Abstract

The invention provides a double-gear transmission case which comprises a transmission gear, a first link gear and a first link gear, wherein the transmission gear comprises a horizontally arranged support shaft, and a first gear shift yoke and a second gear shift yoke which can horizontally slide on the support shaft; the first gear shift device and the second gear shift device respectively comprise input shafts which are arranged symmetrically, and a high-gear gear, a slide toothed sleeve and a low-gear gear which are arranged on the outer side in the radial direction; the top ends of the two input shafts are nearer, and the tail ends are farther; the tail ends and top ends of the two input shafts are respectively provided with a high-gear gear and a low-gear gear; the slide toothed sleeve is connected with the gear-shift yokes and arranged between the high-gear gear and low-gear gear, and can simultaneously make an opposite or reverse slide along the axial direction of the input shafts under the action of the two gear shift yokes; and the two slide toothed sleeves are simultaneously meshed with the two high-gear gears or two low-gear gears, thereby finally implementing the gear shift of the transmission case. The double-gear transmission case provided by the invention has the advantages of simple structure, high use stability and long service life.

Description

technical field [0001] The present invention relates to the technical field of gearboxes, in particular to a two-speed gearbox. Background technique [0002] At present, my country's agriculture is gradually developing towards mechanization, but based on my country's basic national conditions, the design of machinery must be limited to a lower cost. If the gearbox adopts a transmission scheme of hydraulic drive and wheel speed reduction, the cost will increase. Therefore, Most of the gearboxes still adopt the traditional mechanical transmission structure: the engine transmits different powers to the left and right wheels through the meshing of different gears in the transmission structure. [0003] Most of the existing gearboxes are designed with only one shift fork to realize the power transmission of the left and right wheels. Such a structure is relatively complicated and has many parts, which will lead to cumbersome disassembly and assembly process, greater wear and tear ...
