(2) rotating speed when described turbine raises again, and the turbine outlet working liquid body begins to impact the guide vane back, guide wheel moment≤0 o'clock, and guide wheel is rotated in the forward, and the absolute velocity of guide wheel export liquid changes, and making the guide wheel output torque is 0 (being the coupling state).
The action principle of described braking one-way element is:
The power of motor transmits by described pump impeller, turbine and working liquid body.Because the speed of described pump impeller is greater than the speed of turbine during proper functioning, so the described braking one-way element of motor forward surmounted, and motion does not have influence mutually between pump impeller and turbine.When secondary speed is higher than the pump impeller rotating speed, be that described turbine is kept rotating by counter the dragging of car load, but pump impeller has been lower than secondary speed, at this moment described braking one-way element is owing to the relative velocity direction of pump impeller and turbine changes and counteresteer, turbine will directly drive pump impeller and move together so, owing to be the anti-motor that drags, whole chassis is stopped.
The utility model compared with prior art has following advantage and beneficial effect:
(1) simple and ingenious structure, the guide wheel one-way element of tradition fluid torque converter is below wheel stand, if but in the built-in crankcase, then require the physical dimension of fluid torque converter less, there is not the mounting point by conventional construction guide wheel one-way element, in the utility model, the guide wheel one-way element is shifted out the pump impeller shell, be arranged on the outside of output gear, be connected with guide wheel cover for seat, guide wheel shaft bush between guide wheel one-way element and the wheel stand, simultaneously stopboard is fixed on the crankcase, and the structural design uniqueness has solved the problem that the built-in crankcase of fluid torque converter can't miniaturization.
(2) Perfect in shape and function, in the utility model, the braking one-way element and the rolling bearing (also can adopt unidirectional deep groove ball bearing) of motor have been increased with rolling bearing and one-way element integral structure at pump impeller seat and turbine shaft inner room, solved the problem (output gear is anti-when dragging, and pump impeller and turbine locking are one) of motor anti-dragged brake, make the more perfect function of fluid torque converter, vehicle driving is safer.
(3) applied range, the utility model physical dimension is little, can be widely used in forming automatic transmission with transmission system in the engine crankcase of two-wheeled, motor tricycle or four-wheel motor vehicle, has very big market potential.
