Description

BACKGROUND area

[0001] Exemplary embodiments of the present disclosure relate to a brake pad guide for a brake device and in particular a brake pad guide which can prevent the generation not only of rattling noises but also of drag torques. Discussion of the background

[0002] Generally speaking, a brake pad in a braking system is a component that comes into contact with a brake disc to provide braking force. A brake pad consists of several parts.

[0003] However, when a brake pad is brought into contact with or separated from the brake disc when a brake pedal is applied or released, the parts can interfere with each other, producing rattling noises. Furthermore, when the brake pedal is released, the brake pad and brake disc may not be completely separated but remain in contact, generating drag torque. Therefore, there is a need for a device suitable for solving this problem.

[0004] The prior art of the present disclosure is disclosed in the published Korean patent application No. 10-2019-0021566, published on March 6, 2019, entitled “Pad Liner for Caliper”. IT MI0020122155 A, JP H09 - 89018 A and KR 10 2010 059 145 A each disclose a brake pad guide for a brake device comprising a brake pad guide body arranged between several pin elements, and brake pad guide support parts extending from two opposite ends of the brake pad guide body and each configured to support the several pin elements. OVERVIEW

[0005] Various embodiments relate to a brake pad guide for a braking device, which can prevent the generation not only of rattling noises but also of drag torques.

[0006] According to one embodiment, a brake pad guide for a brake device can comprise: a brake pad guide body arranged between several pin elements; brake pad guide support parts extending from two opposite ends of the brake pad guide body, each configured to support the several pin elements; a brake pad guide return part connected to the brake pad guide body to press against a first brake pad and brought into contact with the first brake pad to provide an elastic restoring force when a brake pedal is released, such that the first brake pad is returned to its initial state; and a brake pad guide extension part connected to the brake pad body and brought into contact with a second brake pad to press against the second brake pad.

[0007] The brake pad guide reset element comprises: a first brake pad guide reset element extending from the brake pad guide body to one side of the brake pad guide and brought into contact with a first backing plate of the first brake pad in order to press against the first backing plate; and a second brake pad guide reset element extending from the first brake pad guide reset element and bent in the direction of a first friction element of the first brake pad, and brought into contact with the first backing plate.

[0008] The brake pad guide reset part may further comprise a first reset indicator part which extends from one end of the second brake pad guide reset part and is bent in a direction towards the brake pad guide extension part.

[0009] The second brake pad guide reset part may comprise: a second brake pad guide reset projection part extending from the first brake pad guide reset part towards the first carrier plate; and a second brake pad guide contact part extending from the second brake pad guide reset projection part towards a first friction element, bent at a predetermined angle, brought into contact with the first carrier plate, and having an end connected to the first reset indicator part.

[0010] The brake pad guide extension part may comprise: a brake pad guide extension body extending from the brake pad guide body towards one side opposite one side of the brake pad guide and brought into contact with a second backing plate of the second brake pad in order to press against the second backing plate; and a brake pad guide contact part, brought into contact with the second backing plate, extending from the brake pad guide extension body towards a second friction element of the second brake pad, and bent at a pre-set angle.

[0011] The angle between the brake pad guide contact part and the brake pad guide extension body can exceed 90 degrees. When it comes into contact with the second backing plate, the brake pad guide contact part can be elastically deformed and brought into surface contact with the second backing plate.

[0012] The brake pad guide extension part may further include a second reset indicator part which extends from one end of the brake pad guide contact part towards the brake pad guide reset part and is bent at a predetermined angle.

[0013] Each of the brake pad guide support parts may further comprise: a brake pad guide support body extending from one of the two opposite ends of the brake pad guide body and bent in the direction of the respective pin element, and configured to support the respective pin element; and a brake pad guide fastening part extending from the brake pad guide support body, bent in the direction of the respective pin element, and brought into contact with the respective pin element.

[0014] According to the embodiments described in the present disclosure, the brake pad guide for a brake device can apply a load by pressing against the first and second brake pads at regular positions when the brake is applied or released, thereby preventing rattling noises.

[0015] Furthermore, the brake pad guide can separate the first and second brake pads from the brake disc by applying an elastic restoring force to the first brake pad via the brake pad guide return element when the brake pedal is released, thus preventing the generation of drag moments.

[0016] Furthermore, since the brake pad guide extension part and the second support plate of the second brake pad meet at a right angle when the brake pad guide extension part is brought into contact with the second support plate, the brake pad guide extension part and the brake pad guide extension part can be brought into surface contact with each other, such that the brake pad guide extension part stably supports the second brake pad.

