[0001] Cross-references to related applications

[0002] This application is based on and claims priority to Korean Patent Application No. 10-2020-0001047, filed with the Korean Intellectual Property Office on January 3, 2020, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure relates to a caliper brake, and more particularly, to a caliper brake configured to allow a caliper housing having a simple structure to slide. Background Technology

[0004] A typical caliper brake includes: a disc that rotates with the vehicle's wheels; a bracket on which a pair of pads are mounted to move forward and backward to compress the disc; a housing having a cylinder slidably mounted on the bracket and a piston mounted in the cylinder to move forward and backward by hydraulic pressure via a brake fluid such as brake oil; a spindle unit configured to compress the piston; a motor; and a reducer as an actuator to transmit rotational force to the spindle unit, etc.

[0005] The caliper brake performs braking by using the hydraulic compression piston of the braking fluid, or by using the nut component and main shaft component of the main shaft unit and by using the compression piston to convert the rotational force provided by the motor into linear motion.

[0006] In traditional caliper brakes, lugs are located at opposite ends of the housing. Each lug has a guide rod that allows the housing to be slidably connected to a bracket, and sliding holes corresponding to the guide rod's position are respectively located on opposite sides of the bracket. Therefore, the housing requires a relatively complex structure for slidable connection to the bracket and necessitates separate components such as the guide rod, which is disadvantageous in terms of component and production costs.

[0007] As an example of a conventional caliper brake, Korean Patent Publication No. 10-2015-0128273 (published on November 18, 2015) has been published. Summary of the Invention

[0035] The following embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The following embodiments are provided by way of example so that those skilled in the art will be able to carry out the idea of the present disclosure completely. The present disclosure is not limited to the following embodiments, but can be implemented in other forms. In order to clearly explain the present disclosure, parts irrelevant to the description are omitted from the accompanying drawings, and the width, length, thickness, etc. of components can be exaggerated for convenience.

[0036] As Figures 1 to 3As shown, the caliper brake according to the embodiment of the disclosure includes a bracket 40 on which a pair of pads 20 and 30 composed of an inner pad 20 and an outer pad 30 are mounted to advance and retreat in forward and backward directions; a caliper housing 100 slidably mounted on the bracket 40 and provided with a cylinder part 141 in which a piston (not shown) is installed to advance and retreat by brake hydraulic pressure, a finger part 123 bent downward to press the outer pad 30, and a body part 121 connecting the cylinder part 141 and the finger part 123. The body part 121 can be configured to surround opposite side ends of the bracket 40 and provided with a guide part 122 for guiding the caliper housing 100 to slide on the bracket 40.

[0037] The pair of pads 20 and 30 is composed of the inner pad 20 provided to be in contact with the piston and the outer pad 30 provided to be in contact with the finger part 123 of the caliper housing 100. The pair of pads 20 and 30 is mounted on the bracket 40 fixed to a vehicle body to advance toward and retreat from opposite sides of a disc (not shown) and friction pads 11 and 12 are attached to inner surfaces of the pair of pads 20 and 30, respectively, to be in friction with the disc. The disc rotating together with a wheel can be provided in a space D between the pair of friction pads 11 and 12 in Figure 5 the vehicle body and the pair of pads 20 and 30 attached to the pair of pads 20 and 30 press or release the disc by advancing toward or retreating from the opposite sides of the disc.

[0038] The caliper housing 100 is slidably mounted on the bracket 40. More particularly, the caliper housing 100 can include the cylinder part 141 located at a rear portion of the caliper housing 100 and in which the piston is installed to advance and retreat, the finger part 123 located at a front portion of the caliper housing 100 and molded to be bent to operate the outer pad 30, and the body part 121 connecting the cylinder part 141 and the finger part 123.

[0039] The caliper housing 100 can be configured by the cylinder part 141, the finger part 123, and the body part 121 integrally molded. However, the disclosure is not limited thereto, and as described below, the caliper housing 100 can be composed of a first caliper housing 120 and a second caliper housing 140 separately molded and then coupled by a fastening member B.

