Abstract
The invention discloses a differential mechanism box of an electric tricycle, which relates to electric tricycles. A left box body and a right box body which are similar in the shape are symmetrically and fixedly connected together through bolts. A left box output section, a right box output section, a left box connecting section and a right box connecting section are all in a multi-edge tubular shape, a left box middle section and right box middle section are both in a polygonal pyramid tubular shape, the left box output section, the right box output section, the left box connecting section and the right box connecting section are all inequilateral multi-edge tubes, and the left box middle section and the right box middle section are polygonal pyramid tubes. Quantity of the edge surfaces of the multi-edge tubes and the polygonal pyramid tubes are equal, two adjacent edge surfaces form a plurality of ridges which are connected mutually, the ridges have the effect of reinforcing ribs, strength and rigidity of the box are enhanced, and service life of a differential mechanism is improved greatly.
Description
Technical field
The present invention relates to a kind of electro-tricycle, be specifically related to the differential mechanism casing that uses on a kind of electro-tricycle.
Background technique
The differential mechanism casing that uses on the electro-tricycle at present; Left and right casing mostly adopts alloy aluminum die casting to form; Because electro-tricycle goes on be everlasting rugged loaning, hillside, the severity of jolting requires high for tricycle differential mechanism casing intensity and rigidity.The section configuration of casing is cylindrical and conical at present, and casing intensity and rigidity are not enough, causes case of differential body deformability, breaks, and the differential gear engagement is bad, and the damage gear reduces working life, and the whole case of differential is scrapped when serious.
Summary of the invention
In order to solve the problems of the technologies described above; The present invention provides a kind of electro-tricycle differential mechanism casing; The left and right box system makes equilateral many ribs tube shape and polygonal pyramid tube shape, forms many crest lines that link up each other, plays the effect of stiffening rib; The intensity and the rigidity of casing have been strengthened, the working life of improving differential mechanism greatly.
The present invention realizes through following technological scheme: a kind of electro-tricycle differential mechanism casing, it is to be connected and fixed through the bolt symmetry by two close left box body and right cases of shape.The shape that described left and right casing is that the upper end is little, the lower end is big, be similar to wooden dipper, the small end of right case is connected with motor through the motor adpting flange.The big end of left and right casing is connected with two semiaxis respectively; The big end of described left box body from outer in be divided into three sections of left case output section, left case stage casing and left case linkage sections, the big end of described right case from outer in be divided into three sections of right case output section, right case stage casing and right case linkage sections.It is characterized in that: described left case output section, right case output section, left case linkage section and right case linkage section are many ribs tube shape, and described left case stage casing and right case stage casing are the polygonal pyramid tube shape.
Described left case output section, right case output section, left case linkage section and right case linkage section are equilateral many ribs tube shape, and described left case stage casing and right case stage casing are equilateral polygonal pyramid tube shape.
Described left case output section, left case stage casing and left case linkage section three's faceted pebble quantity equates that the crest line that adjacent two faceted pebbles form links up each other.Described right case output section, right case stage casing and right case linkage section three's faceted pebble quantity equates that the crest line that adjacent two faceted pebbles form links up each other.
Good effect of the present invention is:
1, the left and right box system makes many ribs tube shape and polygonal pyramid tube shape, forms many crest lines that link up each other, and crest line plays the effect of stiffening rib, strengthens the intensity and the rigidity of casing, the working life of improving differential mechanism greatly.
2, only need to change the shape of casing, do not increase the cost of material and the production technology of casing, be convenient to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.

Among the figure: 1, left box body, 2, right case, 3, bolt, 4, left case output section, 5, left case stage casing, 6, left case linkage section, 7, right case output section, 8, right case stage casing, 9, right case linkage section, 10, the motor adpting flange.
Embodiment
Like Fig. 1,2,3,4, shown in 5: a kind of electro-tricycle differential mechanism casing; It is to be connected and fixed through bolt 3 symmetries with right case 2 by two close left box bodies 1 of shape; Described left and right casing 1,2 is little for the upper end, the lower end big, be similar to the shape of wooden dipper; Wherein the small end of right case 2 is connected with motor through motor adpting flange 10, and the big end of left and right casing 1,2 is connected with two semiaxis respectively.The big end of described left box body 1 from outer in be divided into 6 three sections of left case output section 4, left case stage casing 5 and left case linkage sections; The big end of described right case 2 from outer in be divided into 9 three sections of right case output section 7, right case stage casing 8 and right case linkage sections.It is characterized in that: described left case output section 4, right case output section 7, left case linkage section 6 and right case linkage section 9 are many ribs tube shape; Described left case stage casing 5 is the polygonal pyramid tube shape with right case stage casing 8.
Described left case output section 4, right case output section 7, left case linkage section 6 and right case linkage section 9 are equilateral many ribs tube shape, and described left case stage casing 5 is equilateral polygonal pyramid tube shape with right case stage casing 8.Also can be many ribs of inequilateral pipe and polygonal pyramid tube shape.
Described left case output section 4, left case stage casing 5 and left case linkage section 6 threes' faceted pebble quantity equates that the crest line that adjacent two faceted pebbles form links up each other; Described right case output section 7, right case stage casing 8 and right case linkage section 9 threes' faceted pebble quantity equates that the crest line that adjacent two faceted pebbles form links up each other.Crest line plays the effect of stiffening rib, strengthens the intensity and the rigidity of casing, the working life of improving differential mechanism greatly.Only need to change the shape of casing, do not increase the cost of material and the production technology of casing, be convenient to promote the use of.
