Description

Technical Field

[0001] The present invention relates to the technical field of brakes, and in particular to a floating caliper disc brake, especially a lightweight and wear-resistant floating caliper disc brake. Background Art

[0002] The caliper disc brake is a type of disc brake. Its rotating element is a metal disc that works on its end face, called the brake disc. The fixed element is a brake block composed of a friction block with a small working area and its metal back plate. There are 2 - 4 of these brake blocks in each brake, and these brake blocks and their actuating devices are all installed in a caliper-shaped bracket that straddles both sides of the brake disc, collectively called the brake caliper. The brake disc and the brake caliper together constitute the caliper disc brake, and the caliper disc brake can be divided into two types: fixed caliper disc brake and floating caliper disc brake. The brake caliper of the floating caliper disc brake is generally designed to be axially slidable relative to the brake disc, and the braking effect is achieved through the frictional force between the brake caliper and the brake disc.

[0003] After retrieval, a new type of floating caliper disc brake is disclosed in a Chinese patent document

Application No.: CN201320306862.8; Publication No.: CN203362904U

[0004] The device disclosed in this patent is simple and lightweight in structure during use, and the braking efficiency of the brake is less affected by the friction coefficient. However, during daily braking, due to the single braking structure, the frictional force during braking acts on the surface of the friction block. During long-term use, the friction block will be severely worn, resulting in a decrease in service life. And during use, since the friction block acts on the same position on the surface of the brake disc for a long time, a specific position of the brake pad will become thinner, and the gap between the friction block and the brake pad will become larger, and the travel of the friction block will become farther, resulting in a reduction in braking effect and prone to safety accidents. And since the braking system is an important line of defense for safety protection, during the use of this brake, its performance cannot be self-checked, reducing the practicality of this brake. Summary of the Invention

[0005] The object of the present invention is to address the above problems existing in the prior art and propose a lightweight and wear-resistant floating caliper disc brake. The lightweight and wear-resistant floating caliper disc brake enhances the wear resistance of the surface of the brake and is relatively lightweight as a whole through the settings of the floating caliper body and the top caliper, and also has a self-checking function. Under the action of the power mechanism, the top caliper moves towards the brake disc body, so that the action groove on the surface of the top caliper acts on the top of the brake disc body, sharing the acting force during the braking of the brake. Moreover, the staff can also use the adjusting mechanism to adjust the height of the brake, thereby changing the position of the braking part.

[0006] The object of the present invention can be achieved by the following technical solutions:

[0007] A lightweight and wear-resistant floating caliper disc brake, comprising a brake disc body and a floating caliper body. The brake disc body is movably arranged below the floating caliper body. Connectors are fixed on both sides of the surface of the floating caliper body, and connection sliders are fixed on the tops of the connectors. An outer shell is arranged on the top of the floating caliper body, and an adjusting mechanism is fixed in the inner cavity of the outer shell. A plurality of shells are fixed on the top of the floating caliper body, and a power mechanism is fixed in the inner cavity of the shell. A first chute is opened in the inner cavity of the shell, and a plurality of first sliders are fixed on the surface of the power mechanism. The first sliders slide on the surface of the first chute. A top caliper is fixed below the power mechanism. A groove body is opened in the inner cavity of the top caliper, and an action groove is opened on the lower side of the top caliper. The action groove slides on the surface of the brake disc body. Installation shells are fixed on both sides of the inner cavity of the floating caliper body, and a lifting mechanism is fixed in the inner cavity of the installation shell. A pressure sensor is fixed on one side of the lifting mechanism. The pressure sensor slides on the surface of the brake disc body.

[0008] The working principle of the present invention is as follows: The staff can use the lifting mechanism to drive the pressure sensor to move up and down. When the pressure sensor moves to a suitable position, the staff can make the braking part act on the surface of the pressure sensor, thereby measuring the acting force of the braking part, assisting the staff to judge whether the brake can be used safely. And when the staff issues a braking instruction to the brake, the power mechanism drives the top caliper to move, so that the action groove at the bottom of the top caliper fits the surface of the brake disc body, assisting the braking part of the brake. The staff can use the adjusting mechanism to finely adjust the floating caliper body up and down, so that the braking part of the brake acts on other positions on the surface of the brake disc body, enhancing the practicability of the brake.

[0009] The floating caliper body includes a first wear-resistant layer and a first lightweight layer. The first lightweight layer is arranged inside the floating caliper body, and the first wear-resistant layer wraps the first lightweight layer.

[0010] Adopting the above structure can prevent damage to the surface of the brake caused by friction and reduce the overall weight of the brake.

[0011] The material of the first wear-resistant layer is high manganese steel, and the material of the first lightweight layer is carbon fiber.

[0012] With the above structure, the impact resistance and friction resistance of the brake are enhanced, and carbon fiber is a lightweight material, which can reduce the weight of the brake.

