Problems solved by technology

[0003] At present, the self-parking recreational vehicle is usually a two-wheeled vehicle structure, and the stability of the tires in a straight line is relatively high. Often, the matching tires are used such as figure 1 The tire with high longitudinal tread groove shown in the figure, this groove can exert excellent straight-forward stability when the tire is running straight, but the gripping ability of this kind of tire is limited, and the parking distance of the vehicle will be longer, which affects the The parking brake performance of the overall vehicle, and it is also prone to dumping when parking, which affects the parking performance of the vehicle
In addition, in order to improve the parking braking performance of the vehicle, it is usually equipped with tires with a larger section width, which can properly prevent the vehicle from tipping over, but it will increase the weight of the tire, which will affect the parking ability of the vehicle. Therefore, the general inflation When the tire is installed on the self-parking vehicle, it cannot meet the requirements of straight-line driving stability and parking braking performance at the same time

Embodiment 1

[0031] see Figure 2-Figure 8 Shown is the first embodiment of the tread pattern structure of the self-parking pneumatic tire of the present invention. The tire tread is composed of a plurality of closed annular main grooves 10 and a plurality of inclined auxiliary grooves 20 .

[0032] The transverse direction of the tire is the axial direction of the tire, the longitudinal direction of the tire is the circumferential direction of the tire, the center line of the tire longitudinal direction is the equator line CL of the tire, the inner side is close to the equator line CL, and the outer side is far away from the equator line CL, perpendicular to the tire The direction of the equator line CL is the radial direction of the tire.

[0033] The closed annular main groove 10 is centered on the tire equator line CL, and is distributed along the tire circumferential direction at intervals, and every two closed annular main grooves 10 adjacent to each other along the tire circumferent...

Embodiment 2

[0052] see Figure 9 Shown is the second embodiment of the tread pattern structure of the self-parking pneumatic tire of the present invention. Compared with Embodiment 1, the structure of Embodiment 2 is relatively simple, and the tire tread is composed of a plurality of closed annular main grooves. 10 and a plurality of inclined secondary grooves 20.

[0053] The transverse direction of the tire is the axial direction of the tire, the longitudinal direction of the tire is the circumferential direction of the tire, the center line of the tire longitudinal direction is the equator line CL of the tire, the inner side is close to the equator line CL, and the outer side is far away from the equator line CL, perpendicular to the tire The direction of the equator line CL is the radial direction of the tire.

[0054] The closed annular main groove 10 is centered on the tire equator line CL, and is distributed along the tire circumferential direction at intervals, and every two clos...

Abstract

The invention discloses a pneumatic tire tread pattern structure for a self-parking vehicle, and relates to the technical field of tires, the pneumatic tire tread pattern structure comprises a plurality of closed annular main grooves and a plurality of inclined auxiliary grooves, the closed annular main grooves are distributed at intervals along the circumferential direction of the tire by taking the equatorial line of the tire as the center, every two adjacent closed annular main grooves along the circumferential direction of the tire are in a central symmetry pattern, the inclined auxiliary grooves are formed in the left side and the right side of the equatorial line of the tire in parallel at equal intervals in the circumferential direction of the tire, the inclined auxiliary grooves are located between the closed annular main grooves, every two adjacent inclined auxiliary grooves in the inclined auxiliary grooves on the left side and the right side are located on the same straight line, and each closed annular main groove is composed of a head edge, a tail edge and a center block. The head edge extends in the circumferential direction of the tire, the tail edge obliquely extends in the axial direction of the tire, and the head edge is connected with the tail edge. After the technical scheme is adopted, the pneumatic tire tread pattern structure for the self-parking vehicle can ensure the straight advancing performance of the tire and improve the parking braking performance of the tire.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a tread pattern structure of a pneumatic tire for self-parking. Background technique [0002] In recent years, the domestic leisure vehicle market has developed rapidly, especially recreational vehicles have been vigorously developed. Consumers are paying more and more attention to the convenience of vehicle use, especially the convenience of vehicle parking. Thereby the recreational vehicle that can realize self-parking function becomes the new trend of market development. Recreational vehicles often adopt a vehicle structure with front and rear wheels. When this type of vehicle is parked, additional parking accessories must be installed to prevent the vehicle from toppling over. However, adding parking accessories will increase the weight of the vehicle, thereby affecting the convenience of parking the vehicle. Therefore supporting the tire that can realize self-parking become...
