The arm may be connected to the mounting base 50 by welding, the signal transceiver 40 is mounted on the arm, and the mounting base 50 can rotate the arm and the signal transceiver 40, so that the signal transceiver 40 and the hub 20 can rotate synchronously around the crankshaft.
In this embodiment 1, the mounting seat 50 is annular, the first end of the supporting arm, the first notch 12 and the second notch 22 are collinear, and the second end of the supporting arm is connected to the curved surface of the mounting seat 50.
Further, the signal transceiver 40 includes a signal transmitting end and a signal receiving end; the signal transmitting end is used for transmitting a first monitoring signal, when the signal transceiver 40, the first notch 12 and the second notch 22 are collinear, the first monitoring signal passes through the first notch 12 and the second notch 22, when the second notch 22 and the first notch 12 are dislocated, the first monitoring signal is reflected by the first rim 11 to form a second monitoring signal, and the signal receiving end is used for receiving the second monitoring signal.

Example 3:
this example 3 provides a method of pulley failure monitoring using the pulley failure monitoring system of example 2, comprising:
step S101: acquiring a feedback signal by using a signal transceiver 40 of the monitoring device, and transmitting a second monitoring signal to the electronic control unit when the acquired feedback signal is a second monitoring signal, wherein the second monitoring signal is used for indicating that the outer rim 10 of the belt pulley device is dislocated with the hub 20;

Further, the protection control of the pulley device according to the second monitoring signal further includes: and triggering an alarm prompt according to the displacement signal.
Further, the acquiring the feedback signal by the signal transceiver 40 of the monitoring device includes:
when the signal transceiver 40, the first notch 12 of the first rim 11 and the second notch 22 of the second rim 21 are collinear, the first monitoring signal transmitted by the signal transmitting end of the signal transceiver 40 passes through the first notch 12 and the second notch 22, and the feedback signal received by the signal receiving end of the signal transceiver 40 is null;
when the second gap 22 is misaligned with the first gap 12, the first monitoring signal transmitted by the signal transmitting end is reflected by the first rim 11 where the first gap 12 is located to form a second monitoring signal, and the feedback signal received by the signal receiving end is the second monitoring signal.
In this embodiment 3, when the rubber ring 30 does not fail, the signal transceiver 40, the second notch 22 and the first notch 12 are collinear, the signal transceiver 40 transmits the first monitoring signal, the first monitoring signal passes through the second notch 22 and the first notch 12, the signal transceiver 40 cannot receive the second monitoring signal, at this time, the feedback signal received by the signal receiving end of the signal transceiver 40 is null, which indicates that the signal transceiver 40 does not receive the second monitoring signal, and the rubber ring 30 does not fail.
When the rubber ring 30 fails, the second notch 22 is dislocated from the first notch 12, the signal transceiver 40 transmits a first monitoring signal, the first monitoring signal passes through the second notch 22 and is reflected by the first rim 11 to form a second monitoring signal, and a feedback signal received by the signal transceiver 40 is the second monitoring signal, which indicates that the rubber ring 30 fails. The electronic control unit can judge that the rubber ring 30 is invalid according to the second monitoring signal, and further the electronic control unit carries out protection control on the belt pulley device, avoids the problem that functional parts such as water pumps, generators and the like are invalid because the belt pulley rotates under the state that the rubber ring 30 is invalid, and avoids the damage of an engine.
According to the belt pulley device, the belt pulley failure monitoring system and the monitoring method, whether the rubber ring 30 fails or not is monitored at any time through structural design and the addition of the monitoring device (comprising the position sensor), when the rubber ring fails, the monitoring device synchronously transmits a displacement signal to the electronic control unit, the oil injector 91 is controlled to cut off oil, and an automobile owner is informed on the instrument panel 92, so that larger faults of an engine are avoided, and larger loss is avoided. The innovation points of the invention are as follows: a first notch 12 is added on a first rim 11 of the outer rim 10, a second notch 22 is added on a second rim 21 of the hub 20, the hub 20 is rigidly connected with a position sensor with a wireless transmission function, and the first notch 12, the second notch 22 and the position sensor are collinear or aligned. Under normal conditions, the first monitoring signal sent by the position sensor can pass through the first notch 12 and the second notch 22, and no reflection signal is generated; when the rubber ring 30 fails, the first notch 12 and the second notch 22 rotate relatively, the first rim 11 beside the first notch 12 of the outer rim 10 blocks a channel of a first monitoring signal, the first monitoring signal is reflected, a second monitoring signal formed after reflection can be received by the position sensor, at the moment, the position sensor sends the second monitoring signal to the electronic control unit through wireless transmission, the electronic control unit judges that the rubber ring 30 fails, and controls the oil injector 91 to cut off oil and inform an owner of the oil injector on the instrument panel 92.

During engine operation, the sensor is rigidly connected to the hub 20 and both are able to rotate synchronously. Normally, the position sensor cannot receive the reflected signal, so the position sensor does not send a signal to the electronic control unit. When the rubber ring 30 is invalid, the outer wheel ring 10 and the hub 20 rotate relatively, the first notch 12 shifts in position, the position sensor can receive a reflected signal, then the position sensor sends a second monitoring signal to the displacement monitoring module 70 through wireless transmission, the displacement monitoring module 70 performs analog-to-digital conversion on the second monitoring signal to obtain a displacement signal, and the displacement monitoring module 70 sends the displacement signal to the control module 80. The control module 80 controls the fuel injector 91 to cut off fuel according to the displacement signal and displays warning information on an instrument panel 92 to warn a driver that the vehicle has a fault. Compared with a normal oil injection strategy, the oil injector 91 is influenced by the belt pulley rubber ring 30, so that the oil injection control mode is safer and more reliable, and the oil injector 91 is prevented from continuously injecting oil when the rubber ring 30 is aged.
The invention has low cost, only needs to change the design on the basis of the prior belt pulley and adds the notch, the position sensor and the mounting seat 50, has little cost change, can realize the function of monitoring the state of the rubber ring 30, and prevents the rubber ring 30 from continuously damaging an engine after losing efficacy.
The present invention is not limited to the above embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
