U Bolt DXTB214 For MAN

Auxiliary fixation function in other systems
In addition to the core plate spring fixation, U-bolts also play an important fixing role in other parts of the car:
1. Fixing of exhaust pipeline
The exhaust system of a car (exhaust pipe, muffler) is usually suspended from the bottom of the car through U-bolts and lifting lugs. Here, the function of U-bolts is to:
Allow for thermal expansion and contraction: The exhaust system operates at high temperatures, which can cause thermal expansion and contraction. There is usually a flexible washer or a certain gap between the U-bolt and the exhaust pipe, allowing the pipeline to move longitudinally within a certain range, avoiding deformation or cracking of the pipeline due to thermal stress.
Vibration isolation and noise reduction: prevent the vibration of the exhaust system from being directly transmitted to the vehicle body, and improve driving comfort.
2. Connection of stabilizer bar (anti roll bar)
The stabilizer bar is connected to the lower suspension arm through a connecting rod (small pull rod), and its support fixed on the subframe or body is often in the form of U-bolts, which are easy to install and firm.
3. Fixing of other chassis components
Small U-shaped bolt structures are also used for fixing clamps of sensor harnesses, air pipes, or oil pipes to ensure that the pipeline runs neatly and reliably, avoiding interference with moving parts.
