Description
Technical field
This utility model relates to a kind of shifting system, especially relates to a kind of coaxial shifting system.
Background technology
At present, on a lot of vehicles use mechanical gearbox, be mostly arrange on two axles or three axles several groups mutual
Meshed gears, by changing engagement situation, it is achieved advances, retreat and the state such as parking, although this gear structure
Reliable and stable, transmission efficiency is high, but its radial dimension is relatively big, then cannot install and use for some little lilliput cars, is suitable for model
Enclose narrower and relatively costly.
Summary of the invention
This utility model is aiming at the technical problem that the existing shifting system scope of application is narrower and relatively costly, it is provided that one
Kind of the scope of application is relatively wide and lower-cost coaxial shifting system.
To this end, this utility model is provided with housing, in housing, it is provided with power input device, PTO, gearshift
And drive system；Power input device is power shaft, and power shaft passes through bearings on housing；PTO is output
Gear, output gear is sheathed on power shaft and can rotate around power shaft；Gearshift is provided with reverse gear, advance tooth
Wheel and gearshift ring, gearshift ring can engage with reverse gear and forward gear respectively；Reverse gear is fixed on housing, advance tooth
Wheel be fixed on power shaft by spline, reverse gear and forward gear adjacent and be located at gearshift ring the same side.
Preferably, drive system is provided with the first sun gear, the first row star-wheel, the second sun gear, the second planetary gear and planet
Frame；First sun gear is fixed on power shaft, and the first row star-wheel is located at the periphery of the first sun gear；Second sun gear is rotating
Being located on power shaft, the second planetary gear is located at the periphery of the second sun gear；Planet carrier one side and the first row star-wheel and the second row
Star-wheel matches, and is on the other hand connected with gearshift ring by spline, and gearshift ring can move freely along spline horizontal direction.
Preferably, the first sun gear is being located on power shaft of integral type, planet carrier also by bearings at power shaft
On.
Gearshift of the present utility model can realize advance on same axis, retreat and stop Three models, and it has
The feature such as compact conformation, radial dimension be little and cost is relatively low.Carry this gearshift, the volume of change speed gear box can be effectively reduced,
The scope of application is more extensive.
Accompanying drawing explanation

Fig. 2 is generalized section of the present utility model.
Symbol description in figure:
1. power shaft；2. reverse gear；3. forward gear；4. gearshift ring；5. planet carrier；6. the first sun gear；7. first
Planetary gear；8. the second planetary gear；9. output gear；10. housing；11. second sun gears.
Detailed description of the invention
Describe detailed description of the invention of the present utility model with reference to the accompanying drawings in detail.
As depicted in figs. 1 and 2, this utility model is provided with housing 10, is provided with power input device, power output in housing 10
Device, gearshift and drive system.Power is passed to power by drive system by power input device of the present utility model
Output device, gearshift is for changing the direction of drive system transmission power.
Power input device is power shaft 1, and power shaft 1 is by bearings on the housing 10.PTO is defeated
Going out gear 9, output gear 9 is sheathed on power shaft 1 and can rotate around power shaft 1.Gearshift is provided with reverse gear
2, forward gear 3 and gearshift ring 4, gearshift ring can engage with reverse gear 2 and forward gear 3 respectively.Reverse gear 2 is fixed on
On housing 10, forward gear 3 is fixed on power shaft 1 by spline, and reverse gear 2 and forward gear 3 are adjacent and be located at gearshift
The same side of ring 4.Reverse gear 2 is identical with forward gear 3 diameter.
Drive system is provided with the first sun gear 6, the first row star-wheel the 7, second sun gear the 11, second planetary gear 8 and planet carrier
5.First sun gear 6 being located on power shaft 1 in integral type, the first row star-wheel 7 is located at the periphery of the first sun gear 6；Second too
Sun wheel 11 is rotating to be located on power shaft 1, and the second planetary gear 8 is located at the periphery of the second sun gear 11；Planet carrier 5 one aspect with
The first row star-wheel 7 and the second planetary gear 8 match, and are on the other hand connected with gearshift ring 4 by spline, and gearshift ring 4 can be along flower
Key horizontal direction moves freely.Planet carrier 5 also by bearings on power shaft 1.
Below work process of the present utility model is illustrated.
When ring 4 of shifting gears is moved to the left and engages with back gear 2, the power of power shaft 1 by the first sun gear 6, the
One planetary gear 7, planet carrier the 5, second planetary gear 8 and the second sun gear 11 pass to output gear 9, due to gearshift ring 4 both with row
Carrier 5 matches and is meshed with reverse gear and reverse gear is fixing on the housing 10, so the rotation direction of output gear 9
Contrary with turning to of power shaft 1, thus realize reverse gear；If when gearshift ring 4 be moved to the left back gear 2 and forward gear 3 it
Between time, power shaft 1 then dallies, and switches to neutral；If gearshift ring 4 is moved to the left when engaging with forward gear 3, power shaft 1 with
Output gear 9 turns to identical, it is achieved drive shift.
Only as described above, only specific embodiment of the utility model, when not limiting this utility model with this
The scope implemented, therefore the displacement of its equivalent assemblies, or the equivalent variations made according to this utility model scope of patent protection and amendment,
All should still belong to the category that this utility model claims are contained.
