With the suspended shock absorbing mechanism of complexity.Really, the stronger equipment of this kind of cushioning ability, can when by more, larger barrier
To eliminate most vibrations, but due to the complexity of shock mitigation system so that such equipment cost is higher, general during failure
Logical personnel can not repair, and can only be repaired by professional.There is a kind of caterpillar chassis mechanism in addition, it is negative in order to improve it
Loading capability, typically by being connected from motor-driven reduction gearbox output shaft by chain structure with driving wheel, carried out so as to drive
Band rotates；But because chain and gear spacing are larger, when gear drives chain to rotate, driving wheel can not timely will be defeated
On the power transmission exported on shaft to crawler belt, cause control precision of the motor to crawler body mechanism inadequate, respond simultaneously
Speed is inadequate, in many occasions for needing accurate control bobbin movement, it is clear that inapplicable.
More structures that caterpillar drive is driven using two sets of wheel shaft structures of driving wheel and driven pulley of the system of suspension are not added,
I.e.：Driving wheel contact track is set by front end, rear end sets driven pulley contact track, when driving wheel drives crawler belt to rotate,
Drive driven pulley to rotate by the rubbing action of crawler belt, realize the driving effect to crawler body mechanism.But such sets
It is standby therefore to have lacked BOGEY WHEEL and guide wheel mechanism due to being not provided with damping, when crawler body mechanism pass through it is uneven
Barrier when, only the margin location of tracked front-end and back-end is equipped with material contact, and other positions below crawler belt do not have
Stressing device, phenomenon is now easily deformed upon, if load is larger and more sharp by concavo-convex barrier in crawler body mechanism
Sharp, crawler belt easily deforms upon even crack conditions.
