Abstract

A vehicle damper device may include: a first plate coupled to a crankshaft of the engine; a second plate coupled via an elastic body to the first plate; an inertia body coupled to the second plate; a support member coupled to the crankshaft along with the first plate; a bearing inserted between the support member and the inertia body; a third plate coupled to the inertia body; a fourth plate coupled to an input shaft of the power transmission device; and a torque limiter mechanism disposed between the third plate and the fourth plate, the torque limiter mechanism being disposed at a position on a radially inner side than the elastic body and not axially overlapping with the elastic body, the elastic body being a coil spring disposed in an outer circumferential portion of the first or second plate, and the elastic body being an arc-shaped arc spring.

First claim

The invention claimed is:

1. A vehicle damper device disposed on a power transmission path between an engine and a power transmission device, comprising:
a first plate coupled to a crankshaft of the engine;
a second plate coupled via an elastic body to the first plate;
an inertia body coupled to the second plate;
a support member coupled to the crankshaft along with the first plate;
a bearing inserted between the support member and the inertia body;
a third plate coupled to the inertia body;
a fourth plate coupled to an input shaft of the power transmission device; and
a torque limiter mechanism disposed between the third plate and the fourth plate,
the torque limiter mechanism being disposed at a position on a radially inner side than the elastic body and not axially overlapping with the elastic body,
the elastic body being a coil spring disposed in an outer circumferential portion of the first or second plate, and
the elastic body being an arc-shaped arc spring.

2. The vehicle damper device of claim 1 , wherein
an electric motor is coupled in a power transmittable manner to the input shaft, and wherein
the torque limiter mechanism is disposed at a position on a radially inner side than a coil end of the electric motor and not axially overlapping with the coil end.

3. The vehicle damper device of claim 1 , wherein a second bearing is inserted between the fourth plate and the support member.
