Problems solved by technology
[0003] Because the movement tracks of the rear wheels and the front wheels of the electric tricycle are inconsistent, that is, the rear wheels on both sides push the front wheel in the middle, so when changing direction, the torque force on both sides of the front hub is greater than that of the rear hub. If the front hub simultaneously With the drum brake structure and aluminum alloy material, the torque force will become larger during braking, and the aluminum alloy material with poor fatigue resistance cannot withstand the impact of torque force on the shaft hole during long-term driving, and will Faults such as shaft hole wear, bearing loosening, and wheel hub falling off occur. In the existing technology, only the rear hub with a small torque force can use drum brakes and aluminum alloy materials at the same time.

Embodiment Construction
[0012] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0013] Such as figure 1 As shown, the drum-brake aluminum alloy front wheel hub for an electric tricycle is characterized in that it includes a rim 1, a spoke 2 combined with the rim 1, and a shaft mounting part 3 at the center of the circle of the rim 1, where the shaft is mounted The part 3 and the rim 1 are connected and supported by the spokes 2, and the materials are integrally cast with aluminum alloy materials, and the characteristic is that: the outer periphery of the shaft installation part 4 is distributed with a brake drum 6, and the shaft installation part 3 includes a shaft Hole 4, the shaft hole 4 is used to install the bearing, the shaft is hinged in the shaft hole 4 through the bearing, the shaft hole 4 is also embedded with a wear-resist...

The invention discloses a drum brake type aluminum alloy front wheel hub used for an electric tricycle. The front hub is characterized in that the hub includes wheel rims, spokes combining with the wheel rims, and a shaft installation part of the circle centers of the wheel rims; the shaft installation part is connected to the wheel rims through the spokes so that supporting can be achieved; the front hub is integrally casted by adopting an aluminum alloy material; the periphery of the shaft installation part is distributed with brake drums; the shaft installation part includes a shaft hole; the shaft hole is used for installing a bearing; a shaft can be hinged in the shaft hole through the bearing; a wear-resistant sleeve is embedded in the shaft hole; the outer surface of the wear-resistant sleeve is in contact with the inner surface of the shaft hole; and the bearing is located in the wear-resistant sleeve. Thus, the technical problem that an aluminum alloy front wheel hub of an electric tricycle cannot use drum brakes can be solved; and the front hub had advantages of impact resistance, wear resistance and long service life.
Description
technical field [0001] The invention relates to the technical field of electric wheel hubs, in particular to a drum-brake aluminum alloy front wheel hub for electric tricycles. Background technique [0002] The wheel hub of the electric tricycle is installed on the central shaft of the front fork through the interchangeable hub, the interchangeable hub is matched with the central shaft through the bearing, and the wheel hub is fixed on the interchangeable hub through bolts, so the front wheel hub of this structure requires more processes during assembly Firstly, the interchangeable hub and the center shaft will be assembled, and then the front wheel and the wheel hub will be fixed with bolts after assembly. In the prior art, in order to reduce the assembly process, the interchangeable hub and the wheel hub are integrated into a cast structure. [0003] Because the movement tracks of the rear wheels and the front wheels of the electric tricycle are inconsistent, that is, the ...
