Automotive Transmission Assembly
★Exhibit Content: Automotive Transmission Mechanism ★Interaction: Mechanical ★Exhibit Description: The exhibit consists of a display stand, a handwheel, an interactive mechanism, and a protective cover. By turning the handwheel, visitors can clearly see the transmission process of the internal mechanisms of an automobile. They can learn about the working principles of the automotive clutch, automotive steering gear, and automotive differential, presenting scientific knowledge applied to real life in a more intuitive way. ★★Clutch★Operation: 1. Turn the handwheel to observe the structural movement of the clutch; 2. Lift the shift lever to observe the positional changes of the pressure spring and pressure plate (friction plate). ★Function Overview: The exhibit consists of an automotive clutch demonstration mechanism and an operating device. It shows the basic structure and working principle of an automotive clutch. ★Scientific Principle: How does a clutch work? The clutch is located between the engine and the gearbox, used to transmit the torque stored on the engine flywheel to the gearbox, ensuring that the vehicle transmits an appropriate amount of driving force and torque to the drive wheels under different driving conditions. ★★Steering Gear★Operation: Turn the steering wheel left and right to observe changes in the wheel steering state. ★Function Overview: The exhibit consists of an operating device and an automotive steering gear demonstration mechanism. Visitors can turn the steering wheel left and right to observe the process of wheel steering changes. ★Scientific Principle: How does the steering wheel drive the wheels to steer? There are many types of automotive steering mechanisms. This structure demonstrates a worm and crank pin steering mechanism, which uses a worm as the driving component and a crank pin as the driven component. ★★Differential★Operation: 1. Turn the handwheel to start the differential rotating, and observe the speed of the wheels at both ends of the differential; 2. Use your hand to slightly resist one side of the running wheel, and observe the speed changes of the wheels on both sides. ★Function Overview: The exhibit consists of an automotive differential demonstration mechanism, an operating device, a protective cover, etc. Visitors can turn the handwheel to start the differential rotating and observe the speed of the wheels at both ends of the differential; by using a hand to slightly resist one side of the running wheel, they can observe the changes in the rotational speed of the wheels on both sides. ★Scientific Principle: Why can a car turn smoothly when cornering? The differential is composed of planetary gears, a planetary gear carrier, side gears, and other parts. The engine power enters the differential through the drive shaft, directly driving the planetary gear carrier, which then drives the left and right half-shafts through the planetary gears, separately driving the left and right wheels. The design requirement of the differential is: left half-shaft speed + right half-shaft speed = 2 times the planetary gear carrier speed. When the car is driving straight, the speeds of the left wheel, right wheel, and planetary gear carrier are equal and in a balanced state. When the car turns, this balanced state is disrupted, causing the inner wheel speed to decrease and the outer wheel speed to increase, allowing the car to turn smoothly.
