Dongfeng VR truck parts electronic throttle Accelerator pedal assembly 1108010-C1100

Equipped with a non-contact Hall-effect sensor (instead of traditional potentiometers), the assembly delivers accurate throttle input with 0.1° resolution—translating driver foot movement into precise fuel injection adjustments. The sensor operates on a 5V reference voltage, outputting a linear 0.5–4.5V signal that correlates to pedal position (0–100% travel). This electronic design eliminates mechanical wear from contact points, ensuring consistent performance even after 2 million actuations (equivalent to 10 years of heavy use). Testing confirms response time of ≤50ms between pedal movement and engine reaction, providing smooth acceleration transitions critical for heavy-duty hauling

Built to withstand constant foot pressure, vibration, and cab contaminants, the assembly features a reinforced nylon 66 pedal arm (glass fiber reinforced, 30% by weight) with a tensile strength of 85 MPa—resisting bending or cracking under 150N of force (typical driver input). The base housing is made of impact-resistant PBT plastic, rated to -40°C to 85°C operating temperature to handle extreme cabin conditions. A stainless steel return spring (304 grade) ensures reliable pedal reset, maintaining tension even after 1 million cycles. The waterproof connector (IP6K9K rated) prevents moisture and dust intrusion, critical for withstanding cab cleaning or condensation

Integrated safety mechanisms prevent throttle malfunctions: dual independent Hall-effect sensors provide redundant position signals, with the ECU cross-checking both inputs to detect anomalies (e.g., short circuits, signal drift). If a discrepancy is detected, the system defaults to a limp-home mode (limited to 1500 RPM) to prevent uncontrolled acceleration. The pedal also includes an overtravel stop (mechanical limit at 105% travel) to protect internal components from excessive force. These features comply with ECE R13H safety standards, ensuring fail-safe operation in critical scenarios

Designed for quick replacement by technicians, the assembly requires no calibration tools—simply disconnect the old pedal’s electrical connector, unbolt the 4 mounting screws (M6×16mm), and secure the new unit with the included hardware. A pre-applied dielectric grease seal on the connector ensures weatherproofing upon reconnection. Maintenance is minimal: the sealed sensor housing is (no lubrication needed), and the pedal surface features a textured rubber grip that resists wear and provides non-slip operation even with wet boots. Each unit undergoes signal linearity testing, vibration endurance checks, and environmental sealing verification, backed by a 24-month warranty against defects (e.g., sensor failure, housing cracks, spring fatigue)
