FIELD: machine building.
SUBSTANCE: group of inventions relates to machine building. A flexible bush comprises a flexible wall, a ring reinforcing element completely embedded in the flexible wall near an open end, and a holding element. The holding element is installed so that its surface is open along the flexible wall. The outer dimension of the holding element is more than the inner dimension of the ring reinforcing element. A gas spring unit comprises the second end element shifted longitudinally from the first end element. The second end element comprises an end face wall, a side wall and a holding protrusion. The flexible bush is attached between the first and the second end elements. The open end of the flexible bush is inserted along the side wall of the second end element. An assembly method includes the following operations. Installation of the holding element along the open end of the flexible wall. Installation of the flexible wall open end and holding element near the holding protrusion of the end element. Forced movement of the flexible wall open end and holding element along the holding protrusion.
EFFECT: improved reliability of unit performance in tension mode.
