Embodiment Construction

[0025] The present invention will be further described below in combination with specific embodiments. The specific embodiments are further explanations of the principles of the present invention and do not limit the present invention in any way. The same or similar technologies as the present invention do not exceed the protection scope of the present invention.

[0026] Combine Figure 1 to Figure 7 .

[0027] Narrow gauge railway vehicle bogie, including wheel set 1, side frame 2, damping device 3, bolster 5 and braking device 6. Wheel set 1 is connected to side frame 2 through rolling bearing device 7 and side frame 2 passes through the center The suspension 4 and the bolster 5 constitute the main structure of the bogie; the double-acting elastic side bearing 8 is placed in the bolster side bearing box, and the bolster side bearing box and the bolster 5 are cast as a whole.

[0028] The double-acting elastic side bearing 8 includes a side bearing device and a roller device; the ...

Abstract

The invention discloses a bogie of narrow gauge railway vehicle, which comprises a wheel pair, a side frame, a vibration absorber, a swing bolster and a braking device. The wheel pair is connected with the side frame in a rolling way through a rolling bearing device; the side frame and the swing bolster form a bogie body structure through central mounting; a dual-acting elastic side bearer is laid in a swing bolster side bearer box; and the swing bolster side bearer box and the swing bolster are cast into a whole body. The invention optimizes structures of the wheel pair, a vehicle axle, the swing bolster and the side frame, and ensures that the wheel pair meets running requirements of narrow gauge (especially 1067mm gauge), and the structural strength of main bearing structures, such as the swing bolster and the side frame, meets bearing requirements of an 18t axle load bogie. The central mounting adopts a dual-stage variable stiffness spring, increases the empty natural bow, and meets different requirements on the central mounting in different operating conditions. By adopting the frictional vibration absorber of the control type bogie, the diamond resistant rigidity of the bogie is improved. By adopting the dual-acting elastic side bearer, stable turning drag torque is provided for the running of a vehicle, and the running speed of the vehicle is increased.

Description

Technical field [0001] The invention belongs to the field of railway vehicle design and manufacture, in particular to the field of railway vehicle bogie design and manufacture, and particularly relates to the design and manufacture of narrow gauge railway vehicle bogies. Background technique [0002] At present, the running parts of railway freight cars in all countries in the world almost all adopt the form of bogies. Usually, each railway freight car usually includes a car body and two bogies supporting the car body. The use of bogie support increases the load, length and volume of railway freight cars and improves the running quality of railway freight cars. Therefore, the performance of the bogie plays a vital role in the load and running speed of the vehicle. [0003] Railways in most countries around the world usually use 1435mm gauge. But some countries also have a considerable number of other gauge railways. For example, the Tanzania-Zambia Railway from Tanzania to Zambi...
