Dongfeng XInjiang truck parts Left lower foot pedal cover bracket assembly 8405349-TCKF01Y

Built to withstand the repeated impact of driver (boarding/alighting) and occasional heavy loads (e.g., drivers carrying tools), the bracket assembly is crafted from Q235 carbon structural steel—an industry standard for automotive load-bearing components. This material delivers a minimum yield strength of 235 MPa, tensile strength of 375–500 MPa, and a maximum static load capacity of 500 kg (exceeding the design requirement of 350 kg for commercial truck pedal brackets). The steel undergoes shot blasting (SA 2.5 grade) to remove surface impurities and enhance material uniformity, ensuring no brittle fracture under repeated stress. Compared to lightweight aluminum brackets, this Q235 steel design improves impact resistance by 40%—critical for withstanding accidental kicks or tool drops during maintenance

Engineered to minimize stress concentration and prevent deformation under dynamic loads, the bracket features a multi-point reinforcement design tailored to high-stress areas:

Pedal Cover Connection Zone: Reinforced with a 8mm-thick steel rib (extending 50mm along the bracket length), increasing local stiffness by 55% and reducing bending by 30% when the pedal is stepped on.

Frame Mounting Zone: Uses a triangular gusset design (weld leg height 6mm) that distributes vertical load to the cab frame, avoiding stress buildup at the mounting holes.

Edge Treatment: All sharp edges are deburred and rounded (radius R3mm) to prevent damage to the pedal cover’s rubber gasket and reduce the risk of injury during maintenance.

Additionally, the bracket’s weld joints (between the main body and reinforcement ribs) are full-penetration welds inspected via visual testing (VT) to ensure no porosity or cracks—critical for withstanding road vibration (10–2000Hz, 15g acceleration) during long-haul transport

Designed to resist corrosion from road salt (used in Xinjiang’s winter de-icing), mud, and moisture—the main causes of bracket premature failure—the assembly undergoes a three-stage protective process:

Zinc Phosphate Coating (60μm): Forms a crystalline base layer that improves adhesion of subsequent coatings and provides initial corrosion resistance.

Electrophoretic Primer (80μm): Seals micro-pores in the steel surface, preventing moisture intrusion and electrochemical corrosion.

Polyester Powder Coating (70μm): Baked at 180–200°C to form a hard, scratch-resistant finish that resists chipping, chemical damage (e.g., diesel, engine oil), and UV degradation.

This coating system passes 1,200 hours of neutral salt spray testing without rust or peeling, ensuring durability in Xinjiang’s harsh climates—from snowy winters (temperatures as low as -35°C) to humid summer grasslands

Designed for efficient replacement by fleet technicians, the bracket simplifies installation with user-friendly details:

Mounting Holes: All holes are drilled to H9 tolerance (precision ±0.04mm) and tapped with standard M10/M12 threads, ensuring perfect alignment with the cab frame’s bolts and pedal cover’s screws—avoiding cross-threading during assembly.

Positioning Marks: Laser-etched reference lines on the bracket align with the cab frame’s mounting points, eliminating the need for time-consuming measurement and ensuring accurate installation.

Hardware Included: The package includes 4 grade 8.8 high-strength bolts (M10×30mm for pedal cover, M12×40mm for frame) and lock nuts (pre-lubricated with anti-seize compound to prevent rust-induced seizing).

Installation takes 30–40 minutes: remove the old bracket by detaching pedal cover and frame bolts, clean the mounting surfaces, align the new bracket’s reference marks, torque the bolts to OEM specs (35 N·m for M10, 60 N·m for M12), and verify pedal cover stability. Each unit undergoes dimensional inspection via CMM, load testing, and coating adhesion checks, backed by a 36-month warranty against defects (e.g., cracking, deformation, coating peeling)
