Abstract
Description
The present invention relates to a vehicle torque converter and a method for manufacturing the same, which improves workability when the blade is coupled to a turbine shell or an impeller shell.
Generally, a torque converter is installed between a vehicle engine and a transmission to transmit the driving force of the engine to the transmission using a fluid. Such a torque converter includes an impeller rotating under the driving force of the engine, a turbine rotated by the oil discharged from the impeller, and a reactor for increasing the rate of torque change by directing the flow of oil flowing back to the impeller in the direction of rotation of the impeller Quot; stator ").
The torque converter is equipped with a lock-up clutch (also called a "damper clutch"), which is a means of directly connecting the engine to the transmission, as power transmission efficiency may be degraded if the load acting on the engine is increased. The lockup clutch is disposed between the front cover and the turbine directly connected to the engine so that the rotational power of the engine can be transmitted directly to the transmission through the turbine.
This lockup clutch includes a piston that is axially movable on the turbine shaft. The piston is engaged with a friction material which is in friction contact with the front cover. The piston is fitted with a torsional damper capable of absorbing shock and vibration acting in the direction of rotation of the shaft when the friction material is engaged with the front cover.
The impeller described above includes an impeller shell and a plurality of blades coupled to the impeller shell. The turbine also includes a turbine shell and a plurality of blades coupled to the turbine shell.
Referring to the process of coupling the blade to the conventional impeller shell as follows.
An impeller shell provided with a through hole into which the blade can be fitted is conveyed along the automatic transport. The operator or industrial robot then inserts the blade into the through hole of the impeller shell and places the filler material at the same time as the impeller shell and the blade are engaged. The impeller shell and the blade are joined by fusion welding by heating the filler metal using a heating device.
However, when the impeller shell is transported by the automatic transfer device in the state where the filler metal is raised, the filler material may be out of position and may be fusion welded.
As described above, the conventional technology has a problem in that the welding position is changed because the position of the filler metal is changed in the process of transferring the impeller shell, so that the position of engagement of the impeller shell and the blade is changed. The improper coupling of the impeller shell and the blade may lead to a failure of the torque converter, which causes a problem of deterioration in quality and productivity.
In addition, there is a problem in that productivity is reduced due to a poor coupling of the impeller shell and the blade in the automated assembly process for mass production.
Therefore, the present invention has been proposed to solve the above problems, the object of the present invention is to increase the quality by preventing the coupling failure when the impeller shell and blade or turbine shell and blade is combined by welding in an automated process Another object of the present invention is to provide a torque converter for a vehicle and a method of manufacturing the same, which improve productivity.
In order to accomplish the above object, the present invention provides a turbine for a turbine, comprising: a front cover; an impeller coupled to the front cover to rotate together; a turbine disposed at a position facing the impeller; A lockup clutch having a piston directly connecting the front cover and the turbine, a local damper coupled to the lockup clutch and absorbing impact and vibration acting in a rotating direction, Lt; / RTI >
The impeller includes an impeller shell and a plurality of blades coupled to the impeller shell, and the blade provides a vehicle torque converter provided with a filler material insertion groove into which filler material for welding is inserted into a portion coupled with the impeller shell.
The filler metal insertion groove is preferably provided at the tip of the blade adjacent to the impeller shell.
The filler metal may include a curved groove portion inserted into the filler metal insertion groove and an extension portion which is bent from the curved groove portion and extends in parallel with each other.
The present invention also provides a method for manufacturing an impeller shell of a vehicle torque converter, the method comprising: transferring an impeller shell provided with a blade insertion hole to an automated assembly device, wherein a plurality of filler material insertion grooves are provided in the blade insertion hole of the moved impeller shell. It provides a method of manufacturing a torque converter for a vehicle comprising the steps of disposing a filler material, disposing the filler material in the filler metal insertion groove, heating the filler material with a heating apparatus.
The method may further include processing the filler metal insertion grooves at the ends of the plurality of blades before arranging the plurality of blades provided with the filler metal insertion grooves in the blade insertion holes of the impeller shell.
Such a present invention has the effect of increasing the quality as well as increase the productivity by preventing the coupling failure because the filler metal is always placed in a fixed position and fused when combining the impeller shell and the blade using an automated assembly device.
