Description
Technical Field
The utility model belongs to the technical field of the vehicle, especially, relate to a magnesium alloy electric motor car front wheel hub.
Background
At present: with the development of society, electric bicycles or electric motorcycles have been rapidly developed, and electric bicycle hubs are important parts in electric bicycles or electric motorcycles. At present, the hub of the electric vehicle is mainly made of aluminum alloy materials, and has the disadvantages of heavy weight, poor impact resistance, weak elasticity, low strength and poor fatigue resistance. The existing front hub of the electric vehicle has the problems of heavy weight and low strength.
Through the above analysis, the problems and defects of the prior art are as follows: the existing front hub of the electric vehicle has the disadvantages of heavy weight and low strength.
The difficulty in solving the above problems and defects is: firstly, magnesium alloy is used for replacing aluminum alloy from the top to the bottom of the material, then the forming problem is solved through die casting, and the oxidation problem is solved through surface treatment.
The significance of solving the problems and the defects is as follows: the whole weight of the electric vehicle is reduced, the damping effect is improved, the strength and the impact resistance of the wheel hub are improved, the braking effect is enhanced, and the comfort and the safety of the electric vehicle during running are improved on the whole.
SUMMERY OF THE UTILITY MODEL
Problem to prior art existence, the utility model provides a wheel hub before magnesium alloy electric motor car.
The utility model discloses a realize like this, a magnesium alloy electric motor car front wheel hub is provided with: the wheel hub body, the wheel hub body mid portion mosaic is installed the brake hub, brake hub internally mounted has first bearing and second bearing, first bearing and second bearing outside cover have the axle sleeve.
Further, the hub body external diameter is 272 mm.
Further, the inner diameter of the hub body is 228 mm.
Further, the inner diameter of the innermost bearing of the hub body is 25 mm.
