Embodiment 1
[0034] figure 1 It is a structural schematic diagram of a device for driving a tracked vehicle to steer according to an embodiment of the present invention.
[0035] see figure 1, the device that is used to drive the steering of crawler vehicle of embodiment, comprises: two driving motors 3a and 3b (the left side is driving motor 3a, the right side is driving motor 3b), two planetary coupling devices 2a and 2b (left side is The planetary coupling device 2a, the right side is the planetary coupling device 2b) and a steering motor 4; the output shaft of the driving motor 3a is connected with the drive wheel 1a on the left side of the tracked vehicle through the planetary coupling device 2a, and the output shaft of the driving motor 3b is connected through the planetary coupling The device 2b is connected with the driving wheel 1b on the right side of the tracked vehicle; the output shaft of the steering motor 4 is connected with the planetary coupling device 2a and the planetar...
Embodiment 2
[0053] The present invention also provides a method for driving a tracked vehicle to turn, which is applied to the above-mentioned device for driving a tracked vehicle to turn.
[0054] The method for driving a tracked vehicle to turn includes:
[0055] When the tracked vehicle is running straight or when the turning radius of the tracked vehicle is not less than the first preset threshold and not greater than the second preset threshold (normal steering), the device for driving the tracked vehicle to turn is in the straight driving mode, at this time, control the ring gear brake 17 to brake, control the external electromagnetic clutch to disconnect the output shaft 15 of the steering motor 4 from the first steering motor shaft gear 11a, and control the internal electromagnetic clutch to disconnect the output shaft 15 of the steering motor 4 The connection between the shaft 15 and the second steering motor shaft gear 14a is disconnected, and the steering motor 4 stops driving;...
