Abstract
The invention discloses the methods that a kind of new type low temperature work Hydrodynamic transmission and its control are realized, by the transformer turbine output shaft for braking Hydrodynamic transmission, control Hydrodynamic transmission is forced to run under zero-speed bending moment operating condition, at this moment Hydrodynamic transmission absorbs the power that engine transmits, whole development of evil in febrile disease are at thermal energy, working fluid is quickly heated, it is easily achieved the heating of 100KW class large power, entire Hydrodynamic transmission is uniformly quickly heated by the proper flow of working fluid, to substantially shorten the starting time that Hydrodynamic transmission works in low temperature environment, to improve working efficiency, safety is substantially improved.
Description
Technical field
The invention belongs to Hydrodynamic transmission technical fields, especially can normally open at low temperature environment (subzero 10~50 degree)
Start building make Hydrodynamic transmission structure and corresponding control method.
Background technique
Existing widely used Hydrodynamic transmission cannot be at low temperature environment (subzero 10~50 degree) due to the requirement of its product structure
In normally start work.If you need to start after low temperature environment work then must be heated to room temperature, electrothermal tube is now generallyd use
Heating method (heats) below 10KW rank, always exists seriously uneasy when the heating speed slow time is long, heating is uneven and heating
The problems such as full property, influences working efficiency very big.
Summary of the invention
To solve the technical issues of mentioning in background technique, the fluid power speed change the present invention is intended to provide a kind of new type low temperature works
Device and its control method can safely and fast realize Hydrodynamic transmission itself uniformly quickly heating, to substantially shorten
The starting time that Hydrodynamic transmission works in low temperature environment allows common Hydrodynamic transmission to become the liquid that can be really suitble to low-temperature working
Power speed changer.
The present invention forces control Hydrodynamic transmission zero by the transformer turbine output shaft of braking Hydrodynamic transmission
It is run under fast bending moment operating condition, at this moment Hydrodynamic transmission absorbs the power that engine transmits, and whole development of evil in febrile disease are at thermal energy, to working fluid
It is quickly heated and (is easily achieved the heating of 100KW class large power), entire fluid power is become by the proper flow of working fluid
Fast device uniformly quickly heats.
The present invention is achieved by the following technical programs:
A kind of new type low temperature work Hydrodynamic transmission, including transformer turbine output shaft, the fluid torque-converter whirlpool
Wheel output shaft is connected with turbine output shaft control unit, and the turbine output shaft control unit is used for turbine output shaft system
It is dynamic.
As a kind of selection, turbine output shaft control unit is integrated in planet mechanical gear box.
A kind of control method of new type low temperature work Hydrodynamic transmission, artificially forces control zero Hydrodynamic transmission
It is run under fast bending moment operating condition.
Preferably, by braking transformer turbine output shaft Hydrodynamic transmission is transported under zero-speed bending moment operating condition
Row.
As long as theoretically whirling thrust load is sufficiently large to work in zero bending moment operating condition, when cannot allow long in real work
Between enter zero bending moment operating condition, can all not occur zero bending moment operating condition as far as possible usually, emphasis of the present invention is under artificial control intentionally
Actively enter zero bending moment operating condition, to realize speed changer rapid and uniform heating.Compared with existing Hydrodynamic transmission, pass through braking
The transformer turbine output shaft of Hydrodynamic transmission forces control Hydrodynamic transmission to run under zero-speed bending moment operating condition, at this moment
Hydrodynamic transmission absorbs the power that engine transmits, and whole development of evil in febrile disease quickly heat working fluid and (be easy to reality at thermal energy
Existing 100KW class large power heating), entire Hydrodynamic transmission is uniformly quickly heated by the proper flow of working fluid, thus
Substantially shorten the starting time that Hydrodynamic transmission works in low temperature environment, common Hydrodynamic transmission is allowed to become really be suitble to low temperature
The Hydrodynamic transmission of work.
Detailed description of the invention
Fig. 1 is conventional fluid torque variator structural schematic diagram；
Fig. 2 is new type low temperature work fluid power variator structural schematic diagram；
In figure: 1 input shaft, 2 transformer turbine output shafts, 3 fluid torque-converters, 4 planet mechanical gear boxes, 5 outputs
Axis, 6 turbine output shaft control units.
Specific embodiment
The invention will be further described with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, being traditional Hydrodynamic transmission structure, including input shaft 1, transformer turbine output shaft 2, liquid
Power torque-converters 3, planet mechanical gear box 4 and output shaft 5.
As shown in Fig. 2, new type low temperature work Hydrodynamic transmission is by increasing turbine output shaft control unit in the present embodiment
6, transformer turbine output shaft 2 is braked (according to planet mechanical gear box 4 by turbine output shaft control unit 6
Performance, turbine output shaft control unit 6, which can be easily achieved, carries out forced brake control to transformer turbine output shaft 2),
Performance characteristics (the i.e. fluid torque-converter 3 for making full use of the fluid torque-converter 3 of Hydrodynamic transmission that can largely generate heat under zero-speed operating condition
Under zero-speed operating condition, the power absorbed from input shaft 1 is completely converted into the torque-converters inherent characteristic of thermal energy).Common fluid power is allowed to become
Fast device is not in the case where changing structure, not increasing attachment, it is easy to realize that safe and efficient 100KW power class large power adds
Heat makes Hydrodynamic transmission itself that can have the function of quickly being heated to working fluid, and it is inefficient to reduce tradition
Electrothermal tube heating and power supply unit, so that safety be substantially improved.On the other hand, by the proper flow of working fluid to entire
Hydrodynamic transmission carries out uniformly quickly heating, thus substantially shorten the starting time that Hydrodynamic transmission works in low temperature environment, from
And working efficiency is improved, allow common Hydrodynamic transmission to become the Hydrodynamic transmission that can be really suitble to low-temperature working.
