Abstract

The invention relates to a double-side driving motor and two-gear automatic gearbox integrated independent driving system. The system comprises a driving motor, a gearbox, a brake, a side speed reducer and a driving wheel connected in sequence; the gearbox comprises a planet gear set and a synchronizer; an input shaft of the gearbox is connected with a sun gear of the planet gear set; the synchronizer is connected with a gear ring of the planet gear set; an output shaft of the gearbox is connected with a planet gear of the planet gear set; the synchronizer can axially move along the gear ringof the planet gear set; and gears are arranged at two axial ends, and can be respectively engaged with a high-speed gear fixed on the gearbox and a low-speed gear fixed on the output shaft. The systemguarantees the output characteristics of low speed, high torque, high speed and constant power of an electric transmission system, meets the platform requirements of high speed and high passing property, is compact in overall structure, and can fully use the torque and the power of the motor under different gears.

Description

technical field [0001] The invention relates to the technical field of variable speed drive, in particular to an independent drive system integrating a double-side drive motor and a two-speed automatic transmission. Background technique [0002] With the development of unmanned platform technology, unmanned platforms with high maneuverability and high passing capacity can be applied in the field of anti-terrorism to meet the needs of special road environments and complex road conditions. Hybrid drive technology reduces fuel consumption in pure electric mode, can realize energy self-management, can reduce fuel consumption and emissions without reducing power performance, provides sufficient power guarantee for equipment, and saves a lot of space for layout equipment. Therefore, hybrid drive is an important development trend of ground unmanned mobile platforms. [0003] The existing hybrid drive system mainly connects the drive motor directly to the side reducer, which canno...
