The invention relates to a novel snowfield tire nail telescopic device which comprises anti-skid tire nails, rubber sealing rings, metal lock pins, sheet springs, spiral springs, traction electromagnets A, traction electromagnets B, control circuit boards, an annular power supply and a rubber outer tire. When the lower traction electromagnet B is not powered on and the left and right traction electromagnets A are powered on, the metal lock pin is opened, the antiskid tire nails stretch out under the tension of the spiral springs and reach the rubber sealing rings, the traction electromagnets Aare powered off, the metal lock pins are pressed into the fixing grooves of the antiskid tire nails, and at the moment, the tire becomes a snowfield tire with the antiskid tire nails; when the traction electromagnets A are powered on, the metal lock pins are opened, then the traction electromagnets B are powered on, the antiskid tire nails are attracted back to the spring holes, then the tractionelectromagnets A are powered off, the metal lock pins are inserted into the fixing grooves, the traction electromagnets B are powered off, and the tire becomes a common tire. The problem of normal and safe driving of vehicles under the road condition that ice and snow pavements and common pavements are frequently switched in winter can be solved.
本发明涉及一种新型雪地胎胎钉伸缩装置,包括防滑胎钉、橡胶密封圈、金属锁销、薄片弹簧、螺旋弹簧、牵引电磁铁A,牵引电磁铁B、控制电路板、环形电源和橡胶外胎。当下方牵引电磁铁B不通电,左右牵引电磁铁A通电时,金属锁销打开,防滑胎钉受螺旋弹簧的张力伸出,到达橡胶密封圈处时,牵引电磁铁A断电,金属锁销被压入防滑胎钉的固定槽中,此时轮胎变为带防滑胎钉的雪地胎;当牵引电磁铁A通电时,金属锁销打开,随后牵引电磁铁B通电,防滑胎钉被吸回至弹簧孔处,随后牵引电磁铁A断电,金属锁销插入固定槽,牵引电磁铁B断电,此时轮胎变为普通轮胎。可解决冬季车辆在冰雪路面和普通路面频繁切换的路况下正常安全行驶的问题。
