Abstract
(EN)
A self-propelled electric mower has a machine body (1) equipped with a cutting apparatus, an electric motor for driving the cutting apparatus to rotate, and walking wheels (2) connected to the machine body. The machine body is equipped with a driving device (3) for driving the machine body. The driving device includes a transmission system (4) for driving the walking wheels and a power source (5) for driving the transmission system. The transmission system includes a belt transmission (4-1) connected with the power source, an external gear transmission (4-2) connected with the belt transmission, and an internal gear transmission (4-3) drove by the external gear and engaged with the walking wheels. With its multi-speed transmission, the mower achieves high transmission rate and reduces not only output torque but also the volume and cost of the driving motor. The self-propelled electric mower reduces noise and saves energy.
(FR)
La présente invention concerne une tondeuse électrique autotractée comportant un carter (1) équipé d'un dispositif de coupe, un moteur électrique destiné à entraîner la rotation du dispositif de coupe et des roues assurant le déplacement (2) reliées au carter. Le carter est équipé d'un dispositif tracteur (3) assurant sa traction. Ledit dispositif tracteur comprend un système de transmission (4) entraînant les roues assurant le déplacement et une source d'énergie (5) actionnant le système de transmission. Le système de transmission comprend une transmission par courroie (4-1) reliée à la source d'énergie, une transmission extérieure par pignons (4-2) reliée à la transmission par courroie et une transmission intérieure par pignons (4-3) actionnée par la transmission extérieure par pignons et en prise avec les roues assurant le déplacement. Avec sa transmission à plusieurs vitesses, cette tondeuse est caractérisée par un rapport élevé et permet une réduction, non seulement du couple de sortie, mais également du volume et du coût du moteur d'entraînement. Cette tondeuse électrique autotractée est peu bruyante et économe en énergie.
