Abstract

The utility model relates to a concave-shaped spoke steel ring with air holes. The concave-shaped spoke steel ring with the air holes comprises a spoke which is divided into an inner structure, a middle structure and an outer structure. The middle portion of the spoke is in a concave shape, axle holes used for installing vehicle axles in an inserting mode are formed in the inner portion of the spoke, screw holes used for installation and fixation are formed in the middle structure, and the air holes are formed in the outer structure. Crushing resistant performance of the steel ring is strengthened through change of the shape of the spoke, convenience of installation of an inflating valve is improved, and meanwhile the concave-shaped spoke steel ring with the air holes has the advantages of being low in cost, wide in using range, strong in practicality, and strong in crushing resistant performance.

Description

A kind of concavity spoke steel ring with the wind hole

Technical field

The utility model belongs to wheel accessory technical field, relates to a kind of concavity spoke steel ring with the wind hole.

Background technology

wheels of automobile generally is divided into tyre tube wheel and the large class of inner tube-free wheel two, wheel is comprised of steel ring and spoke, the steel ring appearance is equipped with tire, spoke and steel ring are welded together, spoke relies on bolt to connect together with axletree, inner tube-free wheel is compared with tyre tube wheel is arranged, because it is energy-conservation, the advantages such as safety have reached more than 95% in American-European countries's popularity rate, rapid growth along with China's economy, the increase year by year of express highway path mileage, inner tube-free wheel has tyre tube wheel with the speed of annual 30% left and right in replacement in China recent years, a large amount of uses along with inner tube-free wheel, but its some weakness also come out, because the wheel rim ratio of inner tube-free wheel has the tyre tube wheel wheel rim low, bead seat does not have the thick of the inner tube of a tyre, width is narrower, therefore its flexural strength is lower, like this in the situation that turn inside diameter or meet slightly large, the power that passes to wheel rim flange ring due to tire is very large, just be easy to cause bottom land to arrive this section distortion on little limit, place, disc wind hole buckles, or break apart, cause the situation such as disappointing to happen occasionally, user's complaint, bring certain difficult problem for the use of inner tube-free wheel.

The utility model content

In order to overcome the above-mentioned shortcoming of prior art ,The utility model provide a kind of with low cost, practical, operating cycles is long and the concavity spoke steel ring with the wind hole of shape characteristics attractive in appearance.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of concavity spoke steel ring with the wind hole, comprise spoke, spoke is divided into interior China and foreign countries three coil structures, the middle part is matrix, inside is provided be used to the axis hole of assigning axletree, middle part one circle is provided with for fixing screw is installed, and the outer ring is provided with the wind hole.

The beneficial effects of the utility model are: strengthen the crushing resistance of steel ring by the shape that changes spoke, improved the facility of dress tire tube valve, have simultaneously characteristics with low cost, that use is extensive, practical, crushing resistance is strong.

In figure: 1-spoke, 2-axis hole, 3-screw, 4-wind hole.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Referring to Fig. 1 and Fig. 2, a kind of concavity spoke steel ring with the wind hole comprises spoke 1, spoke 1 is divided into interior China and foreign countries three coil structures, and the middle part is matrix, and inside is provided be used to the axis hole 2 of assigning axletree, middle part one circle is provided with for fixing screw 3 is installed, and the outer ring is provided with wind hole 4.

The beneficial effects of the utility model are: strengthen the crushing resistance of steel ring by the shape that changes spoke 1, improved the facility of dress tire tube valve, have simultaneously characteristics with low cost, that use is extensive, practical, crushing resistance is strong.

Claims

1. the concavity spoke steel ring with the wind hole, comprise spoke, it is characterized in that: spoke is divided into interior China and foreign countries three coil structures, and the middle part is matrix, and inside is provided be used to the axis hole of assigning axletree, and middle part one circle is provided with for fixing screw is installed, and the outer ring is provided with the wind hole.
