Description
The utility model relates to the automobile self-filler.
When automobile travels on highway; regular meeting runs into wherein tire flat; and can not start again; for running into such situation; except that managing to make trailer to leak gas car is dragged the scene away from or being stopped by the motorist oneself changes the tire; still there is not other emergency approach; and be trailer; might can't call for the moment, special on express highway long-time parking will cause the consequence of serious traffic congestion, at this moment; motorist's tire of having to do it yourself to change; the well-known tire that changes on express highway is quite dangerous, and thus, the person's that changes the tire life often is difficult to be protected.
The purpose of this utility model is to provide a kind of can the carrying out temporarily the automobile flat should acute inflation, so that maintenance point or the motor tire self-filler that sails out of the express highway dangerous area near automobile being sailed safely reach.
The utility model is to realize like this, the motor tire self-filler, comprise air pump, tracheae and check valve, installation shaft central airway by automobile front and back wheel independence cantilever of tracheae enters by encrypting the sealing ring-shaped air chamber that closure assemblies is formed between two antifriction-bearing boxs, enter atom tire inner chamber by the air flue in the vehicle wheel frame, the other end of tracheae and safety valve and air pump link, described pneumatic element, tracheae and lead all are fixed on the girder steel of car chassis with clip, and the circuit of system and automobile storage battery, source switch join.
Air flue in the described vehicle wheel frame, for the central airway of the radially air flue in the fin in the protruding and uniform spoke fin of vehicle wheel frame wheel hub and installation shaft constitute 90 ° crossing.
Wherein: system is one to the gas filed air pump of front and back tire.
Two air pump systems also can be arranged respectively to the front and back inflation of tire.
Effect of the present utility model is: simple to operate, only need press contactor, can put on the air to flat, because described pneumatic element, tracheae and lead all are fixed on the girder steel of car chassis with clip, the circuit of system and automobile storage battery, switch join, all sudden and violent heel exposes outside, and maintenance is also convenient.
The following drawings and embodiment will be described further technical characterictic of the present utility model:

Embodiment 1: as Fig. 1,2,4,5,6,7,8, shown in 9, it is the motor tire self-filler of an air pump system, comprise direct current air pump 115 (29), tracheae 114 (116), check valve 211, installation shaft central airway by independent cantilever 48 of tracheae 114 enters by encrypting the sealing ring-shaped air chamber that closure assemblies 43 (44) is formed between two antifriction-bearing boxs, enter atom tire 11 (16 by the air flue in the vehicle wheel frame 41,19,113) inner chamber, the other end of tracheae and safety valve 117 (210) and air pump 115 (29) link, described tracheae 16 one-way cocks 13 (14,18,111), pressure switch 12 (15,110,112) and lead all be fixed on the girder steel 118 of car chassis with clip, the circuit of system and automobile storage battery 28, switch 27 joins, air flue in the described vehicle wheel frame is as Fig. 5,8, the radially air flue 91 in 9 fins 92 that are depicted as in vehicle wheel frame hub flange and uniform spoke fin and the central airway 51 of installation shaft, 93 intersect 90 °.
Embodiment 2: as shown in Figure 3,, respectively be provided with its independent front-wheel safety valve 310 and trailing wheel safety valve 314 according to front and rear wheel air pressure difference, and front-wheel pressure switch 312, trailing wheel pressure switch 316, all the other are with embodiment 1.
Working process of the present utility model is: when the air pressure of a tire owing to gas leakage descends 15% the time, the baroswitch of this tire will be started working, the circuit contact of switch " led to " from " breaking " change make the inflation pump inflation of starting working, because there is difference of pressure in flat on two limit air flues of its check valve, make and be so incensed that to enter the tire of gas leakage by check valve, and constantly inflation, when the tire pressure of gas leakage rises to the upper limit operation pressure of baroswitch, baroswitch quits work, " broken " by " leading to " change in the contact of circuit, cut off the circuit of air pump and automobile storage battery, air pump just quits work.To an inflation of tire time, other three tires just can not produce the inflation phenomenon because there is not difference of pressure in their check valve tracheae two limits separately yet.If baroswitch is malfunctioning, the inflation that air pump is also keeping when getting to baroswitch upper pressure limit value, pressure will sharply rise, when pressure reaches safety-valve force value in the circuit, unnecessary gas will be put into atmosphere, make air flue keep certain atmospheric pressure value, at this moment the motorist just should know and sails to car nearby that maintenance station goes to keep in repair.
