Abstract
This invention relates to stub axis hydrodynamic torque converter, which forms an oil section between turbo wheel and pump wheel. The invention designs the section into the flat round shape with its large end facing outside, so the torsion absorber gives away large space to save the valuable space for axis installation and prepares good environment for the converter matching application on the car. Besides, the screw holes structures are located on front end of the pump wheel cover outskirt to decrease the size of the converter to improve the matching ability.
Description
Technical field
The present invention relates to a kind of fluid torque converter, relate in particular to a kind of SWB fluid torque converter.
Background technique
Along with the raising of rapid development of automobile industry and people's living standard, people have higher requirement to the ease-to-operate and the ride comfort of automobile.Many high-grade cars have all disposed fluid torque converter.The automobile of configuration fluid torque converter comes transmitting torque being used for leaning on the friction clutch transmitting torque to become by hydraulic oil in the past, make the connection of power become more steady, can guarantee that vehicle starting is steady, simultaneously, guide wheel in the fluid torque converter is by the effect of overrunning clutch, the turbine starting torque is increased, increased the starting torque of automobile, and torsional vibration damper has wherein reduced the torsional oscillation of the dynamic load and the elimination power train of power train; When having little time gear shift, bigger resistance do not cause engine misses in automobile running to the minimum speed of a motor vehicle or prominent the chance yet.
The fluid torque converter of domestic production at present all is to adopt circular or oval oil stream circulation cross section, torsional vibration damper all is arranged on from the nearer place of turbine shaft, the link position of torque-converters and engine crankshaft land causes the torque-converters axial dimension bigger all at the end face of torque-converters.Because present most of car is the horizontal front wheel driving mode of motor, the axial position of engine bin is less, the big fluid torque converter of axial dimension with gearbox supporting in be difficult to arrange, influenced the assembling amount of fluid torque converter on car to a great extent.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of SWB fluid torque converter, to reduce the axial dimension of torque-converters.
To achieve these goals, technical program of the present invention lies in having adopted a kind of SWB fluid torque converter, form an oil stream circulation cross section between turbine and the pump impeller, described oil stream circulation cross section is an egg circular section, and the major part of egg circular section outwardly.
Screw member on the pump impeller protecgulum is arranged on the periphery front end of pump impeller protecgulum.
Because it is major part egg circular section outwardly that oil is flowed the circulation Cross section Design, make the mounting point of torsional vibration damper inwardly abdicate the space, like this, the position of whole torsional vibration damper can interiorly be received, save out valuable axial installing space, created good conditions for the supporting application of fluid power torque-converters on car.In addition, the screw member is moved to the periphery front end of pump impeller protecgulum outward, reached equally and reduce the torque-converters axial dimension, improve the present invention and on f-w-d car, carry out supporting ability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, SWB fluid torque converter of the present invention, form an oil stream circulation cross section (shown in dotted line inside) between turbine 1 and the pump impeller 2, oil stream circulation cross section is an egg circular section, the major part of egg circular section outwardly, it is major part egg circular section outwardly that oil is flowed the circulation Cross section Design, make the mounting point of torsional vibration damper inwardly abdicate the space, like this, the position of whole torsional vibration damper can interiorly be received, and has saved out valuable axial installing space.Screw member on the protecgulum 3 of pump impeller 2 is arranged on the periphery front end of pump impeller protecgulum, can reach to reduce the torque-converters axial dimension, improves the present invention and carry out supporting ability on f-w-d car.
Claims (2)
1, a kind of SWB fluid torque converter forms an oil stream circulation cross section between turbine and the pump impeller, it is characterized in that: described oil stream circulation cross section is an egg circular section, and the major part of egg circular section outwardly.
2, SWB fluid torque converter according to claim 1 is characterized in that: the screw member on the pump impeller protecgulum is arranged on the periphery front end of pump impeller protecgulum.
