What is the power transmission route of an automobile chassis?
2 Answers
Power transmission route: clutch, transmission, angular transmission device, universal transmission device, rear drive axle, rear drive wheels. The following is relevant information: 1. Characteristics: facilitates the layout inside the vehicle body, reduces engine noise inside the cabin, eliminates the need for a long drive shaft, has a small front axle load, provides good adhesion, makes full use of the cabin area, but has poor heat dissipation. 2. Power transmission route for front-engine all-wheel drive: clutch, transmission, transfer case, universal transmission device divided into 4Wheel-Drive, separately reaching the front and rear drive axles, and finally transmitted to the front and rear drive wheels.
The power transmission path of a car's chassis is quite fascinating, like a stream of water flowing from its source to the destination. Power starts at the engine, where gasoline combustion generates energy. It then passes through the flywheel into the clutch or the torque converter of an automatic transmission—this component controls the connection between the engine and the wheels. In a manual transmission car, I can feel this process when I press the clutch to shift gears. After leaving the transmission, the power enters the driveshaft, a long rotating rod that transfers power to the rear differential. The differential acts like a smart distribution hub, ensuring the left and right wheels rotate at different speeds during turns to prevent skidding. Finally, the half-shafts deliver power to each wheel, making the car move. For front-wheel-drive vehicles, the drivetrain is more compact, with the engine and transmission positioned at the front, directly driving the front wheels. If any part of this path malfunctions—such as a worn driveshaft or dried-up differential fluid—the car may experience sluggish acceleration or shaking. Remember, regular maintenance, checking fluids and component wear, keeps the power transmission smooth.
