Abstract
The invention is related to transport machine engineering. The objective of the invention is improvement of reliability of a friction shock absorber. The friction shock absorber (Fig. 2) comprises a body (1) with a bottom (4) and with a neck (2) formed by body walls (3) and accommodating a pre-compressed return-retaining device (5) adapted for maximum compression, on top of which a friction assembly (7) is disposed consisting of a pressure wedge (10) and spacer wedges (11) contacting the pressure wedge. The neck of the body houses also guide plates (12) that are in contact with spacer wedges (11) and with movable plates (13) that contact the walls and are provided with projections (21) between which the guide plates are arranged, the latter being mounted on internal projections (26) of the body (1). The opposite sides of the guide plates are provided with friction surfaces (F1 and F2), one of which extends to the length (Lz) from the guide plate ends on the body side toward its neck side, and the other one is below the said length (Lz), the said length (Lz) exceeding one third (1/3 L0) of the guide plates total length (L0). The mutual position of the friction assembly, movable and guiding plates is such that, at maximum compression of its return-retaining device, the length of contacts (Lk) of the spacer wedges with the guide plates to the said length (Lz) is not more than 80 % of the spacer wedge length (M). The friction surfaces (F1 and F2) on the guide plates are fully restricted to the said length (Lz) by hollows (19, 20) in the guide plates along the plane of their friction surfaces (F1 and F2).
