Problems solved by technology

[0002] At present, due to the difference in operating environment and braking conditions between subway tunnel vehicles and railway main line vehicles, there are no engineering vehicles that directly operate in subway tunnels and railway main lines at the same time
Especially for engineering vehicles with relatively large axle load, it cannot meet the requirements of frequent braking and large braking deceleration in subway tunnels, and the braking heat load is high

Embodiment Construction

[0019] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0020] figure 1 Shown is the structural representation of the present invention.

[0021] The present invention comprises a frame composition 1, a wheel set composition 2, an axle box suspension device 3 and a double-base brake device, and the double-base brake device is a disc brake device 4 and a brake shoe brake device 5 .

[0022] Figure 2a Shown is a schematic front view of the structure of the framework of the present invention.

[0023] Figure 2b Shown is a schematic top view of the structure of the framework of the present invention.

[0024] The frame composition 1 is a Japanese-shaped structure composed of side beams 6, cross beams 7 and end beams 8 welded and spliced ​​together. The frame has high strength, eliminates the diamond-shaped deformation of the bogie, has strong diamond-resistant ability, and meets the requirements of st...

Abstract

The invention discloses a novel engineering vehicle bogie which comprises a framework assembly, a wheel set assembly, an axle box suspension device and a foundation brake device. The novel engineering vehicle bogie forms a structure shaped like a Chinese character ri and is high in rhombus resistance. An axle box suspension technology is adopted, unsprung mass is greatly reduced, wheeltrack vertical movement force is reduced, and vertical dynamics performances of a vehicle are improved; the foundation brake device is a dual brake device with a disc-shaped brake device and a brake shoe brake device, and requirements of a heat load during braking of a large axle load and a high deceleration are met; on a railway main line, air pressure is adjusted through a brake valve on the vehicle or the brake shoe brake device is shut down to meet the operation requirements of the railway main line engineering vehicle, and thus barrier-free operation of the engineering vehicle between a subway tunnel and the railway main line is achieved. The novel engineering vehicle bogie is suitable for subway tunnel and railway main line engineering vehicle at a speed of 120 km / h.

Description

technical field [0001] The invention relates to an engineering vehicle bogie, which is suitable for subway tunnels and railway main line engineering vehicles with a speed level of 120km / h. Background technique [0002] At present, due to differences in operating environments and braking conditions between subway tunnel vehicles and railway main line vehicles, there are no engineering vehicles that directly operate in subway tunnels and railway main lines at the same time. Especially for engineering vehicles with relatively large axle loads, they cannot meet the requirements of frequent braking and large braking deceleration in subway tunnels, and the braking heat load is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of engineering vehicle bogie to meet the requirements of vehicle braking and thermal load, and can be applied to engineering vehicles in subway tunnels and main railway lines.
