Tractor speed change device with 16+16 gears

Abstract

The invention discloses a tractor speed change device with 16+16 gears, which comprises a gear shifting unit, a primary auxiliary speed change unit, a main speed change unit and a secondary auxiliary speed change unit, wherein the gear shifting unit, the primary auxiliary speed change unit, the main speed change unit and the secondary auxiliary speed change unit are all arranged in a transmission box, the gear shifting unit is used for realizing advancing or backing of a tractor, the primary auxiliary speed change unit is used for realizing switching between the high gear to the low gear, the main speed change unit is used for realizing switching among four gears, and the secondary auxiliary speed change unit is used for switching between the high gear and the low gear, an output end of the gear shifting unit is connected with an input end of the primary auxiliary speed change unit, an output end of the primary auxiliary speed change unit is connected with an input end of the main speed change unit, an output end of the main speed change unit is connected with an input end of the secondary auxiliary speed change unit. The speed change device is capable of providing 16 advancing gears and 16 backing gears for the tractor and capable of meeting requirements of tractors for various special locality and special operations, and guarantees normal operation of the tractor.

Description

technical field [0001] The invention relates to the technical field of tractors, in particular to a tractor speed change device with 16+16 gears. Background technique [0002] At present, in order to realize the shifting and direction changing functions of tractors, many tractor gearboxes have to set many shifting and direction changing gears in the gearbox box. This leads to too many gears in the gearbox, which makes the gearbox box too large, and the gears provided by the ordinary gearbox cannot fully meet the needs of the tractor in various special conditions and special operations. , which limits the use of the tractor and affects the normal construction work of the tractor, especially the current shifting function of the tractor is mainly based on the forward gear, while the reverse gear is not very perfect, which is very difficult for the tractor in some special conditions. Homework has a greater impact. Contents of the invention [0003] The technical problem to b...
