The working principle of the invention is as follows:
normal driving: the walking motor 1 works, the steering motor 17 does not work, the walking motor 1 drives the first main shaft 2 to rotate, the first main shaft 2 is fixedly connected with the tooth holder 3, and then the tooth holder 3 is driven to rotate. The walking gear A6 is matched with the walking gear C8 for meshed transmission, the walking gear B7 is matched with the walking gear D9 for meshed transmission, and the walking gear C8 and the walking gear D9 are fixedly connected with the second main shaft 10. The gear sleeve 4 is driven by the sliding of the sliding block 5, so that the high-low speed gear switching is realized. When the sliding block 5 is in a high-speed gear (namely, the position shown in fig. 3), the tooth holder 3 and the travelling gear A6 are connected into a whole through the tooth sleeve 4, the tooth holder 3 drives the travelling gear A6 to rotate, and the second main shaft 10 is driven to rotate through the meshing transmission of the travelling gear A6 and the travelling gear C8 so as to drive the travelling gear D9 to rotate. Although the traveling gear D9 meshes with the traveling gear B7, the traveling gear B7 and the first main shaft 2 can rotate relatively, and therefore, the transmission of power is not affected. When the sliding block 5 is in a low-speed gear, the tooth holder 3 and the walking gear B7 are connected into a whole through the tooth sleeve 4, the tooth holder 3 drives the walking gear B7 to rotate, and then the walking gear D9, the second main shaft 10 and the walking gear C8 are driven to rotate. Although the running gear C8 meshes with the running gear A6, the running gear A6 and the first spindle 2 can rotate relatively, and therefore, the transmission of power is not affected. The walking gear E11 is fixedly connected with the third main shaft 12, and the walking gear D9 rotates to drive the walking gear E11 and the third main shaft 12 to rotate. The third main shaft 12 rotates to drive the plurality of first planetary gear inner gears 13 and the plurality of second planetary gear inner gears 14 to synchronously rotate, and because the outer teeth of the first planetary gear ring 15 and the outer teeth of the second planetary gear ring 16 are respectively meshed with the steering gear set, the first planetary gear ring 15 and the second planetary gear ring 16 are limited by the steering motor 17 and are not fixed to rotate, so that the first planetary gear inner gears 13 drive the first outer gear rack 22 to rotate, and the second planetary gear inner gears 14 drive the second outer gear rack 23 to rotate; the first external gear rack 22 and the second external gear rack 23 synchronously rotate in the same direction and are connected with the tracks on two sides of the tracked vehicle to realize the forward or backward movement of the tracked vehicle.
The vehicle turns: when the tracked vehicle needs to turn, the steering motor 17 works, and the steering motor 17 drives the first steering gear 18, the second steering gear 19 and the third steering gear 20 to rotate; the third steering gear 20 rotates and simultaneously drives the fourth steering gear 21 and the second planetary gear ring 16 to synchronously rotate, and the fourth steering gear 21 rotates and drives the first planetary gear ring 15 to rotate. At this time, the first planetary gear ring 15 rotates in synchronization with the second planetary gear ring 16 in the opposite direction. The first planetary gear rings 15 rotate to drive the first planetary internal gears 13 to rotate and further drive the first external gear frames 22 to rotate; the second planetary gear rings 16 rotate to drive the second planetary inner gears 14 to rotate, and further drive the second outer gear frame 23 to rotate. The first external gear rack 22 and the second external gear rack 23 synchronously rotate reversely, and the steering of the tracked vehicle is realized without braking and braking resistance.
By changing the forward rotation or the reverse rotation of the steering motor 17, the left rotation or the right rotation of the crawler is achieved. During normal running (running motor 1 is operated), steering motor 17 is operated, and at this time, the first planetary gear and the second planetary gear form a differential speed, so that steering during running of the tracked vehicle can be realized. When the travel motor 1 is not operated and the steering motor 17 is operated, the in-situ steering is realized.
