The invention provides a railway ballastless track stable walking tricycle tire which is characterized by comprising a body with a cavity in the middle, the body comprises an inner side tire part and an outer side tire part, the outer diameter of the outer side tire part is smaller than that of the inner side tire part, and a positioning step is formed between the outer side tire part and the inner side tire part; a plurality of convex patterns are arranged on the outer circumferential surface of the outer tire part, and guide slopes are formed on the two sides of the convex patterns respectively, so that a splayed structure is formed between every two adjacent convex patterns. The positioning step is formed between the outer tire part and the inner tire part of the tire body, so that the tire can be effectively ensured to stably walk on a ballastless track of a railway, when the tire walks, the convex pattern part utilizes a guide slope with a smaller gradient as a buffer, and two adjacent convex patterns can form a height difference compensation effect, so that the stability of the tire is improved. The tires gradually pass through the sleeper base exposed platform with the large height difference, the walking stability of the tires on the double-block type sleeper is greatly improved, and the double-block type sleeper can be suitable for different types of plate type ballastless track beds.
本发明创造提供了一种铁路无砟轨道稳定行走的三轮车轮胎,其特征在于:包括中部设有空腔的本体,本体包括内侧胎部和外侧胎部,外侧胎部外径小于内侧胎部外径,二者间形成定位台阶;外侧胎部外圆周面设有若干外凸花纹,外凸花纹两侧分别形成引导坡,使得每两相邻的外凸花纹间均形成“八”字形结构。本发明创造轮胎的本体外侧胎部与内侧胎部间形成定位台阶,可有效保证轮胎稳定行走于铁路无砟轨道,轮胎行走时,外凸花纹部分利用坡度较小的引坡作为缓冲,相邻两外凸花纹能够形成高差补偿作用,使轮胎逐渐通过高差较大的轨枕基座外露平台,大幅提高轮胎较为在双块式轨枕上行走的稳定性,可适用于不同型式的板式无砟道床。
