Embodiment Construction

[0032] Next, referring to the drawings, a liquid-filled engine mount 1 (an example of a vibration damping device for a vehicle) according to an embodiment of the present invention will be described. Arrows U and Lo appropriately shown in the respective figures indicate the upper side and the lower side of the engine mount 1 , respectively.

[0033]

[0034] refer to figure 1 An engine mount 1 is provided between an internal combustion engine 2 (an example of a first member) and a vehicle body 3 (an example of a second member) in a vehicle such as an automobile. The engine mount 1 is a component that supports the engine 2 while damping the vibration of the engine.

[0035] The engine mount 1 includes: a first attachment member 5 attached to the engine 2 , a second attachment member 6 attached to the vehicle body 3 , a The first wall 7, the second wall 8 arranged below the first wall 7, the partition wall 9 arranged between the first wall 7 and the second wall 8, the first l...

Abstract

The invention relates to a vibration damping device for a vehicle, which includes: a first attachment member attached to a first member; a second attachment member attached to a second member; a first liquid chamber and a second liquid chamber configured to change volumes according to relative displacement between the first attachment member and the second attachment member; and an orifice passage configured to cause a liquid to flow between the first liquid chamber and the second liquid chamber according to changes in the volumes of the first liquid chamber and the second liquid chamber. The liquid contains a non-Newtonian fluid whose viscosity decreases as a shear rate increases, the orifice passage includes a first communication port communicating with the first liquid chamber and a second communication port communicating with the second liquid chamber, and an opening area of the first communication port is different from an opening area of the second communication port.

Description

technical field [0001] The invention relates to a vibration damping device for vehicles. Background technique [0002] A known vibration damping device for a vehicle performs vibration damping by allowing liquid to flow between a plurality of liquid chambers through holes (for example, JP2004-324823A). [0003] In order to change the damping characteristics of the damping device according to the flow direction of the liquid, there is a configuration that a plurality of holes are provided, each hole has a check valve, and the holes through which the liquid flows are switched according to the flow direction of the liquid. However, if such a configuration is employed, the mechanism for changing the vibration damping characteristics of the vibration damper becomes complicated, and thus, the size and manufacturing cost of the vibration damper may increase. Additionally, durability issues may arise due to the multiple bores having moving parts such as check valves. Contents of ...
