[0002] The brake is a device that has the function of slowing down, stopping or keeping the vehicle stopped. When the brake is first installed or repaired, a small amount of air will be mixed into the brake caliper.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] An embodiment of the present application provides a brake caliper, which has two co-linear exhaust pipes arranged on a shell, so that when the brake caliper is installed on the left and right sides of a vehicle, there is an exhaust pipe with an exhaust direction facing upward for exhaust, thereby improving the versatility of the brake caliper. The setting of the adjustment mechanism can adjust the exhaust direction of the exhaust pipe and improve the exhaust efficiency.

[0048] Reference Figure 1 , shows a front view of the brake caliper according to an embodiment of the present application, such as Figure 1As shown, the brake caliper may specifically include: a caliper body 12, a housing 11 and an adjustment mechanism 13; the caliper body 12 and the housing 11 together form the main body 10 of the brake caliper, wherein the housing 11 is rotatably connected to the caliper body 12 and encloses the caliper body 12 to form an oil filling chamber 30. The housing 11 is also provided with an oil filling hole 111, which is in communication with the oil filling chamber 30 and is used to connect an oil filling pipe.

[0049] In a specific application, the oil filling chamber 30 is used for injecting brake oil. A piston 70 is provided in the caliper body 12. The brake oil enters the oil filling chamber 30 through the oil filling pipe. The oil pressure in the oil filling chamber 30 increases, which can push the piston 70 of the brake caliper to move and produce a braking effect on the vehicle.

[0050] The housing 11 is also provided with two co-linear exhaust pipes 20, one end of the exhaust pipe 20 is connected to the oil filling chamber 30, and the other end is connected to the external atmosphere. The oil filling chamber 30 is connected to the external atmosphere through the exhaust pipe 20. Figures 2 to 3 As shown, a sealing nail 21 is also provided at one end of the exhaust pipe 20 away from the oil filling chamber 30. In practical applications, after the brake caliper is installed on the vehicle, the sealing nail 21 of the exhaust pipe 20 with the exhaust direction facing downward can be first locked according to the positions of the two exhaust pipes 20, and then the sealing nail 21 on the exhaust pipe 20 with the exhaust direction facing upward can be loosened, and then the oil filling pipe can be installed on the oil filling hole 111 for oil filling. When a large amount of brake oil appears in the exhaust pipe 20, the sealing nail 21 is locked. At this time, the oil will push the piston 70 to slide in the steel sleeve 60, and the exhaust is completed. After locking the sealing nail 21, the exhaust pipe 20 can be sealed, thereby preventing external gas from entering the oil filling chamber 30 again.

[0051] The adjusting mechanism 13 is fixedly connected to the housing 11 and the caliper body 12, respectively, and is used to drive the housing 11 to rotate around the caliper body 12. After the brake caliper is installed on the vehicle, the position of the caliper body 12 is fixed. When the adjusting mechanism 13 drives the housing 11 to rotate around the caliper body 12, the positions of the two exhaust pipes 20 fixedly connected to the housing 11 change accordingly, so that the exhaust direction of the exhaust pipes 20 can also change accordingly.

[0052] It should be noted that, since the installation positions of the brake calipers of different models may be different, the position design of the exhaust pipe 20 on a certain brake caliper, when the brake caliper is installed on vehicles of different models, the exhaust direction of the two exhaust pipes 20 may have a small angle with the horizontal direction, and it may even happen that the exhaust directions of the two exhaust pipes 20 are both in the horizontal direction, which is not conducive to the discharge of air in the oil filling chamber 30. When the exhaust direction of the exhaust pipe 20 is not good and affects the exhaust efficiency and effect, the housing 11 can be driven to rotate by the adjustment mechanism 13 to make the exhaust pipe 20 rotate accordingly, and the exhaust direction of the exhaust pipe 20 can be adjusted to ensure the exhaust efficiency of the exhaust pipe 20. Preferably, the exhaust direction of the exhaust pipe 20 can be adjusted to be more than ° upward.

