Detailed Description

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 problems that in the prior art, the height of a welding bead on the outer periphery of a rim is too high, the welding bead is easy to interfere with a measuring bead, so that the size detection of a product is influenced, and the quality of the product is further influenced.

As shown in fig. 1 to 10, the wheel includes a rim 10 and a spoke 20, the spoke 20 is connected with the rim 10, a positioning groove 21 is opened on the spoke 20, and a circumferential edge of an axial first end of the rim 10 extends into the positioning groove 21 and forms a filling gap with a groove wall of the positioning groove 21.

In this application, constant head tank 21 has been seted up on spoke 20, stretch into the constant head tank 21 with the week edge of the first end of rim 10 axial, not only increased rim 10 and spoke 20's area of contact, guarantee can stable connection between rim 10 and the spoke 20, can also carry out preliminary location to rim 10 and spoke 20, promote the assembly efficiency of wheel, and form the packing clearance between the week edge of the first end of rim 10 axial and the cell wall of constant head tank 21, thus, can stretch into the welding rod to the packing clearance in, with rim 10 and spoke 20 welding together, the welding bead that the welding formed is located the packing clearance, can avoid the high height of welding bead to take place to interfere with the measuring ball, thereby guarantee that the size detection of product goes on smoothly, and then guarantee the quality of product.

The application provides a wheel, when carrying out fatigue durability test to the wheel, the wheel is difficult to take place to damage at welding position, has promoted the fatigue resistance ability and the security performance of wheel. Specifically, the large contact surface at the junction of rim 10 and spoke 20 provides better load and stress transfer, and when the contact surface at the junction of rim 10 and spoke 20 is small, the junction of rim 10 and spoke 20 becomes the weakest point during the transfer process, resulting in a wheel that is susceptible to failure cracking at the junction of rim 10 and spoke 20.

Alternatively, the circumferential edge of the first axial end of the rim 10 is bent toward the inner side of the rim 10 or the outer side of the rim 10 and then extends to form the positioning structure 11, and the positioning structure 11 is in clearance fit with the groove wall of the positioning groove 21. In this way, the positioning structure 11 is formed by directly bending the circumferential edge of the first end of the rim 10 in the axial direction by using the mold, and the positioning structure 11 is in clearance fit with the groove wall of the positioning groove 21, so that the contact area between the rim 10 and the spoke 20 can be further increased, and the connection stability between the rim 10 and the spoke 20 can be improved.

Alternatively, the surface of the positioning structure 11 facing the positioning groove 21 is attached to the bottom wall 211 of the positioning groove 21, and the end surface 111 of the positioning structure 11 is attached to the inner circumferential groove sidewall 212 of the positioning groove 21 or the outer circumferential groove sidewall 213 of the positioning groove 21.

Specifically, when the positioning structure 11 is formed by bending the circumferential edge of the first end in the axial direction of the rim 10 toward the inner side of the rim 10, the end surface 111 of the positioning structure 11 is attached to the inner circumferential groove sidewall 212 of the positioning groove 21, and when machining, the coaxiality of the end surface 111 of the positioning structure 11 and the rim 10 is ensured, and the coaxiality of the inner circumferential groove sidewall 212 of the positioning groove 21 and the spoke 20 is ensured, so that when the rim 10 and the spoke 20 are assembled, the coaxiality of the rim 10 and the spoke 20 is ensured by attaching the end surface 111 of the positioning structure 11 to the inner circumferential groove sidewall 212 of the positioning groove 21, and the finished quality of the wheel is ensured.

Alternatively, the end surface 111 of the positioning structure 11 is in interference fit with the inner circumferential groove sidewall 212 of the positioning groove 21, and a filling gap is formed between the surface of the positioning structure 11 far from the end surface 111 and the outer circumferential groove sidewall 213. When the end surface 111 of the positioning structure 11 is in interference fit with the inner peripheral groove sidewall 212 of the positioning groove 21, the rim 10 and the spoke 20 can be quickly and conveniently positioned, and the phenomenon that the assembly precision of the wheel is affected due to relative movement between the rim 10 and the spoke 20 is avoided.

Alternatively, the positioning groove 21 is an annular groove, the end surface 111 of the positioning structure 11 is attached to the inner circumferential groove sidewall 212 of the positioning groove 21, and the groove sectional area of the positioning groove 21 on the radial plane thereof gradually increases in the direction away from the groove bottom wall 211 of the positioning groove 21. In this way, the welding rod can be conveniently extended into the filling gap to weld the positioning structure 11 and the spoke 20.

Alternatively, the junction of the rim 10 and the spoke 20 has a first weld structure 30, and the first weld structure 30 is located in the positioning groove 21 and filled in the filling gap, the first weld structure 30 being continuously disposed around the peripheral groove sidewall 213 of the positioning groove 21. In this way, the positioning structure 11 and the spoke 20 are welded together by means of full welding, so that the spoke 20 and the rim 10 can be stably connected.

Alternatively, the junction of the rim 10 and the spoke 20 has a plurality of first weld structures 30, each first weld structure 30 being located within a positioning slot 21 and filling a portion of the fill gap, the plurality of first weld structures 30 being spaced around the peripheral slot sidewall 213 of the positioning slot 21. Thus, the number of welding rods used is reduced on the basis of ensuring stable connection between the spoke 20 and the rim 10, thereby reducing the manufacturing cost of the wheel.

Optionally, the number of welding rods is equal to or greater than 4 or equal to or less than 10.

Optionally, the joint of the rim 10 and the spoke 20 is also provided with a second bead structure 40, and the second bead structure 40 is continuously arranged; alternatively, the second bead structure 40 may be provided in plurality, and the second bead structures 40 may be provided at intervals around the outer circumferential groove side wall 213.

The skilled person can flexibly select the welding mode and the welding position according to different requirements on the strength of the wheel.

Nine specific embodiments are detailed below, based on the relationship between the depth of the positioning slot 21 and the thickness of the positioning structure 11, and the structure of the positioning slot 21:
