Abstract

The invention belongs to the technical field of power transmission and particularly relates to a double-differential electromechanical compound transmission device. The double-differential electromechanical compound transmission device for a crawler vehicle has the technical scheme that the double-differential electromechanical compound transmission device mainly consists of two driving motors, two sets of three-gear planetary speed change mechanisms, a left confluence planetary bar, a right confluence planetary bar, two zero shafts, four pairs of connecting gears, two sets of speed reducing planetary bars, two sets of main brakes and two sets of lateral speed reducing mechanisms, wherein the two zero shafts are connected with the left confluence planetary bar and the right confluence planetary bar. The double-differential electromechanical compound transmission device has the advantages that the mode of the two driving motors is only adopted, two confluence planetary bars are arranged, two differentials are connected through two zero shafts similar to the double-power flow driving mode, the problem of backflow power transfer from an inner side crawler belt to an outer side crawler belt of the double-motor independent driving is solved, the power grade of the driving motors is effectively reduced, the driving motors can realize the straight running and steering functions, the functions of stepless driving, stepless steering, zero position steering and the like are realized, and the volume power density of the transmission device can be improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission, and in particular relates to a double differential electromechanical compound transmission device. Background technique [0002] Electric transmission has the advantages of flexible layout and stepless speed regulation. With the improvement of the efficiency and power density of electric transmission system, its application in tracked vehicles will be more extensive. The simplest tracked vehicle electric drive system uses two motors to independently drive one side of the track, and the steering of the tracked vehicle is realized through the speed difference between the two motors. However, during the small-radius turning process of tracked vehicles, the low-speed side track must provide braking force, and the high-speed side track must provide driving force, resulting in the return power from the low-speed track to the high-speed track, causing the power transmitted by the high-speed s...
