Embodiment 1

[0026] Such as figure 1 , figure 2 and image 3 As shown, a double fork shift mechanism of a gearbox in this embodiment includes a differential assembly 1, a fork shaft 4, a fork group 5, an input gear shaft 6, a first gear group, and a second gear group , fork splint 8, gearbox case 10 and fixed sleeve 11, the first gear set is connected with the differential assembly 1 through meshing gears, the first gear set includes driven gear shaft 2, sliding gear 1 in the present embodiment 3 and dual gear 9, above-mentioned sliding gear one 3 is slidably connected to the left end of driven gear shaft 2, and above-mentioned dual gear 9 is matched and connected to the right end of driven gear shaft 2. The second gear set is connected to the input gear shaft 6 connected to the outside of the gearbox case 10. In this embodiment, the second gear set includes a second sliding gear 7, which is slidably connected to the spline shaft. The fork set 5 includes two forks, and the above two fo...

Embodiment 2

[0028] Compared with the embodiment 1, the double fork shift mechanism of the gearbox in this embodiment is different in that the fork shaft 4 is fixedly connected with the fork splint 8 by bolts. The fork group 5 and the fixed sleeve 11 are integrally formed, and are fixed on the left end of the fork shaft 4 by bolts, and bolt fasteners are used, so the fastening effect is good and the connection is stable.

[0029] The double-fork shifting mechanism of the gearbox has the advantages of simple structure, convenient operation, low manufacturing cost, easy maintenance and assembly, and long service life. When shifting gears, the two forks simultaneously drive the sliding gear one 3 and the sliding gear two 7 to move on the first gear set and the second gear set, so that the shifting is quicker and more convenient.

Abstract

The invention discloses a gearbox double-shifting-fork gear shifting mechanism, and belongs to the field of cotton picker transmission systems. The gearbox double-shifting-fork gear shifting mechanism comprises a differential assembly, a shifting fork shaft, a shifting fork set, an input gear shaft, a first gear set, a second gear set, a shifting fork clamping plate, a gearbox body and a fixing sleeve. The first gear set is connected with the differential assembly through a mesh gear, the second gear set is connected with the input gear shaft, the shifting fork set comprises two shifting forks which are connected to the first gear set and the second gear set in a matched mode respectively, the shift forking set and the fixing sleeve are formed in an integrated mode, the shifting fork set is fixed at one end of the shifting fork shaft through a connection piece, and the other end of the shifting fork shaft is connected with the shifting fork clamping plate. The gearbox double-shifting-fork gear shifting mechanism is simple in structure, convenient to operate, easy to assemble, good in gear shifting effect, safe and quick.

Description

technical field [0001] The invention relates to a transmission system, and more specifically relates to a double fork shifting mechanism of a gearbox. Background technique [0002] The range of cotton planting in my country is quite extensive. In the past, cotton picking mainly relied on human hands, which was labor-intensive and inefficient. With the development of agricultural machinery, some cotton pickers have appeared on the market one after another. Electric cotton pickers can effectively increase the speed of manual cotton picking and generate income for cotton pickers. The small cotton picker is a kind of agricultural machinery that is urgently needed in my country's agricultural production, and it is of great significance to the economy of each cotton-producing area. The transmission is a transmission system commonly used in automobiles. The transmission must be equipped with a shifting mechanism to realize the shifting work of the transmission. At present, the tra...