[0017] Since the brake pad guide reset piece incorporates the first reset indicator, this indicator can also be brought into contact with the brake disc to produce a noise when the first friction element is worn. This allows a driver to quickly determine when the brake pads need replacing.

[0018] Since the brake pad guide extension incorporates the second reset indicator, this second indicator can also be brought into contact with the brake disc to produce a noise when the second friction element is worn. This allows a driver to quickly determine when the brake pads need replacing.

[0022] Referring to the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. 8 comprises a brake device 1 for a vehicle according to an embodiment of the present disclosure comprising several pin elements 10, a first brake pad 20, a second brake pad 30, a brake disc 40, a pressure part 50 and a brake pad guide 2 for a brake device.

[0023] The brake pad guide 2 for a brake device according to the embodiment of the present disclosure comprises a brake pad guide body 100, two brake pad guide support parts 200, a brake pad guide return part 300, and a brake pad guide extension part 400. The brake pad guide body 100 is arranged between the two pin elements 10. The two pin elements 10 are arranged in a brake caliper body 60 such that they are spaced apart from each other. The brake caliper body 60 has a (not shown) perforated mounting part formed in a central region thereof and (based on Fig. 1) is arranged in a top-to-bottom direction, and the two pin elements 10 are installed in the mounting part in such a way that they are spaced apart from each other.

[0024] The brake pad guide body 100 is arranged between the two pin elements 10. The brake pad guide body 100 has a first brake pad guide body 110, a second brake pad guide body 120, and a third brake pad guide body 130. The first brake pad guide body 110 is arranged between the two pin elements 10. The second brake pad guide body 120 is curved and extends laterally from the first brake pad guide body 110. The second brake pad guide body 120 is curved and extends downwards from the first brake pad guide body 110 (based on the Fig. 3 and Fig. 4) The third brake pad guide body 130 is bent and extends from the first brake pad guide body 110 to the other side. Here, the third brake pad guide body 130 is bent and extends downwards from the first brake pad guide body 110 (based on the Fig. 3 and Fig. 4).

[0025] The two brake pad guide parts 200 each extend from one of the two ends of the brake pad guide body 100 and serve to support one of the two pin elements 10 each. More precisely, the two brake pad support parts 200 of the brake pad guide body 100 extend such that they are each located under one of the two support elements 10 (based on the Fig. 3 and Fig. 4) and support the respective pin element 10. The brake pad guide 2 for a brake device can be prevented from moving downwards on the two pin elements 10, thus effectively preventing rattling noises.

[0026] The brake pad guide reset element 300 is connected to the brake pad guide body 100 in such a way that it presses against the first brake pad 20 and is brought into contact with the first brake pad 20 in such a way that it provides an elastic restoring force when a brake pedal is released, thereby returning the first brake pad 20 to its initial state.

[0027] The brake pad guide reset part 300 can apply a load via contact with the first brake pad 20 and press against the first brake pad 20 in such a way that the first brake pad 20 is prevented from moving upwards, thus effectively preventing rattling noises.

[0028] The brake pad guide return element 300 extends from the second brake pad guide body 120 of the brake pad guide body 100 towards the first brake pad 20 and is in contact with a first support plate 21 of the first brake pad 20. The brake pad guide return element 300 is elastically deformed by the first brake pad 20, which is moved towards the brake disc 40 by the pressure element 50 when the brake pedal is actuated, and applies an elastic restoring force to the brake pad 20 when the brake pedal is released. The pressure element 50 is mounted in the brake caliper body 60 and comprises a motor module (not shown), a threaded rod (not shown), a nut (not shown), and a piston (not shown). The pressure part 50 can be modified in various ways, as long as the pressure part 50 presses against the first brake pad 20.

[0029] The brake pad guide extension part 400 is connected to the brake pad guide body 100 and presses the second brake pad 30 through contact with it. The brake pad guide extension part 400 extends from the third brake pad guide body 130 of the brake pad guide body 100 towards the second brake pad 30 and is in contact with a second support plate 31 of the second brake pad 30. The brake pad guide extension part 400 can apply a load through contact with the second brake pad 30 and press against it in such a way that the second brake pad 30 is prevented from moving upwards, thus effectively preventing rattling noises.

