The utility model can enable the tractor to satisfy the gears of different engineering operations and has the advantages of simple structure and important application value.
Description
Technical field
The utility model relates to a kind of gear drive, particularly relates to a kind of gearshift mechanism that is arranged in the tractor clutch housing.
Background technique
At present, crawling mechanism is housed in the clutch of the part type of tractor realizes that the operation function of tractor is a kind of very general phenomenon, but the gear box of tractor of this type only is eight advance gear and two to be retreated advance gear and two of gear or six and retreats gear, at some distinguishingly in condition and the special operation, these gears can not satisfy the needs of actual job, limit the use of tractor, also influenced people's construction operation.
Summary of the invention
The technical problems to be solved in the utility model has provided the gearshift mechanism of needed tractor in a kind of operation that can satisfy multiple ground condition and multiple place.
For solving the problems of the technologies described above, the technical solution of the utility model is: the gearshift mechanism of tractor, comprise clutch housing and gear box casing, be arranged on the clutch housing input shaft and stretch into the output shaft that is arranged in the clutch housing on the gear box casing, also be provided with shifting fork assembly in the described clutch housing, also be provided with the regulating mechanism that to select turning to of output shaft or rotating speed by the adjustment of shifting fork assembly down in the described clutch housing.
Described regulating mechanism is for being positioned at the intrinsic engagement toothholder of an end of clutch housing at output shaft, on the engagement toothholder, slide and be provided with the engagement cover, the intrinsic end in end that is positioned at clutch housing on the described input shaft can overlap the driving gear of engagement with engagement, be positioned on the described output shaft clutch housing also rotate be provided with an end can with the driven gear of engagement cover engagement, also be provided with rotating intermediate propeller shaft in the described clutch housing and be fixed with idler shaft, intrinsic driven gear and driving gear on the intermediate propeller shaft, idler shaft is provided with rotating idle gear, described driven gear and driving gear engagement, described idle gear and driving gear and driven gear engagement.
Described gear box casing is provided with supporting base, and described output shaft is by being arranged on the supporting base that two bearings is rotated.
Adopt the gearshift mechanism of the tractor of said structure, by installing and adjusting mechanism in clutch housing, make tractor that the selection of advancing and falling back two kinds of gears arranged, the gear that makes tractor just can carry out reverse gear and forward gears before gearbox is selected, like this, not only can remove the shelves that retreat in the gear box of tractor, reduced the volume of gearbox, retreat shelves or six forward gearss and six and retreat shelves but also make tractor gear become eight forward gearss and eight, the gear of the engineer operation of this kind tractor is increased greatly, satisfied the needs of different engineer operations.By the gear that is provided with on intermediate propeller shaft and the idler shaft with realize cooperating of clutch mechanism moving forward and backward, and be arranged on output shaft on the clutch housing by two bearings and supporting base, not only simple in structure, stable work in work, and long service life.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Accompanying drawing is the structural representation of the gearshift mechanism of a kind of tractor of the present utility model.
Embodiment
With reference to accompanying drawing, the gearshift mechanism of tractor of the present utility model is: comprise clutch housing 8, rotate by bearing respectively and be arranged at input shaft 1 on the clutch housing 8, stretch into the output shaft 2 that is arranged in the clutch housing 8 on the gear box casing 62, also be provided with shifting fork assembly 9 in the clutch housing 8, also be provided with the regulating mechanism that to select turning to of output shaft 2 or rotating speed by the adjustment of shifting fork assembly 9 in the clutch housing 8, this regulating mechanism is for being positioned at the intrinsic engagement toothholder 41 of an end of clutch housing 8 at output shaft 2, on engagement toothholder 41, slide and be provided with engagement cover 42, the intrinsic end of an end that input shaft 1 is positioned at clutch housing 8 can overlap the driving gear 3 of 42 engagements with engagement, the end that output shaft 2 is positioned at clutch housing 8 also is provided with an end can be in the driven gears 7 of engagement cover 42 engagements, also be provided with intermediate propeller shaft 5 in the clutch housing 8 and be fixed with idler shaft 6, intrinsic driven gear 51 and driving gear 52 on the intermediate propeller shaft 5, idler shaft 6 is provided with idle gear 61, driven gear 51 and driving gear 3 engagements, idle gear 61 and driving gear 52 and driven gear 7 engagements.In order to strengthen the stability of output shaft 2, can on gear box casing 62, be provided with supporting base 10, this supporting base 10 can be set to be fixed on a fixed muffle on the gear box casing 62 strengthening the stability that output shaft 2 rotates as much as possible, and 2 of output shafts are by two rotating being arranged on this supporting base 10 of bearing.The working procedure of the gearshift mechanism of this tractor is:
A, as shown in the figure, when engagement cover 42 and driving gear 3 and driven gear 7 all do not mesh, at this moment, driven gear 51 rotations that input shaft 1 drives driving gear 3 and meshes with driving gear 3, drive driving gear 52 by intermediate propeller shaft 5, drive again and the idle gear 61 of driving gear 52 engagements and driven gear 7 idle running of meshing with idle gear 61;
B, as shown in the figure, adjust shifting fork assembly 9, driving engagement cover 42 slides and driving gear 3 engagements, at this moment, input shaft 1 drives driving gear 3 and overlaps 42 with the engagement of its engagement and rotate, thereby drive engagement toothholder 41 and mesh output shaft 2 rotations that toothholder 41 is fixed together, at this moment, be output as forward gears with drive;
C, as shown in the figure, adjust shifting fork assembly 9, driving engagement cover 42 slides and driven gear 7 engagements, at this moment, driven gear 51 rotations that input shaft 1 drives driving gear 3 and meshes with driving gear 3, drive driving gear 52 by intermediate propeller shaft 5, drive again and the idle gear 61 of driving gear 52 engagements and driven gear 7 rotations of meshing with idle gear 61, driven gear 7 drives the engagement cover 42 with its engagement, thereby output shaft 2 backward rotation after passing through the transmission of tertiary gear that drives engagement toothholder 41 and be fixed together with drive engagement toothholder 41, at this moment, be output as and retreat shelves.
The utility model not only makes tractor satisfy the needs of different engineer operations, and simple in structure, long service life, and can be applied among the gear gear of other different power equipment, have important use and be worth.
