Abstract

The utility model relates to a steel ring with a concave spoke. The steel ring comprises the spoke which is divided into an inner ring structure, a middle ring structure and an outer ring structure. An axle hole for a car axle to be arranged and inserted in is formed in the inner ring. Threaded holes which are used for mounting and fixing are formed in the middle ring. Air holes are formed in the outer ring. The spoke is in a sunken shape from outside to inside. Through changes of the shape of the spoke, compression resistance of the steel ring is strengthened, and convenience of mounting an air valve is improved. Meanwhile, the steel ring with the concave spoke has the advantages of being low in cost, wide in application, strong in practicality and strong in compression resistance.

Description

A kind of steel ring with concavity spoke

Technical field

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

Background technology

Wheels of automobile generally is divided into tyre tube wheel and inner tube-free wheel two large classes, 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 year by year increase of express highway path mileage, inner tube-free wheel has tyre tube wheel with annual about 30% speed 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 at turn inside diameter or meet in the slightly large situation, because it is very large that tire passes to the power of wheel rim flange ring, just is 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 brings 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 have with low cost, practical, operating cycles is long and the steel ring with concavity spoke of shape characteristics attractive in appearance.

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

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.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model lateral plan.

Among the 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 specified.

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

The utility model has improved the facility of dress tire tube valve by the crushing resistance of the shape enhancing steel ring of change spoke, has simultaneously characteristics with low cost, that use is extensive, practical, crushing resistance is strong.

Claims

1. the steel ring with concavity spoke comprises spoke, it is characterized in that: spoke is divided into interior China and foreign countries three coil structures, inside is provided be used to the axis hole of assigning axletree, middle part one circle is provided be used to the screw that installs and fixes, and the outer ring is provided with the wind hole, and described spoke is that ecto-entad is recess.
