Shared bicycle can be a household name, in the sharing economy has been a major trend, compared to life we also feel the convenience brought by shared bicycle, then today I give you the basic knowledge of shared bicycle, gear shaft drive and chain drive.
I think the chain drive we all know, is also the most common before, today I focus on introducing you to the gear shaft drive, careful observation we can find gear transmission of the sharing bicycle also more and more, such as the common Mobay has a gear transmission, so why more and more businessmen give up the traditional chain drive and choose the current gear transmission?
First of all, to popularize the gear shaft, gear shaft refers to the mechanical parts that support the rotating parts and rotate together with them to transmit motion, torque or bending moment. Generally for the metal round rod-shaped, each segment can have different diameters. The parts of the machine that make the rotary motion are mounted on the shaft.
So what are the advantages of gear shafts?
First, the efficiency of the shaft drive is significantly higher than that of the chain drive. The shaft drive is generally coupled with the internal variable speed of the rear axle, and these two are added together (instead of chain + external transmission).
second, we know that shared bikes are increasingly being destroyed, especially chain-driven shared bikes, and relatively speaking, shaft-driven bikes are more durable and less prone to destruction.
