Abstract
A balancing apparatus comprises a rotating shaft (2) arranged on a transition coupler (1), a rotating rod (4) and a top seat (7). The rotating rod (4) comprises an upper and lower end plates (11,12), and a ramp protrusion (13) that is arranged between the upper and lower end plates (12), and is of a sheet protruding structure; when the upper and lower end plates serve as the reference, in the longitudinal direction, the ramp protrusion (13) outward inclines towards the rotating rod, one end of the rotating rod (4) is arranged on the rotating shaft, a pin shaft (5) is arranged at the other end of the rotating rod (4), an eyelet bolt (6) is further arranged on the pin shaft (5), and the rotating rod (4) can rotate around the rotating shaft (2) and hinged to the eyelet bolt (6) through the pin shaft (5). A through hole is formed in the top seat (7), the eyelet bolt (6) penetrates through the through hole in the top seat, a nut (9) is fixedly arranged at the tail end of the eyelet bolt (6), a spring (10) is arranged between the nut (9) and the through hole of the top seat (7), and the diameter of the spring (10) is larger than the diameter of the through hole in the top seat (7). The balancing apparatus prevents a “bent head” phenomenon in a transition coupler when coupling car-couplers.
