Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more specifically, to a vehicle brake disc wear detection and warning device. Background Art

[0002] The brake disc is an important component in the disc brake system. It is an annular part that rotates with the wheel during vehicle driving. When the driver steps on the brake pedal, the brake caliper clamps the brake disc, and braking force is generated through friction to stop the wheel from rotating, thereby achieving vehicle parking. During the use of the brake disc, with the increase in the number of brakings, the brake disc will gradually wear. At this time, a brake disc wear detection and warning device is needed to detect and give a warning about the brake disc.

[0003] As disclosed in a Chinese patent: A drum brake pad wear monitoring and warning device, application number: CN202022167948.X, which uses wireless signal transmission and secondary warning, that is, two sensing lines are set. The first is a warning, indicating the wear degree of the brake pad; the second is an alarm, when the wear of the brake pad reaches a certain limit value, it must be replaced. The first warning provides the driver with the wear degree of the brake pad, enabling early prediction and giving a time concept for preparation of replacement, changing the mandatory maintenance operation, and maximizing the use value of the brake pad. The second alarm means that when the wear of the brake pad reaches the limit value, it must be replaced to avoid the rivets being exposed when the brake pad is too thin, damaging the brake drum and causing vehicle braking failure, ensuring no hidden danger in vehicle braking safety.

[0004] However, in the above technical solution, when braking the vehicle, the brake caliper clamps the brake disc, and braking force is generated through friction to stop the wheel from rotating. Therefore, the brake disc will inevitably wear during braking, so it is impossible to timely detect the brake disc. In today's market, most are for wear monitoring and warning of brake pads, and then the brake disc is detected during subsequent maintenance and replacement of the brake pads. It is impossible to well detect and warn the wear of the brake disc, resulting in the possibility of not timely discovering that the brake disc wears to the critical point, reducing the driving safety and reliability. Summary of the Utility Model

[0005] The main purpose of the present utility model is to provide a wear detection and warning device for vehicle braking brake discs, which can effectively solve the problem in the background technology that when braking a vehicle, the brake caliper clamps the brake disc to generate braking force through friction to stop the wheel from rotating. Therefore, the brake disc is inevitably worn during braking, and it is impossible to timely detect the brake disc. In today's market, most of them monitor and warn the wear of brake pads, and then detect the brake disc only when overhauling and replacing the brake pads later. It is impossible to well detect and warn the wear of the brake disc, resulting in the possibility that the wear of the brake disc cannot be timely detected until the critical point, reducing the driving safety and reliability.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0007] A wear detection and warning device for vehicle braking brake discs, including a brake disc and a brake caliper. An installation hole is provided on the brake disc. A connecting plate is provided on one side of the brake disc. Guide chutes are provided on both sides of the connecting plate. A sliding column is slidably arranged in the guide chutes. A pressing plate is provided on the side of the sliding column close to the brake disc. A spring is provided on the side of the pressing plate away from the brake disc. The spring is in a deformed state. A limiting plate is fixedly provided on the side of the sliding column away from the pressing plate. A touch sensor is provided between the limiting plate and the connecting plate.

[0008] Preferably, one end of the spring is fixedly connected to the connecting plate, and the touch sensor is fixedly installed on the sliding column.

[0009] Preferably, the pressing plate includes a pressing plate base. A plurality of ball grooves are provided on the pressing plate base. Ball bearings are provided in the ball grooves.

[0010] Preferably, a closed abutting plate is provided on one side of the pressing plate base. A connecting bolt is threadedly arranged on the closed abutting plate.

[0011] Preferably, the pressing plate base and the closed abutting plate are fixedly connected by a connecting bolt, and the closed abutting plate is fixedly connected to the sliding column.

