multipurpose gearbox

Abstract

The invention discloses a multipurpose gearbox which comprises a main speed change mechanism. A power output mechanism is in driving connection with an output end of the main speed change mechanism and an input speed change mechanism is in driving connection with an input end of the main speed change mechanism. According to the technical scheme adopted by the invention, the traditional main speed change mechanism with eight forward gears and two back gears is integrated with the input speed change mechanism and the power output mechanism in the same gearbox, so that a transfer case is omitted and the structure of the gearbox is simpler; inputting two different speeds to the main speed change mechanism is realized through the input speed change mechanism, so that the gears of the gearbox are widened, the gearbox is provided with sixteen forward gears and four back gears, the speed change mechanism does not become complex and the shell of the gearbox does not become huge; the rear-wheel driving or four-wheel driving is realized by the power output mechanism, so that the engineering operation scope of a tractor is greatly widened and the tractor can adapt to the engineering operation under different floor conditions.

Description

technical field [0001] The invention relates to a variable speed transmission mechanism for a tractor, in particular to a multipurpose gearbox. Background technique [0002] At present, tractor transport machinery realizes the conversion between different speeds through the gearbox. Tractors and transport machinery have to add a transfer case in order to realize the speed change and direction change functions. This requires setting many gears and gears in the gearbox housing. The combination of speed change and direction change gears makes the speed change mechanism too complicated and the gearbox too large. The existing gearbox has eight forward gears and two reverse gears. The needs of the industry limit the use of tractors and affect people's construction operations. In addition, most of the existing tractors use rear drive. When the tractor is loaded, it is prone to slipping due to insufficient power, which will affect the construction work.
