Abstract

The invention provides a tracked vehicle electric driving device with a straight driving power-assisted mechanism. The tracked vehicle electric driving device comprises a driving motor, a steering motor, a first reducing planet gear set, a second reducing planet gear set, a straight driving gear shift mechanism, a gear shift spindle, a neutral axis, a left neutral axis drive, a right neutral axis drive, a left confluence planet gear set, a right confluence planet gear set, a steering/driving motor, the straight driving power-assisted mechanism and a steering power-assisted mechanism, wherein the steering/driving motor is used for providing a second power source for driving a vehicle to steer and/or straight drive; the straight driving power-assisted mechanism is used for transferring power between the steering/driving motor and the gear shift spindle; the steering power-assisted mechanism is used for transferring power between the steering/driving motor and the neutral axis. The electric driving device provided by the invention is provided with the driving motor and the steering motor based on the characteristic of the actual use condition of a high-maneuverability tracked vehicle, and the steering/driving motor provides assisted power for the driving motor and the steering motor respectively through the straight driving power-assisted mechanism and the steering power-assisted mechanism and can provide low-speed driving power when the driving motor or the steering motor has a fault, so that the tracked vehicle electric driving device has relatively high vehicle steering performance and system fault-tolerant capability.

Description

technical field [0001] The present invention relates to the technical field of electric transmission devices for vehicles, in particular to the technical field of electric transmission devices for high mobility crawler vehicles, in particular to an electric transmission device for crawler vehicles with a direct driving assist mechanism. Background technique [0002] Conventional high-mobility tracked vehicles have accumulated a large number of statistical data that are sufficient to characterize their operating conditions. Based on these data, the following viewpoints have been put forward: the maximum road speed of the vehicle can reach 75km / h, and the maximum off-road speed can reach 45km / h; The actual use speed of the vehicle is far less than the speed achieved in all evaluative tests and demonstrations. The actual use monitoring data shows that its average driving speed is only 10-15km / h; During the cumulative working hours, only 8% of the vehicles have an average load g...
