The invention relates to a supporting device (1) to vertically support a coupling rod (50) of a coupling (56) pivotably articulated in the vertical direction (V) to a car body underframe (55) by means of a bearing block (51). The supporting device (1) makes contact with the coupling rod (50) by means of a support (2), wherein the supporting device (1) comprises a mount (3) connected to said support (2) which is fixed to the car body underframe (55) of the vehicle. In order to enable the interference-free retraction of the central buffer coupling (56) toward the car body in the event of a crash, the invention proposes that the mount (3) comprise a connecting element (5) by means of which the support (2) is connected to the mount (3) and which defines a rotational axis (R) about which the support (2) can rotate relative the connecting element (5). The invention further proposes the providing of at least one shearing element (6) which connects the connecting element (5) to the support (2) and which is designed to shear off upon the exceeding of a predetermined or definable amount of torque being transmitted from the support (2) to the connecting element (5) via the at least one shearing element (6) in order to allow a rotation of the support (2) relative the connecting element (5).
