Description
Technical field
The utility model is No. 13 hitches about a kind of used for rail vehicle, relates in particular to a kind of structure that prevents the knuckle pivot pin bending of No. 13 hitches.
Background technology
No. 13 hitches are a kind of hitches that rail freight and electric power, diesel locomotive generally use, as depicted in figs. 1 and 2, described No. 13 hitches mainly include hitch body 1, hook tongue 2 and knuckle pivot pin 3, these hitch body 1 one sides are ㄈ shape structure 11 (as shown in Figure 3, Figure 4), the upper and lower end parts of this ㄈ shape structure 11 is provided with through hole 111, and the upper and lower end parts opposed inside of this ㄈ shape structure 11 is provided with guard pin platform 112; Described hook tongue 2 is arranged on the indentation, there (as Fig. 1 and shown in Figure 5) of the upper and lower end parts of ㄈ shape structure 11, with described through hole 111 corresponding perforation 21 (as Fig. 6, shown in Figure 7) that are provided with, described knuckle pivot pin 3 after passing through hole 111 and perforation 21 is articulated described hitch body 1 and hook tongue 2 on the hook tongue 2; The upper and lower end parts contact site of described hook tongue 2 and ㄈ shape structure 11 is provided with the guard pin nest 22 that matches with described guard pin platform 112.Described No. 13 hitches in use present three kinds of states, are called for short ternary; First kind of state is hook tongue standard-sized sheet position, and this state hook tongue standard-sized sheet must keep accurate position, and the company of preparation hangs, this moment hook tongue 2 by knuckle pivot pin 3 location, knuckle pivot pin and hitch body, hook tongue room are more little, hook tongue position is accurate more, it is safe more to connect extension.Second kind of state is hook tongue closed position, the complete locking of this state hook tongue, be in the traction strained condition, the ring wall 221 of the guard pin nest 22 of hook tongue 2 is in contact with one another the transmitting tractive power (as shown in Figure 5) that is used for the guard pin platform 112 of hitch body 1 at this moment, and knuckle pivot pin 3 should be not stressed.The third state is unlock position (irrelevant with the utility model, as to repeat no more).
In the prior art, be provided with steel bushing 4 (as shown in Figure 5) between hitch body 1 and the knuckle pivot pin 3; But because the elasticity of steel is bad, described steel bushing 4 does not have deformability, if excessive clearance can make No. 13 hitches when first kind of state, hook tongue open position is inaccurate, and influence connects hangs safety; If the gap is too little, can make No. 13 hitch stressed bendings of knuckle pivot pin when second kind of state.In existing actual the use, because knuckle pivot pin 3 stressed bendings are caused often greater than the gap between steel bushing 4 and the knuckle pivot pin 3 in the gap between guard pin platform 112 and the guard pin nest 22.
Above problem does not have good method to solve for a long time, makes system-wide every year a large amount of knuckle pivot pin bendings be arranged, and the loss that causes is very huge, and serious crooked knuckle pivot pin is stuck in hook tongue inside and gets to come out, and can cause hitch to scrap.Therefore, now demand needing to solve the problem of knuckle pivot pin bending urgently.
The utility model content
The purpose of this utility model is to provide a kind of structure that prevents the knuckle pivot pin bending of No. 13 hitches.
The purpose of this utility model is to realize like this, a kind of structure that prevents the knuckle pivot pin bending of No. 13 hitches, this structure includes hitch body, hook tongue and knuckle pivot pin, this hitch body one side is provided with a ㄈ v notch v, the upper and lower end parts of this ㄈ v notch v is provided with through hole, and the upper and lower end parts opposed inside of this ㄈ v notch v is provided with the guard pin platform; Described hook tongue is arranged on ㄈ v notch v place, correspondingly with described through hole on the hook tongue is provided with perforation, and described hook tongue is provided with the guard pin nest that matches with described guard pin platform with the upper and lower end parts contact site of ㄈ v notch v; Described knuckle pivot pin passes through hole and perforation is articulated described hitch body and hook tongue; Be provided with the elasticity body between the through hole of described hitch body and the knuckle pivot pin.
In a better embodiment of the present utility model, described elasticity body is the rubber body.
In a better embodiment of the present utility model, described elasticity body is the plastics body.
In a better embodiment of the present utility model, described elasticity body is the spring body.
In a better embodiment of the present utility model, described spring body is waney coil spring.
From the above mentioned, the utility model can guarantee that knuckle pivot pin is no longer stressed owing to be provided with the elasticity body between the through hole of hitch body and knuckle pivot pin, therefore, can avoid the situation of the stressed bending of knuckle pivot pin in the prior art to take place.
