Title: Link connection between two articulated vehicles
IPC: B61D3/10
Filed: 1992-03-25
Abstract: The two rotary rings (5) of the rotary ring link (4) make possible bending movements between the two vehicles, and elastic parts, pref. rubber components (11), facilitate further movements between them. The one of the two rotary rings is rigidly connected to its corresp. vehicle, while the other is connected to its vehicle via the elastic parts.Forces directed in the vehicle longitudinal direction (3), i.e braking and drive forces, are transmitted between the two vehicles (1, 2) via pressure and tractive activation of the elastic parts, which under the influence of pressure forces are relatively slightly deformable. Bending movements between both vehicles around an axis (9) horizontal in the vehicle cross direction lead to tractive and pressure deformations of elastically deformable components.
