Problems solved by technology

In many foreign countries with narrow gauge railway lines, narrow gauge bogies have been widely used, but the speed of passenger cars in some African countries is between 40-50km / h, and the performance is poor, even in some developed countries, such as Japan , the speed of narrow-gauge railway passenger cars is only 120km / h

Embodiment 1

[0037] Such as Figure 1 to Figure 3 As shown, a narrow-gauge passenger car EMU bogie is used for narrow-gauge EMUs, and is suitable for 1067mm narrow-gauge EMUs. It includes a frame on which two wheelsets, a traction device, a traction motor 5, a gear box 6, a primary suspension device, a secondary suspension device and a foundation braking device are arranged. The wheelset is fixed on the frame through the primary suspension device, and the frame is connected with the vehicle body through the secondary suspension device. The primary suspension device includes a pivoting arm type axle box 12, steel spring 13 and vertical shock absorber 15, the secondary suspension device includes an air spring 7, an anti-roll torsion bar 8 and a height adjustment valve 9, and the wheel set includes wheels 10 and Axle 11.

[0038] Such as Figure 4 to Figure 6 As shown, the frame is composed of two side beams 1, two beams 2, and two end beams 3, the two ends of the two side beams 1 are conn...

Embodiment 2

[0072] Such as Figure 12 As shown, this embodiment provides a narrow-gauge passenger car trailer bogie.

[0073] The difference from Embodiment 1 is that there is no need to weld the traction motor mounting base 36 and the gear box suspender seat 38 on the sides of the two beams 2 of the frame, that is, there is no need to install the traction motor 5 and the gear box 6, only need to weld and fix The traction rod seat 37 and the integral lifting seat 39 are integrated in the installation suspension seat 35 in an integrated structure.

[0074] Through the improvement of the above internal structure, the matching combination of various components and the optimization of performance parameters, the performance of the whole bogie is obviously improved, so as to meet the design requirements. It is suitable for 1067mm narrow gauge railway, and the speed can reach 160km / h. Good stability, safety and comfort.

Abstract

The invention relates to a narrow-gauge train bogie which comprises a framework. Two wheel sets, a traction device, two traction motors, two gearboxes, a primary suspension device, a secondary suspension device and a foundation brake device are arranged on the framework. The primary suspension device is composed of a steel spring and a rocker arm type axle box, the rocker arm type axle box is connected with the framework through the steel spring, each wheel set comprises a wheel axle and wheels fixed to the two ends of the wheel axle, the wheel axles are connected with the rocker arm type axle box, the secondary suspension device comprises an air spring, a side rolling resisting torsion bar and a height control valve, the air spring, the side rolling resisting torsion bar and the height control valve are arranged on the framework, and the foundation brake device is a wheel-mounted disc brake device. The components are optimized and are combined in a matched mode, performance parameters are optimized, and therefore the performance of the bogie is greatly improved. As is proved by the experiment, according to the narrow-gauge train bogie, the operating speed of a train can be 160km / h on a narrow gauge of 1076mm, and the narrow-gauge train bogie has good stability, comfort and safety performance.

Description

technical field [0001] The invention relates to a bogie, in particular to a narrow-gauge passenger car bogie. Background technique [0002] Narrow gauge refers to the track whose gauge is less than 1435mm standard gauge, and the width of most narrow gauge tracks is 1067mm or 762mm. There is no narrow-gauge railway line in mainland my country. There was a line with a gauge of 1000mm in Kunming, but the speed of passenger cars was between 20-40km / h. In many foreign countries with narrow gauge railway lines, narrow gauge bogies have been widely used, but the speed of passenger cars in some African countries is between 40-50km / h, and the performance is poor, even in some developed countries, such as Japan , the speed of narrow-gauge railway passenger cars is only 120km / h. Contents of the invention [0003] The main purpose of the present invention is to solve the above problems and deficiencies, and provide a narrow-gauge passenger car bogie with a speed up to 160 km / h, whic...
