Brake Sensor Magnet

Some Introduction of Brake sensor

The brake sensor is the type of sensor used in the brake system to help the driver judge the wear of the brake pad, facilitate timely repair and maintenance, and ensure the normal and stable operation of the system.

Principle of brake

The working principle of braking mainly comes from friction. The friction between brake pads and brake discs (drums) and between tires and the ground is used to convert the kinetic energy of the vehicle into heat energy after friction and stop the vehicle. The brake pedal must have sufficient heat dissipation and effective heat transmission from the master brake pump to each brake pump, so as to ensure that the brake pedal can fully transmit the braking force and the braking force caused by failure.

The braking system on the car is divided into disc brake and drum brake. However, in addition to the cost advantage, the efficiency of drum brake is far less than that of disc brake. Therefore, the braking system discussed will only focus on disc brake.

Structure and function of brake sensor

Sensor refers to the device or device that can feel the specified physical quantity and convert it into usable input signal according to a certain law. Simply put, a sensor is a device that converts non electricity into electricity. The sensor usually consists of the following three parts:

(1) The sensitive element refers to the part that can directly feel (or respond to) the measurement, that is, the sensitive element measured through the sensor is converted into a non electric quantity or other quantity that has a definite relationship with the measurement.

(2) The conversion element converts the above non electric quantity into electrical parameters.

(3) The function of the measuring circuit is to convert the electrical parameters input by the conversion element into measurable quantities such as voltage, current or frequency for display, recording, control and processing.

Working Principle of brake sensor

There are basically two kinds of brake pad alarm. The first is a relatively simple mechanical alarm, that is, when the brake pad is worn to expose the alarm, it will make a harsh sound through the friction of the alarm. The second is the sensor type. Under normal working conditions, it is generally normally open, that is, the sensor is always a path. At this time, there will be no alarm display on the instrument panel. When the wire of the sensor is worn off, it becomes an open circuit, and there is an alarm display on the instrument panel to remind the owner of the braking system, so as to get real-time maintenance.The magnet is usually built into the brake sensor.
