Abstract

The utility model discloses an electric-vehicle wheel, which comprises a wheel felloe (1), a cylindrical hub (3) and a wheel spoke; the cylindrical hub (3) is provided with a bearing mounting hole (2); the wheel spoke comprises a plurality of spoke sets (4) which are circumferentially distributed; the spoke set (4) comprises a spoke I (4.1) and a spoke II (4.2); the shape of the spoke I (4.1) is identical to that of the spoke II (4.2); one end of the spoke I (4.1) is connected with the edge of the left end surface of the cylindrical wheel hub (3); one end of the spoke II (4.2) is connected with the edge of the right end surface of the cylindrical wheel hub (3) which corresponds to the edge of the left end surface of the cylindrical wheel hub (3); the other end of the spoke I (4.1) and the other end of the spoke II (4.2) are simultaneously connected with the same position of the inner ring of the wheel felloe (1); the structure between the spoke I (4.1) and the spoke II (4.2) is hollow. For the electric-vehicle wheel, under the circumstance that the material of the wheel spoke is saved, the strength of the wheel spoke is better, and the service life of the electric-vehicle wheel is longer.

Description

The battery-driven car wheel

Technical field:

The utility model relates to a kind of preceding battery-driven car wheel that is installed under the electric car handle.

Background technology:

The conventional preceding battery-driven car wheel that is installed under the electric car handle all is to be made of wheel rim, spoke and wheel hub usually; Described spoke is connected between wheel rim inner ring and the wheel hub outer ring; Described wheel hub is cylindrical, and the centre is provided with and is used for bearings mounted bearing mounting hole.The principle of work of above-mentioned battery-driven car wheel is the drive by rear drive battery-driven car wheel, thereby rotates in the effect of frictional ground force.Because the driving of this battery-driven car wheel is to rotate by itself and ground-surface friction force, therefore, spoke plays crucial effects in the battery-driven car wheel, the size of its intensive parameter directly affects the service life of battery-driven car wheel, therefore, the intensive parameter of spoke becomes the problem of many battery-driven car wheels manufacturer overriding concern.At present, the spoke that is used on the battery-driven car wheel normally is made of many individual layer spokes, though the shape of spoke is of all kinds, but they all have a common characteristic, and promptly every spoke all is the diverse locations that are connected the wheel rim inner ring separately away from an end of brake gear mounting hole, in other words, the junction of every spoke and wheel hub inner ring only is subjected to the application force of a spoke, and this structure has influenced the intensity of spoke greatly, has shortened the service life of battery-driven car wheel to some extent.

The utility model content:

The technical problems to be solved in the utility model is, provides a kind of and guarantees that spoke intensity is stronger, the battery-driven car wheel of longer service life under the situation that the spoke materials more economize.

Technical solution of the present utility model is, a kind of battery-driven car wheel with following structure is provided, and it is made of wheel rim, cylindrical bosses and spoke; Described cylindrical bosses is provided with bearing mounting hole; Described spoke comprises some spoke groups to circumferential distribution; Every pair of spoke group comprises a spoke I and a spoke II; The shape of described spoke I is identical with the shape of spoke II; The end of described spoke I is connected the edge of cylindrical bosses left side; The end of described spoke II is connected the corresponding cylindrical bosses right side edge with cylindrical bosses left side edge; The other end of the other end of described spoke I and spoke II is connected the same position place of wheel rim inner ring simultaneously; Be hollow between described spoke I and the spoke II.

After adopting above structure, compared with prior art, the utlity model has following advantage: unlike the prior art, spoke in the utility model is to be made of some spoke groups to circumferential distribution, and every pair of spoke group comprises a spoke I and a spoke II, not only shape is identical with spoke II owing to spoke I, and they are not connected the same position place of wheel rim inner ring simultaneously with cylindrical bosses bonded assembly one end, in other words, what the utility model adopted is double-deck spoke, the application force that the junction of each wheel rim inner ring and spoke all can be subjected to two spokes is spoke I and spoke II and application force, therefore, the intensity of spoke is greatly improved in the utility model, thereby has prolonged service life of the present utility model; In addition, owing to be hollow between described spoke I and the spoke II, so the materials that the utility model is used for spoke relatively economize, and in other words, are reaching under the situation of equality strength, and the materials of the utility model spoke will be less than the materials of spoke on the conventional battery-driven car wheel.

Specific embodiment:

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

As shown in drawings, in this specific embodiment, the electronic car of the utility model is made of wheel rim 1, cylindrical bosses 3 and spoke; Described cylindrical bosses 3 is provided with two bearing mounting holes 2; Described spoke comprises some spoke groups 4 to circumferential distribution; Every pair of spoke group 4 comprises a spoke I 4.1 and a spoke II 4.2; The shape of described spoke I 4.1 is identical with the shape of spoke II4.2; The end of described spoke I 4.1 is connected the edge of cylindrical bosses 3 left sides; The end of described spoke II4.2 is connected the corresponding cylindrical bosses 3 right side edges with cylindrical bosses 3 left side edges; The other end of the other end of described spoke I 4.1 and spoke II4.2 is connected the same position place of wheel rim 1 inner ring simultaneously; Be hollow between described spoke I 4.1 and the spoke II4.2.
