Description

Technical Field

[0001] The utility model belongs to the technical field of tires, and in particular relates to a tread pattern of an all-steel load-bearing radial tire for a tugboat and a tire. Background Art

[0002] The automotive industry and logistics market continue to maintain rapid development, prompting the automobile body and trailer manufacturing industry to continue to maintain a rapid development trend; the growing prosperity of my country's maritime, road freight and container transportation markets has also led to an increase in demand for semi-trailers. The broad market prospects of China's semi-trailer industry will become increasingly prominent in the next few years.

[0003] Trailers and semi-trailers are characterized by being self-powered, independently loaded, and driven by other vehicles. Trailers, due to their design and technical characteristics, require towing by a vehicle for proper operation. They are unpowered road vehicles used for transporting people or cargo. Because trailers are unpowered, their tires do not steer or drive, serving primarily as load-carrying vehicles. Trailer tires typically have a forward tread pattern, which reduces driving resistance. Lower rolling resistance helps conserve fuel. A forward tread pattern also effectively prevents skidding and even tailspinning at high speeds, especially around corners. However, a forward tread pattern can lead to insufficient grip during starting and excessive braking distances.

[0004] Currently, to enhance tire grip, numerous steel plates are typically placed on the tire surface. While this significantly increases tire grip, it also significantly reduces tire wear resistance. Furthermore, because trailers and semi-trailers frequently turn at high speeds, excessive steel plates on the tread surface can easily cause uneven wear. Tires with uneven wear are prone to unexpected events, such as blowouts caused by uneven forces due to impacts, posing a significant threat to the safety of drivers and passengers. Therefore, those skilled in the art need to provide a new tire suitable for use on trailer tugboats. Utility Model Content

[0005] The details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects, and advantages of the present application more readily apparent.

[0006] The utility model provides a tread pattern and a tire of an all-steel load-bearing radial tire for a tugboat, which solves the technical problem in existing trailer tires that excessive steel sheets on the tread significantly reduce the wear resistance of the tire, easily causing uneven wear and affecting driving safety. The utility model is suitable for trailer tugboats, avoids abnormal wear of the tugboat tires due to frequent vehicle steering, can effectively extend the service life, and improve driving safety.

[0007] The utility model discloses, on one hand, a tread pattern of an all-steel load-bearing radial tire for tugboats, comprising a plurality of longitudinal main grooves extending circumferentially along the tread and a plurality of pattern blocks separated by the longitudinal main grooves. The pattern blocks include a central pattern block arranged along the circumferential centerline of the tread, middle pattern blocks located on either side of the central pattern block, and side pattern blocks located outside the middle pattern block. The area ratio of the middle pattern blocks to the central pattern blocks is (0.95-1.10):1, and the area ratio of the side pattern blocks to the central pattern blocks is (1.25-1.4):1. The small difference in area between the middle pattern blocks and the central pattern blocks ensures uniform force in the core area where the tire contacts the ground. The larger area of the side pattern blocks compared to the other pattern blocks improves tire shoulder stability and prevents abnormal wear of the tugboat tire due to frequent vehicle steering.

[0008] In some embodiments, the central tread block is provided with a central steel plate. The central steel plate includes a first central steel plate and a second central steel plate arranged alternately, with the first and second central steel plates forming a trumpet-shaped structure. The provision of the central steel plate can better prevent abnormal wear on both sides of the steel plate, improve the tire's grip on the road, and enhance the vehicle's handling performance during high-speed driving.

[0009] In some embodiments, the central tread blocks are provided with central steel plates, comprising first and second central steel plates arranged alternately, the first central steel plates being collinear with the first central steel plate, and the second central steel plates being collinear with the second central steel plate. The provision of the central steel plates can better prevent abnormal wear on both sides of the steel plates, improve the tire's grip on the road, and enhance the vehicle's handling performance during high-speed driving.

[0010] In some embodiments, the central steel sheet has a wavy structure and is disposed throughout the central pattern block.

[0011] In some embodiments, the middle steel sheet has a wavy structure and is arranged through the middle pattern block.

[0012] In some embodiments, multiple grooves are spaced apart on both shoulders of the tire, each having a rounded square structure. The groove structure can increase the heat dissipation area, improve the heat dissipation efficiency of the shoulder, and reduce the occurrence of shoulder voids and other problems.

[0013] In some embodiments, a plurality of shoulder steel sheets are arranged in parallel between adjacent grooves.

[0014] In some embodiments, the bottom of the longitudinal main groove is a broken line structure, and the groove wall of the longitudinal main groove adopts a four-sided gemstone structure. This longitudinal main groove structure effectively prevents damage to the groove bottom from sharp objects such as road stones when the vehicle is traveling at high speed, while also improving product recognition and aesthetics.

[0015] In some embodiments, the distance from the vertex of the four-sided gemstone-shaped structure to the bottom of the longitudinal main groove is 1 / 2 to 4 / 5 of the depth of the longitudinal main groove.

[0016] Another aspect of the present invention provides a tire having a tread pattern of any of the above-mentioned all-steel load-bearing radial tires for tugboats.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) The tread pattern of the all-steel load-bearing radial tire for tugboats of the present invention is composed of five pattern blocks divided by four longitudinal pattern grooves. The area difference between the middle pattern block and the central pattern block is small, which can ensure that the core area of the tire contacting the ground is evenly stressed. The area of the side pattern blocks is larger than that of other pattern blocks, which can improve the stability of the tire shoulder and avoid abnormal wear of the tugboat tire due to frequent vehicle turning.

