Description

(54) PASSENGER WAGON TRANSITION SITE

one

The device relates to railway transport, in particular to rolling stock, and concerns the design of transitional platforms for passenger cars.

The transitional platform of a passenger car is known, containing a transitional bridge fixed on the end wall, an elastic profile attached along the contour of the platform, horizontal shock absorbers with brushes and vertical oscillation dampers 1.

However, the lack of damping of the relative vertical displacements of the ends of the cars, as studies have shown, leads to a significant deterioration in the smoothness of the car and the increased wear of automatic couplings.

In addition, rigidly coupled frames of the transitional platforms of two adjacent cars with this design have significant vertical displacements relative to the ends of the cars and cause damage to the seals and fences of the transition platform, and also hamper the passage of passengers between the cars.

The purpose of the invention is to increase efficiency by improving smoothness

car and increase passenger safety when moving between cars.

To achieve the goal, the transitional platform is equipped with a ball5 attached to the rod of each shock absorber with one end of the ball5 with a rotatable head in the vertical plane, the other end of which is pivotally attached to the specified vibration damper, and the transition bridge with one end is hingedly mounted on the heads by means of a supporting beam with trunnions, and the other mounted on a cracker, which is mounted by means of a bracket on the end wall of the car.

Each head is made with a wedge

a groove at the end for interacting with the Kli15 with a new protrusion of the head of the adjacent car.

The platform is equipped with lugs mounted on the end wall of the car under the heads for fixing the latter when the connection is broken with vibration dampers.

FIG. Figure 1 shows the transitional plochad, frontal view; in fig. 2 - the same plan view.

In the pockets of the end wall 1 of the car, shock absorbers 2 are mounted, to the rods 3 of which are attached by means of hinges 4:. heads ;; and 5 and 6, one of which is 5 HiCHn with a wedge groove, and the other 6 - with cl ;;: 1spring protrusion.

Gols- 5 and 6 with the help of dampers of verticolpal oscillations 7 and hinges 8 and 9 of the symphony with end wall 1. Transition m {; sik 0 with one end is rigidly connected with the beam beam 11, which with the help of;: .) Jacks 12 and 13 are connected with heads 5 and 6. Moreover, the hinge 13 allows axial displacement and rotation of the support beam relative to the head, and the hinge 12 only rotates about the vertical axis. The other end of the transition bridge rests on a cracker 14 mounted on a bracket 15 attached to the end wall 1 of the car. To close the gap between the transition bridge 10 and the end wall 1 on the last hingedly mounted hinge 16. For sealing the transition platform along its contour is attached an elastic profile 17. On the end wall 1 of the car, under the heads 5 and 6 with a gap, stops 18 are mounted.

Transition site works as follows.

In the uncoupled condition of the cars, heads 5 and 6 are held by oscillation dampers 7 in a horizontal position. When the cars are coupled, heads 5 and 6 come into contact and they are connected by wedge surfaces. If the heights of the coupled cars do not coincide, heads 5 and b will turn in the hinges 4 and will be aligned. The support beams 11 and transitional bridges 10 of two adjacent cars will be in the same plane due to rotation in the hinges 12 and 13.

The elastic profiles 17, when coupling two adjacent wagons, are in elastic contact with each other, ensuring the sealing of the transition platform.

When the cars move as a result of their vibrations, relative displacements of their end walls 1 in the vertical direction occur. In this case, since the heads 5 and 6 are in the coupled state, they are rotated in the hinges 4, as a result of which the oscillation dampers 7 are activated, reducing the oscillations of the cars, both relative and absolute. This improves the vertical smoothness.

travels of cars and wear on automatic couplers. Similarly, the angular oscillations of the cars relative to their longitudinal axis are damped. Transition bridges 10

adjacent cars, regardless of the relative oscillations of the end walls, are in the same plane, which contributes to the improvement of conditions for the transfer of passengers between the cars. In the event of the destruction of one of the vibration dampers 7, the head 5 or 6 turns and rests on the support 18, ensuring the safe passage of passengers between the cars.
