An antivibration device capable of securing a thickness dimension of a stopper rubber without changing a gap between a connecting member and a stopper wall portion. A connecting member includes a base surface and a receding surface located to recede beyond the base surface in a direction to go away from a stopper wall portion, the base surface and the receding surface face the stopper wall portion, and a stopper rubber includes an inner fitting portion at which the connecting member is internally fitted. Thus, it is possible to secure a thickness dimension of the stopper rubber without changing a gap between the connecting member and the stopper wall portion.

According to the present invention, there is provided a vibration damping device (10) including a first bracket (11) and a second bracket (12), a first attachment member (14), a second attachment member (15), and an elastic body (16). The second attachment member (15) includes an insertion cylinder portion (22) in which the second bracket (12) is inserted. The insertion cylinder portion (22) is provided with a stopper portion (56) which faces a stopper wall (55) provided in the first bracket (11), in a radial direction (Y) in a side wall portion (57) oriented outward in the radial direction (Y) of the insertion cylinder portion (22). The stopper portion (56) includes a first stopper portion (61) and a second stopper portion (62) which are disposed in a manner of being displaced in an axial direction (X) of the insertion cylinder portion (22). The first stopper portion (61) is constituted by a first elastic portion (58). The second stopper portion (62) includes a rigid member (25). A first distance (D1) between the first stopper portion (61) and the stopper wall (55) in the radial direction (Y) is equal to or shorter than a second distance (D2) between the second stopper portion (62) and the stopper wall (55) in the radial direction (Y).

A structure for mounting an engine mount, may include bracket which is coupled to the engine mount, and may have at least one mounting hole; an insulator which may have a pipe shape having a center hole, includes a material having elasticity, and is fitted into the at least one mounting hole; and a fixing pipe which is fitted into the center hole, and mounted in the at least one mounting hole together with the insulator, in which a recessed portion having a partially cut out shape or a recessed shape is formed along a circumference of the insulator at a first side of the insulator.

A vehicle includes a side support extending in a vehicle longitudinal direction, a drive unit spaced apart from the side support in a vehicle lateral direction, where the drive unit includes a crankshaft extending in the vehicle lateral direction, and a spacer member positioned between the side support and the drive unit in the vehicle lateral direction, where the spacer member coupled to one of the drive unit and the side support, and the spacer member is detached and spaced apart from the other of the drive unit and the side support, and where the spacer member is positioned rearward of the crankshaft in the vehicle longitudinal direction.

An assembly bearing arrangement for a motor vehicle includes an assembly bearing having a bearing housing, a vibration-damping bearing, and a bearing core connectable to a power train element. The bearing housing is connected with a body-fixed carrier part by a first fastening element, oriented in a direction that differs from a vertical direction, in a torsion-resistant manner, and by a second fastening element, oriented substantially in the vertical axis direction. A U-shaped stop bracket bridges the bearing core and is firmly connected to the bearing housing. The bearing core is formed with diametrically opposite stop arms, which in basic position are spaced from legs of the stop bracket by a gap distance. A first stop buffer is arranged on inner surfaces of the stop bracket and/or the bearing core, and second stop buffers are arranged on the legs of the stop bracket and/or the stop arms between the legs and the stop arms.

A unit bearing includes a bearing body configured to be received by a rigid bearing housing provided with an opening on at least one side, a carrier element and at least one support member engaging the rigid bearing housing through the opening. The bearing body includes elastomer abutments. The elastomer abutments are disposed between the rigid bearing housing and the support member. The carrier element is disposed between the support member and the elastomer abutments. The unit bearing is configured such that relative movements of the bearing body with respect to the bearing housing caused by loading of the support member along three mutually orthogonal directions are limited by the elastomer abutments.

Various embodiments provide a bush for isolating vibrations, the bush comprising: a first anchor part defining a longitudinal axis; a second anchor part disposed coaxially with respect to the first anchor part; a first resilient body operably engaged with the first anchor part; a second resilient body operably engaged with the second anchor part; and an inertial mass element disposed between the first anchor part and the second anchor part. The inertial mass element is independently connected to the first resilient body and the second resilient body. Also, the first resilient body, second resilient body and inertial mass element are arranged to isolate vibrations between the first anchor part and the second anchor part within a predetermined operational frequency range. Further, the inertial mass element is arranged to isolate the first anchor part and second anchor part from dynamic stiffness increases associated with eigenmodes of the first resilient body and the second resilient body in the predetermined operational frequency range.

According to the vibration isolation unit, a first projection provided on an outer member is inserted through a first attachment hole in the stopper. By attaching the first fixing member larger than the first attachment hole to the end of the first projection, the stopper is fixed to the vibration isolation device. The stopper is sandwiched between the first fixing member and the outer member.

An engine mount bracket has a U-shape body with a web and a front and rear leg. The legs includes bores to receive fasteners to secure the bracket to the engine block. The web includes a bore to receive a hydraulic mount shaft. A surface on the bracket receives a body portion of the hydraulic mount to restrict motion of the hydraulic mount.
