[0002] The power output of the hydraulic transmission gearbox in the field of forklift manufacturing is mostly unilateral two-wheel drive output. This type of gearbox can only meet the use of ordinary two-wheel drive forklifts. For off-road forklift gearboxes that require four-wheel drive, it is generally used to restructure The way, function, and performance of tractor and loader gearboxes do not match the requirements of forklifts. However, the existing four-wheel drive off-road forklift gearboxes generally only have a reverse gear setting, and their backward climbing and driving power effects are limited.
[0003] Another example is that the Chinese patent announcement number is CN202021148848.6, a kind of four-wheel drive off-road forklift gearbox, which also has insufficient backward power and has been improved. gear, the forward power range is reduced, and the reverse is increased to a certain extent, the effect is not ideal

The invention discloses a four-wheel drive off-road forklift gearbox with multi-speed backward, comprising a gearbox body, a torque converter is fixed on the upper right wall of the gearbox body, and a turbine shaft of the torque converter is connected to the gearbox body. The first clutch shaft is connected; the gearbox body is hinged with a third-speed clutch shaft, a first clutch shaft, a second clutch shaft, a transmission shaft, a front output shaft, an off-bridge shaft and a rear output shaft; The bearing is hinged with an idler shaft, and an idler gear is fixed on the idler shaft; a third-speed input gear and a reverse gear are installed on the first clutch shaft, and a transmission gear, a first-speed gear and a second-speed gear are installed on the second clutch shaft. There are off-bridge transmission gears and off-bridge gears installed on the axle shaft; it adopts the setting of 3 forward gears and 3 backward gears, which increases the backward power without changing the forward power, makes its backward power sufficient, and improves the backward climbing and backward driving. The power needs, the effect is good.
Description
Technical field: [0001] The invention relates to the technical field of transmissions, in particular to a four-wheel drive off-road forklift transmission with multiple gears in reverse. Background technique: [0002] The power output of the hydraulic transmission gearbox in the field of forklift manufacturing is mostly unilateral two-wheel drive output. This type of gearbox can only meet the use of ordinary two-wheel drive forklifts. For off-road forklift gearboxes that require four-wheel drive, it is generally used to restructure The mode, function, and performance of tractor and loader gearboxes do not match the requirements of forklifts. However, the existing four-wheel drive off-road forklift gearboxes generally only have a reverse gear setting, and their backward climbing and driving power effects are limited. [0003] Another example is that the Chinese patent announcement number is CN202021148848.6, a kind of four-wheel drive off-road forklift gearbox, which also has ...
