Description

Technical Field

[0001] This invention belongs to the field of power transmission and relates to a method and device for preventing the reverse transmission of inertia. Background Technology

[0002] In many existing transmission mechanisms, the power output end, under the influence of inertia, generates a force that acts in reverse on the input end, making it difficult to control the power input end. In severe cases, this can lead to overall loss of control. Examples include stopping a robotic arm during movement, losing control of a ship during anchoring, brake failure in a tower crane during operation, and brake failure in a heavy truck traveling downhill for extended periods. Under the influence of gravity, the truck accelerates, and prolonged use of the braking system can cause it to malfunction, leading to dangerous situations. Summary of the Invention

[0003] To address the aforementioned issues, a method and apparatus for preventing the reverse transmission of inertia are provided, ensuring that the power input section is unaffected by the inertia of the power output section, thereby making the transmission structure easier to control and safer.

[0004] According to one aspect of the present invention, a method for preventing the reverse transmission of inertia is provided: constructing a secondary gear, the secondary gear being composed of two gears of different sizes fixedly connected, the inner sides of the two or more secondary gears respectively meshing with a fixed gear and an output gear, the axis of the fixed gear and the axis of the output gear coinciding, the fixed gear being fixedly mounted on a housing, taking the revolution of the two or more secondary gears as input, and through the design of the transmission ratio between the secondary gear, the fixed gear, and the output gear, causing the output gear to rotate and output.

[0005] With this structure, the revolution of the secondary gear generates the rotation of the output gear. When the output gear changes speed due to inertia, it will cause the rotation of the secondary gear to change. At this time, due to the action of the fixed gear, the acceleration or deceleration of the rotation of the secondary gear will be prevented, so that the output gear can only maintain the speed given by the revolution input of the secondary gear.

[0006] As an alternative technical solution, the fixed gear and the output gear can be replaced by two internal gear rings, namely a fixed gear ring and an output gear ring.

[0007] As an alternative technical solution, the secondary gear can be composed of two bevel gears fixedly connected, and the fixed gear and the output gear are respectively a fixed bevel gear and an output bevel gear, and the fixed bevel gear and the output bevel gear mesh on the same side of the secondary bevel gear.

[0008] While this structure achieves the limitation of inertia, some scenarios, such as vehicle gear shifting, do not allow the power output to lock due to the lack of input when the input power is interrupted. Therefore, a further technical solution is proposed. As a further technical solution: Construct a second power transmission path, where the power output end is engaged and then the power is transmitted back to the input end through a clutch. By disengaging and engaging the clutch, the interruption or connection of the transmission of inertial power from the power output end to the power input end can be controlled.

[0009] With this structure, when the vehicle is driving normally or shifting gears, the clutch can be closed, forming two paths to transmit power. When the vehicle is driving downhill for a long time, the clutch can be disengaged, forming only one path to transmit power, thus preventing the effects of inertia.

[0010] As an alternative technical solution, the clutch in the second power transmission path can be replaced by a synchronizer or a braking device.

[0011] According to another aspect of the present invention, a device for preventing the reverse transmission of inertia is provided, comprising a housing and an input shaft, wherein the input shaft is rotatably disposed on the housing; A first rotating frame is rotatably mounted on the housing; The second rotating frame is rotatably mounted on the housing, and is fixedly connected to the first rotating frame and the input shaft. A secondary planetary gear, which is composed of two gears of different sizes fixedly connected, with the axis lines of the two gears of different sizes coinciding. The two ends of the secondary planetary gear are respectively rotatably mounted on the first rotating frame and the second rotating frame, and two or more secondary planetary gears are evenly distributed on the first rotating frame and the second rotating frame. A fixed gear is fixedly mounted on the housing and meshes with one of the plurality of secondary planetary gears. An output gear that meshes with another gear among the plurality of second-stage planetary gears; An output shaft is fixedly connected to the output gear, and the output shaft is rotatably mounted on the housing, passing through the center of the fixed gear; The first transmission gear is fixedly mounted on the output shaft; A drive shaft, which is rotatably mounted on the housing; The second transmission gear is fixedly mounted on the transmission shaft and meshes with the first transmission gear. The third transmission gear is rotatably mounted on the transmission shaft; A clutch, wherein the clutch connects the drive shaft to the third drive gear; The fourth transmission gear is fixedly mounted on the input shaft and meshes with the third transmission gear.

