Description

Technical Field

[0001] This utility model relates to the field of brake pad technology, specifically to anti-detachment automotive brake pads. Background Technology

[0002] Automotive brake pads, also known as brake linings, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction pads bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Automotive brake pads are generally composed of a metal backing plate, an adhesive heat insulation layer, and friction linings.

[0003] The friction lining of existing automotive brake pads is usually fixed to one side of a metal backing plate by adhesive bonding. If the metal backing plate bonding process of the brake pad is substandard or the composite material is uneven, the brake pad is prone to delamination and detachment after long-term use. This makes it difficult to fix the friction lining when the adhesive layer is not firmly bonded, and it is also difficult to distribute the force on the adhesive layer during braking. Utility Model Content

[0004] The purpose of this invention is to provide anti-detachment automotive brake pads to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Anti-detachment car brake pads include:

[0007] A metal back plate, wherein a friction pad is movably provided on one side of the metal back plate, and multiple positioning rods are fixedly installed at equal intervals on one side surface of the metal back plate, and multiple positioning holes are opened at equal intervals on one side surface of the friction pad, and mounting holes are symmetrically opened on the other side surface of the friction pad.

[0008] The fastening component is movable inside the mounting hole.

[0009] Furthermore, a sound-absorbing plate is fixedly installed on the other side surface of the metal back plate, and clamping plates are integrally formed symmetrically on both ends of the metal back plate.

[0010] Furthermore, an adhesive layer is provided between the metal backing plate and the friction pad.

[0011] Furthermore, the positioning rod is movably inserted into the positioning hole at the corresponding position.

[0012] Furthermore, threaded rings are symmetrically fixedly installed on one side surface of the metal back plate, and connecting holes are symmetrically opened on one side surface of the friction lining. The connecting holes are fixedly connected to the mounting holes at corresponding positions, and the connecting holes are movably inserted into the threaded rings at corresponding positions.

[0013] Preferably, the fastening assembly includes:

[0014] The fastening bolt is movably located inside the mounting hole and engages with the threaded ring at the corresponding position.

[0015] Washer No. 1 is movably fitted onto the outside of the fastening bolt;

[0016] The No. 2 gasket is movably sleeved on the outside of the fastening bolt, located on the side of the No. 1 gasket.

[0017] Preferably, a rubber ring is fixedly connected to the outside of the fastening bolt between the first washer and the second washer.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By inserting positioning rods into the positioning holes at corresponding positions when bonding friction pads, the installation position accuracy of friction pads is increased. By setting multiple positioning rods on one side surface of the metal backing plate, the position of the friction pads is restricted, and the force transferred from the friction pads to the adhesive layer is distributed, thereby improving the firmness of the adhesive layer after bonding and preventing the friction pads from falling off.

[0020] 2. When the positioning rod is in the corresponding positioning hole, the threaded ring is inserted into the corresponding connecting hole to share the force transferred from the friction lining to the adhesive layer during braking, and is also used to connect and install fastening components.

[0021] 3. When tightening the bolts, first place the washer structure formed by the No. 1 washer, the rubber ring, and the No. 2 washer on the outside of the bolts. After the bolts are tightened, the elasticity of the rubber ring reduces the pressure of the bolts on the friction lining, preventing excessive pressure from the bolts that could damage the friction lining. The connection between the bolts and the threaded ring further increases the stability of the friction lining after installation. At the same time, when the friction lining wears to a certain thickness, the abnormal noise generated by the friction between the bolts and the brake disc will remind the owner to replace the brake pads.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 In this embodiment of the utility model, the anti-detachment automotive brake pad includes a metal backing plate 1. A noise-absorbing plate 102 is fixedly installed on the other side surface of the metal backing plate 1. The noise-absorbing plate 102 reduces the noise generated when the friction lining 103 rubs against the brake disc. A retaining plate 101 is integrally formed symmetrically on both ends of the metal backing plate 1. A friction lining 103 is movably provided on one side of the metal backing plate 1. An adhesive layer 104 is provided between the metal backing plate 1 and the friction lining 103. The adhesive layer 104 connects and fixes the metal backing plate 1 and the friction lining 103. A plurality of positioning rods 107 are fixedly installed at equal intervals on one side surface of the metal backing plate 1. A plurality of positioning holes 109 are equidistantly opened on one side surface of the friction lining 103. Mounting holes 106 are symmetrically opened on the other side surface of the friction lining 103. A fastening component 2 is movably disposed inside the mounting holes 106.

