The device buffers and transition areas

Passengers, baggage, mail, postal and baggage cars and dining cars are heavy and lightweight buffer types and transitional areas of the following types: elastic metal frames with canvas souffle, shock absorbers and buffers, heavy or lightweight, un-buffered elastic metal frames with canvas souffle with shock absorbers; un-buffered with elastic rubber souffle, with buffers and heavy-duty rubber souffle.

All types of transitional areas has hinged apron, located on the front wall of the car, and they are designed to move from one car to another in the parking lot as well as the motion of the train, and to mitigate the shock and impact in moving the train from the place and severe braking on the way.

Elastic gangway with metal frame canvas souffle (harmonics) and shock absorber has a frame, the upper shock absorber in the form of leaf springs attached to the end wall, the transition apron soufflé (harmonic). Souffle in frame rests on top of the spring clip and the bottom is a special pin associated buffers car. Spring lugs attached to the vertical uprights thrust bracket. Planck is located in the same plane with the striking surface buffers.

When coupling cars adjacent elastic platform pressed one against the other top dampers and buffer tarelyami, which provides connections pulling faces after creating a covered walkway to go from car to car.

Transient un-buffered site made the same way. A distinctive feature of these is the fact that the bottom of the frame souffle (harmonics) of the special rack, pins or rivets they are connected with spring tarelyami. Upper shock absorber is designed as a single-row spring.

On most passenger cars the elastic rubber platform souffle, which metal frame and canvas souffle (harmonica) the rubber tube balloon special profile. Transitional area of ​​this type consist of a buffer group, made in the form of conventional standard buffer sets and rubber souffle. Buffer stand for the coupling pin coupler to 65 mm, which provides a selection of clearance and lock automatic couplings by the force generated by compression spring buffer for coupling two cars. On tarelyah buffers with hinges and rivets kranshteynov is a special coal, which is the pillar of the apron area in transition. Convoluted rubber souffle consists of two vertical and one horizontal upper cylinders. Cylinders are rolled into a tube rubber plate thickness of 8-10 mm, which by means of grooved slats are fixed in position. Each cylinder is attached to a rubber souffle racks appropriate profile set on the front wall of cars on the vertical and horizontal on the upper perimeter transition area. At the bottom of the vertical cylinders prescribed additional sealing rubber inserts.

Rubber gangway fitted all types of passenger cars as in the construction and repairs at the factory first and second volumes.

When the cars are connected, folding aprons transitional areas overlap in length, and the head and tail cars are lifted.

When checking the technical condition of transient elastic pads check nodes attaching them to the end wall of the car, • shock absorbers and springs, leaf springs, parts tareley un-buffered transition areas and wear. If tareli have a thickness of less than 5 mm, the standard formulation of repair pads. In this formulation of the double lining is prohibited. Also, check the tightness of the lower shock mount housing, which should be tightened, the presence of crown nuts cotter pins, the nuts are allowed to adjust the height of the setting on her goals to 4 mm thick lower body shock with cracks or break, sagging or kinked spring be replacement. The same applies to the upper spring isolators.

Uprights and the upper horizontal square frame un-buffered transition area with the production of electric welding repair reinforcing plates in the presence of cracks and fractures.

A bent metal frames souffle and elbows attach it to buffers heavy or light type checked by the gap between the lower vertical angle brackets frame elastic platform and operating support planes tareley buffer rods. The gap should be at least 15 mm for cars that do not have the bottom hem frame racks and at least 10 mm in cars with curved struts framework. In a smaller setting allowed tarelyu steel spacer between the buffer rod and bracket bottom gon frame area. The pad is selected depending on the deviation from a controlled gap.

Souffle torn canvas repair patch applied, and worn the metal framework is reduced with subsequent surfacing stripping. Damaged rubber seal metal soufflé to replace, and torn rubber cylinders rubber souffle repaired by stitching or patch formulation. Check the tightness of vertical and horizontal cylinders rubber souffle, loose bolts are not allowed. The weakening of the rivets and bolts brackets and hinges that support angle brackets folding apron eliminated. Mounts checked apron. Straighten bent aprons. Broken or sagging spring hinged pads replaced. Latches and locks folding footpegs sites over US-purpose grease smeared GOST 1033-79 and restore their mobility. Not permitted frames elastic fracture sites, the upper hinge spring, as this can cause them to break in the journey. The renovated room painted.

