Embodiment Construction

[0024] figure 1 Shown is a representative embodiment of a tracked vehicle electromechanical compound transmission for implementing the concepts of the present invention. The electromechanical compound transmission 100 includes four planetary rows, four motor / generators and three operating elements. The input power is transmitted to the ring gear 87 of the second planetary row 80 through the idler spur gear 88, and the planetary carrier 86 of the second planetary row is respectively connected with the planetary carrier 46 of the third planetary row and the ring gears 67, 57 are connected together. The sun gear 85 of the second planetary row is connected to the rotor 32 of the second electric motor / generator. The second motor / generator 30 is located between the second planetary row 80 and the electromechanical compound transmission clutch 12 . The active part 12 of the clutch of the electromechanical compound transmission is connected with the second motor / generator rotor 32,...

Abstract

The invention discloses an independent steering type electromechanical composite transmission device for a crawler. The independent steering type electromechanical composite transmission device comprises four planet rows, four electromotors / generators and three operation elements. Input power is transmitted to a gear ring of one planet row through an idler straight gear, is transmitted by the electromechanical composite transmission device, then, is output through planet carries of other planet rows, and is finally transmitted to drive wheels on the two sides of a vehicle body through side transmission. The independent steering type electromechanical composite transmission device can realize shunt transmission of power in the range of normal vehicle speed, and can realize backflow of brake power from the inner side to the outer side at steering time.

Description

technical field [0001] The invention relates to an electromechanical compound transmission device, in particular to an independent steering type electromechanical compound transmission device suitable for crawler vehicles. Background technique [0002] The electromechanical compound transmission tracked vehicle has good power, economy, and stepless steering performance. It is easy to realize vehicle informationization, remote control, unmanned driving and other functions. It is one of the future development directions of tracked vehicles. In 2001, the United States completed the research on a 20t-class lightweight crawler-type double-sided motor independent drive demonstration vehicle based on the M113. German Renke company and magneto company jointly developed high-power crawler EMT1100 electromechanical compound transmission. my country has carried out exploratory research on electromechanical compound transmission of tracked vehicles. [0003] Steering methods of tradit...
