Designed for Quiet Sightseeing and Passenger Transport
The Avetlink AK differential is designed for compatible passenger electric tricycles used on sightseeing routes and in shuttle services.
Its helical gears and precision-lapped contact surfaces help reduce gear noise and support smooth power transmission. Quieter operation can improve comfort for passengers and drivers, especially on residential streets, scenic routes, and waterfront roads.
Different vehicles have different requirements. Selecting the right gear ratio and installation dimensions helps match the AK differential to your motor, vehicle load, and operating speed.
Evaluate Performance in Your Vehicle
Actual noise levels depend on the complete drivetrain, including the motor, controller, mounting, and operating conditions.
Testing a sample in your vehicle helps assess:
- Noise: How the drivetrain sounds during starting, acceleration, and steady driving.
- Smoothness: How the vehicle performs under its intended passenger load.
- Compatibility: Whether the mounting points, shafts, and drivetrain components fit correctly.
- Application suitability: Whether the configuration meets your route and operating requirements.
Use consistent measurement conditions when comparing noise levels. A no-load check and a full-load test measure different operating conditions and should be assessed separately.
Frequently Asked Questions
Q1: How can I confirm the AK differential’s noise performance?
Request noise-test information for the specific AK configuration you are considering. The information should identify the measurement distance, operating speed, load, and test conditions.
Evaluate a sample in the complete vehicle before placing a bulk order. If third-party testing is required, confirm the testing arrangements and costs with Avetlink.

Q2: Will it work with my existing motor and controller?
The AK differential can be matched with suitable 48V, 60V, or 72V brushless DC drive systems, including systems using compatible sine-wave or vector controllers.
Final selection depends on mechanical fit, motor torque and speed, gear ratio, and controller matching. Send your motor specifications and installation dimensions to Avetlink for configuration review.

Q3: Can I order a branded version in a custom color?
Discuss options such as laser-marked logos, custom RAL housing colors, and branded packaging with Avetlink. Available finishes, minimum order quantities, pricing, and lead times should be confirmed for your selected configuration.
A sample can help you check fit, appearance, and operating noise before a larger order.
