Description

Reinforced wheel rims

technical field

The utility model relates to the field of wheel accessories, in particular to a reinforced wheel rim.

Background technique

The wheel is an important part used to transmit the rotating load and support the load between the axle and the tire. It is generally composed of a rim and spokes, and the rim plays the role of assembling the tire. Under the extrusion action of the tire, the rim of the wheel bears a large pressure, so its strength plays a decisive role in the bearing capacity and operating life of the wheel.

The Chinese patent "A tubeless wheel rim with ribs (201721034974.7)" discloses a wheel rim with ribs. The specific structure is that at least one rib is provided in the wheel groove to increase the overall strength. . The setting of this reinforcing rib is to repair the welding on the outer surface of the wheel groove, which is not only complicated in process, but also easily damages the overall structure of the rim, which is time-consuming and laborious, with high working intensity and low efficiency. The overall appearance of the wheel rim.

Utility model content

The utility model aims at the technical defects mentioned in the background technology, and provides a reinforced wheel rim which is integrally formed by pressing, has high strength, and is beautiful and clean.

The technical solution adopted by the utility model is: a reinforced wheel rim, including a first bead seat and a second bead seat constituting the rim body, the outer circumference of the first bead seat is the inner rim, and the second bead seat The outer circumference is the outer rim, and the space between the first bead seat and the second bead seat is a wheel groove, and the central part of the wheel groove is provided with a first reinforcing convex peak along its circumference;

A second reinforcing convex peak is provided at the junction between the outer side of the wheel groove and the second bead seat.

The first reinforcing convex peak is 2-2.5mm higher than the outer surfaces of the wheel grooves on both sides.

The first reinforcing convex peak is 2-2.5 mm higher than the outer surface of the second bead seat on the outer side.

The outer circumference of the inner rim is 15-18mm higher than the outer surface of the first bead seat.

The outer circumference of the outer rim is 23-25mm higher than the outer side of the second bead seat.

Both the first reinforcing convex peak and the second reinforcing convex peak are integrally formed by pressing the rim body.

Compared with the prior art, the utility model has a simple structure, and the first reinforcing convex peak and the second reinforcing convex peak are integrally pressed and formed with the rim body, with high strength, neat appearance, simple process, and time-saving and labor-saving.

In the figure: inner rim 1, wheel groove 2, outer rim 3, first bead seat 4, first reinforcing convex peak 5, second reinforcing convex peak 6, second bead seat 7.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Referring to accompanying drawings 1-3, the wheel rim disclosed by the utility model is an improvement on the basis of the existing rim, and the pressing of the reinforcing rib part is added in the production process of the existing rim body.

This reinforced wheel rim includes a first bead seat 4 and a second bead seat 7 constituting the rim body, the outer circumference of the first bead seat 4 is the inner rim 1, and the outer circumference of the second bead seat 7 is the outer rim 3. Between the first bead seat 4 and the second bead seat 7 is the wheel groove 2 . The central part of the wheel groove 2 is provided with an annular first reinforcing convex peak 5 along its circumference, that is, a reinforcing rib protruding outward. A second reinforcing peak 6, that is, a reinforcing rib protruding outward, is provided at the junction between the outer side of the wheel groove 2 and the second bead seat 7. Both the first reinforcing convex peak and the second reinforcing convex peak are an integral structure formed by pressing the rim body, and both have a smooth curved surface transition.

As a preferred technical solution: the first reinforcing convex peak is 2-2.5 mm higher than the outer surfaces of the wheel grooves on both sides. The first reinforcing convex peak is 2-2.5 mm higher than the outer surface of the second bead seat on the outer side. The two integrally formed convex peaks enhance the overall compressive strength of the rim, and the smooth curved surface formed by integral pressing improves the cleanliness of the overall appearance.

The outer circumference of the inner rim is 15-18mm higher than the outer surface of the first bead seat. The outer circumference of the outer rim is 23-25mm higher than the outer side of the second bead seat. Preferably, the widths of the two rims are respectively wider than the conventional width by 2 mm. The heightened and widened rims on both sides not only increase the strength, but also greatly improve the protection of the tires. Poor driving requirements for cargo vehicles.
