Abstract
The utility model is a liquid flow trus section, relating to a liquid flow trus section of a locking automotive hydrodynamic torque converter. The utility model is formed by a pump impeller assembly, a turbine assembly and a guide wheel assembly, and has a shape of asymmetric oval. The pump impeller outer ring and turbine outer ring for forming the trus section is respectively formed by tangent arcs with different radius of six sections arcs and five sections arcs. The utility model has reasonable structure, small axial size, reduces the aspect ratio to 0.72, improves liquid flow performance, improves the driving efficiency by 84 to 86%, and meets the requirement of matching with an engine having displacement of 2.0L. The utility model can be widely applied in a multi-gear automatic speed changer car, especially a car having an engine with displacement of 2.0L.
Description
One, technical field
The utility model belongs to the automobile torque converter technical field of structures, is specifically related to the liquid stream circulate circle of enclosed type automobile torque converter.
Two, background technique
Automobile torque converter is a key components and parts that is applied in the pattern automatic transmission speed changer cars such as AT and CVT, and fluid torque converter is to utilize flowing of liquid that Engine torque is passed to automatic transmission reposefully.Fluid torque converter inside is made up of many parts, wherein is full of the automatic transmission transmission oil, is installed between motor and the automatic transmission.Extensively adopt the comprehensive fluid torque converter of forming by pump impeller, turbine, guide wheel and lockup clutch of single-stage two-phase three element enclosed type at present on the car.Pump impeller is a driving link, be connected with flywheel by integrally welded cap assembly, mechanical energy is converted into the liquid energy, guiding liquids impulse turbine blade, make blade rotation and drive turbine, realize that liquid can transform to mechanical energy, turbine is that Passive part is connected with transmission input shaft, guide wheel between above-mentioned two impellers is to be fixed on ATF pump by overrunning clutch and guide wheel shaft bush to cover, and lockup clutch then is installed between cap assembly and the turbine.
The liquid stream circulate circle of existing fluid torque converter, as the patent No. is " fluid torque converter " patent of ZL200720124832.x, disclosed liquid stream circulate circle is made of pump impeller assembly, turbine assembly and guide wheel assembly, the pump impeller outer shroud of pump impeller assembly and the turbine outer shroud of turbine assembly are the oblateness of asymmetric setting, and constitute by three sections different circular arcs are tangent respectively.Wherein the radius ratio between three of the pump impeller outer shroud sections circular arcs is 1.06:2.91:1, and the ratio of the radius between three sections circular arcs of turbine outer shroud is 1.01:2.97:1.The major defect of this liquid stream circulate circle is: the circulate circle flat ratio is up to 0.9～1, and axial dimension is very big, this is under the restricted condition of Hyundai Motor transmission system axial space, can not be applicable to the application in many gears automatic transmission case car, the more gear automatic transmission case cars of development are had bigger narrow limitation.
Three, summary of the invention
The purpose of this utility model is the deficiency at the liquid stream circulate circle of existing fluid torque converter, and a kind of circulate circle of fluid torque converter is provided, and has rational in infrastructurely, and axial dimension is less, can satisfy and discharge capacity is the characteristics such as needs of 2.0L Engine Matching.
The technological scheme that realizes the utility model purpose is: a kind of circulate circle of fluid torque converter is made of pump impeller assembly and turbine assembly and guide wheel assembly.The pump impeller outer shroud of pump impeller assembly and the turbine outer shroud of turbine assembly all are set to asymmetrical oblateness, help flowing of liquid, satisfied the flattening requirement of car with the fluid torque converter circulate circle, it is characterized in that: the width of oblate circulate circle of the present utility model is 47.25 millimeters, highly is that 65.79 millimeters, flattening rate are 0.72.The asymmetric oblateness of pump impeller outer shroud constitutes by the circular arc of six sections different radiis is tangent, and the ratio of the radius between its six sections circular arcs is 1.54:1.4:6.99:2.48:2.21:1.The asymmetric oblateness of turbine outer shroud constitutes by the circular arc of five sections different radiis is tangent, and the ratio of the radius between its five sections circular arcs is 1.88:1.66:7.72:2.33:1.
After the utility model adopts technique scheme, main effect is: owing to constitute the pump impeller outer shroud and the turbine outer shroud of asymmetric oblate circulate circle, form by the circular arc of six sections and five sections different radiis is tangent respectively, thereby have rational in infrastructure, axial dimension is less, and the flattening rate is reduced to 0.72, has improved the mobile performance of liquid, transmission efficiency brings up to 84～86%, and having satisfied with discharge capacity is the characteristics such as coupling needs of 2.0L motor.
The utility model can be widely used in many gears automatic transmission case car, is specially adapted in the car that discharge capacity is the 2.0L motor.
