Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and the scope of protection of the utility model cannot be limited with this.
In the case of can not being solved in time when existing trolley faces environmental change and the system failure, this patent specific aim
A kind of dual drive system mechanical structure more applied of offer, the mechanical system can not only solve the safety after topographic change with
Stationary performance problem, and drive system can be switched so that when one of drive system breaks down, trolley can continue to
Movement reaches the function of preventing emergency.
Specifically in the Mechanical Fundamentals of traditional single-drive system, synchronous belt slide unit module is increased, basic drive is made
The DC speed-reducing and wheel of dynamic system can change horizontal position, and the combination of two groups of steering engines and connecting rod makes basis driving system
The motor of system can change the position on vertical space with wheel.Work as speed, when landform is applicable in high chassis, control module 9 can be with
Steering engine is driven to change angle by controlling steering engine drive module, so as to adjust chassis height.Work as speed, landform is suitble to low chassis
