Abstract
Electric wheel hub structure, relates to electric vehicle hub technical field.Solve existing electric vehicle hub poor universality, the technical deficiencies such as damage of easily soaking, comprise wheel rim and wheel hub motor installing ring, are evenly distributed with the spoke of five groups of integrated formed structures between wheel rim and wheel hub motor installing ring; It is characterized in that: described rim diameter a is 402.8 ± 0.5mm, the tire groove place diameter b of wheel rim is 384.4 ± 0.5mm, and the inner ring diameter c of wheel hub motor installing ring is 260 ± 2 mm.Adopt peculiar size, can compatible existing common motor cycle tire, special tyre can be produced without the need to die sinking in battery-driven car production process, reduce productive costs; User's later period maintenance Cheng Zhongke that corrects one's mistakes directly changes motor cycle tire common on market, and facilitate user to safeguard replacing, maintenance cost is low; Reduce wheel hub motor immersion probability.
Description
Technical field
The utility model relates to electric vehicle hub technical field.
Background technology
Existing electric vehicle hub is generally 10 inches or 12 inches, or less than 10 inches, and the tire used is all respective special tyre, poor universality; In addition, the wheel hub motor ground clearance being placed in wheel hub motor installing ring is little, damage of easily soaking.
Summary of the invention
In sum, the purpose of this utility model is to solve existing electric vehicle hub poor universality, the technical deficiencies such as damage of easily soaking, and proposes a kind of electric wheel hub structure.
For solving the technical matters that the utility model proposes, the technical scheme of employing is: electric wheel hub structure, comprises wheel rim and wheel hub motor installing ring, is evenly distributed with the spoke of five groups of integrated formed structures between wheel rim and wheel hub motor installing ring; It is characterized in that: described rim diameter a is 402.8 ± 0.5mm, the tire groove place diameter b of wheel rim is 384.4 ± 0.5mm, and the inner ring diameter c of wheel hub motor installing ring is 260 ± 2 mm.
Described wheel rim external profile diameter d is 431 ± 2 mm; Wheel rim outer rim width e is 72 ± 2 mm; The width of rebate f of wheel rim is 53.6 ± 0.5 mm.
Each described group spoke comprises two brace rods, and two brace rods are the V-structure of opening towards wheel rim, are provided with reinforced rib between two brace rods.
The beneficial effects of the utility model are: the utility model wheel hub adopts peculiar size, can compatible existing common motor cycle tire, can produce special tyre, reduce productive costs in battery-driven car production process without the need to die sinking; User's later period maintenance Cheng Zhongke that corrects one's mistakes directly changes motor cycle tire common on market, and facilitate user to safeguard replacing, maintenance cost is low; Reduce wheel hub motor immersion probability.
