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...

Abstract

The invention discloses a material transportation truck axle gear box. The material transportation truck axle gear box comprises a box body, a first-grade speed reducing mechanism is arranged in the box body and comprises a gear I and a gear II which mesh with each other, an axle of a material transportation truck walking wheel is sleeved with the gear I, the gear II is installed on an intermediate shaft, the intermediate shaft is sleeved with a gear III, the gear III meshes with the gear IV, an input shaft is sleeved with the gear IV, the gear III forms a second-grade speed reducing mechanism, the gear IV is a gear shifting gear and is connected with a gear shifting mechanism, and the gear shifting mechanism is connected with a gear position locking device. According to the material transportation truck axle gear box, the space structure is compact, and the axle gear box weight is low and is totally about 500 KG; a welding box body is thin in box wall and good in heat dissipation performance; and the material transportation truck axle gear box can be installed on a same-kind product of which the using strength is lower than a material truck, the self-propelling speed is 0-10 km / hand the coupling running speed is 120 km / h. Gear shifting is conducted by adopting a gear shifting fork and oil cylinder integration mode in the compact internal space, and the space position is exerted to the limit.

Description

technical field [0001] The invention relates to an axle gearbox and belongs to the technical field of design and manufacture of large-scale railway maintenance machinery. Background technique [0002] At present, the axle gearboxes used for loading large-scale road maintenance machinery products are basically purchased or imported except for a small amount of independent products. Not only the cost is high, but also the technology is controlled by others. With the speed increase of trains and the rapid development of high-speed and heavy-haul railways, large-scale track maintenance machinery is playing an increasingly important role in line maintenance. As an important component of the power bogie of large-scale road maintenance machinery, the axle gearbox is used to provide driving force for the self-propelled and working travel of large-scale road maintenance machinery, and to meet the requirements of train linked operation. [0003] As one of the series products of large...
