Abstract

The utility model discloses a tubeless rim with a reinforced ring at the rim and a wheel, wherein the two axial ends of the rim are rims; the inner surface of the wheel rim is fixedly provided with a steel ring surrounding the inner surface circumference of the wheel rim, and the inner surface is one side surface of the wheel rim facing to the central axis of the wheel rim. The wheel comprises the tubeless rim with the rim provided with the reinforcing circular ring. The utility model discloses set firmly the steel ring around this rim inner face border in rim inboard, intensity (especially the weakest position) that can make the rim increase, prevent that the rim from producing plastic deformation under radial force, yawing force and stack alternating stress repetitive action and leading to unable the use.

Description

Tubeless rim with reinforcing ring at rim and wheel

Technical Field

The utility model relates to a wheel field of making especially relates to a rim area strengthens tubeless rim and wheel of ring.

Background

A wheel generally comprises a tyre mounted on a rim, a rim intended to be connected to an axle, spokes intended to connect the rim to the hub, and a hub. The mode that tubeless rim damaged includes that the rim warp and lead to inefficacy, the vehicle is at long-time driving in-process, often can brake under the operating mode of heavy load, scram or go at the highway section of undulation, the radial force of tire from the road surface transmission can turn and act on rim edge, and wheel hub also can be used in the rim through the axial force that superposes in addition, because the rim receives radial force, lateral force and superpose alternating stress, can produce plastic deformation and lead to the phenomenon that can't use under the effect of repeated atress many times in the weakest position of rim intensity.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rim area strengthens tubeless rim and wheel of ring, it has overcome in the background art the not enough of prior art.

The utility model provides a technical scheme that its technical problem adopted is:

a tubeless rim with a reinforced ring at the rim is characterized in that the two axial ends of the rim are rims; the inner surface of the wheel rim is fixedly provided with a steel ring surrounding the inner surface circumference of the wheel rim, and the inner surface is one side surface of the wheel rim facing to the central axis of the wheel rim.

In one embodiment: the steel ring is fixed with the inner surface of the wheel rim by welding.

In one embodiment: the section of the steel ring is circular.

A tubeless wheel comprises the tubeless rim with the reinforcing circular ring at the rim.

Compared with the background technology, the technical scheme has the following advantages:

there is the weakest position of rim intensity to above conventional tubeless wheel rim and begins to produce plastic deformation and lead to unable technical shortcoming of using, the utility model discloses the rim is for overcoming above defect, has set firmly the steel ring that encircles this rim inner face border at rim flange inboard, can make the intensity (especially weakest position) of rim flange increase, prevents that the rim flange from producing plastic deformation under radial force, yawing force and stack alternating stress repeated action and leading to unable the use.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Figure 1 is a cross-sectional view of a tubeless rim with a rim reinforcing ring.

Fig. 2 is a partial enlarged view a in fig. 1.

Figure 3 is a side view of a tubeless rim with a rim reinforcing ring.

Detailed Description

Referring to fig. 1 to 3, a tubeless rim with a reinforced ring at the rim has a rim 10 at both axial ends; a steel ring 20 surrounding the inner circumference of the rim 10 is fixed on the inner surface of the rim 10, which is a side surface of the rim 10 facing the central axis of the rim.

In this embodiment, the steel ring 20 is fixed to the inner surface of the rim 10 by welding, and the section of the steel ring 20 is circular. The steel ring 20 may be formed by rolling a steel rod and then welded to the inner surface of the rim.

The utility model discloses set firmly the steel ring around this rim inner face border in rim inboard, intensity (especially the weakest position) that can make the rim increase, prevent that the rim from producing plastic deformation under radial force, yawing force and stack alternating stress repetitive action and leading to unable the use.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
