Title
(EN) DEVICE FOR CUTTING ASPHALT
(FR) DISPOSITIF DE COUPE D'ASPHALTE
Abstract
(EN)
The present invention relates to a device for cutting asphalt. The device is connectable to a construction vehicle, such as an excavator, and comprises a circular cutting disk having a central axis, about which axis the cutting disk is rotatable. The device further comprises an actuator having an axis of rotation, parallel to the central axis of the circular cutting disk, and an eccentric element arranged along the axis of rotation of the actuator. The eccentric element is rotatable about the axis of rotation, independently of the circular cutting disk. The actuator is connected to the eccentric element and arranged to rotate the eccentric element about the axis of rotation, wherein the rotation of the eccentric element causes the cutting disk to oscillate radially to the axis of rotation. The oscillation of the cutting disk enhances the cutting efficiency of the device, and makes it less dependent on the weight of the construction vehicle.

La présente invention concerne un dispositif de coupe d'asphalte. Le dispositif peut être relié à un véhicule de construction, tel qu'une excavatrice, et comprend un disque de coupe circulaire ayant un axe central, autour duquel le disque de coupe peut tourner. Le dispositif comprend en outre un actionneur ayant un axe de rotation, parallèle à l'axe central du disque de coupe circulaire, et un élément excentrique disposé le long de l'axe de rotation de l'actionneur. L'élément excentrique peut tourner autour de l'axe de rotation, indépendamment du disque de coupe circulaire. L'actionneur est relié à l'élément excentrique et agencé pour mettre en rotation l'élément excentrique autour de l'axe de rotation, la rotation de l'élément excentrique amenant le disque de coupe à osciller radialement par rapport à l'axe de rotation. L'oscillation du disque de coupe améliore l'efficacité de coupe du dispositif et le rend moins dépendant du poids du véhicule de construction.
