The model can demonstrate the gear shifting process and can be powered on for rotation. Inertia flywheel: When the model is in neutral, it provides rotational inertia for the gear set, simulating the state of the car gliding in neutral Clutch drum: There are pressure springs, clutch plates, and friction plates inside Deceleration motor: The deceleration click provides power, the output shaft is a 0.5 modulus gear, and it is meshed with the clutch large gear for transmission Clutch plate: Friction plates are sandwiched between the clutch plates to increase friction and make power transmission more stable Small wrench: It plays the role of separating the clutch in the model The output end of the transmission model is equipped with a universal joint Four suction cups are designed at the bottom of the model, which can be fixed on a smooth desktop Push-pull rod: The push-pull rod extends from the gear selection period and directly links the gear fork Gear selector: The gear selector has 6 gears, adopts an H-type layout, and has a gear lock inside to prevent gear mismatch. Model: 5MT, manual transmission model Manufactured and assembled Parts: 3D printing Layer height 0.1~0.2mm Size: 170*80*98 (length\width\height+3mm) Applicable people: 16+