[0040] The cylindrical member 141 of the caliper housing 100 can be provided with a hydraulic chamber 143 into which a piston can be inserted. An oil port (not shown) through which brake oil is introduced can be formed on one side of the caliper housing 100 so that hydraulic pressure for braking can be applied to the hydraulic chamber 143 within the cylindrical member 141. Thus, brake oil can be introduced through the oil port to press the piston, the inner pad plate 20 in contact with the piston can be pressed toward the disc, and the outer pad plate 30 in contact with the finger member 123 can be pulled toward the disc. Thus, the inner pad plate 20 and the outer pad plate 30 can press the disc by advancing toward opposite sides of the disc or release the disc by retreating from opposite sides of the disc.

[0041] The cylindrical member 141 can be provided with a sealing member (not shown) to maintain airtightness so that brake oil does not leak between the inner peripheral surface of the cylindrical member 141 and the outer peripheral surface of the piston when the piston is inserted into the hydraulic chamber 143.

[0042] The piston is formed in a hollow shape and can be slidably disposed in the hydraulic chamber 143 of the cylindrical member 141. In particular, the piston can advance and retreat in the hydraulic chamber 143 by a power transmission unit (not shown) that receives power from a driving device (not shown). Thereby, the piston can press the inner pad plate 20 toward the disc to perform braking. The power transmission unit converts rotational motion into linear motion by receiving power from a driving device composed of a motor (not shown) and a reducer (not shown), and can include a main shaft member (not shown) and a nut member (not shown) configured to cause the piston to press and release the inner pad plate 20. The reducer can reduce power generated by the motor and transmit the power to the power transmission unit and can be configured in various structures such as a planetary gear assembly. A coupling hole 145 can be formed through one side of the rear portion of the cylindrical member 141 so as to provide a space for connecting the driving device and the power transmission unit.

[0043] The body member 121 is configured to connect the cylindrical member 141 and the finger member 123. The body member 121 of the caliper housing 100 can have a wide plate shape to cover the upper portion of the bracket 40. A guide member 122 can be formed on one side of the body member 121. The guide member 122 is configured to surround opposite side ends of the bracket 40 and can guide the caliper housing 100 to slide on the bracket 40.

[0044] In more detail, the bracket 40 includes a main beam 44 provided with a knuckle hole 45 coupled to a vehicle body and a pair of connection beams 42 provided on opposite sides of the main beam 44 to be on opposite sides to support a pair of pad plates 20 and 30, respectively, on opposite sides. The guide member 122 can be configured to extend from the lower side of the body member 121 toward the connection beams 42 of the bracket 40 to surround opposite sides of the connection beams 42.

[0045] The connecting beam 42 may be provided with a sliding member 43 that contacts the guide member 122. The sliding member 43 may be provided with a shape corresponding to the guide member 122. While the guide member 122 is in contact with the sliding member 43 of the bracket 40, the main body member 121 of the clamp housing 100 may slide forward and backward on the sliding member 43 of the bracket 40.

[0046] Therefore, when the piston presses the inner pad 20, the clamp housing 100 slides backward on the sliding member 43 of the bracket 40 due to the reaction force, and the finger member 123 slides backward together, thereby pressing the outer pad 30, which is in contact with the finger member 123, toward the disc. When the piston releases the inner pad 20, the clamp housing 100 slides forward on the sliding member 43 of the bracket 40, and the finger member 123 slides forward together on the sliding member 43, thereby releasing the outer pad 30, which is in contact with the finger member 123, from the disc.

[0047] More in detail, such as Figure 4 As shown, the sliding member 43 can protrude upward from the upper surface of the connecting beam 42 of the bracket 40, thereby forming a step. That is, the sliding member 43 can protrude upward from the inner side of the upper surface of the connecting beam 42 near the center of the bracket 40, thereby forming a step with the non-protruding part of the upper surface of the connecting beam 42. The lower side of the guide member 122 of the clamp housing 100 can contact the non-protruding part of the upper surface of the connecting beam 42, and the inner surface of the guide member 122 facing the center of the bracket 40 can contact the protruding outer surface of the sliding member 43.

