Description

Technical Field

[0001] This invention relates to the field of disc brake structure technology, specifically a disc brake structure with heat dissipation function. Background Technology

[0002] The braking systems used in automobiles are mainly disc brakes. When braking, the high temperature generated by the friction between the brake pads and the brake disc often reduces the braking effect of the disc brake itself. Common heat dissipation methods try to maximize the heat dissipation of the brake disc, but they are limited to natural heat dissipation through the contact between the brake disc and the air. This kind of heat dissipation is too passive and has low heat dissipation efficiency. At the same time, it ignores the heat dissipation of the brake pads. During the long-term braking during the driving process, the brake pad temperature will become too high, affecting the service life of the brake pads and the braking effect. To this end, we have introduced a disc brake structure with heat dissipation function. Summary of the Invention

[0003] The purpose of this invention is to provide a disc brake structure with heat dissipation function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A disc brake structure with heat dissipation function includes a disc brake disc, a transmission mechanism and a brake assembly. The disc brake disc includes a left disc mechanism and a right disc mechanism fixedly installed on the left and right sides, and a sealing seat fixed between the left disc mechanism and the right disc mechanism, which is used to seal the cavity formed between the left disc mechanism and the right disc mechanism.

[0006] The left-side disc mechanism includes a left brake disc and a first connecting cylinder located at the middle of the left end of the left brake disc; the right-side disc mechanism includes a right brake disc and a second connecting cylinder located at the middle of the right end of the right brake disc.

[0007] The transmission mechanism includes a transmission shaft tube and a transmission shaft inside the transmission shaft tube. The first connecting sleeve is sleeved on the outside of the transmission shaft tube, and the second connecting sleeve is sleeved on the outside of the transmission shaft. The gear in the middle of the right end of the transmission shaft is inserted and fixed to the gear insertion hole in the middle of the second connecting sleeve.

[0008] Fan blades are fixed on the drive shaft and rotate under the drive of the drive shaft to introduce air into the cavity through the inside of the drive shaft tube. Several sets of baffles are evenly distributed on the middle of the right end surface of the left brake disc and the middle of the left end surface of the right brake disc. They are used to turbulent the air in the cavity so that the air in the cavity diffuses out through the heat dissipation channel structure on the disc brake disc to dissipate heat from the disc brake disc.

[0009] The brake assembly covers the outside of the disc brake disc, and the brake pads inside the brake assembly are provided with ventilation channels. When the brake pads are in close contact with the disc brake disc, some of the air diffused out through the heat dissipation channel structure flows in through the top of the ventilation channel and then flows out from the bottom of the ventilation channel, thereby achieving heat dissipation of the brake pads.

[0010] Preferably, the left brake disc has a left limiting ring integrally formed therewith at its right end, and the right brake disc has a right limiting ring integrally formed therewith at its left end. The sealing seat is a sealing ring, which is sleeved on the outside between the left limiting ring and the right limiting ring.

[0011] The sealing ring has sealing rings on both sides that fit against the right end surface of the left brake disc and the left end surface of the right brake disc, respectively. Several sets of fastening screws on the left brake disc pass through the sealing ring and are screwed onto the right brake disc.

[0012] Preferably, the left limiting ring and the right limiting ring are respectively provided with a first positioning groove and a second positioning groove symmetrically distributed vertically, and the inner sidewall of the sealing ring is provided with two sets of positioning blocks, which are locked in the corresponding first positioning groove and second positioning groove. The left end surface of the right limiting ring is evenly distributed with several sets of positioning posts, which are inserted into the corresponding positioning holes on the left limiting ring.

[0013] Preferably, the heat dissipation channel structure includes several sets of heat dissipation grooves evenly distributed on the surfaces of the left and right brake discs, several sets of first heat dissipation holes evenly distributed on the outer sidewall surfaces of the left and right brake discs, and several sets of second heat dissipation holes evenly distributed on the surface of the second connecting cylinder.

[0014] The spoiler is located between two adjacent sets of heat dissipation channels. The heat dissipation channels are connected to the corresponding first heat dissipation holes through the channels inside the left and right brake discs. A guide arc groove is provided at the connection between the channel and the first heat dissipation hole. The guide arc groove is used to allow the air flowing out through the first heat dissipation hole to flow into the ventilation duct through the top and then out from the bottom of the ventilation duct.

