Tractor part power shift transmission

Abstract

The invention relates to the field of a tractor and discloses a partial power shifting transmission device for the tractor. The partial power shifting transmission device for the tractor comprises a power shifting part (1), an ordinary creeper gear shifting part (2) and a synchronizer shifting part (3), wherein a shaft I (S1), a shaft II (S2) and a reverse gear shaft (S3) are mounted inside the power shifting part (1); a shaft IV (S4) and a shaft V (S5) are mounted inside the synchronizer shifting part (3); one end of the shaft I (S1) is connected with an engine, and the other end of the shaft I (S1) is connected with a hydraulic control mechanism (36); one end of the shaft V (S5) is connected with a rear axle, and the other end of the shaft V (S5) optionally outputs power to a front axle; the shaft IV (S4) and the shaft II (S2) are coaxially arranged, and are connected with each other through the ordinary creeper gear shifting part (2). With the adoption of the partial power shifting transmission device for the tractor, the gear number is increased while partial power shifting is realized, so that the transmission efficiency of the entire transmission device is improved, and the manufacture cost is reduced.

Description

technical field [0001] The invention relates to the field of tractors, in particular to a tractor partial power shift transmission device. Background technique [0002] The gearboxes of tractors are mostly sliding gear shifting and meshing sleeve shifting, and the shifting process often needs to go through the neutral position, which causes the interruption of power transmission. If the tractor is working at low speed and high traction, interrupting the power transmission means stopping and restarting the tractor, which will affect the production efficiency of the unit. In the past two years, some companies have developed synchronizer shifting and matching operating systems, but this shifting method has a large range of gears and speeds, complex operations, unsmooth shifting, and cannot achieve stability under load. Shifting gears cannot meet the agronomic requirements of precision agriculture and intensive cultivation. [0003] The tractor rear axle is composed of a centr...
