Abstract

The invention discloses a speed change mechanism for a tractor. The speed change mechanism is characterized by comprising a shell, an input shaft, an output shaft, a clamp shaft, a gear shifting lever, a clamp assembly and a planet carrier assembly; the input shaft and the output shaft are respectively rotatably connected to the shell, and the input shaft drives the output shaft to rotate; the planet carrier assembly is arranged on the outer side of the input shaft and used for controlling the rotation speed of the input shaft; the clamp shaft is fixed to the shell; the clamp assembly is rotatably connected to the clamp shaft. The speed change mechanism which is simple in structure and stable in gear shifting is provided in order to solve problems of existing gear shifting mechanisms.

Description

technical field

[0001] The invention relates to the field of mechanical transmission, in particular to a speed change mechanism used in tractor transmission. Background technique

[0002] At present, the transmission mechanism widely used in tractors is a mechanical transmission. Generally speaking, this type of transmission can be divided into a two-shaft manual transmission and an intermediate shaft manual transmission. Push the driving gear and the driven gear to mesh to realize gear shifting. However, this type of transmission has some disadvantages: (1) affected by the arrangement of the shift forks, the number of gears is limited; (2) the shifting structure is complicated and the cost is high; (3) the shifting is unstable, and it is easy to skip gears out of gear.

[0003] At the same time, in the shifting structure, in order to reduce the impact of shifting smoothly, the shifting structure is generally equipped with a synchronizer. The widely used synchronizers inc...
