Abstract
The utility model belongs to the technical field of rear axle tubes of electro-tricycles, and particularly relates to a middle-set-type motor rear axle tube of an electro-tricycle. The middle-set-type motor rear axle tube of the electro-tricycle comprises a left rear axle tube and a right rear axle tube, and is characterized in that the left rear axle tube and the right rear axle tube are fixedly connected into a whole through at least two gap bridge rods. The middle-set-type motor rear axle tube of the electro-tricycle has the advantages of being convenient to install, firm in structure and suitable for being popularized and applied in the field of the electro-tricycles.
Description
Technical field:
The utility model belongs to the technical field of electric tricycle rearmost axle cylinder, refers in particular to a kind of electro-tricycle built-in motor back axle cylinder.
Background technology:
Since electro-tricycle comes out, with its clean environment firendly, load carrying ability is large, the advantages such as transmission is reliable and stable are subject to everybody liking, by very fast popularization, come, along with popularizing of electro-tricycle, the defect that electro-tricycle exists also goes out thereupon, because the structure of the built-in motor back axle cylinder of electro-tricycle is in the market (referring to Fig. 1): left back bridge cylinder, right back bridge cylinder 10, 20 is split-type structural, its end face is flange plate structure, by screw 30 by a left side, right back bridge cylinder 10, 20 connect, there is following shortcoming in the back axle cylinder of this structure: split-type structural, cause installing inconvenient, be connected by screw, easily in use screw produce loosening cause firm not.
Summary of the invention:
The purpose of this utility model is to provide a kind of electro-tricycle built-in motor back axle cylinder easy for installation, well-set.
The utility model is achieved in that
An electro-tricycle built-in motor back axle cylinder, comprising: left back bridge cylinder, right back bridge cylinder, is characterized in that: between described left and right back axle cylinder, by least two gap bridge bars, be fixedly connected with and be integral.
Above-mentioned gap bridge bar is that two ends are welded on respectively on left and right back axle cylinder and the middle part concave groove protruding to both sides.
The utility model compared to existing technology outstanding advantage is:
The utility model is integral type structure, easy for installation, sound construction;
Accompanying drawing explanation:
Fig. 1 is the schematic diagram of original design;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the utility model connection structure schematic diagram.
The specific embodiment:
With specific embodiment, the utility model is further described below, referring to Fig. 2-Fig. 3:
An electro-tricycle built-in motor back axle cylinder, comprising: left back bridge cylinder 10, right back bridge cylinder 20, be fixedly connected with and be integral by two gap bridge bars 40 between described left and right back axle cylinder 10,20.
Above-mentioned gap bridge bar 40 is welded on respectively on left and right back axle cylinder 10,20 and the middle part concave groove protruding to both sides for two ends.
Flange 101 on the left back bridge cylinder 10 of the utility model is connected with motor 50 by screw 90, the flange 201 of right back bridge cylinder 20 is connected with rear wheels of electric vehicle lever shaft 80, right back bridge cylinder 20 is interior, end is provided with bearing 70, lever shaft 80 is the endoporus through left and right back axle cylinder 10,20 by bearing 70, and be connected with motor 50, between gap bridge bar 40, be provided with sprocket wheel 60, this sprocket wheel 60 is set on lever shaft 80.
The utility model is integral type structure, and easy for installation, sound construction is adapted at electro-tricycle field and applies.
Above-described embodiment is only one of preferred embodiment of the present utility model; not with this, limit practical range of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
