Abstract

The utility model provides a coupler knuckle push iron and a car coupler. A matching face of the coupler knuckle push iron and a coupler knuckle thrower has a pointed intersection angle; and the car coupler comprises a car coupler head, a car coupler body and a car coupler tail, wherein the car coupler head comprises the coupler knuckle thrower and the coupler knuckle push iron. In the coupler knuckle push iron and the car coupler provided in the utility model, the intersection angle of the matching face of the coupler knuckle push iron and the coupler knuckle thrower is improved, thereby improving the seat locking performance of the coupler knuckle thrower and further improving the unlocking effect of the car coupler.

Description

The hook tongue pushes away iron and hitch

Technical field

The utility model relates to a kind of hitch structure technology, relates in particular to a kind of hook tongue and pushes away iron and hitch.

Background technology

Rolling stock is the visual plant of railway transportation, is the means of delivery that is used for transporting passenger, shipment or makes other special purposes.It does not generally have engine installation, must become row to coupling of vehicles, could road along the line operation by locomotive traction.Hitch is the vitals of rolling stock, hangs, plucks and separate and transmitting tractive power and impulsive force in order to the company that realizes vehicle, and hitch generally is made up of gib head, coupler body and three parts of hook tail.The hitch that rolling stock uses in the prior art is mainly automatic car coupler, and so-called automatic car coupler just is meant to possess and just becomes to finish automatically the hitch release or connect the hitch of hanging when mentioning hook shadoof or car to car impact.Great majority are the articulated type hitch in the automatic car coupler, and its principal character is that the hook tongue that can rotate around knuckle pivot pin is arranged on the gib head.Fig. 1 is the structural representation of the hitch of prior art, Fig. 2 is the plan structure scheme drawing of hitch shown in Figure 1, as depicted in figs. 1 and 2, gib head generally includes hook tongue 1, knuckle pivot pin 2, lock iron 3, the hook tongue pushes away iron 4 and latch gear 5, in the releasing process of hitch, drive lock iron 3 by latch gear 5 and rise, and then make the hook tongue push away iron 4 promotion hook tongues 1, realize unlocking function around knuckle pivot pin 2 rotations.

The hook tongue pushes away the locking part of iron 4 as hitch, in use mainly act as: one, promote hook tongue 1 and rotate, when guaranteeing uncoupling hook tongue 1 is opened fully; Two, for lock iron 3 provides support platform, a lock position can be stablized, be in exactly to lock iron 3 after the release of assurance hitch.Therefore, the hook tongue pushes away the release performance that iron 4 directly influences hitch, if the release effect is bad, will have a strong impact on uncoupling efficient.

The utility model content

The utility model provides a kind of hook tongue to push away iron and hitch, to improve the uncoupling effect of hitch.

The utility model provides a kind of hook tongue to push away iron, and the angle of cut that described hook tongue pushes away the fitting surface of iron and lock iron is a wedge angle.

Aforesaid hook tongue pushes away iron, wherein, and described fitting surface surfacing.

Aforesaid hook tongue pushes away iron, preferably, and the described fitting surface surfacing in the inside 11mm scope of the described angle of cut.

The utility model provides a kind of hitch, comprises gib head, coupler body and hook tail, and wherein, described gib head comprises that the hook tongue that lock iron and the utility model provide pushes away iron.

As shown from the above technical solution, the hook tongue that the utility model provides pushes away iron and hitch, become the angle of cut by the angle of cut of fitting surface that will push away iron and lock iron by fillet, avoided, the fitting surface too small iron lock lock performance bad problem that cause excessive, lock iron seat lock effect when having improved release because of angle of cut place curving of casting.

Description of drawings

Fig. 1 is the structural representation of the hitch of prior art;

Fig. 2 is the plan structure scheme drawing of hitch shown in Figure 1;

The hook tongue that Fig. 3 provides for the utility model embodiment one pushes away the structural representation of iron;

Fig. 4 pushes away the local structure scheme drawing of iron for hook tongue shown in Figure 3;

Another hook tongue that Fig. 5 provides for the utility model embodiment one pushes away the local structure scheme drawing of iron.

Reference numeral:

1-hook tongue; The 2-knuckle pivot pin; 3-locks iron;

4-hook tongue pushes away iron; The 5-latch gear; The 6-fitting surface;

The 7-angle of cut; L-length.

The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment one

The hook tongue that Fig. 3 provides for the utility model embodiment one pushes away the structural representation of iron, Fig. 4 pushes away the local structure scheme drawing of iron for hook tongue shown in Figure 3, as shown in Figure 3 and Figure 4, in unlocking process, the hook tongue pushes away iron lock iron is played a supporting role, usually claiming the hook tongue to push away iron is fitting surface with the surface that lock iron contacts with each other, and the angle of cut 7 that the hook tongue pushes away the fitting surface 6 of iron and lock iron is wedge angle.During release, the hook tongue pushes away iron and provides support platform for lock iron, by the angle of cut 7 being set to wedge angle, has avoided excessive because of the curving of casting of the angle of cut 7, and fitting surface 6 is too little and the bad problem of lock iron seat lock that causes has improved the release performance.

In the present embodiment, the hook tongue pushes away iron and fitting surface 6 surfacings of locking iron, preferably, as shown in Figure 5, fitting surface 6 surfacings in the angle of cut 7 inside length L scopes, the value of L is 11mm, and lock iron seat lock problem of unstable during with the release avoiding causing because of fitting surface 6 surface irregularities has improved the seat lock performance of lock iron.

Embodiment two

The utility model embodiment two also provides a kind of hitch, comprises gib head, coupler body and hook tail, and wherein gib head comprises that the hook tongue that lock iron and above-mentioned any embodiment provide pushes away iron.By the hook tongue being pushed away the improvement of iron, improved the release performance of hitch, and then solved because of hitch release performance badly, divide group job to increase work capacity to train, thereby influence the problem of the turnover rate of vehicle.And just the hook tongue is pushed away iron and improve with the fitting surface of locking iron, do not change the existing structure that the car coupler knuckle pushes away iron, improvement cost is low, and is convenient and reliable.

The hook tongue that the utility model provides pushes away iron and hitch, by the improvement that the hook tongue is pushed away iron and lock the fitting surface angle of cut of iron, avoided the bad problem of hitch release performance effectively, improved the comformability that lock iron and hook tongue push away iron, improve the release effect, and then improved work efficiency.

It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
