Description

Technical Field

[0001] The present invention relates to the technical field of mechanical transmission, and particularly to a mechanism for increasing torque. Background Art

[0002] Mechanisms for increasing torque are usually achieved by changing the transmission ratio, improving mechanical efficiency, or changing the characteristics of power output. The following are some common mechanisms for increasing torque and their principles:

[0003] 1. Gearbox (transmission)

[0004] Principle: The gearbox adjusts the relationship between the input and output speeds and torques through different gear ratios. In the low gear, the transmission increases the output torque by a larger gear ratio while reducing the speed; in the high gear, the torque decreases and the speed increases. Function: In the low gear, the torque increases, which is suitable for occasions such as starting and climbing that require large torque. In the high gear, it is suitable for high-speed driving.

[0005] 2. Force multiplier (such as hydraulic torque converter)

[0006] Principle: The force multiplier is a device that uses fluid to transmit power and is commonly used in automotive automatic transmissions. The hydraulic torque converter transmits power through a liquid (usually engine oil) between the impeller, turbine, and stator. The flow of the liquid multiplies the input torque. Function: It provides a large torque at low speeds, especially when starting and driving at low speeds, and can effectively increase the output torque.

[0007] The existing mechanisms for increasing torque use a method of increasing torque by using a weighted flywheel. However, the weighted flywheel used in the existing mechanisms for increasing torque is not adjustable. When the weighted flywheel is not adjustable, its moment of inertia is fixed. This means that it can only optimize the torque output within a specific speed range. For applications under different working conditions and load conditions, the fixed flywheel may not be able to fully play its role, resulting in insufficient torque output under certain working conditions, or excessive torque under other working conditions, affecting the smooth operation of the system.

[0008] In summary, in the prior art, there is a lack of technology for making the weighted flywheel of the mechanism for increasing torque adjustable. Summary of the Invention
