Problems solved by technology

[0002] In the common heavy-duty truck gearbox structure, the diameter of the gears on the intermediate shaft of the double intermediate shaft structure range is very different, and its life will be greatly different. Another disadvantage is that the force on the housing generated by the double intermediate shaft structure increases with the The increase of the input torque increases, so for a high-torque gearbox, the possibility of gearbox cracking is high

Embodiment Construction

[0016] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0017] As shown in the attached figure, a gearbox planetary gear train auxiliary case structure, including auxiliary case planetary gear train, auxiliary case synchronizer, auxiliary case planetary gear train 11 adopts helical gears, which improves the bearing capacity of the gearbox and greatly reduces the transmission capacity of the gearbox Assembly noise; the auxiliary case synchronizer 4 is placed before the planetary gear train 11, shortening the length of the output shaft 13 of the planet carrier 14, and reducing the torsional deformation of the output shaft 13 of the planet carrier 14 in the state of high torque; canceling the traditional The ring gear bracket 21 in the structure, the synchronous gear sleeve 5 and the inner ring gear 9 are connected through the torsion spline sleeve 8; the high-grade cone hub 7 is...

Abstract

The invention provides a secondary box structure of a planet wheel system of a speed changing box. According to the technical scheme, the secondary box structure comprises a oblique-tooth planet wheel system of a secondary box and a secondary box synchronizer, wherein the secondary box synchronizer is located in front of the planet wheel system. The secondary box structure of the planet wheel system of the speed changing box has the beneficial effects that the structure is simple and the design is reasonable; the secondary box synchronizer is located in front of the planet wheel system, so that the length of an output shaft of a planet frame is shortened, and the stressing condition of the output shaft is improved; and the planet wheel system adopts oblique teeth to improve the bearing capability of a gear.

Description

technical field [0001] The invention relates to an auxiliary case structure of a gearbox planetary gear train. Background technique [0002] In the common heavy-duty truck gearbox structure, the diameter of the gears on the intermediate shaft of the double intermediate shaft structure range is very different, and its life will be greatly different. Another disadvantage is that the force on the housing generated by the double intermediate shaft structure increases with the The increase of the input torque increases, so for a high-torque gearbox, the possibility of gearbox cracking is high. [0003] The auxiliary box of the planetary structure utilizes the characteristic that the radial force of the planetary structure gear is the internal force, and the force on the casing is very small. extremely high. To sum up, for heavy-duty truck gearboxes with high torque, the planetary gear train for the auxiliary case is a better solution. [0004] The traditional range gear sub-bo...
