Abstract
The utility model relates to transmission gears, in particular to a tractor transmission gear, which comprises a body and a transmission shaft mounted inside the body. A transmission gear is arranged on the transmission shaft and includes a first shaft, a second shaft and a reversing shaft. The tractor transmission gear is technically transformed and improved on the basis of a TS250 series (25-40 horsepower) tractor transmission gear currently produced by Shan Tuo agricultural machinery and equipment limited company and is excellent in technical inheritance. Gears of a tractor are increased so that ten forward gears and two reversing gears can be realized for high and low speed shifting. Speed range of the tractor is increased so as to range from 2Km/h to 36Km/h, and accordingly a user can select an ideal working gear according to operation need. Rotation speed of a reversing idle wheel is only about 20% of that of an idle wheel in an original-structured transmission gear by the aid of a front-mounted structure of a reversing gear of the tractor transmission gear. Meshed sleeve structures are adopted for shifting, and accordingly, shifting is light and convenient, service lives of gears are prolonged, and noise of the tractor transmission gear is greatly reduced.
