Problems solved by technology

However, for the truck bogie with a speed of 200km / h, due to the large difference between empty and heavy trucks, low manufacturing cost requirements, large bogie axle load, simple structure requirements, and convenient maintenance, railway freight cars are used. The design scheme of high-speed passenger cars obviously cannot meet the requirements, and a new design scheme must be adopted to meet the basic requirements of the above-mentioned truck bogies

Embodiment Construction

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

[0020] Such as figure 1 As shown, the 200km / h high-speed railway freight car bogie secondary suspension device of the present invention comprises two secondary rubber springs 1, two secondary lateral stops 2, two secondary vertical stops 3, two secondary Department of transverse oil pressure shock absorber 4, two secondary vertical oil pressure shock absorbers 5, two anti-serpentine shock absorbers 6, four elastic safety chains 7.

[0021] The secondary rubber spring 1 is arranged between the beams 8 on both sides of the frame of the bogie, and is located on the large beam 9 of the frame. A secondary lateral stopper 2 and a secondary vertical stopper 3 are arranged on the outer side of the secondary rubber spring 1, respectively limiting the maximum lateral displacement and roll displacement of the car body relative to the bogie. The secondary vertica...

Abstract

The invention discloses a secondary suspension device for a high-speed railway wagon bogie. The secondary suspension device for the high-speed railway wagon bogie comprises a plurality of secondary rubber springs and is characterized in that the plurality of secondary rubber springs are arranged between two side beams of a framework of the bogie; a plurality of secondary transverse stoppers and secondary vertical stoppers are arranged on the external sides of the secondary rubber springs; a plurality of secondary vertical oil pressure shock absorbers and anti-snake shock absorbers are respectively arranged on the external sides of the secondary vertical stoppers; and a plurality of elastic safety chains are arranged on a framework big cross beam of the bogie. According to the invention, the requirements of maximum shaft weight of 18t and maximum business operation speed of 200 km / h in the wagon can be simultaneously realized; and the secondary suspension device for the high-speed railway wagon bogie, disclosed by the invention, has the obvious advantages of simple structure, reliable performance, low manufacturing cost, greater suitability for empty and load requirements, easiness for passing smaller curves and the like.

Description

technical field [0001] The invention relates to a secondary suspension device of a railway freight car bogie, in particular to a secondary suspension device of a high-speed railway freight car bogie. Background technique [0002] At present, there are generally two types of suspension devices for railway bogies: primary and secondary suspensions. For traditional railway freight car bogies, only primary suspensions or secondary suspensions are generally provided, and primary suspensions are generally not provided for three-dimensional bogies. , and its central suspension is used as its secondary suspension device, which is located between the bolster and the side frame. However, for domestic freight car frame bogies, only one suspension device is provided, and the first suspension device is arranged between the frame and the wheel set. The traditional three-piece bogie and the frame bogie of the freight car adopt the joint bearing mode of the center plate and the side bearin...
