Filed: 1983-02-02
Abstract: PURPOSE:To measure easily and surely the tread of a vehicle by connecting a high resistance between the high potential terminal of a resistor forming a length measuring converter together with a flexible conductor and the flexible conductor and measuring the voltage between both. CONSTITUTION:A length measuring conversion sensor 3 is formed of a resistor 5 connecting to a constant current source 8, conductive rubber 6, a flexible conductor 7, etc. As the resistor 5 is short-circuited by the rubber 6 through a pressurizing part, the contact position of a tire 9 with the conductor 7 or the like is measured. When the voltage Vc between the conductor 7 and the ground is measured by connecting a high resistance R between the conductor 7 and the high potential side A of the resistor 5, the voltage V2 corresponding to the position of the tire 9 is determined in accordance with the simple waveform voltage where many max. and min. do not exist and similarly the voltage DELTAV corresponding to the width of the tire 9 is determined by the voltage VR between the resistor 7 and the ground. The tread of the vehicle is thus easily and surely calculated and measured.