[0053] In practical applications, the exhaust pipe 20 can be used for the initial installation and maintenance of the brake caliper. The caliper body 12 and the shell 11 serve as the main structural body of the brake caliper and are used to cooperate with the steering knuckle of the vehicle to produce a braking effect on the vehicle. The two exhaust pipes 20 are connected to the outer wall of the shell 11 and are used for exhaust; wherein the exhaust pipe 20 has an air inlet end and an air outlet end that are arranged in opposite directions, and the exhaust direction of the exhaust pipe 20 is from the air inlet end to the air outlet end; the brake caliper is provided with an oil filling chamber 30, the two exhaust pipes 20 are fixedly connected to the shell 11, and the air inlet ends of the two exhaust pipes 20 are both connected to the oil filling chamber 30, the exhaust directions of the two exhaust pipes 20 are opposite, and the exhaust direction of one exhaust pipe 20 is upward, and the exhaust direction of the other exhaust pipe 20 is downward.

[0054] It should be noted that according to a large number of tests, when the exhaust direction of the exhaust pipe 20 is at an angle greater than ° with the horizontal direction, exhaust is fastest. Therefore, when designing the exhaust pipe 20 of the brake caliper for a certain vehicle model, setting the exhaust direction to be upward at an angle greater than ° is the optimal exhaust direction. It can be understood that when the exhaust direction of one exhaust pipe 20 is optimal when the brake caliper is installed on one side of the vehicle, when the brake caliper is installed on the other side of the vehicle, since the exhaust direction of the other exhaust pipe 20 is opposite to it, it can be ensured that the exhaust direction of the other exhaust pipe 20 is also optimal, exhaust is fastest, and the effect is best.

[0055] In an optional embodiment of the present application, the inner wall of the exhaust pipe 20 is tangent to the cavity wall of the oil injection cavity 30 .

[0056] In actual applications, the diameter of the exhaust pipe 20 is relatively small. When the inner wall of the exhaust pipe 20 is tangent to the wall of the oil injection chamber 30, the air in the oil injection chamber 30 can enter the exhaust pipe 20 along the tangent line between the inner wall of the exhaust pipe 20 and the wall of the oil injection chamber 30, thereby avoiding a large angle between the air inlet end of the exhaust pipe 20 and the wall of the oil injection chamber 30, so that the exhaust can be smoother.

[0057] Reference Figure 4, shows one of the partial cross-sectional views of the brake caliper according to the embodiment of the present application, Figure 5 for Figure 4 The enlarged schematic diagram of part B in the middle. Figure 4 and Figure 5 As shown, the adjustment mechanism 13 includes a first adjustment component 14, a second adjustment component 15 and a driving component 16; wherein the first adjustment component 14 is fixedly connected to the shell 11, the second adjustment component 15 is fixedly connected to the caliper body 12, one end of the driving component 16 is fixedly connected to the first adjustment component 14, and the other end is movably connected to the second adjustment component 15, and the driving component 16 is used to drive the first adjustment component 14 to move closer to or away from the second adjustment component 15, so as to drive the shell 11 to rotate around the caliper body 12.

[0058] Since the second adjusting component 15 is fixedly connected to the caliper body 12, and the position of the caliper body 12 is determined after the brake caliper is installed, when one end of the driving component 16 movably connected to the second adjusting component 15 moves relative to the second adjusting component 15, it can drive the first adjusting component 14 fixedly connected to the other end thereof to move closer to or away from the second adjusting component 15, so that the first adjusting component 14 can drive the shell 11 to move around the caliper body 12 to change the exhaust direction of the exhaust pipe 20 fixedly connected to the shell 11.

