Specific embodiment
Hereinafter embodiment of the present utility model is illustrated by particular specific embodiment, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
Embodiment 1
Refer to Fig. 1 to Fig. 8.In order to describe this utility model in detail, next this utility model is made concrete
Explanation：Close-coupled change speed gear box, including casing 6, is provided with 1 input shaft 1 and 2 output shafts 2,3 in casing 6.Input shaft 1 and output
The two ends of axle 2,3 are all arranged on the side wall of casing 6 by bearing.
Input shaft 1 is located in the middle part of casing 6, and what 2 output shafts 2,3 were symmetrical is arranged on input shaft 1 both sides position on the lower, that is,
The axis of the axis of input shaft 1 and output shaft 2,3 is not at grade.As shown in Fig. 2 such arranged, 2 output shafts 2,3
Axis spacing D3 be less than input shaft 1 and 2 output shafts 2,3 axis spacings and D1+D2 so that this apparatus structure more steps up
Gather.
Input shaft 1 is provided with 2 input gears, i.e. input gear Z1 and input gear Z2.Output shaft 3 on the left of input shaft
The upper corresponding output gear being provided with 2, i.e. output gear Z4 and output gear Z6；Also have output gear Z3 and output gear in the same manner
Wheel Z5.Wherein, output gear Z3 is identical with the output gear Z4 number of teeth, and output gear Z5 is identical with the output gear Z6 number of teeth.
In the present embodiment, input gear Z1, input gear Z2 are spindle rotationally arranged on input shaft 1 by bearing.?
Input shaft 1 is provided with clutch 4, and clutch 4 is two clutches, and this clutch 4 is located at input gear Z1 and input gear
Between Z2, clutch 4 is provided with internal spline 41, and input shaft 1 is provided with external splines 11 corresponding with internal spline 41, equally, defeated
Enter and external splines 5 corresponding with clutch 4 also is provided with gear Z1 and input gear Z2.
So arrange, input shaft 1 can be selected to pass through input gear Z1 or input gear Z2 output by clutch 4.As
Shown in Fig. 4, when the external splines 5 on the internal spline 41 of clutch 4 and the external splines 11 of input shaft 1 and input gear Z1 connects
When, during input shaft 1 rotation, output gear Z3, output gear Z4 rotation is driven by input gear Z1, thus obtaining a kind of output
Speed ratio combines.And, when output shaft 2,3 rotates, output gear Z5, output gear Z6 rotate simultaneously, and with input gear Z2
Engagement, makes input gear Z2 rotate on input shaft 1, so that output shaft 2,3 is rotated more steady.
As shown in figure 3, in the same manner, when on the internal spline 41 of clutch 4 and the external splines 11 of input shaft 1 and input gear Z2
External splines connect when, input shaft 11 rotation when by input gear Z2 drive output gear Z5, output gear Z6 rotation, thus
Obtain another kind of output speed ratio combination.
In order to more be exported speed ratio combination.Can increase gear on input shaft 1 and output shaft 2,3, that is, defeated
The gear quantity entering on axle 1 and output shaft 2,3 is 3 or more than 3, so can more be exported speed ratio combination.
