Description
(1) technical field
The invention belongs to transmission fields, are related to a kind of control method of power takeoff.
(2) background technique
In recent years, with the development of our modernizations of the country, the protection of environment is also increasingly paid attention to.Its sanitation cart
, also become indispensable tool because its operating efficiency is high, labor intensity is low.However, current environmental sanitation vehicles, for example sweep road
Vehicle, sweeper, high-pressure sewer flushing vehicle etc. need the special-purpose vehicle of the second power, most of to be still equipped with assistant engine.This work
Industry mode, high noise, oil consumption is high, maintenance is costly, exhaust emission is heavier.And due to the installation of the second power, not only
The weight of vehicle has been aggravated, and has occupied the space of a part, to reduce the volume of the other dedicated units of vehicle, such as
Water tank, dustbin etc..
Therefore, monomotor is to have become a kind of development trend without the second power special sanitation vehicle.Which is benefit
With engine in situ i.e. the first power or for vehicle prime mover be vehicle to run, dedicated unit provides power, is made an uproar with reaching reduction
Sound, the purpose reduce energy consumption, reduce discharge, reducing maintenance cost.
The monomotor drive form now occurred in the market, substantially there are three types of: the first is that power takeoff is mounted on vehicle
Two transmission shafts between, when work, vehicle is not walked, and transmission mouth of the power by front propeller shaft through power takeoff band is dedicated to drive
Specially set.Since equipment and running gear separate, the demand that vehicle works in walking can not achieve；
Second is that power takeoff is mounted between two transmission shafts of vehicle, and the function of cleaning in walking may be implemented.
But the driving of dedicated unit, it is to drive hydraulic oil pump as upper dress power source drive by power takeoff.Due to hydraulic drive
Mechanical efficiency it is low, cause to cause a large amount of power loss in transmission process, in the case where same acting, fuel consumption rate
It will greatly increase.
The third is to install a Full-power takeoff additional among engine in situ and gearbox, directly drive gearbox
Carry out the work of dress.Although way driving in this way is simple, implement comparatively laborious, control system is also more complicated,
General company is difficult to realize.
By patent consulting, for the multioutlet transfer case of monomotor low-speed walking operation special purpose vehicle vehicle, application
It number is 201010542718.5, which is mounted on the transmission shaft of chassis, including cabinet, is equipped with machine driving input port, hydraulic
Motor power input port, hydraulic oil pump input port, machine driving input port, the first operating equipment drive output port and the second operation
Device drives delivery outlet.May be implemented an engine can realize simultaneously the high speed traveling of vehicle, low speed drive a vehicle+drive first
Device drives delivery outlet and the second operating equipment driving mouth, low speed are driven a vehicle+drive the first device drives delivery outlet.It does so, it can
To realize the function of Mechanical Driven special equipment.
But since the internal structure of its transfer case gear limits, it can not achieve high speed and walks, and can normal operation
Operating condition.Also, since the internal structure of its transfer case gear limits, its movable shift fork is separately positioned on the output of transfer case
Axis, hydraulic motor displace axis, on the second equipment transmission shaft, control relatively complicated, and structure is more complicated.When each function switches over
When, it can not detect whether that shift fork in place, is easily damaged gear to it.
(3) summary of the invention:
The object of the invention is that providing one kind for single-engined special-purpose vehicle power takeoff, pass through reasonable power output
It is excellent effectively to reach energy-saving and emission-reduction, simple, the special-purpose vehicle gamut covering of environmentally protective, structure etc. for design and internal structure design
Point, meanwhile, in the case where can also realizing that special equipment runs well by the technical program, vehicle is not walked, and vehicle can be made
The work of zero speed.
The technical scheme is that a kind of control method of power takeoff, power takeoff includes shell, main shaft, driven shaft
And output shaft, output shaft include output I axis and output III axis, are provided with mainshaft gear, mainshaft gear sliding sleeve on main shaft, it is driven
Driven shaft sliding sleeve is provided on axis, it is characterised in that main shaft and driven shaft are on same axis, driven shaft sliding sleeve and main shaft tooth
Wheel matching setting, by driven shaft sliding sleeve and the connection of mainshaft gear engage and be implemented separately between main shaft and driven shaft and
It disengages, output I shaft pulley, output I shaft gear is provided on the output I axis, while exporting I axis connection to have variable pump,
Output II shaft gear, transmission gear a, output II shaft pulley, transmission gear a and output I are provided on the output II axis
Shaft gear is normal meshing state, output III shaft gear and transmission gear b is provided on the output III axis, and one end connects
There is hydraulic motor, it is characterised in that above-mentioned component realizes the output side of five kinds of power of power takeoff by different control methods
Formula, control method are as follows:
The first operating mode are as follows: driven shaft slides over to move to left under the drive of shift fork, engages it with mainshaft gear, main shaft
Gear slide sleeve is in middle position, and other axis are all failure to actuate.When being driven input port operating, main shaft, driven shaft operating are driven, thus will
Power is exported by transmission delivery outlet.The normal walking of vehicle may be implemented in this way.
Second of operating mode are as follows: mainshaft gear slides over to be moved under the drive of shift fork, is meshed with transmission gear a；When
When being driven input port operating, main shaft, mainshaft gear sliding sleeve, transmission gear a operating are driven；To drive output I shaft pulley, become
Amount pump, output II shaft pulley operating.Driven shaft slides over to be moved under the drive of shift fork, is meshed with transmission gear b.At this point,
