Autocoupling device

Trailer percussion instruments, which include automatic coupler device, designed for traction rolling stocks and keeping them at a distance from each other, sharing and mitigating actions longitudinal - tensile and compressive forces developing in the train and maneuvering.

Automatic coupler installed on the car (locomotive), automatically mutually engages when pressed or struck and disengaged manually using a lever.

Reduction of longitudinal tensile stress borne coupler to the frame and other parts of the car, provide absorbing devices. In addition to the coupler and absorbing apprata there traction clamp with wedge and supporting bolts and hard plate. Automatic coupler device has also impact socket with centering ravine, and tilting the front stop and the rear stops and support plates.

On a four freight cars set spring-friction draft gear type W-1-TM (Allen first heat treated modernized), and the six and eight carriages W-2-A (hex second termoobrabotany). Absorbing devices such as W-1-TM have limited stroke of 70 mm in the fifth degree. Therefore, the distance from lock coupler to the most salient part of four-socket in cars should be in the range of 60-100 mm. Devices such as W-2 have increased to 110 mm stroke. The distance from the stop to the socket coupler in eight-cars in this connection is established between 100-140 mm.

Recently, four-axle railcar factories equipped cars absorbing devices such as high efficiency III-2-B (Allen second, interchangeable) with a stroke of 90 mm. The gap between the stop and the pin coupler in these cars is 120-150 mm. Shock face outlet made on a spherical, as usual, on the straight. Absorbing devices such as W-2-B on cars with conventional socket set is prohibited.

For the eight-wagons designed spring-friction draft gear W-4-T (Allen fourth, heat-treated), ymeyuschy increased dimensions and hollow stroke is 160 mm.

Tractive with wedge clamp is used to connect to the coupler and draft gear for the transfer of the traction. In the eight-liner trains connect coupler with pulling clamp holds a roller diameter of 90 mm and an aperture of traction clamp for mounting the absorbing device W-2-A, which has several large size of the seat compared with the unit W-1-TM is made increased.

Back gauge are used to transmit the frame of the car compression forces and impacts. Forestay and persistent socket plate transmit power to the frame of the car. Impact socket with a centering device supports and centers the coupler to the longitudinal axis of the rolling stock. At the same time it serves as a safety stop for the coupler body with excessive shock, when fully compressed absorbing devices, and prevents the frame from possible damage.

Centering device in freight cars is centering ravine, hung through two pendulum suspension on impact socket. This device is a centering device Pendulum. With a simple design, this type of device has a significant disadvantage - limited vertical movement coupler at pass hump hump or transitional bridge ferry, resulting in possibly blocked coupler centers and hang one end of the car at the second coupler. Therefore, in the eight-axle cars with increased length of the cantilever frame, set the centering device with a spring-loaded support for the coupler. To organize a two-row spring in the middle of the ravine centering in this case, there is a cylindrical pocket.

Supportive and restrictive trims keep traction clamp with draft gear and thrust plate between the wall sill frame horizontally. There are bars that protect the wall sill wear draft gear and thrust plate during their travels.

Rastsepnoy drive is designed to trip the two automatic coupling without calling mezhvagonnoe man in space, as well as for the installation of the coupler to the off position when pushing cars during maneuvers. It consists of rastsepnogo lever bracket holder and chain.

Coupler centers and retention coupled together is provided by the interaction mechanism located in the pocket of the body coupler.

FSU coaches were equipped automatic coupler SA-W (Soviet automatic coupling, the third option), consisting of a body and mechanism. Details of its mechanism are lock zamkoderzhatel, guard lock, lock and lift the lift shaft. All these parts are cast from steel. Lock is designed to lock coupler centers. With the bottom of the arcuate support surface, lock, rolling on it under its own weight, is in the coupler body down position.

Coupled together in a closed position to comply with automatic coupling and uncoupling and divorced in cars - get ready for bonding.

To monitor the status of the lock it has a signal process. If the lock is recessed into the coupler jaw, the signaling process out through the existing coupler pocket in the bottom of the hole, and if the lock is the down position, the signaling process is not visible and does not act out.

Zamkoderzhatel freely hinged oval overstiem on existing spike inside the coupler from a large tooth. In the disengaged position zamkoderzhatelya paw leaves in mouth coupler, and coupled together is limited to a small neighboring tooth coupler and thus zamkoderzhatel with fuse keeps lock in the down position. In the disengaged position zamkoderzhatel with lift holding lock in the up position until dilution cars. This allows you to push the decoupling, but not divorced cars without restoring the clutch, which is especially useful for shunting operations.

Fuse lock hole hung on his thorn castle and serves to prevent inadvertent release of the coupler with the train.

The lift lock, with two fingers in decoupling wide finger raises fuse with a further turn leads into the lock jaw coupler. After tripping lift, interacting with its narrow finger zamkoderzhatelem holds the lock in the disengaged position to the breeding of cars.

Roller lift is designed to rotate the lift lock in decoupling automatic coupling lever and an exit out of the pocket in the lock jaws collected coupler.

Bolt with a nut and two lock washer roller mounted on the lift dropped when coupler and keep the all the details, the whole mechanism coupler assembled.

In automatic coupling device carriages used by another device absorbs CRI-H6, which provides the necessary fluency in moving trains with seats. It consists of two series are included in the work of the connected parts: spring, friction and spring. Spring-friction part consists of a cap, which has hexagonal inner surface. In the neck are three friction wedge pressure cone. The force of the wedges is transmitted through the washer on the outer and inner spring.

The spring portion has a base, a central spring, the tides in the niche base established small angular spring. Large angular springs placed on the cylindrical neck of the tides in the niches of the spring-friction parts. Small and large angular springs separated thickened part thrust rods, which are inside the arc springs. Both parts of the absorbing unit is bolted to the nut.

But the complexity of the design, the limited energy and lack of stability of friction will require the development of more sovershennyx absorbing devices. One of these devices is rubber used on a small number of passenger cars.

Rubber absorbing device of the type P-2P different spring-friction lower mass and simplicity of design. The case is designed to accommodate nine rubber elastic elements guide plate and pressure plate. Housing and pressure plate alloy steel guide plates of sheet steel. Rubber elastic elements reinforced with steel plates.

To assure continued fit parts to each other in the assembled device comes pre-compressed rubber components by 18 mm. Assembly and disassembly of the absorbing device of the type P-2P are produced with a special device.

A variation absorbing device P-2P is The P-4P with a completely new design elements and rubber rails flat slabs, and therefore simplifies its maintenance.

In passenger wagons have a pilot batch gidrogazovyh absorbing devices, the fundamental difference between them lies in the fact that the load seen by overcoming the resistance of the compressed gas and the hydrodynamic resistance of liquid flowing through kalibrovannye hole from one chamber to another. Retraction apparatus driven by a compressed gas. Gidrogazovy unit is interchangeable with serial absorbing devices for passenger and freight wagons.
