Claims

[Claims for Utility Model Registration] 1. In a wear detection device having a detector whose circuit is opened at the limit of lining wear, a starting switch is connected to an alarm display circuit such as a lamp, 1, and a base of a transistor provided in the circuit is provided. The output of the first transistor switching circuit is connected to the terminal as a circuit for inspecting the detector and the detector lead wire, and the output of the second transistor switching circuit, which continuously operates when the detector is open circuited due to wear of the lining, is connected through a diode. In the former circuit, one end of a series circuit of two resistors with a detector connected in the middle is connected to the ■ terminal of the power supply via a start switch, and one end B of the detector S is connected with a resistor, A series circuit of capacitors is connected in parallel to another resistor of the series circuit of resistors, the terminal is connected to the e terminal of the power supply, and the midpoint of the series circuit of the resistor and capacitor is connected to the control terminal of the first transistor. However, in the latter circuit, a series circuit of a resistor and a diode is connected in parallel between one end of the starting switch and the other end B of the detector S of the series circuit of the resistor with the detector S connected in the middle, The middle point of the series circuit of a resistor and a diode is connected to the control terminal of the second transistor via the diode, and the output of the second transistor switching circuit is input to the third transistor via the resistor. The output of the transistor is connected to the second transistor through the diode.
A wear alarm device which is formed by additionally connecting a memory circuit to the input of the transistor. 2. Utility model registration claim 1, in which a delay function is added to the former memory circuit so that the alarm display circuit such as a lamp does not continue to operate in the event of chattering of the detector due to vehicle vibration, etc. Wear warning device.
