Description
Technical field
The utility model relates to a kind of speed change gear, relates in particular to a kind of gearbox.
Background technique
The gearbox of prior art can only play deceleration, differential and reversing effect, and existing gearbox has only a forward gear and a reverse gear, the forward gears design time ensures that speed per hour also will take into account climbing power, has so just caused big slope not climb, shortcomings such as the low oil consumption height of speed per hour.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and a kind of environmental protection simple in structure, reasonable in design, economic is provided, installs and uses gearbox technological scheme flexibly; And when vehicle is creeped large slope, can select bottom gear for use, and can increase climbing power like this, when flat road surface is travelled, can select top gear for use, energy fuel saving and electric energy are economic, practical like this.
The utility model is realized by following technical measures: a kind of gearbox, it comprises main box body, turn in the described main box body and be equipped with one and two, be installed with a gearwheel and a small gear on described one, be set with two small gears and two gearwheels of axial limiting on described two, on described two the slippage clutch pinion is installed also, a described gearwheel and two normal engagements of small gear also can drive two small gear idle running, the normal engagement of a described small gear and two gearwheels also can drive two gearwheels idle running, described slippage clutch pinion can be respectively with two small gears and two Large Gear Shaft During to clutch.
Further also have for of the present utility model, also be installed with bevel gear on above-mentioned two, the bull gear on described bevel gear and the differential mechanism meshes.Adopt this structure power can be commutated, make its compact overall structure.
Concrete characteristics of the present utility model also have, and the output shaft of above-mentioned differential mechanism is installed on the auxiliary housing, and described auxiliary housing is installed on the main box body.
Above-mentioned bevel gear is positioned at described auxiliary housing.
Above-mentioned one fixedly connected with engine output shaft or one fixedly connected with motor output shaft.
The utility model beneficial effect is: it is reasonable in design, and is simple in structure, and the utility model promptly can adopt single fuel oil power input, also can adopt the motor power input, and is convenient economical and practical; And when vehicle is creeped large slope, can select bottom gear for use, and can increase climbing power like this, when flat road surface is travelled, can select top gear for use, can save oil plant and electric energy like this, economic, practical.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of gearbox, it comprises main box body 1, turn in the described main box body 1 and be equipped with one 2 and two 5, be installed with a gearwheel 3 and a small gear 4 on described one 2, be set with two small gears 6 and two gearwheels 8 of axial limiting on described two 5, on described two 5 slippage clutch pinion 7 is installed also, a described gearwheel 3 and two small gear 6 normal engagements also can drive 6 idle running of two small gears, a described small gear 4 and the 8 normal engagements of two gearwheels also can drive 8 idle running of two gearwheels, and described slippage clutch pinion 7 can be respectively and two small gears 6 and two gearwheel 8 axial clutches.
Also be installed with bevel gear 13 on two, bull gear 16 engagements on described bevel gear 13 and the differential mechanism 15, the output shaft 14 of differential mechanism is installed on the auxiliary housing 12, and bevel gear 13 is positioned at described auxiliary housing 12, and described auxiliary housing 12 is installed on the main box body 1.Fixedly connected with motor or motor output shaft for described one 2.
Transmission process of the present utility model is as follows:
Top gear: fixedly connected with engine output shaft or motor output shaft for one 2, a gearwheel 3 can often mesh with two small gears 6 on two 5, and slippage clutch pinion 7 and two small gears 6 fixedly are connected as a single entity, and drives two 5 rotating powers outputs.When installing auxiliary housing additional if desired, two 5 bevel gears 10 that are positioned on the auxiliary housing part often meshs with bull gear 13 on the differential mechanism 12, and the output shaft 11 that drives differential mechanism rotates, and power is exported.
Bottom gear: fixedly connected with engine output shaft or motor output shaft for one 2, a small gear 4 can often mesh with two gearwheels 8 on two 5, and slippage clutch pinion 7 and two gearwheels 8 fixedly are connected as a single entity, and drives two 5 rotating powers outputs.When installing auxiliary housing additional if desired, two 5 bevel gears 10 that are positioned on the auxiliary housing part often meshs with bull gear 13 on the differential mechanism 12, and the output shaft 11 that drives differential mechanism rotates, and power is exported.
The utility model can not repeat them here with the realizing of prior art without the technical characteristics of describing.Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art have done in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
