Problems solved by technology

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 transmission system with the main clutch arranged between the main transmission device and the auxiliary transmission device, and having 32 forward gears and 32 reverse gears, so that the gear shifting of the tractor is easier

Abstract

Power reversing tractor drive train with main clutch between main and auxiliary transmissions, including: main transmission, crawler gear, auxiliary transmission, transfer case, oil pump drive, power take-off, constant mesh drive gear, constant mesh Passive gear, PTO rear axle, PTO front axle, oil pump driving driving gear, torsional shock absorber, front output shaft; the main transmission device and the crawling gear device are meshed and connected through the constant meshing driving gear and the constant meshing passive gear, and the crawling gear The device is connected with the auxiliary transmission device, the output shaft in the auxiliary transmission device is connected with the first-stage driving gear of the transfer case, and the first-stage driving gear of the transfer case is meshed with the first-stage passive gear of the transfer case. The driving driving gear and the oil pump driving the passive gear are meshed and connected; a shaft in the main transmission device is connected with the torsional shock absorber, the auxiliary transmission output shaft in the auxiliary transmission device is connected with the rear axle of the tractor, and the transfer case is connected with the front axle 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 a main and auxiliary transmission devices. Background technique [0002] At present, the main clutch is arranged in the front end of the transmission system of various large and medium power tractors produced in China. This arrangement will cause the moment of inertia of the subsequent auxiliary gearbox to increase during the shifting process, and the synchronizer cannot be used for shifting, but the gear shifting can only be done by the meshing sleeve. The shifting time is long and the shifting force is large; therefore, It is necessary to develop a power-reversing tractor transmission system with a main clutch arranged between the main transmission device and the auxiliary transmission device, and with 32 forward gears and 32 reverse gears, so that the tractor can be shifted more easily. Summary of the invention [0003] T...
