[0017] Example
[0018] like Figure 1 As shown: A commercial vehicle disc brake wear alarm monitoring system, including a disc brake 1, a wear alarm sensor 2, a controller 3, and a cab instrument 4;
[0019] The disc brake 1 is provided with a wear alarm sensor 2 , which is electrically connected to a controller 3 , and the controller 3 is connected to a cab instrument 4 via a CAN bus.
[0020] Preferably, the wear alarm sensor 2 is an angle sensor or a displacement sensor, and the wear alarm sensor 2 is mounted on the brake caliper 1.1 on the disc brake 1. When the brake caliper 1.1 on the disc brake 1 undergoes axial displacement, the wear alarm sensor 2 will undergo an angle or displacement change, causing an output voltage change of the internal circuit of the wear alarm sensor 2; the angle or displacement change of the wear alarm sensor 2 is calibrated and fitted to its output voltage in a directly proportional relationship, and the wear condition of the brake lining 1.2 and the brake disc 1.3 can be indirectly determined through the voltage, thereby achieving accurate alarm.
[0021] It also includes an alarm light; the alarm light is electrically connected to the cab instrument 4; the voltage value emitted by the wear alarm sensor 2 decays to the pre-alarm value, and the remaining wear of the brake lining 1.2 displayed on the cab instrument 4 reaches the limit value; the voltage value emitted by the wear alarm sensor 2 decays to the limit value, and the brake lining displayed on the cab instrument 4 is consumed, and the alarm light is used for prompting.
[0022] It also includes a buzzer; the buzzer is electrically connected to the cab instrument 4; it is also used to indicate the wear degree of the disc brake 1.
[0023] The controller 3 is an EBS controller; it may also be other controllers with the same function of converting electrical signals into CAN signals.
[0024] The wear alarm sensor 2 is electrically connected to the controller 3 through the wear alarm harness 5; plug connectors are provided at both ends of the wear alarm harness 5; the wear alarm sensor 2 is assembled on each disc brake 1 of the vehicle, adopts a parallel structure, and is completely independent of each other. When a harness failure occurs in a single sensor, it will not affect the normal operation of other sensors; the circuit is simple and easy to maintain.
