A connecting device for a cross-connecting rod and a side frame comprises a connecting column (13), a connecting bushing (14), and a bolt (15). The cross-connecting rod (11) is provided with a connecting hole (111). The connecting bushing (14) is mounted in the connecting hole (111) by forming an interference fit and is sleeved on a top end of the connecting column (13). The side frame (12) is provided with a mounting hole (121). A bottom end of the connecting column (13) is mounted in the connecting hole (121) by forming an interference fit. The connecting column (13) is provided with a threaded inner hole (131). A threaded portion of the bolt (15) is connected to the threaded inner hole (131). A head portion of the bolt (15) axially abuts a top end of the connecting bushing (14). The connecting device has a simple and compact structure, is easily mounted or removed, provides a reliable connection, and effectively decreases the total height of the connecting device, such that the connecting device can be arranged in a triangular hole (122) of a side frame (12) of a bogie. The invention simplifies the structure of a bogie and reduces the weight thereof.
