EMT magnesium alloy two - wheeled electric vehicle wheel hub takes magnesium alloy lightweight material as the core. With the unique advantages of the material, it brings performance upgrading to two - wheeled electric vehicles and a new riding experience to users.
In terms of material characteristics, the density of magnesium alloy is only 1/4 of that of steel and 2/3 of that of aluminum, which significantly reduces the weight of the wheel hub. It is about 40%-60% lighter than the traditional steel wheel hub and 15%-30% lighter than the aluminum alloy wheel hub. At the same time, magnesium alloy has extremely high specific strength and specific stiffness. While achieving lightweight, it can withstand various stresses during the driving of electric vehicles, including the impact from road bumps and the pressure of the vehicle body weight, with extremely strong structural stability. In addition, magnesium alloy has excellent thermal conductivity, about 1.5 times that of aluminum alloy, which can quickly dissipate the heat generated by the wheel hub during high - speed rotation, reducing the loss to the tire and the wheel hub itself due to overheating. Moreover, magnesium alloy also has good shock absorption, which can absorb part of the vibration during driving.
These characteristics bring excellent user experience. The reduction in the weight of the wheel hub directly reduces the unsprung mass of the electric vehicle, making the vehicle start and accelerate more easily and labor - saving, and the cruising range can also be improved to a certain extent, so that users do not need to frequently worry about the power problem during daily commuting or short - distance travel. The extremely high strength and stability ensure riding safety. Even under complex road conditions, it can effectively avoid deformation or damage of the wheel hub, making users ride more at ease. The excellent heat dissipation performance prolongs the service life of tires and wheel hubs and reduces maintenance and replacement costs. The good shock absorption improves riding comfort, reduces the sense of bumpiness, and makes it not easy to feel tired during long - time riding.
