FIELD OF INVENTION
[1] The present disclosure relates to electric vehicle industrial cleaning equipment, and more particularly to an electric self-propelled hydraulically operated automotive sweeping machine with integrated brushing systems and debris collection capabilities for cleaning various surfaces including roads, streets, and industrial areas.

BACKGROUND OF INVENTION
[2] Industrial cleaning equipment has evolved significantly alongside advances in manufacturing and industrial processes. The variety of machines available spans a wide range of applications, enabling cleaning operations to be carried out efficiently across different environments. Sweeping machines represent a substantial segment of this equipment category, designed to remove dirt, debris, and other contaminants from various surface types including warehouse floors, airport runways, manufacturing facilities, and outdoor areas.
[3] Traditional sweeping machines typically incorporate several standard components including rotating brushes, debris collection systems, and propulsion mechanisms. Conventional automotive sweepers generally feature four-wheel configurations with main brushes positioned behind rear wheels, debris elevating systems, and side brooms for edge cleaning. These machines commonly include vacuum-operated pick-up heads for removing dislodged debris, hoppers for collecting removed materials, and blower units for generating airflow patterns from pick-up heads through collection chambers.
[4] The selection of appropriate sweeping equipment depends on multiple factors including surface type, physical dimensions of the area to be cleaned, and the nature of debris to be removed. Different surface materials and debris characteristics require specific brush configurations, suction capabilities, and collection mechanisms to achieve effective cleaning results.
[5] However, conventional sweeping machines face several operational challenges that limit their effectiveness. Many existing sweepers demonstrate inefficient debris removal, particularly when dealing with relatively heavy materials, resulting in incomplete cleaning of surface areas. The partial removal of debris often requires multiple passes over the same area, reducing operational efficiency and increasing operational costs.
[6] Street sweeping operations present additional difficulties related to surface irregularities and uneven terrain. Operators must navigate vehicles over surfaces that were not designed with sweeping machine operation in mind, requiring equipment to accommodate existing street conditions rather than operating under optimal circumstances. This necessitates design approaches that enable sweeping machines to adapt to uneven and irregular surfaces while maintaining cleaning effectiveness.
[7] Environmental considerations also present challenges for traditional sweeping equipment. Many conventional machines rely on internal combustion engines, contributing to emissions and noise pollution during operation. The environmental impact of cleaning operations has become a growing concern, particularly in urban areas and enclosed industrial facilities where air quality and noise levels affect worker comfort and regulatory compliance.
[8] Current industrial sweeping machines predominantly rely on internal combustion engines that produce significant emissions, noise pollution, and have high operational costs. These conventional sweepers often struggle with efficient debris removal, particularly on irregular surfaces, and lack the integration of hydraulic and electric systems needed for optimal performance. Additionally, existing machines typically have limited adaptability across different cleaning environments and insufficient power management systems, resulting in reduced operational efficiency and increased environmental impact.
[9] There is a critical need for an environmentally friendly, electric-powered sweeping machine that integrates advanced hydraulic systems to enhance cleaning efficiency while reducing emissions and operational costs. This invention addresses the demand for a self-propelled sweeper that can effectively operate across diverse environments with improved debris collection capabilities, optimized power consumption, and reduced environmental footprint. The integration of electric propulsion with hydraulic operation systems offers a solution that meets increasingly stringent environmental regulations while providing superior cleaning performance and operational flexibility for industrial, municipal, and commercial applications.

OBJECT OF INVENTION
[10] A main objective of the present disclosure is to provide an integrated hydraulic-electric system that enables coordinated power management between propulsion and cleaning operations through centralized control systems, thereby optimizing energy distribution based on operational demands while maximizing cleaning performance and maintaining energy efficiency throughout the sweeping cycle.
[11] Another objective of the present disclosure is to provide a hydraulically operated automotive sweeper with a simple configuration that reduces manufacturing costs, minimizes required manpower for operation, and decreases maintenance expenses through integrated electric and hydraulic systems.
[12] Another objective of the present disclosure is to provide an electric vehicle self-propelled hydraulically operated automotive sweeper that can be easily manufactured and operated to deliver comfortable and efficient removal of dust and debris through advanced hydraulic control systems and automated operational capabilities.
