Dongfeng KR truck parts Accelerator pedal assembly 1108010-C5100

At the core of the assembly is a hall-effect throttle position sensor (TPS) that delivers accurate, real-time signal feedback to the ECU. The sensor features a 0.1° resolution, translating pedal movement (0–35° rotation range) into precise throttle opening commands—ensuring smooth, linear acceleration without lag or surging. It operates within a 5V signal range (compatible with Dongfeng KR’s ECU) and maintains signal stability even in high-vibration environments (10–2,000 Hz), reducing fuel consumption fluctuations by 3–5% compared to low-precision sensors. Unlike potentiometer-based sensors that wear out over time, this hall-effect design has no mechanical contact points, enduring 1 million+ pedal cycles (equivalent to 5 years of heavy use) without signal degradation—critical for consistent engine performance during long hauls

Built to withstand the rigors of commercial truck operation, the assembly uses rugged materials for long-term durability. The pedal arm is made of 3mm-thick cold-rolled steel (Q235 grade) with a powder-coated finish, resisting bending under 500N of pressure (well above average foot force) and corrosion from moisture or road salt. The pedal pad is crafted from oil-resistant rubber (70 Shore A hardness) with a non-slip textured surface, ensuring secure foot grip even when wet or covered in grease. The pivot joint features a stainless steel bushing (304 grade) that reduces friction, allowing smooth pedal movement for 800,000+ cycles without squeaking or seizing. Unlike plastic pedal arms that crack or rubber pads that peel, this heavy-duty design maintains functionality for 6+ years

Engineered with safety as a priority, the assembly includes multiple safeguards to avoid throttle-related hazards. It has a built-in over-travel stop (limiting pedal rotation to 35°) that prevents TPS damage from excessive force, and a redundant TPS signal (dual-output design) that provides a backup signal to the ECU—ensuring the engine receives accurate throttle commands even if one signal fails. The electrical connector is sealed to IP67 standards, blocking dust and moisture from entering the TPS circuit and causing short circuits. Additionally, the pedal arm’s steel construction is designed to deform (rather than break) in extreme impacts, preventing the pedal from jamming in an open position. These features meet ISO 15031-6 safety standards, eliminating risks of unintended acceleration or throttle failure

Designed for hassle-free replacement by fleet technicians or DIY owners, the assembly simplifies installation and setup. It includes all necessary hardware: 4 OEM-matched bolts (M6×20mm), lock washers, and a foam gasket that reduces vibration transfer to the cab floor. Installation takes 20–25 minutes: align the assembly with the cab’s mounting holes, secure the bolts to 25 N·m torque, and plug the TPS connector into the ECU harness. Unlike aftermarket pedals that require manual TPS calibration, this OEM assembly is pre-calibrated at the factory—no additional programming or tools are needed; the ECU automatically recognizes the pedal and adjusts to its signal range. For maintenance, the rubber pedal pad is removable (via clips) for easy cleaning or replacement, and the TPS requires no periodic servicing. Each unit undergoes strict testing: TPS signal accuracy checks, vibration testing (15G acceleration), and impact resistance trials, backed by a 24-month warranty against defects (e.g., sensor failure, pedal arm bending, pad peeling)