[0059] In an optional embodiment of the present application, the driving assembly 16 includes an adjusting rod 161 and a first fastener 162, such as Figure 4 As shown, one end of the adjustment rod 161 is fixedly connected to the first adjustment component 14 , and the other end is passed through the second adjustment component 15 and movably connected to the first fastener 162 . The first fastener 162 is arranged on the side of the second adjustment component 15 away from the first adjustment component 14 .

[0060] Specifically, the adjusting rod 161 passes through the second adjusting component 15 and can move in the second adjusting component 15. Since the first fastener 162 is movably connected to the adjusting rod 161, the relative position of the first fastener 162 and the adjusting rod 161 can be adjusted to drive the adjusting rod 161 to move in the second adjusting component 15, so that the adjusting rod 161 drives the first adjusting component 14 to move closer to or away from the second adjusting component 15, so that the shell 11 can rotate around the clamp body 12 to change the exhaust direction of the exhaust pipe 20.

[0061] Furthermore, the adjusting rod 161 may be a stud, and the first fastener 162 may be a nut matched with the stud, and the stud and the nut are threadedly connected.

[0062] In practical applications, the specifications and sizes of the stud and nut can be selected according to the specific structure of the brake caliper. When the exhaust direction of the exhaust pipe 20 needs to be adjusted, the nut can be rotated with a tightening wrench, and the rotation of the nut drives the stud to drive the first adjustment component 14 to move closer to the second adjustment component 15, thereby adjusting the exhaust direction of the exhaust pipe 20. This adjustment method has a relatively simple structure, is easy to produce and operate, and the nut is threadedly connected to the stud, which can maintain the position of the first adjustment component 14, and then the position of the housing 11 and the caliper body 12 is also fixed.

[0063] In an optional embodiment of the present application, the first adjusting component 14 includes a first steel ball 142 and two first brackets 141; wherein, the two first brackets 141 are spaced apart along the first direction and fixedly connected to the shell 11, and the first steel ball 142 can be embedded between the two first brackets 141 after interference fitting so as to be movably connected to the two first brackets 141; one end of the driving component 16 is fixedly connected to the first steel ball 142; the second adjusting component 15 includes a second bracket 151 and a second steel ball 152; wherein, the second bracket 151 is fixedly connected to the caliper body 12, and a limiting through hole is provided, and the second steel ball 152 can be embedded in the limiting through hole after interference fitting so as to be movably connected to the second bracket 151.

[0064] Optionally, the inner wall of the limiting through hole has an arc that matches the outer wall of the second steel ball 152. After the second steel ball 152 is interference-fitted into the limiting through hole, it is embedded in the limiting through hole. Since the arc of the inner wall of the limiting through hole matches the outer wall of the second steel ball 152, the second steel ball 152 can rotate; the direction of the limiting through hole of the second bracket 151 is consistent with the extension direction of the stud, so that when the second steel ball 152 is movably connected to the limiting through hole, conditions can be provided for the stud to pass through the second steel ball 152.

[0065] In the embodiment of the present application, a groove is provided on one side of the first bracket 141 close to the first steel ball 142 , and the first steel ball 142 is respectively embedded in the grooves of the two first brackets 141 on both sides along the first direction to be movably connected with the two first brackets 141 .

[0066] Specifically, the distance between the grooves of the two first brackets 141 along the first direction is greater than the diameter of the first steel ball 142. After the first steel ball 142 is pressed between the two first brackets 141, there may be a distance between the first steel ball 142 and the grooves of the two first brackets 141. This distance provides adjustment space for the height difference between the first steel ball 142 and the second steel ball 152.

[0067] Since the first steel ball 142 is indirectly connected to the shell body 11, and the second steel ball 152 is indirectly connected to the caliper body 12, the height of the second steel ball 152 is actually immutable, and the exhaust shell is rotatably connected to the caliper body 12. When the exhaust shell rotates relative to the caliper body 12, the first steel ball 142 and the second steel ball 152 may not be on the same horizontal plane. Therefore, the first steel ball 142 is arranged between the two first brackets 141 and movably connected to the two first brackets 141, so that the height of the first steel ball 142 can be changed, thereby avoiding the problem of the stud getting stuck when the shell 11 rotates around the caliper body 12 and causes the first steel ball 142 and the second steel ball 152 to be non-coplanar.

