of the conical surface;The key seat is fixedly installed on framework, the traction key seat Centrepin mounting hole is arranged in middle part, and interference fit is arranged rubber arthrosis on the rotary table of the centrepin, and the rubber arthrosis is set It is placed in the centrepin mounting hole, is horizontally equipped between the rubber arthrosis and the inner wall of the centrepin mounting hole big Gap value in two system's transverse direction stop gaps, sets between the rubber arthrosis and the inner wall of the centrepin mounting hole in the longitudinal direction There is cushion block, clearance fit is arranged between any two for the traction key seat, cushion block, rubber arthrosis.
Present invention omits copper sheathing in the prior art, innovation uses the bottom conical surface in integral rubber joint and centrepin Interference fit, be conducive to the rubber arthrosis in the case where being less than coefficient of friction formed with centrepin it is self-locking, in addition in the longitudinal direction in Increase cushion block between rubber arthrosis and the centrepin inner wall of the hole installing for drawing key seat, by the cushion block for selecting suitable dimension Reduce cushion block as far as possible and draw the gap between key seat and rubber arthrosis, to substantially reduce launch train and braking When instantaneous impact to improve the reliability of package unit.Simultaneous buffering cushion block and rubber arthrosis cooperation realize that framework is longitudinal double Grade buffering, and cushion block is simple as main wear member installation and replacement, and can apply lubricating grease or lubrication in main mating surface Oil is to mitigate abrasion and shorten the replacement cycle.
Further, the rubber arthrosis includes the inner metal layer being wholely set, intermediate rubber layer and outer metal layer;It is described The first supporting plate is installed in the bottom surface of centrepin, and the middle part of the first supporting plate has a boss contacted with the bottom surface of the inner metal layer, Certain interval is reserved in the periphery of first supporting plate and the bottom surface of the outer metal layer, and covering is without departing from described outer in horizontal direction Metal layer, in this way, when car body operates normally, when car body has small floating relative to bogie, due to intermediate rubber layer elasticity Deformation, so that only inner metal layer and intermediate rubber layer float rubber arthrosis with car body, and in car body lifting, due to pallets level The outer metal layer of rubber arthrosis is covered on direction, so that whole rubber arthrosis floats with car body.
Further, the second supporting plate is installed in the bottom surface of the traction key seat, and the second supporting plate extends to the cushion block Bottom, to avoid cushion block abjection.
Further, second supporting plate is in the horizontal direction without departing from the range of the cushion block, to avoid second Supporting plate stops centrepin assembling to float up and down, and only plays the role of that cushion block is avoided to deviate from.
Further, the taper of the conical surface is less than 1:5.
Further, the centrepin mounting hole is square hole.
Further, it is separated by 15mm between the periphery of first supporting plate and the bottom surface of the outer metal layer.
Further, gap is less than 0.5mm between any two for the traction key seat, cushion block, rubber arthrosis.
In order to solve the above technical problems, the present invention also provides a kind of structures suitable for the single centre pin type hitch structure Pin hole is arranged on crossbeam in frame, and the traction key seat is fixedly installed below the pin hole, and the bottom of the centrepin passes through institute It states pin hole and is interference fitted with the rubber arthrosis being located in the traction key seat, and installation two is lateral damper on the centrepin Mounting base.
In order to solve the above technical problems, the present invention also provides a kind of structures suitable for the single centre pin type hitch structure The traction key seat, the bottom of the centrepin and the rubber being located in the traction key seat is fixedly installed in frame, crossbeam side Joint interference fit.
Compared with the prior art, the advantages of the present invention are as follows:
(1) present invention realizes the compact design of no draw bar, saves design space while meeting large traction high intensity It is required that the frame design that centrepin therein interts crossbeam mounting means can also realize that integrated two be lateral damper installation;
(2) it is realized in the longitudinal direction by integral rubber joint and cushion block between centrepin of the invention and framework mounting base Dual-stage buffer tractive force and brake force impact;
(3) present invention also achieves the accurate adjusting of axial clearance between centrepin and framework by the way that cushion block is arranged, and reducing should Gap can further decrease vehicle launch and braking impact;
(4) cushion of the invention is wear part, is designed using easily changeable structure, while can be by applying lubricating oil or lubricating grease Loss is reduced to shorten the replacement cycle.
