The invention discloses an externally-arranged tire pressure-monitoring, shock-absorption and noise-reduction elastic wheel. The wheel comprises a tire and a hub; an air storage chamber is formed between the tire and the hub; an air pressure monitoring annular groove is formed in the center of the outer end face of the hub; the spokes of the hub are provided with connecting air passages; two endsof each connecting air passage are respectively communicated with the air storage chamber and the air pressure monitoring annular groove; the wheel further comprises a tire pressure monitoring deviceand an air inlet valve; the tire pressure monitoring device is embedded in the top of the air pressure monitoring annular groove; a monitoring air chamber is formed between the tire pressure monitoring device and the air pressure monitoring annular groove; one end of the air inlet valve penetrates through the center of the tire pressure monitoring device and then is in threaded connection with thebottom center of the air pressure monitoring annular groove and presses and fixes the tire pressure monitoring device onto the hub; air outlet holes are evenly distributed in the bottom of the innercavity of the air inlet valve. According to the elastic wheel, the connecting air passages are arranged in the spokes of the hub so as to be communicated with the air storage chamber and the monitoring air chamber, so that the mounting position of the tire pressure monitoring device is moved outwards, and therefore, a centrifugal force borne by the tire pressure monitoring device is reduced, tirepressure monitoring precision is higher, and the service life of the monitoring device is longer.
本发明公开了一种外置式胎压监测的减震降噪弹性车轮,包括轮胎和轮毂,轮胎与轮毂之间形成有储气室,轮毂外端面的中心设有气压监测环形槽,轮毂的辐条设有连接气道,连接气道的两端分别与储气室和气压监测环形槽连通,还包括胎压监测装置和进气阀,胎压监测装置套嵌在气压监测环形槽的顶部,并与气压监测环形槽之间形成监测气室,进气阀的一端穿过胎压监测装置的中心后螺纹连接在气压监测环形槽的底部中心,并将胎压监测装置压紧固定在轮毂上,进气阀的内腔底部均布有出气孔;本发明通过将轮毂的辐条内设置连接气道,来贯通储气室与监测气室,实现胎压监测装置安装位置的外移,减小胎压监测装置所受的离心力,使胎压监测精度更高及监测装置使用寿命更长。
