810W27120-6183 ABS Sensor Replacement Truck Accessories

810W27120-6183, ABS Sensor

The ABS Sensor 810W27120-6183 is a specific right-rear wheel speed sensor designed for heavy-duty trucks, primarily compatible with models such as Sinotruk Howo T7H, T5G, and SITRAK C7/C9. As a core component of the Anti-lock Braking System, this sensor plays a vital role in vehicle safety.

Function

Wheel Speed Monitoring & Signal Transmission

The ABS Sensor 810W27120-6183 interacts with a tone ring that rotates synchronously with the wheel, producing a quasi-sinusoidal AC signal. The frequency and amplitude of this signal are directly related to the wheel speed. This signal is transmitted to the ABS Electronic Control Unit for real-time wheel speed monitoring.

Anti-lock Braking Control

During braking, the sensor accurately detects the speed of each wheel and quickly determines if a wheel is about to lock up. Upon detecting imminent lock-up, the ABS control module modulates the brake pressure to that wheel via solenoid valves, preventing complete lock-up and creating a cyclic "lock-release" action.

Main Purpose

Vehicle Safety Assurance

The sensor is primarily used to ensure directional stability and controllability during emergency braking. By preventing wheel lock-up, it helps avoid loss of control scenarios like skidding or jackknifing, significantly enhancing driving safety.

Electronic Stability System Support

As a key part of modern electronic stability systems, it provides essential wheel speed data for functions like Traction Control and Electronic Stability Control, ensuring optimal vehicle handling under various road conditions.

Braking System Performance Optimization

By monitoring wheel speed in real-time, it enables the braking system to precisely control brake force, keeping wheel slip at an optimal level to maximize tire-road adhesion for the shortest possible stopping distance.
