The analysis of the problem of the derailment of the crawler transport vehicle is of great significance to the performance improvement and reliability improvement of the entire crawler travel device. The factors affecting the track take-off in actual work are very complicated. On the one hand, it is the impact and vibration caused by various external driving conditions, various road surfaces, obstacles, etc.; on the other hand, between the internal parts of the mobile system Collision, friction, etc. directly affect the meshing of the crawler belt and the driving gear teeth. Under certain extreme conditions, the meshing failure may occur, and the crawler belt and the driving wheel may fall off, causing the occurrence of the wheel-breaking fault.

Therefore, it is necessary to comprehensively consider the above-mentioned influencing factors to carry out research work on the steering performance of the tracked action system to reveal the reasons for the track off-track. Wangdu Ore Engineering Transporter Rubber Track Chassis

DC brushless motors have fast response, large starting torque, and can provide rated torque from zero speed to rated speed, but the advantages of DC motors are also its shortcomings, because DC motors are rated load. For constant torque performance, the armature magnetic field and the rotor magnetic field must be maintained at 90°, which is achieved by carbon brushes and commutators. The carbon brush and the commutator generate sparks and carbon powder when the motor rotates.

Therefore, in addition to causing damage to the components, the use occasions are also encountered. AC motors do not have carbon brushes and commutators. They are maintenance-free, rugged, and widely used. However, to achieve the equivalent performance of DC motors, complex control technology can be used. The crawler crawler chassis can be installed with a crawler positioning device between the roller and the traveling mechanism in order to reduce the displacement of the contact wheel between the roller and the traveling mechanism during the running or during the whole machine transportationand typical.
