  • Patent number: 6155372
    Abstract: It is an object of the present invention to provide a suspension system for a power train in which vehicle vibration when idling can be reduced and thus improves in giving more comfort in riding in the vehicle.A power train assembled an engine and a transmission is supported by a left side mount, a right side mount, a front mount and a rear mount, from a body frame. The left side mount and the right side mount are located in the front direction than the vertical surface including the roll main axis of inertia of the power train.

  • Patent number: 6085858
    Abstract: In a suspension assembly for an automotive engine of a front-engine/front-drive vehicle and for supporting the engine to a frame by an engine mount, an arrangement position of the engine mount in the vehicle is in the range between a vertical plane including an inertia main axis in a rolling direction of the engine and a vertical plane including a centerline of a drive shaft. Then, the vertical plane including the inertia main shaft is not included in the range and the vertical plane including the centerline of the drive shaft is included in the range. Thus, the arrangement position of the engine mount may be set in consideration of all of the idle vibration property, the drivability and the degree of freedom of design.

  • Patent number: 5443280
    Abstract: An intermediate portion of a cylindrical suspension member collar extending in a longitudinal direction of a vehicle body is welded to an end portion of a suspension member in a transverse direction of the vehicle body. Both longitudinal-direction end portions of the suspension member collar are reduced in diameter in comparison with the intermediate portion thereof. The suspension member collar is disposed between respective inner cylinder portions of a pair of mounts so as to be coaxial with the inner cylinder portions. A shaft member is inserted into the inner cylinder portion of the mount and the suspension member collar, and a rubber bushing is disposed between an outer cylinder portion of the mount and the inner cylinder portion thereof, so that the outer cylinder portion and the inner cylinder portion can rotate relatively to each other. This makes it possible to prevent the rotation of the side member about an axial center thereof.
