Abstract
The utility model relates to a leakage warning device for automotive tyres, wherein, both ends of a power supply are provided with an air pressure warning lamp and a circuit detection switch which are respectively connected with a slip ring of a pneumatic electric converter; the pneumatic electric converter is installed on the fixed end of a half shaft of the tyre; the slip ring is provided with a carbon brush and connected with an air pressure control switch; a tyre valve is connected with the air pressure control switch through a connecting hose. The utility model is capable of detecting the tyre and warning at any time, has the advantages of simple structure and convenient installation, improves the safety for running and is suitable for being used for various vehicles.
Description
The utility model is the operating a kind of safety alarm device of full size vehicle, particularly the deflation warning system of motor tire in the highway communication transportation at present.
A up-to-standard chaufeur when steered wheel air pressure is on the low side under steam direction of passage dish and vision can feel, but load-carrying tire in rear portion can only lean on parking checking to find, these are conflicting with the modernization transportation, automobile travels on highway, especially on express highway, on the low side or when not having air pressure when tire pressure, the another of coordination adds heavy load at double, the major cause that Here it is blows out at turnpike driving, its consequence: one is that two tires are scrapped (explosion simultaneously, a stone roller is bad), the 2nd, pernicious traffic accident very easily takes place, in fact it is many more by the number of times of curb parking inspection that vehicle departs from the normal row track, and the possibility of being got rid of the foreign material bundle tire that falls in driving a vehicle is big more.
The purpose of this utility model is to overcome the deficiency that prior art exists, thereby a kind of safe and reliable, vehicle tire leakage alarm device of being convenient to install is provided.
The purpose of this utility model realizes by the following method.
This device is made up of power supply (1), air pressure alarm lamp (2), electric circuit inspection switch (3), trace (4) and pneumatic-to-current converter (9).Power supply (1) both positive and negative polarity connects air pressure alarm lamp (2) and electric circuit inspection switch (3) respectively, wherein air pressure alarm lamp (2) is connected the interior slip ring (5) of pneumatic-to-current converter (9) by trace (4) respectively with electric circuit inspection switch (3), pneumatic-to-current converter (9) is installed on tire semiaxis fixed end, rotate synchronously with vehicle tyre, slip ring (5) is enclosed within on the output shaft (7), have a carbon brush (6) on it and link to each other with baroswitch (11), tire valve (8) links to each other with baroswitch (11) by connection hose (10).
Principle of work:
This device is the normal barometric pressure with tire, by connection hose, is delivered in the pneumatic-to-current converter, changes by pneumoelectric transition components supervision tire pressure, and becomes electric signal and pass in the vehicle body operator's compartment by trace, reaches the functional requirement of this device.
When tire pressure drops to specified value, the automatic conducting of baroswitch, operator's compartment air pressure warning light is bright.The electric circuit inspection switch is a kind of accessory device that detects the deflation warning system circuit: can be switched on or switched off at any time in travelling, preventative testing circuit mode of operation, for example:
When 1, connecting, the air pressure warning light is bright, goes out during disconnection, proves that circuit, gas circuit are all normal.
The air pressure warning light does not work when 2, connecting, and proves: circuit breaker or alarm bulb damage.
The air pressure warning light is bright when 3, disconnecting, and prove: 1) warning light is with back segment circuit bonding.2) baroswitch damages short circuit.3) tire or connection hose gas leakage, air pressure are lower than specified value.
The utility model compared with prior art has following advantage:
1, vehicle after tire pressure drops to certain numerical value, has the bright or buzzer sound of warning light in the operator's compartment under the cruising state, and chaufeur can be grasped the low tyre situation at any time in operator's compartment, so as proper operation, the protection tire.
2, not all can normally use by the influence of weather, road conditions, when this device joint takes place by slight the leakage, report to the police immediately, reflection is sensitive.
3, Transmission is to turn round under no load condition substantially, so long service life.
4, other accessory attrition component all designs, maintains conveniently by national standard except that base part, and the dismounting tire is convenient, sturdy and durable, practical, and chaufeur all can be installed maintenance.
5, reduce the tire time of checking, guarantee traffic safety, cost-cutting improves conveying efficiency.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structure principle chart.
In Fig. 1: (1) power supply; (2) air pressure alarm lamp; (3) electric circuit inspection switch; (4) trace; (5) slip ring; (6) carbon brush; (7) output shaft; (8) tire tube valve; (9) pneumatic-to-current converter; (10) connection hose; (11) baroswitch.
The rotation of pneumatic-to-current converter (9) body skin, output shaft (7) maintains static, connection hose (10) is installed between the admission port of tire valve and pneumatic-to-current converter (9), tire pressure is passed to conv, flexible pipe can independently be installed, when running into extraordinary circumstances and pulling down, do not influence that tire is normal to be used and the conv running.
Should note during application maintenance:
(1) connect before, first energized, bright as the detection alarm lamp, illustrate that testing circuit is normal, alarm lamp promptly goes out by (joint have slight leakage gas warning lamp promptly bright) behind the connection flexible pipe, checks the mode of operation of pneumatic-to-current converter with this.
(2) adaptor union is avoided contacting to earth, and prevents to stop up pore.
When last is buckled with slight gas leakage when (3) connecting, tries one's best and tighten fast.
(4) tire tube valve side hand-tight make-up air tight after, with spanner tighten again one the circle get final product, transducer side screws up with a wrench and gets final product.
(5) to check seal ring before the installation, find to damage in time and change that connection hose is flexible, mustn't twist.
Claims (1)
- A kind of vehicle tire leakage alarm device, by power supply (1), air pressure alarm lamp (2), electric circuit inspection switch (3), trace (4) and pneumatic-to-current converter (9) are formed, power supply (1) both positive and negative polarity connects air pressure alarm lamp (2) and electric circuit inspection switch (3) respectively, it is characterized in that: air pressure alarm lamp (2) is connected the interior slip ring (5) of pneumatic-to-current converter (9) by trace (4) respectively with electric circuit inspection switch (3), pneumatic-to-current converter (9) is installed on tire semiaxis fixed end, rotate synchronously with vehicle tyre, slip ring (5) is enclosed within on the output shaft (7), have a carbon brush (6) on it and link to each other with baroswitch (11), tire valve (8) links to each other with baroswitch (11) by connection hose (10).
