Working principle of motorcycle gearbox
Author:
The principle of the transmission is that when the transmission pedal assembly is depressed, the transmission shaft rotates accordingly. The shift arm body S, which is welded to the transmission shaft, swings accordingly. The shift arm is connected to the shift arm body by a pin, and the shift arm is always pulled upward by a spring.
The working principle of the transmission is that when the transmission pedal assembly is depressed, the drive shaft rotates, and the shift arm body S welded to the drive shaft swings accordingly. The shift arm is connected to the shift arm body with a pin, and the shift arm is always pulled upward by a spring.
Because the other end of the shift arm has a groove, and there are two locating pins in the groove, under the action of the spring, the shift arm always presses against the locating pins. The locating pins are pulled or pushed by the action of the groove hook, moving along the direction of movement of the shift arm.
This is a disassembled four-speed transmission. Basically, motorcycles use this structure, only the number of gears is increased. Motorcycles mostly use spur gears, which have a simple structure.
Gear shifting is easy to understand. A small gear driving a large gear means more torque and slower speed (first gear). A large gear driving a small gear means faster speed and less torque (higher gear). The transmission ratio is usually described in the instruction manual.
These gears are always engaged. Actually, some gears are loosely fitted on the shaft and only rotate without transmitting power. The power is transmitted by a movable gear that is connected to the main shaft via splines and can move left and right while still transmitting power.
The function of the transmission: When a motorcycle is running, the road conditions are constantly changing, and it is necessary to frequently change the speed and traction of the vehicle. For example, on flat roads, the vehicle can run faster. On uneven roads or slopes, due to the large driving resistance, the speed must be reduced to increase the traction of the vehicle.
