Abstract

The utility model relates to a tire trouble alarming device for a vehicle, which is suitable for various vehicles, is especially suitable for trucks and trailers, and is also used for tractors. The tire trouble alarming device for a vehicle is composed of a fixing bracket, a sensor and an alarming circuit which is provided with a relay, a lamp and a horn and is arranged in a steering room. The sensor is arranged on the fixing bracket by a position limiting device, and the fixing bracket is arranged at the inner side of a tire. When the tire has no air, or the air pressure of the tire is insufficient, the fastening screws of a wheel loosens and sheds, and the circuit generates troubles, the utility model can all alarm. The tire trouble alarming device for a vehicle has visual alarm signals, timely and accurate alarm.

Description

The motor tire fault alarm

The utility model is a kind of motor tire fault alarm, is applicable to various vehicles, is specially adapted to bogie and towed vehicle, also can be used for trac..

Tire flat or wheel holding screw are loosening easily to cause the tire infantile failure, and the lighter's tire is scrapped, and wheel nave lands the road surface is damaged, and weight person can make wheel break away from car body and cause beyond thought grave accident.At present, tire flat also there are not preventive preferably, could find during entirely with driver's driving experience and parking checking, so the traffic accident that tire fault causes happens occasionally, especially long-distance, load-carrying, the vehicle that travels continuously are owing to tire flat or the loosening accident that causes of wheel holding screw are of common occurrence.

In view of above-mentioned problems of the prior art, the purpose of this utility model is that a kind of motor tire fault alarm will be provided, can be in time when tire flat or wheel holding screw are loosening, report to the police exactly, thereby reduce traffic accident, support vehicles safe operation.

The utility model is realized by following proposal in order to achieve the above object:

This annunciator is made up of fixed mount, sensor and warning circuit three parts.Fixed mount is made up of channel 1, angle bar 2 and clevis bolt 3.Channel 1 is connected with one side of angle bar 2 is T-shaped, and the another side of angle bar 2 is connected with clevis bolt 3, constitutes one.What sensor adopted is the limiting device of band mallet bar, and limiting device 5 is contained on the channel 1.Warning circuit is made up of relay, indicator lamp and loudspeaker, is contained in the operator's compartment; Its connection: power outlet one end bonding, the other end and ignition lock join, one end of the other end of ignition lock and the coil of relay and relay contact joins, the other end and the test button of coil are joined, and the other end of button connects a connector, pegs graft with limiting device, limiting device is all connected, other end bonding, an end of the other end of relay contact and lamp and loudspeaker circuit parallel joins, the other end bonding of this circuit.

Adopt the annunciator of said structure to have following advantage:

This alarm designs is reasonable, and is simple in structure, easy to manufacture, easy for installation, cheap, alerting signal is directly perceived, light is arranged, sound equipment is arranged, show that simultaneously it is timely, accurate, reliable to report to the police, and can in time find tire fault, prolong tire life, reduce traffic accident, avoid unnecessary economic loss, the support vehicles safety traffic.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is overall structure of the present utility model and installation site scheme drawing

Fig. 2 is a front view of the present utility model

Fig. 3 is a lateral plan of the present utility model

Fig. 4 is a circuit diagram of the present utility model

In the accompanying drawing: the 1st, channel 2 is that angle bar 3 is that clevis bolt 4 is that hole 5 is that limiting device 6 is that wheel shaft 7 is tires

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this annunciator is made up of fixed mount, sensor and warning circuit three parts.

Fixed mount: form by channel 1, angle bar 2 and clevis bolt 3.Channel 1 is connected with one side of angle bar 2 is T-shaped, and two holes 4 are arranged on the another side of angle bar 2, and it is fastening that clevis bolt 3 strides across wheel shaft 6 patchholes 4 usefulness nuts, is connected with angle bar 2, constitutes an integral body.

Sensor: employing be the limiting device 5 of band mallet bar, be installed on the channel 1 of fixed mount, after its installation site should make fixed mount be contained on the wheel shaft, spacing mallet boom end was 150-200mm apart from ground.

Warning circuit: adopt sound and light alarm, be made up of relay, indicator lamp and loudspeaker, indicator lamp XD is a red bulb, and loudspeaker Y adopts direct current loudspeaker or other direct current sounding components, and this circuit is contained in the operator's compartment.

Power supply adopts the direct supply (gasoline car 12V, diesel-powered vehicle and trac. 24V) of vehicle self.Its connection: power outlet one end bonding, the other end is connected to engine ignition switch K, the end of the outlet of the ignition lock other end and relay J coil and relay normally closed contact JK joins, the other end outlet of relay J coil and test button AN one end join, the other end of button connects a connector CQ, with limiting device normally closed contact XK ₁An end peg graft XK ₁, XK ₂, XK ₃, XK ₄Series connection, XK ₄Other end bonding, an end of the other end of relay normally closed contact JK and lamp XD and loudspeaker y circuit parallel joins, the other end bonding of this circuit parallel.

Circuit working principle: ignition lock K closure, the relay J coil that is together in series, button AN, limiting device normally closed contact XK ₁, XK ₂, XK ₃, XK ₄Form C/LOOP by bonding and power supply, relay coil is by electric current, and relay normally closed contact JK moves, and has disconnected the current supply circuit of lamp and loudspeaker, and the part of reporting to the police is in wait state.Press the button AN, disconnect relay J, XK ₁, XK ₂, XK ₃, XK ₄C/LOOP, relay outage, coil discharges, relay normally closed contact JK closure, lamp and loudspeaker current supply circuit are linked up, red light is bright, loudspeaker ring, acousto-optic is reported to the police simultaneously.

During use, the fixed mount that installs limiting device is installed in the inboard of tire 7, is fixed on the wheel shaft 6, each tire inboard is all adorned one.During installation, clevis bolt 3 is striden across wheel shaft 6, in the patchhole 4, use nut fastening, linking together with angle bar 2 has promptly fixed.The fixed mount installation site should make spacing mallet bar parallel with the tire inboard, and distance between the two is 5-8mm.

Automobile does not have gas or air pressure when not enough when tire occurring in the process of moving, the position pressurized that contacts to earth of tire, tire protrudes to both sides, and projection promotes spacing mallet bar to the inside, make the normally closed contact action of limiting device, disconnect current supply circuit, the relay outage, coil discharges, relay normally closed contact closure, red light is bright, and loudspeaker ring, and submit to the driver and conductor to overhaul.In like manner, if wheel holding screw loose or dislocation occurs, or this circuit breaks down, and as poor contact of contacts, broken string etc., this annunciator all can be reported to the police.
