The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a wheel, aiming at solving the problem that in the prior art, a spoke is directly attached to a rim, and the rim and the spoke are easy to misplace, so that the finished product quality of the wheel is poor.

As shown in fig. 1 to 6, the wheel includes a rim 10 and a spoke 20, the spoke 20 is connected with the rim 10, wherein, an annular groove 211 is opened on the spoke 20, and the circumferential edge of the axial first end of the rim 10 extends into the annular groove 211 and abuts against the wall surface of the annular groove 211.

In this application, annular groove 211 has been seted up on spoke 20, like this, when assembling rim 10 and spoke 20, the circumference of the axial first end of rim 10 stretches into in annular groove 211 and with the groove wall butt of annular groove 211, thereby increased the area of contact of rim 10 with spoke 20, the stability of being connected of rim 10 and spoke 20 has been promoted, and when carrying out the welding strength test to the wheel, the wheel except bearing some load at the welding position of wheel, also can bear some load at the butt surface of rim 10 with spoke 20, thereby avoid the wheel to be damaged in the welding bears the test, the finished product quality of wheel has been promoted. The annular groove 211 can preliminarily position the rim 10, and avoids the dislocation between the rim 10 and the spoke 20, so that the assembly precision of the rim 10 and the spoke 20 is ensured, and the finished product quality of the wheel is further improved; in addition, the rim 10 and the spoke 20 do not need to be preliminarily positioned in a spot welding mode, and therefore the production efficiency of the wheel is improved.

Alternatively, the circumferential edge of the first axial end of the rim 10 is bent to form the snap structure 11, and the spoke 20 is snapped into the rim 10 by the snap structure 11 located in the annular groove 211. The circumferential edge of the first axial end of the rim 10 is bent to form the snap structure 11, so that the contact area of the snap structure 11 and the annular groove 211 is further increased, and the connection stability between the rim 10 and the spoke 20 is improved. The clamping structure 11 is clamped with the rim 10, and the wheel spoke 20 and the rim 10 are preliminarily positioned.

Considering the structure of the rim 10, the circumferential edge part of the first axial end of the rim 10 is bent to form the clamping structure 11 by directly using the die, so that the process is simple and the processing efficiency is high. According to the shape and the size of the clamping structure 11 formed by bending, the annular groove 211 is machined in the spoke 20 by means of turning, and then the clamping structure 11 of the rim 10 is embedded into the annular groove 211 of the spoke 20.

In an alternative embodiment shown in fig. 3 and 4, the circumferential edge of the first axial end of the rim 10 is bent toward the inner side of the rim 10, the surface of the snap structure 11 facing the annular groove 211 abuts against the groove bottom wall of the annular groove 211, and the end surface 111 of the snap structure 11 abuts against the inner circumferential groove side wall 212 of the annular groove 211.

In an embodiment of the present application, a circumferential edge of the first axial end of the rim 10 is bent toward an outer side of the rim 10, a surface of the snap structure 11 facing the annular groove 211 is attached to a groove bottom wall of the annular groove 211, and the end surface 111 of the snap structure 11 is attached to an outer circumferential groove side wall of the annular groove 211.

Alternatively, the inner peripheral groove sidewall 212 and the end surface 111 are the same size, i.e., the snap structure 11 just extends into the annular recess 211.

Alternatively, the inner peripheral groove sidewall 212 and the end surface 111 are interference snap fit. Thus, the rim 10 and the spoke 20 are in interference fit through the die, so that the phenomenon that the assembly precision and the finished product quality of the wheel are affected due to relative movement after the rim 10 and the spoke 20 are assembled is avoided. The inner peripheral groove side wall 212 and the end surface 111 are finished by turning, and the inner peripheral groove side wall 212 and the end surface 111 are in interference snap fit by controlling the size of the inner peripheral groove side wall 212 and the size of the end surface 111.

Alternatively, the interference between the inner peripheral groove side wall 212 of the annular groove 211 and the end surface 111 is greater than 0mm and 0.2mm or less. Tests have shown that the assembly of the rim 10 and the spoke 20 is facilitated when the interference is within the above-mentioned range.

Optionally, the depth of the annular groove 211 may be greater than the thickness of the clamping structure 11, and the clamping structure 11 can completely extend into the annular groove 211, so as to ensure that the contact area between the clamping structure 11 and the annular groove 211 is large enough, thereby ensuring the connection stability between the spoke 20 and the rim 10.

Alternatively, the depth of the annular groove 211 may be smaller than the thickness of the snap structure 11, but it is necessary to ensure that there is enough contact area between the snap structure 11 and the annular groove 211 to prevent the snap structure 11 from falling out of the annular groove 211.

The circumference of the axial first end of the rim 10 extends into the annular groove 211 and abuts against the wall surface of the annular groove 211, then the rim 10 and the spoke 20 form a wheel in a welding mode, and the coaxiality of the rim 10 and the spoke 20 is ensured, so that the coaxiality of the first rim structure and the second rim structure is ensured.

As shown in fig. 1 and 5, the support ring plate 21 is further provided with a plurality of air holes 213, and the plurality of air holes 213 are arranged around the outer periphery of the central hole 221 at intervals, so that the temperature of the tire is increased due to high temperature generated on a braking device during the braking process of the vehicle, the tire aging is accelerated, and even serious accidents such as tire ignition or tire burst can be caused, therefore, the plurality of air holes 213 are formed in the support ring plate 21, the temperature of the tire can be reduced by using the air flowing through the air holes 213, the service life of the tire is prolonged, and the use safety of the vehicle is improved.
