Positive anti-change.Economic restructuring and investment in fixed assets, it is the chief motivation amount of middle heavy truck Industry Quick Development, basis
Engineering construction continues to keep increasing, to the huge pulling function in heavy truck market under the comprehensive function of superimposed factor favourable, heavy truck row
The rigid demand that industry market capacity expands and vehicle replacement is regenerated turns into base support.Road maintainance cost cancels and weight metering charging political affairs
The influence in heavy truck market is huge during plan is particularly to commercial car, is mainly reflected in the lightweight and medium-weight vehicle automation of vehicle
On.Tilt cab greatly simplify the process maintained to vehicle, can be rated as most classical in truck industry set
One of meter.Almost absolutely cab over engine heavy truck all supports turn over function at present, even previously this few function
Light truck, turnover technology is also more and more employed now.It but may be reversed and no doubt facilitate, but complicated switching mechanism is also unavoidable
Some problems can be gone out, subject matter shows several aspects：1st, light truck typically uses torsion bar type switching mechanism, and truck drives
Room own wt is larger, and it can not possibly be overturn by depending merely on manpower, so needing a set of power assisting device.And power assisting device
It is divided into torsion bar type and fluid pressure type again for from operation principle.Torsion bar type is exactly preferable by one or two elasticity in simple terms
Iron rod provide auxiliary power, driver's cabin is lifted by manpower.Torsion bar is twisted when driver's cabin drops to extreme lower position, bullet when lifting
Power discharges, so as to play a part of power-assisted.Torsion bar type driving cab power-assisted inverting mechanism has the advantages of property simple and reliable for structure is good,
But used with continuous, the elastic force of torsion bar can be more and more lower.2nd, Manual hydraulic upset system is exactly to be risen by hydraulic power
The system of driver's cabin.For power resources, hydraulic pressure upset system is also divided into manpower type and electrodynamic type.Due to upset driver's cabin
When be not a lot, manpower is enough to be competent at, so most of heavy trucks are all using Manual hydraulic upset system now.Hydraulic pressure is overturn
The maximum benefit of system is exactly that lifting force is sufficiently large, no matter multiple driver's cabin can be jacked up easily, this point is that torsion bar type helps
What Force system can not compare.But it also has shortcoming, and structure is too complicated, fault rate is higher than torsion bar type, to maintenance also have compared with
High requirement.For example the north in the winter time, hydraulic lifting system must use the hydraulic oil of more lower viscosity levels, otherwise can be difficult to
Rise driver's cabin.If encountering such a situation, met an urgent need in addition to changing hydraulic oil, it is necessary to pour handlance with hot water,
In addition, most of vehicle front panel when driver's cabin is overturn can all interfere with vehicle frame, so before upset
It must remember first to open front panel, otherwise front panel will be caused to damage.
