Abstract
A damper apparatus that includes an input to which a torque from an engine is transferred; an output; a first intermediate element; a second intermediate element; a first elastic body configured to transfer the torque between the input and the first intermediate element; a second elastic body configured to transfer the torque between the first intermediate element and the output; a third elastic body configured to transfer the torque between the input and the second intermediate element; a fourth elastic body configured to transfer the torque between the second intermediate element and the output; and a fifth elastic body configured to transfer the torque between the first intermediate element and the second intermediate element.
Claims20
A damper apparatus comprising:
- an input to which a torque from an engine is transferred;
- an output;
- a first intermediate element;
- a second intermediate element;
- a first elastic body configured to transfer the torque between the input and the first intermediate element;
- a second elastic body configured to transfer the torque between the first intermediate element and the output;
- a third elastic body configured to transfer the torque between the input and the second intermediate element;
- a fourth elastic body configured to transfer the torque between the second intermediate element and the output;
- and
- a fifth elastic body configured to transfer the torque between the first intermediate element and the second intermediate element, wherein
- the third and fourth elastic bodies are disposed on an outer side of the first and second elastic bodies in a radial direction of the damper apparatus, and
- the fifth elastic body is disposed on the outer side of the first and second elastic bodies in the radial direction with a distance from the third and fourth elastic bodies in an axial direction of the damper apparatus, and at least partially overlaps the third and fourth elastic bodies in the radial direction as viewed in the axial direction.
A starting apparatus, comprising
- a pump impeller;
- a turbine runner;
- and
- a damper apparatus, wherein the damper apparatus includes:
- an input to which a torque from an engine is transferred;
- an output;
- a first intermediate element;
- a second intermediate element;
- a first elastic body configured to transfer the torque between the input and the first intermediate element;
- a second elastic body configured to transfer the torque between the first intermediate element and the output;
- a third elastic body configured to transfer the torque between the input and the second intermediate element;
- a fourth elastic body configured to transfer the torque between the second intermediate element and the output;
- and
- a fifth elastic body configured to transfer the torque between the first intermediate element and the second intermediate element,
- the third and fourth elastic bodies are disposed on an outer side of the first and second elastic bodies in a radial direction of the damper apparatus, and
- the fifth elastic body is disposed on the outer side of the first and second elastic bodies in the radial direction so as to be closer to the turbine runner than the first, second, third, and fourth elastic bodies in an axial direction of the damper apparatus.
