Description
Technical Field
The utility model relates to a wheel for electric motor car.
Background
With the concern of people on environmental protection, the electric vehicle gradually becomes one of the main transportation tools for people to go on a short trip; one of the common failures of the electric vehicle is that the electric vehicle is easy to puncture and burst; when the tire of the electric vehicle is punctured, the outer tire and the inner tire are pressed together, and the inner tire and the hub rotate synchronously because the air tap of the inner tire is fixed on the hub of the electric vehicle; the common outer tire is clamped on the hub, when the electric vehicle is pushed, the outer tire and the inner tire are staggered, and the sharp pricks on the outer tire are fixed and clamped on the outer tire after the tire is pricked and exploded, so that the inner tire is continuously pricked by the sharp pricks on the outer tire in the process of pushing the electric vehicle and the inner tire and the outer tire to be staggered, a series of holes are easily pricked on the inner tire, and the damage degree of the inner tire is increased; on the other hand, the electric vehicle is pushed under the state of no air, so that the inner tube is easy to crush; this is also the reason why the tire cannot be pushed for a long time when it is flat; the traditional electric vehicle is very weak after the tire is deflated, has heavy weight and cannot be pushed for a long time, and great inconvenience is caused to the stroke.
In addition, the tires adopted on the existing electric locomotive are solid tires, when the electric locomotive runs on an uneven road surface, the uneven road surface generates great vibration to the tires, although most of the vibration is absorbed by the shock absorber, a part of vibration acting force is still transmitted to the seat to influence a passenger, and in the process, the solid tires can also absorb some vibration force, but the vibration acting force absorbed by the solid tires is too little, and the vibration is not obvious to the falling.
Disclosure of Invention
The utility model provides a wheel for electric motor car, electric motor car are at the in-process of traveling, the utility model discloses a wheel can obviously reduce the vibrations that receive.
The technical scheme for solving the technical problems is as follows:
a wheel for electric motor car, including wheel hub, axle, stator, rotor and the tire of setting on wheel hub, wheel hub rotationally sets up epaxial, and the stator is located wheel hub and fixed with the axle, and the rotor is located wheel hub and fixed with wheel hub, the tire is solid child, be equipped with a plurality of holes that are used for reducing the tire vibrations on the tire, the axial in hole and the axial direction parallel of tire.
The holes comprise a first hole and a second hole, the axial directions of the first hole and the second hole are parallel to the axial direction of the tire, and the first hole and the second hole are blind holes.
The holes comprise a first hole and a second hole, the axial directions of the first hole and the second hole are parallel to the axial direction of the tire, the first hole is a blind hole, and the second hole is a through hole.
The holes comprise a first hole and a second hole, the axial directions of the first hole and the second hole are parallel to the axial direction of the tire, the first hole and the second hole are through holes, and the first hole and the second hole are located on different cross sections.
When the electric vehicle runs and the wheels are vibrated, the vibration acting force firstly acts on the tire, and because the tire 5 is provided with the hole parallel to the axial direction, the vibration acting force enables the tire to deform at the position provided with the hole, so that the tire absorbs the vibration acting force, the transmission of the vibration acting force to the vehicle body and the part above the vehicle body is reduced, and the comfort of passengers is improved.

Detailed Description
Example 1
As shown in fig. 1, the utility model discloses a wheel for electric motor car, including wheel hub 1, axle 2, stator 3, rotor 4 and the tire 5 of setting on wheel hub 1, wheel hub 1 rotationally sets up on axle 2, preferably, sets up the mounting hole at wheel hub 1's both ends, installs bearing 6 in the mounting hole respectively, axle 2 and bearing 6 cooperation back make wheel hub 1 can rotate counter shaft 2 under the exogenic action. The two ends of the shaft 2 are fixedly connected with the frame, and the shaft 2 does not rotate in the driving process of the electric vehicle. The stator 3 is located in the hub 1 and fixed with the shaft 2, and the rotor 3 is located in the hub 1 and fixed with the hub 1. The tire 5 is a solid tire, the tire 5 is provided with a plurality of holes for reducing tire vibration, and the axial direction of the holes is parallel to the axial direction of the tire 5.
When the electric vehicle runs and the wheels are vibrated, the vibration acting force firstly acts on the tire 5, and the tire 5 is provided with holes parallel to the axial direction, so that the tire 5 deforms at the positions provided with the holes, the vibration acting force is absorbed by the tire 5, the transmission of the vibration acting force to the vehicle body and parts above the vehicle body is reduced, and the comfort of passengers is improved.
As shown in fig. 1, the holes include a first hole 7 and a second hole 8, the axial directions of the first hole 7 and the second hole 8 are parallel to the axial direction of the tire, and both the first hole 7 and the second hole 8 are blind holes. First hole 7 and second hole 8 adopt the structure of blind hole for not only the intensity of tire has obtained the assurance, has played the absorbing effect simultaneously moreover. Further, the arrangement positions of the first holes 7 and the second holes 8 are not limited, and the first holes 7 and the second holes 8 may be located on the same cross section of the tire 5 or different cross sections in the radial direction of the tire, or a part of the first holes 7 and the second holes 8 may be located on the same cross section.
