Description

Gearbox

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 existing technology 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 to 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 gone, can select top gear for use, ability fuel saving and electric energy are economic, practical like this.

The utility model is realized through following technical measures: a kind of gearbox; It comprises the casing that pto is installed; Differential mechanism is installed on the pto, rotatablely in the said casing is equipped with one and two, be installed with a shaftgear one, one shaftgear two, one shaftgear three on said one; Two shaftgears, one, two shaftgears two are installed on said two; Gear ring on a said shaftgear one and the differential mechanism often meshes, and said two shaftgears one can mesh with a shaftgear two, and said two shaftgears two can mesh with a shaftgear three.

The concrete characteristics of the utility model also have, and above-mentioned two shaftgears one and two shaftgears two are shifting slide gear.

Above-mentioned two shaftgears one and two shaftgears three are sleeved on two and go up and axial restraint; Between said two shaftgears one and two shaftgears two sliding sleeve is installed; The both sides of said sliding sleeve can corresponding and said two shaftgears one and two clutches of said two shaftgears; Said two shaftgears one and a shaftgear two often mesh, and said two shaftgears two and a shaftgear three often mesh, and said sliding sleeve is connected through spline with said one.

The utility model beneficial effect is: it is reasonable in design, and is simple in structure.

Mark among the figure: 1, casing, 2, differential mechanism, 3, pto, 4, gear ring, 5, one shaftgear one, 6, a shaftgear two, 7, a shaftgear three, 8, one, 9, two shaftgears one, 10, two shaftgears two, 11, two, 12, sliding sleeve.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

A kind of gearbox; It comprises the casing that pto is installed; Differential mechanism is installed on the pto, rotatablely in the said casing is equipped with one 8 and two 11, be installed with a shaftgear 1, a shaftgear 26, a shaftgear 37 on said one 8; Two shaftgears 1, two shaftgears 2 10 are installed on said two 11; Gear ring 4 on a said shaftgear 1 and the differential mechanism 2 often meshes, and said two shaftgears 1 can mesh with a shaftgear 26, and said two shaftgears 2 10 can mesh with a shaftgear 37.

Wherein, two shaftgears one and a shaftgear two engagements, said two shaftgears two and a shaftgear three engagements can adopt two kinds of mode of structure to realize:

1, two shaftgears one and two shaftgears two are shifting slide gear, and the mode through shifting slide gear realizes engagement.

2, two shaftgears one and two shaftgears three are sleeved on two and go up also axial restraint; Between said two shaftgears one and two shaftgears two sliding sleeve is installed; The both sides of said sliding sleeve can corresponding and said two shaftgears one and two clutches of said two shaftgears; Said two shaftgears one and a shaftgear two often mesh, and said two shaftgears two and a shaftgear three often mesh, and said sliding sleeve is connected through spline with said one.

The transmission process of the utility model is following:

Top gear: two 11 are fixedly connected with engine output shaft or motor output shaft; Shaftgear 26 engagements on two shaftgears 1 and one 8; Drive one 8 rotation; Shaftgear 1 on one 8 often meshes with the gear ring 4 on the differential mechanism 2, and the output shaft 12 that drives differential mechanism rotates, power output.

Bottom gear: two 11 are fixedly connected with engine output shaft or motor output shaft; Shaftgear 37 engagements on two shaftgears 2 10 and one 8; Drive one 8 rotation; Shaftgear 1 on one 8 often meshes with the gear ring 4 on the differential mechanism 2, and the output shaft 12 that drives differential mechanism rotates, power output.

The utility model can be used realizing of existing technology without the technical characteristics of describing, and repeats no more at this.Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, the variation that those skilled in the art have done in the essential scope of the utility model, remodeling, interpolation or replacement also should belong to the protection domain of the utility model.
