Problems solved by technology

For large and heavy-duty tractors, the sliding resistance of the gearbox gears is relatively large, and manual shifting is very difficult; in addition, when the gearbox shifts gears, the cooperation of the clutch is required to change the meshing state of the gears. The existing tractors mainly use conventional gears, The mechanical reversing of the synchronizer or the meshing sleeve adopts flower-type shifting. In order to match the optimal working condition of the tractor, more gears are required, so the gearbox has

Example Embodiment

[0015] Such as figure 1 As shown, the power shift gearbox transmission device of the present invention includes a housing, an input mechanism, a shift mechanism, and an output mechanism installed in the housing, wherein:

[0016] The input mechanism includes an input shaft 1, a left clutch shaft 2 and a right clutch shaft 3 arranged parallel to each other. A first input gear 101 and a second input gear 102 are fixedly mounted on the input shaft 1 and a left clutch shaft 2 is fixedly mounted The left clutch gear 201, the left clutch gear 201 is constantly meshed with the second input gear 102; the right clutch shaft 3 is fixedly mounted with a right clutch gear 301, and the right clutch gear 301 is constantly meshed with the first input gear 101; in this way, The power of the engine can be simultaneously transmitted to the left clutch shaft 2 and the right clutch shaft 3 through the input shaft 1. The positional relationship of input shaft 1, left clutch shaft 2, right clutch shaf...

Abstract

The invention relates to the technical field of tractor manufacturing, in particular to a transmission device of a power shift gearbox. It includes a casing, an input mechanism installed in the casing, a shifting mechanism and an output mechanism, wherein the shifting mechanism includes a left transmission shaft, a right transmission shaft and an output shaft of a power shift section arranged in parallel to each other, and the output mechanism includes a gearbox output Shaft, driven gear for forward gear, driven gear for reverse gear and output synchronizer fitted on the output shaft of the gearbox. The power shift gearbox adopts program-controlled hydraulic and mechanical actuators to complete gear shifting instead of manpower to push the fork lever. The gear shifting operation is convenient, the gears can change a lot, and human misoperation can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of tractor manufacturing, in particular to a transmission device of a power shift gearbox. Background technique [0002] At present, the shifting device of the tractor all adopts the manual shift mechanism that the shift lever directly controls the shift fork to realize the gear meshing. For large and heavy-duty tractors, the sliding resistance of the gearbox gears is relatively large, and manual shifting is very difficult; in addition, when the gearbox shifts gears, the cooperation of the clutch is required to change the meshing state of the gears. The existing tractors mainly use conventional gears, The mechanical reversing of the synchronizer or the meshing sleeve adopts flower shifting. In order to match the optimal working condition of the tractor, more gears are required, so the gearbox has at least one main transmission and multiple auxiliary transmissions. This requires a combination of multiple ope...
