The invention belongs to the technical field of tire groove structures, and particularly relates to a tread groove structure and a tire. The tread groove structure comprises a tire tread and grooves formed in the tire tread, the grooves comprise a first groove, a second groove and a stone discharging groove, the first groove is connected with the second groove through the stone discharging groove,and the width and the groove depth of the first groove are smaller than those of the second groove. The tread groove structure is provided with the stone discharging groove, pattern grooves are widened, the stone discharging groove is enlarged and widened, the widened and enlarged stone discharging groove can effectively prevent stones from being added, after a main groove is divided into two parts, the stones are difficult to add into the first groove due to the fact that the pattern grooves are narrow, and after the stones are clamped in the second grooves, the stones cannot be clamped dueto the fact that the stone discharging groove in one side has a good deformation capacity, and the stones can be thrown out rapidly in a driving process. Compared with a common pattern groove, by using the structure and the tire of the invention, stone removing performance, heat dissipation performance, anti-sideslip performance and wear-resisting performance are better.
本发明属于轮胎沟槽结构技术领域,具体涉及一种胎面沟槽结构及轮胎。本发明的胎面沟槽结构,包括轮胎胎面以及设置在轮胎胎面上的沟槽,所述沟槽包括第一沟槽、第二沟槽和排石槽,所述第一沟槽通过排石槽与第二沟槽连通,且第一沟槽的宽度及槽深均小于第二沟槽。本发明的胎面沟槽结构设置有排石槽,并加宽花纹沟、加大加宽排石槽,加宽加大的排石槽可以有效的避免石子的加入,将主沟一分为二后,第一沟槽由于花纹沟较窄很难加入石子,而第二沟槽夹入石子后由于一侧排石槽具有较好的形变能力,无法夹紧石子,可在行驶过程中快速将石子甩出。相比于普通的花纹沟槽,具有更好的排石性能、散热性能、防侧滑性能及耐磨性能。
