12-speed power high-low gear and power reversing gearbox

Abstract

The invention discloses a 12-speed power high-low gear and power reversing gearbox. The gearbox comprises a power high-low gear transmission device, a power reversing transmission device and a manual gear shifting transmission device, the power high-low gear transmission device is connected with the output end of a tractor engine, the manual gear shifting transmission device is connected with a central transmission mechanism, three power high-low gears can be achieved in the power high-low gear transmission device, one forward gear and one backward gear can be achieved in the power reversing transmission device, four manual gear shifting gears can be achieved in the manual gear shifting transmission device, the gearbox can achieve 24 gears in total including 12 forward gears and 12 backward gears, and partial power is shifted. According to the 12-speed power high-low gear and power reversing gearbox, the structure is simple, clear and compact, the transmission route is clear, the overall space is saved, more gears can be realized, gear shifting and reversing operations can be realized under the condition of not cutting off the power of the engine, the working efficiency is improved, and the working intensity of operators is reduced.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a tractor gearbox, in particular to a 12-speed power high-low gear and power reversing gearbox. Background technique [0002] High-power tractors are increasingly widely used due to their advantages such as high efficiency, economy, and excellent operation. Benefiting from national policies, the demand for high-power power-shift tractors continues to rise. However, at present, my country's research on agricultural equipment is still relatively backward, and the domestic high-power tractor market is occupied by foreign agricultural machinery giants. [0003] The power shift gearbox has the advantages of high transmission efficiency, large transmission torque, low fuel consumption and uninterrupted power during the shifting process. At present, domestic universities, enterprises, and scientific research units are all conducting research on tractor power shift technology. However, compared w...