[0013] The top clamp includes a second wear-resistant layer and a second lightweight layer. The second lightweight layer is arranged inside the top clamp, and the second wear-resistant layer wraps the surface of the second lightweight layer.

[0014] With the above structure, the wear resistance of the top clamp can be enhanced, and the weight is relatively low, which can reduce the overall weight.

[0015] The adjusting mechanism includes a motor. The motor is fixed in the inner cavity of the housing. A screw rod is fixed to the output shaft of the motor. A threaded sleeve is threadedly connected to the surface of the screw rod, and the other end of the threaded sleeve is fixed to the top of the floating caliper body.

[0016] With the above structure, the acting position of the floating caliper body on the brake disc body is changed.

[0017] Both sides of the bottom of the housing are fixed with telescopic rods, and the other side of the telescopic rods is fixed to the top of the floating caliper body.

[0018] With the above structure, the up and down adjustment of the floating caliper body is limited.

[0019] The power mechanism includes a first electric slider. The first electric slider is arranged in the inner cavity of the housing. A first sliding rod is slidably arranged in the inner cavity of the first electric slider. The first sliding rod is fixed to the top of the inner cavity of the housing. A plurality of connecting rods are annularly fixed to the bottom of the first electric slider, and the other ends of the connecting rods are fixed to the top of the top clamp.

[0020] With the above structure, part of the braking force during braking of the brake is shared, and the service life of the brake is enhanced.

[0021] A gasket is fixed to the bottom of the housing, and the connecting rod slides on the surface of the gasket.

[0022] With the above structure, the power mechanism is protected to prevent foreign objects or liquids from damaging the power mechanism.

[0023] The lifting mechanism includes a second electric slider. A second sliding rod slides in the inner cavity of the second electric slider. The top of the second sliding rod is fixed to the inner cavity of the mounting shell, and a pressure sensor is fixed to one side of the bottom of the second electric slider.

[0024] With the above structure, the magnitude of the braking force is measured to assist the staff in judging whether the brake can be used safely.

[0025] A second slider is fixed on the surface of the second electric slider, and a second sliding groove is formed in the inner cavity of the mounting shell, and the second slider slides on the surface of the second sliding groove.

[0026] With the above structure, the movement of the second electric slider is limited, and the stability of the second electric slider during movement can be enhanced.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. By setting the floating caliper body and the top caliper, the wear resistance of the surface of the brake is enhanced and the overall weight is relatively light. Before use, the staff can use the lifting mechanism to lift the pressure sensor so that the braking part acts on the surface of the pressure sensor, so as to achieve the purpose of self-inspection. During the use process, when the staff issues a braking instruction to the brake, under the action of the power mechanism, the top caliper moves towards the brake disc body, so that the action groove on the surface of the top caliper acts on the top of the brake disc body, thereby sharing the braking force when the brake is braking, so as to reduce the working burden of the braking part. And the staff can also use the adjusting mechanism to adjust the height of the brake, so that the position of the braking part changes, avoiding the distance between the braking part and the brake disc body becoming larger due to the braking part acting on the same place on the surface of the brake disc body for a long time, which may cause potential safety hazards. It solves the problem that the brake cannot be self-inspected before use, which reduces the practicability of the brake. At the same time, it also solves the problem that during the use of the brake, due to the braking part always acting on one place on the surface of the brake disc body, it is easy to cause poor braking effect. At the same time, it also solves the problems of single braking part and low service life of the braking part during the use of the brake.

[0029] 2. By limiting the materials of the first wear-resistant layer and the first lightweight layer, high manganese steel is a material that will quickly harden on the surface while the core still maintains extremely strong toughness under severe impact or contact stress. It is hard on the outside and tough on the inside, and can resist wear and impact. Using this material on the surface can enhance the impact resistance and friction resistance of the brake. And carbon fiber is a lightweight material that can reduce the weight of the brake.

