Since the gearbox, there is already a hand-mounted, automatic mount design, where the self-altered split has developed a variable speed system, or a hand-in-shift system, however, they all have a common function: (1) Transfer engine Output power
(2) Change the combination of gears to cope with different needs now let's take a view of the basic construction of the handset allele: ▲ The gearbox input shaft is connected by the clutch, the gearbox input shaft warp the crankshaft, its function is input The driving force of the engine. ▲ The transmission of the transmission output shaft gearbox output shaft and the drive of the vehicle are directly connected together to use the power output. ▲ The mechanism of the gear unit is where the entire gearbox function is, which is where various gears are achieved by different combinations. ▲ The purpose of the synchronizer synchronizer is to help the shift gear can be synchronized to ensure smoothness in the gearbox shift operation. In fact, the gearbox is a quite high and complex machinery. It is not to produce gearboxes today. Maybe you don't believe, but these cars are handed over to companies specializing in design gearboxes. Production, whether it is hand-row, self-row, or hand-self-row-row gearbox, has a famous company in the specialty, such as the world's German ZF, M-Benz full car leveling box. ▲ The clutch clutch is a joining or separation of a special driving force. The hand-free speed box is used to "friction clutch", which produces a torque using the friction of the friction sheet to deliver the power. A grinding piece is connected to the power input, and the other is connected to the transmission output terminal. When two tight engages, the power is turned on, while two pieces are separated, the power is cut off. The meaning of the gear ratio and the important action of the importance gearbox is to replace different gear combinations. We can direct the gear position to change the relative seat of the gear, through the bite between the gears, to achieve the conversion "gear For the purpose of "(referred to as teeth ratio), complete the purpose of our shift. When we ride a mountain bike, we can experience it. When we want to start quickly, we can change the front wheel into small gears, replacement into large gears, then we can easily and quickly Start. With the increase in the speed of the bicycle, we will find how to step on the foot, and the speed is also limited. At this time, we can transform the rear wheel's gear is exchanged, and then replace the front wheel to a large gear. At this time, the feeling of the pedal is gains, but it is not necessary to step on so many turns, the speed of the bicycle can Faster ... The same reason, our car is not directly connected to the transmission axis, but is connected to the transmission axis of the transmission of the gearbox when designing the engine. Output. When the car starts, you need to overcome the static friction, and then drive the body move forward. At this time, it is necessary to make a large torque to help; then the low gear position (one gear) is similar to the start of the pedal, the front pinion, back The design of the gear, when the speed is getting faster, we don't have to need such a large torque output, when the high-speed file, the gearbox will replace the "back pinion, front large gear" when riding a bicycle.
