This part is made of current bar profile, which is suitable for the transition between rigid suspension and flexible suspension. Its performance can meet the gradual change of stiffness between riaid and flexible suspension.

The cross section and material of rigid flexible transition body are the same as that of current bar profile, but there are several slots at certain distance of the body, and the depth of each groove gradually increases in one direction, so that the rigidity of the body gradually decreases in one direction, and the flexibility increases gradually, so as to avoid the formation of hard points and the possibility of metal fatigue and fracture when the contact wire enters the rigid system, so as to ensure that When the pantograph passes through the transition interface, it can smoothly and smoothly enter the rigid suspension system from the flexible suspension system, and vice versa.
