| 摘要 |
The invention refers to the transport machine engineering, namely, to the tractor transmission reduction gears. The tractor transmission reduction gear contains clutch shaft, primary and intermediate transmission shafts, installed into the barrels of clutch bodies and transmission, as well as pinions mounted on the shafts ends, on the intermediate shaft barrel and coupled one to another. The clutch shaft is provided with a gear ring and is installed with the possibility of alternative coupling of the clutch to the pinion, situated on the primary transmission change shaft by means of changing-over gear-type coupling. Such gear-type coupling is in engagement with the gear ring of the gear-type coupling shaft.The tractor reduction gear is additionally provided with an intermediate pinion, coupled to the gear-type coupling pinion and to the two-corona pinion.The result consists in rising the total number of the tractor forward and reverse movement gearing.Claims: 2Fig.: 4
