摘要： PURPOSE:To make a roller into smooth rolling as well as to check the occurrence of noise due to a collision between the roller and the inner wall of a rolling chamber. CONSTITUTION:A ring projecting part 16 is installed on the circumference of a roller 13. In addition, a recess guide part 18 is installed on an inner circumference of a rolling chamber 15. Likewise an elastic member 17 is attached to a top face of the ring projecting part 16 which is fitted in the recess guide part 18. In this time, this guide part 18 is formed so as to make the elastic member 17 come into resiliently contact with it in time of rolling of more than the setting angle of the roller 13. Any possible knocking noise is checked by a buffer action at a time when the elastic member 17 comes into resiliently contact with the recess guide part 18. Curved form of the rolling chamber 15 pertaining to the rolling motion of the roller 13 is easily and accurately formable by means of cutting or the like.

摘要： PURPOSE:To prevent the generation of the abnormal noise or the small vibration by suppressing the irregular displacement of a pendulum when the rotational speed of the power transmitting system is reduced. CONSTITUTION:A roller body 12 is slidably held by a guide member 13. The guide member 13 is rotatably provided in a roller chamber 11. The locus of the roller 12 is regulated in an arc-shaped manner by the guide member 13. Even when the rotational speed of the power transmitting system is reduced, the locus of the roller 12 is regulated by the guide member 13 to prevent the roller 12 from being displaced in an irregular direction.

摘要： PURPOSE:To make highly accurate and easy manufacturing able to be done as well as to reconcile an improvement in damping performance against a torsional vibration and a reduction in manufacturing cost by inserting each of both sides of a roller into the rolling guide holes of two plates in a state that a ring projection is interposed between these two plates, and connecting these two plates to a flywheel body. CONSTITUTION:In the case of a flywheel 1, an absorbing unit 4 in charge of absorbing a torsional vibration is formed separately from a flywheel body 3 and further its main member is constituted by plate material, so that aside from being easy in manufacturing, every part is formable in an accurate manner. In brief, since a part holding a roller 9 of a damping unit 4 is formed by a connecting plate 5 a pair of ring disks 7 and 8, after these plates are formed each by means of press molding, if they are riveted by two rivets 6, manufacturing can be done very easily in a highly accurate manner. Accordingly, when this flywheel 1 is adopted, an improvement in damping performance and a reduction in manufacturing cost are all achievable.

摘要： PROBLEM TO BE SOLVED: To reduce vibration produced by a propeller shaft by preventing occurrence of self-exciting whirling vibration caused by internal friction of a universal joint. SOLUTION: A propeller shaft assembly 1 is composed of a first shaft P1 having an axial length L1 , a second shaft P2 having an axial length L2 which is smaller than the first axial length L1 , and a universal joint C3 coupling the first and second shafts together. When the first and second shafts are arranged so as to define a crossing angle thererbetween, depicting a leftward convex shape with an apex at the position of the universal joint. Accordingly, a folding angle at the universal joint C3 , in particular, an folding angle θ3 at the universal joint C3 at a third uniform speed can be increased with the use of a secondary moment which is produced by a drive torque T when the input force to the propeller shaft 1 becomes larger, and accordingly, self-exciting whirling vibration caused by internal friction of the universal joint is prevented. Thereby it is possible to reduce vibration and noise produced by the propeller shaft 1, in particular, vibration and noise in a running condition in which the input torque becomes larger.

摘要： PURPOSE:To lessen the change of the angle made between a drive shaft and a propeller shaft even if an inclination occurs in a termination/reduction gear. CONSTITUTION:A termination/reduction gear 1 is suspended elastically on a car body at the fulcrums S1 and S2 on the straight line orthogonal to the composite torque vector T of the reaction torque TR around a drive shaft 2 and the reaction torque TP around a drive axle 5, and then an actuator 15, which rotates the termination/reduction gear 1 around the straight line which connects these fulcrums S1 and S2 with each other. Even if the termination/reduction gear 1 inclines by the composite torque T, the actuator 15 rotates the termination/ reduction gear 1 around the straight line which connects the fulcrums S1 and S2 with each other, so the change of the knuckle between the drive shaft 2 and the propeller shaft 7 can be lessened.

CONSTITUTION:The drive force of an engine, not illustrated, is transmitted to a drive shaft 2 through a propulsive shaft 9 and a universal joint 6, while the revolutions of this drive shaft 2 are reduced by a speed reduction device composed of a pinion 3 and a major gear 4, the direction being changed, and forwarded to the left and right output shafts 5, 5, and further transmitted to the axes 8, 8 coupled with the left and right drive wheels, not illustrated, via another universal joint 7. A final reduction device 1 is suspended by members 11, 12 coupled with the car bodyat the supporting points S1-S3. The roll shaft of the device 1 lies between the supporting points S1, S2, and the resultant torque supporting surface passing the point S1 passes by the car leftmore than the point S2, while the resultant torque supporting surface passing the point S2 passes by the car leftmore than the point S3.

摘要： PROBLEM TO BE SOLVED: To provide an engine mount controlling device capable of restraining selection-shocks due to range switching.
SOLUTION: A damping factor of an engine mount is made a damping factor in switching a range from a start of the range switching till a first predetermined time elapses. After the first predetermined time has elapsed, the damping factor is made a predetermined damping factor, so as to restrain shocks when the range is switched and control the damping factor to a damping factor suitable for a subsequent driving condition. When the range is switched a plurality of times, the predetermined time is set using an initial range switching as a reference.

摘要： PROBLEM TO BE SOLVED: To provide a power unit mount structure for a vehicle, suitable for forward-backward suppression of low-frequency wave generated at the vehicle.
SOLUTION: As a power unit 1, an engine 2 and a transmission 3 are transversely mounted in a vehicular front portion, elastically supported on a vehicle body 7 by a pair of mounts 5, 6 disposed in vehicle forward-backward positions and are configured such that a front wheel 20 is driven by the torque generated by the power unit 1. The mount 5 on the vehicle forward side is provided with a direction change mechanism (16) which applies an energizing force for switching to a vehicle advance direction to the power unit 1 when the power unit 1 rolls around a crankshaft 4 to be switched relatively to the upper direction. On the other hand, the mount 6 on the vehicle backward side is provided with the direction change mechanism (16) which applies an energizing force for switching to a vehicle advance direction to the power unit 1 when the power unit 1 rolls around the crankshaft 4 to be switched relatively to the lower direction.

摘要： PURPOSE:To reduce rotational change effectively, and to prevent impact noise by stabilizing a rolling track of a damper mass which rolls while showing the centrifugal swing of the pendulum. CONSTITUTION:In a fly wheel having a damper mass 5 which rolls along a rolling surface 2a in a rolling chamber 2 while showing the swing of the pendulum expanding outward in the direction of the diameter of a fly wheel main body 1, the rotation axis CD of the swing of the pendulum of the damper mass 5 is tilted in relation to the rotation axis CF of the fly wheel main body 1 under a condition that the both axes CD and CF exist in the same plane. The tilt angle theta is determined to a degree that the friction force between the damper mass 5 and the side surface 2b of the rolling chamber 2 is limited to a tolerance while stabilizing a rolling track of the damper mass 5.
