Abstract

The invention relates to a gearbox, in particular to a power shift gearbox for a wheel excavator. The power shift gearbox for the wheel excavator comprises a gearbox body in which an input shaft and an output shaft are arranged. The power shift gearbox for the wheel excavator is characterized in that the front end of the input shaft is connected with an input flange, the input shaft is sleeved with a low-speed clutch, a high-speed clutch is arranged between the low-speed clutch and the gearbox body in a sleeving mode, a gear ring is arranged between the low-speed clutch and the high-speed clutch, external splines of the input shaft are meshed with three-planet gears installed on one side of a three-planet frame, and external teeth of the three-planet frame are meshed with external teeth of the output shaft. The gear shifting device has the beneficial effects that gear shifting during driving can be achieved, gear shifting is more reliable, and operation is more convenient; and the internal structure is compact, and the space of the whole gearbox is greatly utilized.

Description

(1) Technical field [0001] The invention relates to a gearbox, in particular to a power shift gearbox for a wheeled excavator. (2) Background technology [0002] In recent years, wheeled excavators have become more and more popular among users because of their advantages such as strong mobility and no need for special transportation tools. But at present, the gearboxes of small and medium-sized wheeled excavators mainly use mechanical shift gearboxes, or use imported gearbox assemblies or borrow loader gearboxes. Imported gearboxes are costly and cost-effective; loader gearboxes are large in size and have many gears, and mechanical shifting leads to low efficiency, which cannot meet construction requirements well; ordinary mechanical gearboxes cannot be shifted while driving. It is necessary to stop and cut off the power to shift gears, and the shifting efficiency is low. (3) Contents of the invention [0003] In order to make up for the deficiencies in the prior art, th...