[0015] Preferably, a first bearing is sleeved on the outside of the transmission shaft tube, the first bearing is embedded inside the first connecting cylinder, and a protective ring is provided on the inner side of the left end of the first connecting cylinder to prevent the first bearing from slipping off through the left end of the first connecting cylinder.

[0016] A second bearing located on the left side of the fan blade is sleeved on the drive shaft, and the second bearing is embedded inside the drive shaft tube.

[0017] An air inlet pipe is connected to the drive shaft tube, which is used to introduce air into the right end of the drive shaft tube. The air is then introduced into the cavity through the air nozzle connected to the right end of the drive shaft tube under the action of the fan blade rotation.

[0018] The right end of the first connecting cylinder is provided with an annular groove, the inner diameter of the left and right ends of the annular groove increases sequentially, and the air outlet of the air nozzle is aligned with the middle of the annular groove.

[0019] The second connecting cylinder has a third bearing embedded inside, which is sleeved on the outside of the drive shaft.

[0020] Preferably, the brake assembly includes a brake seat covering the outside of the disc brake disc, with a mounting seat at its left end, a connecting plate fixed on the drive shaft tube, and the mounting seat fixed to the right end of the connecting plate by screws;

[0021] The brake pads are provided in two symmetrical sets, and they are driven to move horizontally left and right by hydraulic cylinders fixed at both ends of the brake seat.

[0022] The brake pad has an inverted V-shaped opening at the top, and its bottom is connected to the top of the ventilation duct.

[0023] Compared with the prior art, the beneficial effects of the present invention are: as the car moves, the fan blades fixed on the drive shaft rotate, which is used to quickly introduce air into the cavity through the inside of the drive shaft tube, and the air in the cavity is quickly discharged through the heat dissipation groove, the second heat dissipation hole and the first heat dissipation hole, thereby achieving rapid heat dissipation of the left and right disc mechanisms.

[0024] Several sets of spoilers are evenly distributed on the middle of the right end surface of the left brake disc and the middle of the left end surface of the right brake disc. These spoilers are used to turbulent the air in the cavity, so that the air that just entered the cavity can quickly diffuse in the cavity and mix with the original air in the cavity, thereby quickly absorbing the heat in the cavity and dissipating heat from the disc brake disc.

[0025] The brake pads have ventilation channels inside. When the brake pads are in close contact with the disc brake disc, the air that diffuses out through the first heat dissipation hole flows into the ventilation channel from the top and out from the bottom, thereby achieving heat dissipation for the brake pads.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-9 The present invention provides a technical solution:

[0038] Example 1:

[0039] A disc brake structure with heat dissipation function includes a disc brake disc, a transmission mechanism 5 and a brake assembly 4. The disc brake disc includes a left disc mechanism 6 and a right disc mechanism 3 fixedly installed on the left and right sides, and a sealing seat 2 fixed between the left disc mechanism 6 and the right disc mechanism 3, which is used to seal the cavity formed between the left disc mechanism 6 and the right disc mechanism 3.

[0040] The left-side disc mechanism 6 includes a left brake disc 61 and a first connecting cylinder 62 located at the middle of the left end of the left brake disc 61; the right-side disc mechanism 3 includes a right brake disc 31 and a second connecting cylinder 32 located at the middle of the right end of the right brake disc 31.

[0041] The transmission mechanism 5 includes a transmission shaft tube 56 fixed on the vehicle chassis and a transmission shaft 51 inside the transmission shaft tube 56. The first connecting cylinder 62 is sleeved on the outside of the transmission shaft tube 56, and the second connecting cylinder 32 is sleeved on the outside of the transmission shaft 51. The gear 52 at the middle of the right end of the transmission shaft 51 is inserted and fixed to the gear insertion hole 321 in the middle of the second connecting cylinder 32.

[0042] A fan blade 57 is fixed on the drive shaft 51 and rotates under the drive of the drive shaft 51. It is used to introduce air into the cavity through the inside of the drive shaft tube 56. Several sets of baffles 8 are evenly distributed on the middle of the right end surface of the left brake disc 61 and the middle of the left end surface of the right brake disc 31. They are used to turbulent the air in the cavity, so that the air in the cavity diffuses out through the heat dissipation channel structure on the disc brake disc, thereby dissipating heat from the disc brake disc.

[0043] The brake assembly 4 covers the outside of the disc brake disc. The brake pad 45 inside the brake assembly 4 is provided with a ventilation channel 47. When the brake pad 45 is in close contact with the disc brake disc, part of the air diffused out through the heat dissipation channel structure flows into the top of the ventilation channel 47 and then flows out from the bottom of the ventilation channel 47, thereby achieving heat dissipation of the brake pad 45.

