Steel hub of electric tricycle

Technical Field

The utility model relates to a wheel hub technical field, concretely relates to electric tricycle steel wheel hub.

Background

With the improvement of living standard of people, the electric tricycle has gone into thousands of households, and becomes a tool for replacing walking of many consumers. The novel bicycle is small in appearance, convenient to ride, energy-saving and environment-friendly, and accords with the low-carbon concept. The hub is used as an important part of the electric tricycle, the operation is complex during processing, the cost is higher, and certain influence is brought to the economic benefit and the market competitiveness of the product. Currently, hubs or rims made of two materials, one made of steel and the other made of aluminum alloy, are popular in the market. The aluminum alloy hub wins the favor of many vehicle owners and friends due to the characteristics of elegant appearance, safety, comfort and the like, and a plurality of new vehicle types and luxury vehicle types are the aluminum alloy hubs. Even some people buy low-mix vehicle models, the steel wheel hub is provided with an ornament similar to an aluminum alloy wheel hub so as to improve the color value of the vehicle. The aluminum alloy hub is indeed stronger in bearing pressure capacity and theoretically stronger, but the weakness of the brittle material is also that it is exposed. When a vehicle collides or runs through a pothole road section at high speed, the aluminum alloy hub is easy to break, and more serious consequences can be caused. The steel hub has a rough outer surface but has a 'soft' core, so that the steel hub cannot cause larger loss due to sudden fracture in an emergency. The steel hub is also more advantageous in terms of safety during use.