[0048] Because the disc rotates together with the wheel, when a pair of pads 20 and 30 grip the opposite sides of the disc using friction, the pads 20 and 30 press against the bracket 40 by friction. This generates a force that presses against the bracket 40 along the direction of disc rotation, and the bracket 40 may deform or be damaged by repeated braking operations. Because the guide member 122 covers the opposite sides of the connecting beam 42 of the bracket 40 to support the bracket 40, the caliper brake of this disclosure can prevent deformation of the bracket 40. That is, when the bracket 40 is pressed by the pair of pads 20 and 30, the guide member 122 can support the bracket 40, thereby preventing excessive deformation of the bracket 40.

[0049] like Figure 7 and Figure 8As shown, the sliding member 43 can include a protruding portion 43b protruding upward from an upper surface of the connecting beam 42, and a curved portion 43a curved outward from the bracket 40 from the protruding portion 43b. The guide member 122 can include an extending portion 122a extending downward from the main body member 121, and an insertion portion 122b curved inward from the main body member 121 from the extending portion 122a to be inserted between the lower surface of the curved portion 43a and the upper surface of the connecting beam 42 by being curved inward from the extending portion 122a to the main body member 121. The insertion portion 122b of the guide member 122 is inserted between the curved portion 43a of the sliding member 43 and the upper surface of the connecting beam 42 and can prevent the plier housing 100 from being separated from the upper side of the bracket 40 when the plier housing 100 is mounted on the bracket 40. That is, the upper end of the insertion portion 122b of the guide member 122 can be supported by the lower end of the curved portion 43a of the sliding member 43. Also, since the extending portion 122a of the guide member 122 is configured to surround the outer side and the upper side of the curved portion 43a of the sliding member 43, the guide member 122 can support the bracket 40 when the bracket 40 is pressed by the pair of pads 20 and 30, so that the bracket 40 can be prevented from being excessively deformed.

[0050] The connecting beam 42 of the bracket 40 can be provided with a sliding groove 41 in which the protrusions 21 and 31 formed on the opposite sides of the pair of pads 20 and 30 are inserted. In more detail, a pair of sliding grooves 41 can be provided at the front and rear of the connecting beam 42, respectively. The protrusion 31 of the outer pad 30 can be slidably coupled to the sliding groove 41 formed at the front of the connecting beam 42, and the protrusion 21 of the inner pad 20 can be slidably coupled to the sliding groove 41 formed at the rear of the connecting beam 42.

[0051] The sliding groove 41 of the present disclosure can be provided by a groove-shaped space formed between an upper flange 41a protruding from the connecting beam 42 of the bracket 40 and a lower flange 41b protruding from below the upper flange 41a. However, the sliding groove 41 does not necessarily need to include the upper flange 41a and the lower flange 41b protruding as shown, and the sliding groove 41 can have various structures as long as a space in which the protrusions 21 and 31 of the pads 20 and 30 can slide is provided.

[0052] The caliper brake of the present disclosure can further include a first flange 124 provided on the finger members 123. The first flange 124 can protrude to be inserted into the sliding groove 41 of the bracket 40 and advance and retreat in the sliding groove 41. The first flange 124 is formed to extend outward from each of the pair of finger members 123, and the extended first flange 124 can be disposed between the upper and lower flanges 41a and 41b of the sliding groove 41 provided at the front of the connecting beam 42 of the bracket 40. Accordingly, the upper and lower portions of the first flange 124 of the finger members 123 can be supported by the upper and lower flanges 41a and 41b of the connecting beam 42, respectively. The first flange 124 of the finger members 123 can slide together in the sliding groove 41 of the bracket 40 when the caliper housing 100 slides by braking and releasing the brake.

