Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting path protector between two vehicles movably connected to each other by a central shock coupler, the connecting path protector having four closed sides. The present invention relates to a straight track having a central portal member that matches the contour of the vehicle, and in which the central portal member is supported so as to be movable in the transverse direction with respect to the vehicle.

A train of the type in which adjacent cars and a connecting road protector are supported on a common central bogie is known from DE 195 1 704 A1. In order to move the inter-vehicle communication passageway laterally with respect to the vehicle, the end of the vehicle has a convex spherical surface in a horizontal plane, and the side of the communication passageway facing this is approximately parallel to the spherical surface of the vehicle. It has a certain concave spherical surface. Therefore, in the upper and lower regions of the connecting channel, the parallel contact surfaces facing each other are vertical, and on their sides the two contact surfaces are inclined in accordance with spherical surfaces. As a result, spherical parallelism is no longer provided when the vehicle is subjected to screw movements, bending movements and rocking movements in opposite directions.

The object of the present invention is to eliminate the above-mentioned drawbacks,
In a train in which each individual car is supported by two bogies, a closed structure is provided between the connecting passage and the cars, which guarantees a constant predetermined distance during all movements and curves. The purpose of the present invention is to provide a communication passage protector.

According to the present invention, this problem is solved by making the contact surface of the vehicle with the central portal member correspond to the surface part of a sphere whose center point is on the longitudinal center axis of the vehicle, and The problem was solved by providing corresponding support surfaces with matched and identical contours.

Next, one embodiment of the present invention will be described in detail with reference to the drawings.

directly on the end face of the vehicle 1 or
An annular contact surface 3 is provided via a web 2 that conforms to the contour shape of. This contact surface 3 is the wheel 1
It overhangs from the end wall 4 of. This contact surface 3 is designed as the surface part of a sphere a whose center point X lies on the longitudinal central axis Y of the vehicle 1 and is consistently inclined with respect to the contour of the vehicle 1. As shown in FIG. 1, the radius of this sphere a is approximately approximately in the range above and below the contact surface 3 with respect to the contour shape of the vehicle 1 whose vertical cross section is larger than its horizontal cross section.
While it is inclined at an angle of 45°, at the curved portions of the ceiling and bottom, and at the sides, the inclination of the contact surface 3 corresponds to the surface of the ball a and differs from this angle even if it is slight. selected.

An annular central gate 5 arranged against the end of the train car has an outer contour adapted to the contour of the car 1 and has a contour shape of the car 1 on the side facing towards the end of the car 1. It has an annular counter-supporting surface 6 which is inclined relative to it. Since the inclination of this corresponding support surface 6 is also matched to the surface of the sphere a, this corresponding support surface 6 and the contact surface 3 form congruent surfaces. The central portal 5 consists of two parts 5a, 5b constructed in the same manner. This part 5a, 5b
are releasably connected to one another and to a horizontally pivotable central shock coupler, not shown, which connects the vehicles 1 to one another and holds them at a distance. Through an opening 8 in the end face of the vehicle 1, which is arranged below the communication channel 7, this central damping coupling, which is also surrounded by the contact surface 3, is pulled out. In this case, the connecting shaft is designed in such a way that the end face of the central damping coupler is located at the separating plane of the parts 5a, 5b. Therefore, when the vehicle is separated from the train, the portion 5a or 5b is separated from the vehicle 1.
can be kept in Due to this configuration and the oblique arrangement of the contact surface 3 and the corresponding support surface 6, the central portal 5 has a supporting and guiding effect in itself, with It is sufficient that only rotation is prevented. Each central damping coupler has a tensioning and pushing device with spring action, as is known, for receiving longitudinal forces. In order to allow this spring movement, the necessary spacing is provided between the vehicle 1 and the central portal 5. The gap created here is covered by an elastic sealing element. The width of the contact surface 3 and the corresponding support surface 6 is determined by the overlapping surface necessary to avoid clearance openings between the wheel 1 and the central portal 5 during curves or other relative movements. be done.
