(3) the active force radius of the spring of torsional vibration damper is too little, and the force-bearing situation of spring is poor, and the torsional vibration damper functional reliability is lower, and damping property is relatively poor.
Summary of the invention
The technical problem to be solved in the present invention provides the fluid torque converter that a kind of axial dimension is little, easy for installation and damping property is good.
In order to solve the problems of the technologies described above, technological scheme of the present invention provides a kind of compact type fluid torque converter, it is characterized in that: comprise the evagination protecgulum with convex face, thrust ring is located in the evagination protecgulum, the flattening turbine is located on the thrust ring, and the flattening turbine is provided with the turbine axle sleeve; Be provided with lockable mechanism between flattening turbine and the evagination protecgulum, the flattening guide wheel is located on the flattening turbine, and flattening guide wheel two ends are provided with plane bearing; The flattening pump impeller is located on the flattening guide wheel, and the flattening pump impeller is connected with pump impeller axle sleeve, evagination protecgulum.
Preferably, described lockable mechanism is made up of the helical spring discoid piston that is provided with into even number.
Preferably, described helical spring all is located at the radially circumferential to the curved surface of described evagination protecgulum direction indent of described discoid piston, and described helical spring distribution diameter is greater than the external diameter of described flattening turbine.
When a kind of compact type fluid torque converter provided by the invention is worked, power is imported from the evagination protecgulum, the flattening pump impeller that drive links to each other with the evagination protecgulum, the flattening pump impeller stirs the automatic transmission fluid in the torque-converters, drive the flattening turbine rotation, automatic transmission fluid carries out the circulate circle action in torque-converters inside, because the centrifugal force the during rotation of flattening pump impeller, automatic transmission fluid can be under the effect of flattening pump impeller, get rid of laterally, rush at the flattening turbine in the place ahead, the footpath flows to shaft core position by the flattening guide wheel again, gets back to flattening pump impeller one side, the circulation that so goes round and begins again, power is passed to the flattening turbine that is connected with gearbox the ratio of change motor input torque and output torque.The width of circulate circle and diameter ratio narrow down to 0.2～0.25 from traditional 0.3～0.35, have shortened the installation shaft distance, are conducive to the installation of torque-converters and the increase of the automatic gear of automobile.Simultaneously torsional vibration damper is moved to the outside, oil stream circulation cross section outward, can make the torsional vibration damper performance optimization.
Device provided by the invention has overcome the deficiencies in the prior art, reduced the axial dimension of fluid torque converter, saved the space of axial position, make the installation of fluid torque converter easier, increased the active force radius of spring simultaneously, make torsional vibration damper work more reliable, damping property is better.
