Wagons frame

Rama is one of the parts of the car body and serves as a basis. On the frame is strengthened automatic coupler device and braking equipment of the car. She herself through pyatniki based on the running gear and treats all types of loads acting on the body. Therefore, the frame shall be of sufficient strength and rigidity to be simple in design, reliable in operation, have a small mass and are available for inspection. In Wagon cars through their pyatniki frame, reinforced by transverse reinforced beams based on glide carts. Connection frame with travel gear ensure pins.

A four-frame consists of a covered wagon sill, the spirit side of the longitudinal beams, two terminal, two pivot, two average cross and two intermediate cross beams. Below each pivot beam located one and two pyatniku skolzuna console of the frame reinforced struts, located between the terminal and the pivot beam, two on each end.

On the side rail on the diagonal to each other, one reinforced footboard. Beam is designed for mounting brake cylinder, and four longitudinal beams are an additional support for the flooring and at the intermediate transverse beams enhance its strength.

Sill consists of two beams Zeta Profile section 310h174h125h11 mm, the distance between the vertical walls of which 350 mm. In the same building cars that distance was 327 mm. The ends of the sill on rivets attached back gauge coupler and teamed with a female front stops.

Lateral longitudinal beams are channel number 20, have a pivot beam box section, and intermediate - U shaped.

The frame consists of a four gondola sill, double pivot, two terminal and four intermediate beams. Sill, like a covered wagon, formed of steel Zeta profile, but on top of the entire length of I-beam welded to it (N 19), to which are attached loop ears manhole covers. Pivot beam more powerful than covered wagons, box section and the ends, except skolzunov have the space for the supporting jacks for podemke cars. Intermediate transverse beam welded sheets of vertical, top and bottom plates. Bottom on all cross members, including pivot and end carriages are installed supports limiting angle hatches in their open position.

Frame six and eight cars on a four-frame design similar to gondola.

However, the beams that make up the frame, more powerful, and the number of intermediate beams in the saints with the length of the frame is also increased in the six-axle gondola up to five, and eight-- up to eight.

A distinctive feature of the four-frame platform is variable section height lateral longitudinal beams. These beams are made of double-T number 55, have a maximum height in the middle, ie where they face the greatest burden. Sill is also made of two I-beams. № 55, connected by ribs. By the end transverse beams to support the flip side socket welded brackets (four to each end beam). Four-frame tank adapted for installation and fixing her boiler. New tank capacity of 60 t are constructed of special sill Zeta rolled number 31 and end cross beams lightweight. Side rails are also lighter only in the area of ​​the pivot to the end transverse beams. Hence the expression - frameless design.

Pivot beam, like all coaches box section, but on top of her attached steel towers, curved form of the boiler tank with the channels, which are placed in oak blocks.

Tanks earlier years of construction were issued with sill welded from two channel number 30, covered the top and bottom plates 8 mm thick. The same sill welded from two channels and pads, and tank capacity of 50 tons, but they have longitudinal side members of channel number 20, the end cross beams U-shaped or L-shaped cross-section, made of stamped sheet thickness of 8 mm , and in between the pivot and the end beams installed by one intermediate cross beam.

Frame-metal passenger car with the floor and the other elements of the body perceives tselnonesuschego acting on the wagon load. On the frame of the car reinforced electrical components and parts brake system, automatic coupler and udarnoupryazhnogo device and buffer. The frame consists of a through the cap, limit, pivot, middle crossbar.

Channels sill connected on 350 mm plates, castings and diaphragm stops absorbing devices or automatic couplers harness devices. Between the sill channel bar on the axes of beams fixed pivot pad. This helps to ensure zhostkost sill channel bars in this section. Pivot transverse beams are welded from sheet and have a box section. They are fixed to the bolt and side cast pyatniki skolzuny. Average transverse beams forged in cross section are shaped bracket. Pivot and secondary transverse beams in the longitudinal direction are shaped beams of equal resistance to bending, ie the length of their height and the greatest change is the connection together with U-section frame of the car. These beams are used to redistribute the loads from the weight of internal and undercar equipment and passengers on the side walls of the body.

Channels end beams are connected by sockets automatic coupling device and the upper and lower plates with ribs.

In operation are all-metal passenger cars, the design of which no middle of the frame. Loads of indoor and outdoor equipment, as well as the passengers perceive the elements in these cars all-metal body. However, this design is unreasonably cars themselves because of the available failure of individual body parts and are not being released.