[0012] Preferably, the spring is fixedly connected to the closed abutting plate.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] (1) When the present utility model is in use, when the brake disc wears due to the braking of the brake caliper, the thickness of the brake disc will change. At this time, a gap will appear between the ball and the brake disc. Subsequently, the deformed spring rebounds, causing the pressure plate to move towards the brake disc. The pressure plate drives the sliding column to move, and the sliding column drives the limiting plate and the touch sensor to move, causing the touch sensor to move towards the connecting plate. When the brake disc wears to the warning thickness, the touch sensor will come into contact with the connecting plate, and then the touch sensor is activated to send a signal to the vehicle's central control, and the alarm on the vehicle is activated through the vehicle's central control to give a warning to the user. It can effectively detect and warn the wear condition of the brake disc in real time, facilitating the staff to replace the brake disc in a timely manner. Description of the Drawings

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] As Figures 1 to 3As shown in the figure, a wear detection and warning device for a vehicle braking brake disc includes a brake disc 1 and a brake caliper 2. An installation hole 3 is provided on the brake disc 1. A connecting plate 4 is provided on one side of the brake disc 1. Guide sliding grooves 5 are provided on both sides of the connecting plate 4. A sliding column 6 is slidably arranged in the guide sliding grooves 5. A pressing plate 7 is provided on the side of the sliding column 6 close to the brake disc 1. A spring 8 is provided on the side of the pressing plate 7 away from the brake disc 1. The spring 8 is in a deformed state. A limiting plate 9 is fixedly arranged on the side of the sliding column 6 away from the pressing plate 7. A touch sensor 10 is arranged between the limiting plate 9 and the connecting plate 4.

[0023] As Figure 4 and Figure 5 shown, in another embodiment of the present utility model, the pressing plate 7 includes a pressing plate base 701. A plurality of ball grooves 702 are provided on the pressing plate base 701. A ball 703 is arranged in each ball groove 702;

[0024] A closed abutting plate 704 is provided on one side of the pressing plate base 701. A connecting bolt 705 is threadedly arranged on the closed abutting plate 704. When the brake disc 1 rotates, the friction between the pressing plate 7 and the brake disc 1 is reduced by a plurality of balls 703 in contact with the brake disc 1. When the balls 703 are worn, the connecting bolt 705 is rotated to release the fixation between the pressing plate base 701 and the closed abutting plate 704, and then the pressing plate base 701 and the closed abutting plate 704 are separated. At this time, the closed abutting plate 704 will no longer close the ball grooves 702, and then the worn balls 703 in the ball grooves 702 can be replaced, reducing the maintenance cost.

[0025] The working principle of the wear detection and warning device for a vehicle braking brake disc:

[0026] During use, first install the brake disc 1 to the designated position through the mounting holes 3, and fixedly install the connecting plate 4 and the brake caliper 2 to the vehicle. Then, electrically connect the touch sensor 10 to the vehicle's central control. At this time, when the balls 703 are in contact with the brake disc 1, the frictional force between the pressing plate 7 and the brake disc 1 is reduced by the plurality of balls 703 in contact with the brake disc 1. When the brake disc 1 wears due to the braking of the brake caliper 2, the thickness of the brake disc 1 will change. At this time, a gap will appear between the balls 703 and the brake disc 1. Subsequently, the deformed spring 8 rebounds, causing the pressing plate 7 to move towards the brake disc 1. The pressing plate 7 drives the sliding column 6 to move, and the sliding column 6 drives the limiting plate 9 and the touch sensor 10 to move, causing the touch sensor 10 to move towards the connecting plate 4. When the brake disc 1 wears to the warning thickness, the touch sensor 10 will come into contact with the connecting plate 4, and then the touch sensor 10 is activated to send a signal to the vehicle's central control, and the alarm on the vehicle is activated by the vehicle's central control to give a warning to the user. It can effectively detect and warn the wear condition of the brake disc 1 in real time, facilitating the staff to replace the brake disc 1 in a timely manner.

[0027] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present invention, rather than limitations on the embodiments of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to list all the embodiments here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
