Abstract
The utility model discloses a gearbox which belongs to the field of mechanical transmission and adopts the technical scheme that the gearbox comprises a main box body, wherein a first shaft and a second shaft are rotatably arranged in the main box body; a first shaft big gear and a first shaft pinion are fixedly arranged on the first shaft; a second shaft gear for axial limiting is sleeved on the second shaft; a shifting gear is also arranged on the second shaft; the first shaft pinion is meshed with the second shaft gear and can drive the second shaft gear to idle; the first shaft big gear is meshed with the shifting gear; and the shifting gear is axially separated from the second shaft gear. The gearbox has the beneficial effects of reasonable design and simplified structure and is convenient, economical and practical.
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 shaftgears of axial limiting on described two, shifting slide gear also is installed on two, the normal engagement of a described small gear and two shaftgears also can drive the idle running of two shaftgears, a described gearwheel can with the engagement of described shifting slide gear, described shifting slide gear can with the axial clutch of two shaftgears.
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 shaftgears 7 of axial limiting on described two 5, shifting slide gear 6 also is installed on two 5, a described small gear 4 and the 7 normal engagements of two shaftgears also can drive 7 idle running of two shaftgears, a described gearwheel 3 can with 6 engagements of described shifting slide gear, described shifting slide gear 6 can with the 7 axial clutches of two shaftgears.
Also be installed with bevel gear 9 on two, bull gear 12 engagements on described bevel gear 9 and the differential mechanism 11, the output shaft 10 of differential mechanism is installed on the auxiliary housing 8, and bevel gear 9 is positioned at described auxiliary housing 8, and described auxiliary housing 8 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, gearwheel 3 can with shifting slide gear 6 engagements on two 5, drives two 5 rotating powers and exports.When installing auxiliary housing additional if desired, two 5 bevel gears 9 that are positioned on the auxiliary housing part often meshs with bull gear 12 on the differential mechanism 11, and the output shaft 10 that drives differential mechanism rotates, and power is exported.
Bottom gear: fixedly connected with engine output shaft or motor output shaft for one 2, two shaftgears 7 on small gear 4 and two 5 often mesh, and two shaftgears 7 fixedly are connected as a single entity with shifting slide gear 6, drive two 5 rotating powers and export.When installing auxiliary housing additional if desired, two 5 bevel gears 9 that are positioned on the auxiliary housing part often meshs with bull gear 12 on the differential mechanism 11, and the output shaft 10 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.
