Abstract

The invention relates to an axle-less wheel. The axle-less wheel comprises hubs, permanent magnet blocks, high-speed bearings and a connecting frame. The inner hub is hollow in the middle; a sprocketwheel and a disc brake which are fixed by the outer hub are in contact with the inner hub and the connecting frame respectively through a circular array high-speed bearing set or the permanent magnetblocks repellent in magnetism, and the sprocket wheel is connected with a small sprocket wheel fixed by a motor in front of the connecting frame through a chain; the connecting frame is connected to one side of the inner hub through a single side. By optimizing the design, the array high-speed bearings can be used for making the outer hub and a synchronous belt pulley or the synchronous belt pulley rotate around the hollow inner hub, and the built-in hub motor can provide built-in power for the axle-less wheel, so that the cost is reduced, the friction caused by oil sealing is decreased, and the axle-less wheel is provided for a vehicle; the permanent magnet blocks which are repellent in magnetism and are provided with oppositely arranged magnetic poles can also be in contact with an innerhub structure, so that an outer hub structure is magnetically suspended on the inner hub structure, the friction is greatly decreased, and losses are reduced.

Description

technical field [0001] The invention relates to a shaftless wheel whose inner hub is hollow, power is transmitted through a sprocket or a synchronous pulley, and an array bearing is used to rotate or a permanent magnet block is used to form a magnetic levitation. Background technique [0002] At present, the tires of known vehicles are all made up of cover tires and inflated inner bladders, which are prone to tire blowouts and accidents; the hubs of the wheels of motorcycles and electric vehicles are all solid, with central axles, which have not changed always. Patent 201420785004.0 discloses a shaftless wheel, which can make the center of the electric vehicle shaftless. However, the patent considers inaccurate seals and bearings, making it easy for water to enter the interior and burn the coils, and the wear of the hub will be rapid after the steel balls roll, causing the wheel to fail to operate. Patent 201620673750.X discloses a shaftless wheel, which can make the center...
