SELF-PROPELLED MACHINE FOR CIVIL CONSTRUCTION AND IN PARTICULAR ROAD MILLING MACHINE, DEVICE FOR RECOVERY OF ROAD SURFACE OR ROAD STABILISER Russian patent published in 2012 - IPC E01C23/88 

FIELD: construction.

SUBSTANCE: invention relates to a self-propelled machine for civil construction, in particular, a road milling machine, a device for road surface recovery or a road stabiliser, which comprise a frame that carriers a chassis unit, a working device for performance of works required for a civil construction operation, in particular, a working drum, and a drive unit installed on a machine frame and controlling a working drum. A power transfer device is used to transfer a moving force from a drive unit to a working device. The drive unit of the self-propelled machine for civil construction comprises the first and second driving motors, a mechanism of power transfer developed in such a manner so that moving forces arriving from the first and second driving motors could be transferred together to the working device.

EFFECT: using motor design in accordance with the invention, a structure is achieved, which especially saves space for a motor, and this makes it possible to increase capacity of a drive unit, without necessity to exceed the specified width for transportation of a self-propelled machine for civil construction.
