Power reversing tractor transmission system of main clutch between main speed variator and auxiliary speed variator

Abstract

The invention relates to a power reversing tractor transmission system of a main clutch between a main speed variator and an auxiliary speed variator. The power reversing tractor transmission system comprises a main speed variator, a creeper gear device, an auxiliary speed variator, a transfer case, an oil pump drive device, a power output device, a normally-engaged driving gear, a normally-engaged driven gear, a power output shaft rear shaft, a power output front shaft, an oil pump drive driving gear, a torsion shock absorber and a front output shaft; the main speed variator is connected with the creeper gear device by virtue of the engagement of the normally-engaged driving gear and the normally-engaged drive gear, the creeper gear device is connected with the auxiliary speed variator, an output shaft in the auxiliary speed variator is connected with a primary driving gear of the transfer case, the primary driving gear of the transfer case is engaged with a primary driven gear of the transfer case, and the oil pump drive device is connected with the power output device by virtue of the engagement of the oil pump drive driving gear and the oil pump drive driven gear; a shaft in the main speed variator is connected with the torsion shock absorber, an auxiliary speed change output shaft in the auxiliary speed variator is connected with a rear axle of a tractor, and the transfer case is connected with a front axle of the tractor through the front output shaft.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a power reversing tractor transmission system with a main clutch between main and auxiliary transmission devices. Background technique [0002] At present, in the drive trains of various large and medium power tractors produced in China, the main clutch is arranged at the front end of the drive train. This arrangement will cause the moment of inertia of the auxiliary gearbox at the rear to increase during the shifting process, and the synchronizer cannot be used to shift gears, only the meshing sleeve can be used to shift gears, the shifting time is long and the shifting force is large; therefore, It is necessary to develop a power reversing tractor drive train with the main clutch arranged between the main transmission and the auxiliary transmission, and having 32 forward gears and 32 reverse gears, so as to make the gear shifting of the tractor easier. Contents of the invention ...
