Definitions

  • the present invention relates to a torque rod for automobiles, and more particularly to a torque rod excellent in durability and easy to manufacture.
  • a bush including a pair of metal inner cylinders and an outer cylinder connected to an outer peripheral surface thereof via a rubber member is integrally interconnected by a connecting member.
  • the outer cylinder of the large bush and the outer cylinder and the connecting portion of the small bush are formed by press-molding a single annular metal plate.
  • a technique has been proposed in which the outer cylinder and the connecting portion are integrally formed and joined by spot welding at the connecting portion in which two plates are overlapped.
  • the present invention is to provide a torque rod having a pair of bushes whose axial directions are perpendicular to each other, particularly a torque rod capable of increasing the strength of an outer cylinder of a large-diameter bush.
  • the torque rod according to the present invention includes an inner cylinder and an outer cylinder, each of which has a large-diameter bush and a small-diameter bush that are perpendicular to each other in the axial direction. Is formed by a combined joined body by plastic working of two metal plates, and a protrusion protruding from the outer peripheral side of the outer cylinder of the large-diameter bush is formed.
  • the outer cylinder of the large-diameter bush is more preferably formed by bending a metal plate.
  • the outer cylinder of the small-diameter bush is formed by drawing on each metal plate.
  • a gap is formed along the longitudinal direction of the connecting member.
  • each of the connecting members is constituted by a combined joined body by plastic processing of two metal plates, and a protrusion protruding on the outer peripheral side of the outer cylinder of the large-diameter bush is formed.
  • the strength of the outer cylinder can be increased, and the rigidity can be improved in the direction in which the diameter of the outer cylinder is increased due to vibration such as torque from the vibration generating side member.
  • FIG. 1 is a side view showing an embodiment of a torque rod of the present invention
  • FIG. 2 is a cross-sectional perspective view showing a part of each bush.
  • the torque rod 1 shown in the figure has a bush having a pair of cylindrical inner cylinders 2, a rubber member 3 surrounding the inner cylinders 2, and an outer cylinder made of a metal material.
  • the bush is interconnected by a connecting member 4.
  • the pair of bushes includes a large-diameter bush 5 and a small-diameter bush 6 having different diameters, and the axial directions of the bushes 5 and 6 are connected perpendicularly to each other.
  • the large-diameter bush 5 is configured such that the rubber member 3 is directly fixed to the entire surface of the inner cylinder 2 and the upper cylinder 7 by the vulcanization adhesion or the rubber member 3 is press-fitted into the outer cylinder 7. Can be formed.
  • the outer cylinder 7 is formed with a bent portion 7a that holds the rubber member 3 between the upper and lower positions in the figure, and the bent portion 7a can prevent the rubber member from falling off.
  • the strength in the extending direction of the connecting member 4 as shown in FIG. 3 can be increased, and in particular, deformation of the storage dimension of the outer cylinder 8 that stores the rubber member 3 can be prevented.
  • the small-diameter bush 6 directly fixes the rubber member 3 to the inner cylinder 2 and the outer cylinder 8 by vulcanization adhesion.
  • Such a torque rod 1 can absorb, mitigate, or the like, transmission of vibration or the like during rotational driving from the inner cylinder side to the outer cylinder side, for example, by the rubber member 3.
  • the outer cylinder can exert a resistance against the force in the separation direction and the force in the proximity direction with respect to the inner cylinders.
  • the torque rod 1 is preferably formed by combining the connecting member 4 and the outer cylinders 7 and 8 into a desired shape by plastic working of two metal plates, and welding them together in a combined joined body. Since it comprises, it is not necessary to connect each outer cylinder and a connection member, Therefore It is not necessary to perform operations, such as positioning, reducing a number of parts, and can achieve cost reduction.
  • a projection 9 is formed on the outer diameter side of the outer cylinder 7 of the large-diameter bush 5, that is, at a position facing the connecting member 4 in the drawing.
  • the outer cylinder 7 of the large-diameter bush 5 is bent in the drawing to form a step by bending the metal plate.
  • the bent portion 7a can be formed by bending in the axial direction.
  • the amount of the metal plate drawn into the outer cylinder 7 of the large-diameter bush 5 is less than that of the outer cylinder of the large-diameter bush formed by the conventional drawing process, and the yield of the members is improved. Can be reduced.
  • the outer cylinder 8 of the small-diameter bush 6 is formed by drawing, and this configuration improves the yield and also prevents the large-diameter bush 5 from rotating off the shaft and preventing the axial bush from coming off.
  • the rigidity between the large diameter bush 5 and the small diameter bush 6 can be improved.
  • the drawing process can be performed by, for example, forming a seamless container with a bottom by tightening the outer periphery of a flat metal plate.
  • FIG. 4 is a side view showing another embodiment of the torque rod of the present invention.
  • the gap portion 10 is formed as large as possible in consideration of the strength of the connection member 4 along the longitudinal direction of the connection member 4. Can be reduced in weight.
  • the torque rod 1 is formed by simultaneously forming two outer metal plates by press forming, by pressing, an outer cylinder of a predetermined small-diameter bush, and an outer cylinder of a predetermined large-diameter bush by bending. While welding them at a position where they face each other, each bush can be obtained by press-fitting the inner cylinder and the rubber member into the narrowed portion and the bent portion of the 2-press weld bracket.
  • FIG. 5 is a side view showing another embodiment of the torque rod of the present invention.
  • ribs 11 projecting from the outer cylinder 7 to the outer peripheral side over the connecting member 4 are formed, and the connecting member 4 is provided with four ribs 11 at intervals of about 90 ° in the circumferential direction thereof.
  • the rigidity of the metal plate can be increased by increasing the section modulus of the metal plate located at the connecting portion.
