Definitions
- the present invention relates to a fluid transmission device including a dynamic damper and a centrifugal pendulum vibration absorber.
- this type of fluid transmission device includes a pump impeller connected to an input member coupled to a prime mover, a turbine runner that can rotate together with the pump impeller, an input element, the input element, and a first elastic body.
- a damper mechanism having an intermediate element to be engaged, an output element that is engaged with the intermediate element via a second elastic body, and is coupled to the input shaft of the transmission, and the input member and the input element of the damper mechanism are engaged.
- the elastic body of the dynamic damper and the mass body of the centrifugal pendulum type vibration absorber are arranged so as to overlap in the radial direction when viewed from the axial direction as in the conventional fluid transmission device, the axial length of the fluid transmission device increases. Therefore, it becomes difficult to make the entire apparatus compact.
- the elastic body of the damper mechanism and the elastic body of the dynamic damper are disposed between the turbine runner and the centrifugal pendulum type vibration absorber as viewed from the radial direction of the fluid transmission device, thereby suppressing an increase in the size of the fluid transmission device.
- the space for arranging the centrifugal pendulum vibration absorber can be secured sufficiently, and the degree of freedom in selecting the size (the length in the radial direction) of the mass body of the centrifugal pendulum vibration absorber can be increased. As a result, it is possible to realize a compact fluid transmission device that can effectively attenuate the vibration transmitted to the input member by the dynamic damper and the centrifugal pendulum vibration absorber.
- the damper mechanism may include a first elastic body and a second elastic body that are spaced apart in the radial direction as the elastic body, and the elastic body of the dynamic damper is Accordingly, the damper mechanism may be disposed between the first elastic body and the second elastic body. In this way, when the damper mechanism has the first and second elastic bodies on the inner peripheral side and the outer peripheral side, the first elastic body and the second elastic body of the damper mechanism when the elastic body of the dynamic damper is viewed from the axial direction.
- the first elastic body and the second elastic body By arranging the first elastic body and the second elastic body on the outer peripheral side of the damper mechanism in the region near the outer peripheral end of the turbine runner, which tends to be a dead space, the first elastic body and the second elastic body An arrangement space for the elastic body of the dynamic damper can be secured between the body and the body. As a result, the entire fluid transmission device can be made more compact.
- the resonance of the dynamic damper that is, the vibration generated when the vibration is attenuated by the dynamic damper can be suppressed by the centrifugal pendulum type vibration absorber. Therefore, according to this configuration, the vibration transmitted to the input member can be effectively damped by the dynamic damper and the centrifugal pendulum vibration absorber.
- the drive member 80 surrounds about half of the outer periphery of each first coil spring 81 disposed on the outermost periphery of the first and second coil springs 81 and 82 of the damper mechanism 8 so as to be slidably held.
- This is an annular member formed separately from the lock-up piston 90 of the lock-up clutch mechanism 9.
- the drive member 80 according to the embodiment includes an engagement portion 80 a that engages with the outer peripheral portion of the lockup piston 90, and a plurality of spring contact portions 80 b that abut against one end of the corresponding first coil spring 81. As shown in FIG.
- the mass of the centrifugal pendulum type vibration absorber 20 is ensured by sufficiently securing the arrangement space of the centrifugal pendulum type vibration absorber 20 while suppressing an increase in size of the fluid transmission device 1.
- the degree of freedom in selecting the size 22 can be increased.