[0030] Specifically, the clamping plate 101 is used to install the brake pads into the brake drum. It is connected to the positioning hole 109 and the positioning rod 107 through a movable insertion, which distributes the force on the adhesive layer 104. The fastening assembly 2 further improves the firmness of the friction lining 103. Example 1

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, the positioning rod 107 is movably inserted into the positioning hole 109 at the corresponding position.

[0032] In this embodiment, when bonding the friction pad 103, the positioning rod 107 is inserted into the positioning hole 109 at the corresponding position. This increases the accuracy of the installation position of the friction pad 103 and shares the force that the friction pad 103 transfers to the adhesive layer 104. By setting multiple positioning rods 107 on one side surface of the metal back plate 1, the position of the friction pad 103 is restricted, the force on the adhesive layer 104 during braking is shared, the bonding firmness of the adhesive layer 104 is improved, and the friction pad 103 is prevented from falling off.

[0033] like Figure 3 and Figure 4 As shown, in this embodiment, a threaded ring 108 is symmetrically fixedly installed on one side surface of the metal back plate 1, and a connecting hole 105 is symmetrically opened on one side surface of the friction lining 103. The connecting hole 105 is fixedly connected to the mounting hole 106 at the corresponding position. The connecting hole 105 and the mounting hole 106 form a stepped groove for installing the fastening component 2. The connecting hole 105 is movably inserted into the threaded ring 108 at the corresponding position.

[0034] In specific implementation, the connecting hole 105 and the mounting hole 106 form a stepped groove. When the positioning rod 107 is aligned with the positioning hole 109 at the corresponding position, the threaded ring 108 is inserted into the connecting hole 105 at the corresponding position. It works with the positioning rod 107 to share the force that the friction pad 103 transfers to the adhesive layer 104 during braking, and is also used to connect and install the fastening assembly 2.

[0035] like Figure 4 and Figure 5 As shown, in this embodiment, the fastening assembly 2 includes: a fastening bolt 201 movably disposed inside the mounting hole 106 and screwed into a threaded ring 108 at a corresponding position; a first washer 202 movably sleeved on the outside of the fastening bolt 201; and a second washer 203 movably sleeved on the outside of the fastening bolt 201 on one side of the first washer 202. A rubber ring 204 is fixedly connected between the first washer 202 and the second washer 203 on the outside of the fastening bolt 201. The washer structure formed by the first washer 202, the rubber ring 204, and the second washer 203 is used to reduce the force exerted by the fastening bolt 201 on the friction lining 103.

[0036] In practice, the first washer 202 and the second washer 203 clamp the rubber ring 204, forming a washer structure with a certain elasticity. When tightening the fastening bolt 201, the washer structure formed by the first washer 202, the rubber ring 204 and the second washer 203 is first placed on the outside of the fastening bolt 201. After the fastening bolt 201 is tightened, the elasticity of the rubber ring 204 reduces the pressure of the fastening bolt 201 on the friction lining 103, avoiding excessive pressure from the fastening bolt 201 on the friction lining 103, which could cause damage to the friction lining 103. Thus, the connection between the fastening bolt 201 and the threaded ring 108 further increases the firmness of the friction lining 103 after installation. At the same time, after the friction lining 103 wears to a certain thickness, the abnormal noise generated by the friction between the fastening bolt 201 and the brake disc reminds the car owner to replace the brake pads.
