Description

Technical Field

[0001] This utility model relates to the field of brake caliper technology, and in particular to a novel brake caliper pump body. Background Technology

[0002] Brake calipers are used to clamp the brake disc when a car is braking, thereby achieving braking. Currently, the brake caliper assembly on a car consists of a caliper body, a caliper bracket, an inner friction pad, and an outer friction pad. The caliper body contains a wheel cylinder, which is adjacent to the inner friction pad. The edge of the brake disc is inserted into the jaws formed between the inner and outer friction pads. When the car brakes, pressurized fluid pushes the wheel cylinder to move, and then the wheel cylinder pushes the inner friction pad towards the outer friction pad, reducing the size of the jaws and thus clamping the brake disc to achieve braking.

[0003] Existing brake caliper friction pads generally cool down by transferring heat to the brake disc, while the friction pads themselves only dissipate heat through air duct design. They carry away the heat generated during braking through the air duct, but the heat dissipation effect is poor, which will affect the performance of the brake pads, leading to an increase in braking distance and increasing the risk of vehicle driving.

[0004] Therefore, there is an urgent need to provide a new type of brake caliper pump body to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of brake caliper pump body.

[0006] To solve the above-mentioned technical problems, the present invention provides a novel brake caliper pump body, including a brake caliper body, wherein oil inlet pipes are fixedly installed on both sides of the brake caliper body, and oil pipe connectors are fixedly installed on one side of each of the two oil inlet pipes. The brake caliper body is provided with a disassembly and assembly mechanism, the oil inlet pipes are provided with a circulation mechanism, and the disassembly and assembly mechanism is provided with a leak-proof mechanism.

[0007] The present invention is further configured such that: the disassembly and assembly mechanism includes a piston sealed and installed inside the oil inlet pipe, one end of the piston is fixedly mounted with an mounting plate, and the bottom of the mounting plate is tightly fitted with a friction plate.

[0008] Through the above technical solution, hydraulic oil flows into the brake caliper body through the oil inlet pipe. The hydraulic pressure acts on the piston, causing the piston to move outward, pushing the mounting plate and friction pads to clamp the rotating brake disc, generating friction.

[0009] The present invention is further configured such that: a bolt with one end penetrating through and extending to the outside of the mounting plate is fixedly installed at the top of the friction plate, and a nut is threaded on the outer surface of the bolt.

[0010] With the above technical solution, the friction plate is connected to the mounting plate by bolts, and the connected friction plate and mounting plate are fixed by nuts.

[0011] The present invention is further configured such that: the circulation mechanism includes a circulation pump fixed to the inner wall of the oil inlet pipe, and a circulation double sleeve that penetrates through and extends to the outside of the oil inlet pipe is fixedly installed at one end of the circulation pump, and the circulation double sleeve is connected to the cooling equipment through an interface.

[0012] Through the above technical solution, the cooling equipment, together with the circulating pump, replaces the cooling oil through a double-sleeve circulating system.

[0013] The present invention is further configured such that: a cooling inlet pipe with one end penetrating through and extending into the piston is fixedly installed at the other end of the circulating pump, and a cooling outlet pipe with one end penetrating through and extending into the piston is fixedly installed on both sides of the circulating pump; the outer surfaces of the cooling inlet pipe and the cooling outlet pipe are sealed to the inside of the piston by rubber rings.

[0014] With the above technical solution, cooling oil enters through the inner pipe of the double-walled circulation system and the cooling inlet pipe, and is discharged through the cooling outlet pipe and the outer pipe of the double-walled circulation system.

[0015] The present invention is further configured such that: the leak-proof mechanism includes a fixed plate fixed to the inner wall of the piston, a slide bar plate is slidably installed inside the fixed plate through an annular frame, a columnar spring is fixedly installed between the slide bar plate and the slide bar plate, and a rubber sealing plate is fixedly installed at the other end of the slide bar plate.

[0016] Through the above technical solution, the cylindrical spring drives the slide plate and the rubber sealing plate to seal the top of the fixed plate.

[0017] The present invention is further configured such that: a connecting pipe with one end penetrating through and extending to the outside is fixedly installed inside the friction plate, and a sliding rod top plate is fixedly installed inside the connecting pipe by a ring frame.

[0018] Through the above technical solution, the friction plate is connected to the piston through the connecting pipe, and the top plate of the slide rod drives the slide plate to squeeze the cylindrical spring, so that the top of the fixed plate is no longer sealed.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model, by providing a disassembly and assembly mechanism and a circulation mechanism, can cool the friction pads with coolant, improve the cooling effect of the friction pads, effectively avoid the performance degradation of the friction pads caused by high temperature, extend the service life of the friction pads, ensure the reliability of the braking system, and at the same time realize the quick disassembly and assembly of the friction pads, reduce the skill requirements of technicians, and ensure that the maintenance of the braking system is more convenient.

