Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coupler transition for an articulated vehicle provided with thermal and noise insulation.

It is known to connect articulated vehicle couplings made of a flexible bellows composed of individual bellows of resilient material. The advantage of these bellows is the possibility of easy replacement of individual parts in case of their damage. The disadvantages of these bellows are high labor, high material costs, insufficient thermal and acoustic insulation, low durability and aesthetic appearance.

Also known are connection junctions of articulated vehicles made of sheet metal side walls of cylindrical shape with a plan view of a circular section.

The advantage of these transitions is low laboriousness, low material costs, higher durability and aesthetic appearance of the sides of the transition, cheap.

Their disadvantage is inadequate thermal and noise isolation. The above mentioned drawbacks are eliminated by the connection transition of the articulated vehicle according to the invention, which consists in the fact that the side walls are also subject to the transition roof having a double wall filled with heat and noise impermeable material. The outer edges of the sidewalls are provided with inner sealing strips which are pressed against the inner sides of the cylindrical walls provided at adjacent ends of the sidewalls of the cell vehicle housing. The cylindrical walls are provided at their outer ends with external sealing strips pressed against the outside of the sidewalls of the transition.

Adjacent semicircular roof ends of the articulated vehicle casing have gutters on the bottom of which are pressed semicircular sealing strips fixed by elastic elements to the circular edge of the transition roof. The spaces between the sidewalls of the transition and the cylindrical walls at the ends of the sidewalls of the cell vehicle housings, bounded by the inner and outer sealing strips, are connected by channels to a cooling air distribution system located below the floor of the cell vehicle housing.

The layers of heat and noise impermeable material located between the walls of the floor, the sidewalls and the roof of the passageway prevent heat and noise transfer to the interior of the connection passage and outward heat transfer.

Sealing strips on the vertical edges of the transition sidewalls and the vertical edges of cylindrical walls at the ends of the sidewalls of the articulated vehicle housings semicircular sealing strips at the edge of the circular transition roof seal the interior of the transition from dust ingress. The heated cooling air supplied by the ducts from the cooling air distribution system to the spaces between the sidewalls and the cylindrical walls at the ends of the sidewalls of the cell vehicle enclosures bounded by the sealing strips creates a thermal screen in these spaces to help heat the interior of the coupling.

An exemplary embodiment of a connection transition according to the invention is shown in the accompanying drawings. Fig. 1 is a cross-sectional view of the junction taken along a vertical plane perpendicular to the longitudinal axis of the vehicle. Fig. 2 is a top view of the junction transition with a partial cross section of the transition roof. FIG. 3 is a cross-sectional side view of the transition from the inside of the vehicle and taken along a vertical plane laid along the longitudinal axis of the articulated vehicle.

The annular floor 1 of the transition, in FIG. 1, consisting of an upper wall 2 and a lower wall J between which a layer 2 of heat and noise-proof material (for example glass fabric) is inserted, is fixed by silentblocks 6 to the cradle 6 of the articulated chassis. vehicles.

ΐ

A cylindrical sidewall 2 of the transition, with a plan view of a circular segment formed from an inner wall, is fastened to the transition floor 1 from both sides. a metal wall 8 and an outer wall 2 between which a glass fabric layer 10 is interposed. By the upper edge, the sidewalls 2 are rigidly connected to a circular roof 11 formed of an upper wall 12 and a lower wall 13 between which a layer 14 of glass fabric is interposed. The annular roof 11 in FIG. 2 is suspended by means of a yoke 15 and two angled rods 16 rotatably mounted on the ends of the yoke 15 and on the brackets 12 located at adjacent ends of the roofs of the articulated vehicle bodies.

* ·

The vertical edges of the sidewalls 2 of the transition are provided with inner sealing strips 18 which abut on the inner side of the cylindrical walls 19 provided at adjacent ends of the sidewalls 20 of the cell vehicle housings.

Similarly, the vertical edges of the cylindrical walls 19 are provided with external sealing strips 21 adjacent to the outside of the sidewalls 2 of the transition. The inner sealing strips 18 and the outer sealing strips 21 seal the space between the sidewall 2 of the transition and the cylindrical shifting 12 'of the articulated body casing, the size of which varies depending on the relative position of the articulated body casing.

Adjacent semicircular ends 22 of the roofs of the articulated vehicle housings, in Fig. 3, are provided with troughs 22, on the bottom of which abut semi-circular sealing strips 21, fastened by means of resilient elements 25. e.g. rubber strips, on the adjacent edge of the circular roof 11 transition.

The spaces between the sidewalls 2 of the transition and the cylindrical walls 19 at the ends of the sidewalls 20 of the cell vehicle housings bounded by the inner sealing strips 18 and the outer sealing strips 21 in Fig. 2 are connected by channels (not shown) to a cooling air distribution system (not shown) cell vehicle cabinets. This ensures the supply of heated cooling air for cooling the electrical equipment of the vehicle to the aforementioned rooms with the function of a thermal curtain.

The connecting junction according to the invention is suitable for rail vehicles and road vehicles.