[0044] Example 2:

[0045] In this embodiment, such as Figure 2-4 As shown, the left brake disc 61 has a left limiting ring 63 integrally formed with it at the right end, and the right brake disc 31 has a right limiting ring 33 integrally formed with it at the left end. The sealing seat 2 is a sealing ring 21, which is sleeved on the outside between the left limiting ring 63 and the right limiting ring 33.

[0046] The sealing ring 21 has sealing rings 22 on both sides that fit against the right end surface of the left brake disc 61 and the left end surface of the right brake disc 31, respectively. Several sets of fastening screws 64 on the left brake disc 61 pass through the sealing ring 21 and are screwed onto the right brake disc 31.

[0047] The left limiting ring 63 and the right limiting ring 33 are respectively provided with a first positioning groove 631 and a second positioning groove 331 symmetrically distributed vertically, and the inner sidewall of the sealing ring 21 is provided with two sets of positioning blocks 23, which are locked in the corresponding first positioning groove 631 and second positioning groove 331. The left end surface of the right limiting ring 33 is evenly distributed with several sets of positioning posts 332, and the positioning posts 332 are inserted into the corresponding positioning holes 632 on the left limiting ring 63.

[0048] This allows for quick and accurate alignment of the left brake disc 61 and right brake disc 31 during assembly, ensuring a secure installation after the fastening screws 64 are tightened. Simultaneously, when the brake pads 45 contact and rub against the left and right brake discs 61 and 31, it ensures that the left and right brake discs 61 and 31 rotate together without any rotational deviation.

[0049] Although rainwater can enter the cavities inside the left brake disc 61 and right brake disc 31 through the heat dissipation channel 7, the sealing ring 21 can seal the cavities inside the left brake disc 61 and right brake disc 31, thus preventing most rainwater from entering the cavities through the gap between the left brake disc 61 and right brake disc 31. Compared to an open design between the left brake disc 61 and right brake disc 31, this can prevent a large amount of rainwater from entering, which is especially effective when the car is stopped.

[0050] Even if a small amount of rainwater enters the cavity inside the left brake disc 61 and the right brake disc 31, the heat generated by the contact friction between the brake pad 45 and the left brake disc 61 and the right brake disc 31 will evaporate the small amount of rainwater in the cavity, and will not cause corrosion on the inner wall of the brake pad 45 and the left brake disc 61 and the right brake disc 31 during long-term use.

[0051] Furthermore, the small amount of rainwater entering the cavity also helps to absorb the heat from the left brake disc 61 and the right brake disc 31, thus playing a role in heat dissipation.

[0052] Example 3:

[0053] In this embodiment, such as Figure 2 , 3 As shown in Figure 7, the heat dissipation channel structure includes several sets of heat dissipation grooves 7 evenly distributed on the surfaces of the left brake disc 61 and the right brake disc 31, several sets of first heat dissipation holes 71 evenly distributed on the outer sidewall surfaces of the left brake disc 61 and the right brake disc 31, and several sets of second heat dissipation holes 323 evenly distributed on the surface of the second connecting cylinder 32.

[0054] The right end of the second connecting cylinder 32 is provided with several sets of bolts 322. These are used to fix the car wheels.

[0055] The spoiler 8 is located between two adjacent sets of heat dissipation channels 7. The heat dissipation channels 7 are connected to the corresponding first heat dissipation holes 71 through the channels 72 inside the left brake disc 61 and the right brake disc 31. A guide arc groove 73 is provided at the connection between the channel 72 and the first heat dissipation hole 71. The guide arc groove 73 is used to allow the air flowing out through the first heat dissipation hole 71 to flow into the top of the ventilation channel 47 and then flow out from the bottom of the ventilation channel 47.

[0056] Example 4:

[0057] In this embodiment, such as Figure 9 As shown, a first bearing 1 is sleeved on the outside of the transmission shaft tube 56. The first bearing 1 is embedded inside the first connecting cylinder 62, and a protective ring 622 is provided on the inner side of the left end of the first connecting cylinder 62 to prevent the first bearing 1 from slipping off through the left end of the first connecting cylinder 62.

[0058] A second bearing 58 located on the left side of the fan blade 57 is sleeved on the drive shaft 51, and the second bearing 58 is embedded inside the drive shaft tube 56.

