Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tires, in particular to a tire with a snow warning mark. Background Art
[0002] As is known, my country's national standard stipulates that the tread wear limit of radial tires for passenger cars is 1.6mm, and requires tire companies to set wear marks on the longitudinal grooves of the crown in accordance with the standard. When the tire tread wears to the above limit, it reminds the driver to replace the tire in time.
[0003] As is well known, in addition to the above tread wear limit requirements, radial tires for snow use have special snow warning signs that are half the depth of the main groove of the tread. When the tire tread is worn to the above limit, it reminds the driver that the snow performance is lost and the tire should be replaced in time.
[0004] The traditional snow warning sign can only indicate the extreme wear condition of the tire. However, during the use of the tire, as the tire groove decreases, it cannot fully characterize the traction of the tire on the snowy road, and there is no warning sign on the tire about the gradual loss of snow performance. Therefore, it needs to be improved. Utility Model Content
[0005] The utility model aims to provide a tire with a snow warning mark, which solves the problem that the traditional tire lacks a warning mark about the gradual loss of snow performance.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tire with a snow warning sign, comprising a tread and two sidewalls formed around the tread on both sides, a warning sign is arranged in the area of the tread, the warning sign is composed of a pattern, letters or special characters, a sound insulation pad is bonded to the inner wall of the tread, and a plurality of pressure sensors are arranged inside the sound insulation pad.
[0007] Preferably, the warning marks are evenly distributed in N equal parts along the circumference of the tire, N≥4, and the distance from the edge of the pattern block is greater than 2mm. The setting of multiple warning marks can more accurately observe the wear degree of the tread 3.
[0008] Preferably, the side of the warning mark is perpendicular to the circumferential surface of the tire, so that the wear between the tread and the ground can be well expressed intuitively at the warning mark.
[0009] Preferably, the warning mark includes multiple depths, and the depth range is 1 / 8H to 1 / 2H+1, where H is the pattern depth. By setting multiple different depths, it is to ensure that the tire snow performance warning mark can achieve the warning effect and quantify the corresponding relationship between the snow performance loss and the mark.
[0010] Preferably, the pattern size L is 8-14 mm, K is 0.6-1.2 mm, R is 1-3 mm, and J is 1-2 mm. The size of the pattern can be specifically designed according to the diameter of different tires.
[0011] Preferably, a rubber clamp is fixedly connected to one side of the sound insulation pad close to the inner wall of the tread, and the rubber clamp is clamped with the tread. The setting of the rubber clamp can increase the bonding ability between the sound insulation pad and the tread.
[0012] The beneficial effects of the utility model are as follows:
[0013] The utility model arranges graphics and words of different depths on the crown of the tire. As the tire is used, the corresponding words and graphics will disappear, thereby representing the performance loss of the tire in the snow state, which is a snow warning mark.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4A tire with a snow warning sign includes a tread 3 and two sidewalls 2 formed around the tread 3 on both sides. The tread 3 is the contact portion between the tire and the road surface. A warning sign 1 is arranged in the area of the tread 3. The warning sign 1 is composed of a pattern, letters or special characters. The warning sign 1 is evenly distributed in N equal parts along the circumference of the tire, N ≥ 4, and the distance from the edge of the pattern block is > 2mm. The setting of multiple warning signs 1 can more accurately observe the degree of wear of the tread 3. The side of the warning sign 1 is perpendicular to the circumferential surface of the tire. In this way, the wear between the tread 3 and the ground can be well and intuitively expressed at the warning sign 1.
[0022] See also Figure 1-4 , the warning mark 1 includes multiple depths, and the depth range is 1 / 8H to 1 / 2H+1, where H is the pattern depth. By setting multiple different depths, it is to ensure that the tire snow performance warning mark 1 achieves the warning effect, and to quantify the corresponding relationship between the snow performance loss and the mark. The pattern size L is 8 to 14 mm; K is 0.6 to 1.2 mm, R is 1 to 3 mm, and J is 1 to 2 m. The size of the pattern can be designed more specifically according to the diameter of different tires.
[0023] See also Figure 5 A sound insulation pad 4 is bonded to the inner wall of the tread 3, and a plurality of pressure sensors 5 are arranged inside the sound insulation pad 4. A rubber clamp 6 is fixedly connected to the side of the sound insulation pad 4 close to the inner wall of the tread 3, and the rubber clamp 6 is clamped to the tread 3. By setting the rubber clamp 6, the bonding ability between the sound insulation pad 4 and the tread 3 can be increased.
[0024] The specific implementation process of the utility model is as follows: when in use, a circle of sound insulation pad 4 can be bonded to the inner wall of the tread 3, and a rubber clamp 6 is provided on the sound insulation pad 4, which can be inserted into the tread 3, and then it can be loaded and used normally. After the tread 3 contacts and rubs with the ground, the warning sign 1 will also rub synchronously, and then the degree of wear of the tire can be accurately judged according to the different pattern shapes formed after the friction.
[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
