Dongfeng Xinjiang X7 truck parts AEBS radar cover plate 8406947-TXGG01Y

Built to guarantee unobstructed radar signal transmission—critical for AEBS’s collision avoidance function—the cover plate is made of high-performance modified PP material with carbon fiber reinforcement (15% fiber content). It features a low dielectric constant (≤2.5 at 77GHz, the working frequency of X7’s AEBS radar) and signal transmittance ≥98%, minimizing signal attenuation or reflection that could cause false alarms or detection failures. The surface is treated with a matte anti-reflective coating, which reduces sunlight glare interference by 60% compared to glossy covers, ensuring stable signal reception even in strong sunlight. In radar performance tests, the cover maintains the AEBS system’s detection range (up to 150m for moving vehicles, 50m for stationary obstacles) and accuracy (±0.5m distance error), fully complying with GB 7258-2017 automotive safety standards

Designed to shield the vulnerable AEBS radar module from road hazards, the cover plate integrates a robust impact-resistant structure. The main body (3mm thick) uses a double-layer PP composite design—an outer rigid layer (tensile strength ≥35MPa) to resist scratches and minor collisions, and an inner elastic layer to absorb impact energy. The edge of the radar window is reinforced with a 5mm-thick ABS frame, which can withstand 50J impact force (equivalent to a 2kg object falling from 2.5m) without cracking. The cover extends 12mm beyond the radar module’s edge, forming a protective barrier against rocks, gravel, and road debris that could damage the sensor’s lens. In field tests, it reduces radar module damage by 75% compared to unprotected installations, minimizing AEBS system downtime

Engineered to endure the diverse and harsh operating environments of commercial trucks, the cover plate delivers exceptional weather resistance and durability. The modified PP material tolerates extreme temperatures from -40℃ (frigid northern winters) to 80℃ (hot desert climates) without brittleness or deformation, maintaining structural stability through 1000 thermal cycles. It is resistant to UV radiation (2000-hour QUV test with no color fading or surface cracking), road salt, diesel fuel, and cleaning chemicals, preventing material degradation from long-term exposure. The anti-corrosion coating on the mounting holes (zinc-plated steel inserts) ensures no rust after 500-hour salt spray testing (ASTM B117), ensuring secure installation even in coastal or snowy regions. This durability guarantees the cover’s functionality for over 5 years of heavy-duty use

Optimized for efficient maintenance in truck fleet operations, the cover plate features a user-friendly design that simplifies installation and replacement. It uses a snap-fit structure combined with 4 pre-threaded mounting holes—align the cover with the bumper’s radar recess, press to engage the snaps, then tighten the M6 bolts (included in the package) to 8-10N·m with a standard Phillips screwdriver (no specialized tools needed). The package includes 4 galvanized M6×12 bolts and 4 rubber washers (to prevent vibration loosening), matching the X7’s original hardware specifications. Clear alignment marks (“TOP” and “LEFT”) on the cover’s inner surface prevent incorrect installation, ensuring the radar’s detection angle remains calibrated. A professional technician can complete the entire replacement process in 10 minutes or less, minimizing truck downtime and reducing maintenance costs for fleet operators