[0012] According to another aspect of the present invention, a second device for preventing reverse inertial conduction is provided, comprising a housing and an input shaft, the input shaft being rotatably mounted on the housing; An input gear is fixedly mounted on the input shaft; A second-stage planetary gear, wherein the second-stage planetary gear is composed of two gears of different sizes fixedly connected, the axis lines of the two gears of different sizes coincide, and one of the two or more second-stage gears meshes with the first output gear; The third rotating frame and the fourth rotating frame are rotatably connected to a plurality of the secondary planetary gears, and the plurality of the secondary planetary gears are evenly distributed on the third rotating frame and the fourth rotating frame; A fixed internal gear ring is fixedly mounted on the housing. The fixed internal gear ring meshes with one of the multiple secondary planetary gears. The secondary planetary gear meshed with the fixed internal gear ring is the same type of gear as the first input gear.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1 like Figure 1 As shown, a device for preventing the reverse transmission of inertia includes a housing 1; Input shaft 2, which is rotatably mounted on housing 1; The first rotating frame 4 is rotatably mounted on the housing 1; The second rotating frame 3 is rotatably mounted on the housing 1. The second rotating frame 3 is fixedly connected to the first rotating frame 4 and the second rotating frame 3 is fixedly connected to the input shaft 2. The second-stage planetary gear 5 is composed of two gears of different sizes fixedly connected, with the axis lines of the two gears of different sizes coinciding. The two ends of the second-stage planetary gear 5 are respectively rotatably mounted on the first rotating frame 4 and the second rotating frame 3. Two or more second-stage planetary gears 5 are evenly distributed on the first rotating frame 4 and the second rotating frame 3. A fixed gear 6 is fixedly mounted on the housing 1, and the fixed gear 6 meshes with one of the multiple secondary planetary gears 5; Output gear 7, which meshes with another gear among the plurality of secondary planetary gears 5; Output shaft 8 is fixedly connected to output gear 7. Output shaft 8 is rotatably mounted on housing 1 and passes through the center of fixed gear 6.

[0016] In this embodiment, the input shaft 2, the first rotating frame 4, and the second rotating frame 3 are all rotatably mounted on the housing 1. Two or more secondary planetary gears 5 are rotatably mounted on the first rotating frame 4 and the second rotating frame 3. The input shaft 2 is fixedly connected to the second rotating frame 3. The input shaft 2 inputs power to make the two or more secondary planetary gears 5 revolve. The fixed gear 6 is fixedly mounted on the housing 1. The output gear 7 meshes with two or more secondary planetary gears 5. The output gear 7 is fixedly connected to the output shaft 8. The input shaft 2 inputs power to make the secondary planetary gears 5 revolve. Through the transmission ratio design between the fixed gear 6, the output gear 7, and the secondary planetary gears 5, the output shaft 8 forms a self-rotating output. If the output part needs to produce a speed change under the action of inertia, it will cause the self-rotation of the secondary planetary gears 5 to change. At this time, due to the action of the fixed gear 6, the secondary planetary gears 5 cannot produce a speed change due to self-rotation. That is, the output shaft 8 can only maintain the speed given by the input shaft 2.

[0017] As a further technical solution, a first transmission gear 9 is fixedly mounted on the output shaft 8; A drive shaft 10 is rotatably mounted on the housing 1; The second transmission gear 11 is fixedly mounted on the transmission shaft 10 and meshes with the first transmission gear 9. The third transmission gear 12 is rotatably mounted on the transmission shaft 10; The fourth transmission gear 13 is fixedly mounted on the input shaft 10 and meshes with the third transmission gear 12. Clutch 14, which connects the drive shaft 10 and the third drive gear 12.

