Embodiment

[0024] Such as figure 2 As shown, one includes a shift cylinder group 1, an intermediate shaft 2 and an intermediate gear group 3;

[0025] The piston of the shift cylinder group 1 and the intermediate shaft 2 are integrated. When shifting gears, the piston of the shift cylinder group 1 moves up and down to drive the intermediate shaft 2 and the intermediate gear group 3 to move up and down as a whole to realize gear switching. There is no axial movement between the gear set 3 and the intermediate shaft 2, and there is no wear;

[0026] A bearing 4 is installed between the intermediate shaft 2 and the intermediate gear set 3, and the intermediate gear set 3 is supported on the intermediate shaft 2 through the bearing 4 to realize the rotary motion of the intermediate gear set 3. During the transmission process, only the intermediate gear set 3 rotates , The intermediate shaft 2 only plays a supporting role, and there is no direct wear between them. The lower end of the inte...

Abstract

The invention discloses a gear shifting mechanism of a gearbox. The gear shifting mechanism comprises a gear shifting cylinder group, an intermediate shaft and an intermediate gear group, wherein a piston of the gear shifting cylinder group and the intermediate shaft are combined into an integral body; during gear shifting, the piston of the gear shifting cylinder group moves up and down to drive the intermediate shaft and the intermediate gear group to integratedly move up and down, and gear switching is achieved; the intermediate gear group and the intermediate shaft do not have axial motion, and abrasion is avoided; a bearing is mounted between the intermediate shaft and the intermediate gear group; the intermediate gear group is supported on the intermediate shaft through the bearing, and rotation action of the intermediate gear group is achieved; and during the transmission process, only the intermediate gear group rotates, the intermediate shaft only exerts a supporting function, and direct abrasion between the intermediate gear group and the intermediate shaft is avoided. According to the gear shifting mechanism, the piston of the cylinder group drives the intermediate supporting shaft and the intermediate gear group to integratedly move up and down, gear switching is achieved, the gear group and the intermediate supporting shaft do not have axial motion, abrasion is avoided, the operation state is stable, and the gear shifting mechanism is more suitable for the gear case under the working conditions of a high rotation speed, long-time operation, and frequent gear switching.

Description

technical field [0001] The invention belongs to the field of gear box shift arrangement, and in particular relates to a gear box shift mechanism. Background technique [0002] The traditional gear box shifting mechanism is generally as follows: when shifting, use the fork to drive the intermediate gear set to move up and down on the spline shaft to realize gear shifting. During the transmission process, the spline shaft and the intermediate gear set rotate simultaneously, and the spline shaft moves up and down. Both have bearings to support the spline shaft, specifically as figure 1 shown. [0003] The traditional structure requires the installation of a fork device, the oil cylinder pushes the fork, and the fork pushes the intermediate gear set to move up and down on the intermediate supporting spline shaft to realize gear shifting. This structure occupies a large space. [0004] When the traditional mechanism is driven, the large teeth of the intermediate gear set are co...
