Abstract
The utility model discloses a change speed gearbox, which comprises a spline shaft, sliding gears and a shifting fork. At least two sliding gears are disposed on the spline shaft, a shifting fork shaft sleeve is disposed between the adjacent sliding gears, both ends of the shifting fork shaft sleeve are provided with a connecting plate connected with the sliding gears, and a convex plate engaged with the shifting fork is further disposed on the shifting fork shaft sleeve. The change speed gearbox has the advantage that engagement of the sliding gears can be controlled only by using the shifting fork to shift the convex plate, thereby reducing design difficulty and lowering manufacturing cost.
Description
Technical field
The utility model relates to a kind of speed-change gear box.
Background technique
Existing speed-change gear box is to utilize shift fork to regulate the purpose that different gears on the splined shaft and the gear matched on the upper level axle reach speed governing, but at least two shifting slide gears are arranged generally on the spline, if shift fork contacts adjusting then has increased design difficulty with each gear, shifting slide gear is all made gear train has then increased manufacture difficulty and cost, and also inconvenience replacing when damaging appears in one of them gear.
The model utility content
The purpose of this utility model is to provide a kind of speed-change gear box, can effectively solve the problem that shift fork is regulated shifting slide gear inconvenience in the existing speed-change gear box.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of speed-change gear box, comprise splined shaft, shifting slide gear and shift fork, described shifting slide gear has at least two, described shifting slide gear is arranged on the splined shaft, is provided with the shift fork axle sleeve between the described adjacent shifting slide gear, and described shift fork axle sleeve two ends are equipped with land, described land links to each other with shifting slide gear, and described declutch shift shaft puts and also is provided with the protruding dish that matches with shift fork.
Preferably, described protruding dish and a land are for being wholely set; The convenient manufacturing increases global reliability.
Preferably, adopt bolt to be connected between described land and the shifting slide gear; Change easy accessibility.
Compared with prior art, the utility model has the advantages that: only need utilize shift fork to stir the cooperation that protruding dish just can be controlled whole shifting slide gear, reduce design difficulty, also alleviate manufacture cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional view of Fig. 1 right elevation.
Embodiment
Consult Fig. 1, Fig. 2 is the embodiment of a kind of speed-change gear box of the utility model, a kind of speed-change gear box, comprise splined shaft 1, shifting slide gear 2 and shift fork 3, described shifting slide gear 2 has at least two, described shifting slide gear 2 is arranged on the splined shaft 1, be provided with shift fork axle sleeve 4 between the described adjacent shifting slide gear 2, described shift fork axle sleeve 4 two ends are equipped with land 5, described land 5 links to each other with shifting slide gear 2, also be provided with the protruding dish 6 that matches with shift fork 3 on the described shift fork axle sleeve 4, described protruding dish 6 and land 5 be for being wholely set, and adopts bolt to be connected between described land 5 and the shifting slide gear 2.
During use, operation shift fork 3 makes protruding dish 6 drive shifting slide gear 2 and moves on splined shaft 1, makes the gear matched on different shifting slide gear 2 and the upper level axle, realizes the output of different rotating speeds.
The above only is a specific embodiment of the utility model, but technical characteristics of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
