Tractor power gear shifting and power reversing transmission device

Abstract

A tractor power gear shifting and power reversing transmission device comprises a power gear shifting module and a power reversing module, wherein the power gear shifting module comprises an input shaft and an output shaft; a plurality of clutches are mounted on the input shaft and the output shaft according to the number of gears; a plurality of meshed gears I are also arranged on the input shaft and the output shaft; the front end of the input shaft is in transmission connection with an engine; the rear end of the input shaft is connected with a tractor PTO device; the power reversing module comprises a reversing shaft and an idler shaft; the reversing shaft is provided with a forward clutch, a backward clutch and a gear II; the gear II is connected with both the forward clutch and the backward clutch; the rear end of the reversing shaft is connected with an auxiliary variable-speed driving shaft of a rear box body of a gearbox; two gears III are fixedly arranged on the idler shaft to form two-stage transmission; the power gear shifting module and the power reversing module are in gear-meshing transmission with each other; and the input shaft, the output shaft, the reversing shaft and the idler shaft are arranged by the adoption of parallel space. The tractor power gear shifting and power reversing transmission device has the advantages that the gear shifting time is short; the number of the gears is large; and the repairing and the maintenance are convenient.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a tractor power shifting and power reversing transmission device. Background technique [0002] At present, the gearboxes of domestic high-power wheeled tractors mostly use mechanical shifting methods such as meshing sleeves and synchronizers. When shifting gears, the tractor needs to separate the dry main clutch first, cut off the engine power, and then shift to the required gear. It is slow, which affects the working efficiency. At the same time, the gear shifting of the meshing sleeve and the synchronizer is all controlled by the shift lever. The operating force is large, the labor intensity of the driver is high, and the shifting work efficiency is low. With the development of domestic power shift tractor technology, in order to improve Working efficiency and improving the comfort of drivers and passengers make it possible for tractors to adopt power shifting and power reversing transmi...

The operating force is large, the labor intensity of the driver is high, and the shifting work efficiency is low. With the development of domestic power shift tractor technology, in order to improve Working efficiency and improving the comfort of drivers and passengers make it possible for tractors to adopt power shifting and power reversing transmission devices

[0003] The current tractor power shift technology is mainly aimed at the full power shift structure. This structure requires high machining accuracy and is difficult to manufacture. It is difficult to meet the needs of domestic manufacturing companies at this stage. Relatively simple structure, reliable and durable high-horsepower power shift tractor transmission
