The one who has the most contact with cars is probably a taxi driver. They have to deal with their own cars every day, shifting gears and stepping on the clutch at least 2000 times while driving. How can I free my left foot and shift gears manually? A taxi driver from Kunming has invented a clutch that is easy to operate and fuel-efficient.
It is said that this taxi driver began to ponder this matter more than 10 years ago, when he began trying to improve the clutch device and replace some simple car clutch accessories based on his usual driving and repair experience. Why I came up with this invention is actually because driving a taxi is quite tiring, and then my left foot can free it, from the principle of bicycles to cars.
The bicycle flywheel is unidirectional. As long as you ride hard for a while, with inertia, the bicycle can continue to move forward for a distance, and the human foot can temporarily rest. Later, it was borrowed from the principle of a small flywheel on a bicycle and used one-way transmission of power. When the driver refuels, the clutch plate follows the engine with the wheels running synchronously at the same speed; When releasing the accelerator, the clutch plate and some automotive clutch accessories can prevent the high-speed running engine from being affected by the reduction of idle speed and the obstruction of the generated reverse tension, allowing the wheels to continue moving forward with the help of inertia, thus achieving the goal of fuel saving.
Later on, he bought a traditional clutch plate to study its structure, and how to add a one-way locking device to it. After installing it, he also succeeded and found some technicians to modify it with him. He took it to the car for testing, but the lifespan was not long enough. After 10 years of continuous improvement in its structure and materials, it can now reach over 30000 kilometers. It is only now being pushed to the market.
If you are an expert in the car, you will find that modifying this type of clutch is very simple, and you don't need to make major changes to the original car. You only need to replace some of the car's clutch accessories. If replaced with this newly invented clutch, the driver can basically no longer press the clutch while driving, and can directly shift up or down, which is very convenient and labor-saving.
