VEHICLE FLOOR SHOCK-ABSORBING DEVICE Russian patent published in 2006 - IPC B61D17/10 F16F15/04 

FIELD: transport engineering.

SUBSTANCE: invention relates to means of protection of operator from harmful action of vibrations and it can be used in cabin of locomotive driver. Floor of passenger vehicle contains skeleton 1 with flooring 2 and shock-absorbing device 4 coupling skeleton with sound-insulating cabin of operator. Shock-absorbing device is coupled with skeleton by means of articulated lever 5 connected with support member of shock-absorbing device containing compression spring interacting with base and swinging suspension made in form of threaded rod connected with spherical plate on one of its ends and threaded bushing, also connected with spherical plate on one of its end non-coupled with threaded rod. Spherical plates interact with at lest three balls of support members of spring and vibration-isolated objected object. Elastomer buffer limiters are placed in base.

EFFECT: improved efficiency of vibration isolation, simplified design.
