Description
Technical field
The present invention relates to power transmitting apparatus field, specifically a kind of flexible power takeoff and drive method.
Background technique
Blower used in sanitation cart, the groove tank driving mechanism of bulk cement carrier, agricultural machinery operating mechanism all have it is some common
Point, the operating mechanism of agricultural machinery such as plow the mechanism of plowing of vehicle, the harvest mechanism of harvester, especially under acclive environment
Or in rugged field, the problem of cannot all being matched there is torque and revolving speed.
For the fan rotor used in the road sweeper in sanitation cart, power has reached 30-50KW, in order to drive
The blower, road sweeper have no alternative but an additionally mounted diesel engine dedicated for driving blower, but commercialization in 2019
Vehicle will enforce VI emission regulation of state, and dedicated for drive blower diesel engine because cannot install after-treatment device or
The cost for installing after-treatment device is very big and must cancel, therefore special-purpose vehicle sanitation cart industry uses single engine gesture instead must
Row.Sanitation cart and special-purpose vehicle be such as currently on the market: road sweeper uses single-shot (only single engine) instead, and only there are two types of sides afterwards
Formula driving is available: i.e. motor driven and sustainer driving.
1, power drive blower, since blower starting torque is especially big, generally up to thousands of ox are transmitted using from sustainer
Rice often causes engine misses because loading too greatly when starting blower under engine idle conditions, and starts with starting is carried
When machine, because load excessive makes engine be difficult to start；
2, using the so powerful fan rotor of motor driven, often occur suppressing the problem of bad motor burns circuit；
3, both the above driving method all must pass through power taking out outside above-mentioned two problems using power takeoff transmitting power
When device transmits power drive such large torque blower, the secondary serious mill of friction of power takeoff will cause since starting torque is very big
Damage, causes power takeoff service life too short.
Solve the above problems, the gearbox using existing maturation be it is feasible, still, the gearbox of existing maturation
The volume for loading such powerful equipment gearbox will become very big, meanwhile, the problem of can not be ignored, is: existing market
On gearbox it is all extremely complex, precision is very high, and especially price is too high, it is difficult to popularity.Therefore in vast work
Journey vehicle or agri-vehicle field mostly use greatly import device or directly adopt import vehicle.By statistics, in Xinjiang region, plough
Ground vehicle 90% is with upper inlet in European and American areas, and often rare and use reliability is poor by the domestic Chefei that plows.
If solving the above problems or capturing gearbox production technology problem or look for another way and find a conjunction
The design path of reason is corresponding to solve the problems, such as.
Summary of the invention
The purpose of the present invention is to provide a kind of flexible power takeoff, the mentality of designing of the system mainly passes through simplified design
So that power takeoff is able to achieve the purpose of low-speed big starting and the work of small torque high speed under heavy load condition, avoids heavy load in height
Fast large torque causes engine misses or motor burning when starting, and avoids the problem that power takeoff Fast Wearing.It reduces simultaneously
The excessively complicated problem of production technology in conventional drivetrain, makes to become torque, the vision of flexible operating of speed change degree becomes a reality,
