Abstract

The invention refers to the transport mechanical engineering, in particular, to tractors transmission reduction gears. The tractor transmission reduction gear comprises a clutch shaft, primary and intermediate gear boxes shafts installed into the clutch bodies and the gear box barrels. On the shafts ends and intermediate shaft barrel there are mounted pinions connected to each other and the clutch shaft is provided with a gear ring and is installed with the possibility of an alternative clutch coupling with the pinion fixed on the shaft thereof, or with the pinion placed on the box gear primary shaft by means of commutation of the tooth-type coupling dislocated on the gear ring and provided with a change-over mechanism. Into the clutch shaft barrel it is mounted an axis on which it is installed an intermediate pinion coupled with the clutch shaft pinion and with the pinion installed on the intermediate shaft barrel of the gear box. The reduction gear is provided with a removable pinions set installed on the clutch shaft, primary shaft and intermediate shaft barrel of the gear box. The technical result consists in rising the general number of the forward and reverse motion gears. Claims: 2 Fig.: 4
