[0007] ,
[0001] The utility model relates to the technical field of brake drums, and particularly relates to a light truck brake drum. <000,003>Background Technique
[0002] The light truck brake drum is a key component in the braking system of light trucks, mainly used to provide braking force to ensure that the vehicle can stop safely when needed. The brake drum is an iron casting similar to a tambourine in shape, fixed on the tire and rotating with the tire. When braking, the piston applies pressure to two pairs of semi-circular brake shoe pads, making them stick tightly to the inner wall of the drum chamber, thereby generating frictional force to stop the rotation of the wheel.
[0003] When the existing light truck brake drum is in use, the brake pads are closely attached to the inner wall of the drum chamber to generate frictional force to brake the vehicle. However, during the friction process, a large amount of heat will accumulate in the drum chamber, and the brake drum relies on itself for heat dissipation. This single heat dissipation effect is poor and cannot dissipate the heat in time, which will affect the service life of the brake drum. At the same time, cracks may occur and cause fractures, damaging the inner side of the wheel. Therefore, in view of the above problems, we propose a light truck brake drum. Content of the Utility Model
[0004] The purpose of the utility model is to provide a light truck brake drum to solve the problems that a large amount of heat will accumulate in the drum chamber during the friction process, and the brake drum relies on itself for heat dissipation. This single heat dissipation effect is poor and cannot dissipate the heat in time, which will affect the service life of the brake drum. At the same time, cracks may occur and cause fractures, damaging the inner side of the wheel.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A light truck brake drum includes a brake drum body and mounting holes. The mounting holes are opened on the inner side of the left end of the brake drum body. A heat conduction pipe is fixedly connected to the outer side of the right part of the brake drum body. An annular heat dissipation fin is fixedly connected to the outer side of the heat conduction pipe. Ventilation holes are opened on the inner side of the annular heat dissipation fin. An annular flow equalizing plate is fixedly connected to the outer side of the brake drum body. A protective shell is fixedly connected to the outer side of the left part of the brake drum body. A cold air blower is fixedly connected to both the upper and lower ends of the protective shell. A ventilation pipe is fixedly connected to one end of the cold air blower close to the protective shell. The right end of the ventilation pipe is fixedly connected to an air outlet. An installation groove is opened on the outer side of the protective shell, and a metal filter screen is fixedly connected to the inside of the installation groove.
[0007] Preferably, the cross-sectional shape of the brake drum body is an inverted "convex" shape, and the number of mounting holes is four.
[0008] Preferably, the heat pipe is located on the right side of the annular flow equalizer, the number of annular heat sinks is several, the number of ventilation holes is several, and the annular heat sinks are evenly arranged.
[0009] Preferably, the annular flow equalizer is located on the right side of the air outlet, a protective shell is fixedly connected to the outside of the annular flow equalizer, and the annular heat sink is located inside the protective shell.
[0010] Preferably, there are two air coolers, a protective shell is fixedly connected to the outside of the ventilation pipe, and the metal filter is located outside the annular heat sink.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, by setting up a heat-conducting pipe, annular heat sink, ventilation holes, annular flow equalizer, cooler, ventilation duct, and air outlet, the heat-conducting pipe can quickly conduct heat generated by the brake drum body during braking. The annular heat sink increases the heat dissipation area. When the cooler is turned on, it blows cold air out through the ventilation duct and air outlet, accelerating airflow. The annular flow equalizer spreads the cold air evenly to the right, exchanging heat on the annular heat sink and allowing heat to be discharged in time. The ventilation holes can accelerate the flow of cold air to the right, thereby accelerating the overall cooling speed of the brake drum body, reducing heat accumulation, and extending service life. By setting up a protective shell, mounting groove, and metal filter, when the brake drum body develops a crack and suddenly breaks, the protective shell and metal filter intercept the broken brake drum body, reducing the damage to the inner side of the wheel caused by the sudden breakage of the brake drum body. The mounting groove can reduce the obstruction of natural wind and also allow the air after heat exchange to be discharged from the mounting groove. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-7 This utility model provides a technical solution:
[0023] A light truck brake drum includes a brake drum body 1 and a mounting hole 2. The mounting hole 2 is provided on the inner side of the left end of the brake drum body 1. A heat conduction pipe 3 is fixedly connected to the outer side of the right part of the brake drum body 1. An annular heat sink 4 is fixedly connected to the outer side of the heat conduction pipe 3. A ventilation hole 5 is provided on the inner side of the annular heat sink 4. An annular flow equalization plate 6 is fixedly connected to the outer side of the brake drum body 1. A protective shell 7 is fixedly connected to the outer side of the left end of the brake drum body 1. A cold air fan 8 is fixedly connected to both the upper and lower ends of the protective shell 7. A ventilation pipe 9 is fixedly connected to the end of the cold air fan 8 near the protective shell 7. An air outlet 10 is fixedly connected to the right end of the ventilation pipe 9. An installation groove 11 is provided on the outer side of the protective shell 7. A metal filter screen 12 is fixedly connected inside the installation groove 11.
