Abstract
Description
The present invention relates to a dual damper type torque converter, and more particularly, to a dual damper type torque converter in which a damper unit has a parallel structure and a plurality of springs are provided to mitigate the transmission of a torsional vibration transmitted from a torque converter to an engine.
Generally, a torque converter for an automatic transmission is disclosed in Korean Patent Laid-Open Publication No. 1998-017124.
1 and 2, a
The
However, the
It is an object of the present invention to provide a dual damper type torque converter in which a damper unit has a parallel structure and a plurality of springs are provided to alleviate a torsional vibration transmitted from a torque converter to an engine.
A dual damper type torque converter of the present invention includes a front cover, an impeller coupled to the front cover and rotating integrally, a turbine disposed at a position facing the impeller, and a turbine disposed between the impeller and the turbine, A piston positioned between the front cover and the turbine in the axial direction, and a rotor disposed between the piston and the turbine in an axial direction to absorb impact and vibration acting in the rotating direction And a damper portion,
Wherein the damper portion comprises a first damper rotating integrally with the turbine and a second damper positioned between the piston and the first damper in an axial direction and relatively rotatable with respect to the first damper;
At least one first spring extending between the first damper and the second damper and extending in the circumferential direction, one end of the first spring being connected to the first damper and the other end being connected to the second damper, And at least one second spring connected to the damper and the other end connected to the piston and extending in the circumferential direction.
The second damper is formed in a branched shape in the radially outer side, and one branched end of the second damper is formed to be inclined toward the first damper, and the other branched end of the second damper is branched from the second And is provided in a form of wrapping a spring;
And a radially outer end of the first damper is provided to surround the first spring.
The branched one end of the second damper is spaced apart along the circumferential direction of the second damper.
The apparatus of claim 1, further comprising: a coupling member coupled to the first damper to form an opening radially outwardly open;
And the radially inner end of the second damper is slidably inserted into the opening of the engaging member so that the radially inner end of the second damper is supported.
The dual damper type torque converter according to the present invention is a dual damper type torque converter in which a damper unit has a parallel structure and a plurality of springs are provided to increase the maximum twist angle between the piston and the damper unit, so that the torsional vibration transmitted from the torque converter to the engine is relaxed, The performance is improved. And can be used in a high-performance engine, thus saving the cost of purchasing an expensive and complicated damper.
