Embodiment Construction

[0019] Such as image 3 The shown low-floor rail vehicle, in particular a tram, is arranged in a two-car configuration with sections A and B and three bogies.

[0020] Figure 4 The vehicle in is extended by a section and has four bogies.

[0021] shown in image 3 The articulated rail vehicle in is equipped with a first end rotatable bogie 1 under the front of section A and a second end bogie 1 under the rear of section B and at the hinge ( An intermediate bogie 2 under the link between sections A and B of the vehicle, while both adjacent ends of the body (sections A and B of the vehicle) are rotatably mounted on the intermediate bogie , each located in separate mounting points 3.

[0022] The position of the bogie is shown in the Figure 8 and Figure 9 middle. The bogies 1 and 2 are arranged in such a position that the elements of the primary and secondary elastic means 5 are located in the spaces between the pairs of separately mounted wheels of the bogies and that ...

Abstract

The invention relates to a special low-floor hinging type rail vehicle for a railroad car. The special low-floor hinging type rail vehicle is in a structure that two compartments and three steering frames are arranged or at least one middle compartment and a middle steering frame are arranged in an extending manner. The special low-floor hinging type rail vehicle is characterized in that for the vehicle, rotatable end part steering frames (1) are always arranged below the front part and the rear part of the vehicle, and middle steering frames (2) are always arranged below each joint respectively; the joints are connecting parts between every two part segments of the vehicle; besides, two adjacent vehicle bodies of the vehicle are mounted on each middle steering frame(2) in a rotatable manner, each of the vehicle bodies is positioned in respective attachment points (3) , elements of primary and secondary elastic devices (5) are positioned in spaces between pairs of independent mounted wheels, and in particular, a motor, a gear case, a disk-shaped brake and a driver and a brake (6) of a track brake are positioned on the outer sides, which are opposite to the longitudinal axis of the vehicle, of the wheels, so that even a motherboard is on the steering frames, the motherboard is also at a low-standard level.

Description

technical field [0001] The invention relates to an arrangement of low-floor trams for passenger transport, especially designed for municipal traffic. Background technique [0002] Low-floor trams are manufactured to have a low floor over the entire length of the vehicle, while the height of this floor above the top of the track in the range of 350÷450 mm may be considered standard and a minimum standard passing width of 600 mm . In order to keep the floor height at this standard level, the bogies of these trams are usually equipped with broken axle beams with independently mounted pairs of wheels with a common geometrical axis of rotation. These axle beams with independently mounted wheels replace standard wheel sets (ie pairs of wheels pressed on a common axle) and are able to pass through the floor at low floor level, even between the wheels. [0003] However, in the case of using a rotatable bogie, when it rotates toward the vehicle body around the vehicle axis, the whe...
