Description

Technical Field

[0001] This invention relates to the field of motorcycle parts technology, and specifically to a brake pump with an air-cooled heat dissipation system. Background Technology

[0002] As the core actuator of the braking system, the motorcycle brake pump's structural rationality and operational stability directly determine vehicle driving safety. Existing motorcycle brake pumps mainly adopt the hydraulic drive principle. Referring to the invention disclosure of patent number CN111878530A, entitled "A Novel Motorcycle Universal Brake Pump Body Structure", the existing brake pump's main structure includes: pump body, piston, brake pads, guide post, top plate, and hydraulic control components. The hydraulic control components include key components such as oil inlet, vent hole, oil chamber, and seals, forming a complete force transmission link to achieve the braking function. When the driver operates the brake lever, it drives the brake pump to compress hydraulic oil, which is then transported to the brake pump's oil chamber through the oil pipe. The hydraulic oil then enters the piston throughlet through the oil inlet, pushing the double pistons to move, thereby causing the two brake pads to clamp the brake disc in both directions.

[0003] Currently, motorcycle brake pumps on the market do not have active cooling mechanisms. They rely solely on the natural gap between the brake pads and brake discs, and the heat conduction of the pump body's metal material for passive cooling. This results in extremely low cooling efficiency. When drivers use the brakes frequently at high speeds or downhill, the friction between the brake pads and the high-speed rotating brake discs generates heat. This heat is then transferred through the piston, affecting the brake fluid temperature and potentially causing it to overheat or even boil. The passive cooling of existing brake pumps cannot quickly reduce the heat generated during braking. As a result, the brake pump is easily damaged, posing a safety hazard. Therefore, developing a compact and highly efficient motorcycle brake pump is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a brake pump with an air-cooled heat dissipation system, which aims to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a brake pump with an air-cooled heat dissipation system, comprising a pump body and a brake assembly;

[0006] The pump body has a brake channel in the middle for accommodating the brake disc, and hydraulic chambers are symmetrically arranged on both sides of the brake channel. The hydraulic chambers have oil inlet holes extending to the outside of the pump body, and the pump body has through holes on both sides communicating with the hydraulic chambers.

[0007] The brake assembly includes a brake plate and a push piston. The push piston is slidably disposed in the hydraulic chamber. The brake plate is disposed in the brake channel and fixedly connected to one end of the push piston. The other end of the push piston extends to the outside of the pump body through a through hole. An air inlet channel is provided through the push piston along the axial direction. The air inlet of the air inlet channel is located on the end face of the push piston extending to the outside of the pump body, and is used to guide external air in. Multiple air outlets are distributed in a ring on the end face of the push piston connected to the brake plate. The air outlets are connected to the air inlet channel, so that external air is blown to the back of the brake plate through the air inlet channel and blown out through the air outlets to form an active circulating cooling airflow for the brake plate.

[0008] Optionally, the push piston is a stepped cylindrical structure, which has a sliding section slidably connected to the hydraulic chamber, a guide section slidably connected to the through hole, and a planar portion disposed between the sliding section and the guide section. The air inlet channel passes through the guide section and the sliding section axially. The outer diameter of the guide section is smaller than the outer diameter of the sliding section. The outer side of the sliding section is tightly sealed against the inner wall of the hydraulic chamber, and the outer side of the guide section is tightly sealed against the inner side of the through hole.

[0009] Optionally, a first sealing ring is provided inside the hydraulic chamber to abut against the sliding section, and a second sealing ring is provided inside the through hole to abut against the guide section.

[0010] Optionally, the hydraulic chamber has an opening on the side facing the brake channel, and the through hole connects to the side of the hydraulic chamber away from the brake channel;

[0011] When the push piston is assembled in the hydraulic chamber, the flat part and the side wall of the hydraulic chamber away from the brake channel together form an oil injection space, and the oil inlet is connected to the oil injection space.

[0012] Optionally, the depth of the hydraulic chamber is greater than the stroke of the piston, the length of the guide section is greater than the depth of the hydraulic chamber, and the length of the sliding section is greater than or equal to the depth of the hydraulic chamber.

[0013] Optionally, at least two hydraulic chambers are provided on both sides of the pump body, the hydraulic chambers on the same side are interconnected by a connecting groove, and one of the hydraulic chambers is connected to the oil inlet.

[0014] Optionally, the connecting groove is inclined, with one end connected to the side of the hydraulic chamber with an oil inlet and close to the opening, and the other end inclined toward the back of another hydraulic chamber.

