The invention discloses a double-wheel type roller assembly with a cushioning function, which comprises a pair of rollers coaxially sleeved on a roller shaft, each roller consists of a hub, a tire and a bearing, the tire is arranged on the outer ring of the hub, the bearing is arranged on the inner ring of the hub, the inner ring of the bearing is in interference fit with a rubber bag with a hollow structure, an inner ring of the image capsule is in interference fit with the rolling shaft, a core pipe is embedded in an inner core of the rubber bag, a core hole communicated with an inner cavity of the rubber bag is formed in the portion, making contact with the rubber bag, of the pipe wall of the core pipe, and a relieving air bag is arranged in the center of the rolling wheel and connected with the core pipe. In this way, according to the double-wheel type rolling wheel assembly with the cushioning function, the rubber bag is additionally arranged between the bearing and the rolling shaft, impact force caused by vibration is transmitted to the relieving air bag, the relieving air bag absorbs the impact force in an elastic deformation mode, the load of the rolling shaft is greatly reduced, and the purpose of cushioning is effectively achieved.
本发明公开一种带有缓震功能的双轮式滚轮组件,包括一对同轴套接在滚轴上的滚轮,所述滚轮由轮毂、轮胎、轴承组成,所述轮毂的外圈设置轮胎,所述轮毂的内圈设置轴承,所述轴承内圈过盈配合有中空结构的像胶囊,所述像胶囊内圈过盈配合滚轴,所述像胶囊内芯埋设有芯管,所述芯管管壁与像胶囊接触的部分开设有连通像胶囊内腔的芯孔,所述滚轮中央设置有缓解气囊,所述缓解气囊与芯管连接。通过上述方式,本发明提供一种带有缓震功能的双轮式滚轮组件,在轴承和滚轴之间增加像胶囊,将震动造成的冲击力传递给缓解气囊,缓解气囊以弹性形变的方式吸收冲击力,极大降低滚轴的负载,有效实现缓震目的。
