Problems solved by technology

However, the above-mentioned patent still does not consider the spring suspension, so there are still some limitations in improving the diamond resistance and optimizing the low dynamic performance of the bogie, so the performance still cannot meet the requirements, and it is necessary to further improve this

Embodiment Construction

[0017] The accompanying drawing shows an embodiment of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings and the embodiment, but the protection of the present invention is not limited to the content shown in the embodiment.

[0018] As can be seen from the accompanying drawings, the present invention is a railway freight car bogie, which is a low dynamic effect freight car bogie, using a two-series suspension bogie structure, between the side frame and the bearing saddle of a traditional freight car bogie. A suspension system is added in between, and the first suspension system is an axle box spring structure; and a flexible diagonal connection device for the two sides is added on the inner side of the two sides of the first suspension system; A shear spring that is seamless with the side frame and bearing saddle improves the low dynamic performance of the bogie through three links. Among them, the pr...

Abstract

A railway truck bogie comprises the wheel assembly, axle box, bolster, side bracket, bearing saddle on the axle box, side bracket supported on the axle box through bearing saddle, with axle box spring between the bearing saddle top and the side bracket, and shearing spring between the bearing saddle side and the side bracket. The bogie axle box suspension provides vertical and horizontal spring locating rigidity, greatly reducing spring quality, improving vibrating performance of the vehicle, and reducing the action force between wheel track.

Description

technical field [0001] The invention relates to a railway vehicle part, in particular to a structure of a railway freight car bogie part. The international patent classification number is B61F05 / 02, which is mainly used for a new high-speed railway freight car bogie. Background technique [0002] The bogie is the part below the carriage of a railway freight car. Railway freight car bogies are generally divided into primary spring suspension and secondary spring suspension according to the classification of spring suspension devices. Bogies with multiple spring suspensions are rarely used. Because the primary spring suspension bogie has a simple structure, is easy to maintain and manufacture, and has low cost, it is generally used for freight car bogies. In the past, the truck bogies produced in my country were mainly of this type, and this type of bogie could only match the train speed of 50-80 km / h, which was not conducive to the speed-up of trucks; In mixed operation, th...
