Electric Drive Shafts For Medium scrubber machine and Electric trolley

An electric transaxle is an integrated drive system typically positioned at the end of the powertrain. It comprises components such as a DC motor, a reduction gear assembly (including the main reduction gear and differential), half-shafts, and a housing. Its core function is to alter the direction of torque transmission, reduce rotational speed, and increase torque through gear pairs. Simultaneously, it enables differential rotation of the wheels on both sides, ensuring smooth operation of the vehicle or equipment during turns.

This product features a durable aluminum alloy or steel housing, alloy steel hardened gears, and a high-efficiency DC motor. It is primarily used in medium-sized electric equipment such as light three-wheeled electric motorcycles, medium-sized floor scrubbers, and electric hand trucks. It is particularly suitable for scenarios including urban short-distance freight transport, community delivery, mobility vehicles for the elderly/disabled, and rural light-duty transportation.

The core features of this electric drive axle lie in its robust power output and optimized performance parameters. With rated power options of 400W, 500W, and 800W, and a maximum load capacity of 300KG, it delivers sufficient load-bearing capability and supports operation on surfaces with gradients ≤10°. Output speed is controlled between 170-285 RPM, making it suitable for complex road conditions such as cargo uphill climbs, unpaved surfaces, and speed bumps. The reduction ratio is approximately 20:1, utilizing planetary gears or worm gear structures to achieve efficient torque conversion with transmission efficiency exceeding 85%. Electrically, the load current ranges from 13A to 56A. It incorporates overload protection circuits and thermistor monitoring, automatically shutting down or triggering an alarm when temperatures exceed 80°C to ensure safe operation.

Additionally, an optional electromagnetic brake with a response time under 0.5 seconds further enhances braking performance. These specifications enable smooth acceleration and efficient energy consumption control even at full load (300kg), supporting 4-6 hours of continuous operation.

In structural design, this product features an aluminum alloy or steel housing with rust-proof surface treatment. The core gears utilize hardened alloy steel materials, combined with precision machining and specialized lubricants to significantly reduce wear and vibration. The unit boasts an IP54 protection rating (IP65 optional), effectively resisting dust, rain spray, and mud ingress. It adapts to complex environments including urban and rural roads, marketplaces, construction site peripheries, and rainy season operations. Its modular design supports optional additions such as encoders, speed limiters, and reverse functions, meeting diverse regional regulations and customer requirements.

Noise control is a major highlight of this product, with operating noise levels as low as ≤54-65 dB—significantly lower than traditional mechanical equipment. Utilizing low-noise motors and gear lubrication technology, it is particularly suitable for noise-sensitive environments such as hospitals or nursing homes. In terms of environmental protection, this drive axle achieves zero emissions, eliminating exhaust fumes or oil contamination, and meets green clean standards.

This electric drive axle is specifically engineered for high-intensity, multi-scenario, and all-weather operational environments. Its structural protection, material selection, and thermal management mechanisms are all deeply optimized for real-world conditions, ensuring consistent and stable power delivery under various demanding conditions.

In the operating conditions of medium-sized floor scrubbers and industrial cleaning equipment, drive axles are continuously exposed to environments characterized by high humidity, water exposure, chemical cleaner splashes, and friction from ground oil and grit. Work areas are often enclosed and high-temperature environments (such as shopping mall atriums or factory workshops). Additionally, the equipment requires prolonged low-speed operation, frequent starts and stops, and on-the-spot turning. This places extremely high demands on motor heat dissipation and sealing integrity.

For electric pallet trucks and logistics transfer platforms, equipment is primarily deployed in warehousing centers, wholesale markets, fresh produce distribution stations, and airport cargo yards. Common ground contaminants include metal shavings, packaging debris, oil stains, and meltwater, with high ambient dust concentrations. Equipment must operate continuously for 4 to 8 hours per shift, enduring frequent acceleration/deceleration and heavy-load starts/stops (300kg cargo boxes, racks, or equipment). This poses severe challenges to the drive system's shock resistance, wear resistance, and sustained load capacity.

In the operating environment of light tricycles (cargo/passenger models), this drive shaft is particularly suited for non-standard road conditions such as areas surrounding vegetable markets, construction sites, farm fields, and coastal villages. It withstands prolonged exposure to sun and rain, mud splashes, and salt spray corrosion (in coastal regions).
