- the torque rod 10 according to the present embodiment, a large load load is input along the compression direction, and the increase in the amount of displacement along the load input direction of the inner cylinder bracket 14 is increased by the stopper fixture. Even when the amount of elastic deformation in the compression direction of the stopper elastic body 64 becomes large when it is limited by 46 and the stopper elastic body 64, the rigidity and dynamic spring constant of the stopper elastic body 64 increase rapidly. Therefore, it is possible to prevent a sudden drop in the ability to block impact load and vibration between the power unit and the vehicle body.
- a limit value is set for the amount of displacement of the power unit in the roll direction in order to reliably prevent the power unit from interfering with the vehicle when the power unit is displaced in the roll direction. Therefore, the torque rod 10 is required to limit the roll displacement of the power unit to the limit value or less when a load in the compression direction is input.
- the stopper fitting 46 when an excessive load load is input along the compression direction, and the stopper fitting 46 is displaced in the compression direction by a distance GL1 or more due to the load load to which the inner cylinder fitting 14 force is transmitted, the first load The abutting plate portion 50 of the staggered metal fitting 46 abuts against the distal end surface of the load receiving portion 60 through the covering portion 70, and the displacement of the staggered metal fitting 46 and the inner cylindrical metal fitting 14 in the compression direction is prevented. This ensures that the amount of displacement of the power unit in the roll direction is a predetermined limit value.
- the force described in the example in which the first load receiving surface 58 and the first load transmitting surface 54 and the second load transmitting surface 56 and the second load receiving surface 62 are parallel to each other. These don't have to be parallel.
- the elastic deformation generated in each of the outer body portion 66 and the inner body portion 68 of the stopper elastic body 64 at the time of load input has a shear deformation component as a main component (shear deformation component force, What should not be) That is, the angle between the first load receiving surface 58 and the first load transmitting surface 54 is 0 1-1, and the angle between the second load transmitting surface 56 and the second load receiving surface 62 is 0 1-2.
- the first load receiving surface 58, the first load transmitting surface 54, the second load transmitting surface 56, and the second load receiving surface 62 are parallel to the load input direction L. I explained an example, but they don't have to be parallel.
- the angle formed by the first load transmission surface 54 and the load input direction L is ⁇ 2-1, the second load If the angle between the transmission surface 5 6 and the load input direction L is ⁇ 2-2,
- ⁇ 3-1 ⁇ 30 ° and ⁇ 3-2 ⁇ 30 ° More preferably, ⁇ 3-1 ⁇ 30 ° and ⁇ 3-2 ⁇ 30 °.
- FIG. 4 shows a torque rod according to the second embodiment of the present invention.

This is basically the same as the torque rod 10 according to the first embodiment. For this reason, in the torque rod 90 according to the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
- a stopper fitting 92 is disposed in the hollow portion 22 so as to face the inner cylinder fitting 14.
- the stopper fitting 92 is disposed on the front side of the vehicle with respect to the longitudinal center in the hollow portion 22, and faces the front end surface of the inner cylindrical fitting 14 along the length direction of the device. Yes.

- the outer surface and the inner surface along the height direction of the device of the stagger fitting 92 are load transmission surfaces 94, respectively, and these pair of load transmission surfaces 94 are respectively in the length direction of the device (load input direction). ).
- the pair of load transmission surfaces 94 are inclined so that virtual straight lines IL1 and IL2 that are in contact with the pair of load transmission surfaces 94 intersect the downstream side of the stagger fitting 92 along the compression direction.
- the crossing angle 0 with respect to the load input direction is set appropriately within the range of 45 ° and less than 0 °.
- a load receiving surface 102 is formed on the inner peripheral surface of the hollow portion 22 so as to face the pair of load transmission surfaces 94 in the stopper fitting 92, respectively.
- Each of the pair of load receiving surfaces 102 is formed by a plane parallel to the pair of load transmitting surfaces 94.
- the angle between the load receiving surface 102 and the load transmitting surface 94 which is not necessarily parallel may be 0 ° or more and 45 ° or less.
- a stopper elastic body 96 is disposed between the outer cylinder fitting 12 and the stopper fitting 92.
- the stopper elastic body 96 has a substantially V-shaped cross-sectional shape that opens toward the front of the vehicle as a whole.
- the stopper elastic body 96 is formed with a main body 104 having a substantially rectangular cross section between the load transmitting surface 94 and the load receiving surface 102.
- the main body portion 104 has both end surfaces along the height direction vulcanized and bonded to the load transmission surface 94 and the load receiving surface 102, respectively, and elastically connects the stagger fitting 92 to the outer cylinder fitting 12.
- the stubber elastic body 96 is formed with a thin film-like first covering portion 106 and second covering portion 108 which are vulcanized and bonded to the abutting surface 98 and the rear end surface of the staggered metal fitting 92, and is hollow.