[0053] The finger members 123 can be formed to be bent downward from the main body member 121, and a pair of finger members 123 can be provided as shown in the drawings. However, the present disclosure is not limited to the provision of a pair of finger members 123, and one finger member 123 or three or more finger members 123 can be provided. When one finger member 123 is provided, the first flange 124 can be formed to extend to the opposite side of the finger member 123, and when three or more finger members 123 are provided, a pair of first flanges 124 can be formed to extend outward from the outermost sides of the finger members 123, respectively.

[0054] The caliper brake of the present disclosure can further include a second flange 142 provided on the cylindrical member 141. The second flange 142 protrudes to be inserted into the sliding groove 41 of the bracket 40 and advance and retreat in the sliding groove 41. The second flange 142 is formed to extend outward from the cylindrical member 141, and the extended second flange 142 can be disposed between the upper and lower flanges 41a and 41b of the sliding groove 41 provided at the rear of the connecting beam 42. Accordingly, the upper and lower portions of the second flange 142 of the cylindrical member 141 can be supported by the upper and lower flanges 41a and 41b of the connecting beam 42, respectively. The second flange 142 of the cylindrical member 141 can slide together in the sliding groove 41 of the bracket 40 when the caliper housing 100 slides by braking and releasing the brake.

[0055] The bracket 40 can include a main beam 44 provided with a knuckle hole 45 for fixing the bracket 40 to a vehicle body, and a connecting beam 42 connected to the main beam 44 and supporting a pair of pads 20 and 30, sliding grooves 41 in which protrusions 21 and 31 formed on opposite sides of the pair of pads 20 and 30 are inserted can be respectively provided at a front and a rear of the connecting beam 42, a finger member 123 can be provided with a first flange 124 formed to be inserted in the sliding groove 41 provided at the front of the connecting beam 42, and a cylindrical member 141 can be provided with a second flange 142 formed to be inserted in the sliding groove 41 provided at the rear of the connecting beam 42. The sliding grooves 41 respectively formed at the front and the rear of the connecting beam 42, the first flange 124, and the second flange 142 can be provided in parallel.

[0056] As shown in Figure 7 and Figure 8 The main body member 121 can include a support flange 125 inserted between the inner side of the connecting beam 42 of the bracket 40 and the outer side of the pair of pads 20 and 30 and protruding downward. In more detail, the support flange 125 can be configured such that one side thereof is supported by the inner side of the sliding member 43 and the other side thereof supports the outer side of the pads 20 and 30.

[0057] Accordingly, when the pads 20 and 30 are pressed and rotated by the disc, the protrusions 21 and 31 of the pads 20 and 30 can be supported by the sliding grooves 41, and the outer side of the upper portions of the pads 20 and 30 can be supported by the support flange 125. Accordingly, when the pads 20 and 30 are pressed in the direction of rotation of the disc, various load transmission paths can be formed, and the force with which the pads 20 and 30 press the bracket 40 is not concentrated on any one of the bracket 40, thereby preventing the bracket 40 from being deformed.

[0058] The pair of support flanges 125 can be arranged to be spaced apart from each other so as not to interfere with the disc. The pair of support flanges 125 are provided to face each other and can protrude from the main body member 121 to support the inner pad 20 and the outer pad 30, respectively. Unlike this, only one of the support flanges 125 can be provided, and in this case, the support flange 125 can protrude to support the inner pad 20 or can protrude to support the outer pad 30.

[0059] The main body member 121 can further include a rigidity reinforcing portion 126. The rigidity reinforcing portion 126 can be provided between the main body member 121 and the support flange 125. As shown in Figure 8 The rigidity reinforcing portion 126 can include a first reinforcing surface 126a formed to be inclined upward from the inner side of the support flange 125, and a second reinforcing surface 126b formed to be steeper than the first reinforcing surface 126a.

