Abstract: A bushing assembly for use in a suspension of an automotive vehicle. The bushing assembly is comprised of inner and outer cylinder members which are coaxial and spaced from each other. An elastic member and a rigid sleeve member are disposed between the inner and outer cylinder members. A sliding member is disposed between the inner cylinder member and the rigid sleeve member in order to reduce torsion spring effect of the elastic member. The sliding member is prevented from its axial displacement upon contacting with a radially outwardly extending retainer section formed in the inner cylinder member. Additionally, a generally cap-shaped seal rubber is provided to accomplish seal between the end section of the rigid sleeve member and the end section of the inner cylinder member. The seal rubber is located outside the inner cylinder member retainer section and spaced from the outer peripheral part of the inner cylinder member retainer section, thereby reducing resistance in relative rotation between the inner and outer cylinder members maintaining effective seal.

Abstract: A vibration absorber for an automotive vehicle which can prevent the shuddering phenomenon even while the vehicle is gradually accelerated or decelerated. The rubber member thereof is provided with multistep elasticity characteristics such that a first shearing portion of the rubber member is first deformed in shear, a second shearing portion thereof is next deformed in shear, and the other portion thereof is lastly deformed under compression. To achieve the above-mentioned elasticity characteristics, some appropriately sized slots, cavities, or gaps are provided within the rubber member at appropriate positions within the rubber member.

Abstract: An engine mounting arrangement includes elastomeric mounting blocks interposed between laterally extending arms connected to the engine and brackets fixed to a cross member of the chassis near the outboard ends thereof. The blocks are adapted to undergo shear upon the engine rolling about an essentially longitudinal axis. The arrangement further includes a mounting unit including an elastomeric chamber defining member which readily undergoes shear without changing the volume the chamber which it defines when the engine rolls but which undergoes a volume change upon the engine bouncing or vibrating in the vertical direction. The volume change pumps working fluid from the chamber to a second variable volume chamber and vice versa through a flow restriction so that vertical movement of the engine is strongly damped but rolling readily permitted. The arrangement further minimizes the transmission of vibration from the engine to the chassis and the tendency of the cross member per se to be vibrated.
