What are the hazards of vehicle undercarriage scraping?
2 Answers
Vehicle undercarriage scraping can cause the following hazards: 1. Oil pan rupture: The transmission oil pan, usually made of aluminum alloy, is responsible for lubricating oil circulation and is extremely prone to rupture during scraping, leading to oil leakage; 2. Damage to electronic pipelines in the chassis: When scraping occurs, the electronic pipelines in the vehicle's undercarriage may be damaged; 3. Brake fluid pipe leakage: The braking system, which significantly impacts vehicle safety, is a crucial guarantee for automobile safety. Modern vehicles widely use hydraulic braking systems, where factory-installed brake fluid pipes are rarely made of metal nylon tubes but are generally rubber pipes. Therefore, when undercarriage scraping occurs, one should immediately consider whether the brake fluid pipes have ruptured.
Don't underestimate the issue of scraping the undercarriage. Once while driving on a rural road, I didn't notice a protruding rock and ended up with a loud 'clunk' as the chassis scraped directly. At the time, it felt like just a minor bump, but the next day I found engine oil leaking everywhere. Upon inspection, I discovered the oil pan had been punctured. To make matters worse, part of the exhaust pipe was crushed, causing a constant buzzing noise when accelerating. The scariest part was when a friend's car had its brake line rupture after scraping the undercarriage, nearly causing an accident. Now I understand that the undercarriage houses various critical components: the engine, fuel tank, drive shaft—any of these getting hit could lead to serious problems. That's why it's essential to observe the road ahead while driving, especially slowing down when going over bumps or potholes. If undercarriage scraping does occur, immediately check for any fluid leaks or deformations underneath the vehicle.
