Connecting assembly and aluminum alloy rail end cover

The utility model relates to the technical field of aluminum alloy rails, in particular to a connecting assembly which comprises an end cover, a fixing support is fixedly connected to the inner end face of the end cover, and a damping synchronizing device is connected to the inner side of the fixing support. The connecting bolt is fixedly connected with a fastening block on the lower end face of a nut; the utility model has the beneficial effects that by arranging the damping synchronizing device, the vibration generated when the track works is slowed down, the vibration with overlarge amplitude is not generated, the end cover and the track are abraded, the vibration frequency of the tracks on the two sides can be synchronized, the distance between the tracks is ensured not to change, and the service life of the track is prolonged. And abrasion of the rail to transported equipment is relieved, and the using safety of the device is improved. 本实用新型涉及铝合金轨道技术领域，具体为，一种连接组件，包括端盖，端盖内端面固定连接有固定支架，固定支架内侧连接有减震同步装置；连接螺栓，