[13] Another objective of the present disclosure is to provide a self-propelled hydraulically operated automotive sweeper that enables fast and efficient cleaning applications for roads, streets, and areas while maintaining operator safety and maximizing cleaning effectiveness across diverse surface conditions.
[14] Another objective of the present disclosure is to provide an integrated sweeping system that effectively collects and contains dust and debris within a closed hopper assembly using filtering mechanisms, thereby preventing dispersion of collected materials during operation and improving overall cleaning performance.
[15] Another objective of the present disclosure is to provide an electro-hydraulic brush control system that combines electric motor control with hydraulic positioning mechanisms to enable precise brush pressure adjustment and positioning during sweeping operations. The system integrates electric motors with hydraulic cylinders and control valves to provide responsive brush positioning based on surface conditions and debris density, thereby optimizing cleaning effectiveness while maintaining consistent brush contact pressure across varying terrain conditions.

SUMMARY OF INVENTION
[16] The invention provides an electric vehicle self-propelled sweeping machine with an integrated hydraulic operation system. The sweeper comprises a chassis with front wheels, a steerable rear drive wheel powered by a PMSM electric motor, and a hydraulic system that operates the cleaning mechanisms. Key components include side and main brushes for debris collection, an impeller system directing dust into a hopper, and hydraulic lifting capabilities for waste disposal. The console assembly houses controls for brush positioning and hopper operation. The machine features protective elements including a bumper, back guard, and brush door.
[17] Operation involves activating the electric motors to operate hydraulic system, using side brushes to sweep debris toward the center, rotating the main brush counter to travel direction, and collecting waste via the impeller into the hopper for later disposal. The integration of electric propulsion with hydraulic operation eliminates emissions while providing superior cleaning performance across diverse environments. This configuration optimizes power consumption while offering an effective solution for industrial, municipal, and commercial cleaning applications that meets environmental regulations and reduces operational costs.

Said gear box (36) provides mechanical stability for the drive system components during operation and enables transfer of driving forces from the wheel drive electric motor (34) to the rear drive wheel (17).
[54] The wheel drive electric motor (34) comprises a permanent magnet synchronous motor (PMSM) configuration that provides enhanced torque characteristics for operation on uneven surfaces. The wheel drive electric motor (34) is positioned adjacent to the rear drive wheel (17) and provides direct drive capability to the rear drive wheel (17). The wheel drive electric motor (34) generates rotational force that enables the sweeping machine (9) to traverse irregular terrain and maintain operational capability across varying surface conditions.The rear drive wheel (17) is connected to the wheel drive electric motor (34) to provide propulsion for the sweeping machine (9). The wheel drive electric motor (34) receives electrical power from the electrical system and converts the electrical energy to mechanical rotation for driving the rear drive wheel (17).
[55] A wheel actuator (35) is positioned above the rear drive wheel (17) and is connected to the drive assembly to provide rotational positioning capability. The wheel actuator (35) is controlled by the steering wheel (11) and enables the rear drive wheel (17) to rotate through a 180-degree range of motion. The wheel actuator (35) provides enhanced maneuverability for the sweeping machine (9) by enabling directional changes and positioning adjustments during sweeping operations. The wheel actuator (35) responds to steering inputs from the steering wheel (11) to position the rear drive wheel (17) according to operator directional commands.
[56] The wheel actuator (35) enables the rear drive wheel (17) to rotate 180 degrees relative to the chassis (1) through the steering wheel (11), providing enhanced steering capability and maneuverability for the sweeping machine (9). The 180-degree rotation capability of the rear drive wheel (17) enables the sweeping machine (9) to perform tight turning maneuvers and navigate confined spaces during sweeping operations.
[57] FIG. 7 illustrates a perspective view showing the electrical system configuration and power management arrangement in the EV self-propelled hydraulically operated automotive sweeper machine (9). The electrical system provides coordinated power distribution to all electric components of the sweeping machine (9) and enables integrated operation of the propulsion, hydraulic, and control systems. The hydraulic tank (31) is positioned adjacent to the electrical system components and provides hydraulic fluid storage for the hydraulic system operations.
