Problems solved by technology

[0002] Rail transit has become the mainstream of transportation in my country. With the rapid development of economy and urban construction in recent years, subways and light rails have been widely used in many cities. However, due to the restrictions of urban development and various specific conditions, subways and light rails The track steering will have a small curvature radius curve phenomenon. The turning radius of the existing vehicle bogies is rigidly connected. The turning radius of this connection method can generally reach 40 meters / R, although it is within the range of the national standard of 100 meters / R , but it is still difficult to meet the needs of the current urban development and reality

Embodiment Construction

[0010] figure 1 As shown: a connecting rod 3 is movably connected between the two frames 1 of the rail car bogie in a cross-diagonal and inclined manner. In the cross-diagonal and inclined mode, one end of the connecting rod 3 is connected to the side beam 2 of one frame 1, and the other end is connected to the side beam 3 on the opposite side of the other frame 1, forming a state of oblique connection. The active connection is a quadrature 4 splice.

Abstract

The invention provides a small-curvature-radius track car bogie frame. A connecting rod is movably connected between two frame bodies of the track car bogie frame in a cross opposite corner and inclined mode. By means of the connection of the structure, the turning radius can be reduced to 19 meter / R when a track car is driven on a track, and the track car can be driven more flexibly and conveniently.

Description

technical field [0001] The invention relates to a rail car bogie, in particular to a small curvature radius rail car bogie. Background technique [0002] Rail transit has become the mainstream of transportation in my country. With the rapid development of economy and urban construction in recent years, subways and light rails have been widely used in many cities. However, due to the restrictions of urban development and various specific conditions, subways and light rails The turning of the track will have a small curvature radius curve phenomenon. The turning radius of the existing vehicle bogies is rigidly connected. The turning radius of this connection method can generally reach 40 meters / R, although it is within the range of the national standard of 100 meters / R , but it is still difficult to meet the needs of the current urban development and reality. Contents of the invention [0003] The invention provides a rail car bogie with a small curvature radius, which can re...
