I. Undervalued safety line: Why do commercial vehicle wipers need to be more professional?<\/h2>

Statistics show that up to 83% of traffic accidents on rainy days directly relate to blurred vision. For commercial vehicles that can carry dozens of passengers and weigh more than ten tons, an unqualified wiper puts the safety of every passenger at risk\u2014especially in extreme conditions like heavy rain and snow, where you are essentially betting on a single rubber strip.<\/p>

There are fundamental differences between the windshield wiper requirements of commercial vehicles and passenger vehicles:<\/p>

II. Analysis of the five core components of the wiper system<\/h2>

A complete commercial vehicle wiper system relies on the following components working together, and a problem in any single part will cause the entire wiper to fail.<\/p>

2.1 Wiper motor<\/span><\/a><\/h3>

The wiper motor powers the entire system. Commercial vehicles typically use 24V permanent magnet DC motors with power ratings from 50W to 100W, and these motors must feature dual low-speed\/high-speed gears and intermittent wiping functions.<\/p>
