Abstract
The utility model discloses an improved detecting device for an automobile tyre, comprising a sealed pipe like a Chinese character 'gong'. The opening of the pipe is connected with the inflation pipe of the tyre together; both sides of the bottom of the pipe are respectively a piston, a spring device, and a variable resistor; the middle of the variable resistor is provided with a lapping sheet connected with the piston through a connecting rod; two lead wires of the variable resistor are connected with two round metal tracks, and the other end of each round metal track is respectively contacted with a carbon brush rod. The improved detecting device for an automobile tyre has compact structure, reasonable design, convenient use, and good effect.
Description
Affiliated technical field
The utility model relates to a kind of improvement of automotive tire detection apparatus, and it is mainly used in the detection automobile, and whether tractor tire exists gas leak phenomenon.
Technical background
The gas leakage of motor tire is a serious problem, there are many accidents to cause because of tire flat, people pay much attention to it, therefore constantly the someone proposes the improvement project of correlation technique, for example, Chinese patent CN99248000.0 number is to be fixed on the vehicle brake pallet dust guard about the bracket base that proposes this detector in " a kind of motor tire detector ", spring fore-set in support and the bracket base is embedded in together mutually, spring fore-set and retracing spring place in the spring perch, and arc-spark stand is made with insulating material.Can produce actuation of an alarm during the tire malfunction of this detector, but its complex structure, and result of use is poor.
Summary of the invention
Device of the present utility model is to utilize air pressure to promote piston motion, spur variable-resistance butt strip, variable-resistance resistance is changed, cause that the electric current of entire circuit changes, whether and its current value becomes certain proportionate relationship with atmospheric pressure value, can detect tire thus and leak air.
Task of the present utility model is to finish with following technical scheme, in a similar I shape pipe, form a sealed space, its opening and inflation of tire pipe are connected together, in the both sides, bottom of this similar I shape pipe is respectively a piston and spring installation and a variable resistance, be coupled to each other with a connecting rod between the butt strip in piston and the variable resistance, variable-resistance two leads are connected with two circular metal tracks, article two, the circular metal track contact with two carbon brush rod respectively, and the excellent pig-tail wire of carbon brush is connected with amperemeter/ammtr on the operator's compartment panel.When gas leakage takes place in automobile, the gaseous tension of piston the right cylinder is greater than the pressure in the tire, it can promote piston forward and move, piston draws variable-resistance butt strip by connecting rod and also moves forward, make variable-resistance change in resistance, the current value change of entire circuit like this, chaufeur are sitting in can find the tire phenomenon that whether leaks air in the operator's compartment.
The compact conformation of this automotive tire detection apparatus, reasonable in design, easy to use, can in time find the tire flat problem, the hidden danger that eliminating may have an accident.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the cutaway view of automotive tire detection apparatus of the present utility model.
Fig. 2 is a constructional drawing between automotive tire detection apparatus variable resistance lead of the present utility model and the ammeter.
Among the figure 1, similar I shape pipe, 2, opening, 3, piston and spring installation, 4, variable resistance, 5, butt strip, 6, connecting rod, 7, lead, 8, amperemeter/ammtr, 9, the circular metal track, 10, the carbon brush rod.
The specific embodiment
As can be seen from Figure 1, this improved automotive tire detection apparatus is the seal cavity that is made of a similar I shape pipe (1), and similar I shape pipe (1) is by metal, plastics or elastomeric material are made, the opening of pipe (2) is that the appendix with motor tire is linked together, in the both sides, bottom of similar I shape pipe (1) is respectively a piston and spring installation (3) and a variable resistance (4), there is a butt strip (5) centre of variable resistance (4), connect with a connecting rod (6) between butt strip (5) and the piston (3), the amperemeter (8) on drawing two leads (7) and be contained in the operator's compartment panel from variable resistance (4) is connected.Road as shown in Figure 2, article two, lead (7) connection is installed in vehicle tyre by the cover tire of this face of steel plate and two the circular metal tracks (9) between the wheel rim, two the carbon brush rods (10) that are installed on the dust boot on brake wheel limit contact with two circular metal tracks (9) respectively, they all are concentrically ringed, and the pig-tail wire of carbon brush rod (10) be with the operator's compartment panel on amperemeter/ammtr (8) bonded assembly.In case the tire generation gas leak phenomenon of automobile, the cylinder gas pressure on piston (3) the right is greater than the opening (2) of pipe and the pressure in the tire, it can promote piston (3) and move forward, driving butt strip (6) by connecting rod (6) travels forward, the resistance of variable resistance (4) is changed, the current value of connected amperemeter/ammtr changes, and whether leaks phenomenon thereby promptly can observe motor tire in operator's compartment.
Claims (2)
1, a kind of improved automotive tire detection apparatus, it is characterized in that: the seal cavity that it is made of a similar I shape pipe (1), the opening of pipe (2) is that the appendix with motor tire is connected together, a piston and spring installation (3) and a variable resistance (4) are arranged in the bottom of similar I shape pipe (1), there is a butt strip (5) centre of variable resistance (4), connect with a connecting rod (6) between butt strip (5) and the piston (3), two leads (7) of variable resistance (4) are and two circular metal tracks (9) bonded assembly, the other end at circular metal track (9) has two carbon brush rods (10) to contact with these two circular metal tracks (9) respectively, and the lead-in wire of these two carbon brush rods (10) is to be connected with amperemeter/ammtr (8) on the operator's compartment panel.
2, according to the improved type automotive tire detection apparatus of claim 1 defined, it is characterized in that: the similar I shape pipe of this leak free (1) is made with metal, plastics or rubber material.