[0018] In this embodiment, the first transmission gear 9 meshes with the second transmission gear 11, the fourth transmission gear 13 meshes with the third transmission gear 12, and the third transmission gear 12 is connected to the transmission shaft 10 through a clutch 14. When the clutch 14 is disengaged, the force generated by the inertia of the output shaft 8 cannot be transmitted back to the input shaft 2. When the vehicle needs to shift gears, the clutch 14 is engaged. At this time, the power of the input shaft is interrupted, and the power of the output shaft 8 is transmitted back to the input shaft in the reverse direction, so that the vehicle continues to drive under the action of inertia. Specific Implementation Example 2 like Figure 2 As shown, a device for preventing the reverse transmission of inertia includes a housing 15; Input shaft 16, which is rotatably mounted on the housing 15; An input gear 17 is fixedly mounted on the input shaft 17. Secondary gear 18, two or more of the secondary gears 18 mesh with the input gear 17; The third rotating frame 19 and the fourth rotating frame 20, the two sides of the secondary gear 18 are respectively rotatably mounted on the third rotating frame 19 and the fourth rotating frame 20, and a plurality of the secondary gears 18 are evenly distributed on the third rotating frame 19 and the fourth rotating frame 20; A fixed internal gear ring 21 is fixedly mounted on the housing 15 and meshes with a plurality of secondary gears 18. An internal gear ring 22 is rotatably mounted on the housing 15 and meshes with a plurality of secondary gears 18. Output shaft 23, which is fixedly connected to the output internal gear ring 22.

[0020] In this embodiment, the input shaft 16 is rotatably mounted on the housing 15, the fixed internal gear ring 21 is fixedly mounted on the housing 15, the input gear 17 is fixedly connected to the input shaft 16, and the secondary gear 18 meshes with the fixed internal gear ring 21 and the input gear 17 respectively. Thus, the input shaft 16 inputs power, causing the secondary gear 18 to rotate in a superimposed orbital motion. The output internal gear ring 22 meshes with the secondary gear 18, and the output shaft 23 is fixedly connected to the output internal gear ring 22. Therefore, the power input from the input shaft 16 is transmitted through the transmission... Under the condition of the ratio, the output shaft 23 rotates and outputs; and the output internal gear ring 22 and the fixed internal gear ring 21 both mesh with the secondary gear 18 on the same side. Under the action of inertia, the output internal gear ring 22 will cause the rotation of the secondary gear 18 to change. Due to the action of the fixed internal gear ring 21, the force arm applied by the output internal gear ring 22 to the secondary gear 18 relative to the fixed internal gear ring 21 is zero, so it is locked. That is, the output internal gear ring 22 can only maintain the speed given by the input shaft 16 and cannot realize the reverse power transmission.

[0021] As a further technical solution, a fifth transmission gear 24 is fixedly mounted on the output shaft 23; A drive shaft 25 is rotatably mounted on the housing 15; The sixth transmission gear 26 is fixedly mounted on the transmission shaft 25 and meshes with the fifth transmission gear 24. The seventh transmission gear 27 is rotatably mounted on the transmission shaft 25; The eighth transmission gear 28 is fixedly mounted on the input shaft 16 and meshes with the seventh transmission gear 27. Clutch 29, which connects the drive shaft 25 and the seventh drive gear 27 respectively.

[0022] In this embodiment, the fifth transmission gear 24 is fixedly mounted on the output shaft 23, the transmission shaft 25 is rotatably mounted on the housing 15, and the sixth transmission gear is fixedly mounted on the transmission shaft 25. Thus, the rotation of the output shaft 23 drives the rotation of the transmission shaft 25. The seventh transmission gear 27 is rotatably connected to the transmission shaft 25, and the eighth transmission gear 28 is fixedly connected to the input shaft 16. The seventh transmission gear 27 and the eighth transmission gear 28 mesh. The seventh transmission gear 27 and the transmission shaft 25 are connected through a clutch 29, which serves as the second power transmission path. When the clutch 29 is disengaged, the inertial power at the output end cannot be reversed and transmitted back to the input end, such as when the vehicle's brakes fail on a long downhill slope. When the clutch 29 is engaged, the power at the output end can reversely transmit the inertial power back to the input end, such as when the vehicle is shifting gears.

[0023] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
