Embodiment Construction

[0010] The present invention will be described in detail below with reference to the accompanying drawings.

[0011] In the accompanying drawings, 1 is an outer hub, 2 is a disc brake, 3 is a bearing ring, 4 is an inner hub, 5 is a coil, 6 is a permanent magnet, 7 is a hole, 8 is an oil seal, and 9 is an oil tank.

[0012] figure 2 The structure of the first embodiment of the axleless wheel is shown. As shown in the figure, the wheel is composed of an outer hub (1) and an inner hub (4). The middle of the inner hub (4) is hollow without a shaft, which is the frame structure of the wheel, so it looks like there is a center in the middle of the existing wheel. The shaft support is different. This patent does not have this shaft, which looks like a shaftless structure; the inner hub (4) is fixed with an inner bearing ring (3) with a "Z"-shaped contact surface away from the center, and the outer hub (4) is fixed with a The outer bearing ring (3) with a "Z"-shaped contact surface...

Abstract

The invention relates to a shaft-less wheel, which comprises wheel hubs, an oil seal and bearing collars, wherein the wheel consists of an outer wheel hub and an inner wheel hub, and the middle part of the inner wheel hub is hollow; the inner wheel hub is fixedly provided with a stator wound with a coil, an oil tank and an inner bearing collar of which the contact surface far away from the center is Z-shaped; the inner bearing collar is provided with a hole, and the oil tank is connected with the hole through a pipeline; the outer wheel hub is fixedly provided with a permanent magnet and an outer bearing collar of which the contact surface facing the center is Z-shaped and which has a Babbitt layer; the inner and outer wheel hubs are connected through the bearing collars respectively. According to the shaft-less wheel, an optimal design is adopted, the bearing collar with a Z-shaped section and the Babbitt layer is used as a bearing, and by the hole of the bearing collar, a related lubricant and the oil seal, the size and weight of the bearing can be reduced, the friction coefficient can be greatly reduced, and the service life can be prolonged; by more than one layer of coil, the energy consumption can be reduced.

Description

technical field [0001] The invention relates to an axleless wheel in which an outer hub is connected to an inner hub through a Z-shaped bearing ring. 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. Contents of the invention [0003] In order to overcome above-mentioned defective, the present invention provides a kind of shaftless wheel, and its composition is as follows: [0004] A ...
