772,495. Resilient bearings: vehicle suspensions: bogies. SOC. APPLICAZIONI GOMMA ANTIVIBRANTI S. A. G. A. SOC. PER AZIONI. June 21, 1954 [June 19, 1953 ; Oct. 6, 1953], No. 18170/54. Classes 103(6), 108(2) and 108(3). ' Resilient guide means, for the relatively moving parts of a system such as a suspension for an axle bearing or a bogie of a vehicle, comprises resilient rollable elements squashed between guide surfaces on the guiding and guided members, the guide surfaces being parallel to the linear path of relative motion between the members, and the rollable elements being arranged in planes normal to the guide surfaces and being separated from elements in adjacent planes by means of separator elements. Fig. 1 shows an axle suspension in which the guide surfaces are defined by a post 1 working coaxially in a cylinder 2, the rolling elements consisting of annular rubber rings 3 compressed between the post and cylinder. The cylinder 2 may be replaced by a square box with which each ring 3 has four point contact. Furthermore, another cylinder rigid with the post 1 may contain another set of rings 3 that roll on the outside of the cylinder 2. A square post may be used to reciprocate in a square box, the opposed faces of the post and box having separate cylindrical rollers compressed between them. The rings 3, or like elements, are separated by plates 4 having a low coefficient of friction with the rings. Alternatively the rings may be separated by freely rolling balls, or by balls or rollers threaded onto a wire ring, or by a helically wound wire ring. |
