Abstract

The utility model discloses an electric vehicle wheel hub which comprises an outer wheel hub. The electric vehicle wheel hub is characterized in that the outer wheel hub is in the shape of a groove, and connected with an inner wheel hub through supporting ribs. Screw holes are formed in two sides of the inner wheel hub, the inner wheel hub and the outer wheel hub are formed with magnesium alloy in a casting mode, and the wall thickness of the inner wheel hub and the wall thickness of the outer wheel hub are respectively 2.5 mm. Each three supporting ribs form a set, and five sets of supporting ribs in total are evenly distributed between the inner wheel hub and the outer wheel hub. The electric vehicle wheel hub has the advantages of being strong in bearing capacity, not prone to corrosion, long in service life, attractive, light in weight, high in specific strength and specific stiffness, good in shock-absorbing capacity, and mainly applied to electric vehicles.

Description

A kind of electric bicycle wheel hub
Technical fieldThe utility model belongs to the vehicle technology field, is specifically related to a kind of electric bicycle wheel hub.
Background technologyThe electric bicycle wheel hub of prior art, mainly the inside and outside wheel hub by aluminium alloy casting is formed by connecting through driver's bar, and the inside and outside wheel hub of aluminium alloy casting and driver's bar weight capacity is poor, intensity is little easily gets rusty, and service life is short and not attractive in appearance.If improve intensity and the weight capacity of wheel hub, only have the wall thickness of strengthening wheel hub, this has increased the deadweight of productive costs and wheel hub undoubtedly.So it is imperative that the magnesium alloy material that selection intensity is high, quality is light, weight capacity is strong is produced wheel hub.
Summary of the inventionThe purpose of this utility model provides the electric bicycle wheel hub that a kind of bearing capacity is strong, be difficult for corrosion, long service life, to overcome the deficiencies in the prior art.
For achieving the above object, the utility model electric bicycle wheel hub, it comprises outer wheel hub, its main points are that outer wheel hub is the groove shape, are connected with inner wheel hub by brace rod; Described inner wheel hub both sides are provided with screw hole, and described inside and outside wheel hub is by the magnesium alloy cast moulding, and the wall thickness of described inside and outside wheel hub is 2.5mm, and three of described brace rods are one group, establish altogether five groups and are evenly distributed between the inside and outside wheel hub.
In order to make wheel hub and brake gear fixation, the screw hole of the every side of described inner wheel hub is made as 8, the 20 ° of settings of staggering of the screw hole of inner wheel hub both sides.
The utlity model has bearing capacity strong, be difficult for corrosion, long service life, the advantage such as attractive in appearance.Lightweight, strength-to-density ratio and stiffness-to-density ratio are high, damping performance is good, are mainly used in electronlmobil.
Description of drawingsFig. 1 is the utility model structural representation;
Fig. 2 is that A-A among Fig. 1 is to section-drawing.