[0015] Optionally, the air inlet channel is connected to an air supply mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The brake pump with air cooling system provided by the present invention forms a directional air cooling system by setting an air inlet channel through the piston in the axial direction and setting an air outlet in a ring at one end connected to the brake plate. This system can quickly remove the heat generated by the brake plate during braking, effectively replacing the passive cooling method of the existing brake pump. It can effectively and quickly reduce the heat of the brake plate, reduce heat transfer, prevent the brake fluid from boiling due to high temperature, which could lead to loss of braking function or damage to the brake pump, and reduce safety hazards.

[0017] Meanwhile, the air-cooled heat dissipation system mainly relies on the piston design, without excessively altering the core braking layout of the pump body and brake components, achieving a synergistic effect of compact structure and efficient heat dissipation, and improving the operational stability of the braking system.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0029] like Figure 1-6 As shown, a brake pump with an air-cooled heat dissipation system includes a pump body 1, a brake assembly, and a brake disc. The pump body 1 has a brake channel 10 in the middle for accommodating the brake disc, with the brake disc located in the middle of the brake channel 10. Hydraulic chambers 101 are symmetrically arranged on both sides of the brake channel 10. Each hydraulic chamber 101 has an oil inlet hole 103 extending to the outside of the pump body 1. The oil inlets 103 on both sides can be connected by a conduit and connected to the brake pump through the conduit to realize synchronous oil injection or oil extraction from the two oil inlets 103. The pump body 1 has through holes 102 on both sides that communicate with the hydraulic chambers 101.

[0030] The brake assembly includes a brake plate 2 and a push piston 3. The push piston 3 is slidably disposed in the hydraulic chamber 101. The brake plate 2 is disposed in the brake channel 10 and fixedly connected to one end of the push piston 3. The brake plate 2 is located on both sides of the brake disc. By pushing the push piston 3 to slide towards the center, the brake plate 2 is pushed close to the brake disc to achieve braking.

[0031] The brake plate 2 is disposed within the brake channel 10 and fixedly connected to one end of the push piston 3. The other end of the push piston 3 extends to the outside of the pump body 1 through the through hole 102. The push piston 3 is provided with an air inlet channel 30 through it along the axial direction. The air inlet of the air inlet channel 30 is located on the end face of the push piston 3 extending to the outside of the pump body 1, and is used to guide external air in. The push piston 3 is connected to one end face of the brake plate 2 and has a plurality of air outlets 300 distributed in a ring. The air outlets 300 are connected to the air inlet channel 30, so that external air is blown to the back of the brake plate 2 through the air inlet channel 30 and blown out through the air outlets 300, thereby forming an active circulating cooling airflow for the brake plate 2.

[0032] The brake pump with a wind-cooled heat dissipation system provided by this invention forms a directional wind-cooled heat dissipation system by axially providing an air inlet channel 30 through the piston 3 and an air outlet 300 annularly provided at the end connecting to the brake plate 2. This system can quickly remove the heat generated by the brake plate 2 during braking, effectively replacing the passive heat dissipation method of existing brake pumps. It can effectively and quickly reduce the heat of the brake plate 2 and reduce the heat transfer to the piston 3. (See reference...) Figure 1-3 Air enters through the air intake channel 30 and blows onto the brake pad 2. Its heat dissipation path is opposite to the heat transmission path of the brake pad 2, which greatly reduces the heat transfer to the push piston 3, thereby preventing the brake fluid temperature in the hydraulic chamber 101 from becoming too high and preventing brake fluid boiling due to high temperature, which could lead to loss of braking function or damage to the brake pump, thus reducing safety hazards. Moreover, the air outlets 300 are distributed in a ring on one end face of the push piston 3. The air outlets 300 are perpendicular to the air intake channel 30. After entering from one end of the air intake channel 30, the air blows directly onto the back of the brake pad 2 and then blows out from each air outlet 300. This allows the air to reach the core heat-generating area of ​​the brake pad 2 covered by the push piston 3 through the air intake channel 30, and then diffuse outward through the ring-shaped air outlets 300 to carry away the heat in that area. At the same time, the air can also carry away the heat from other surrounding areas of the brake pad 2.

[0033] Meanwhile, the air-cooled heat dissipation system mainly relies on the design of the piston 3, without excessively modifying the core braking layout of the pump body 1 and the brake assembly, achieving a synergistic effect of compact structure and efficient heat dissipation, and improving the operational stability of the braking system.

