Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile braking, in particular to a floating double-cylinder brake caliper. Background Art
[0002] The floating twin-cylinder brake caliper is an important component used in automobile braking systems. The floating twin-cylinder brake caliper means that there are two pistons (twin-cylinders) inside the brake caliper, and the entire caliper can float on the brake disc. When the brake pedal is stepped on, the brake fluid enters the brake caliper through the brake line, pushing the piston to clamp the brake pad on the brake disc, thereby achieving braking effect. The floating design can make the brake caliper apply force more evenly to the brake disc during braking, improving braking performance and stability. The twin-cylinder design can provide greater braking force and has better heat dissipation performance, which is suitable for high-speed braking situations. This design is commonly used in high-performance cars and racing cars to ensure that the braking effect is more reliable and stable.
[0003] For example, a Chinese patent discloses: a floating dual-cylinder brake caliper, patent number: CN217736096U, which improves the uneven pressure distribution of the friction pad by adjusting the diameter of the two cylinder holes, reduces the difference in contact pressure between the inlet and outlet ends, solves the problems of brake vibration, noise and brake pad eccentric wear caused by uneven pressure distribution, and improves the braking performance of the brake caliper product.
[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: As mentioned above, in an emergency situation, the driver will subconsciously step on the brake, causing the caliper and brake disc to lock directly, thereby performing emergency braking. However, this operation can easily cause the vehicle to roll over, making it difficult to ensure the driver's personal safety. Utility Model Content
[0005] (1) Technical problems solved

[0007] (2) Technical solution
[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:
[0009] A floating double-cylinder brake caliper comprises a caliper body, a braking mechanism is provided on the side wall of the caliper body, the braking mechanism comprises a first oil cylinder, a first telescopic rod, a second oil cylinder, the second telescopic rod, a first brake pad, a mounting ring, a brake disc, a bump and a shock-absorbing gasket, the first telescopic rod is slidably mounted inside the first oil cylinder, the second oil cylinder is fixedly mounted on the side wall of the caliper body, the second telescopic rod is slidably mounted inside the second oil cylinder, one end of the first telescopic rod and the second telescopic rod away from the first oil cylinder and the second cylinder is fixedly mounted on the shock-absorbing gasket, the side wall of the shock-absorbing gasket is fixedly mounted on the first brake pad, the mounting ring is fixedly mounted on the second telescopic rod and the side wall of the first telescopic rod, the brake disc is movably mounted inside the caliper body, and the bump is fixedly mounted on the side wall of the brake disc.

[0015] (3) Beneficial effects
[0016] 1. The first oil cylinder and the second oil cylinder will respectively push the first telescopic rod and the second telescopic rod to move toward the brake disc. The first telescopic rod is closer to the bump than the second telescopic rod, which can adapt to the thermal deformation of the brake disc to a certain extent, ensuring that the first brake pad can effectively contact the brake disc under different working conditions and maintain good braking performance. When emergency braking is performed, the first brake pad will quickly approach the brake disc. Since the side wall of the brake disc is provided with a bump, the first brake pad will intermittently contact the bump to prevent the device from directly locking. The contact between the first brake pad and the bump will generate vibration, which will be absorbed by the shock-absorbing gasket. The mounting ring will limit the first brake pad and the shock-absorbing gasket to prevent deviation, thereby increasing the braking effectiveness of the device.
[0017] 2. When the device is in operation, under the reaction force of the first telescopic rod and the second telescopic rod, the fixed column will contact the brake disc for auxiliary braking. At this time, the sliding column will retract into the fixed cylinder, causing the spring to be compressed, and the connecting column will extend from the inside of the sliding column. The connecting column will contact the brake disc to further assist braking. When the device is not working, the spring rebounds, causing the internal components of the device to quickly reset, reducing drag energy loss, reducing wear on the brake pads and brake discs, and increasing the service life of the brake pads.

