Abstract

The present invention provides a railway vehicle bogie and a railway vehicle having the same. A bogie for a railway vehicle includes: a first frame body (10) having a right side beam (11); a second frame body (20) having a left side beam (21); and an axle box support device , which has a connecting rod (34A-34D) extending from each axle box (33A-33D). The two frame bodies (10, 20) are combined by means of an elastic element (30). The front right axle box (33A) is supported by the front end (11a) of the first frame (10), and the link (34A) is coupled to the extension (23) extending from the second frame (20). The front left axle box (33B) is supported by the front end (21a) of the second frame (20), and the link (34B) is coupled to the extension (13) extending from the first frame (10). The right rear axle box (33C) is supported by the rear end (11b) of the first frame (10), and the link (34C) is coupled to the side beam (11) of the first frame (10). The left rear axle box (33D) is supported by the rear end (21b) of the second frame (20), and the link (34D) is coupled to the side beam (21) of the second frame (20).

Description

technical field [0001] The present invention relates to a bogie for a railway vehicle, in particular to a bogie capable of realizing self-guiding of front and rear axles and a railway vehicle including the bogie and a vehicle body. Background technique [0002] A rail vehicle consists of a car body and a bogie, which travels on rails. When a railway vehicle passes through a curved road, the force that the wheels press against the track in the left and right directions is generated, which is the so-called lateral pressure. As the lateral pressure increases, the risk of derailment increases, so it is desirable to keep the lateral pressure low. In addition, for the force that the wheels press the track in the vertical direction, that is, the so-called wheel weight, the wheel weight of the wheels on the outer rail side becomes smaller in the section where the track twists, especially in the section where the exit of the curved road eases the curve. When the wheel weight become...