[0034] In some embodiments, the piston 3 is a stepped cylindrical structure, having a sliding section 301 slidably connected to the hydraulic chamber 101, a guide section 302 slidably connected to the through hole 102, and a planar portion 303 disposed between the sliding section 301 and the guide section 302. The air inlet channel 30 extends axially through the guide section 302 and the sliding section 301. The guide section 302 and the sliding section 301 are both located on the same central axis, and the outer diameter of the guide section 302 is smaller than the outer diameter of the sliding section 301. Correspondingly, the inner diameter of the through hole 102 is smaller than the inner diameter of the hydraulic chamber 101. The outer side of the sliding section 301 is tightly sealed against the inner wall of the hydraulic chamber 101, and the outer side of the guide section 302 is tightly sealed against the inner side of the through hole 102. The through hole 102 and the guide section 302 can assist in pushing the piston. The piston 3 is positioned to ensure that the piston 3 can slide linearly. Specifically, a first sealing ring 111 is provided on the inner side of the hydraulic chamber 101 to abut against the sliding section 301, and a second sealing ring 112 is provided on the inner side of the through hole 102 to abut against the guide section 302. This is mainly to prevent hydraulic oil leakage. The inner walls of the hydraulic chamber 101 and the through hole 102 are provided with grooves. The first sealing ring 111 and the second sealing ring 112 are fixed in the grooves and protrude from the grooves. The protruding parts abut against the sliding section 301 and the guide section 302. The first sealing ring 111 and the second sealing ring 112 can be made of rubber rings, silicone rubber, polyurethane, etc. In addition, at least one of the first sealing ring 111 and the second sealing ring 112 is provided, and the specific number can be determined according to actual needs.

[0035] In some embodiments, the hydraulic chamber 101 has an opening (not shown in the figure) on the side facing the brake channel 10. This opening is mainly used for the piston 3 to extend out of the hydraulic chamber 101 and connect to the brake plate 2. The through hole 102 is connected to the side of the hydraulic chamber 101 away from the brake channel 10. The guide section 302 is used to seal the hydraulic chamber 101 and the through hole 102, and the sliding section 301 is used to seal the side of the hydraulic chamber 101 near the opening. The oil inlet 103 is disposed between the second sealing ring 112 and the first sealing ring 111. When the piston 3 is assembled in the hydraulic chamber 101, the flat part 303 and the side wall of the hydraulic chamber 101 away from the brake channel 10 together form an oil injection space 110. The oil inlet 103 is connected to the oil injection space 110. The piston 3 is extended or reset as hydraulic oil is injected or withdrawn.

[0036] The depth of the hydraulic chamber 101 is greater than the stroke of the piston 3, the length of the guide section 302 is greater than the depth of the hydraulic chamber 101, and the length of the sliding section 301 is greater than or equal to the depth of the hydraulic chamber 101. The sliding section 301 is not completely close to the back of the hydraulic chamber 101, and a certain amount of oil filling space 110 needs to be reserved. Therefore, the sliding section 301 is located inside the hydraulic chamber 101, and one end extends out of the hydraulic chamber 101 through an opening to prevent the guide section 302 from detaching from the through hole 102 or the sliding section 301 from detaching from the hydraulic chamber 101 when the piston 3 slides, thereby ensuring that the hydraulic oil is in the oil filling space 110 and will not leak.

[0037] In some embodiments, at least two hydraulic chambers 101 are provided on both sides of the pump body 1. The hydraulic chambers 101 on the same side are interconnected through a connecting groove 104, and one of the hydraulic chambers 101 is connected to the oil inlet hole 103. If two hydraulic chambers 101 are provided on one side of the pump body 1, that is, a total of four hydraulic chambers 101 are provided. Then, the corresponding through hole 102 and push piston 3 are also provided as four. Each hydraulic chamber 101 is provided with a push piston 3. The two push pistons 3 on the same side are connected together and push the brake plate 2 on that side, so that the brake plate 2 moves more quickly and powerfully. The connecting groove 104 is inclined, with one end connected to the side of the hydraulic chamber 101 with the oil inlet hole 103 and close to the opening, and this end corresponding to the oil inlet hole 103. The other end is inclined toward the back of the other hydraulic chamber 101, ensuring that the two hydraulic chambers 101 on the same side receive oil evenly. When the brake pump is installed and the oil filling hole is facing upward, the inclined connecting groove 104 allows hydraulic oil to enter one of its hydraulic chambers 101 from the oil inlet hole 103. As the hydraulic oil fills the lower part of the hydraulic chamber 101, when the hydraulic oil exceeds half of the lower part of the oil filling space 110, the hydraulic oil flows naturally along the horizontally inclined path to the side wall of the other hydraulic chamber 101. This avoids the filling lag caused by the oil only flowing at the same height plane when the horizontal straight hole is connected, thereby achieving synchronous and balanced pressure in the two chambers.

[0038] To ensure sufficient airflow into the air intake duct 30 and to prevent it from being affected by road conditions, the air intake duct 30 is connected to an air supply mechanism (not shown in the figure). The air supply mechanism introduces cold air into the air intake duct 30 for heat dissipation of the brake plate 2. The air supply mechanism can be an existing blower, miniature blower, etc.
