A spherical center plate traction device comprises a lower center plate, an upper center plate and a spherical center plate, wherein the lower center plate is fixed with a truck frame; the upper center plate is fixed with a vehicle body II; the spherical center plate is located between the upper center plate and the lower center plate and can rotate between the lower center plate and the upper center plate; the spherical center plate is connected with a vehicle body I; a positioning pin is inserted into center holes of the lower center plate, the spherical center plate and the upper center plate; the positioning pin is locked by a locking pin; the spherical center plate is spherical, elliptic or spindle-shaped; the contact surface between the lower center plate and the spherical center plate is an arc surface which is matched with the spherical center plate; the contact surface between the upper center plate and the spherical center plate is an arc surface which is matched with the spherical center plate. The spherical center plate traction device is mounted on a railway vehicle, so the problem that the vehicle passes the minimum curve radius of a railway is solved.