[0024] The brake drum body 1 has an inverted "U" shaped cross-section. It has four mounting holes 2. Heat pipes 3 are located to the right of the annular flow equalizer 6. There are several annular heat sinks 4 and several ventilation holes 5. The annular heat sinks 4 are evenly distributed. The annular flow equalizer 6 is located to the right of the air outlet 10. A protective shell 7 is fixedly connected to the outside of the annular flow equalizer 6. The annular heat sinks 4 are located inside the protective shell 7. There are two air coolers 8. The protective shell 7 is fixedly connected to the outside of the ventilation pipes 9. A metal filter 12 is located outside the annular heat sinks 4. The brake drum body 1 has an opening on the inner side of its left end. A mounting hole 2 is provided, and a heat-conducting pipe 3 is fixedly connected to the outer right side of the brake drum body 1. This facilitates the installation of the heat-conducting pipe 3, annular heat sink 4, ventilation hole 5, annular flow equalizer 6, air cooler 8, ventilation pipe 9, and air outlet 10. The heat-conducting pipe 3 can quickly conduct the heat generated by the brake drum body 1 during braking. The annular heat sink 4 increases the heat dissipation area. When the air cooler 8 is turned on, it blows out cold air through the ventilation pipe 9 and air outlet 10, accelerating airflow. The annular flow equalizer 6 evenly diffuses the cold air to the right, dissipating the heat on the annular heat sink 4. The ventilation holes 5 allow for timely heat dissipation, accelerating the flow of cool air to the right and thus speeding up the overall cooling of the brake drum body 1, reducing heat accumulation, and extending its service life. A ring-shaped heat sink 4 is fixedly connected to the outside of the heat pipe 3, with ventilation holes 5 on the inner side of the ring-shaped heat sink 4. A ring-shaped flow equalizer 6 is fixedly connected to the outside of the brake drum body 1, and a protective shell 7 is fixedly connected to the outer left side of the brake drum body 1. This facilitates the installation of the protective shell 7, mounting groove 11, and metal filter screen 12. In the event of a sudden breakage due to a crack in the brake drum body 1, the protective shell... 7 and the metal filter 12 intercept the broken brake drum body 1, reducing the damage to the inner side of the wheel caused by the sudden breakage of the brake drum body 1. The mounting groove 11 can reduce the obstruction of natural wind and allow the air after heat exchange to be discharged from the mounting groove 11. Both the upper and lower ends of the protective shell 7 are fixedly connected to the air cooler 8. The end of the air cooler 8 near the protective shell 7 is fixedly connected to the ventilation pipe 9. The right end of the ventilation pipe 9 is fixedly connected to the air outlet 10. The protective shell 7 has a mounting groove 11 on the outside, and the metal filter 12 is fixedly connected inside the mounting groove 11.
[0025] Working process: When the device is in use, it is powered by an external power source. The wheel bolts are passed through the mounting hole 2 and engaged with the wheel nut, so that the brake drum body 1 is installed inside the wheel. During braking, the brake pads are pressed against the inner wall of the brake drum body 1 to generate friction and brake the vehicle. This causes a large amount of heat to be generated inside the brake drum body 1. At this time, the heat conduction pipe 3 can quickly conduct the heat from the brake drum body 1. Then, the annular heat sink 4 increases the heat dissipation area. The cooling fan 8 is started by the external controller. The cooling fan 8 blows cold air out through the ventilation pipe 9 and the air outlet 10, accelerating the airflow. The annular flow equalizer 6 evenly diffuses the cold air to the right, and the ventilation hole 5 accelerates the airflow. The cold air flows to the right, reducing the obstruction of the cold air by the annular heat sink 4, thereby enabling rapid heat exchange on the annular heat sink 4 and timely heat dissipation. This accelerates the overall cooling speed of the brake drum body 1, reduces heat accumulation, and extends service life. When the brake drum body 1 suddenly cracks and breaks, the protective shell 7 and the metal filter 12 intercept the broken brake drum body 1, reducing the damage to the inner side of the wheel caused by the sudden breakage of the brake drum body 1. The mounting slot 11 can reduce the obstruction of natural wind and allow the air after heat exchange to be discharged from the mounting slot 11. The metal filter 12 can filter dust in the air.
