Abstract:
The present invention relates to the field of transport mechanical engineering.Object—improve performance and operational reliability of a friction shock absorber.The friction shock absorber (FIG. 2) comprises housing (1), whose walls form orifice (2), and bottom (4) that is in contact with return-and-retaining device (5) contacting a friction assembly that consists of the following elements fitted out with friction surfaces (f1-f10): supporting plate (10), pressure wedge (6), stay wedges (7), and reverse-U-shaped movable plates (9) fitted out with side shelves (14) that cover guide plates (8) and are located on supporting plate (10). Return-and-retaining device (5) is available between the guide plates. Additional return-and-retaining device (11) is available between the pressure wedge and the supporting plate.Recesses for the return-and-retaining device and hard lubricant inserts are available on the guide plates;Movable plates may be partially T-shaped forming side shelves that are located on the supporting plate.Hooks (15, 16) are available on the pressure wedge and stay wedges, located so as to enable a mutual contact during the back stroke of the pressure wedge.