Buffer passenger cars designed to ensure the smooth progress of cars, divided into heavy and lightweight. Buffer consists of a heavy cast steel buffer cup, which, together with the base of the buffer device is attached to the frame end of the car Four-bedded bolt diameter of 24 mm, buffer cast cylindrical rod with tarelyu, riveted to the flange of the buffer rod rivets. Diameter 500 mm buffer tareley. They have a flat and spherical (convex) surface, the buffer rod with a flat machined tarel Turn installed on the right side when looking at the end wall of the car.

Buffer from one end of the car is compressed to 155 mm, while developing force 60.2 kN (6750 kgf). The reversal of the rod at the expense of small and large springs that are placed in the body buffer device. Spring also absorb shock and impact during the motion of the train. When transferring the force of spring work consistently, while load is transmitted through the flange small spring, and from there through the big curly puck. Buffer glass and its base connected vpotay rivets. A large spring is held in a horizontal position the guide bushing.

Maximum stroke lightweight buffer also is 155 mm. Securing of fall buffer rod glasses by means of the wedge and stem the tide. Buffer glass attached to the pallet with bolts and nuts M20 diameter.

When assembling the local gap between the tray and the buffer glass permitted to 0.75 mm at a depth of 10 mm. The contact surface between the tray and cup before the buffer compound thoroughly cleaned of rust and stained with red lead. Buffer with a glass tray is attached to the frame end of the car Four-bedded diameter bolts and nuts M24. To fix the center of the buffer spring cup on the pallet A connection. Relies on a spring drive with pocket. When working from the terminal buffer force on the spring is transmitted via a disc sleeve. Before assembling the kit buffer space and ground glass rod smeared with grease and spring primed varnish № 177 oil-based. Mating the attachment buffer and frame end-painted. Smooth operation of the buffer set by the inclusion of internal springs.

When checking the technical condition of the buffer check the density of their bolting from the frame end on a pallet. The weakening of the nuts bolts are not allowed. Non-standard and the worn thread bolts and nuts replaced: checks into the buffer, which may change due to failure of internal or external spring. To replace the broken or sagging spring buffer devices disassembled, check the wear of the walls and a glass rod buffer. General deterioration in the form of the gap between the rod and the glass is not allowed bolee10 mm for lightweight and not more than 15 mm for heavy buffers.

Never setting in train and follow them in the presence of coaches: crack, break the buffer rod, glass (regardless of the size and configuration), the bend of the rod (if it does not move freely in the glass); tareley buffer rods same flat form (if one end of the car are both set the bar with a flat base) drawdown springs when the rod buffer passenger car comes in a glass with no spring pressure by more than 25 mm.

The thickness of the adapter un-buffered tareley allow at least 2, and other types of 2 mm: Availability tarelyah pads are relevant drawings or double plates are not allowed.

Omission of these defects in the preparation of passenger trains in flight leads to mutual engagement adjacent cars or to the edge and drop parts on the way while driving.

By following in the train cars with renovated allow tarelyami buffer rods if the rods heavy buffers tareley have a thickness of 20 mm within a circle of 150 mm radius from the center, and in other places is not less than 4 mm with light weight rods tarelyami buffer having a thickness of not 10 mm within a circle of radius of 150 m from the center and not less than 4 mm in the rest, with the difference between the height and the center axis of the lower buffer shocks un-buffered areas of the rail head at one end beams of 15 and 25 mm from the other.

The wagons with trucks CMV height centers buffers regulate staging pads under the bottom bar suspension system beam thickness up to 30 mm, and sealed the bolts, as well as staging a car pyatniki a metal gasket with thickness up to 10 mm. Staging composite gaskets and seals between pyatnikom and glide to ensure safety is not permitted.
