Description

Car tire safety device

Technical field

The present invention relates to an attachment for an automobile tire, and more particularly to a safety device for a tubeless automobile tire (commonly known as a "vacuum tire").

Background technique

When a car is in a high-speed driving process, if it encounters a sudden puncture, it will lead to rudder, rollover, and even corner.

A vicious accident in which a car crashed. For banknotes and military police vehicles, you cannot continue driving after a puncture, and you will recognize 1

Cause more serious secondary disasters. Application No. 02286169.6 "New Car Tyre Safety Device", Ben

And 200420087907.8 "Automobile tire safety device", discloses a safety device made of engineering plastic, inner and outer ring phase sleeve between the hub and the tire, wherein the inner ring is a full circle, and the outer ring is divided into radial Two sections, with two sets of bolts and nuts, connecting the two half rings into one outer ring. The connection method used, the former application is connected by bolts and nuts; the latter one is set between the inner and outer rings. There are guide grooves and rails, bolts and nuts are arranged in the slots, and the outer shape is a worm gear, which is placed in the worm gear box body, and both ends of the worm rod protrude out of the box, and are located in the above slots. In general, bolts and nuts are used to connect the outer rings that are broken down into two pieces. Obviously, in the narrow space inside the tire, when installing and disassembling, it is extremely inconvenient to disassemble the bolt and the nut in the circumferential direction. And it is extremely time consuming. Since the outer ring and the tire have a considerable radial distance, after the puncture, the rigid outer ring is directly crushed on the inner surface of the tire. Although it can continue to drive, the damage to the tire is still quite serious. , can't even be used anymore, and the sloshing vibration is large. Summary of the invention

The object of the present invention is to avoid the above-mentioned deficiencies of the prior art, and to provide a straight-line driving when a tubeless tire encounters a puncture accident, without rudder, side slip, rollover, and convenient use, A smooth, easy-to-assemble car tire safety device. The object of the present invention can be attained by the following measures - an automobile tire safety device, which is an inner support system device mounted on a hub in a tire, the inner side of which is adapted to the shape of the position mounted on the hub, The device is composed of a plurality of segments whose inner side surface and outer side surface are circular arc surfaces, and is combined into an integral ring. The cross section of the valve block is in the shape of "work", and the upper part, the lower part and the middle part of the "work" shape body are a vertical arc transition between the vertical portions, characterized in that the petals are combined into a circular ring, and have four, five, six and six or more segments, using a rigid metal material, Made of lightweight aluminum alloy, between each two pieces of the block, through the connection of each axial locking mechanism, the 4~6 segments or segments are combined into a ring; the ring is closely attached to the hub On the inner side surface, a lining sheet made of an elastomer material is attached, and a non-metallic object is attached to the outer side surface.

In the above axial locking mechanism, each of the two adjacent petals is locked and connected, and both sides of the valve are provided with protruding semi-protrusions, half of each side of the two petals The boss is combined into a boss, an axial screw hole is formed in the middle of the boss, and the outer surface of the boss is a cone surface; and a pressing screw with a bottom plate is passed through the screw hole, wherein the bottom plate is located at the boss a bottom portion, a concave surface having a conical surface, passing through the pressing screw, and overlying the above-mentioned combined boss, the inner cone surface of the pressing block is in contact with the outer cone surface of the boss, and is provided with a bottom plate The screw and the nut are tightened to lock, and each of the two petals is coupled by the locking of the two semi-protrusions on one side thereof.

At the inner side of each of the two ends of the block, there is a chamfered surface of 45° angle, and the joint of each of the two merged petals forms a notch angle α from the inner side toward the periphery of the axial locking mechanism. , the angle of the notch angle is 90°.

The non-metallic object on the outer side of the ring is a plastic or rubber strip which is covered with a raised rubber table.

Both ends of the above-mentioned plastic or rubber strip have a step-shaped connector, and a joint is formed at the joint. ' The safety device of the present invention has the following advantages:

1. The tubeless tire with the safety device of the present invention is installed, and the tire is bumped when the vehicle is running, which greatly reduces accidents such as steering, tilting, rollover, and rollover, and avoids car crash and can be saved. Valuable life is not in the test. The ring of the present invention is divided into 4~6 segments or a plurality of segments and then connected, and the radial height of the device can be increased to be close to the inner surface of the tire, especially the outer edge of the ring is covered with a rubberized table. Plastic or rubber strips, which can shorten the radial distance between the tires, reduce the line speed difference between the hub and the tire, and play a buffering role, even if the tire car can still maintain a straight line for more than tens of kilometers, and Do not grind tires. With the device of the present invention, the car can also eliminate the spare tire due to its safety.

2. Easy to assemble and disassemble, easy to use. The valves of the device are not connected by bolts and nuts from the circumferential direction, but are pressed by an axial locking mechanism, and only need to extend into the tire when disassembling, in a space of 90° notch angle The nut can be rotated and removed or installed in 5 to 10 minutes.

3. The locking device adopts the inner and outer cone surface phase sleeves, and uses the slope principle to increase the force to make the locking more secure.

4. The plastic or rubber strip on the outer edge of the device, as well as the misalignment of the outer strip, eliminates periodic vibrations during tire rotation. The frame of the device is an I-shaped steel frame, which is strong and more durable than the one made of engineering plastics.

The invention is further described in the following with reference to the accompanying drawings and embodiments.
