Description
Technical field
The utility model is related to gear arrangement field, and specifically a kind of working truck hydraulic machinery is combined buncher
Device.
Background technology
Vehicle during traveling, the load suffered by it be with road surface situation, traveling state and vehicle body oneself
Weight constantly conversion, for high-power special Working vehicle, such change is especially apparent.With job that requires special skills vehicle phase
Than the operating mode that normal road vehicle is faced is single and transmission power is small, has grade gear low cost and disclosure satisfy that the operating mode of road
It is required that.But because the power of Special work vehicle transmission is big and environment is severe, the continuous fluctuating change of load suffered by it is general
Logical step change transmission can not meet best power performance and fuel economy of the vehicle under each operating mode.Traditional stepped transmission case
Although different operating modes can be adapted to by shifting gears, such as climb, it can only transmit power according to fixed gearratio,
The rotating speed of continuous variable cannot be exported, if increasing the gear of gearbox, the complexity of the structure of speed changer machinery will be increased,
And increase cost, increase space and operating difficulties, seriously constrain the raising of its performance.
Compared with the gearbox for having level, variable speed is the ideal form of system of vehicle transmission, and it can be according to the operating mode on road surface
Vehicle is set to travel at optimum condition with the performance of engine.During the traveling of vehicle, load suffered by it with road surface work
Condition constantly changes.Buncher can be such that gearratio is adjusted accordingly with the operating mode of extraneous load and road,
So that the engine of vehicle by after buncher can with the kinetic energy required for vehicle reach it is optimal match, due to passing through
The regulation of transmission gear ratio make engine be operated in best power source linearity curve or optimal economic it is characteristic near, improve
The fuel economy of vehicle.The continuous transformation of speed can be realized simultaneously, with the step load phase produced when having grade transforming gear
Than buncher is not in then the phenomenon, so as to reduce the impact in Vehicle Shifting, improves the comfortable of vehicle
Property.Because being applied on special vehicle for buncher just becomes the emphasis of transmission for vehicles research.

But power is transmitted due to frictional force that its main belt wheel and metal derby friction are produced, thus size of its transmission power by belt wheel with
The limitation of pressure between coefficient of friction and working surface between metal derby rubbing surface, causes it to transmit the high-power and longevity
Life is not high.Hyaulic infinite variable speed utensil have the advantages that power density greatly with speed-regulating range width, it is Sino-Japan in the Research on transmission of vehicle
Benefit is taken seriously, but due to the leakage of hydraulic circuit, there is a problem of that efficiency is relatively low always in vehicle hydraulic transmission development.With it is pure
Machine driving is compared, hydraulicdriven efficiency be significantly lower than machine driving, and Hydraulic Elements especially high power hydraulic element system
Make more difficult.Electrodynamic type buncher is made up of generator, traction electric machine and control system.It has transmission efficiency,
Transmission power bracket and the advantage being easily controlled.But compared with hydraulic continuously variable transmission, its own quality is big, high cost, is passing
Pass needs very big quality and volume under Same Efficieney compared with hydraulic drive.
Accordingly, it would be desirable to a kind of hydraulic machinery that hydraulic drive and machine driving are composed in parallel by planetary gears without
Level gear arrangement, which incorporates hydraulic drive power density is big, speed adjustable range is extensively efficient with mechanical transmission excellent
Point, the power of whole system is adjusted using the small-power of hydraulic part, can reduce the manufacturing cost of Hydraulic Elements, improves whole
The efficiency of transmission system.
