Abstract

The invention relates to a draw gear buffering device for a rail locomotive. The draw gear buffering device comprises a draw gear and a cylindrical gear tail cabinet. A front slave plate is arranged in the gear tail cabinet, the plate face of the front slave plate is perpendicular to the center line of the gear tail cabinet, and the periphery of the front slave plate is fixedly connected with the inner wall of the gear tail cabinet. A back slave plate is arranged at the portion, behind the front slave plate, of an inner cavity of the gear tail cabinet and is parallel to the front slave plate, and the periphery of the back slave plate is fixedly connected with the inner wall of the gear tail cabinet. A buffer is arranged at the portion, between the back slave plate and the front slave plate, of the inner cavity of the gear tail cabinet. Through holes are formed in the portions, corresponding to the front end of the buffer, of the front slave plate and the end face of the gear tail cabinet respectively. The tail of the draw gear penetrates through the through hole in the end face of the gear tail cabinet and the through hole in the front slave plate to be connected with the front end of the buffer. The draw gear buffering device is characterized in that an annular first friction block is arranged on the outer side wall of the buffer, an annular second friction block is arranged at the portion, corresponding to the first friction block, of the inner side wall of the gear tail cabinet, and the first friction block is in contact with the second friction block. The front slave plate and the back slave plate in the buffering device are not prone to damage, and the service life is long.

Description

Rail locomotive coupler and draft gear
Technical field
The present invention relates to a kind of rail locomotive, is rail locomotive coupler and draft gear specifically.
Background technology
At track, motor supply shop is all known in the industry, and coupler and draft gear is mounted in the draw beam of rail locomotive under-carriage structure end, and for transmitting tractive power, braking force also relaxes the vehicle part of longitudinal impact force.
At present, the rail locomotive coupler and draft gear used in industry comprises hitch and columniform hook tail cabinet.From plate before having in described hook tail cabinet, front from the plate face of plate and the central axis of hook tail cabinet, before between the surrounding of plate and the inwall of hook tail cabinet in being fixedly connected with, before have from the hook tail cabinet inner chamber at plate rear after from plate, after parallel from plate with front from plate, and after between the surrounding of plate and the inwall of hook tail cabinet in being fixedly connected with.After from plate and front hook tail cabinet inner chamber between plate, have columniform energy disperser, in arranged concentric between energy disperser and hook tail cabinet, corresponding front in energy disperser front end all has through hole from plate and hook tail cabinet end face, and the afterbody of described hitch is connected with the front end of energy disperser with the through hole hook tail cabinet end face from plate through front.When this coupler and draft gear is subject to longitudinal impact, before only utilizing energy disperser to clash into from plate or after eliminate from plate, the forward and backward impact be subject to from plate is comparatively large, fragile, thus makes the service life of shock absorber shorter.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rail locomotive coupler and draft gear, forward and backward not fragile from plate in this shock absorber, and service life is longer.
For solving the problem, provide following technical scheme:
Rail locomotive coupler and draft gear of the present invention comprises hitch and columniform hook tail cabinet.From plate before having in described hook tail cabinet, front from the plate face of plate and the central axis of hook tail cabinet, before between the surrounding of plate and the inwall of hook tail cabinet in being fixedly connected with, before have from the hook tail cabinet inner chamber at plate rear after from plate, after parallel from plate with front from plate, and after between the surrounding of plate and the inwall of hook tail cabinet in being fixedly connected with.After from plate and front hook tail cabinet inner chamber between plate, have columniform energy disperser, in arranged concentric between energy disperser and hook tail cabinet, corresponding front in energy disperser front end all has through hole from plate and hook tail cabinet end face, and the afterbody of described hitch is connected from the through hole plate with the front end of energy disperser with front through hook tail cabinet end face.The lateral wall being characterized in described energy disperser has the first friction shoe of annular, rub hook tail cabinet madial wall corresponding to block has the second friction shoe of annular with first, the first friction shoe and second rubs and contacts.
Wherein, described first friction shoe and second rubs and makes by rubber, that surperficial indentation that the first friction shoe contacts with the second friction shoe.
Take above scheme, have the following advantages:
Lateral wall due to the energy disperser of rail locomotive coupler and draft gear of the present invention has the first friction shoe, and rub on hook tail cabinet madial wall corresponding to block have the second friction shoe with first, the first friction shoe and second rubs and contacts.When being subject to longitudinal impact, in the process of energy disperser movement forward or backward in hook tail cabinet, the friction force produced between the first friction shoe and the second friction shoe can balance out part of impact force, make energy disperser clash into before from plate or after diminish from impact during plate, make forward and backward not fragile from plate, thus extend the service life of shock absorber.
Accompanying drawing explanation
Fig. 1 is the structural representation of rail locomotive coupler and draft gear of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, rail locomotive coupler and draft gear of the present invention comprises hitch 1 and columniform hook tail cabinet 2.From plate 3 before being provided with in described hook tail cabinet 2, front from the plate face of plate 3 and the central axis of hook tail cabinet 2, before between the surrounding of plate 3 and the inwall of hook tail cabinet 2 in being fixedly connected with, before be provided with from hook tail cabinet 2 inner chamber at plate 3 rear after from plate 4, after parallel from plate 3 with front from plate 4, and after between the surrounding of plate 4 and the inwall of hook tail cabinet 2 in being fixedly connected with.After from plate 4 and front hook tail cabinet 2 inner chamber between plate 3, have columniform energy disperser 5, in arranged concentric between energy disperser 5 and hook tail cabinet 2, corresponding front in energy disperser 5 front end is all processed with through hole from plate 3 and hook tail cabinet 2 end face, and the afterbody of described hitch 1 is connected from the front end of the through hole plate 3 with energy disperser 5 with front through hook tail cabinet 2 end face.The lateral wall of described energy disperser 5 there is the first friction shoe 6 of annular, rub hook tail cabinet 2 madial wall corresponding to block has second friction shoe 7, first friction shoe 6 and second of annular to rub contact with first.Described first friction shoe 6 and second rubs and makes by rubber, that surperficial indentation that the first friction shoe 6 contacts with the second friction shoe 7.
During use, this coupler and draft gear is installed in the draw beam of rail locomotive under-carriage structure end, when being subject to longitudinal impact, in the process of energy disperser 5 movement forward or backward in hook tail cabinet 2, the friction force produced between the first friction shoe 6 and the second friction shoe 7 can balance out part of impact force, before energy disperser 5 is clashed into from plate 3 or after diminish from impact during plate 4, thus make forward and backward not fragile from plate 4, extend the service life of whole shock absorber.
