Abstract

The invention relates to a speed reducer for a heavy-duty vehicle. A driving shaft (1) is provided with a driving gear (6), one end of the driving shaft (1) is arranged on a gearbox (4), the other end of the driving shaft (1) is arranged on a gearbox cover (5), a driven shaft (12) is arranged on the gearbox cover (5), a driven gear (2) is arranged on the driven shaft (12) by a fixed plug screw (10) and a conehead screw rod (11), a planetary frame (8) is connected with the driven shaft (12) and provided with a planetary gear shaft (9), a planetary gear (7) is arranged on the planetary gear shaft, the driven gear (2) is meshed with the driving gear (6) and the planetary gear (7) respectively, the gearbox cover (5) is arranged on the gearbox (4), a gear ring (3) is arranged on the gearbox cover (5) and meshed with the planetary gear (7). By adopting the secondary speed reduction mechanism, the speed reducer has large speed reduction ratio, large output torque, and can meet the requirements of multiple operation functions such as bulldozing, hoisting, excavation and the like.

Description

[0001] technical field [0002] The invention relates to a transmission, in particular to a speed reducer for heavy vehicles. Background technique [0003] The function of the gearbox is mainly to reduce the output of the motor and increase the output of the motor. The speed of the engine or diesel engine is generally different from the speed we need, and the output speed is very high. In order to obtain the required speed or torque, the speed of the power source needs to be reduced. [0004] As the last stage reduction device in the drive train, the gearbox is used to further reduce the speed and increase the torque of the output shaft. The original tracked vehicle side reducer adopts the first-stage side reducer, which achieves a relatively small deceleration and cannot meet the requirements of the existing vehicles for bulldozing, lifting, digging and other operating functions such as large torque output. Contents of the invention [0005] The technical problem to...
