Description

[Detailed description of the invention] How to balance motor vehicle tires, balanced vehicle tires, and The present invention is directed to vehicle tires that require careful consideration, for example, if the tire is made of lead alloy. The tire rim is made of a balance material that is denser than the rubber material used. The present invention relates to a novel method for balancing vehicle tires with or without. Book The invention further provides a vehicle tire balanced by said novel method; Relates to vehicle tires which are to be balanced by a regular method.

Traditionally, automobile tires may be fixed to the rim of the wheel on which they are mounted. Alternatively, a balance body or a weight body, preferably made of lead, may be used. A balance has usually been achieved. (For example, U.S. Pat. No. 2,049,703, No. 3177039, No. 3495877, No. 3960409 and No. 43795 (see specification No. 96), such a heavy body is used during non-king or, for example, when When washing a vehicle whose wheels are balanced due to heavy objects using automatic car wash equipment. It can easily come off and require rebalancing of the wheel. vehicle ho Most of the causes of eel imbalance are usually caused by the tires, or often all of the causes are For example, in tires such as those in tires, the weight body may cause damage to the tire itself depending on the position of the weight body. To compensate for the relatively small centrifugal force effect experienced in the radial and inward direction of amount of balance weight body is required and therefore a small balance effect per unit of weight I can only get it. Usually most or most of the causes of vehicle wheel imbalance are caused by Since everything is in the tire itself, the balance weight body will only show a normal value or imbalance. Judging from the fact that it is mounted on a new wheel rim, it seems that the wheel has had its tires replaced. You will need to rebalance frequently.

Also, usually by grinding the rubber from the tire itself in the tire trend area, the vehicle It has been proposed to balance the wheels or tires. (For example, English (See National Patent No. 1407371). The material removed by this method is located at a relatively large radial distance from the center of the eel, where centrifugal It is clear that the effect of force is quite large at the position, but on the other hand, the density of tire rubber is much smaller than the density of the normal tire balance weight body, and the result is unsatisfactory. A large amount of rubber must be ground before a good balance is achieved.

The object of the invention is to eliminate to a considerable extent the drawbacks of conventional balancing methods. A new and improved type of material that uses a balanced or weighted body with a higher density than rubber. The goal is to provide a balanced method.

For this purpose, when balancing by methods of the kind mentioned in the introduction, According to the invention, it is proposed to adapt an object made of material to tire rubber. Book If the method of the invention is carried out, the balance body adapted to the tire rubber will be reliably attached to the tire rubber. This can be ensured by simple means. The balance body is in the tire Positioned on the radial outside of the rim, it does not balance the rim as in traditional methods. The balance effect per unit of weight is greater than when the body is attached. Usually a car Most or all of the causes of imbalance between both wheels are due to the tires. , if a good quality rim is used, a tire balanced according to the invention can be wheeled. Transfer from one wheel rim to another without rebalancing the wheels. It is possible to move it.

During tire manufacture or at a later stage, e.g. when the tire is balanced, pockets are A cut-shaped receptacle is formed in the tire and is necessary for balancing the tire. These balance body receptors are preferably filled with a quantity of balance material into the receptor. For example, the section may be used to mold a tire using a tire mold configured for the purpose of forming a receptacle. Therefore, it can be formed or by using heat or perforation after manufacturing. , may be formed into the tire by milling or other suitable techniques.

According to one embodiment of the invention, the balancing material is in a molten state when inserted into the receptacle. It may be cured within the receiving part.

For example, alloys with relatively low melting points, particularly lead alloys, can be used, which alloys The 0 selection is injected into a receptor, which is a hole in the rubber, where it solidifies and remains. Typically, the balance material is a liquid or pasty mixture of metal powder, especially powdered lead. and a curing/binding agent (the mixture may optionally be combined with the wheel rim). is inserted into a receptacle placed in the tire to balance the tire. It will be done.

According to another embodiment of the invention, the receptacle is a groove or channel extending around the outer periphery. is formed on the tire wall, and a string or band of balancing material of an appropriate length is placed in the receiving portion. A shaped body is fitted, thereby optionally holding the balun of the tire together with the rim associated with the tire. Take a step. The amount and length of balance material actually required and the circumference of the tire wall The position to be placed can be calculated using a conventional balance machine.

According to yet another embodiment of the invention, the holes located relatively close to the outer circumference of the tire A balancing material is placed in the hole where a row is formed and the presence of a balancing material is required for balance. inserted. It goes without saying that the receiving part and the balance body within the receiving part come into contact with the road surface. For example, since the balance body does not come into contact with the road surface, If available, the balancing body may be placed in a receptacle located in the area of the tire tread. However, it is preferable to form the receiving part in a thick part of the tire wall or in a bead in the outer circumferential direction. Delicious.

The above-mentioned receiving portion is formed on the tire wall or in the tread area of the tire. One advantage is obtained when it is formed around the entire tire in the thicker section.

The balance material receiver was placed at its entrance to prevent mud from entering the receiver. Preferably, it has a sealing means.

As mentioned above, the present invention also provides a balance wheel with or without a wheel rim. The vehicle tire has a ballast with a density higher than that of the tire rubber. The balanced tire of the present invention has an object made of rubber material, and the balanced tire of the present invention has an object made of rubber material. It is characterized by being located. At this point, the balance body is held securely. The balance body is a source of imbalance in vehicle wheels consisting of tires and rims. Wheel elements that are responsible for most or all of the factors, i.e. Therefore, the balance body has an excellent balance effect per unit of weight. This can be easily achieved. This usually results in wheel rebalancing. Tires can be moved from one rim to another without the need for conversion.

Finally, the invention also provides that by the method of the invention, as defined in the claims, Concerning vehicle tires with or without rims to be balanced. this These tires have grooves or channels extending around their circumference or rows arranged around their circumference. It has a balance material receiving part which is a hole. The receiving portion extends around the tire. One advantage is obtained when it is formed into a thicker section of ear rubber. The receptor is a tire placed at its inlet to prevent mud from entering the receptor before balancing the It may have a sealing means.
