TORQUE ROD

摘要

A second inner member and a second insulator are provided in a second ring-shaped member forming a torque rod. A first bore section and a second bore section are provided in front of and in the rear of the second inner member. The insulator has an elastic arm section extending in the direction of a Y axis. A spring adjustment recess extends in a slit shape in the direction of an X axis from an end of the first bore section. The spring adjustment recess forms an unrestricted part of the elastic arm section by the second ring-shaped member, whereby the Z spring in the axial direction of the inner member is lowered, and the XZ spring ratio can be changed greatly while maintaining the size of the X spring in the main vibration inputting direction.

主权项

1. A torque rod comprising:
a rod main body of a long member, a small round section and a large round section which form a pair of vibration isolating connecting sections different in size, being provided in each end in the longitudinal direction of the rod main body, at least the large round section of the vibration isolating connecting sections including a ring-shaped member provided in the rod main body, an inner member arranged in a center portion of the ring-shaped member, and an insulator of an elastic body elastically connecting the inner member and the ring-shaped member, wherein, when a center axis of the inner member is a Z axis, a main vibration inputting axis orthogonal to the Z axis is an X axis, and an axis orthogonal to these Z axis and X axis is a Y axis, the insulator is provided with a spring adjustment recess so as to control a frequency of rigid body resonance in the direction of the Z axis at least by changing a spring ratio of a spring in the direction of the X axis to a spring in the direction of the Z axis.
