Practical Protection Features
- Triple-lip sealing: Helps limit water and dust entry around rotating shafts.
- Corrosion-resistant construction: Coated gears and housing help protect exposed surfaces.
- Pressure equalization: The membrane breather reduces pressure changes that can place stress on seals.
- Application matching: Gear ratios, connectors, and mounting dimensions can be selected for the vehicle’s operating needs.
Customization Options to Discuss with Avetlink
The original description lists:
- An IP68 option, with immersion depth and duration to be agreed for the application.
- Drive-system configurations from 24V to 72V.
- Gear-ratio selection for 5–15 km/h sweeping work or 20–30 km/h transport.
- Safety yellow, municipal green, or a specified RAL color.
- Sealed Deutsch, Amphenol, or customer-specified connectors.
- A membrane breather or fully sealed configuration, depending on operating conditions.
- 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 Street Sweepers
Electric street sweepers work in rain, dust, and wet road conditions. Water entering the differential can damage bearings and lead to repairs and vehicle downtime.
Selecting a suitable Avetlink AK differential configuration starts with understanding the vehicle’s operating environment, load, mounting arrangement, and cleaning routine.
The housing, shaft seals, and sealing materials should match these requirements to support reliable daily operation.
Confirm Protection and Cleaning Requirements
Request protection-test documents for the specific AK configuration being considered. Check that the report covers the supplied assembly and clearly states the test conditions.
A production leak check, water-spray test, and immersion test assess different conditions. They should not be treated as interchangeable proof of protection.
Cleaning requirements should also be confirmed separately, including water pressure, temperature, spray distance, and detergent compatibility.
Frequently Asked Questions
Q1: What is the difference between IP54 and IP67?
IP54 provides protection against limited dust entry and water splashes.
IP67 indicates dust-tight protection and temporary immersion protection under specified test conditions.
An IP67 rating does not automatically establish suitability for high-pressure or hot-water washing. Confirm the rating and cleaning limits for the selected AK assembly.

Q2: Can the vehicle be pressure-washed every day?
This depends on the differential’s approved cleaning conditions. Confirm the permitted water pressure, temperature, spray distance, cleaning products, and washing frequency before use.
Seal materials must be compatible with the actual operating environment and cleaning chemicals. Discuss suitable material options with Avetlink when selecting the configuration.

Q3: Can an AK differential fit an existing street sweeper?
Provide drawings, measurements, or a sample showing:
- Mounting bolt pattern.
- Shaft lengths, diameters, and connection types.
- Available installation space.
- Positions of nearby components and any associated electrical connections.
These details help determine whether a suitable AK configuration or mounting adaptation is possible. Confirm development costs, prototype requirements, and fitment validation before ordering.