[0025] Example
[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that when the driver is in an emergency, he will subconsciously step on the brake, causing the caliper and the brake disc to be directly locked, thereby performing emergency braking. However, this operation can easily cause the vehicle to roll over, making it difficult to ensure the driver's personal safety. The overall idea is as follows: A floating double-cylinder brake caliper includes a caliper body 11, and a braking mechanism is provided on the side wall of the caliper body 11. The braking mechanism includes a first oil cylinder 12, a first telescopic rod 13, a second oil cylinder 14, a second telescopic rod 15, a first brake pad 16, a mounting ring 17, a brake disc 27, a protrusion 28 and a shock-absorbing gasket 29. The first telescopic rod 13 is slidably installed in the first oil cylinder 12, and the second oil cylinder 14 is fixedly installed on the side wall of the caliper body 11. The second telescopic rod 15 is slidably installed in the second oil cylinder 14. The ends of the first telescopic rod 13 and the second telescopic rod 15 away from the first oil cylinder 12 and the second cylinder 14 are fixedly installed with the shock-absorbing gasket 29, and the side wall of the shock-absorbing gasket 29 is fixedly installed with the first brake pad 16. The mounting ring 17 is fixedly mounted on the sidewalls of the second telescopic rod 15 and the first telescopic rod 13. The brake disc 27 is movably mounted inside the caliper body 11. The protrusion 28 is fixedly mounted on the sidewall of the brake disc 27. The first cylinder 12 and the second cylinder 14 respectively push the first telescopic rod 13 and the second telescopic rod 15 toward the brake disc 27. The first telescopic rod 13 is closer to the protrusion 28 than the second telescopic rod 15. This can accommodate thermal deformation of the brake disc 27 to a certain extent, ensuring that the first brake pad 16 can effectively contact the brake disc under different operating conditions and maintain good braking performance. During emergency braking, the first brake pad 16 will quickly approach the brake disc 27. Due to the protrusion 28 provided on the sidewall of the brake disc 27, the first brake pad 16 will intermittently contact the protrusion 28 to prevent the device from directly locking. The contact between the first brake pad 16 and the protrusion 28 will generate vibration, which is absorbed by the shock-absorbing washer 29. The mounting ring 17 restrains the first brake pad 16 and the shock-absorbing washer 29 from deflecting, thereby increasing the braking effectiveness of the device.
[0027] The side walls of the first oil cylinder 12 and the second oil cylinder 14 are fixedly installed with a fixed cylinder 18, a spring 19 is inserted into the fixed cylinder 18, the spring 19 is fixedly installed with the fixed cylinder 18, a sliding column 22 is fixedly installed on the end of the spring 19 away from the fixed cylinder 18, a connecting column 21 is slidably installed inside the sliding column 22, the connecting column 21 is fixedly installed with the fixed cylinder 18, a mounting cylinder 23 is fixedly installed on the side wall of the caliper body 11, a fixed column 24 is fixedly installed inside the mounting cylinder 23, and when the device is in operation, the first telescopic rod 13 and the second telescopic rod 13 are connected to each other. Under the reaction force of the telescopic rod 15, the fixed column 24 will contact the brake disc 27 for auxiliary braking. At this time, the sliding column 22 will retract into the fixed cylinder 18, causing the spring 19 to be compressed, and the connecting column 21 will extend from the inside of the sliding column 22. The connecting column 21 will contact the brake disc 27 for further auxiliary braking. When the device is not working, the spring 19 rebounds, causing the internal components of the device to quickly reset, reducing drag energy loss, reducing wear on the brake pads and brake disc 27, and increasing the service life of the brake pads.
[0028] A second brake pad 25 is fixedly mounted on one end of the fixing column 24 away from the mounting tube 23 . A heat dissipation hole 26 is opened on the side wall of the caliper body 11 . Overheating of the placement device may reduce the braking function.
[0029] In response to the problems existing in the prior art, the utility model provides a floating double-cylinder brake caliper. The first oil cylinder 12 and the second oil cylinder 14 will respectively push the first telescopic rod 13 and the second telescopic rod 15 to move toward the brake disc 27. The first telescopic rod 13 is closer to the protrusion 28 than the second telescopic rod 15, which can adapt to the thermal deformation of the brake disc 27 to a certain extent, ensuring that the first brake pad 16 can effectively contact the brake disc under different working conditions and maintain good braking performance. When emergency braking is performed, the first brake pad 16 will quickly approach the brake disc 27. Since the side wall of the brake disc 27 is provided with a protrusion 28, the first brake pad 16 will intermittently contact the protrusion 28 to prevent the device from directly locking. The contact between the first brake pad 16 and the protrusion 28 will generate vibration , the shock-absorbing gasket 29 will absorb vibration, and the mounting ring 17 will limit the first brake pad 16 and the shock-absorbing gasket 29 to prevent deviation, thereby increasing the effectiveness of the braking device. When the device is operating, under the reaction force of the first telescopic rod 13 and the second telescopic rod 15, the fixed column 24 will contact the brake disc 27 for auxiliary braking. At this time, the sliding column 22 will retract into the fixed cylinder 18, so that the spring 19 is compressed, and the connecting column 21 will extend from the inside of the sliding column 22. The connecting column 21 will contact the brake disc 27 for further auxiliary braking. When the device is not working, the spring 19 rebounds, so that the components inside the device are quickly reset, reducing the drag energy loss, reducing the wear of the brake pad and the brake disc 27, and increasing the service life of the brake pad.
[0030] Working principle:
[0031] In the first step, when braking, the first oil cylinder 12 and the second oil cylinder 14 will respectively push the first telescopic rod 13 and the second telescopic rod 15 to move toward the brake disc 27. The first telescopic rod 13 is closer to the protrusion 28 than the second telescopic rod 15, which can adapt to the thermal deformation of the brake disc 27 to a certain extent, ensuring that the first brake pad 16 can effectively contact the brake disc under different working conditions and maintain good braking performance. When emergency braking is performed, the first brake pad 16 will quickly approach the brake disc 27. Because the side wall of the brake disc 27 is provided with a protrusion 28, the first brake pad 16 will intermittently contact the protrusion 28 to prevent the device from directly locking. The contact between the first brake pad 16 and the protrusion 28 will generate vibration, and the shock-absorbing gasket 29 will absorb the vibration. The mounting ring 17 will limit the first brake pad 16 and the shock-absorbing gasket 29 to prevent deviation, thereby increasing the effectiveness of the device's braking.
[0032] In the second step, when the device is operating, under the reaction force of the first telescopic rod 13 and the second telescopic rod 15, the fixed column 24 will contact the brake disc 27 for auxiliary braking. At this time, the sliding column 22 will retract into the fixed cylinder 18, causing the spring 19 to be compressed, and the connecting column 21 will extend from the inside of the sliding column 22. The connecting column 21 will contact the brake disc 27 for further auxiliary braking. When the device is not working, the spring 19 rebounds, causing the internal components of the device to quickly reset, reducing drag energy loss, reducing wear on the brake pads and brake disc 27, and increasing the service life of the brake pads.
