Innovative technologies for electric drive shafts of cleaning vehicles
Introduction
Against the backdrop of increasing environmental awareness and growing demand for efficient cleaning solutions, cleaning vehicles, as an important tool for urban environmental maintenance, have attracted much attention for their technological development. As a core component of the power system of cleaning vehicles, the application of innovative technologies of electric drive shafts (Electric Transaxle) is of great significance for improving the performance, efficiency and environmental friendliness of cleaning vehicles. This article will explore in depth the innovative technologies of electric drive shafts for cleaning vehicles and show how these technologies promote the development of the cleaning vehicle industry.

Innovative technologies for electric drive shafts of cleaning vehicles

Automated production and grinding technology
Nantong Saijiayi Precision Technology Co., Ltd. has obtained a patent called “Automated production line station equipment for production and assembly of drive shafts for new energy vehicles”. This patent realizes the fixing and automatic grinding functions of the drive shaft through the synergy of components such as hydraulic rods, movable columns, first pressure plates, fixed columns, second pressure plates and first motors. This innovation not only improves production efficiency and reduces labor costs, but also ensures the processing quality and consistency of the drive shaft, providing a more efficient and precise production method for the manufacture of electric drive shafts for cleaning vehicles.

Efficient cleaning and no-dead-angle design
In the application of cleaning vehicles, the patent “A multi-station cleaning device” obtained by Huiyan Automation Technology (Guangzhou) Co., Ltd. demonstrates an innovative cleaning technology. The patent drives the transmission shaft to rotate through a motor, and uses a right-angle magnetic wheel to drive the brush shaft, realizing efficient linkage between the transmission shaft and the brush. This design enables the cleaning device to clean all parts of the cleaning vehicle without dead angles under the drive of the transmission shaft, and the motion mechanism is more compact, with low noise and no mechanical wear, which extends the service life and reduces maintenance costs.

Hot-pressing connection technology improves transmission stability
The patent “A rear transmission shaft of an electric vehicle and its processing device and processing method” applied by Xuzhou Longfeng Intelligent Technology Co., Ltd. introduces a technology of hot-pressing the transmission half-shaft body and the half-shaft disc by heating the transmission half-shaft body and using a hydraulic cylinder to drive the upper mold and the lower mold to cooperate. This connection method can effectively avoid the slippage between the transmission half-shaft body and the half-shaft disc during high-speed driving of electric vehicles, and ensure the stability and reliability of power transmission. For cleaning vehicles, the application of this technology can improve the power response and handling performance of the vehicle during cleaning operations.

Advanced processing technology enhances torsion resistance
A new energy vehicle drive shaft processing technology significantly improves the torsion resistance of new energy vehicle drive shafts by shrinking the ends of the blanks after cutting to increase the wall thickness, and then undergoing end machining, carburizing shot blasting and surface strengthening shot peening. The drive shaft processed by this process can withstand greater torque loads and will not cause structural damage and breakage at the ends, meeting the needs of new energy vehicles. Cleaning vehicles use this high-torsion electric drive shaft to maintain stable operation in complex cleaning operation environments, improving operating efficiency and safety.

Electric hydraulic continuously variable transmission technology
ZF’s eTERRAMATIC electric drive shaft uses electrohydraulic continuously variable transmission (CVT) technology to provide BEV (battery electric vehicles) and FEV (fuel cell electric vehicles) vehicles with the same driving performance and functions as the traditional TERRAMATIC series. This technology enables cleaning vehicles to achieve smooth power output and speed adjustment according to different cleaning tasks and road conditions, optimize traction and efficiency, and improve driving comfort and operational flexibility.

Electric front axle technology
ZF’s eFAD (electric front axle drive) technology is a variable front-wheel drive system available in low-pressure or high-pressure versions. Compared with rigid all-wheel drive, eFAD technology has significant advantages in optimizing traction and efficiency of the entire drive chain. It can provide cleaning vehicles with the driving comfort of all-wheel drive, reduce fuel consumption, improve traction, and achieve excellent maneuverability through a smaller turning radius, allowing cleaning vehicles to efficiently complete cleaning tasks under various road conditions.

Condition monitoring and predictive maintenance
ZF’s TERRACOM system uses sensors and actuators in the vehicle and drive shaft infrastructure to monitor the behavior and usage of the system to deduce the condition of the system and its components and make predictions or reactions. For cleaning vehicles, this condition monitoring and predictive maintenance technology can reduce vehicle downtime due to failures and damage, provide a knowledge base for future drive system development, simplify the warranty process, improve transparency, and support after-sales service to ensure the long-term stable operation and efficient operation of cleaning vehicles.

Conclusion
The innovative technology of electric drive shafts for cleaning vehicles is constantly driving the cleaning vehicle industry towards a more efficient, environmentally friendly and intelligent direction. From automated production and grinding technology to efficient cleaning and no-dead-angle design, from hot pressing connection technology to advanced processing technology, to electric hydraulic continuously variable transmission technology, electric drive front axle technology and condition monitoring and predictive maintenance, these innovative technologies provide cleaning vehicles with more powerful power support, more stable operating performance and smarter maintenance management. With the continuous advancement and application of technology, cleaning vehicles will be able to play a greater role in urban environmental maintenance and make greater contributions to creating a cleaner and more beautiful urban environment.
