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 a kind of electro-tricycle uses.
Background technique
The differential mechanism casing that current electro-tricycle uses, left and right casing mostly adopts alloy aluminum die casting to form, because electro-tricycle travels on be everlasting rugged loaning, hillside, the severity of jolting, for tricycle differential mechanism casing intensity and rigid requirements high.The section configuration of current casing is cylindrical and conical, and casing intensity and rigidity not, cause case of differential body deformability, break, and differential gear engagement is bad, and damage gear, reduce working life, time serious, the whole case of differential is scrapped.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of differential mechanism box of electric tricycle, left and right box system is made equilateral many ribs tube shape and polygonal pyramid tube shape, form many crest lines mutually linked up, play the effect of stiffening rib, enhance intensity and the rigidity of casing, greatly improve the working life of differential mechanism.
The present invention is achieved through the following technical solutions: a kind of differential mechanism box of electric tricycle, and it is connected and fixed by bolt symmetry by the close left box body of two shapes and right case.Described left and right casing is that upper end is little, lower end large, is similar to the shape of wooden dipper, and the small end of right case is connected with motor by motor adpting flange.The large end of left and right casing is connected with two semiaxis respectively, the large end of described left box body from outer in be divided into left case output section, left case stage casing and left case linkage section three sections, the large end of described right case from outer in be divided into right case output section, right case stage casing and right case linkage section three 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, described left case stage casing and right case stage casing are 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.
The faceted pebble quantity of described left case output section, left case stage casing and left case linkage section three is equal, and the crest line that adjacent two faceted pebbles are formed links up mutually.The faceted pebble quantity of described right case output section, right case stage casing and right case linkage section three is equal, and the crest line that adjacent two faceted pebbles are formed links up mutually.
Good effect of the present invention is:
1, left and right box system is made many ribs tube shape and polygonal pyramid tube shape, and form many crest lines mutually linked up, crest line plays the effect of stiffening rib, strengthens intensity and the rigidity of casing, greatly improves the working life of differential mechanism.
2, only need change the shape of casing, not increase cost of material and the production technology of casing, be convenient to promote the use of.

Embodiment
As shown in Fig. 1,2,3,4,5: a kind of differential mechanism box of electric tricycle, it is connected and fixed by bolt 3 symmetry by the close left box body 1 of two shapes and right case 2, described left and right casing 1,2 is that upper end is little, lower end large, is similar to the shape of wooden dipper, wherein the small end of right case 2 is connected with motor by motor adpting flange 10, and the large end of left and right casing 1,2 is connected with two semiaxis respectively.The large end of described left box body 1 from outer in be divided into left case output section 4, left case stage casing 5 and left case linkage section 6 three sections; The large end of described right case 2 from outer in be divided into right case output section 7, right case stage casing 8 and right case linkage section 9 three 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 and right case stage casing 8 are polygonal pyramid tube shape.
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 and right case stage casing 8 are equilateral polygonal pyramid tube shape.Also can be inequilateral many ribs pipe and polygonal pyramid tube shape.
The faceted pebble quantity of described left case output section 4, left case stage casing 5 and left case linkage section 6 three is equal, and the crest line that adjacent two faceted pebbles are formed links up mutually; The faceted pebble quantity of described right case output section 7, right case stage casing 8 and right case linkage section 9 three is equal, and the crest line that adjacent two faceted pebbles are formed links up mutually.Crest line plays the effect of stiffening rib, strengthens intensity and the rigidity of casing, greatly improves the working life of differential mechanism.Only need change the shape of casing, not increase cost of material and the production technology of casing, be convenient to promote the use of.
