Tracked vehicle electromechanical composite transmission device and composite transmission control method thereof

Abstract

The invention discloses a tracked vehicle electromechanical composite transmission device and a composite transmission control method thereof. The tracked vehicle electromechanical composite transmission device comprises a transmission case shell, wherein the transmission case shell is internally provided with a straight driving motor, and the straight driving motor is mechanically connected witha straight driving gear A through a straight driving deceleration row; the straight driving gear A is meshed with a straight driving gear B, a left planet row is arranged on the left side of the straight driving gear B, a right planet row is arranged on the right side of the straight driving gear B, and the straight driving gear B, the left planet row and the right planet row are fixed to the sametransmission shaft; the left planet row is mechanically connected with a left side transmission input end located outside the transmission case shell, and a left side transmission output end is mechanically connected with a left driving wheel; the right planet row is mechanically connected with a right side transmission input end located outside the transmission case shell, a right side transmission output end is mechanically connected with a right driving wheel, and the transmission case shell is further internally provided a steering motor arranged opposite to the straight driving motor. The problem that it is difficult to keep straight driving due to inconsistent output rotating speed of motors on the two sides of the tracked vehicle is solved.

Description

technical field [0001] The invention belongs to the technical field of power assembly components, and relates to an electromechanical compound transmission device of a crawler vehicle and a compound transmission control method thereof. Background technique [0002] With the development of core key component technologies such as power electronics technology, control technology, high-power permanent magnet synchronous motors, and high-performance batteries, there are more and more researches on the application of electric drives in tracked vehicles. Tracked vehicles are generally heavier than wheeled vehicles, have narrower space on the vehicle, and have more transmission functions. Therefore, the requirements for power indicators, power-to-volume ratio, and power-to-weight ratio of components such as motors and batteries are very high. How to organically integrate the motor and machinery under the premise of the limited technical level of the components, meet the layout requi...