[0068] In the embodiment of the present application, a first limiting protrusion 155 is provided on the outer surface of the second steel ball 152, and a first limiting groove 154 adapted to the first limiting protrusion 155 is provided on the inner surface of the limiting through hole of the second bracket 151. The first limiting protrusion 155 is embedded in the first limiting groove 154 to limit the rotation angle of the second steel ball 152 in the limiting through hole.

[0069] Specifically, the first limiting groove 154 has the same curvature as the second steel ball 152, the length direction of the first limiting groove 154 is close to the extension direction of the stud, and both ends of the first limiting groove 154 are located in the limiting through hole, so that the first limiting groove 154 can provide a limiting effect for the first limiting protrusion 155, ensuring that the first limiting protrusion 155 slides in the first limiting groove 154, thereby limiting the rotation angle of the second steel ball 152 in the limiting through hole, making it convenient for the stud to pass through the second steel ball 152.

[0070] Furthermore, a rolling gear 153 is provided at one end of the second steel ball 152 close to the nut, and the nut is also provided with teeth 163 meshing with the rolling gear 153. A rubber spring is also sleeved on the stud between the first steel ball 142 and the second steel ball 152. When a tightening wrench is used to rotate the nut to move the first steel ball 142 close to the second steel ball 152, the distance between the second steel ball 152 and the first steel ball 142 becomes shorter and shorter, thereby compressing the rubber spring. Under the restoring force of the rubber spring, the stud has a tendency to move away from the second steel ball 152. At this time, the rolling gear 153 and the teeth 163 are locked, and the position between the exhaust housing and the caliper body 12 is fixed.

[0071] Reference Figure 6 , showing a third partial cross-sectional view of the brake caliper according to an embodiment of the present application, Figure 7 for Figure 6 The enlarged schematic diagram of the middle C part, refer to Figure 8 , showing a fourth partial cross-sectional view of the brake caliper according to an embodiment of the present application, Fig. 9 for Figure 8 The enlarged schematic diagram of the middle D part is as follows: Figures 6 to 9As shown, the brake caliper further includes a sealing sleeve 40 , one end of which along the second direction is clamped with the caliper body 12 , and the other end of which is threadedly connected with the housing 11 .

[0072] Specifically, the cross section of the sealing sleeve 40 is L-shaped, and the upper end of the sealing sleeve 40 has an external thread, such as Fig.10 As shown, the lower end of the sealing sleeve 40 is provided with a plurality of tooling limiting grooves 42, and the plurality of tooling limiting grooves 42 are arranged at intervals along the circumference of the sealing sleeve 40 at the lower end of the sealing sleeve 40. In actual application, when the sealing sleeve 40 is assembled into the caliper body 12, an assembly tool can be used to embed the protrusion of the assembly tool into the tooling limiting groove 42, and the assembly tool is rotated, and the sealing sleeve 40 rotates synchronously therewith and is assembled into the caliper body 12, as shown in FIG. Fig.12 The figure shows the matching diagram of the sealing sleeve 40 and the caliper body 12 after the assembly is completed. The position where the caliper body 12 is connected to the sealing sleeve 40 is set to a shape that matches the sealing sleeve 40, so that the lower end of the sealing sleeve 40 can be clamped to the caliper body 12; the brake caliper also includes a steel sleeve 60 and a piston 70. The steel sleeve 60 is assembled in the caliper body 12 by interference fit, so that the sealing sleeve 40 is sleeved on the outer wall of the upper end of the steel sleeve 60, and the piston 70 is assembled in the steel sleeve 60 by interference fit. In actual application, since the housing 11 and the caliper body 12 are connected in rotation, the sealing sleeve 40 can ensure the sealing effect between the housing 11 and the caliper body 12.

