New Energy Power truck spare parts Power battery bracket A 2120211-TE8A0

Built to stably support heavy-duty battery packs (weight up to 800kg), the bracket delivers exceptional load-bearing performance. It is fabricated from high-strength low-alloy steel (Q550 grade) with a minimum yield strength of 550MPa and tensile strength of 670-830MPa—outperforming Q460 steel by 20% in load resistance. The 8mm-thick main frame integrates 10mm-thick triangular reinforcing ribs at stress points (mounting holes, bracket corners), distributing static and dynamic loads evenly across the chassis. Under dynamic road conditions (bumps, turns, emergency braking), the bracket maintains maximum deflection ≤1.5mm (at full load), preventing battery pack shifting that could damage electrical connectors or cell modules. In static load tests, it withstands 1200kg (150% of rated load) for 24 hours without permanent deformation

Engineered to protect the battery pack from external impacts and mechanical damage, the bracket features a comprehensive protective design. The front edge is equipped with a 12mm-thick steel bumper that absorbs impact energy (up to 50J) from road debris or minor collisions, preventing direct force transmission to the battery casing. The supporting surface integrates rubber cushioning pads (EPDM material, 5mm thickness) that reduce vibration transfer by 40% and prevent metal-to-metal contact between the bracket and battery. Side guardrails (height 80mm) limit lateral movement of the battery pack during sharp turns, while drainage holes (12mm diameter) at the bottom prevent water accumulation that could cause corrosion. The bracket’s open-frame design also facilitates heat dissipation from the battery pack, avoiding overheating risks

Designed for the rigorous operating environments of commercial NEVs, the bracket exhibits exceptional durability across diverse climates and road conditions. It undergoes a four-step anti-corrosion process: zinc phosphate pretreatment (12μm), electrophoretic primer (20μm), epoxy-polyester powder coating (90μm), and clear passivation layer—passing 2000-hour salt spray testing (ASTM B117) with no red rust, suitable for coastal and snowy regions. The steel structure maintains integrity at extreme temperatures from -40℃ (northeast China winters) to 120℃ (engine bay heat radiation), passing 500 thermal cycles (-30℃ to 100℃) without coating peeling. It also resists vibration (500,000 cycles, 5-2000Hz, ISO 16750-3) and mechanical abrasion, ensuring a service life of ≥8 years/400,000km—matching the battery pack’s lifespan

Optimized for efficient NEV fleet maintenance, the bracket combines precision positioning with user-friendly installation. Four conical locating pins (diameter 20mm, length 30mm) fit into the chassis’s pre-drilled holes, ensuring initial positioning accuracy within ±0.5mm. Slotted adjustment holes (20mm×12mm) allow ±6mm micro-adjustment, accommodating minor chassis deformation or battery dimensional variations. The package includes 16 M12×50 grade 10.9 high-strength bolts, lock washers, and flat washers—matching OE torque requirements (180-200N·m). Installation requires only a hydraulic torque wrench; two technicians can complete the process in 50 minutes or less. Clear labeling (“LEFT FRONT” and “BATTERY SIDE”) and part number engraving prevent reverse installation, while the modular design allows easy replacement of damaged guardrails without removing the entire bracket
