Abstract
Tyre deflation detector contains a detection box 1 which has a means of attachment to the underside of axles on towed or towing vehicles. The detection box in turn is connected through an electric cable to a warning console on the dashboard of the towing vehicle to inform driver of condition of tyre on wheel to which detection box is adjacent to. A feeler rod 3 operates on a microswitch in the box when it is deflected by the bulge 5 of a deflated tyre. <IMAGE>
Description
Tyre deflation detector.
This invention relates to a device for detecting deflation of a pneumatic tyre of a vehicle, oe it trailer, horse ox, caravan, any vehicle witn pneumatic tyres.
Intro@uction.
Often wnen travelling on motorways, main roads, etc, it has been noted that vehicle drivers pulling so3e form of trailer rave no arparent knowledge of the iack of air in one or more of their trailer tyres, making them potentially dangerous, the deflation detector described below would warn the driver, so action could me taken.
Presently there are not available any devices for advising a ariver tnat a tyre of, for exarple, a caravan being towed cy the car has artially or fully deflate. When this does occur, there is, of coarse, danger not only to tne caravan and towing car, Liut also to other traffic in tne immediate vicinity.
This invention sets out to provide such a device. According to tne present there is provided a device which is activated through contact with the round engaging end section of a p@eumatic tyre as tne @ @ @ @ @ @ tyre is deflating.
Description. Figure 1. shows a device 1 in accordance with the invention mounted on the rear axle 2 oft a caravan. One tyre of the caravan is shown at 4 and a rod 3 extends diagonally downward fron the device 1 to a position adjacent tothe ground engaging end of the tyre 4.
Figure 2. Is also an end view of the device 1 , cut witn tne tyre 4 partially deflated, and the bulge 5 caused by deflation intermittently touching the feeler rod j tnereby sending early warning signals to the driver.
Figure 3. Is also an end view of the device 1, but with the tyre 4 fully deflated, therebycausing nonstop warning to the driver by way of a dasn mounted warning display unit 10
Figure 4. Is a section taken through the device 1 snowing the internal. workings, which consist of a micro switch 9, which when tripped closes an electrical circuit, thereby operating warning display unit 10. Also shown is feeler rod 3, attached witnin device 1 cy secured pivot point 7, feeler rod 3 held in the off position Ly restraining spring 8 . The device 1 is made water tight where feeler rod 3 exits by eans of a soft rubber boot 12. peeler 3 to be nade of plastic, but could be woo, alloy or metal.Could also be made using micro chip anc. rauar type sender unit, with pulse to be @oun@ed ack ofi- tyre wall.
Device 1 to @e attached to axle 2 close to inside of wheel, by means of ju@ilee clips 11, but could be some other form of fast secure fitting.
Figure 5. Is a view of warning display unit 10 ,t@is to oe fitted oy means of sticky pads to dashboard fascia, warning display unit 10 consists of one warning light 13, one warning buzzer 14, and one aster switch 15, to be used when having stop@ed to change wheel.
The device 1 to be electrically connected to warning display unit 10 with two core electric cable 6 with interrediate T junctions 16 to allow for the fitting of one or more extra devices 1.
Figure 6. Is a theoretical diagram of the sack axle of a towinG vehicle and an appliance being towed, ann now the @any devices 1 could oe connected using T junctions 16 in t.le wrin joor 5 The wiring loom 6 would have a quick release plug and socket 17 adjacent to tne towed vehicles taster loom connector. The power will be sourced fro the towing venicles main fuse box 18
Claims (3)
- Claims 1. A device for detecting a puncture and therefore loss of air in the tyre on a wheel on a towed or towing vehicle.2. The device as claimed in 1. consists of a box that is attatched adjacent to the wheel and tyre on the underside of the vehicles axle.3. The device as claimed in claim 1. or claim
- 2. or claim
- 3. when operated by specified deflation of tyre on particular vehicle sends warning via electric cable to console mounted on drivers dashboard.2. has a means for measuring the amount of deflation ie, by physical contact with short rod, or electronic wave, in adjacent tyre.4. The device as claimed in claim 1. or claim
