Product Introduction

This precision gear ring is a critical safety component of the ABS system, designed to generate a speed signal for the ABS controller by interacting with the magnetic wheel speed sensor, helping prevent wheel lock during braking.

Structure & Material

• Material: High-strength spring steel, with a zinc-plated (rainbow passivated) finish for corrosion resistance.

• Design: A toothed ring with evenly spaced external teeth, mounted to the wheel hub or axle shaft. The teeth create a changing magnetic field as they pass the sensor, generating an electrical speed signal.

Performance

• Speed Detection: The toothed design creates a precise speed signal for the ABS controller, enabling real-time wheel speed monitoring.

• Anti-Lock Braking Support: Allows the ABS system to adjust brake pressure dynamically, preventing wheel lock and maintaining steering control.

• High Precision: Uniform tooth spacing ensures accurate speed measurement even at high rotation speeds.

Durability

• Spring steel construction resists deformation under vibration and wheel-end loads.

• Rainbow zinc plating withstands harsh environmental conditions, including moisture and road debris.

Core Function

1. Speed Signal Generation: Produces a wheel speed signal for the ABS controller.

2. ABS System Support: Enables anti-lock braking functionality to maintain vehicle stability.

3. Safety Enhancement: Reduces the risk of skidding during emergency braking.

ABS Gear Ring AZ711734009002 – Sinotruk Sitrak Heavy-Duty Truck Parts

When your braking system demands precision, the ABS Gear Ring AZ711734009002 delivers exactly that. Engineered specifically for Sinotruk Sitrak heavy-duty trucks, this critical rear axle component works hand-in-hand with the ABS sensor to monitor wheel speed in real time — ensuring your anti-lock braking system performs flawlessly under every road condition. At Mettlead, we supply this genuine-spec gear ring at factory-direct pricing, so you get OEM-level quality without the inflated cost.

Why This ABS Gear Ring Matters for Your Fleet

The ABS gear ring isn’t just another metal component sitting quietly on the axle. It’s the heartbeat of your braking safety system. Without a properly functioning gear ring, the ABS sensor can’t accurately read wheel rotation speed, which means your entire anti-lock braking system goes blind. Here’s what makes this particular part stand out:

• Precision-Machined Tooth Profile – Each tooth is carefully machined to maintain consistent spacing, allowing the ABS sensor to generate clean, reliable signals even at high speeds.
• High-Grade Steel Construction – Built from hardened alloy steel that resists wear, corrosion, and thermal deformation over hundreds of thousands of kilometers.
• Direct-Fit Replacement – Designed as a drop-in replacement for OEM part number AZ711734009002, so installation is straightforward with no modifications needed.
• Braking Safety Assurance – By delivering accurate speed data to the ECU, this gear ring helps prevent wheel lock-up during emergency braking, protecting both driver and cargo.
• Extended Service Life – Strict quality control during manufacturing ensures this ring won’t fail prematurely, reducing unplanned downtime for your fleet.

Application Scenario: Where This ABS Gear Ring Works

This ABS Gear Ring AZ711734009002 is specifically designed to fit Sinotruk Sitrak series heavy-duty trucks. Mounted on the rear axle hub assembly, it cooperates seamlessly with the wheel speed sensor to continuously monitor rotational velocity. As the wheel turns, the sensor reads the passing gear teeth and sends pulse signals to the ABS control unit. In other words, this gear ring is the foundation that keeps your entire braking safety system functioning correctly.

Whether your Sitrak trucks are hauling heavy loads across highways or navigating wet mountain roads, this component ensures the ABS system can intervene precisely when wheels begin to lock — maintaining steering control and stopping distance within safe limits.

Frequently Asked Questions – ABS Gear Ring AZ711734009002

What does the ABS gear ring AZ711734009002 actually do?

This ABS gear ring (also called a tone ring or reluctor ring) generates magnetic pulse signals as it rotates with the wheel hub. The ABS sensor reads these pulses to calculate wheel speed. If the system detects that a wheel is decelerating too rapidly — indicating potential lock-up — the ABS module instantly modulates brake pressure to maintain traction and steering control.

How do I know when this ABS gear ring needs replacement?

Common symptoms include an illuminated ABS warning light on the dashboard, erratic ABS activation during normal braking, or diagnostic trouble codes pointing to wheel speed sensor irregularities. Physical inspection may reveal cracked, chipped, or worn teeth on the ring, as well as excessive corrosion that interferes with sensor readings.

Is this gear ring an exact replacement for the original Sitrak part?

Yes. The AZ711734009002 ABS gear ring we supply is manufactured to OEM-equivalent specifications, including tooth count, diameter, and material grade. It installs directly onto the rear axle hub without any modification, just like the factory-original component.

Can a damaged ABS gear ring affect other braking components?

Absolutely. When the gear ring sends inaccurate signals — or no signal at all — the ABS system may deactivate entirely. This means you lose anti-lock protection during hard braking. Additionally, inconsistent signal patterns can confuse the electronic stability program (ESP), potentially triggering unwanted interventions or disabling traction control features.

What’s the typical service life of this ABS gear ring?

Under normal operating conditions, a quality ABS gear ring can last the lifetime of the axle assembly. However, exposure to road debris impacts, heavy corrosion environments (salt, moisture), or improper installation can shorten its service life. Regular inspection during brake maintenance is recommended.
