[0002] With the development of the times, people's economic life has become more and more superior, which has continuously improved the quality of people's food, clothing, housing and transportation. Therefore, the popularity rate of vehicles in reality is also getting higher and higher. When vehicles are in use, their ability to respond to real situations also needs to be continuously strengthened to respond to unexpected dangers in reality.

There are not only taxis and self-driving cars, etc., which make people's travel life more convenient and also increase people's life efficiency. However, there are many accidents in real life. Therefore, the braking performance needs to be improved. In the past technology, the brake drum was fixed on the wheel, and the friction block was pushed up by a pump to rub against the brake drum to achieve the effect of reducing speed. However, the braking efficiency of a single-layer brake is relatively low, and the effect of a single-sided brake drum is not good. After retrieval, it is found that the technical solution provided by the utility model with the application number 202322400126.5 also has the above problems. Summary of the Invention

By setting two pairs of bottom plates, the braking friction area can be increased. At the same time, the design of double-layer friction plates is adopted to enlarge the overall friction surface. At the same time, a brake wheel cylinder, a push rod, a top plate and a bottom plate are connected. When starting, the two friction plates can be pushed out to rub against the brake drum and the isolation plate respectively, increasing the friction surface, achieving the effect of reducing the friction time and quickly stopping the vehicle, which can greatly increase the safety factor.

[0026] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.

[0027] Refer to Figure 1-8 , an aluminum - magnesium alloy truck brake drum in an embodiment of the present utility model includes a bottom plate 1, a brake wheel cylinder 2 and a brake wheel 6. The front surface of the bottom plate 1 is fixedly connected with a top plate 4, the left surface of the top plate 4 is fixedly connected with a push rod 3, the rear surface of the brake wheel 6 is movably connected with a fixing plate 7, the rear surface of the fixing plate 7 is provided with a first fixing hole 8, the inner side wall of the first fixing hole 8 is threadedly connected with a fixing screw 9, the fixing screw 9 penetrates through the fixing plate 7 and is threadedly connected with a second fixing hole 5. The number of the fixing screws 9 is multiple. The multiple fixing screws 9 can increase the structural stability and facilitate disassembly at the same time.

[0028] A connecting block 10 is fixedly connected to the rear surface of the brake wheel cylinder 2. The brake wheel cylinder 2 is electrically connected to an external power source. A slider 11 is fixedly connected to the rear surface of the connecting block 10. A fixing block 12 is fixedly connected to the rear surface of the slider 11. A chute 17 is provided on the front surface of the bottom plate 1. A limiting plate 13 is fixedly connected to the side inner wall of the chute 17. The front surface of the connecting block 10 is slidably connected to the limiting plate 13. The side surface of the slider 11 is slidably connected to the chute 17. The front surface of the slider 11 is slidably connected to the limiting plate 13. The slider 11 can slide between the limiting plates 13. The connecting block 10 can slide in the chute 17. At this time, the positions of the fixing block 12 and the brake wheel cylinder 2 can be limited. The side surface of the connecting block 10 is slidably connected to the limiting plate 13. An isolation plate 16 is fixedly connected to the side inner wall of the brake wheel 6. An outer friction plate 14 is fixedly connected to the front surface of the bottom plate 1. An inner friction plate 15 is fixedly connected to the front surface of the bottom plate 1. The output end of the brake wheel cylinder 2 is fixedly connected to a push rod 3. By means of the brake wheel cylinder 2, the bottom plate 1 can be pushed, and the inner friction plate 15 and the outer friction plate 14 can be pushed out to contact the brake wheel 6 and the isolation plate 16 respectively for friction, achieving the braking effect. Neither the inner friction plate 15 nor the outer friction plate 14 contacts the isolation plate 16.

[0029] Working principle: During normal use, the overall brake wheel 6 rotates with the wheel, and the bottom plate 1 is fixed. There is a fixing block 12 in the middle for limiting. At this time, the inner friction plate 14 and the outer friction plate 15 do not contact the brake roll 6 and the isolation plate 16, so no frictional force is generated. When braking is used, the brake wheel cylinder 2 is started at this time, so as to push the push rod 3, and then drive the top plate 4 to push outwards on both sides, so that the bottom plate 1 moves outwards. At the same time, the inner friction plate 15 and the outer friction plate 14 are respectively moved outwards towards the isolation plate 16 and the outside of the brake wheel 6. When the friction plates 15 and the outer friction plates 14 contact the isolation plate 16 and the brake wheel 6 respectively, friction can be generated between the friction plates 15, the outer friction plates 14 and the isolation plate 16 and the brake wheel 6, so as to achieve the effect of reducing the speed of the brake wheel, thereby reducing the speed of the wheel and achieving the braking effect. When using the brake wheel cylinder 2, because there is a slider 11 moving in the chute 17 and there is a fixing block 12 connecting the two brake wheel cylinders, the brake wheel cylinder 2 will not move around and fall off. When replacement is needed, unscrew the fixing screw 9 and install a new outer friction plate 14, inner friction plate 15 or other structures.

[0030] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
