Description

Power transmission

This model is a gear shifting device, especially a power shifting device.

According to the general traditional gearbox, by changing the speed ratio between the engine and the wheels, the engine's relatively not-wide power band can be adapted to the very complex and changeable needs of our driving power. Therefore, when changing the gearbox gear, it means the same wheel speed, the engine speed will change, from a certain speed in one gear to another speed in the next gear.

If the engine speed is pulled higher or lowered, if it is not handled properly, the engine speed will change suddenly when shifting. The inertia of the moving parts inside the engine will react on the car body, and a small part of the vibration will be directly from the vehicle body. The engine suspension is transferred to the body, and the rest is transferred from the flywheel to the gearbox, then to the drive shaft, and finally to the wheels.

Refer also to Figure 8 for a schematic diagram of the action of this creative free gear. Each free gear 15 is pivoted between the rotating discs 10, and each of the free gears 15 is mainly located between the first sprocket 120 and the second sprocket 140. Since each of the gears 15 only meshes with the chain 17, it can exhibit idling. status. It can be seen from the above that the power input shaft 2 mainly drives the sprocket 16 and continues to provide power. When the gearbox device 5 is not activated, the respective gears 15 are simultaneously driven through the chain 17 because the respective gears 15 rotate independently. Therefore, it will not mesh with the first driving gear 11 and the second driving gear 13. At this time, in order to prevent the chain 17 and other sprockets from being frustrated or even damaged during the rotation, the chain 17 and the driving sprocket 14 are connected, and the chain 17 and The free gear 15 is meshed. Since the free gear 15 is not affected by any external force, it can rotate freely, allowing the chain 17 to remain engaged before the free gear 15 is engaged, so as to reduce the aforementioned frustration and even structural damage.

The aforementioned power output shaft group 18 is mainly connected to the gearbox device 5. The first output shaft 180 and the second output shaft 182 in the power output shaft group 18 respectively drive gear mechanisms with different gear ratios. When the first output shaft needs to be activated When the gear mechanism is connected to 180, the rotating disc 10 is driven by the motor 19 connection. At this time, the rotating disc 10 rotates so that the first interlocking gear 12, the second interlocking gear 14, and the free gear 15 rotate simultaneously, and are fixed to the first output shaft 180 The first driving gear 11 is mainly meshed with the first interlocking gear 12. When the first sprocket 120 is linked via the chain 17 to rotate the first interlocking gear 12, the first driving gear 11 meshing with the first interlocking gear 12 is The synchronous rotation then drives the first output shaft 180 to operate the linked gear mechanism.

In addition to the first type of speed change described above, when the second type of speed change is required, that is, when the second output shaft 182 drives the gear mechanism corresponding to the gear ratio, the motor 19 acts again and connects to drive the rotating disc body 10. The rotating disc 10 rotates again. At this time, the first interlocking gear 12 that originally meshed with the first driving gear 11 is disengaged, and the second interlocking gear 14 is rotated while the rotating disc 10 rotates and interacts with the second driving gear. 13 meshes, and the second driving gear 13 drives the second output shaft 182 in the power output shaft group 18 to rotate, so as to achieve the start of the second speed change.

It is worth mentioning that the aforementioned chain 17 can be an elastic chain, which is mainly retracted by the force of a spring to reduce vibration and noise during the operation of the engine. Because the chain is elastic, it can absorb Vibration achieves the principle of dual mass flywheel.

Furthermore, one end of the aforementioned tension adjusting member 3 is provided with a tension gear 30. The tension gear 30 is mainly meshed with the chain 17, and an elastic force is generated toward the chain 17 through the tension adjusting member 3. When the chain 17 rotates the disc assembly 10 to shift speed It will expand or contract during operation. The tension state of the chain 17 can be controlled by the tension adjuster 3, and the tension gear 30 meshes with the chain 17 to help the chain 17 adjust the tension and fix the front and back at the same time. Direction of transmission.

Please also refer to FIG. 9, which is a schematic diagram of the structure of a chain combined with a first interlocking gear and a second interlocking gear for this creation. In this embodiment, the first sprocket 120 on the side of the first interlocking gear 12 is a plurality of side-by-side arranged and linked to the chain 17 respectively. The second sprocket 140 on the side of the second interlocking gear 14 is a plurality of side-by-side arranged and linked to the chain 17 respectively. The first sprocket 120 and the second sprocket 140 are arranged side by side as an example. The relative free gear 15 and the driving sprocket 14 are arranged corresponding to the number of the first sprocket 120 and the second sprocket 140. When three chains are set The overall operation method at 17:00 is the same as the above, but it can increase the pulling force effect during the overall operation. For example, the pulling force of a single chain 17 is 3N, when the chain 17 is three, the pulling force is increased to 9N, so that the overall operation greatly reduces the breakage risks of.

It can be seen from the above that this creation mainly uses the rotating disc set 10, the first driving gear 11, the first interlocking gear 12, the second driving gear 13, the second interlocking gear 14, the plural free gears 15, the plural driving sprockets 16, and The combination of at least one chain 17 (which is an elastic chain), the power output shaft set 18 and the housing 19 effectively improves the shortcomings of traditional clutches that transmit power through friction, which is too large and easy to slip, and can reduce the space of traditional clutches.