[58] An electric motor (38) is positioned within the electrical system arrangement and provides power for hydraulic system operations. The electric motor (38) drives hydraulic pumps and control valves that operate the hopper cylinder (10), brush motors, and other hydraulically operated components of the sweeping machine (9). An electric motor (39) is positioned adjacent to the electric motor (38) and provides additional power for auxiliary systems and backup operations of the sweeping machine (9).
[59] A battery (43) supplies electrical power to perform all operations of the sweeping machine (9). The battery (43) is connected with the motor drives (40, 41) through cable (44) that provide regulated power control to motors (38, 39) to adjust the motor speed, torque, and direction based on control signals. The motor drives (40, 41) receive power from the battery (43) and convert the electrical energy to controlled power output for the electric motors (38, 39). Similarly, said battery (43) is connected with the motor drive (42) through cable (44) that provides regulated power control to motor (34) to adjust the motor speed, torque, and direction based on control signals. The motor drive (42) receives power from the battery (43) and converts the electrical energy to controlled power output for the electric motor (34).
[60] The electric motors (38, 39) drive hydraulic pumps and control valves to supply pressurized hydraulic fluid from the hydraulic tank (31) to perform various hydraulic functions throughout the sweeping machine (9). The hydraulic system powered by the electric motors (38, 39) operates the hopper cylinder (10) for lifting operations, brush positioning mechanisms, and debris collection components. The coordinated operation between the battery (43), motor drives (40, 41), and electric motors (38, 39) enables precise control of hydraulic functions based on operator inputs and system requirements.
[61] The cable (44) provides electrical connections between the battery (43) and the motor drives (40, 41), enabling power transmission and control signal communication throughout the electrical system. The motor drives (40, 41) regulate the electrical power supplied to the electric motors (38, 39) and provide variable speed control, torque adjustment, and directional control based on operational demands. The integrated power management system optimizes energy consumption and coordinates the operation of all hydraulic functions to maximize operational efficiency and battery life during sweeping operations.
[62] The side brush operates at a predetermined rotational speed that enables debris movement from alongside the sweeping machine into the path of the main brush. The rotational speed of the side brush is coordinated with the forward travel speed of the sweeping machine to provide optimal debris collection from edge areas and corner locations. The side brush speed creates a sweeping action that dislodges debris from edge areas and propels the debris toward the central cleaning path.
[63] The main brush (14) receives debris directed by the side brush and combines the edge debris with debris collected directly from the central sweeping path. The coordinated operation between the side brush and the main brush enables comprehensive debris collection across the full width of the cleaning area. The side brush extends the effective cleaning width beyond the main brush coverage area to include edge areas and corner locations that would otherwise remain uncleaned.
[64] The solution approach combines electric propulsion systems with integrated hydraulic operations to address the technical limitations of conventional sweeping machines. The electric propulsion system eliminates emissions during operation and reduces noise generation compared to internal combustion engine systems. The electric power system provides precise speed control and torque characteristics that enhance operational performance on varying surface conditions.
[65] The hydraulic system integration with electric power enables responsive control of cleaning components including brush positioning, hopper operations, and debris collection systems. The integrated control system coordinates hydraulic operations with vehicle movement to maintain optimal cleaning performance during directional changes and speed variations. The hydraulic-electric integration provides power management flexibility that adapts to varying operational demands and surface conditions.
[66] The electric power system enables enhanced maneuverability through advanced wheel control systems that provide steering capabilities beyond conventional mechanical arrangements. The electric drive system enables independent wheel control and directional positioning that improves turning capability in confined spaces. The enhanced maneuverability reduces the number of cleaning passes required to achieve complete coverage in complex operational environments.
[67] The integrated hydraulic-electric system provides superior cleaning performance through coordinated operation of all cleaning components under centralized control management. The coordinated system operation maintains consistent cleaning effectiveness across varying operational conditions and surface types. The integrated approach eliminates the operational limitations of conventional sweeping machines while providing enhanced environmental compatibility and operational flexibility for industrial cleaning applications.
