Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] The present invention is an electric vehicle driving axle driven by double motors and adjustable in speed. The structure is as follows: figure 1 , 2 As shown, the main resolver 4, the main motor 1, the planetary gear train 2, the differential 3, and the speed-regulating resolver 6 are coaxially connected in sequence between the two wheels 9. The speed motor 5, the main motor 1 and one of the wheels 9 are connected through the left axle housing 7, the two ends of the speed regulating motor 5 are respectively connected with the planetary gear system 2 and the speed regulating resolver 6, and the speed regulating resolver 6 is connected with the other wheel 9 Connected through the right axle housing 10.
[0027] The main motor 1 and the speed-regulating motor 5 are coaxially arranged side by side, and both use inner rotor motors; the ma...

The invention discloses an electric vehicle drive axle by two motors for speed regulation. A main resolver, the main motor, a planetary gear train, a differential mechanism and a speed regulation resolver are coaxially connected between two vehicle wheels in sequence; the differential mechanism is coaxially sleeved with the speed regulation motor; the main motor is connected with one vehicle wheel through a left axle housing; the two ends of the speed regulation motor are connected with the planetary gear train and the speed regulation resolver correspondingly; and the speed regulation resolver is connected with the other vehicle wheel through a right axle housing. The planetary gear train comprises a center wheel, four planet wheels, an inner tooth ring and a planetary carrier; and the four planet wheels are evenly distributed on the outer side of the center wheel and the inner side of the inner tooth ring through the planetary carrier, the planetary carrier is connected with the main motor, the center wheel is connected with the differential mechanism, and the inner tooth ring is connected with the speed regulation motor. According to the electric vehicle drive axle, the two motors work alternately or output torque according to different combining forms, the best control strategy is adopted, the electric vehicle drive axle can adapt to various complex driving conditions at the smallest energy consumption, and the energy utilization rate of an electric vehicle is greatly increased.
Description
technical field [0001] The invention belongs to the technical field of automobile engineering, and in particular relates to an electric vehicle driving axle driven by double motors and speed-regulated. Background technique [0002] Vigorously develop oil-electric hybrid, oil-gas hybrid, pure electric vehicles, etc., especially large-scale pure electric buses and sightseeing electric vehicles, which have very prominent advantages in greatly improving urban traffic congestion, reducing vehicle emissions, improving environmental sanitation, and reducing noise. , has become one of the strategically important goals for the development of new energy vehicles in my country. [0003] Compared with internal combustion engine vehicles, electric vehicles have long been plagued by defects such as short driving range and slow charging, but they have outstanding advantages such as zero emissions, wide sources of electric energy, high driving power, and good acceleration performance. With ...
