Dampening device

Abstract

Dampening device ( 1 ) for a Dozer blade ( 10 ) and related earthwork equipment ( 100 ); the blade ( 10 ) being carried by a frame ( 102 ) of the equipment ( 100 ) through the interposition of an actuating unit ( 106 ) suitable to adjust the vertical position of the blade ( 10 ); an axial-symmetrical member ( 11 ) being carried by the frame ( 102 ) to dampen oscillations associated, in use, to the forward movement of the blade ( 10 ).

1 . A damping device ( 1 ) for a Dozer blade ( 10 ) of an earthwork equipment ( 100 ); said blade ( 10 ) being carried by a frame ( 102 ) of said earthwork equipment ( 100 ) through the interposition of an actuating unit ( 106 ) suitable to adjust the vertical position of said blade ( 10 ); said device further comprising an axial-symmetrical member ( 11 ) carried by said frame ( 102 ) to dampen oscillations associated, in use, with the forward movement of said blade ( 10 ), characterized in that said axial-symmetrical member ( 11 ) comprises a roller ( 11 ′) carried rotatable by said frame ( 102 ) in lowered position so as to discharge to ground, in use, oscillations of said blade ( 10 ) by means of a rolling contact, and in that said roller ( 11 ′) has longitudinal extension similar to an extension of said frame ( 102 ) measured in a direction that is, in use, transverse to the forward direction of said blade ( 10 ). 
     
     
         2 . (canceled) 
     
     
         3 . Device according to  claim 1 , characterized in that said roller ( 11 ′) is carried by said frame ( 102 ) in a freely rotatable manner. 
     
     
         4 . (canceled) 
     
     
         5 . An earthwork equipment ( 100 ) for an excavator comprising a Dozer blade ( 10 ) and provided with a frame ( 102 ) supporting said blade ( 10 ) through the interposition of an actuating unit ( 106 ) suitable to adjust the vertical position of said blade ( 10 ); characterized by comprising a damping device according to  claim 1  with an axial-symmetrical member ( 11 ) carried by said frame ( 102 ) to dampen oscillations associated, in use, with the forward movement of said blade ( 10 ). 
     
     
         6 . (canceled) 
     
     
         7 . Equipment according to  claim 5 , characterized in that said roller ( 11 ′) is carried by said frame ( 102 ) in a freely rotatable manner. 
     
     
         8 . (canceled) 
     
     
         9 . An earthwork equipment ( 100 ) for an excavator comprising a Dozer blade ( 10 ) and provided with a frame ( 102 ) supporting said blade ( 10 ) through the interposition of an actuating unit ( 106 ) suitable to adjust the vertical position of said blade ( 10 ); characterized by comprising a damping device according to  claim 3  with an axial-symmetrical member ( 11 ) carried by said frame ( 102 ) to dampen oscillations associated, in use, with the forward movement of said blade ( 10 ).
