Described sealing pneumatic tyre is connected to the tire pressure monitoring unit that stretches out fuel tank epicoele A top.
Described sealing pneumatic tyre is connected to the safety valve that stretches out fuel tank epicoele A top.
The fixing inner top that inserts " U " shape case of described electric air pump suction port, case top seal lower openings is led to atmosphere.
The utility model can reach following good effect after adopting said structure: becoming lubricant pump filler opening suction grease is main oil-feed mode into main oil-feed mode for the powerful grease that is pressed into, guarantee that the oil-feed of lubricant pump filler opening is abundant, have the pumping grease ability more much higher than existing product, even under certain low temperature and lowpressure, also can pumping high viscosity grease, enlarged Applicable scope simultaneously.
