Title:
VIBRATION REDUCTION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2016125584
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration reduction device for a vehicle which is improved in vibration isolation performance by arranging rolling bodies so as to easily reciprocate by a torque variation.SOLUTION: A vibration reduction device for a vehicle is connected with a pendulum-type vibration reduction mechanism 11 in which an elastic vibration reduction mechanism 7 for reducing a variation of torque by the elasticity of an elastic body is connected to a crankshaft 2 of an engine 1 which combusts one time during one cycle of the crankshaft 2, and the variation of the torque is reduced by the reciprocation of a plurality of rolling bodies 13 of the elastic vibration reduction mechanism 7. The rolling bodies 13 are arranged at the pendulum-type vibration reduction mechanism 11 so that the number of the rolling bodies 13 whose angles θ between action directions di of inertia forces generated at the rolling bodies 13 by the variation of the torque out of a plurality of the rolling bodies 13 and gravity directions dg are within 90° becomes larger than the number of the rolling bodies 13 whose angles are lager than 90° when a piston 4 is on a top dead point.SELECTED DRAWING: Figure 1
