The invention discloses a directional flow guide device and a tire, and belongs to the technical field of tires. The directional flow guide device takes the tire pattern circumferential pitch number as a period in the circumferential direction of the tire, openings are sequentially formed in a tire tread combination area at the contact position of a tire crown and the ground to the edge of the groove along the tire tread, and the directional flow guide device extends to the bottom of the groove through the side wall of the groove; the tread combination area is of a combined structure of a slit and an inclined surface extending towards the edge, and the cut-off part of the side wall is in a closed state; and the directional flow guiding device main body inclines from the cut-off position of the tread and the side wall to the edge part until the edge part is a maximum opening to form a wedge-shaped structure. The directional flow guide device is applied to tires, solves the technical problem that optimization of wet skid performance through pattern design has many limitations, can realize a directional drainage function, accelerates drainage of accumulated water in a contact area between a road surface and a tread, effectively optimizes the critical adhesion ability of the tire on the road surface on the premise of not losing other properties of the tire, and improves the control performance of the wet pavement.

    本发明公开了一种定向导流装置及轮胎,属于轮胎技术领域。该定向导流装置沿轮胎周向以轮胎花纹周节数为周期,由胎冠与地面接触位置的胎面组合区依次沿胎面向沟槽的边缘开口,通过沟槽的侧壁向沟槽底部延伸;胎面组合区为狭缝与向边缘延伸的斜面组合结构,侧壁截止处为闭合状态;定向导流装置主体由胎面和侧壁的截止位置向缘部倾斜,直至边缘处为最大开口形成楔形结构。本发明应用于轮胎方面,解决了现有通过花纹设计而优化湿滑性能具有诸多限制的技术问题,具有能够实现定向排水功能,加快路面与胎面接触区积水的排出,在不损失轮胎其他性能的前提下,有效优化轮胎在路面上的临界附着能力,提高湿路面的操控性能的特点。
