Abstract
The present invention provides a kind of articulated frame structure for railcar, and vehicle frame is using splited articulated in the structure.The bending of track is adapted to by the relative rotation of seperated vehicle frame when railcar is along track turn.Turning radius can reduce using body frame structure for automotive of the invention, improve passability when railcar turning.
Description
Technical field
The invention belongs to rail transport fields, and in particular to a kind of articulated frame structure for railcar.
Background technique
Railcar is widely used as a kind of transport device.Railcar is frequently necessary to change direction in the process of moving.When
When the wheel base of railcar is larger and axis and vehicle frame are rigidly connected, required turning radius is larger, and passability when turning compared with
Difference.
Summary of the invention
The present invention provides a kind of articulated frame structure for railcar.It can reduce using body frame structure for automotive of the invention
Turning radius improves passability when railcar turning.
The present invention is realized by following methods:
Body frame structure for automotive is divided into multiple portions, such as two parts, which is connected with hinge.When railcar is driven into
When arc track is turned, the vehicle frame two parts being hingedly connected can adapt to the bending of track by relatively rotating, so as to
The turning for realizing small radii is conducive to the raising of passability when railcar turning.
Detailed description of the invention

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
To use the railcar of two body articulated frame structures, for double L-shaped hanger rail traveling.
Fig. 1 show the schematic diagram of four-wheel (two rows of wheels) rigid-frame railcar；Fig. 2 is shown using two body radial types
The schematic diagram of the railcar of body frame structure for automotive, vehicle frame are divided into two parts (21,22), are connected with hinge 3.
Fig. 3 is the case where traveling using the railcar of two body articulated frame structures along straight rail 51,52.
Fig. 4 is minimum turning radius schematic diagram when rigid-frame railcar is turned along arc rail 61,62, and Fig. 5 is then using two
The schematic diagram when railcar of body articulated frame structure is turned along arc rail 61,62 with turning radius shown in Fig. 4.Comparison diagram 4 with
Fig. 5, it can be seen that its turning radius can also be further decreased using the railcar of two body articulated frame structures；Using two
61 outside rib radius R of arc rail is less than arc rail when rigid-frame railcar is turned when the railcar turning of body articulated frame structure
61 outside rib radius R；Normal angle α using the wheel shaft and arc rail 61,62 of the railcar of two body articulated frame structures is small
In the wheel shaft of rigid-frame railcar and the normal angle α of arc rail 61,62, this shows the rail using two body articulated frame structures
Passability when road vehicle is turned is preferable.
It, can also be using the railcar of three-body articulated frame structure (such as Fig. 6 institute with the increasing of railcar wheel base
Show) or the articulated frame structure more than three-body railcar.
Claims (4)
