Abstract

The utility model relates to a shaftless wheel, it includes: wheel hub and bearing steel graphite bearing circle. Wherein, the wheel comprises outer hub who is fixed with the magnet piece and the interior wheel hub who is fixed with the coil, and is hollow in the middle of the interior wheel hub, interior wheel hub and outer wheel hub are connected through the inner circle and the outer lane of cross -section for the bearing steel graphite bearing circle of " Z " font respectively. Outer hub is connected with the dish piece of stopping, interior wheel hub is connected with the brake ware, outer hub is fixed with the tire. There are the spring and the medial surface of race ring inner circle to contact in the interior wheel hub. The inner circle of race ring inner circle and interior wheel hub are through recess and corresponding protruding being connected. Through the optimal design, the bearing steel graphite bearing circle that utilizes the cross -section to be " Z " font is fixed and is kept high -speed rotation with outer wheel hub as self -lubricating bearing and sealing ring, the interior wheel hub of messenger, coil and magnet piece can make the wheel rotate, the dish is stopped piece and dish and is stopped the ware and can make the wheel stall in case of necessity.

Description

A kind of shaftless wheel

Technical field

This utility model relates to the shaftless wheel that a kind of outer wheel hub is connected with inner wheel hub by the bearing steel graphite bearing circle that cross section is " Z " font。

Background technology

At present, the tire of known vehicle forms by the inner bag of cover tire and inflation, it is easy to blows out, accident occurs；The axle at the wheel Jun You center of motorcycle and electric motor car, never changes。Patent 201420785004.0 discloses a kind of shaftless wheel, it is possible to make electric motor car center shaftless。But this patent is sealing and considering inaccurate on bearing, make water be easily accessible inside and burn out coil, and after steel ball rolling, the abrasion of wheel hub quickly, can be caused that this wheel cannot run。

Utility model content

In order to overcome drawbacks described above, this utility model provides a kind of shaftless wheel, being constructed as follows of it:

A kind of shaftless wheel, it includes: wheel hub and bearing steel graphite bearing circle。Wherein, wheel outer wheel hub and inner wheel hub composition, inner wheel hub central hollow；Inner wheel hub is connected with the bearing steel graphite bearing circle that cross section is " Z " font that connects through of outer wheel hub。

Described wheel, wherein, outer wheel hub is fixed with magnet piece, and is connected with the outer ring of race ring by connector, and connector is connected to disc brake sheet；Inner wheel hub is fixed with coil, and coil both sides, inner wheel hub inherence are fixed with the inner ring of mirror symmetry race ring, and inner wheel hub is connected to brake；Outer wheel hub is fixed with tire。Spring is had to contact with the medial surface of race ring inner ring in inner wheel hub。The inner ring of race ring inner ring is connected by groove and corresponding projection with inner wheel hub。

The utility model has the advantages that: by optimizing design, the bearing steel graphite bearing circle utilizing cross section to be " Z " font, as self-lubricating bearing and sealing ring, makes inner wheel hub fixing and outer wheel hub keeps high-speed rotation；Coil and magnet piece can make wheel turns；Disc brake sheet and disc brake can make wheel stop operating when necessary。

Detailed description of the invention

With reference to the accompanying drawings this utility model is described in detail。

In the accompanying drawings, 1 is outer wheel hub, and 2 is disc brake, and 3 is race ring, and 4 is inner wheel hub, and 5 is coil, and 6 is permanent magnet。

Fig. 1 illustrates the structure of shaftless wheel。As it can be seen, wheel outer wheel hub (1) and inner wheel hub (4) composition, be shaftless hollow in the middle of inner wheel hub (4), for entirety composition structure；Inner wheel hub (4) is connected with bearing steel graphite bearing circle (3) that cross section is " Z " font that connects through of outer wheel hub (1), two such race ring forms a bearing, graphite self-lubricating can either be passed through, again can load-bearing, wear-resisting and resistance to high speed rotating, and autologous define sealing ring, without adding sealing ring again, and greatly reduce than the volume and weight of ball bearing and needle bearing, greatly reduce cost；Two mirror symmetry race rings (3) can form inside and outside load-bearing and left and right load-bearing is integrated, and installation is convenient to。Outer wheel hub (1) is fixed with magnet piece (6), and is connected by the outer ring of connector with race ring (3), so makes the gravity that outer ring load-bearing outer wheel hub (1) of race ring (3) is formed, and connector is connected to disc brake sheet, for outer wheel hub overall structure；Inner wheel hub (4) is fixed with coil (5), the magnet piece (6) fixing with outer wheel hub (1), form motor, can rotate after energising, inherent coil (5) both sides of inner wheel hub (4) are fixed with the inner ring of mirror symmetry race ring (3), the inner ring of such race ring (3) bear outer ring gravity and pass to inner wheel hub (4), and when making inner wheel hub (4) fixing, outer wheel hub can rotate；Inner wheel hub (4) is connected to brake (2), the brake block being connected with outer wheel hub (1), forms brake system, it may be necessary to brake；Outer wheel hub (1) is fixed with tire, and for walking and damping, wherein tire can be pneumatic tire, it is possible to by non-inflatable tyre or solid tyre, solve to blow out problem。Spring is had to contact with the medial surface of race ring (3) inner ring in inner wheel hub (4), so can by the elastic force of spring, make the inner ring of race ring contacting with outer ring tightly horizontal direction, when running up, play the effect of sealing and prevent whole race ring from loosening。The inner ring of race ring (3) inner ring is connected by groove and corresponding projection with inner wheel hub (4), so be conducive to installing and preventing the slip of race ring (3), the lateral surface of race ring (3) inner ring is contacted with inner wheel hub (4) by sealing ring if desired, starts sealing function。

This utility model is applicable to electric motor car, battery-operated motor cycle and electric automobile。