[0030] The brake pad guide reset element 300 comprises a first brake pad guide reset element 310, a second brake pad guide reset element 320, and a first reset indicator element 330. The first brake pad guide reset element 310 extends from the brake pad guide body 100 to one side and presses against the first support plate 21 of the first brake pad 20 by means of contact with the first support plate 21. More precisely, the first brake pad 20 comprises the first support plate 21 and a first friction element 22. The first brake pad 20 is arranged on one side of the brake disc 40 such that it moves on the two pin elements 10. More precisely, the first support plate 21 has two first through-holes 21a through which the two pin elements 10 are guided. This structure allows the first brake pad 20 not only to be easily coupled to the two pin elements 10, but also to be moved along the two pin elements 10.

[0031] The first friction element 22 is connected to the first carrier plate 21 and is brought into contact with the brake disc 40. The first friction element 22 is made of an elastic material and is brought into contact with one side of the brake disc 40. The first friction element 22 is connected to the first carrier plate 21 such that it faces one side of the brake disc 40.

[0032] The first brake pad guide reset element 310 extends horizontally from the brake pad guide body 100 and is inserted into a first mounting groove 21b of the first carrier plate 21 such that it is in contact with the first carrier plate 21. The first brake pad guide reset element 310 is elastically deformed and deformed at a predetermined angle when it is brought into contact with the first carrier plate 21.

[0033] The second brake pad guide reset element 320 is curved and extends from the first brake pad guide reset element 310 towards the first friction element 22 of the first brake pad 20 and is in contact with the first carrier plate 21. The second brake pad guide reset element 320 is in contact with the central area of ​​the first carrier plate 21. The first friction element 22 has a first coupling groove 22a formed in its center, and the second brake pad guide reset element 320 is inserted into the first coupling groove 22a and is in contact with the first carrier plate 21.

[0034] The second brake pad guide reset element 320 is elastically deformed by the first brake pad 20, which is moved towards the brake disc 40 by the pressure element 50 when the brake pedal is pressed, and provides a restoring force to the first brake pad 20 when the brake pedal is released.

[0035] The first reset indicator part 330 is curved and extends from one end of the second brake pad guide reset part 320 such that it faces the brake pad guide extension part 400. When the first friction element 22 is worn, the first reset indicator part 330 comes into contact with the brake disc 40 and produces a noise to inform the driver that it is time to replace the first brake pad 20. Thus, the driver can recognize when it is time to replace the first brake pad 20.

[0036] The second brake pad guide reset element 320 has a second brake pad guide reset projection element 321 and a second brake pad guide reset contact element 322. The second brake pad guide reset projection element 321 projects from the first brake pad guide reset element 310 towards the first carrier plate 21. The second brake pad guide reset projection element 321 projects in a horizontal direction.

[0037] The second brake pad guide reset contact part 322 extends from the second brake pad guide reset projection part 321 towards the first friction element 22 such that it is bent at a predetermined angle and is in contact with the first reset indicator part 330. The second brake pad guide reset contact part 322 extends downwards from the second brake pad guide reset projection part 321 (based on Fig. 3) that it is bent at a predetermined angle and is in contact with the first support plate 21. When the brake pedal is released, the second brake pad guide return contact part 322 provides an elastic restoring force to the first brake pad 20.

[0038] The brake pad guide extension part 400 comprises a brake pad guide extension body 410, a brake pad guide contact part 420, and a second reset indicator part 430. The brake pad guide extension body 410 extends from the brake pad guide body 100 to the other side and presses against the second support plate 31 of the second brake pad 30 through contact with it. More precisely, the second brake pad 30 comprises the second support plate 31 and a second friction element 32. The second support plate 31 is located on the other side of the brake disc 40 and is connected to the two pin elements 10. The second support plate 31 has two through holes 31a through which the two pin elements 10 are guided (see Figure 1). Fig. 5, Fig. 6 to Fig. 7) This structure allows the second brake pad 30 to be easily coupled to the two pin elements 10.

[0039] The second friction element 32 is connected to the second backing plate 31 and is brought into contact with the brake disc 40. The second friction element 32 can be made of an elastic material and be brought into contact with the other side of the brake disc 40. The second friction element 32 is connected to the second backing plate 31 such that it faces the other side of the brake disc 40.

[0040] The brake pad guide extension body 410 extends horizontally from the brake pad guide body 100 and is inserted into a second mounting groove 31b of the second carrier plate 31 such that it comes into contact with the second carrier plate 31. The brake pad guide extension body 410 is elastically deformed and inclined at a predetermined angle when it comes into contact with the second carrier plate 31.

[0041] The brake pad guide contact part 420 is in contact with the second carrier plate 31 and extends from the brake pad guide extension body 410 towards the second friction element 32 of the second brake pad 30 such that it is bent at a predetermined angle. The second friction element 32 has a second coupling groove 32a formed in its central region, and the brake pad guide contact part 420 is inserted into the second coupling groove 32a and is in contact with the second carrier plate 31.

