Description

Technical Field

[0001] This invention relates to the field of friction brakes, and more specifically to a friction brake wear detection device and its detection method. Background Technology

[0002] Friction brakes utilize the frictional resistance generated when two moving surfaces come into contact to convert the kinetic and potential energy of a moving vehicle into heat energy, thereby slowing down or stopping the vehicle. Disc brakes offer advantages such as stable braking performance (the braking coefficient is linearly related to the coefficient of friction), good braking performance on various road surfaces, and simple structure for easy maintenance. Therefore, for the safety of the entire vehicle, most commercial vehicles currently use disc brakes.

[0003] With technological advancements, most vehicle models have replaced ADS with EBS, which includes Intelligent Brakeforce Distribution. EBS intelligently distributes braking force based on the thickness of the front and rear brake pads, ensuring consistent wear on both axles and reducing the need for brake pad replacement due to uneven wear caused by rapid pad wear. Therefore, vehicles with EBS must be equipped with brakes featuring wear detection devices to effectively distribute braking force and detect pad thickness. Thus, the aforementioned issues urgently need to be addressed. Summary of the Invention

The two ends of the second U-shaped frame 24 are vertically fixed to the inner bottom surface of the lower housing 2, and a guide rod 26 is vertically provided in the middle of its interior. The lower end of the guide rod 26 extends vertically downwards from the lower surface of the lower housing 2 and is vertically slidably connected to the lower housing 2. A pressure plate 25 is provided between the upper ends of the first push plate 20 and the second push plate 21.

[0031] The present invention provides a detection method for a friction brake wear detection device, such as... Figure 1 As shown, it includes the following steps:

[0032] Step 1: Under the action of external force, the upper housing 1 and the lower housing 2 drive the first push plate 20 and the second push plate 21 to contact or move away from the friction plate 23 to achieve the braking and disengaging braking functions.

[0033] Step 2: When the thickness of the friction plate 23 decreases, the gap between the friction plate 23 and the first push plate 20 and the second push plate 21 increases. At this time, under the drive of the drive motor 7, the first movable block 15 and the second movable block 16 move synchronously through the transmission mechanism, thereby driving the first push plate 20 and the second push plate 21 to move towards the friction plate 23 to make up for the gap caused by the wear of the friction plate 23.

[0034] Step 3: During this process, the guide rod 26 moves with the first push plate 20 and the second push plate 21. At this time, the metal ring 27 and the PCB board 29 are in contact with each other and the displacement changes are generated accordingly. The corresponding linear voltage signal is output and finally converted into the corresponding wear signal, so that the wear thickness of the friction plate 23 can be monitored in real time.

[0035] The beneficial effects of the present invention are as follows: Through the coordinated use of the main gear 9, the driven gear 11 and the transmission chain 12, the first threaded rod 13 and the second threaded rod 14 can move synchronously, thereby driving the first push plate 20 and the second push plate 21 to move and adjust when the thickness of the friction plate 23 decreases, in order to compensate for the gap caused by the wear of the friction plate 23; and through the coordination of the guide rod 26, the metal ring 27, the PCB board 29 and the connector pin 30, real-time monitoring of the wear thickness of the friction plate 23 can be achieved, thereby facilitating intelligent braking force distribution.

3. The detection method of the friction brake wear detection device according to any one of claims 1 to 2, characterized in that... Includes the following steps: Step 1: Under the action of external force, the upper and lower housings drive the first and second push plates to contact or separate from the friction plates to achieve the braking and disengaging braking functions; Step 2: When the thickness of the friction plate decreases, the gap between the friction plate and the first and second push plates increases; at this time, driven by the drive motor, the first and second movable blocks move synchronously through the transmission mechanism, thereby driving the first and second push plates to move towards the friction plate to compensate for the gap caused by the wear of the friction plate. Step 3: During this process, the guide rod moves with the first and second push plates. At this time, the displacement changes due to the change in the contact displacement between the metal ring and the PCB board will generate corresponding displacement changes, outputting corresponding linear voltage signals, which will eventually be converted into corresponding wear signals, so that the wear thickness of the friction plate can be monitored in real time.
