DOUBLE-STEEL-WHEEL ROAD ROLLER AND ITS VARIABLE FREQUENCY VIBRATION CONTROL DEVICE

摘要

A variable frequency vibration control device for a double-steel-wheel road roller comprises a first vibration motor and a second vibration motor in series connected with each other. The first vibration motor and the second vibration motor are respectively in parallel connected to a first shunt branch circuit and a second shunt branch circuit. The flow flowing through the vibration motors can be changed by the shunt branch circuits, and then the vibration frequency of the vibration motors is changed. A double-steel-wheel road roller with the variable frequency vibration control device is also disclosed. The vibration frequency of the vibration motors can be adjusted via the variable frequency vibration control device whenever necessary so as to achieve various operating modes.