[0073] In the embodiment of the present application, the brake caliper further includes a sealing gasket 50 , which is disposed between the housing 11 and the sealing sleeve 40 .

[0074] In actual application, when assembling the brake caliper, the sealing gasket 50 is first placed in the caliper body 12, and then the caliper body 12 is put on the sealing sleeve 40 and the sealing sleeve 40 is rotated until the shell 11 is screwed to the upper end of the sealing sleeve 40, and then the shell 11 is rotated onto the sealing sleeve 40 using the existing external tooling until the required torque is reached. At this time, the rotation of the shell 11 is stopped. At this time, the sealing gasket 50 is clamped between the sealing sleeve 40 and the caliper body 12, thereby further ensuring the sealing of the sealing sleeve 40 and the caliper body 12.

[0075] In the present application embodiment, Fig.11 As shown, the inner wall of the caliper body 12 is provided with a second limiting groove 121 , the second limiting groove 121 is at least partially parallel to the circumference of the caliper body 12 , and the sealing sleeve 40 is provided with a second limiting protrusion 41 adapted to the second limiting groove 121 .

[0076] In actual applications, when the adjusting mechanism 13 is working, the shell 11 rotates around the caliper body 12, the sealing sleeve 40 rotates synchronously with the shell 11, and the second limiting protrusion 41 moves in the part of the second limiting groove 121 that is parallel to the circumference of the caliper body 12, so that the shell 11 can maintain horizontal movement relative to the caliper body 12, avoiding the problem of the sealing gasket 50 being squeezed and crushed, thereby ensuring the sealing effect.

[0077] The present application also discloses a brake assembly, which includes the above brake caliper.

[0078] In actual applications, the brake assembly also includes a steering knuckle, a wheel hub bearing, a caliper bracket, a brake disc, a brake fender and other structures. Among them, the brake caliper provided in this application will be installed on the suspension of the vehicle along with the brake assembly to produce a braking effect on the vehicle when the driver steps on the brake.

[0079] The present application also discloses a vehicle, which comprises the brake caliper as described above.

[0080] Since the brake caliper provided in the present application is provided with two exhaust pipes 20 with different exhaust directions, the brake caliper can be used on both sides of the vehicle, that is, the above brake caliper can be used on both the left and right sides of the vehicle provided in the present application.

[0081] It should be noted that the brake assembly and vehicle provided in the present application have the same technical effects as the above-mentioned brake caliper, which will not be described in detail here.

[0082] In summary, in the embodiment of the present application, the oil filling chamber formed by the shell and the caliper body can be used for the injection of brake oil to promote the piston movement of the brake caliper and produce a braking effect on the vehicle. Two co-linear exhaust pipes are arranged on the shell. When the brake caliper is initially installed and repaired, the two exhaust pipes are connected to the oil filling chamber, so the exhaust pipe can discharge the air in the oil filling chamber along its exhaust direction, reduce the influence of the air in the oil filling chamber on the vehicle's braking stroke, and ensure the braking effect; because the two exhaust pipes are arranged in a co-linear manner, it is equivalent to that the two exhaust pipes have opposite exhaust directions, so that when the brake caliper is installed on the left and right sides of the vehicle, there is an exhaust pipe with an exhaust direction facing upward for exhaust, and the sealing pin of one of the two exhaust pipes with an exhaust direction facing downward is locked, and the air in the oil filling chamber can be discharged through the other exhaust pipe; in this process, the setting of the adjustment mechanism can drive the shell to rotate to adjust the exhaust direction of the exhaust pipe, which can improve the smoothness and exhaust efficiency of the brake caliper exhaust. The brake caliper in the present application has high versatility, which is conducive to simplifying production and saving development costs and production costs. Moreover, since the brake calipers on the left and right sides are universal, the convenience and efficiency of the installation and maintenance of the brake caliper are improved.
