A vibration damping device including a vibration-damping device main unit attached to a bracket from a lateral side by a second attachment member being fitted to opposed walls provided on widthwise opposite sides of the bracket. The bracket includes flexible latches extending from the respective opposed walls forward in a direction of attachment. The second attachment member includes outer recesses respectively opening onto surfaces overlapped with the respective opposed walls. Each latch has a slope portion sloping inward in a width direction of the bracket such that a distal end face of the latch is inserted in the corresponding outer recess. The distal end face of the latch is latched by a forward wall inner face of the outer recess, and displacement of the second attachment member relative to the bracket in a direction of dislodgment opposite to the direction of attachment is limited.

A hydraulic damper for a mount assembly includes a housing and a subassembly. The housing defines a cavity and is integrally formed to include a plurality of retention features. The subassembly is at least partially disposed in the cavity and is secured relative to the housing by the plurality of retention features. At least one of the plurality of retention features and the subassembly is elastically deformable in a radial direction from an initial diameter to an elastically deformed diameter such that the subassembly is sized to axially pass by the plurality of retention features in the initial diameter for insertion of the subassembly into the housing and the plurality of retention members radially extend over the subassembly in the elastically deformed diameter to secure the subassembly relative to the housing.

A liquid composite spring for vehicles includes: a core shaft; an outer sleeve arranged on an upper portion of the core shaft, the upper portion of the core shaft being located inside the outer sleeve while the lower portion of the core shaft being located outside the outer sleeve; an upper liquid chamber formed in an upper portion of the outer sleeve, a lower end of the upper liquid chamber being connected to a top of the core shaft; and a lower liquid chamber formed in a lower portion of outer sleeve, the lower liquid chamber and the upper liquid chamber being connected with each other through a metal-rubber main spring. At least one flow channel body is provided in the metal-rubber main spring, so that liquid in the upper liquid chamber and liquid in the lower liquid chamber are communicated with each other through the flow channel body.

A liquid composite spring and a method for adjusting stiffness and damping property of the liquid composite spring such that the liquid composite spring includes an outer sleeve; a core shaft arranged around an upper portion of the outer sleeve. An upper portion of the core shaft is located inside the outer sleeve, while a lower portion extends out of the outer sleeve; an upper liquid chamber formed in an upper space inside the outer sleeve and having a lower portion connected to a top end of the core shaft; and a lower liquid chamber formed in a lower space inside the outer sleeve and connected with the core shaft.
