Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims Implement with the multitude of different ways of covering.
As Figure 1-Figure 4, the embodiment of the invention discloses a kind of hitches, including coupler body 1, Bidirectional buffering 2 and hook Tailstock 3, wherein hook tailstock 3 is mounted on the car body of rail vehicle by bolt, and coupler body 1 is used to even hang with another car body, two-way Buffer unit 2 includes U-shaped fork 4, prism rubber bumper 5 and mounting base 6, and main function is even hung or run in car body When buffering energy-absorbing, mounting base 6 be fixed on hook tailstock 3 or with hook tailstock 3 be integrally formed, be provided with mounting hole 7, prism Rubber bumper 5 is arranged in mounting hole 7, and one end of U-shaped fork 4 and coupler body 1 are affixed, the other end and prism rubber bumper 5 Pivot joint.Hitch length ruler is realized under conditions of guaranteeing same buffering vibration absorption ability by this kind of Bidirectional buffering 2 Very little 50% or more diminution, while the quality and volume of hitch are reduced, while prism rubber bumper 5 makes Bidirectional buffering 2 can bear the impact force from car body polarizers of big angle scope in plane, expand the range of buffering energy-absorbing.
It in the present embodiment, further include one for holding up the support base 8 of coupler body 1 when coupler body 1 is swung, the support base 8 One end and hook tailstock 3 are pivotally connected, and the other end extends near the front end of coupler body 1, and when hitch is during docking, can hold up can The coupler body 1 of rotation, convenient for the company of being mutually inserted in adjacent car body gib head and gib head hole extension.
In the present embodiment, the bottom of mounting hole 7 is provided with limited step 9, and one end of prism rubber bumper 5 passes through limit Position step 9 limits, and the other end is limited by the snap ring 11 in the annular groove 10 that is mounted in mounting hole 7, when needing replacing rib When column rubber bumper 5, it is only necessary to exit shaft 13 (usually pin), taking out snap ring 11 can be taken off changing prism rubber buffer Device 5, since the unitary moduleization of prism rubber bumper 5 designs, interchangeability is good, so as to realize vulnerable part prism rubber The quick-replaceable of buffer 5 further increases the Quick overhaul efficiency of present rail vehicle.
In the present embodiment, the center of prism rubber bumper 5 offers pivoted hole 12, and U-shaped fork 4 passes through pivot by one It connects the shaft 13 in hole 12 and is pivotally connected with prism rubber bumper 5, prism rubber bumper 5 is by rubber layer 14 and V-type steel disc 15 1 The molding of body formula, rubber layer 14 and V-type steel disc 15 are spaced apart from each other arrangement, not only ensure that buffer capacity by rubber, pass through simultaneously Steel disc ensure that the service life of prism rubber bumper 5, wherein the V-shaped structure of V-type steel disc is open toward and away from hook Body 1 and simultaneously towards pivoted hole 12 be arranged, the distance between adjacent V-type steel disc in the same side equalization.Wherein, steel disc is set as V-type Preferred structure of the structure without overtesting, shaft 13 can frequently occur forward or backward when perhaps moving when car body is even hung Movement, V-type steel disc relative to straight steel disc or the steel disc of waveform steel disc or other shapes, not only have the processing is simple (only It is simple to bend), while V-type steel disc and rubber layer 14 have bigger contact area, the effect of buffering energy-absorbing is more preferable.
In the present embodiment, a buffer unit 17 is also additionally provided between support base 8 and coupler body 1, buffer unit 17 wraps Include a resilient rubbber cushion 18, fixed block 20 and can be along the slip blade 19 that fixed block slides up and down, the bottom of resilient rubbber cushion 18 It is mounted on support base 8, the other end extends to the downside of coupler body 1, passes through the buffering energy-absorbing function of resilient rubbber cushion 18, coupler body 1 When moving downward during car body is even hung or moved, rigid shock will not occur with support base 8, fixed block 20 be mounted on On support base 8 and it is located at 1 two sides of coupler body, slip blade 19 is set on resilient rubbber cushion 18 and two sides are fastened on fixed block respectively In 20 sliding slot, when coupler body 1 is when deflecting, since the power of the pushing of coupler body 1 can act directly on slip blade 19, pass through Power can be evenly transferred on resilient rubbber cushion 18 by the switching of slip blade 19, thus make the uniform force of resilient rubbber cushion 18, To make, the effect of its buffering energy-absorbing is more preferable, the service life is longer.Meanwhile in the case where being located at the top of slip blade 19, coupler body 1 Side is connected with the first buffer plate 29, and the two sides of coupler body 1 are provided with the second buffer plate 30 for compressing coupler body 1, and second is slow It rushes backing plate 30 to be fixed on fixed block 20, to avoid the direct rigidity of the coupler body 1 of iron material matter, fixed block 20 and slip blade 19 The problems such as contacting bring abrasive vibration.
In the present embodiment, 1 two sides of coupler body are provided with the cylinder 21 that swings, and the cylinder 21 that swings includes the first cylinder body 22 and First piston bar 23, the first cylinder body 22 be mounted on hook tailstock 3, the end of First piston bar 23 is articulated on coupler body 1.Together When, further include uncoupling crank 24 on coupler body 1, the uncoupling cylinder 25 of a driving uncoupling crank 24 rotation be additionally provided on coupler body 1, Uncoupling cylinder 25 includes the second cylinder body 26 and second piston bar 27, and the second cylinder body 26 is pivotally connected with coupler body 1, second piston bar 27 and solution Hook crank 24 is pivotally connected.By up and down adjustment cylinder and left and right adjusting cylinder, meanwhile, uncoupling crank 24 is driven by uncoupling cylinder 25 And then hook bolt 28 is driven to complete the unlocking, it can be achieved that the automatic butt of gib head and de- when different compartment is even hung of the mutual gib head of the company of extension From.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification, Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
