Some non-essential improvements and adjustments made by those skilled in the art in accordance with the above-mentioned contents of the present invention also fall within the scope of protection of the present invention.

[0023] With reference to attached drawings,

[0024] a bogie wheelset radial mechanism with a structure which is of adjustable rigidity is provided, the wheelset radial mechanism 13 is composed of front and rear secondary frames 21 which are pin-connected via two connecting rods 22 arranged in a crosswise manner, the connecting rods 22 are pin-connected to the secondary frames 21 via round pins 24, and joints between the round pins 24 and the connecting rods 22 and/or joints between the round pins and the secondary frames 21 are provided with replaceable elastic materials.

[0025] The joints between the round pins 24 and the connecting rods 22 and/or the joints between the round pins and the secondary frames 21 are provided with rings 23 made of the replaceable elastic materials. Rings 23 made of elastic materials with different rigidities can be mounted according to different requirements of the radial mechanism.

[0026] End portions of the connecting rods 22 are embedded into mounting grooves 25 located in the secondary frames 21 and are pin-connected to same via the round pins 24.

[0027] The end portions of the connecting rods 22 are located on upper mounting planes 31 or lower mounting planes 32 of the secondary frames 21 and are pin-connected to same via the round pins 24.

[0028] A connecting structure according to the present invention is that the end portions of the connecting rods 22 are embedded into the mounting grooves 25 located in the secondary frames 21 and are pin-connected to same via the round pins 24, as shown in FIGS. 3 and 4.

[0029] Another connecting structure according to the present invention is that the end portions of the connecting rods 22 are located on the upper mounting planes 31 or the lower mounting planes 32 of the secondary frames 21 and are pin-connected to same via the round pins 24, as shown in FIGS. 5 and 6.
