Abstract

The invention relates to a tractor, a transmission system of the tractor comprises a transmission device, a universal driving support, a rear drive axle, a universal transmission rear section and a universal transmission front section, the universal transmission rear section comprises a telescopic transmission shaft and cardan universal joints arranged at the two ends of the telescopic transmission shaft, the cardan universal joints arranged at the two ends of the telescopic transmission shaft are connected with the rear drive axle and the universal driving support, the universal transmissionfront section comprises a telescopic transmission shaft as well as a double constant velocity cardan joint and a cardan universal joint which are separately arranged at the two ends of the telescopictransmission shaft, the double constant velocity cardan joint and the cardan universal joint are separately connected with the output shaft of the transmission device and the universal driving support, a traction shaft is connected with a traction seat through a connecting pin to form a hinged frame, the center of the double constant velocity cardan joint is arranged under the connecting pin, thesteering rotation point of the hinged frame is the midpoint of the double constant velocity cardan joint. In the steering process, power constant angular velocity transmission is realized, that is, the constant velocity transmission can be realized, and the efficiency of the transmission system is effectively improved.

Description

Technical field [0001] The invention belongs to the field of agricultural machinery, and particularly relates to an articulated four-wheel drive tractor. Background technique [0002] Articulated tractors are mainly used for agricultural transportation and / or farmland farming. Due to the use of front-wheel drive, the steering is achieved due to the field deflection hinge point, and the front wheel does not need to be deflected during the front drive. Therefore, the front drive axle has a simple structure and reliable operation, etc. To a wide range of applications. However, because the working conditions of articulated tractors in agricultural transportation and / or farmland operations are very complicated, the use of rear-wheel drive and / or four-wheel drive can further improve the working performance and prevent the vehicle from getting stuck. However, in the process of power transmission to the rear side, because the power transmission route changes during the steering process ...