[0019] (2) The central and middle tread blocks of the all-steel load-bearing radial tire for tugboats of the present invention are both provided with wavy steel sheets, which can better avoid abnormal wear on both sides of the steel sheets, improve the grip of the tire surface on the road, and enhance the handling performance of the vehicle during high-speed driving; no steel sheets are provided on the edge tread blocks on both sides of the tread, which helps to avoid excessive wear of the shoulders of the tugboat tire due to frequent steering of the vehicle and uneven wear.

[0020] (3) The tread pattern of the all-steel load-bearing radial tire for tugboats of the present invention is provided with multiple grooves and shoulder steel sheets at intervals on both sides of the tire shoulders, which can increase the heat dissipation area, improve the heat dissipation efficiency of the shoulders, reduce the occurrence of shoulder voids and other problems, and improve the safety of the tire.

[0021] (4) The bottom of the longitudinal main groove of the tread pattern of the all-steel load-bearing radial tire for tugboats of the present invention is a broken line structure, and the groove wall adopts a four-sided gem-shaped structure, which can effectively prevent the damage to the groove bottom of the pattern by sharp objects such as stones on the road when the vehicle is traveling at high speed, and at the same time improve the product recognition and aesthetics.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "upper", "lower", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", and "third" may explicitly or implicitly include one or more of such features. The term "longitudinal" refers to the direction in which the tire rolls; the term "transverse" refers to the direction perpendicular to the mid-plane of the tire.

[0028] The embodiment of the utility model provides a tread pattern of an all-steel load-bearing radial tire and a tire for a tugboat. Figure 1 The figure is a schematic diagram of the tread pattern of a full steel load-bearing radial tire for tugboats according to an embodiment of the present invention. Figure 1As shown, the tread pattern of this all-steel radial tire for tugboats includes at least: a plurality of longitudinal main grooves 1 extending along the circumferential direction of the tread and a plurality of pattern blocks separated by the longitudinal main grooves 1. The pattern blocks include a central pattern block 2 arranged along the circumferential centerline of the tread, middle pattern blocks 3 located on either side of the central pattern block 2, and side pattern blocks 4 located outside the central pattern block 3. The area ratio of the middle pattern block 3 to the central pattern block 2 is (0.95-1.10):1, and the area ratio of the side pattern block 4 to the central pattern block 2 is (1.25-1.4):1. The small difference in area between the middle pattern block 3 and the central pattern block 2 ensures uniform force in the core area where the tire contacts the ground. The larger area of the side pattern block 4 compared to the other pattern blocks can improve tire shoulder stability and prevent abnormal wear of the tugboat tire due to frequent vehicle steering.

[0029] To improve the tire's grip on the road and enhance the vehicle's handling performance during high-speed driving, the central tread block 2 and the middle tread block 3 are both equipped with wavy steel plates. Compared with straight steel plates, wavy steel plates can better prevent abnormal wear on both sides of the steel plates. The central steel plates are provided through the central tread block 2 and include a first central steel plate 5 and a second central steel plate 6 arranged alternately, forming a trumpet-shaped structure. The middle steel plates are provided through the middle tread block 3 and include a first central steel plate 7 and a second central steel plate 8 arranged alternately, with the first central steel plate 7 and the first central steel plate 5 being collinear, and the second central steel plate 8 and the second central steel plate 6 being collinear. The steel plates on the tread blocks of the present invention form a continuous Z-shaped structure. There are no steel sheets on the edge pattern blocks 4 on both sides of the tread, which helps to prevent the tugboat tire from wearing out too quickly and causing uneven wear due to frequent vehicle turns.

[0030] Since a large amount of heat will accumulate on the shoulders of the tires due to long-term driving of the vehicle, in order to increase the heat dissipation area, improve the heat dissipation efficiency of the shoulders, reduce the occurrence of problems such as shoulder voids, and improve the safety of tire use, the present invention arranges multiple grooves 9 at intervals on the shoulders on both sides of the tire. The grooves 9 are a rounded square structure; multiple shoulder steel sheets 10 are arranged in parallel between adjacent grooves 9.

[0031] The longitudinal main grooves of this utility model are four straight grooves, which can ensure that the tug tire will not slip to the greatest extent when it is in a free rolling state, and at the same time ensure the drainage performance of the tire when it is driving on wet land. Figure 1 and Figure 2As shown, the bottom of the longitudinal main groove 1 is a broken-line structure, while the groove wall of the longitudinal main groove 1 adopts a four-sided gemstone-like three-dimensional structure, with the apex of the four-sided gemstone structure located on the groove wall of the longitudinal main groove 1. In a preferred embodiment, the distance L from the apex P of the four-sided gemstone structure to the bottom of the longitudinal main groove 1 is 1 / 2 to 4 / 5 of the depth of the longitudinal main groove 1, that is, the apex of the four-sided gemstone structure is located between 1 / 2 and 4 / 5 of the depth of the longitudinal main groove 1 of the tire tread. Because the tread depth of tires used for tugboats is relatively shallow, the longitudinal main groove 1 of the utility model, through the above-mentioned structural design, can effectively prevent damage to the groove bottom from sharp objects such as road stones during high-speed driving, while also improving the tire's product recognition and aesthetics.

[0032] The present invention also provides a tire having a tread pattern similar to any of the aforementioned all-steel radial tires for tugboats. This tire structure is suitable for use on trailer tugboats, preventing abnormal wear of the tugboat tires caused by frequent vehicle steering, effectively extending their service life and improving driving safety.

[0033] The above-described embodiments only express several implementation methods of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