[0021] 2. This utility model, by incorporating a leak-proof mechanism, prevents coolant from flowing out of the mounting plate opening, ensuring the recycling of coolant, which not only reduces resource waste but also maintains the cleanliness and stable operation of the braking system.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figures 1-5A novel brake caliper pump body includes a brake caliper body 1. Oil inlet pipes 2 are fixedly installed on both sides of the brake caliper body 1. Oil pipe connectors 3 are fixedly installed on one side of each of the two oil inlet pipes 2. An assembly / disassembly mechanism 4 is provided inside the brake caliper body 1. The assembly / disassembly mechanism 4 includes a piston 401 sealed inside the oil inlet pipes 2. An mounting plate 402 is fixedly installed at one end of the piston 401. A friction plate 403 is tightly fitted to the bottom of the mounting plate 402. A bolt 404, with one end penetrating and extending to the outside of the mounting plate 402, is fixedly installed at the top of the friction plate 403. A nut 405 is threaded onto the outer surface of the bolt 404. Hydraulic oil flows into the brake caliper body 1 through the oil inlet pipes 2. The hydraulic pressure acts on the piston 401, causing the piston 401 to move outward, pushing the mounting plate 402 and the friction plate 403 to clamp the rotating brake disc, generating friction. The friction plate 403 is connected to the mounting plate 402 by the bolt 404, and the nut 405 secures the connected friction plate 403 and mounting plate 402.

[0030] like Figures 2-4 As shown, a circulation mechanism 5 is provided inside the oil inlet pipe 2. The circulation mechanism 5 includes a circulation pump 501 fixed to the inner wall of the oil inlet pipe 2. One end of the circulation pump 501 is fixedly installed with a circulation double sleeve 502 that penetrates through and extends to the outside of the oil inlet pipe 2. The circulation double sleeve 502 is connected to the cooling equipment through an interface. The other end of the circulation pump 501 is fixedly installed with a cooling inlet pipe 503 that penetrates through and extends into the piston 401. Both sides of the circulation pump 501 are fixedly installed with a cooling outlet pipe that penetrates through and extends into the piston 401. 504. The outer surfaces of the cooling inlet pipe 503 and the cooling outlet pipe 504 are sealed to the inside of the piston 401 by rubber rings 505. The cooling equipment, together with the circulating pump 501, drives the cooling oil to flow through the circulating double sleeve pipe 502, so that the cooling oil enters through the inner pipe of the circulating double sleeve pipe 502 and the cooling inlet pipe 503, and is discharged through the cooling outlet pipe 504 and the outer pipe of the circulating double sleeve pipe 502. The rubber ring 505 ensures that the movement of the piston 401 will not affect the connection between the cooling inlet pipe 503 and the cooling outlet pipe 504.

[0031] like Figure 4 and Figure 5As shown, the disassembly and assembly mechanism 4 is equipped with a leak-proof mechanism 6. The leak-proof mechanism 6 includes a fixed plate 601 fixed to the inner wall of the piston 401. A slide bar plate 602 is slidably installed inside the fixed plate 601 through an annular frame. A columnar spring 603 is fixedly installed between the slide bar plates 602. A rubber sealing plate 604 is fixedly installed at the other end of the slide bar plate 602. A connecting pipe 605 with one end penetrating and extending to the outside is fixedly installed inside the friction plate 403. A slide bar top plate 606 is fixedly installed inside the connecting pipe 605 through an annular frame. The columnar spring 603 drives the slide bar plate 602 and the rubber sealing plate 604 to seal the top of the fixed plate 601 to prevent the cooling oil from continuing to flow out after the friction plate 403 is removed. The friction plate 403 is connected to the piston 401 through the connecting pipe 605. The slide bar top plate 606 drives the slide bar plate 602 to squeeze the columnar spring 603, so that the top of the fixed plate 601 is no longer sealed.

[0032] In use, hydraulic oil flows into the brake caliper body 1 through the inlet pipe 2. The hydraulic pressure acts on the piston 401, causing it to move outward. The rubber ring 505 ensures that the movement of the piston 401 does not affect the connection between the cooling inlet pipe 503 and the cooling outlet pipe 504. This pushes the mounting plate 402 and the friction plate 403 to clamp the rotating brake disc, generating friction. The cooling equipment, in conjunction with the circulation pump 501, drives the cooling oil to flow through the double-sleeve circulation pipe 502. The cooling oil enters the friction plate 403 through the inner pipe of the double-sleeve circulation pipe 502 and the cooling inlet pipe 503. Then, the cooling oil is discharged into the cooling system through the cooling outlet pipe 504 and the outer pipe of the double-sleeve circulation pipe 502. When replacing the friction plate 403, the friction plate 403 is removed using the nut 405. The cylindrical spring 603 drives the slide plate 602 and the rubber sealing plate 604 to seal the top of the fixing plate 601, preventing the cooling oil from continuing to flow out after the friction plate 403 is removed. The new friction plate 403 is connected to the mounting plate 402 using bolts 404, and the new friction plate 403 and the mounting plate 402 are fixed using the nut 405. The friction plate 403 is connected to the piston 401 through the connecting pipe 605. The slide plate 606 drives the slide plate 602 to compress the cylindrical spring 603, so that the top of the fixing plate 601 is no longer sealed, facilitating the flow of cooling oil.
