What is the raised part in the rear of a car?
1 Answers
The raised part in the rear of a car is designed to provide space for the drive shaft or exhaust pipe to pass through, maintaining the flatness of the chassis. Below is relevant information: 1. Drive Shaft: The drive shaft is a high-speed, minimally supported rotating component, and its dynamic balance is crucial. Typically, drive shafts undergo dynamic balance testing before leaving the factory and are adjusted on a balancing machine. 2. Exhaust Pipe: The automotive exhaust bellows, also known as the exhaust pipe flexible hose, is installed between the engine exhaust manifold and the muffler. It allows the entire exhaust system to have flexible connections, thereby reducing vibration and noise, facilitating installation, and extending the lifespan of the exhaust muffler system.