[0059] An air inlet pipe 55 is connected to the drive shaft tube 56, which is used to introduce air into the right end of the drive shaft tube 56, so that the air is introduced into the cavity through the air nozzle 54 connected to the right end of the drive shaft tube 56 under the action of the fan blade 57 rotation.

[0060] The other end of the intake pipe 55 can be connected to an air pump or to an air collection horn box inside the air intake grille at the front of the car.

[0061] The air pump operates, introducing air through the air inlet pipe 55 into the inside of the right end of the drive shaft pipe 56;

[0062] As the car moves forward, air enters the air intake horn box, and then the air inside the air intake horn box is introduced into the right end of the drive shaft tube 56 through the intake pipe 55.

[0063] The first connecting cylinder 62 has an annular groove 621 at its right end, and the air outlet of the air nozzle 54 is aligned with the middle of the annular groove 621. After the air is discharged through the air outlet of the air nozzle 54, it blows towards the annular groove 621. Since the inner diameter of the left and right ends of the annular groove 621 increases sequentially, the air can quickly diffuse into the cavity when it passes through the right end of the annular groove 621.

[0064] The second connecting cylinder 32 has a third bearing 324 embedded inside, which is sleeved on the outside of the drive shaft 51.

[0065] The brake assembly 4 includes a brake seat 41 covering the outside of the disc brake disc, a mounting seat 42 at its left end, a connecting plate 53 fixed on the drive shaft tube 56, and the mounting seat 42 fixed to the right end of the connecting plate 53 by screws 43.

[0066] Example 5:

[0067] In this embodiment, such as Figure 6-7 As shown in Figure 9, the brake pads 45 are provided in two symmetrical sets, and they are driven to move horizontally left and right by hydraulic cylinders 44 fixed at both ends of the brake seat 41. When the hydraulic cylinders 44 drive the brake pads 45 to press against the outer end surfaces of the left brake disc 61 and the right brake disc 31, friction is formed on the left brake disc 61 and the right brake disc 31 to achieve braking operation. At this time, the friction causes the left brake disc 61 and the right brake disc 31 to generate high temperature. Most of the temperature will dissipate when the left brake disc 61 and the right brake disc 31 come into contact with the air in the atmosphere, but some heat will still not dissipate in time and thus accumulate in the cavity between the left brake disc 61 and the right brake disc 31.

[0068] The brake pad 45 has an inverted V-shaped opening 46 at its top, and its bottom is connected to the top of the ventilation duct 47. Air flowing out through the first heat dissipation hole 71 blows toward the inverted V-shaped opening 46 at the top of the brake pad 45. The inverted V-shaped opening 46 allows the air blowing toward the top of the brake pad 45 to quickly enter the ventilation duct 47.

[0069] Specifically, in use, when the car moves forward or backward, the car engine drives the drive shaft 51, causing the disc brake disc composed of the fan blade 57, the left disc mechanism 6 and the right disc mechanism 3, as well as the car wheels, to rotate.

[0070] As the fan blade 57 rotates, the air inside the right end of the drive shaft tube 56 is introduced into the cavity through the air nozzle 54 connected to the right end of the drive shaft tube 56.

[0071] The rotation of the left disk mechanism 6 and the right disk mechanism 3 drives the spoiler 8 to rotate, which in turn causes the spoiler 8 to disturb the air in the cavity, so that the air that just entered the cavity can quickly diffuse in the cavity and mix with the original air in the cavity, thereby achieving rapid absorption of heat in the cavity.

[0072] Subsequently, a portion of the air in the cavity will enter the first heat dissipation hole 71 through the channel 72, thereby allowing the air in the cavity to be discharged through the heat dissipation channel 7, the second heat dissipation hole 323 and the first heat dissipation hole 71 respectively, and at the same time dissipating the heat in the cavity, forming heat dissipation for the left side disk mechanism 6 and the right side disk mechanism 3.

[0073] When a portion of the air in the cavity enters the first heat dissipation hole 71 through the channel 72, the air flowing out of the first heat dissipation hole 71 is blown toward the top of the brake pad 45 by the setting of the guide arc groove 73, and mixes with the air in the atmosphere. It then flows in through the top of the ventilation channel 47 and flows out from the bottom of the ventilation channel 47, thereby carrying away the heat generated by the brake pad 45 during friction and achieving rapid heat dissipation of the brake pad 45.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
