Dongfeng Xinjiang truck parts Pedal and bracket assembly process 5301910-C35GY17

Built to withstand the repeated mechanical stress of truck pedal operation—including foot pressure (up to 300N for brake pedal) and vibration—the assembly features a reinforced steel-aluminum composite structure. The main bracket is made of Q235 carbon steel (5mm thick) with a tensile strength of ≥375MPa, ensuring it resists bending or deformation even under emergency braking forces. The pedal arm uses 6061-T6 aluminum alloy (4mm thick) for weight reduction (total assembly weight: 2.8kg) without compromising strength, reducing driver fatigue during long-haul use. Key connection points (pedal pivot, bracket-to-floor joints) are reinforced with stainless steel bushings (wear-resistant, service life ≥100,000 cycles) that maintain smooth pedal movement. Unlike plastic brackets, this metal structure avoids cracking from temperature changes (-40℃ to 80℃), ensuring reliable control in extreme environments

Designed for driver comfort and control precision, the assembly incorporates ergonomic features tailored to heavy-duty truck use. The pedal surface is covered with anti-slip rubber (2mm thick) with a grid pattern, providing strong friction even when the driver’s shoes are wet or dusty—preventing foot slippage during emergency braking. The pedal angle (15° from horizontal) is optimized to match the natural foot position of drivers (average height 165-190cm), reducing ankle strain during long driving sessions (8+ hours). The brake pedal’s stroke ratio (1:3.5) is calibrated to balance sensitivity and control, ensuring the driver can apply precise braking force without excessive effort. Additionally, the clutch pedal (if included) features a return spring with adjustable tension, allowing customization based on driver preference—enhancing overall operation comfort

Engineered to endure the daily wear and environmental factors of truck cabs—including dust, spilled liquids, and temperature fluctuations—the assembly features comprehensive protective treatments. The steel bracket undergoes a zinc plating process (8μm thickness) followed by a powder coating (60μm) that resists rust, oil, and chemical cleaning agents. This coating system passes 500-hour salt spray testing (per ASTM B117) with no red rust, ensuring durability in humid or coastal areas. The aluminum pedal arm is anodized (10μm) to prevent oxidation and scratching, maintaining its appearance for over 5 years. The stainless steel bushings are lubricated with high-temperature grease (operating range -40℃ to 180℃), reducing friction and wear during pedal movement. All plastic components (e.g., pedal covers) are made of flame-retardant ABS (UL94 V-0), avoiding melting or deformation from cab heat

Designed for efficient installation, the assembly comes pre-assembled with all necessary components—pedals, bracket, pivot bushings, return springs, and mounting hardware (6 M8×25 bolts, lock washers). The bracket’s mounting holes are pre-threaded to match the cab floor’s pre-drilled holes, eliminating the need for tapping tools. Installation steps are straightforward: align the assembly with the cab floor’s mounting points, secure with the included bolts (torque to 25-30N·m), and connect the pedal rods to the master cylinder (if applicable). No specialized adjustments are required, as the pedal stroke and angle are pre-calibrated at the factory. A professional technician can complete installation in 40 minutes or less, avoiding time-consuming modifications to the cab floor or control system. This quick installation design reduces labor costs and minimizes truck downtime for commercial operators