[0042] Referring to the Fig. 8A and Fig. 8B is an angle θ1 between the brake pad guide contact part 420 and the brake pad guide extension body 410 greater than 90°. When it is brought into contact with the second support plate 31, the brake pad guide contact part 420 is elastically deformed and brought into surface contact with the second support plate 31. More precisely, an angle θ2 between the brake pad guide contact part 420 and a lower surface 31c of the second mounting groove 31b formed in the second support plate 31 can be set to 90°. The brake pad guide contact part 420 can thus be brought into surface contact with the second support plate 31 such that the brake pad guide extension part 400 stably supports the second brake pad 30.

[0043] The second reset indicator part 430 extends from one end of the brake pad guide contact part 420 towards the brake pad guide reset part 300 such that it is bent at a predetermined angle. When the second friction element 32 is worn, the second reset indicator part 430 comes into contact with the brake disc 40 and produces a noise to inform the driver that it is time to replace the second brake pad 30. Thus, the driver can recognize when it is time to replace the second brake pad 30.

[0044] The two brake pad guide support parts 200 each have two brake pad guide support bodies 210 and two brake pad guide mounting parts 220. The two brake pad guide support bodies 210 extend from both ends of the brake pad guide body 100 such that they are bent towards the two pin elements 10 and each supports one of the two pin elements 10. More precisely, the two brake pad guide support bodies 210 extend from both ends of the brake pad guide body 100 such that they are bent towards the two pin elements 10 and are located below the two pin elements 10 (based on the Fig. 3 and 9 to 11) and the undersides of the two pen elements 10 support (based on the Fig. 3 and 9 to 11).

[0045] The two brake pad guide mounting parts 220 extend from the two brake pad guide support bodies 210 in such a way that they are each bent in the direction of the two pin elements 10. The two brake pad guide mounting parts 220 are in contact with the upper surfaces of each of the two pin elements 10 (based on the Fig. 3 and 9 to 11). Thus, the pin element 10 can be stably attached between the brake pad guide support body 210 and the brake pad guide mounting part 220. The brake pad guide 2 for a brake device according to the embodiment of the present disclosure can therefore not only be stably coupled to the two pin elements 10, but also prevented from moving upwards on the two pin elements 10, thereby effectively preventing rattling noises.

[0046] The following describes the operating mode and effect of the brake pad guide 2 for a brake device according to the embodiment of the present disclosure with reference to the Fig. 9, Fig. 10 to Fig. 11 described.

[0047] When a driver presses the (not shown) brake pedal, the pressure element 50 presses the first brake pad 20 against the brake disc 40 (see Fig. 9 and Fig. 10) In this way, the first and second brake pads 20 and 30 can be pressed against the brake disc 40 and generate a braking force through friction. The second brake pad guide return element 320 of the brake pad guide return element is elastically deformed by the pressed first brake pad 20.

[0048] When the brake pedal is released, the pressure element 50 is separated from the first brake pad 20, and the elastic restoring force of the second brake pad guide reset element 320 of the brake pad guide reset element 300 returns the first brake pad 20 such that the first brake pad 20 is sufficiently separated from the brake disc 40. In this way, the first and second brake pads 20 and 30 are separated from the left and right sides of the brake disc 40 (based on the Fig. 9 and Fig. 10) Since the first and second brake pads 20 and 30 are sufficiently separated from the brake disc 40, it is possible to prevent drag torques which are generated by the contact friction between the first and second brake pads 20 and 30 and the brake disc 40.

[0049] If the first friction element 22 of the first brake pad 20 and the second friction element 32 of the second brake pad 30 are worn down by a preset thickness or more due to prolonged use of the brake, the first reset indicator part 330 of the brake pad guide reset part 300 and the second reset indicator part 430 of the brake pad guide extension part 400 can come into contact with the brake disc 40 when the first and second brake pads 20 and 30 are moved towards the brake disc 40. The driver may therefore experience difficulties in the operation of the first and second brake pads 20 and 30, and thus recognize when it is time to replace them. In this process, the first reset indicator part 330 of the brake pad guide reset part 300 and the second reset indicator part 430 of the brake pad guide extension part 400 can come into contact with the brake disc 40 and generate noise (they Fig.11) In this way, the driver can recognize the time for replacing the first and second brake pads 20 and 30 and quickly replace the first and second brake pads 20 and 30.
