Embodiment 1
[0037] Embodiment 1.1: A material transport vehicle axle gearbox, which includes a box body, and the box body includes a first-stage reduction mechanism composed of two mutually meshing gears I and gear II, and the gear I is sleeved on the running wheel of the material transport vehicle On the axle, the gear II is installed on the intermediate shaft, and the gear III is also set on the intermediate shaft. The gear III meshes with the gear IV. The gear IV is set on the input shaft. The gear III constitutes a two-stage reduction mechanism. Said gear IV is a shift gear, and the gear IV is connected to a shift mechanism, and the end of the shift mechanism includes a gear locking device; the gear speed ratio distribution is: Z I =71, tooth width 115mm; Z II =16, tooth width 119mm; Z III =65, tooth width 60mm; Z IV =18, tooth width 66mm.
[0038] The gear position locking device includes the lower part of the shift fork connected to one end of the gear IV. The upper part of the s...
Embodiment 12
[0043] Embodiment 1.2: a kind of operation method of axle gear box of material transportation vehicle: it comprises
[0044] a. When the system pressure is zero, the shift mechanism of the axle gearbox is always in the disengagement position through the elastic force of the return spring;
[0045] b. When the control system initiates the shifting action, the large chamber of the shift oil cylinder will enter the oil, push the piston rod out, and drive the shifting gear on the fork (that is, gear IV) to mesh with the gear III on the intermediate shaft to carry out shifting;
[0046] c. After the shifting is completed, the large chamber of the shifting oil cylinder maintains pressure to maintain the shifting state.
[0047] d. When the control system initiates a disengagement action, oil enters the small chamber of the shift oil cylinder, pushes the piston rod to retract, and drives the shifting gear (that is, gear IV) on the fork to disengage from the gear III on the intermedia...
