Vibratory roller for compactors

Abstract

A vibratory roller for a compactor is provided. The vibratory roller includes a rotary drum, and a vibratory mechanism. The rotary drum includes an inner circumference. The vibratory mechanism is installed within the rotary drum. The vibratory mechanism includes a cradle and at least one actuating cylinder. The cradle is axially suspended within the rotary drum and includes an outer peripheral portion. The outer peripheral portion abuts against a portion of the inner circumference of the rotary drum. The actuating cylinder includes a housing and a piston-rod arrangement. The piston-rod arrangement is slideably positioned relative to the housing and is connected to the cradle. The housing extends and retracts relative to the piston-rod arrangement and a corresponding reaction imparts a vibratory motion in the cradle and the rotary drum.

What is claimed is: 
     
         1 . A vibratory roller for a compactor, the vibratory roller comprising:
 a rotary drum including an inner circumference;   a vibratory mechanism installed within the rotary drum, the vibratory mechanism including:
 a cradle axially suspended within the rotary drum, the cradle including an outer peripheral portion, wherein the outer peripheral portion of the cradle abuts against a portion of the inner circumference of the rotary drum; and 
 at least one actuating cylinder, including:
 a housing; and 
 a piston-rod arrangement slideably positioned relative to the housing and being connected to the cradle, 
 wherein the housing of the at least one actuating cylinder is adapted to extend and retract relative to the piston-rod arrangement and a corresponding reaction imparts a vibratory motion in the cradle and the rotary drum.
