S21-3550111 Wheel Speed Sensor for Chery QQ

Product Introduction

S21-3550111 Wheel Speed Sensor for Chery QQ

Our OEM-grade wheel speed sensors monitor real-time rotational velocity of each wheel with ±0.5% accuracy. Utilizing Hall-effect or magnetoresistive technology, they transmit critical data to ECU for:

● Anti-lock Braking (ABS) modulation

● Traction Control System (TCS) intervention

● Electronic Stability Program (ESP) calibration

● Encased in IP6K9K-rated stainless steel housing, these sensors withstand road debris, -40°C to 150°C temperatures, and high-pressure washdowns.

Product Uses

Here are specific application scenarios of Wheel Speed Sensor:

1. Emergency braking on icy and slippery road surfaces

When the vehicle is suddenly braked on a snow covered road or a rainstorm slippery road, our sensors monitor the speed difference of four wheels in real time with a response speed of 0.15 ms, triggering the ABS system to brake 15-20 times per second to prevent the tires from locking and slipping. Actual test data: The braking distance is reduced by 2.1 meters at a speed of 80 km/h, reducing the risk of side slip accidents by 63%.

2. Prevent loss of control in rough terrain during off-road driving

Suitable for mountain off-road vehicles and construction vehicles, when the wheels are suspended on gravel/muddy roads, the sensor cooperates with the ESC system to lock the idler wheel within 0.2 seconds and distribute torque to the traction tires. The IP68 protective shell resists erosion from mud and water, and maintains 99.3% signal stability even in extremely cold environments of -40 ° C.

3. Stability control of high-speed curved vehicles

When the vehicle is turning at a high speed of 150km/h, the real-time detection of the speed difference between the inner and outer wheels is used, and the ESC system automatically adjusts the single wheel braking force to offset the risk of rollover caused by centrifugal force. Triple electromagnetic shielding technology ensures zero signal loss at a speed of 250km/h.

4. Intelligent maintenance management of commercial vehicle fleets

Provide predictive maintenance for logistics trucks and rental fleets: sensors with built-in AI chips diagnose the health of the lines every 10 seconds and warn of wear and tear risks 7 days in advance. Compatible with Telematic system to automatically generate maintenance work orders, reducing accidental downtime losses by 35%.

5. Optimization of energy recovery for new energy vehicles

When the electric vehicle releases the throttle and slides, the precise monitoring of wheel speed changes and coordinated regenerative braking system can improve the efficiency of recovering kinetic energy by 18%. Anti motor interference design avoids signal distortion and ensures a range error of less than 0.5%.

Product Operate Guide

1. Precise matching of vehicle models (completed in 30 seconds)

Operation: Visit the website 'Vehicle Model Query Tool', enter the brand/year/model (such as' 2019 Toyota RAV4 '), and the system will automatically push the exclusive part number.

Error prevention prompt: Check the wheel hub size (16 "or 18") and drive mode (front wheel drive/four-wheel drive) to avoid accidental purchase.

2. 3-minute quick installation

Steps:

① Disconnect the negative terminal of the battery (necessary for safety) → ② Lift up the vehicle and remove the wheels → ③ Remove the old sensor plug (do not forcefully pull the buckle) → ④ Install the new sensor (lock it when you hear a "click" sound) → ⑤ Restore the tire and reconnect it to the battery.

Data endorsement: The average installation time measured by American users is 3 minutes and 17 seconds.

3. Fault self inspection verification

Operation: After starting the vehicle, if the ABS light on the dashboard goes out within 10 seconds, the installation is successful. If it is constantly on:

Read the fault code (P0500=signal loss) using an OBD-II scanner

Check if the plug is fully inserted (90% of the faults are caused by this)

Support: The official website provides a fault code solution library (covering 127 types of errors).

4. Suggestions for Extreme Environment Testing

Verification method:

① High pressure water gun for car washing, directly targeting the sensor area (IP68 waterproof verification)

② After being refrigerated at -20 ° C for 30 minutes, load the vehicle and test the signal on icy and snowy roads

Data feedback: The warranty for participating users has been extended to 48 months.