[0060] When the support flange 125 is provided to protrude downward from the main body part 121, the support flange 125 can be worn or deformed due to repeated pressing and releasing of the pads 20 and 30. However, the rigidity enhancement part 126 for enhancing coupling rigidity is provided between the inner side of the support flange 125 and the main body part 121, so that deformation of the support flange 125 can be prevented. The first and second enhancement surfaces 126a and 126b can support one side of the pads 20 and 30 according to various shapes of the pads 20 and 30, and can allow the force with which the pads 20 and 30 press the bracket 40 to be dispersed through various load transmission paths.

[0061] As described above, the caliper brake of the present disclosure can include a bracket 40 in which a pair of pads 20 and 30 composed of an inner pad 20 and an outer pad 30 are installed to advance and retreat, and a caliper housing 100 that is slidably installed on the bracket 40 and is provided with a cylinder part 141 in which a piston is installed to advance and retreat by brake hydraulic pressure, and a finger part 123 that is bent downward to press the outer pad 30, and the caliper housing 100 can be provided with a guide part 122 that supports opposite side ends of the bracket 40 to be slidable on the bracket 40. The caliper brake can further include flanges 124 and 142 provided on at least one of the finger part 123 and the cylinder part 141. That is, the finger part 123 can be provided with a first flange 124 that protrudes to be fastened to a sliding groove 41 formed at a front portion of the bracket 40, or the cylinder part 141 can be provided with a second flange 142 that protrudes to be fastened to a sliding groove 41 formed at a rear portion of the bracket 40. Also, the finger part 123 and the cylinder part 141 can be provided with the first flange 124 and the second flange 142, respectively, to be fastened to the sliding grooves 41 formed at the front and rear portions of the bracket 40.

[0062] The caliper brake of the present disclosure can further include a pad spring (not shown) that is inserted between the bracket 40 and the flanges 124 and 142. The pad spring can be fixed to the sliding groove 41 of the bracket 40 and can guide the flanges 124 and 142 of the pads 20 and 30 and the caliper housing 100 to smoothly slide. That is, the protrusions 21 and 31 of the pads 20 and 30 are inserted into the pad spring to facilitate smooth movement of the pads 20 and 30 and prevent the pads 20 and 30 from vibrating when the vehicle vibrates, and the pad spring can support the first flange 124 or the second flange 142 of the caliper housing 100 to smoothly slide in the sliding groove 41.

[0063] As described above, the caliper housing 100 of the present disclosure can be configured by the integrally molded cylindrical part 141, the finger part 123, and the main body part 121. Unlike this, as will be described later, the caliper housing 100 of the present disclosure can be composed of a separate first caliper housing 120 and a second caliper housing 140.

[0064] The caliper housing 100 can be composed of the first caliper housing 120 and the second caliper housing 140. In this case, the first caliper housing 120 can include the main body part 121 having opposite side ends to support the bracket 40 to the guide part 122 slidable on the bracket 40, and the finger part 123 bent downward from the main body part 121 to press the outer pad 30. The second caliper housing 140 can include the cylindrical part 141 in which the piston is installed to advance and retreat by brake hydraulic pressure. The bracket 40, the guide part 122, the main body part 121, the finger part 123, and the cylindrical part 141 are the same as described above, and thus the description thereof will be omitted.

[0065] The fastening member B can be provided to couple the first caliper housing 120 and the second caliper housing 140. In more detail, the first caliper housing 120 and the second caliper housing 140 can be respectively provided with the first through hole 125 and the second through hole 144 to which the fastening member B is fastened.

[0066] The pair of second through holes 144 can be provided at opposite sides of the cylindrical part 141 of the second caliper housing 140, and the fastening member B can be inserted into the second through holes 144. The first through hole 125 can be provided on the main body part 121 of the first caliper housing 120 to be coaxially placed with the second through hole 144, and the fastening member B can be inserted into the first through hole 125.

[0067] In more detail, the fastening member B is provided as a bolt and can be screwed to the first through hole 125 and the second through hole 144. That is, the fastening member B can have a threaded portion, and the first through hole 125 and the second through hole 144 can have a threaded portion corresponding to the shape of the threaded portion of the fastening member B.
