Abstract
Description
Technical Field
[0001] This utility model relates to the field of tires, and in particular to a tread pattern for a three-wheeled vehicle tire that combines wear resistance and traction performance. Background Technology
[0002] Current problems with tricycle tires during actual use:
[0003] 1. As the most common means of carrying goods, tricycles are increasingly in demand for high load capacity. As the load capacity of vehicles increases, the wear resistance of tires gradually decreases.
[0004] 2. The road conditions for tricycle use include not only paved roads, but also many hard mud or muddy roads, gravel roads, and even various mountain roads. Conventional tricycle tires are often gradually phased out by consumers due to insufficient traction performance when driving on unpaved roads. Utility Model Content
[0005] The purpose of this invention is to design a tread pattern for a tricycle tire that combines wear resistance and traction performance in order to solve the above problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] This utility model provides a three-wheeled vehicle tire tread pattern that combines wear resistance and traction performance. The tire has a central continuous tread block in the center and a shoulder tread block near the shoulder. A reinforced traction groove is provided between the central continuous tread block and the shoulder tread block. A reinforcing rib is below the reinforced traction groove. A circumferential traction groove and a radial traction groove are provided on the outer edge of the shoulder tread block. A main traction groove is provided between the shoulder tread blocks. The main traction groove extends from the shoulder to the central continuous tread block and gradually narrows from wide to narrow, connecting with the reinforced traction groove.
[0008] As a preferred embodiment of this utility model, the central continuous tread block is a longitudinal tread, and the ground contact width B of the central continuous tread block is 50-55% of the total tire travel surface width A.
[0009] As a preferred embodiment of this utility model, the shoulder tread block is a transverse tread pattern, and its width C is not less than the width D of the central continuous tread block. The width D of the central continuous tread block is designed to be 25-30% of the width A of the entire tire tread surface.
[0010] As a preferred embodiment of this invention, the total area of the central continuous pattern block and the shoulder pattern block is 55-65% of the total area of the patterned driving surface.
[0011] As a preferred embodiment of this utility model, the width G of the reinforced traction groove is 5-7mm, the depth h of the reinforced traction groove is 50% of the depth H of the main traction groove, and the height of the reinforcing rib is Hh.
[0012] As a preferred embodiment of this utility model, the width J of the circumferential traction groove is 3.0±1.0mm.
[0013] As a preferred embodiment of this invention, the radial traction groove width F is not less than 60% of the shoulder pattern block width C.
[0014] As a preferred embodiment of this utility model, the width E of the main traction groove is 70-90% of the width C of the shoulder tread block, and the draft angle of the main traction groove (i.e., the angle of inclination with the longitudinal center line of the tread) is designed to be two angles, namely, the draft angle between the main traction groove and the lower shoulder tread block is 12-15°, and the draft angle between the main traction groove and the upper shoulder tread block is 15-18°.
[0015] The beneficial effects of this utility model are as follows: by combining longitudinal and transverse patterns in a mixed pattern design, and using different traction grooves in different parts of the pattern, a three-wheeled tire that balances wear resistance and traction performance is achieved.
