Abstract
The invention relates to a brake shoe key for a wagon. The brake shoe key is characterized by comprising a key body of an arc shape and a key head arranged at one end of the key body, wherein the key head and the key body are integrally arranged and are made of spring steel. A protruding part towards the outer side of the arc shape is arranged in the middle of the key body. The brake shoe key is made of the spring steel, the protruding part with certain elasticity is arranged in the middle of the key body and serves as a stop part, and therefore pre-tightening force to the nose part of a brake shoe is realized after the brake shoe key is assembled, the brake shoe and a shoe support can be closely matched under the conditions of stressing and non-stressing even if stressed parts are deformed in work, and gap generation is avoided.
Description
Technical field
The present invention relates to a kind of railway freight-car brake shoe key, belong to railway vehicle field.
Background technique
At present, the brake shoe of railway freight-car is connected on brake head by brake shoe key.The brake shoe key of the existing connected element as brake shoe and brake head, in the process that reality uses, there are some defects: existing brake shoe key is mostly forged by carbon structural steel and forms, in use because rigidity is low, brake shoe often occurs loosening phenomenon in utilization process, produce comparatively wide arc gap time, comparatively large to the impulsion of brake shoe when braking, the serious brake shoe that even causes ruptures.
Summary of the invention
For the problems referred to above, the object of this invention is to provide and a kind of can ensureing brake shoe all the time and watt hold in the palm close-fitting railway freight-car brake shoe key.
For achieving the above object, the present invention is by the following technical solutions: a kind of railway freight-car brake shoe key, it is characterized in that: comprise the latch head that a curved latch body and is arranged on described latch body one end, wherein, described latch head and described latch body, in being wholely set and adopting spring steel material to make, arrange one towards the uplift sector of arc lateral direction at the middle part of described latch body.
A through hole passed for confession lock ring is offered at the afterbody of described latch body.
Angle between described latch head and described latch body is 80 ° ~ 90 °
The present invention is owing to taking above technological scheme, it has the following advantages: 1, brake shoe key of the present invention is made owing to adopting Elastic Steel material, and arrange one at the middle part of latch body there is certain flexible backstop, therefore, brake shoe key has pretightening force to a watt nose for brake shoe after assembling, even if operationally stressed part produces distortion, also all can ensure brake shoe and watt close fit of holding in the palm when stressed with when not stressing, can not gap be produced.2, the present invention has through hole at the afterbody of latch body, loads onto lock ring during assembling, can prevent brake shoe key from scurrying out.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is use schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, brake shoe key 1 of the present invention comprises the latch head 12 that a curved latch body 11 and is arranged on latch body 11 one end, and wherein, latch head 12 and latch body 11 are in being wholely set.Brake shoe key 1 of the present invention adopts spring steel material to make, and arranges one at the middle part of latch body 11 towards the uplift sector 111 of arc lateral direction, and uplift sector defines the elastic stop of brake shoe key 1.
In above-described embodiment, the angle between latch head 12 and latch body 11 is 80 ° ~ 90 °.
In above-described embodiment, offer a through hole 112 passed for confession lock ring at the afterbody of latch body 11.
As shown in Figure 2, using process of the present invention is as follows: be connected with brake head 3 by brake shoe 2 with brake shoe key 1 of the present invention, after having connected, the bottom surface of latch head 12 contacts with the end face gusset of brake head 3 head, and watt holding in the palm outside liner plate of the inner side surface of latch head 12 and brake head 3 head contacts.Stop gear in the middle part of brake shoe key 1 is on the outer side surface in brake shoe nostril.The bottom of brake shoe key 1 contacts with the brake shoe liner plate of brake head 3 bottom.Because this brake shoe key 1 have employed elastic material, and devise flexible backstop, pretightening force is there is after assembling in brake shoe key 1 to a watt nose for brake shoe 2, even if operationally stressed part produces distortion, also all can ensure when stressed and do not stress brake shoe and watt close fit of holding in the palm, can not gap be produced.The afterbody of latch body 11 has through hole 112, loads onto lock ring during assembling, prevents brake shoe key 1 from scurrying out.
The present invention is only described with above-described embodiment, and the structure of each parts, setting position and connection thereof all can change to some extent.On the basis of technical solution of the present invention, all improvement of carrying out individual part according to the principle of the invention or equivalents, all should not get rid of outside protection scope of the present invention.
Claims (3)
1. a railway freight-car brake shoe key, it is characterized in that: comprise the latch head that a curved latch body and is arranged on described latch body one end, wherein, described latch head and described latch body, in being wholely set and adopting spring steel material to make, arrange one towards the uplift sector of arc lateral direction at the middle part of described latch body.
2. a kind of railway freight-car brake shoe key as claimed in claim 1, is characterized in that: offer a through hole passed for confession lock ring at the afterbody of described latch body.
