The beneficial effects of the utility model:
Required Multi-stage transmission is set, it is only necessary to increase gear train, mono-directional overrun clutch and centrifugal clutch the most permissible.After the rotating speed of output shaft increases, can automatic upshift successively, when output shaft rotating speed reduces, the most same automation changing down successively.
Accompanying drawing explanation
Fig. 1 is the structural representation of the automatic gear-box of the unidirectional speed governing of this utility model.
Detailed description of the invention
Below according to drawings and Examples, this utility model is described in further detail.
With reference to Fig. 1, this utility model, a kind of change speed gear box, 2,3,4,5 and one reverse gears 6 of forward gears of four different numbers of teeth installed above of axle 1.Reverse gear spline is fixed on axle 1, and forward gears all connects each via a mono-directional overrun clutch (entering marked mono-directional overrun clutch 21 in the drawings) and axle 1, so forward gears 2 can only be transferred in motion from axle 1, on 3,4,5, and forward gears 2,3,4,5 can not pass back to motion on axle 1.Four forward gears 10,11,12,13 and a reverse gear 8 is there are also installed on output shaft 14.Reverse gear 8 and output shaft 14 are slided and are joined, and the middle reverse gear 6 and 8 also having 7 power shafts 1 of a transition gear and output shaft 14 meshes together, and changes transmission direction simultaneously.There is external splines on reverse gear 8, output shaft also has external splines, gearshift sleeve 9 is provided with internal spline.Sliding at gearshift sleeve, when being fixed together by the spline on reverse gear 8 and output shaft 14, output shaft 14 is driven by reverse gear 8, is in the state of reversing gear.
Described forward gears is provided with centrifugal clutch, and whether arrange in reverse gear centrifugal clutch the most also can, if being not provided with clutch, hanging and reversing gear together with to be direct splined sleeve reverse gear hang over output shaft, when neutral and forward gear, directly disengage just.
It is cased with an outer spline sleeve on output shaft 14, and output shaft 14 is slided and joined, and only after the external splines in gearshift 9 these outer spline sleeve of sleeve and axle couples together, just can rotate together with axle 14.In this outer spline sleeve, the gear 13 of fixed first order gear, then correspond to an additionally shift gear 10, on the position of 11,12, it is fitted with centrifugal clutch, can open under the rotating speed set, corresponding gear and outer spline sleeve are linked into an integrated entity.The engaging rotating speed of these three centrifugal clutch, is respectively set to the gearshift rotating speed of second gear, third gear and fourth gear.
When spline 9 of shifting gears is in middle position, reverse gear 8 and outer spline sleeve are the most sliding joins idle running, is now neutral gear position.
When gearshift sleeve 9 slides into outer spline sleeve side, when itself and output shaft external splines are consolidated, it is forward gear state.
Because outer spline sleeve is consolidated with output shaft 14, so, after power shaft 1 drives forward gears to 2 and 13 by one-way clutch 21, directly exporting power by output shaft 14, this is the transmission of first gear.And the gear of other gear, although also it is driven to rotate, but is because respective centrifugal clutch and is in separated position, so can only dally on respective bearing.When the rotating speed of output shaft 14 reaches the gearshift rotating speed of second gear, the voussoir of the centrifugal clutch within forward gears 12 is thrown away, and forward gears 12 and output shaft outer spline sleeve are coupled together.Owing to this one-level speed reducing ratio is less than first gear transmission, so output shaft 14 can be accelerated to rotate faster, and now mono-directional overrun clutch 21 has just played the effect avoided interference with, because the rotating speed of output shaft 14 anti-tape travel gear gear 13, forward gears 2 is driven to rotate faster, having exceeded the rotating speed of power shaft 1, mono-directional overrun clutch 21 just there occurs and surmounts separation, and whole transmission has just been smoothly transitted into second gear by first gear automatically.By that analogy, when output shaft 14 rotating speed reaches third gear gearshift rotating speed, centrifugal clutch in forward gears 11 combines, front two gear gear trains surmount separation automatically, when the rotating speed of output shaft 14 reaches fourth gear gearshift rotating speed, centrifugal clutch in forward gears 10 combines, and first three gear gear train surmounts separation automatically.
When the rotating speed of output shaft 14 is reduced to fourth gear gearshift rotating speed, centrifugal clutch in forward gears 10 is separately, this primary transmission disengages, and after rotating speed drops to the speed reducing ratio that the rotating speed of power shaft 1 is multiplied by third gear, transmission is taken over by third gear, the rest may be inferred, and along with the reduction of output shaft rotating speed, transmission gear also can reduce successively.
In principle, required Multi-stage transmission can be set, it is only necessary to increase gear train, mono-directional overrun clutch and centrifugal clutch the most permissible.After the rotating speed of output shaft increases, can automatic upshift successively, when output shaft rotating speed reduces, the most same automation changing down successively.
Described embodiment only for technology of the present utility model design and feature are described, its object is to allow the personage being familiar with this art will appreciate that this utility model content and to be carried out, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain in protection domain of the present utility model.
