Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
The automobile brake pad is also called as automobile brake shoe, and refers to a friction material fixed on a brake drum or a brake disc rotating with a wheel, wherein a friction lining and a friction pad bear external pressure to generate friction action so as to achieve the aim of reducing the speed of the automobile.
At present, disc brakes are adopted in the main stream of passenger vehicles, brake pads are consumed parts, and need to be replaced regularly after being lower than a safe thickness threshold value, otherwise, braking and driving safety are affected.
At present, the main automobile products in the market do not monitor the thickness of the brake pad, and only actively observe the thickness during maintenance and maintenance or passively replace the brake pad after the insufficient thickness of the brake pad is discovered when the brake is weakened. And for some brake block thickness monitoring schemes, such as inner caliper resistance and wires, or laser and ultrasonic radar monitoring schemes based on brake blocks, the monitoring schemes are greatly influenced by the environment, have lower feasibility and universality and are difficult to popularize.
As shown in fig. 1-4, a specific embodiment of a disc brake pad thickness monitoring device with an ultrasonic radar is shown, which includes a U-shaped brake caliper 2 fixed on a frame, a brake disc 5 connected to a wheel is disposed between the brake caliper 2, a first brake pad 3 and a second brake pad 3.1 are disposed on two sides of the brake disc, the first brake pad 3 is connected to an inner side surface of the brake caliper 2, at least two receiving integrated ultrasonic radars 1 are connected to the other side surface of the brake caliper 2 to monitor the distance change between the ultrasonic radar 1 and the second brake pad 3.1 in real time, the ultrasonic radar 1 is connected to a vehicle controller, the second brake pad 3.1 is connected to a brake piston 4 driven by a power mechanism, the present scheme adopts a redundant design of double ultrasonic radar probes to improve the measurement reliability, install two ultrasonic radar 1 on brake caliper 2 to through real time monitoring radar probe and No. two brake block 3.1 back distances, contrast two radar measured data, know the comprehensive wearing and tearing volume of brake block in real time, thereby reach the purpose of real time monitoring brake block thickness wearing and tearing volume, measure accuracy, reliability, feasibility, commonality height, easily popularize and promote.
As shown in fig. 2 and 3, the sum of the wear thicknesses of the left brake pad and the right brake pad can be calculated by the distances a1 and a2 from the ultrasonic radar to the back surface of the brake disc before and after wear, namely the comprehensive wear amount of the brake pad is d:
d＝a2–a1；
two ultrasonic radar are arranged through the installation, adopt the phase detection method, can accurate measurement a1, a2, and be difficult for receiving external environment influence, adopt the purpose of two radars to carry out redundant measurement, avoid because the dirty measurement interference that brings in the brake block back.
As shown in fig. 4, a driving circuit, a modulator, and a phase comparison processor are disposed between the vehicle controller and the ultrasonic radar, the driving circuit, the modulator, the phase comparison processor, and the signal generator form a transmitting path, a preamplifier, a demodulation filter, and a phase comparison processor (the same as the transmitting path) are disposed between the vehicle controller and the ultrasonic radar, and the preamplifier, the demodulation filter, and the phase comparison processor (the same as the transmitting path) form a receiving path.
Specifically, the method can be as follows: the signal generator drives the ultrasonic radar to emit ultrasonic waves through the modulator and the driving amplification circuit, the ultrasonic waves are returned through the back of the brake pad, the signals are demodulated and filtered through the pre-amplification circuit, and then the signals are connected with the automobile controller through phase comparison processing, and the distance is calculated.
As an improved embodiment mode, the power mechanism is an oil pump, no limitation is made on the model specification, and the power mechanism can be selected according to actual requirements.