[0030] 3. In the present invention, through the settings of the motor, screw rod, and threaded sleeve, during the use of this brake, if the same position of the brake disc body is continuously acted upon, the specific part of the brake disc body will become thinner, thereby reducing the service life of the brake disc body. When in use, the staff can turn on the motor. Under the action of the motor, the screw rod rotates and drives the threaded sleeve to move. Then, the floating caliper body fixedly connected to the threaded sleeve will move, thereby changing the acting position of the floating caliper body on the brake disc body, and thus increasing the service life of the brake disc body.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 - 10As shown in the figure, this lightweight and wear-resistant floating caliper disc brake includes a brake disc body 1 and a floating caliper body 2. The brake disc body 1 is movably arranged below the floating caliper body 2. Connectors 4 are fixed on both sides of the surface of the floating caliper body 2, and connection sliders 3 are fixed on the tops of the connectors 4. A housing 5 is arranged on the top of the floating caliper body 2, and an adjusting mechanism 6 is fixed in the inner cavity of the housing 5. A number of housings 8 are fixed on the top of the floating caliper body 2, and a power mechanism 9 is fixed in the inner cavity of the housing 8. A first chute 10 is opened in the inner cavity of the housing 8, and a number of first sliders 11 are fixed on the surface of the power mechanism 9. The first sliders 11 slide on the surface of the first chute 10. A top caliper 13 is fixed below the power mechanism 9. A groove 18 is opened in the inner cavity of the top caliper 13, and an acting groove 19 is opened on the lower side of the top caliper 13. The acting groove 19 slides on the surface of the brake disc body 1. Installation shells 14 are fixed on both sides of the inner cavity of the floating caliper body 2, and a lifting mechanism 15 is fixed in the inner cavity of the installation shell 14. A pressure sensor 16 is fixed on one side of the lifting mechanism 15. The pressure sensor 16 slides on the surface of the brake disc body 1. Through the settings of the floating caliper body 2 and the top caliper 13, the wear resistance of the surface of this brake is enhanced and the overall is relatively lightweight. And before use, the staff can use the lifting mechanism 15 to lift and lower the pressure sensor 16, so that the braking part acts on the surface of the pressure sensor 16, so as to achieve the purpose of self-checking. And during use, when the staff issues a braking instruction to this brake, under the action of the power mechanism 9, the top caliper 13 moves towards the brake disc body 1, so that the acting groove 19 on the surface of the top caliper 13 acts on the top of the brake disc body 1, so as to share the acting force during braking of this brake, so as to reduce the working burden of the braking part. And the staff can also use the adjusting mechanism 6 to adjust the height of this brake, so that the position of the braking part changes, avoiding the distance between the braking part and the brake disc body 1 becoming larger due to the braking part acting on the same place on the surface of the brake disc body 1 for a long time and generating potential safety hazards. It solves the problem that before the current brake is used, it cannot be self-checked and the practicability of the brake is reduced. At the same time, it also solves the problem that during the use of the brake, due to the braking part always acting on one place on the surface of the brake disc body 1, it is easy to cause poor braking effect. At the same time, it also solves the problems of single braking part and low service life of the braking part during the use of the brake.

[0044] The floating caliper body 2 includes a first wear-resistant layer 201 and a first lightweight layer 202. The first lightweight layer 202 is arranged inside the floating caliper body 2, and the first wear-resistant layer 201 wraps the first lightweight layer 202. In this embodiment, through the settings of the first wear-resistant layer 201 and the first lightweight layer 202, during the use or installation process of this brake, it is inevitable to rub against foreign objects. Under the protection of the first wear-resistant layer 201, it can prevent the surface of this brake from being damaged due to friction and affecting the appearance. And with the setting of the first lightweight layer 202, the overall weight of this brake can be reduced.

[0045] The material of the first wear-resistant layer 201 is high manganese steel, and the material of the first lightweight layer 202 is carbon fiber. In this embodiment, by defining the materials of the first wear-resistant layer 201 and the first lightweight layer 202, high manganese steel is a material that will rapidly harden on its surface while the core still maintains extremely strong toughness under severe impact or contact stress. It is hard on the outside and tough on the inside, resisting both wear and impact. Using this material on the surface can enhance the impact resistance and friction resistance of this brake, and carbon fiber is a lightweight material that can reduce the weight of this brake.

[0046] The top clamp 13 includes a second wear-resistant layer 1301 and a second lightweight layer 1302. The second lightweight layer 1302 is arranged inside the top clamp 13, and the second wear-resistant layer 1301 wraps the surface of the second lightweight layer 1302. In this embodiment, through the setting of the second wear-resistant layer 1301 and the second lightweight layer 1302, the wear resistance of the top clamp 13 can be enhanced, and the weight is relatively low, which can reduce the overall weight. Moreover, the materials of each layer of the top clamp 13 are the same as those of each layer of the floating clamp body 2.

[0047] The adjusting mechanism 6 includes a motor 601. The motor 601 is fixed in the inner cavity of the housing 5. A screw rod 602 is fixed to the output shaft of the motor 601. A threaded sleeve 603 is threadedly connected to the surface of the screw rod 602. The other end of the threaded sleeve 603 is fixed to the top of the floating clamp body 2. In this embodiment, through the setting of the motor 601, the screw rod 602, and the threaded sleeve 603, during the use of this brake, if it always acts on the same place of the brake disc body 1, it will make a specific place of the brake disc body 1 thinner, thereby reducing the service life of the brake disc body 1. When in use, the staff can turn on the motor 601. Under the action of the motor 601, the screw rod 602 rotates and drives the threaded sleeve 603 to move. Then, the floating clamp body 2 fixedly connected to the threaded sleeve 603 will move, thereby changing the acting position of the floating clamp body 2 on the brake disc body 1, and increasing the service life of the brake disc body 1.

