Abstract

The passenger carriage comprises a housing (1) and a running gear (3) and shock-traction devices fixed to the frame (2).

To increase the manufacturability of the wagon design, reduce costs and reduce the time of its manufacture and repair work, the hull, (1) the wagon is made of two modular parts. The upper blood part (4) is a three-layer monocoque structure assembled from rigidly connected wall three-layer panels (6), ceiling (7) and floor (8), and the lower bottom part (5) is mounted on the frame (2) and provided with containers (9 ) for placement of carriage equipment and laid communications in them (10).

Containers (9) can be sealed and thermostatically controlled, and communications (10) are equipped with interfaces.

Description

The utility model relates to railway transport, and more specifically to the design of long-distance passenger cars.

Modern passenger cars are quite complex material- and energy-intensive vehicles, which create comfortable conditions for passengers to travel.

To ensure these conditions, the design of wagons is complicated and improved, the number of equipment installed on them increases, which naturally leads to an increase in the cost of production of wagons.

In this regard, the search for ways to accelerate and cheapen the manufacture of wagons, their repair and maintenance, to ensure the reliability of the functioning of their systems and assemblies, in particular, by increasing the manufacturability of the design of wagons, becomes very relevant.

A passenger car is already known, containing an all-metal supporting body rigidly fixed to the frame, a running gear, which includes carts with wheelsets, and shock-traction devices [1].

In the manufacture and assembly of a known wagon structure, the base part for body assembly is a frame to which metal

sections of the body, then the body with the frame is mounted on carts with wheelsets and the installation of internal equipment begins.

The known design of a passenger car ensures that the necessary equipment and assemblies are connected inside the hull and in the car space, connected by electric, pneumatic and hydraulic communications laid along the car. However, the process of manufacturing a car, installing its equipment (especially in the car space) and carrying out repair work is complicated, time-consuming and time-consuming.

Also known is a passenger carriage comprising a housing made in the form of a three-layer, monocoque structure, rigidly fixed to a frame with a running gear and shock-pull devices [2].

The design of this famous car has a more technological body, which reduces time and reduces the cost of its manufacture, but slightly reduces the complexity of equipment installation, installation of communications and their replacement and repair.

The technical result that can be obtained by implementing the inventive utility model is to increase the manufacturability of the design of the car, simplify and reduce the cost of installation (dismantling) of its equipment and communication lines, as well as to simplify and reduce the cost of repair work.

To achieve the specified technical result in a passenger carriage comprising a body and a running gear and shock-traction devices fixed on its frame, it is proposed to make the carriage body of two modular

parts: the upper body part, made in the form of a monocock tri-layer structure and the lower one, made in the form of a bottom part fixed to the frame with containers for placing carriage equipment and with communications laid on it, while it is proposed to connect the upper and lower parts to each other using a detachable connection.

For reliable operation of the equipment installed in the lower bottom of the housing, it is also proposed that containers be sealed and thermostatically controlled, and the communications should be equipped with interfaces for connecting to response communications.

The implementation of the claimed utility model is illustrated in the accompanying drawings.

Figure 1 shows a cross section of a passenger car.

Figure 2 shows a cross section of the body part of the housing.

A passenger carriage comprises a housing 1, a frame 2 with a running gear 3 mounted on it and shock-traction devices (not shown in the drawing).

The housing 1 is made in the form of two modular parts - the upper body part 4 and the bottom part 5.

The body part 4 is a monocoque structure of rigidly interconnected trelosny wall panels 6, ceiling panels 7 and floor 8 (figure 2).

The bottom part 5 of the housing 1 is mounted on the frame 2 and is equipped with containers 9 and collectors, channels and / or individual communications 10.

Containers 9 are designed to accommodate various equipment (power sources, motors, generators, units, air conditioners, waste collection tanks, etc.) and are sealed and thermostatically controlled to ensure reliable operation of the equipment located in them.

Almost all the equipment is connected with each other and with the aggregates and systems located in the body part (lighting, heating, sanitary-hygienic, etc.) communications 10 (electric, pneumatic, hydraulic), laid in the bottom part 5 along the compartments 11 allocated to them (and / or collectors, channels, etc.).

Communications 10 can be made with interfaces for connecting with the response communications in the upper body part 4 (not shown in the drawings).

The body part 4 is connected to the bottom part 5 by a detachable connection 12, which can be performed by any of a number of known (using threaded elements, shaped, etc.).

The execution of the housing 1 of two modular parts 4 and 5, significantly different in design, in the composition of the equipment, in the conditions of its operation, allows for their independent assembly, installation of equipment in them, its testing and in their entirety to make their general assembly.

Parallel manufacture and equipment of parts of the housing 4 and 5 allows to reduce the production cycle, creates the necessary conditions for

specialization of workshops (and even factories) reducing the cost of manufacturing cars, and the implementation of the connection 12 detachable simplifies and speeds up the production of repair work.
