If your vehicle reaches only 35 km/h while customers expect 50 km/h, the drivetrain may need a better-matched differential. Vibration, gear noise above 4,000 rpm, and weak acceleration can also lead to complaints and returns.
The Avetlink AK differential is intended for higher-power electric tricycles and four-wheelers. Its reinforced spiral-bevel gears and oversized tapered roller bearings are designed to support smooth power transmission at higher speeds.
Actual vehicle speed depends on the complete drivetrain, including the motor, gear ratio, tire size, and vehicle load.

Practical Design Benefits
- Smoother gear engagement: Spiral-bevel gears and specified gear precision help control vibration and noise.
- High-speed bearing support: Oversized tapered roller bearings support the loads associated with higher-speed operation.
- Stronger housing: External ribs reinforce the aluminum housing.
- Matched performance: Gear ratios can be selected to balance acceleration, climbing torque, and top speed.
Customization Options to Discuss with Avetlink
The supplied material lists:
- Gear-ratio selection for target speeds of 40, 50, or 60 km/h, based on motor speed characteristics and tire diameter.
- Drive-system configurations from 48V to 96V.
- Passive cooling fins, forced-air cooling, or a liquid-cooled jacket, depending on duty requirements.
- Gear ratios from 1:8 to 1:16.
- Custom housing colors or a bare-aluminum finish.
- Matched programmable controllers with selected speed–torque settings.
- 3D modeling and prototype validation within two weeks, subject to project confirmation.
- An OEM minimum order of 100 units per model.
Avetlink AK Differential Options for Electric Utility Vehicles
Electric utility vehicles used in residential communities and resorts need a drivetrain that matches their load, target speed, and daily operating conditions.
When selecting an Avetlink AK differential, consider the complete drivetrain. The motor, controller, gear ratio, tire diameter, and vehicle weight all affect acceleration and top speed.
Reviewing these details together helps identify a suitable configuration before making changes to an existing vehicle or starting a new production project.
Evaluate a Prototype Before Production
A prototype allows you to check installation and performance in the intended vehicle.
The evaluation should cover:
- Mechanical fit: Mounting points, shaft connections, alignment, and available space.
- Driving performance: Starting, acceleration, and top speed under the intended load.
- Noise and vibration: Measurements under clearly recorded, consistent operating conditions.
- Temperature: Performance during the expected operating cycle and sustained use.
Compare noise results at the same speed, load, and measurement position. Readings taken under different conditions do not establish a direct noise reduction.
Frequently Asked Questions
Q1: What configuration should I consider for a target speed of 50 km/h?
A 72V, 3,000W brushless DC motor with a matched vector controller can be discussed as a starting configuration. It does not guarantee a vehicle speed of 50 km/h.
The suitable gear ratio depends on motor speed and torque, tire rolling diameter, vehicle weight, and operating load. Send these details to Avetlink to discuss an AK configuration and a vehicle test plan.
Q2: Does higher-speed operation affect service life?
Service life depends on speed, load, lubrication, cooling, and maintenance.
Confirm the operating limits and maintenance requirements for the selected AK configuration. If sustained higher-speed operation is required, discuss whether additional cooling is needed and validate the arrangement in the vehicle.
Q3: Is a retrofit package available?
Contact Avetlink to discuss whether an AK differential, compatible controller, and mounting adapters can be supplied for your vehicle.
Confirm the package contents and installation requirements before ordering. A prototype evaluation can help identify fitment or performance changes before a bulk purchase.
