Abstract
A double-turbine hydrodynamic torque converter is characterized in that an input secondary gear part which is located between a turbine group and a wheel stand is provided with a limiting step for limiting the axial movement of the turbine group. The limiting step is used for axially positioning the turbine group. An adjusting gasket 1 is provided between a turbine hub and the limiting step. An adjusting gasket 2 is equipped on the outer end face of a bearing on the end of an input primary gear. The limiting range of the limiting step is controlled by the two adjusting gaskets. Thus the gap can be conveniently adjusted. The double-turbine hydrodynamic torque converter has the advantages that the fault problem of the failure of the turbine group and the guide wheel, etc. due to wearing resulted from hole retaining ring axial positioning failure is solved; the secondary turbine axial accumulative assembling gap is ensured to be within a range between 0.15mm and 0.3mm by adopting the limiting step on the central part of the input secondary gear to axially position the turbine group and adding adjusting gaskets; and the reliability of the torque converter is thus improved.
Description
Technical field
The utility model relates to a kind of twin-turbine torque converter.
Background technique
Twin-turbine torque converter is the transmission part that is used for engineering machinery, is used in combination with free wheel device, plays the effect that increases output torque, and main parts size comprises pump impeller, turbine group and guide wheel etc., and the turbine group comprises one-level turbine assembly and two-stage turbine assembly.
The turbine group of twin-turbine torque converter is exported by input one-level gear and input secondary gear and the free wheel device Cheng Yilu that confluxes, the working principle of twin-turbine torque converter is: the torque-converters the inside is full of fluid, motor drives the pump impeller rotation, the mechanical energy of pump impeller is converted into the kinetic energy of fluid in the pump impeller runner, fluid successively rushes at the blade of one-level turbine assembly and two-stage turbine assembly along with the guiding of pump impeller blade under action of centrifugal force, make one-level turbine assembly and two-stage turbine assembly obtain rotating speed, after fluid passes through one-level turbine assembly and two-stage turbine assembly, then rush at fixed guide vane, principle according to active force and reaction force, the fluid that rushes at guide wheel at a high speed produces a reaction force to the turbine group, thereby increases the output torque after the turbine group is confluxed.
Being used in combination of twin-turbine torque converter and free wheel device can realize automatic regulatory function, promptly regulates the rotating speed and the moment of torsion of one-level turbine assembly and two-stage turbine assembly automatically according to the size of external load.When complete machine was in the low-speed heave-load operating mode, free wheel device was the wedging state, and one-level turbine assembly and two-stage turbine assembly are the gearbox transmitting torque jointly; Along with the reduction of load, the rotating speed of one-level turbine assembly and two-stage turbine assembly raises gradually, and one-level turbine assembly output torque proportion reduces simultaneously, and two-stage turbine assembly output torque proportion raises; Further reduction along with load, the rotating speed of two-stage turbine assembly has surpassed the one-level turbine assembly after by velocity ratio by the rotating speed behind the velocity ratio, this moment, free wheel device became disengaged condition, and the one-level turbine assembly is equivalent to idle running, and only relying on the two-stage turbine assembly is the gearbox transmitting torque.
One-level turbine assembly and two-stage turbine assembly also can produce bigger axial force standing high speed fluid to impact in the transmitting torque, and the size of axial force changes along with the frequent change of operating mode.In the existing twin-turbine torque converter structure, establish the hole back-up ring in the turbine hub endoporus in the turbine group, utilize the end face of input secondary gear to withstand the hole and realize axially locating with back-up ring, for guarantee rational gap also need be between the end face of input secondary gear and hole be with back-up ring increase spline spacer.If the hole is improper with the back-up ring assembling, perhaps the turbine group makes back-up ring come off under the axial force of alternation is impacted, to cause whole turbine group to form bigger axial float, thereby make torque-converters turbine group and guide wheel, pump impeller interfere mutually, wear and tear, and cause torque-converters to lose efficacy.The back-up ring torque-converters wear out failure that causes that comes off often takes place.
Summary of the invention
The purpose of this utility model is to solve that existing twin-turbine torque converter turbine group axially locating hole comes off the problem that causes the torque-converters wear out failure with back-up ring and twin-turbine torque converter that a kind of high reliability is provided.
Solution of the present utility model is such: the position on the input secondary gear between turbine group and wheel stand is provided with the axially movable limited step of restriction turbine group, utilize limited step that the two-stage turbine assembly is carried out axially locating, prevent that turbine group direction to wheel stand on the input secondary gear from producing axial float.
Be lined with between turbine hub and the limited step and adjust pad one, in the exterior edge face of the bearing of importing one-level gear termination adjustment pad two is installed, adjust pad one adjust the turbine group relatively with the axial float displacement gap of input secondary gear, adjust the axial float displacement gap that pad two is adjusted input one-level gears.
Improvement of the present utility model has been to cancel the hole back-up ring of turbine group location, structure to the input secondary gear is changed, locating face is changed to the step locating face at middle part by the end face of input secondary gear, the gap of before assembling input secondary gear, measuring input secondary gear middle bench locating face and turbine group locating face, guarantee that by the mode that increases spacer this gap, place is between 0.05mm ~ 0.10mm, the input one-level of packing into then gear, before housing and gear box trap, measure the gap of input one-level gear-bearing right side and casing corresponding shaft bearing end face, guarantee that by the mode that increases spacer this gap, place is between 0.10mm ~ 0.20mm.The axial accumulation fit up gap that torque-converters after the assembling can be guaranteed the turbine group had not only been satisfied the torque-converters internal bearings and can not be stuck when temperature raises but also can play good axially locating effect to the turbine group in 0.15mm ~ 0.30mm scope.
The utility model has the advantages that, compared with prior art, cancelled the hole back-up ring that in the turbine hub endoporus of turbine group, is used to realize turbine group axially locating in the prior art, utilize the limited step at input secondary gear middle part that the turbine group is carried out axially locating, adjust pad by increasing, the axial accumulation fit up gap of guaranteeing the turbine group is in 0.15mm ~ 0.30mm scope, solve the prior art mesopore with the lost efficacy failure problems of caused turbine group wear out failure of back-up ring axially locating, improved the reliability of torque-converters.