- a cushion portion 110 vulcanized and bonded to the rear end portion of the inner peripheral surface of the portion 22 is formed in a body.
- the first covering portion 106 vulcanized and bonded to the contact surface 98 is vulcanized and bonded to the front end surface of the inner cylinder fitting 14 in a neutral state where the main elastic body 36 is not elastically deformed.
- Covered part 4 Opposite with a predetermined interval GR at 0.
- the second covered portion 108 vulcanized and bonded to the front end surface of the stopper fitting 92 is vulcanized and bonded to the inner peripheral surface of the hollow portion 22 in a neutral state where the stopper elastic body 96 is not elastically deformed. It faces the tip of the cushion part 110 with a predetermined gap GL2.
- the torque rod 90 when the small displacement input along the load input direction of the inner cylindrical metal fitting 14 is small and when the vehicle is suddenly decelerated, the power unit is subjected to a shocking and extremely large pulling direction.
- the same operation as that of the torque rod 10 according to the first embodiment is performed to suppress the displacement of the power unit in the roll direction, and vibration and impact are transmitted to the vehicle body side. To prevent that.
- the pair of main body portions 104 in the elastic elastic body 96 that has received a load in the compression direction elastically deforms in the compression direction, respectively, and causes a restoring force corresponding to the amount of deformation to act on the inner tube fitting 14 as a reaction force. Limit the relative displacement of bracket 14 toward the rear of the vehicle.
- the main body portion 104 of the stopper elastic body 96 is vulcanized and bonded to the load transmitting surface 94 of the stopper fitting 92 and the load receiving surface 102 of the outer cylinder fitting 12, respectively.
- the main body 104 connects the stagger fitting 92 and the outer tubular fitting 12 in an inertia manner.
- each of the load transmission surface 94 and the load transmission surface 94 is formed by a plane that intersects at an intersection angle ⁇ set in a range of greater than 0 ° and not more than 45 °.
- the elastic deformation that occurs in the pair of main body portions 104 in the staggered elastic body 96 has a shear deformation component as a main component, and includes a small amount of compression / tensile deformation component as a secondary component with respect to the shear deformation component. Therefore, the deformation component of the strobe elastic body is mainly the compression deformation component. Compared to the case where it becomes a major component, even if the load in the compression direction increases, the ratio of compression and tensile deformation can be effectively suppressed from increasing rapidly, and the amount of deformation of the stagger elastic body 96 is large. Even when a load is input, it is possible to prevent the rigidity and dynamic spring constant of the strobe elastic body 96 from increasing rapidly with respect to an increase in input load.
- the torque rod 90 As a result, according to the torque rod 90 according to the present embodiment, as in the torque rod 10 according to the first embodiment, a large load is input along the compression direction, and the load on the inner cylinder fitting 14 is increased.
- the increase in displacement along the input direction is limited by the stopper fitting 92 and the stopper elastic body 96, even if the amount of elastic deformation in the compression direction of the stopper elastic body 96 becomes large, the stopper elastic body 96 Since the rigidity and the dynamic spring constant can each be prevented from increasing suddenly, it is possible to prevent a sudden drop in the ability to block the impact load and vibration between the power unit and the vehicle body.
- the ratio of the compression / tensile deformation component in the elastic deformation of the stagger elastic body 96 is changed. For example, if the crossing angle ⁇ is set to a sufficiently small value, the ratio of the compression-tensile deformation component in the elastic deformation of the strobe elastic body 96 can be sufficiently reduced, and the ratio of the shear deformation component can be reduced. It can be big enough.
- the ratio of the compression 'tensile deformation component in the elastic deformation in the strobe elastic body 96 is increased and the compression is performed. Since the static spring constant of the stubber elastic body 96 with respect to the load in the direction also increases, the compression of the inner cylinder fitting 14 and the stopper fitting 92 when a large load is input can be achieved by increasing the compression / tensile deformation ratio to some extent. An increase in the amount of displacement in the direction can be effectively suppressed.
- the stopper elastic body 96 As the amount of deformation increases, the rigidity of the stopper elastic body 96 and the rate of increase of the dynamic spring constant also increase.Therefore, the crossing angle ⁇ should be 30 ° or less in consideration of the ability to block the vibration and impact of the torque rod 10. It is preferable to set.
- an excessive load is input along the compression direction, and the stopper fitting 92 is spaced by a distance GL2 or more in the compression direction due to the load that also transmits the inner cylinder fitting 14 force.
- the front end face of the stopper metal 92 abuts against the tip of the cushion part 110 via the second covering part 108, and the displacement of the stopper metal 92 and the inner cylinder metal 14 in the compression direction is prevented. This ensures that the amount of displacement of the power unit in the roll direction is a predetermined limit value.
- FIG. 5 shows an example of a load damage diagram in the case where load loads in the compression direction and tension direction are applied to the torque rod 10 according to the first embodiment of the present invention. Has been.
