A torque rod for straddling connection target members including a rod member and a rubber bushing provided to a lengthwise end of the rod member. The rubber bushing includes an inside shaft member, an outer peripheral member to be attached to one of the connection target members, and a rubber elastic body connecting the inside shaft member and the outer peripheral member. The rubber bushing is a part separate from the rod member and the end of the rod member is fixed to the inside shaft member. The rod member includes an abutting face to abut against the one of the connection target members without interposing the outer peripheral member of the rubber bushing. A stopper to limit an amount of elastic deformation of the rubber elastic body in the rubber bushing is constituted by including the abutting face of the rod member.

A transmission mount for a vehicle is capable of being press-fitted to a vehicle body side member with only an insulator, and without use of a bridge bracket, such that reduction in weight and cost can be achieved by eliminating the bridge bracket, and assembly workability can be improved by eliminating a bolting operation.

A system and method using a mount assembly for attaching a powertrain to a structural member of a vehicle. The mount assembly includes a first compliant member, a second compliant member, a first fluid chamber, a second fluid chamber, a pressure compliant membrane, electro-magnetorheological switch and a magnetorheological fluid. A fluid conduit interconnects the first fluid chamber with the second fluid chamber to allow a fluid to pass from the first fluid chamber to the second fluid chamber. The pressure compliant membrane seals the aperture in the second fluid chamber. The electro-magnetorheological switch is activated to generate an electric field in the fluid conduit to change the viscosity of the magnetorheological fluid to achieve a first stiffness profile of the mount assembly. The electro-magnetorheological switch is deactivated to remove the electric field in the fluid conduit to change the viscosity of the magnetorheological fluid to achieve a second stiffness profile of the mount assembly.

A roll rod for a vehicle includes: a front insulator connected to a powertrain; a rod bracket to mount the front insulator on a front end portion of the rod bracket; a case bracket disposed outside the rod bracket and fastened to a vehicle body; a stopping rubber formed at a rear end portion of the rod bracket and disposed in an inner space defined by the case bracket; and a rear insulator formed between the rod bracket and the case bracket, where the rear insulator is secured to an outer side surface of the rod bracket and an inner side surface of the case bracket. The roll rod enhances an insulation rate against vibration of a powertrain and improves durability while reducing manufacturing costs through the simple structure and application of an extrusion molding method.

A system and method using a mount assembly for attaching a powertrain to a structural member of a vehicle. The mount assembly includes a first compliant member, a second compliant member, a first fluid chamber, a second fluid chamber, a third fluid chamber, a pressure compliant membrane, and a valve. A fluid conduit interconnects the first fluid chamber with the second fluid chamber to allow a fluid to pass from the first fluid chamber to the second fluid chamber. The third fluid chamber has an opening in communication with the second fluid chamber and a vent port. The pressure compliant membrane seals the opening between the second fluid chamber and the third fluid chamber. The valve selectively seals the vent port in the third fluid chamber. A first stiffness profile of the mount assembly is selected by actuating the valve to open the vent port. A second stiffness profile of the mount assembly is selected by actuating the valve to close the vent port.

An active engine mount for a vehicle may include a support bracket connected to an engine; an actuator assembly integrally coupled to the support bracket and including a magnet and a coil that electromagnetically interact with each other; and a rubber assembly mounted to a vehicle body by a mounting bracket and configured to absorb vibration via a main rubber, wherein in a state in which the actuator assembly is located above the rubber assembly, a housing of the rubber assembly is fastened to the support bracket, and wherein the magnet is connected to the main rubber of the rubber assembly to enable transfer of force.