[0048] Two sides of the bottom of the housing 5 are fixed with telescopic rods 7. The other side of the telescopic rods 7 is fixed to the top of the floating clamp body 2. In this embodiment, through the setting of the telescopic rods 7, when the floating clamp body 2 is adjusted up and down, it can limit the up and down adjustment of the floating clamp body 2 and increase the stability of the floating clamp body 2 during movement.

[0049] The power mechanism 9 includes a first electric slider 901. The first electric slider 901 is arranged in the inner cavity of the housing 8. A first slide bar 902 is slidably arranged in the inner cavity of the first electric slider 901. The first slide bar 902 is fixed to the top of the inner cavity of the housing 8. A plurality of connecting rods 903 are annularly fixed to the bottom of the first electric slider 901. The other ends of the connecting rods 903 are fixed to the top of the top clamp 13. In this embodiment, through the first electric slider 901, the first slide bar 902 and the connecting rods 903, when the staff issues a braking instruction to this brake, information will be transmitted to the first electric slider 901 at the same time. The first electric slider 901 will slide on the surface of the first slide bar 902 and drive the connecting rods 903 to move downward. And the top clamp 13 fixedly connected to the connecting rods 903 will also move downward, and the acting groove 19 on the surface of the top clamp 13 will act on the top of the floating caliper body 2. The braking effect is achieved through the frictional force between the floating caliper body 2 and the brake disc body 1, so as to share part of the braking force of this brake during braking and enhance the service life of this brake.

[0050] A sealing gasket 12 is fixed to the bottom of the housing 8. The connecting rods 903 slide on the surface of the sealing gasket 12. In this embodiment, through the setting of the sealing gasket 12, during the use of this brake, due to the high-speed rotation of the braked part, foreign objects or liquids will be splashed. Under the action of the sealing gasket 12, the power mechanism 9 is protected to prevent foreign objects or liquids from damaging the power mechanism 9.

[0051] The lifting mechanism 15 includes a second electric slider 1501. A second slide bar 1502 slides in the inner cavity of the second electric slider 1501. The top of the second slide bar 1502 is fixed to the inner cavity of the mounting shell 14. A pressure sensor 16 is fixed to one side of the bottom of the second electric slider 1501. In this embodiment, through the setting of the second electric slider 1501 and the second slide bar 1502, when this brake is in a non-working state, the staff can use the lifting mechanism 15 to drive the pressure sensor 16 to move. Under the action of the lifting mechanism 15, the pressure sensor 16 moves downward while fitting the surface of the brake disc body 1. Then the staff issues a braking instruction to this brake, so that the braking part acts on the surface of the pressure sensor 16, thereby measuring the magnitude of the braking force and assisting the staff in judging whether this brake can be used safely.

[0052] A second slider 17 is fixed to the surface of the second electric slider 1501. A second sliding groove 20 is formed in the inner cavity of the mounting shell 14. The second slider 17 slides on the surface of the second sliding groove 20. In this embodiment, through the setting of the second slider 17 and the second sliding groove 20, when the staff uses the second electric slider 1501 to slide, with the cooperation of the second slider 17 and the first sliding groove 10, the movement of the second electric slider 1501 can be limited, and the stability of the second electric slider 1501 during movement can be enhanced.

[0053] Working principle of the present invention: Before use, fix the housing 5 above the brake disc body 1, make the connecting slider 3 slide and connect to the surface of the object on the side of the brake disc body 1, and then the brake disc body 1 can be braked. During use, the staff can use the lifting mechanism 15. Under the action of the lifting mechanism 15, the pressure sensor 16 moves up and down. When the pressure sensor 16 moves to a suitable position, the staff can issue a braking command to this brake, so that the braking part acts on the surface of the pressure sensor 16, thereby measuring the acting force of the braking part, assisting the staff to judge whether this brake can be used safely. And when the staff issues a braking command to this brake, the power mechanism 9 will also start to work. Under the action of the first electric slider 901, the connecting rod 903 drives the top clamp 13 to move, so that the acting groove 19 at the bottom of the top clamp 13 fits the surface of the brake disc body 1, assisting the braking part of this brake, thereby enhancing the service life of this brake. During long-term braking, since this brake has been acting on the same position on the surface of the brake disc body 1, the service life of the brake disc body 1 will be reduced. The staff can use the adjusting mechanism 6. Under the action of the motor 601, the screw 602 rotates, and with the auxiliary action of the telescopic rod 7, the threaded sleeve 603 moves up and down, thereby finely adjusting the floating clamp body 2 up and down, making the braking part of this brake act on other positions on the surface of the brake disc body 1, enhancing the practicability of this brake.

[0054] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
