Dongfeng Xinjiang truck Right lower foot pedal cover bracket assembly 8405350-TCKF01Y

Crafted from Q235 carbon structural steel—an industry standard for automotive load-bearing components—the bracket delivers exceptional mechanical performance to withstand daily  (boarding) and occasional heavy loads (e.g., drivers carrying toolboxes). The material exhibits a minimum yield strength of 235 MPa, tensile strength of 375–500 MPa, and a static load capacity of 550 kg (exceeding the design requirement of 400 kg for commercial truck pedal brackets). The steel undergoes shot blasting (SA 2.5 grade) to remove surface rust and impurities, followed by stress relief annealing at 650°C to eliminate internal stress from manufacturing—preventing deformation or cracking under cyclic loads (average 15–20 cycles per day). Compared to lightweight aluminum brackets, Q235 steel improves impact resistance by 45%, making it suitable for rough-use scenarios like construction site transport

Designed to resist corrosion from Xinjiang’s extreme environmental conditions—road salt in winter, sandstorms in spring, and humidity in summer—the bracket undergoes a three-stage protective process:

Zinc Phosphate Coating (60μm): Forms a crystalline base layer that enhances adhesion of subsequent coatings and provides initial protection against electrochemical corrosion.

Electrophoretic Primer (80μm): Seals micro-pores in the steel surface, blocking moisture and dust intrusion (critical for preventing rust in - prone areas).

Polyester Powder Coating (70μm): Baked at 180–200°C to create a scratch-resistant finish (Mohs hardness ≥5H) that resists diesel stains, road salt, and UV degradation—passing 1,200 hours of neutral salt spray testing without rust.

This coating system ensures the bracket maintains structural integrity for 6+ years, even in Xinjiang’s temperature extremes (from -35°C in winter to 45°C in summer)

To address common failure points in pedal brackets (e.g., stress cracks at mounting holes, bending at pedal connection), the assembly features targeted reinforcement:

Mounting Hole Reinforcement: Each of the 4 mounting holes (10mm diameter) is reinforced with a 3mm-thick steel sleeve, increasing local stiffness by 60% and preventing hole deformation from repeated bolt tightening.

Pedal Connection Zone: A triangular gusset (6mm-thick steel) welded between the bracket main body and pedal cover mounting plate, distributing force to the cab frame and reducing bending by 35%.

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

The bracket also passes 10–2000Hz vibration testing (15g acceleration)—simulating rough road conditions in Xinjiang’s rural areas—without component loosening or weld failure

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

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

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 reducing installation time by 40%.

Included Hardware: The package comes with 4 grade 8.8 high-strength bolts (M10×35mm) and lock nuts (pre-coated with anti-seize compound to prevent rust-induced seizing), compatible with standard 13mm sockets.

Installation takes 25–35 minutes: remove the old bracket by detaching pedal cover and frame bolts, clean the mounting surface, align the new bracket’s reference marks, torque bolts to 35 N·m (for M10), and verify pedal 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)
