Problems solved by technology

Due to the use of the meshing sleeve mechanism for shifting, the shifting of the meshing sleeve is easy to cause impact on the shifting elements during the shifting process, which will accelerate the damage to the end faces of the shifting teeth and the shifting process will be unstable, which will affect the life of the gears.

Embodiment Construction

[0014] Such as figure 1 As shown, a 10+10-gear gearbox is used on tractors or other similar motor vehicles. It realizes 10 forward gears and 10 gears through sequentially arranged main transmission mechanism, high-low gear transmission mechanism and front and rear gear transmission mechanism. a reverse gear.

[0015] The main structure of the main transmission mechanism is as follows:

[0016] The first shaft 1 is rotatably mounted on the box body of the gearbox through bearings. The constant meshing driving gear 2 is fixedly installed on the first shaft 1. One end of the first shaft 1 is the power input end, and the other end of the synchronizer connection end is provided with 4th and 5th gear synchronizer 3 Coordinated external teeth.

[0017] The second shaft 12 is arranged coaxially with the first shaft 1, and one end of the second shaft 12 is mounted on the synchronizer connection end of the first shaft 1 through bearing rotation, and the other end is mounted on the cas...

Abstract

The invention discloses a gearbox with 10 forward gears and 10 reversing gears. The gearbox comprises a main speed change mechanism with five gears, a high-to-low gear speed change mechanism and a front-to-back gear speed change mechanism. Synchronizers are adopted for gear shifting in the main speed change mechanism. In the gear shifting process, the rotation speeds of two parts to be hitched are consistent and synchronous through the effect of the friction force, gear-shifting elements become meshed without impact, the synchronizers make gear shifting easy, the end surfaces of gear-shifting teeth are protected against damage, and therefore the service life of the gear-shifting mechanisms is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a 10+10 gear gearbox for tractors or corresponding motor vehicles. Background technique [0002] At present, the main transmission of 55-80 horsepower tractors provides 4 gears, and the auxiliary transmission provides two gears, realizing 8 (forward gears) + 8 (reverse gears) gears. Due to the use of the meshing sleeve mechanism for gear shifting, the gear shifting of the meshing sleeve is likely to cause impact on the shifting elements during the shifting process, which will accelerate the damage of the end faces of the shifting teeth and the shifting process will be unstable, which will affect the life of the gears. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a 10+10 gear transmission to reduce the impact on the shifting elements during the shifting process and has a compact structure. [0004] In order to so...
